Abstract:

- The present study analyses the relation among media influence, self esteem and body dissatisfaction in a group of preadolescent boys and girls. 243 preadolescents with the mean age of 12 were involved. The group consisted of 127 boys and 116 girls. They were asked to complete the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3; Thompson et al., 2004), the Body Shape Questionnaire (Dowson e Henderson, 2001) and the Rosenberg Self-Esteem Scale (Rosenberg, 1965). Preadolescent females reported higher levels of body dissatisfaction than preadolescent males. They also scored higher in three SATAQ-3 subscales: whether media are important source of information about being attractive, internalization of a media thin ideal and perceived media pressures to be thin. Body mass index and internalization of a thin ideal emerged as significant predictors of body dissatisfaction for both sexes. Perceived media pressures predict body dissatisfaction only among girls.Key words: media influence, self-esteem, body dissatisfaction, preadolescenceParole chiave: influenza dei media, autostima, insoddisfazione corporea, preadolescenza.

Abstract:

The purpose of this study was to examine the effect of a single bout of exercise on neurocognitive function in preadolescent children and young adults by determining the modulatory role of age and the neuroelectrical mechanism(s) underlying the association between acute exercise and executive function. Twenty preadolescents and 20 young adults completed the Stroop test, and neuroelectrical activity was recorded during two treatment sessions performed in a counterbalanced order. Exercise treatments involved moderate intensity aerobic exercise for 20 min as the main exercise and two 5 min periods of warm-up and cool-down. The control treatment participants read for a similar duration of time. Acute exercise improved participant reaction times on the Stroop test, regardless of Stroop congruency, and greater beneficial effects were observed in young adults compared to those in preadolescents. The P3 amplitudes increased after acute exercise in preadolescents and young adults, but acute exercise induced lower conflict sustained potential (conflict SP) amplitudes in preadolescent children. Based on these findings, age influences the beneficial effect of acute exercise on cognitive performance in general. Furthermore, the event-related brain potential differences attributed to acute exercise provide a potential clue to the mechanisms that differentiate the effects of acute exercise on individuals from preadolescence to young adulthood.

Abstract:

The article describes the experimental study of volitional qualities: perseverance and firmness in preadolescence. In our research were included 239 preadolescents. Perseverance and firmness were examined by applying Technique for the study of volitional qualities of personality (by Н. Стамбулова). The study results shoes that a few of preadolescents have a high level of perseverance and firmness under the expression of the expressivity and generalization factors. Boys are characterized by a higher level of development of perseverance and firmness under expression of expressivity factor, meanwhile at girls we identify a higher level of development of perseverance and firmness under expression of generalization factor. The high level of perseverance and firmness under expression of expressivity factor prevails at 13 years old preadolescents, while the same qualities, under expression of the generalization factor is more developed at 14–15 years old preadolescent.

Abstract:

Growing up in a high family risk (HFR) environment is accompanied by difficulties in executive functions (EFs) and interpersonal skills (IS) that may persist into adulthood. Because preadolescence is a critical period, this study will assess a multicomponent mediational intervention program, to determine the possibility of improving these skills. There were 61 preadolescent participants, between the ages of 8 and 12; 34 were associated with HFR and 27 were associated with low family risk (LFR). All the participants were tested with EF and IS measures. Results showed that, prior to treatment, the HFR preadolescents had poorer performance on EF and IS than did the LFR preadolescents. In the posttreatment measures, to assess the utility of the multicomponent program, the HFR preadolescents group was able to match the scores of those in the LFR group. In addition, intervention effects in the HFR group were maintained in the follow-up assessment.

Abstract:

The purpose of this study is to capture a snapshot of the lives of Brazilian preadolescents and gain a deeper understanding of the variables that influence compliance with parental rules. This analysis draws from the São Paulo Legal Socialization Study, a cohort study (N = 800; age = 11 years) from public and private schools. Descriptive statistics provide a perspective on normative Brazilian parenting practices and preadolescents’ perceptions of parental legitimacy across multiple domains. Hierarchical linear modeling revealed that procedural justice, global legitimacy, issue-specific legitimacy, and disciplinary techniques all significantly predicted compliance across issues and between preadolescents. Parents who used constructive disciplinary practices paired with procedural justice practices were more likely to be perceived as legitimate authorities and to have their preadolescent children comply with their rules. Our findings broaden the literature on constructive parenting practices in preadolescence, and allow for greater generalizability of current Western research to a diverse metropolitan setting in Brazil.

Abstract:

Because the preadolescent's inner world is still undeveloped and insufficiently enriched by the experience of experiencing critical situations that stand in the way of meeting important needs, his activism, aimed at overcoming them, is not stimulated. Therefore, in difficult situations the preadolescent includes the defense mechanisms. When the mechanisms prove to be inefficient, the body instinctively looks for a way out and often finds it in the external environment. Psychoactive substances can be used as external procedures to defend against the psychotraumatic situation and the vulnerability of preadolescents to drug use is directly related to the fact that drugs have become accessible, the consumption being often associated with the pressure exerted by the group of friends.

Abstract:

Studies of preadolescents strongly suggest that the prevalence of depression and suicidal activity among them has been seriously underestimated. The authors review current thinking about preadolescent suicide; discuss its implications for clinicians, supervisors, and agency administrators; and recommend a research agenda to guide and support effective practice with preadolescents at risk for suicide.

Abstract:

Resourcefulness is a set of cognitive-behavioral self-control skills for coping with stress to maintain quality of life. However, research examining precursors in the development of resourcefulness in preadolescents is scant. A cross-sectional approach was used to investigate hypothesized predicting effects of intrinsic contextual factors (children’s age, gender, and school performance), extrinsic contextual factors (parents’ age, gender, education, income, and resourcefulness), and process regulators (academic stress and dispositional optimism) in a convenience sample of 361 preadolescent–parent dyads. Results show that preadolescents’ process regulators, academic stress, and dispositional optimism were significant predictors of resourcefulness. The findings suggest that preadolescents’ resourcefulness was greatly influenced by process regulators, which are cognitive perceptions intervening the use of resourcefulness. Further research with various study designs is needed to examine additional factors that may influence resourcefulness in large and more diverse child–parent samples.

Abstract:

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were conceptualized and constructed based on existing theories. Study I checked the suitability of these items among preadolescent and adolescent age groups. After revisions, Study II was done to evaluate the item properties using item response theory. Subsequently done Confirmatory Factor Analysis provided evidence for the construct validity of the new measure. Finally, Study III was done to develop the age wise and gender wise norms for preadolescent and adolescent age groups. The newly developed measure was found to have sufficient reliability and validity and hence can be widely applied for measuring mental rotation of preadolescents and adolescents.

Abstract:

Background Maternal obesity and physical inactivity have been identified as correlates of overweight and obesity and physical inactivity in older preadolescents; however, no study has explored this relationship in Hispanic preadolescents. Furthermore, the relation between maternal physical activity (PA) and blood pressure (BP) in Hispanic preadolescents has not been examined. Purpose This study aimed to assess the associations between Hispanic mothers’ PA and body mass index (BMI) and their preadolescents’ PA, screen time, BP, and BMI. Methods Data of 118 mother-child (aged 2–10 years) dyads enrolled in a cross-sectional study of metabolic syndrome in Hispanic preadolescents at a community health center in Johnson City, TN were used. Parent and child questionnaires were used to ascertain mothers’ BMI and PA and preadolescents’ PA and screen time. Preadolescents’ height, weight, and BP were measured. Multiple logistic regression was used to examine the association between child and maternal variables, adjusting for mother’s education and the child’s sex and age. Results Pradolescents of obese mothers were more likely than preadolescents of mothers with normal weight to engage in less than three days of at least 60 min of vigorous PA per week (OR: 6.47, 95% CI [1.61–26.0]). Preadolescents whose mothers did not engage in moderate PA were more likely to engage in less than three days of at least 60 min of vigorous PA per week (OR: 2.92, CI [1.18–7.24]); and have elevated BP (OR: 2.50, 95% CI [1.02–4.53]) than preadolescents whose mothers engaged in moderate PA. Discussion Our results show a negative relationship between maternal obesity and preadolescent PA, and a positive relationship between lower maternal PA and elevated BP and lower PA in Hispanic preadolescents. This suggests that interventions aimed at improving Hispanic preadolescents’ PA and BP may use maternal PA and maternal BMI (for preadolescent PA) as a modification strategy to improve health in Hispanic preadolescents.

Abstract:

Purpose In this study, the authors compared coarticulation and lingual kinematics in preadolescents and adults in order to establish whether preadolescents had a greater degree of random variability in tongue posture and whether their patterns of lingual coarticulation differed from those of adults. Method High-speed ultrasound tongue contour data synchronized with the acoustic signal were recorded from 15 children (ages 10–12 years) and 15 adults. Tongue shape contours were analyzed at 9 normalized time points during the fricative phase of schwa-fricative-/a/ and schwa-fricative-/i/ sequences with the consonants /s/ and /ʃ/. Results There was no significant age-related difference in random variability. Where a significant vowel effect occurred, the amount of coarticulation was similar in the 2 groups. However, the onset of the coarticulatory effect on preadolescent /ʃ/ was significantly later than on preadolescent /s/, and also later than on adult /s/ and /ʃ/. Conclusions Preadolescents have adult-like precision of tongue control and adult-like anticipatory lingual coarticulation with respect to spatial characteristics of tongue posture. However, there remains some immaturity in the motor programming of certain complex tongue movements.

Abstract:

Abstract Objectives Parents play an important role in keeping their children safe. However, this becomes more difficult during preadolescence as children seek greater autonomy away from the direct supervision of adults. The current study focused on preadolescent youth (10–13 years) and examined parent–child disagreements about safety, with a focus on determining if child temperament attributes moderate the relation between how parents learn of these and resolve these disagreements. Methods A short-term longitudinal design was used. Parents and children retrospectively recalled safety disagreements together and then independently completed questionnaires about these. Parents then tracked disagreements over 1 month. Results The behavioral attributes of inhibitory control and risk-taking propensity both moderated the relationships between parental source of knowledge of safety disagreements and subsequent methods of resolution. Conclusion Safety-promotion messaging for parents of preadolescents may need to be tailored based on child attributes to maximize effectiveness.

Abstract:

Background: This study aimed to examine whether sedentary digital media use in preadolescence increases the risk of being overweight 3 years later, and whether this association differs based on preadolescents’ leisure-time physical activity (LTPA) levels. Methods: The authors conducted a 3-year follow-up study among 4661 participants with a mean (SD) age of 11 (1) years at baseline and 14 (1) years at follow-up. A web-based questionnaire assessed sedentary digital media use and LTPA. The authors categorized baseline LTPA duration into 3 levels: 0 to 5 (low), 6 to 8 (moderate), and ≥9 (high) hours per week. In addition, the authors categorized adolescents as normal weight or overweight/obese at follow-up. Results: Greater amounts of sedentary digital media use at baseline associated with an increased risk of being overweight 3 years later even after adjusting for confounders. This only held for preadolescents with low baseline LTPA (OR = 1.14; 95% confidence interval, 1.05–1.24), but not among those with moderate (OR = 1.02; 0.91–1.15) or high (OR = 0.96; 0.85–1.08) LTPA. Conclusions: Preadolescent LTPA modified the long-term association between sedentary digital media use and being overweight; specifically, 6 hours per week or more of LTPA mitigated the increased risk of being overweight associated with higher amounts of digital media use.

Abstract:

The use of ergogenic aids is common in sport, even among preadolescent athletes (8,15,25). The aim of this study was to investigate the relationship between preadolescents’ use of nutritional ergogenic aids (creatine and amino acids) and gender, age, athletic participation, and sport-relevant psychological factors (i.e., sport success motivation, task and ego orientation, self-efficacy). Two thousand four hundred fifty 11- to 13-year-old children participated in this study. Results suggest that substance use increases with age, especially among male preadolescents; that gender differences are particularly marked among older preadolescents; and that a high commitment to sport training represents a risk factor of ergogenic supplementation only when it is linked to certain psychological dispositions, such as a high ego orientation and a low task orientation.

Abstract:

Background Athlete’s heart is a term used to describe the morphological and functional changes in the hearts of athletes. Recent studies suggest that these changes may occur even in preadolescent athletes. This study aims to improve our understanding of the changes occurring in the preadolescent athlete’s heart. Design and methods Cardiac morphology and function in 76 preadolescent cross-country skiers (aged 12.1 ± 0.2 years) were compared with 25 age-matched non-competing preadolescents. Echocardiography was performed in all subjects, including 2D speckle-tracking strain echocardiography and 3D echocardiography. All participants underwent cardiopulmonary exercise testing to assess oxygen uptake and exercise capacity. Results Athletes had greater indexed VO2 max (62 ± 7 vs. 44 ± 5 mL/kg per min, p < 0.001), indexed left ventricular end-diastolic volume (79 ± 7 vs. 68 ± 7 mL/m2, p < 0.001), left ventricular mass (69 ± 12 vs. 57 ± 13 g/m2, p < 0.001), indexed right ventricular basal diameter (28.3 ± 3.0 vs. 25.4 ± 3.5 mm/m2, p < 0.001) and right atrial area (10.6 ± 1.4 vs. 9.7 ± 1.2 cm2/m2, p < 0.01). There was no difference in left ventricular ejection fraction, global longitudinal strain, and global circumferential strain and right ventricular fractional area change between the groups. Controls had higher right ventricular global longitudinal strain (−28.1 ± 3.5 vs. −31.1 ± 3.3%, p < 0.01). VO2 max was highly correlated to left ventricular end-diastolic volume ( r = 0.76, p < 0.001). Conclusion Athletes had greater left ventricular mass and greater left and right ventricular chamber dimensions compared with controls, while left ventricular function did not differ. Interestingly, right ventricular deformation was significantly lower compared with controls. This supports the notion that there is physiological, adaptive remodelling in preadolescent athlete’s heart.

Abstract:

Preadolescence is a critical period, characterised by changes in physical, hormonal, cognitive, behavioural, and emotional development, as well as by changes in social and school relationships. These changes are accompanied by the transition from elementary school to middle school. The literature shows that this transition is one of the most stressful events for preadolescents, which can have a negative impact on their well-being. The main objectives of this review, focused on the school context, were to identify protective and risk factors influencing the well-being of preadolescent students and to describe the interventions implemented. A systematic search of peer-reviewed papers published between 2011 and 2021 was conducted following the PRISMA reporting guidelines. A total of 36 full-text articles met the inclusion criteria. Studies converge in identifying risk factors that may affect student well-being in this age group: individual factors (levels of emotional awareness and self-esteem) and relational factors (friendship, teachers’ and parents’ supporting actions and roles). Intervention programs are mainly focused on improving emotional and social regulation skills that also influence academic achievement. Our findings have important implications for both research and intervention in school settings.

Abstract:

Confusion exists with regard to the substantive difference between self-concept and self-esteem. In an endeavour to cast some light on this confusion two studies were conducted with 1193 preadolescents using modified versions of two commonly used instruments designed to measure self-concept and self-esteem. Exploratory factor analysis indicated that both these instruments measure specific facets of the same construct, namely self-concept. General or global self-concept proved to be a difficult construct to measure in preadolescent students.

Abstract:

This paper compares the tendency to express autonomy in 20 Estonian, 20 Swedish, and 20 Swedish Estonian middle-class families with preadolescent children during videotaped family mealtimes. The results indicate that compared to the Swedish participants, participants from both Estonian samples expressed autonomy less frequently. Being talkative does not always mean expressing more autonomy. The Swedish preadolescents who were the most talkative and whose mothers were talking less, were more likely to express their personal needs, opinions and preferences. Possible reasons of cultural variability in autonomy orientation are discussed.

Full text

Abstract:

Attention deficit disorder with hyperactivity (ADHD) is a common comorbidity in children with Tourette syndrome (TS). However, motor restlessness and high levels of sensorimotor activation or “overactivity” may be a feature of TS rather than a distinct ADHD comorbidity. The link between overactivity and ADHD in TS has yet to be established and in particular between adult and preadolescent manifestations. The current study furthers this understanding of ADHD features in TS by investigating the relationship between cognitive and behavioral aspects of ADHD and TS. The style of planning (STOP) overactivity scale was compared in preadolescent (n=17) and adult (n=17) samples. The STOP overactivity scale measures the characteristic overactive style of planning in everyday life. The aims of the study were twofold as follows: (1) to see if an overactive style was present in adolescents as well as in adults, and (2) to see if this overactive style correlated with hyperactivity, impulsivity, or perfectionism. Results suggest that overactivity may be a better description of the hyperactivity manifestations in TS. Behavioral components of overactivity were present in preadolescents while the cognitive components were more frequent in adults. Overactivity relates at the same time to perfectionism and impulsivity.

Abstract:

Purpose: This study sought to determine whether healthy, overweight, and obese preadolescents living in low-income neighborhoods differ in regards to body image and weight control behaviors. It is critical to identify early precursors to body image issues so that optimal prevention programs can be implemented. Subjects: The sample consisted of 64 preadolescents ages 8 to13 years, including 29 male (45%) and 35 female (55%) fourth, fifth, and sixth graders living in low-income neighborhoods in Fresno, California. Measures: (a) Height and weight were measured to calculate BMI-for-age (kg/m2 ), and (b) the CDC 13- question Body Image Survey was administered. Analysis: ANOVA was used to compare differences in body image and weight control behaviors by weight category (healthy, overweight, obese).Results: The obese group reported more body image dissatisfaction than did the healthy and overweight groups. Obese preadolescents were less happy with their body image and dieted more than healthy weight preadolescents. Overweight preadolescents were more similar in behaviors to healthy weight preadolescents than obese preadolescents. Conclusions: Low self-esteem related to weight may be exacerbated in the adolescent years when new pressures and challenges emerge. Targeting preadolescent overweight and obese individuals with body image issues may be useful in ameliorating some of the problems that are magnified in adolescence, such as dieting and eating disorders.

Abstract:

Coronary heart disease is presently one of the leading causes of death In adults in many countries, including in Indonesia. It is well known that elevated levels of cholesterol in children are closely associated with hypercholesterolemia and coronary heart disease in adult life. This study was conducted in an attempt to find a preliminary insight of the magnitude of the problem of hypercholesterolemia In children In Indonesia as a developing country. The blood lipid levels of 54 preadolescent boys from well-Io-do families were analyzed. Two-third of those children were shown to have elevated blood cholesterol level, and even one third or 16 out of 54 preadolescents boys investigated suffered from hypercholesterolemia. We conclude that elevated blood cholesterol level is frequently found among large-framed and obese Indonesian children.

Abstract:

The article elucidates the problem of the relationship between the level of psychological resilience and self-esteem in preadolescents. It is argued that the high and medium levels of psychological resilience will correlate with the high level of self-esteem, and the low level of psychological resilience will correlate with the low level of self-esteem. Preadolescence is a difficult age, with many risks, physical, physiological, and mental changes, internal and external conflicts. The successful crossing of this stage depends on the level of psychological resilience it manifests. One of the determining factors for a high personal psychological resilience of preadolescents is their positive self-attitude, stable adequate self-esteem, on which self-confidence is based, an optimistic outlook on future prospects and desires. It must be borne in mind that self-esteem exists in the absence of self-humiliation and, together with the latter, acts as a protective function in preadolescents.

Abstract:

Families and schools are important environments that contribute to the resilience and positive development of preadolescent children. Sense of mastery, including its two central factors of optimism and self-efficacy, forms an important component of resilience during preadolescence (Prince-Embury, 2007). This study examined the interrelationships between family functioning, school connectedness, and sense of mastery in 75 children (46 girls and 29 boys) from a government school in Melbourne, Australia. Data was gathered from students aged 10 to 12 years through three self-report questionnaires. Negative perceptions of family functioning were significantly associated with the resilience factors of low sense of mastery, optimism, and self-efficacy. Higher school connectedness was significantly associated with greater sense of mastery, optimism, and self-efficacy. Additional evaluation revealed school connectedness to partially mediate the relationship between family functioning and sense of mastery. School connectedness appears to be a protective factor against the negative influence of poor family functioning. Findings highlight the important role of school connectedness in preadolescent resilience, as measured in terms of mastery, and suggest that interventions directed to enhance school connectedness are of value, particularly for children from poorly functioning families.

Abstract:

Background: Cardiometabolic disease (CMD) risk often begins early in life. Healthy lifestyle behaviors can mitigate risk, but the optimal combination of behaviors has not been determined. This cross-sectional study simultaneously examined the associations between lifestyle factors (fitness, activity behaviors, and dietary patterns) and CMD risk in preadolescent children. Methods: 1480 New Zealand children aged 8–10 years were recruited. Participants included 316 preadolescents (50% female, age: 9.5 ± 1.1 years, BMI: 17.9 ± 3.3 kg/m2). Fitness (cardiorespiratory fitness [CRF], muscular fitness), activity behaviors (physical activity, sedentary, sleep), and dietary patterns were measured. Factor analysis was used to derive a CMD risk score from 13 variables (adiposity, peripheral and central hemodynamics, glycemic control, and blood lipids). Results: Only CRF (β = −0.45, p < 0.001) and sedentary time (β = 0.12, p = 0.019) were associated with the CMD risk score in the adjusted multivariable analysis. CRF was found to be nonlinear (VO2 max ≤ ≈42 mL/kg/min associated with higher CMD risk score), and thus a CRF polynomial term was added, which was also associated (β = 0.19, p < 0.001) with the CMD risk score. Significant associations were not found with sleep or dietary variables. Conclusion: The findings indicate that increasing CRF and decreasing sedentary behavior may be important public health targets in preadolescent children.

Abstract:

Background There is a lack of nationally representative estimates for the consequences of early childhood undernutrition on preadolescent outcomes in India. Understanding this relationship is helpful to develop interventions that not only prevent child undernutrition but also mitigate its consequences. Methods and findings In this cohort study, we analyzed prospectively gathered data from 2 waves of the India Human Development Survey (IHDS) to investigate the association of undernutrition during early childhood (0 to 5 years) in 2004 to 2005 with physical and cognitive outcomes during preadolescent (8 to 11 years) years in 2011 to 2012. These surveys interviewed 41,554 households across all 33 states and union territories in India in 2004 to 2005 and reinterviewed 83% of the households in 2011 to 2012. Primary exposure was assessed using the Composite Index of Anthropometric Failure (CIAF) based on 2004 to 2005 survey. Primary outcomes were short stature (height-for-age z-score [HAZ] <−2), thinness (body mass index [BMI] <18.5 kg/m2), reading, and arithmetic skills during preadolescence based on the 2011 to 2012 survey. Survey-weighted generalized linear models were used, and effect modification based on child sex and sociodemographic variables were evaluated using 3-way interaction terms. Of the 7,868 children included in this analysis, 4,334 (57.3%) were undernourished. Being undernourished was associated with increased odds of short stature (odds ratio [OR] 1.73, 95% confidence interval [CI] 1.45 to 2.06) and thinness (OR 1.52, 95% CI 1.33 to 1.73) during the preadolescent period, while it was associated with decreased odds of achieving a higher reading (cumulative odds ratio [cumOR]: 0.76, 0.66 to 0.87) and arithmetic (cumOR: 0.72, 0.63 to 0.82) outcomes. The disparity in outcomes based on CIAF increased with age, especially for female children. Increased level of female education within the household reduced the disadvantages of undernutrition among female children. Study limitations include observational and missing data, which limit our ability to draw strong causal inferences. Conclusions In this study, we found that early child undernutrition was associated with several adverse preadolescent physical and cognitive outcomes, especially among female children. Improved female education mitigates this association. Female education promotion should assume a central role in Indian public health policy making.

Abstract:

Introduction: Unlike adult gliomas, the utility of combined application of awake anesthesia and intraoperative neurophysiological monitoring (IONM) for maximal safe resection in eloquent region gliomas (ERG) has not been established for pediatric population while it remains unexplored in preadolescents (below 11 years old). Case Presentation: We report 2 cases of awake craniotomy with IONM in an 8 and 9 year old for safe maximal resection of ERG. In both the cases, repeated preoperative visits of the operating room was performed to familiarize and educate the children about intraoperative communication, comfortable positioning, and neurological assessment. Under conscious sedation protocol, cortical and subcortical mapping, and electrocorticography, gross total resection was achieved. In both the cases, there were no postoperative neurodeficits or perioperative complications. Conclusion: Our 2 cases illustrate the first instance of successful use of awake IONM for maximal safe resection of ERG in preadolescent age-group. We believe, with proper preoperative planning and careful titration of anesthetics, it is safe and feasible. The blanket notion that preadolescent age-group should be excluded from awake mapping needs to be challenged, rather curated on a case basis.

Abstract:

The crisis of public spaces implies a closure to the private sphere and, as a consequence, the inanity of the education processes. Space privatization involves the supremacy of the “οίκος” (house) on the “αγορα” (public space), so that the house assumes the role of an enclosed community. The effect of this closure is a weakening of the spatial identification and socialization of preadolescents and the exclusion of differences and relationships with their peers. This break prevents and reduces the autonomous exploration of the space as a place of free expression, the communicative acting, the conflict. This article analyzes the efficacy of the educative role of the quarter and its incidence on the preadolescent development from a sheltered to an open space both through a deep relationship with the environment and an aptitude to explore the external world. The validity of these hypotheses has been proved through a study carried out in three cities.

Abstract:

Background: The prevalence of anterior cruciate ligament (ACL) injuries increases during maturation and peaks during late adolescence. Previous studies suggested an age-related association between participation in injury prevention programs and reduction of ACL injury. However, few studies have investigated differences in biomechanical changes after injury prevention programs between preadolescent and adolescent athletes. Purpose/Hypothesis: The purpose was to investigate the influence of age on the effects of the FIFA Medical and Research Centre (F-MARC) 11+ injury prevention warm-up program on differences in biomechanical risk factors for ACL injury between preadolescent and adolescent female soccer players. It was hypothesized that the ACL injury risk factors of knee valgus angle and moment would be greater at baseline but would improve more after training for preadolescent athletes than adolescent athletes. It was further hypothesized that flexor-extensor muscle co-contraction would increase after training for both preadolescent and adolescent athletes. Study Design: Controlled laboratory study. Methods: Institutional Review Board–approved written consent was obtained for 51 preadolescent female athletes aged 10 to 12 years (intervention: n = 28, 11.8 ± 0.8 years; control: n = 23, 11.2 ± 0.6 years) and 43 adolescent female athletes aged 14 to 18 years (intervention: n = 22, 15.9 ± 0.9 years; control: n = 21, 15.7 ± 1.1 years). The intervention groups participated in 15 in-season sessions of the F-MARC 11+ program 2 times per week. Pre- and postseason motion capture data were collected during 4 tasks: preplanned cutting, unanticipated cutting, double-legged jump, and single-legged jump. Lower extremity joint angles and moments were estimated through biomechanical modeling. Knee flexor-extensor muscle co-contraction was estimated from surface electromyography. Results: At baseline, preadolescent athletes displayed greater initial contact and peak knee valgus angles during all activities when compared with the adolescent athletes, but knee valgus moment was not significantly different between age groups. After intervention training, preadolescent athletes improved and decreased their initial contact knee valgus angle (–1.24° ± 0.36°; P = .036) as well as their peak knee valgus moment (–0.57 ± 0.27 percentage body weight × height; P = .033) during the double-legged jump task, as compared with adolescent athletes in the intervention. Compared with adolescent athletes, preadolescent athletes displayed higher weight acceptance flexor-extensor muscle co-contraction at baseline during all activities ( P < .05). After intervention training, preadolescent athletes displayed an increase in precontact flexor-extensor muscle co-contraction during preplanned cutting as compared with adolescent intervention athletes (0.07 ± 0.02 vs –0.30 ± 0.27, respectively; P = .002). Conclusion: The F-MARC 11+ program may be more effective at improving some risk factors for ACL injury among preadolescent female athletes than adolescent athletes, notably by reducing knee valgus angle and moment during a double-legged jump landing. Clinical Relevance: ACL prevention programs may be more effective if administered early in an athlete’s career, as younger athletes may be more likely to adapt new biomechanical movement patterns.

Abstract:

Parental practices such as inconsistent discipline, psychological control, and imposition have been linked to the development of internalizing and externalizing problem behaviors in preadolescents. This study aimed to identify the association these practices had on Mexican preadolescent problem behaviors through Structural Equation Modeling. The sample consisted of 306 elementary students from three public schools in Mexico City (age M = 10, SD = 0.92). Students completed subscales from the Parental Practice Scale, the Alabama Parenting Questionnaire, and the Strengths and Difficulties Questionnaire. Paternal imposition and maternal psychological control were significant predictors for internalizing problems, while inconsistent discipline was a significant predictor of externalizing problems. The results highlight that although parental practicevalues might differ across cultures, their association to problem behaviors are similar.

Abstract:

In this paper, Gergely Kunt analyzes the collaborative diary writing of two preadolescent boys from the period of the Hungarian Revolution of 1956, during which they decided to act as reporters and writers to create their own chronicles of the events transpiring between October 1956 and March 1957. Twelve-year-old Gyula Csics and thirteen-year-old János Kovács were close friends and neighbors in a tenement house in Budapest, which resulted in their collaborate project of writing and illustrating their own diaries in an attempt to record the events of the Hungarian Revolution. During this collaborative project, they would read and copy each other’s diaries, which primarily focused on public events, rather than the preadolescents’ private lives. In addition to their handwritten entries, the two boys illustrated their diaries with drawings that depicted street fights or damaged buildings, as well as newspaper clippings and pamphlets, which they had collected during and after the Revolution.

Abstract:

This study focuses on the relationship between preadolescents and youtubers, with the objective of observing how tweens integrate youtubers as referents of a teen digital culture. From a socio-psychological and communicological perspective, a mixed methodological design was applied to carry out the audience study, which was divided into two parts: a quantitative analysis of the audience via a survey administered to 1,406 eleven-twelve year old students of Catalan Secondary Schools, and a qualitative analysis of the preadolescence audience using three focus groups. The quantitative data was analysed with SPSS and the qualitative data with the help of the Atlas.ti software. The results demonstrate that tweens consider youtubers as referents for entertainment and for closeness to a teen digital culture, but not really as a role models or bearers of values as influencers. Also, preadolescents show some dimensions of Media Literacy, since they recognise youtubers’ commercial strategies and their role as actors and professionals. The study notes gender bias in some aspects, and is an introduction to observation of the social functions of youtubers amongst teenagers, individuals who are in the process of constructing their identity and on the point of becoming young adults. El presente estudio se centra en la relación entre preadolescentes y youtubers, con el objetivo de observar cómo los primeros integran a los youtubers como referentes de una cultura digital juvenil. Desde una perspectiva sociopsicológica y comunicativa, se aplicó un diseño metodológico mixto para llevar a cabo el estudio de audiencia, organizado en dos partes: un análisis cuantitativo de la audiencia a través de un cuestionario administrado a 1.406 estudiantes de once-doce años de institutos en Cataluña, y un análisis cualitativo de la audiencia preadolescente a partir de tres «focus group». Los datos cuantitativos se analizaron con SPSS y los cualitativos con la ayuda del programa Atlas.ti. Los resultados demuestran que los preadolescentes consideran a los youtubers como referentes para el entretenimiento y por su proximidad a una cultura digital juvenil, pero no realmente como modelos o portadores de valores en tanto que «influencers». Además, los preadolescentes muestran alguna dimensión de Alfabetización Mediática, al identificar las estrategias comerciales de los youtubers y sus roles profesionales. El estudio da cuenta de un sesgo de género en algunos aspectos, y resulta una introducción a la observación sobre las funciones sociales de los youtubers entre los adolescentes, personas que están en pleno proceso de construcción de sus identidades y a punto de convertirse en jóvenes adultos.

Abstract:

The contributions of self-monitoring and gender to preadolescent friendship expectations were explored in a sample of 200 fifth, sixth, seventh, and eighth grade students. Chum pairs were identified on the basis of mutuality and stability in order to examine relationships between dyads in friendship expectations. Goals of the study were essentially exploratory because of the limited data base on self-monitoring in children. Girls had higher levels of self-monitoring and were more likely to be part of a chum pair. Younger students were more likely to expect overt expressions of friendship. The relationship predicted between dyads in their level of self-monitoring, as found in adult friendships, was not present in preadolescents. Certain trends in the friendship expectations of high and low self-monitors were suggestive of the conceptual understanding of the self-monitoring construct.

Abstract:

Whereas the adolescent brain is a major target for gonadal hormones, our understanding of hormonal influences on adolescent neural and behavioral development remains limited. These experiments investigated how variations in the timing of testosterone (T) exposure, relative to adolescence, alters the strength of steroid-sensitive neural circuits underlying social behavior in male Syrian hamsters. Experiment 1 simulated early, on-time, and late pubertal development by gonadectomizing males on postnatal d 10 and treating with SILASTIC brand T implants for 19 d before, during, or after adolescence. T treatment before or during, but not after, adolescence facilitated mating behavior in adulthood. In addition, preadolescent T treatments most effectively increased mating behavior overall, indicating that the timing of exposure to pubertal hormones contributes to individual differences in adult behavior. Experiment 2 examined the effects of preadolescent T treatment on behavior and brain regional volumes within the mating neural circuit of juvenile males (i.e. still preadolescent). Although preadolescent T treatment did not induce reproductive behavior in juvenile males, it did increase volumes of the bed nucleus of the stria terminalis, sexually dimorphic nucleus, posterodorsal medial amygdala, and posteroventral medial amygdala to adult-typical size. In contrast, juvenile anterodorsal medial amygdala and ventromedial hypothalamus volumes were not changed by preadolescent T treatment yet differed significantly in volume from adult controls, suggesting that further maturation of these brain regions during adolescence is required for the expression of male reproductive behavior. Thus, adolescent maturation of social behavior may involve both steroid-independent and -dependent processes, and adolescence marks the end of a postnatal period of sensitivity to steroid-dependent organization of the brain.

Abstract:

BACKGROUND: Musculoskeletal disorders are one of the major health hazards among farmers. Pre-adolescents are mainly associated with agricultural work due to poor socioeconomic conditions. OBJECTIVES: This study aims to implement a new ergonomics aid for the betterment of job procedures and improvement of productivity, health, and safety of the preadolescent farmers. METHODS: 100 male and 100 female preadolescent farmers were randomly selected from the villages of Tarakeswar, West Bengal, India, to evaluate and reduce work-related musculoskeletal disorders, physiological stress. Modified Nordic questionnaires, Body Part Discomfort (BPD) scale, and handgrip strength were assessed before and after using the ergonomics aid. RESULTS: The results of the study show that there was a significant change (decrease) in discomfort in the lower back, wrists, shoulder, and hands among preadolescent farmers when using the newly designed ergonomic aid. Handgrip strength increased and physiological stress was decreased among preadolescent farmers in post-intervention than pre-intervention in just after work conditions. Productivity has been increased in farming by decreasing absenteeism from work with the use of ergonomic aid. CONCLUSION: This study concludes that productivity has been increased in farming by decreasing absenteeism from work as well as by using the ergonomic aid the discomfort feeling has been decreased markedly.

Abstract:

Cognitive Behavioural Therapy (CBT) for preadolescent children with obsessive compulsive disorder (OCD) is typically derived from adult cognitive behavioural models of OCD; however, it is unknown whether these adult models apply to preadolescent children. This systematic review examined whether 11 cognitive, behavioural and familial maintenance mechanisms identified from adult cognitive behavioural models of OCD and descriptions of how family factors may maintain OCD applied to preadolescent children with obsessive compulsive symptoms/disorder (OCS/OCD; Prospero:CRD42019153371). PsycINFO, MEDLINE and Web of Science Core Collection were searched in March 2019, with forward citation handsearching conducted in March/April 2020. Twenty-nine studies were synthesised. Studies were identified for only six of the 11 proposed maintenance factors. Of the cognitive and behavioural factors, only inflated responsibility and meta-cognitive beliefs showed evidence of independent and/or specific associations with childhood OCS. Of the family factors, only less frequent displays of parental confidence, positive problem solving and rewarding of children’s independence showed some evidence of specificity to childhood OCD. Notably, findings across studies were inconsistent and existing studies have considerable methodological limitations. Experimental and prospective longitudinal studies are needed to determine whether the proposed factors maintain childhood OCS/OCD, to improve the effectiveness and efficiency of CBT for preadolescent children with OCD.

Abstract:

Purpose. Children with ADHD have known behaviors of hyperactivity and impulsivity which may result in adverse outcomes. The purpose of this study is to examine the association of serious adverse outcomes (emergency department visits within the previous year) in preadolescents and adolescents with ADHD as compared with preadolescents and adolescents without ADHD. Method. The researchers conducted a cross-sectional, secondary data analysis of National Health Interview Survey (NHIS) 2017 data concerning 2,965 children (>11 to 17 years). The NHIS data resulted from face-to-face interviews of a household member selected from a multistage area probability design representing households in the US. Data analyses for this study included Chi-square bivariate analyses and logistic regression analyses. Results. There were 13.2% of children in the sample who had ADHD. Children with ADHD were more likely to be male and non-Hispanic white. They were also more likely to have one or more additional disease or condition excluding ADHD. In adjusted logistic regression analysis on emergency department utilization by ADHD status, the adjusted odds ratio was 1.93 (95%CI: 1.35, 2.74; p = 0.0003) for preadolescents and adolescents with ADHD as compared with preadolescents and adolescents without ADHD. Conclusion. Children with ADHD were more likely to have emergency department utilization than children without ADHD. Preventive medical visits were similar between preadolescent and adolescent children with and without ADHD. Characteristics associated with ADHD may explain the increased need for emergent care. Developing interventions for children with ADHD may decrease emergency department utilization.

Abstract:

Body dissatisfaction (BD) is a common experience among preadolescent girls and a robust risk factor and precursor to eating pathology (EP). Although the relationship between BD and EP has been well documented, there is less research exploring the factors that may make this relationship more or less pronounced. In the current study, we investigated several factors that may moderate the relationship between BD and EP. Preadolescent girls ( n = 169) aged between 10 and 12 years completed questionnaires measuring EP, BD, negative affect, perfectionism, self-esteem, teasing, and perceived pressure from others and the media. Moderator analyses indicated that self-oriented and socially prescribed perfectionism, media pressure, and self-esteem each moderated the relationship between BD and EP. These factors may potentially make a preadolescent girl more susceptible to developing EP and may be useful to address in targeted prevention efforts among girls dissatisfied with their bodies.
