Abstract Background: Prevalence of PCOS is increasing among Indian women due to growing changes in environment and lifestyle and also due to awareness of symptoms and willingness to seek medical help. Six out of ten females diagnosed with PCOS are teenage girls. Studies have shown that the women with PCOS often suffer from psychiatric comorbidities including depression but the data regarding the prevalence of depression in adolescent Indian girls with PCOS are scarce. Aim: To find out the prevalence of depression and its associations among adolescent Indian girls with PCOS. Methods: This was a cross sectional, case-control study conducted in the Endocrinology department of a speciality hospital of North India. We evaluated 160 newly diagnosed adolescent PCOS girls aged between 13-19 years, diagnosed by Revised Rotterdam criteria. Control group included 80 healthy, age matched, non-PCOS girls. Detailed history, Anthropometric measurements and standard hormonal evaluation were done. Depression was assessed by administering Patient Health Questionnaire-Adolescents (PHQ-A), a self-administered questionnaire based on DSM IV criteria. PHQ-A score of >10 was considered as the threshold for significant depression. Statistical evaluation was done with SPSS and P value of <0.05 was significant. Results: Mean age of the patients was 16.3 +/- 3.2yrs. The frequencies of significant depression in PCOS and control groups were 36.5% and 11.9% respectively. PCOS adolescents having higher HOMA-IR value (p-0.03), higher hirsutism score (P-0.01) and higher BMI (p-<0.01) had a higher risk of significant depression. Menstrual irregularity, acne, dyslipidaemia, serum testosterone, 17-OHP, prolactin and serum TSH levels had no significant correlation with depression. Discussion: PCOS commonly prevails during adolescence, a phase when girls are more concerned about their physiology and physical health. Negative body image and chronic stress can lead to disturbed mental health. Our study by using a simple and patient friendly clinical tool the PHQ-A has found higher prevalence of depression (almost 3 times) in Indian adolescent PCOS girls as compared to controls and it significantly corelates with insulin resistance, hirsutism and obesity. PCOS puts tremendous burden, on both physical as well as mental health, especially in adolescents, due to its effects on physical appearance, self-esteem, fertility and also due to other long term metabolic complications associated with it. PCOS is an urgent health problem that needs careful assessment and appropriate treatment of its all aspects. Timely recognition of mental health issues in these girls can help with early interventions including referral to mental health specialists (if needful) and add to the wellbeing of these young girls. Conclusion: The initial evaluation of PCOS in adolescent girls should also include the assessment of mental health disorders.

(1) Background: Healthy teenagers are often sleepy. This can be explained by their physiology and behavioral changes; however, the influence of CO2 concentration above 1000 ppm should not be neglected with respect to sleep dissatisfaction. (2) Methods: CO2 concentrations were measured in two similar bedrooms occupied by girls aged 9 and 13 years old. The scheme of measurements included random opening and closing of the bedroom doors for the night. Additionally, the girls evaluated their sleep satisfaction in a post-sleep questionnaire. (3) Results: During the night, the CO2 concentration varied from 402 to 3320 ppm in the teenager’s bedroom and from 458 to 2176 ppm in the child’s bedroom. When the bedroom doors were open, inadequate indoor air quality (IEQIII and IEQIV categories) was observed in both the teenager’s and child’s bedroom during 11% and 25% of the night, respectively; however, closing the doors increased the contribution of moderate (IEQIII) and low (IEQIV) categories of air to 79% and 86%, respectively. The girls were dissatisfied only when the bedroom door was closed. The satisfied category of sleep was selected only by the younger girl. (4) Conclusions: Opening the bedroom door during the night can decrease the CO2 concentration 55–64% without reducing thermal comfort.

Background/Aims Adolescent girls in Tanzania may drop out of school if they experience an unwanted pregnancy. Evidence shows that sex education can improve adolescents’ understanding of issues related to intercourse, pregnancy and contraception, but this education is lacking in Tanzania. In order to improve sex education in Tanziania, this study investigated early adolescents’ knowledge of anatomy, changes during puberty, pregnancy, contraception and safety. Methods This cross-sectional study was conducted among randomly selected 10−14-year-old students in a primary school in Bagamoyo, Tanzania. A questionnaire was used to gather data on participants’ knowledge of fundamental anatomy and physiology, sexual characteristics and contraception. Quantitative data were analysed using descriptive and inferential statistics, with P<0.05 used to determine significance. Results A total of 111 students (44 girls, 67 boys, from the fifth and sixth grades) participated. Significantly more boys than girls had begun talking to classmates about steady girl/boyfriends across both grades (P=0.003). The participants’ understanding of basic anatomy (including the functions of the heart, lungs and digestive system) was mostly high, although they scored low in some areas (pain, dentistry and facial muscles). When asked about pregnancy, contraception and safety, significantly more boys than girls could correctly identify appropriate contraception for teenagers (P=0.01). When analysed by grade, the boys’ grade had a significant impact on whether they correctly answered the questions on pregnancy (P=0.001) and contraception (P=0.001), but there were no differences in answers between girls of different grades. Conclusions Girls’ knowledge of pregnancy, contraception and safety was significantly lower than the boys, and despite beginning sex education in sixth grade, no significant differences in were observed between the fifth and sixth grade answers by the girls. The comprehensive sexual education programme for adolescent girls in Tanzania needs urgent improvement.

Adolescence is defined by growth, change, and the presence of new chances, and it is often associated with reproductive health problems. In teenage girls, reproductive organ healthcare is expected to prevent significant problems. Preventing vaginal discharge or fluor albus is one of the aims of treatments of reproductive organs in teenage girls. Vaginal discharge or fluor albus is a discharge from the tiny glands in the vagina and cervix that may or may not smell and lead to a local itching. The causes of vaginal discharge or fluor albus may be normal or physiologic. According to 2012 data from the Indonesian Demographic and Health Survey (IDHS), around 18% of women aged 15-49 years had encountered the vaginal discharge or fluor albus. This socialization has the objective of educating teenage girls about vaginal discharge or fluor albus. The strategy is to provide direct socialization through counseling and leaflet distribution, while also following the health protocols. The activity occurred on july 12, 2021. The results of the socialization obtained data on knowledge about vaginal discharge or fluor albus from 46 students before being given socialization with good knowledge of 15 people (32.6%) and after the socialization, there was an increase in students with good knowledge of vaginal discharge or fluor albus as many as 44 students ( 95.7 percent ). Proves an increase in awareness of vaginal discharge or fluor albus before and after socialization. Suggestions for educators to regularly educate students about reproductive health, either in cooperation with health education organizations or with other health authorities.

Menstruation is a natural biological process through which every female has to go through during her life. It is part of reproduction of life. Most of the females menstruate two to seven days every month. Unawareness about menstruation creates the discrimination and misconception among the females mainly during teenage. Taboos, stigma and myths thwart adolescent girls and boys to gain knowledge about menstruation and take it as a positive part of life. 40 % of the world’s population, or 3 billion people, do not have a handwashing facility with water and soap at home. 43 % of schools lacked a handwashing facility with water and soap affecting 818 million school-age children. As per World Bank indicator 65% of population is residing in rural areas of India. National Family Health Survey, India highlights that 41% of women with 10 or more years of schooling and in rural areas it is 33.7%. In India women are playing a vital role in rural economy but their contribution in agriculture and allied services is almost equal but it is unpaid and unaccounted only considered as their support in the family. Still there is gender inequality in rural areas; they have limited access in finance management, decisions related to education and healthcare issues. Most women are unskilled and no control on land and other productive assets of the family. Still traditions dominate in the issues related with women. In the present study awareness and behavioral pattern of rural women during menstruation is assessed in the study area. Structured questionnaire is used to get the response for awareness, availability, preference, purchase behavior of the women in the Bhogwar village of Uttar Pradesh. In the present study descriptive survey research design was applied and target respondents were selected through stratified random sampling. Consciousness among women on menstrual hygiene and uses of sanitary napkins is also explored. It is identified that the price plays a vital role in purchase behavior and maximum women are getting awareness through females of the family and school is major source of free napkins in study area.

Requirements for cellular homeostasis appear to be unchanged between childhood and maturity. We hypothesized, therefore, that the kinetics of O2 uptake (VO2) in the transition from rest to exercise would be the same in young children as in teenagers. To test this, VO2 and heart rate kinetics from rest to constant work rate (75% of the subject's anaerobic threshold) in 10 children (5 boys and 5 girls) aged 7–10 yr were compared with values found in 10 teenagers (5 boys and 5 girls) aged 15–18 yr. Gas exchange was measured breath to breath, and phases I and II of the transition and phase III (steady-state exercise) were evaluated from multiple transitions in each child. Phase I (the VO2 at 20 s of exercise expressed as percent rest-to-steady-state exercise VO2) was not significantly correlated with age or weight [mean value 42.5 +/- 8.9% (SD)] nor was the phase II time constant for VO2 [mean 27.3 +/- 4.7 (SD) s]. The older girls had significantly slower kinetics than the other children but were also found to be less fit. When the teenagers exercised at work rates well below 75% of their anaerobic threshold, phase I VO2 represented a higher proportion of the overall response, but the phase II kinetics were unchanged. The temporal coupling between the cellular production of mechanical work at the onset of exercise and the uptake of environmental O2 appears to be controlled throughout growth in children.

This article examines the phenomenology of the secondary benefits of anorexia, namely, the use of this symptom to suppress libido in adolescents and young girls with hypertrophied internal and external religious prohibition on the part of parents to manifest their growing sexuality, due to physiology. The causes of anorexia are described in many scientific works, but the peculiarities of the influence of religious attitudes of parents on the formation of anorexia in adolescents are poorly disclosed. This article reveals the psychological mechanisms (replacing aggression and secondary benefits) that keep the problem and make it impossible to achieve a result in the treatment of this ailment. The article presents a sample of those who applied to a psychological center for help from parents of adolescents suffering from anorexia and at the same time having strong religious prejudices, which, in our opinion, affects the occurrence and retention of a negative symptom under certain circumstances. For successful therapy and prevention of anorexia, we have established what circumstances can contribute to the occurrence of anorexia in adolescents from families with a strong religious orientation. The key point in working with the girls with whom we managed to conduct psychoanalytic sessions was their temporary disconnection from their religious beliefs until a conscious choice in the future. This serves as a prerequisite for an effective solution to the problem, since the existing doubts about religion, what is good / bad, right / wrong, create a certain neurotic pressure and can lead to consequences such as anorexia.

AbstractThe aim of the study was to present the relationships between the way of perceiving oneself and the world by young athletes, the cognitive anxiety and the ways of coping with stress. The target group consisted of 222 participants (114 boys and 108 girls) aged 16–20, students of sports-profiled secondary schools. The participants specialised in both winter and summer sports, as well as in individual and team sport disciplines. The following tools were implemented: Attitudes to Intrapersonal, Interpersonal and to the World Questionnaire, Coping Inventory for Stressful Situations (CISS) and Sport Anxiety Scale. The study showed that negative perception of oneself and others increases the level of cognitive anxiety and decreases the tendencies to search for social contacts in the face of stress. With regard to the positive image of oneself and others, the opposite was observed. The above relationships refer mainly to girls who practise sports.

Abstract Introduction Obstructive sleep apnea (OSA) and Asthma often coexist. There is some evidence that adults with asthma are more prone to developing OSA than the general population, as well as OSA may impact asthma control. Different than adults, OSA prevalence is equal in boys and girls, while puberty has strong influence in asthma, especially in pubescent girls. The objectives of this study were to analyze the prevalence of OSA in boys and girls and the impact of asthma severity in OSA prevalence. Methods Asthmatic children attending a tertiary pediatric pulmonology clinic performed clinical evaluation, Pulmonary Function Test, and Home Sleep Apnea Test. OSA was defined as habitual snoring and one or more obstructive respiratory events (OREI) per hour of recording. Control and severity of Asthma were evaluated according to Global Initiative for Asthma and puberal stage using Tanner figures for boys and girls Results We studied 80 consecutive patients, 7 to 18 years-old, mean age 11.6 years (SD: 2.7), 51.3% female. According to BMI z-score, nutritional status was: 2 (2.5%) underweight, 63 eutrophic (79%), and 15 obese (18.5%). Puberty was present in 17 volunteers. Pulmonary Function Tests were obtained from 71 volunteers, 45% presented obstruction pattern. Home Sleep Apnea Tests were available from 76 volunteers, with mean OREI of 1.8 events/h. OSA occurred in 69 volunteers (91%), while 66% were mild, 21% moderate, and 4% severe. We did not find associations of obstructive sleep apnea with sex or asthma severity. Conclusion OSA was highly prevalent among these asthmatic children, but most were mild. Sex and asthma severity were not associated to OSA. Considering the interrelationship of both diseases, it is worth to keep in mind the possibility of OSA among children and teenagers with asthma.

Abstract Measurements of maturity depend on the biological system considered since differences are often found in performance and body size in subjects of the same chronological age. The objective of this study was to identify associations between biological maturation, body morphology and physical performance in girls aged from 8.0 to 15.9 year-old and to verify the bone age in obese girls and compare it with chronological age. For that purpose 2040 (11.9 ± 2.3 years) school girls from Montes Claros, participated in this study. Regular anthropometric measures as height and body mass were taken. Triceps, biceps, subscapular, abdominal, suprailiac and calf skinfolds were also registered. Physical performance was assessed trough the test of a standing long jump, handgrip strength and 20 m multistage shuttle run. Maturational status, the average age at menarche and identification of PHV (maturity off set) were determined by means of the retrospective method. Girls with the BMI above the 95th percentile got their bone age evaluated through X-ray of the left hand/wrist, in accordance with the FELS method. It was possible to find an average age at menarche of 11.30 ± 0.70, while the average age at PHV was 12.17 ± 0.71 years of age. It was observed that both body composition and physical performance showed a tendency to increase with advancing age. However, when controlling the effect of maturation, despite having higher values in body composition the post-menarche girls group did not show higher levels of physical performance. In all age groups, obese girls showed mean rates of bone age higher than chronologic age (12.25 ± 2.09 and 14.09 ± 2.35, respectively, p=0.000). Chronological age should be used with caution when evaluating obese teenagers as it may underestimate biological age.

Little is known about the effects of different intensities of physical training on plasma leptin. This study examined the effect of two intensities of physical training on leptin in obese teenagers, and explored correlates at baseline and in response to 8 months of physical training. The participants were 55 obese youths 12-16 years of age who completed both baseline and posttesting. The youths were randomized to engage in lifestyle education only (LSE), moderate-intensity physical training and LSE, or high-intensity physical training and LSE. Baseline leptin was positively associated with fat mass. Girls had higher leptin levels at lower levels of fasting insulin than boys. The 8-mo physical training doses prescribed to obese teenagers did not result in significant group differences in mean change in leptin, although there was large variability in individual response. The change in leptin was inversely associated with baseline leptin and change in cardiovascular fitness. Diet, physical activity level, visceral adiposity, and glucose concentrations were not associated with leptin, neither at baseline nor in response to physical training. At baseline, total fat mass rather than visceral adiposity was associated with higher leptin levels. Over the 8-mo intervention period, regardless of group membership, youths who had the lowest increase in cardiovascular fitness tended to have the highest increase in leptin.

Background: Neonatal period is defined as a period from birth to under 4 weeks (<28 days) of age. It is a highly vulnerable time for an infant, who is completing many of the physiologic adjustments required for extra uterine existence. The term Respiratory distress (RD) is used to indicate signs & symptoms of abnormal respiratory pattern.
Methods: All neonates admitted in neonatal intensive care unit of Nepalgunj Medical College, Kohalpur with respiratory distress were included. Same number of age and sex matched controls without RD were selected.
Results: The NICU based hospital incidence of RD was 9.1% with male: female ratio 1.4:1 The Most Common etiology was neonatal sepsis (51.6%), followed by hyaline membrane disease (17.8%), TTN (12.7%), meconium aspiration syndrome (6%), birth asphyxia (5.08%), tracheoesophageal fistula (2%) and pneumothorax (2%). Newborns with poor APGAR score requiring resuscitation were more likely to develop RD (p=0.025). Newborns with birth weight <2.5 kg and >4 kg were 2 times likely to develop RD as compared to control group (p<0.012). There was 7 times higher risk of developing MAS when a baby was born through thick MSL as compared to control group (P<0.022). Inadequate ANC visit significantly increased RD in newborns (p<0.001). Babies born to mother with PROM for more than 18 hours were 5.5 times likely to develop RD (p<0.001) whereas those born to mother who had any source of infection were about 6 times at risk of developing respiratory distress than control group (p=0.007).
Conclusion: Certain measures that could be taken to reduce the number of RD are: 1. discouraging early marriage and teenage pregnancy. 2. Increasing awareness regarding temporary and permanent contraceptive measures. 3. Promoting education of girls. 4. Increasing coverage of ANC visit in rural areas and 5. formulating integrated plan and policies from the Government level.

AbstractGrounded in the Achievement Goal Theory framework of motivation and optimal functioning, there were two objectives of this study: (a) to test a model hypothesizing links between personal theories of school achievement, indices of the quality of academic engagement, wellbeing, and health-related behaviors, and (b) to explore whether the hypothesized model was invariant across gender groups. A multisection questionnaire pack tapping the targeted variables was administered to 967 teenagers (475 boys and 492 girls) aged between 11 to 16 years old. Structural equation modeling analysis revealed that Task theory of achievement predicted positively satisfaction in school and negatively boredom in school. An Ego theory of achievement was linked to higher levels of boredom in school. Satisfaction in school corresponded to higher life satisfaction, while boredom was negatively related. Higher life satisfaction was associated with lower tobacco, alcohol and marijuana consumption, more healthy food intake and greater levels of physical activity. The results revealed partial invariance of the model by gender. The quality of adolescents’ involvement in the classroom holds important implications for adolescent’s well-being and their health related behaviors. Interventions on the creation of a task-involving motivational climate in the school are proposed to promote healthy lifestyles among young people.

Abstract Introduction The COVID-19 pandemic has challenged researchers to use remote data collection. Our project includes determining DLMO phase, requiring a family-friendly without face-to-face interaction. We describe here our protocol, experiences, lessons learned, and findings from the first 15 participants. Methods Fifteen urban-dwelling children with moderate to severe persistent asthma [7 girls, ages 7 (n=1) to 10 years; and 8 boys, 8 or 9 years] and caregiver (CG) participated. CG tracked bedtimes and risetimes in daily diaries for 10-14 days; average bedtimes from 5 nights preceding saliva collection were used to determine timing for 10 half-hourly samples. CG and child were oriented and then watched a demo video. A “spit-kit” was delivered to the home the afternoon of the study. Kits included a small cooler bag with bottle of water, 10 numbered and 5 spare Salivette tubes (Starstedt, Germany), plastic bag, dark wraparound glasses with securing strap, and log sheet. Data collection began with a zoom call with staff, CG, and child to reiterate the instructions, answer questions, and observe the first sample. Thereafter, a staff member telephoned the caregiver every 30 minutes to prompt the next sample and query whether glasses had been kept on. CG placed kit outside the home for morning pick up. Samples were centrifuged and frozen (-20°) until sending to the assay lab (SolidPhase, Portland, ME) for melatonin radioimmunoassay (Alpco, Windham, NH). Results DLMO phase was determined with a 4pg/ml threshold for 11 children. DLMO phases (mtime=21:46±68 min) and average bedtimes (mtime=20:40±88min) were positively correlated (r=.87). Challenges identified for missed DLMOs included: one child supervised by a teenaged sibling (not CG); one child/CG identified as potentially uncooperative. The other two “misses” likely arose from low saliva quantity, inconsistencies with staff training, and inadequate description of requirements for wearing glasses. Procedure modifications included strategies tailored to families’ needs, experiences, and home environment that can challenge adherence to protocol, greater emphasis on wearing glasses, and cartoon reminder card and scales added to kit. Subsequent samples were successful. Conclusion Our approach was effective for determining DLMO phase in children using a remote approach with careful application of methods.

Abstract Introduction Although napping is very common and related to the outcome of individual development, the relationship between napping and health is not the same in different social and cultural contexts. In China, napping is considered as a healthy lifestyle and is often associated with better adolescent development outcomes. As a special group of teenagers (the academic level does not meet the requirements of ordinary high school), vocational high school students have a higher incidence of behavioral problems than ordinary high school students. Therefore, the purpose of this study is to explore the characteristics of napping and its relationship with behavioral problems in vocational high school students. Methods The napping questionnaire, Youth Self Report (YSR), general information questionnaire and other tools for covariates were used to measure 2505 high school students (62.04% boys, 37.96% girls, 16.71±0.02 years), recruited by convenient sampling. The relationship between nappingand behavioral problems was analyzed by multiple linear regression. Results 72.58% of the participants reported taking a midday nap at least three days per week during the past month, and 55.79% of our sample reported naps more than 30 minutes. Multiple regression analysis showed that nap frequency was negatively associated with high school students’ behavior problems after controlling for general characteristics and other important covariates. Compared with high school students who did not nap or napped less than 1 time/week, high school students who napped 1–2 times/week or 3–4 times/week had lower level of both internalizing behavior problems and externalizing behavior problems. There was no statistically significant association between nap duration and behavior problems. Conclusion This study finds that when napping is allowed, moderate frequency of napping is associated with lower level of internalizing and externalizing behavioral problems in vocational high school students, while nap duration is not significantly associated with behavioral problems. Further research is needed to explore the mechanism of the relationship between napping and behavior problems. Support (if any):

Menstrual hygiene is defined as the principle of maintaining the cleanliness of the body during menstrual flow. It requires basic facilities such as appropriate clothes, soakage material, water, soap, and toilet facilities with privacy. Many studies have revealed that most adolescent girls had incomplete and inaccurate information about menstrual hygiene and physiology. It also revealed that mothers, television, friends, teachers, and relatives were the main sources that provided information on menstruation to adolescent girls. In our study, most of the girls belong to the age group of 15 – 17 that is 448 participants are from that age group which comprises about 89% and they mostly belong to intermediate which is around 442 students (88.4%). 90.6% of the girls knew that menstruation occurs only in females and 88% of the girls aware that the best sanitary products are pads and only 39.6% of girls knew about menstruation before menarche. It was observed that only 37.2% of girls knew that infection would occur if they don’t clean their vagina regularly during their menstruation. Maximum that is 304 (60.8%) girls responded for dysmenorrhoea in the present study. The majority of these responses were in the age group of 13–15 years. the knowledge on menstruation and menstrual hygiene was found to be unsatisfactory although the practices were noted to be good. The majority of girls attained menarche in the study. Menstrual hygiene is an issue that needs to be addressed at all levels. In our study majority of the mothers were found to be illiterates, as mothers are the first informant to the majority of adolescent girls the health education actives can be extended to the mothers to improve awareness.

Introduction: According to traditional understanding of sodium homeostasis, nearly 100% of daily sodium (Na) intake is excreted in urine, with intra-individual variability attributed to variability in dietary Na intake and non-adherence with urine collection procedures. However, a recent report from a Russian space flight simulation documented unexpectedly high day-to-day variability in urine Na excretion on a fixed intake. Objective: To analyze daily urinary Na excretion from a balance study that was conducted in black and white girls on both low and high levels of dietary Na. Methods: Sodium balance was assessed in 22 black and 13 white adolescent girls, (11-15 y, BMI 15-29 kg/m 2 ) in a randomized, crossover design with controlled diets containing either low (57 mmol/d) or high (167 mmol/d) Na, each for three weeks. Participants collected all urine in acid washed containers. Urine was pooled as 24-h samples and analyzed for sodium by atomic absorption spectrophotometry and creatinine by automated colorimetric method. Coefficients of variation (CV) for urinary Na were calculated for each teen. A mixed model was used to describe the effects of dietary Na and race. Results: The figures below give an example of the Na variability of one black teen on both the high (left) and low (right) Na diets. The horizontal line represents the Na intake. The CV analysis indicated higher variation about the mean on low (vs high) Na (40% vs 32%, p=0.02) and in black (vs white) girls (42% vs 30%, p<0.001). There was no diet x race interaction. Excretion of 50 mmol/d or less was documented on 6.6% of the days during the high Na dietary period. Conclusions: The high intra-individual variability in urinary Na excretion on a fixed diet highlights the potential for substantial error in (a) using a single 24 hour urine collection to estimate usual Na intake and (b) relating Na excretion from a single 24 hour collection with outcomes.

Anorexia nervosa is an eating disorder causing people to obsess about weight and what they eat. It is a characterized by a distorted body image with a fear of overweight. This causes abnormally low body weight. People with anorexia has an intense fear of gaining weight and distorted perception of weight. It mainly of two types-
I) RESTRICTING- where person loses weight by severe limitation of food intake.
ii) BEINGE/PURINGING- in which there are periods of food intake that are compensated by self induced vomiting, laxative or diuretic abuse or excessive exercise.
Signs maybe behavioral or physical like obsessing about weight, weight gain fears, eating only low calorie food, bloated, constipated, irritable, distracted and not able to concentrate.
It is prevalent in young women and teenage girls. People consider anorexia nervosa in connection with females but it can affect people of any sex or gender. Master agreement is for intricate, broad, long haul medicines that utilization a comprehension of the brain Physiology, precise standards and methods acquired from persuasive support treatment and argumentative conduct treatment. These therapies ought to be acted in various settings that meet the degree of power and level of management and clinical consideration required. There is a need to arrange crafted by a wide scope of clinical and mental administrations which frequently don’t cooperate. Due to the age bunch included and the also time span included, patient consideration frequently goes through many changes. This is the pinnacle of backslide and decompensation.

Background: Menstruation is a biological event imbued with social, cultural and personal significance. Due to impact of social media and internet the incidence of indulging in unprotected sexual intercourse and unplanned pregnancies are rapidly increasing among teenagers. Objectives were to assess the knowledge regarding safe sex and contraceptive methods and compare the menstrual and sexual awareness among adolescent girls in rural and urban settings.Methods: The health questionnaire was prepared from WHO adolescent health manual as reference base. The adolescent survey was done.Results: In present study maximum number of girls had attained menarche between 12-15 years in both groups. The study showed lack of menstrual hygiene among rural girls in compare to urban girls where 79% girls use either sanitary pads or cotton and in comparison to urban girls, rural girls had more restrictions in going out.Conclusions: Education regarding proper physiology of menses and there should be open discussion regarding restrictions and taboos related to menses at the school level to minimise the false beliefs.

Research shows women with type 1 diabetes (T1D) face a disproportionately increased risk for development of cardiovascular disease (CVD) compared to men. We posit, adolescence may be a critical time period for CVD risk development. Our study examined the effects on gender differences in Hemoglobin A1c (HbA1c) and Body Mass Index z-score (BMIz) across puberty in children with T1D in a large pediatric diabetes specialty clinic. A total of 733 T1D children (M=355, F=378) aged 9-17 with a total of 21,534 visits from the Barbara Davis Center were suitable for this retrospective cohort study. To exam HbA1c and BMIz overtime by gender we used a linear mixed model with SAS version 9.4. HbA1c increased with age in both genders (p<0.0001), but there was a greater increase in girls across adolescence (sex by age interaction, p<0.0007). BMIz increased with age in girls only (sex by age interaction, p<0.0001). Teenagers had worse glycemic control than younger children, and girls had worse glycemic control with greater obesity rates than boys. This gender difference in glycemic control and obesity during puberty may explain the increased CVD risk seen in women with T1D compared to men.

Abstract Background Unintentional injuries among children and adolescents are a major public health problem worldwide. These injuries not only have negative effects on children’s physiology and psychology, but also bring huge economic losses and social burdens to families and society. Unintentional injuries are the leading cause of disability and death among Chinese adolescents, and left-behind children (LBC) are more prone to experience unintentional injury. The purpose of this study was to evaluate the type and incidence of unintentional injury among Chinese children and adolescents and explore the influences of personal and environmental factors by comparing the differences between LBC and not left-behind children (NLBC). Methods This cross-sectional study was conducted in January and February 2019. Additionally, 2786 children and adolescents from 10 to 19 years old in Liaoning Province in China were collected in the form of self-filled questionnaires, including Unintentional Injury Investigation, Unintentional Injury Perception Questionnaire, Multidimensional Subhealth Questionnaire of Adolescent (MSQA), Negative life events, “My Class” questionnaire and Bullying/victim Questionnaire. Multiple logistic regression analysis was used to explore the factors associated with unintentional injury among children and adolescents. Binary logistic regression analysis was used to explore the factors affecting unintentional injuries between LBC and NLBC. Results The top three unintentional injuries were falling injuries (29.7%), sprains (27.2%) and burns and scalds (20.3%) in our study population. The incidence of unintentional injuries in LBC was higher than that in NLBC. Burn and scalds, cutting injury and animal bites in LBC were higher than those in NLBC. The results show that junior high school students (odds ratio (OR) = 1.296, CI = 1.066–1.574) were more likely to report multiple unintentional injuries than primary school students. Girls (OR = 1.252, CI = 1.042–1.504) had higher odds of reporting multiple unintentional injuries. The odds of multiple injuries in children and adolescents with low levels of unintentional injury perception were higher than those in children and adolescents with high levels of unintentional injury perception (OR = 1.321, C = 1.013–1.568). Children and adolescents with a higher levels of mental health symptoms (OR = 1.442, CI = 1.193–1.744) had higher odds of reporting multiple unintentional injuries. Compared with teenagers who had never experienced negative life events, teenagers who had experienced negative life events many times (OR = 2.724, CI = 2.121–3.499) were more likely to suffer unintentional injuries many times. Low-level discipline and order (OR = 1.277, CI = 1.036–1.574) had higher odds of reporting multiple unintentional injuries. In-school adolescents who were bullied were more likely to report being injured multiple times than their counterparts who were not bullied (OR = 2.340, CI = 1.925–2.845). Low levels of unintentional injury perception, experienced negative life events and bullying had greater impacts on LBC than on NLBC. Conclusion The survey found that the incidence of at least one unintentional injury was 64.8%. School level, sex, unintentional injury perception, subhealth, negative life events, discipline and order and bullying were associated with incidents of unintentional injury. Compared with NLBC, LBC had a higher incidence of unintentional injury, and special attention should be given to this group.
