Abstract (sommario):

Most professional and international organizations recommend folic acid supplementation for women planning pregnancy. Various studies have shown high levels of non-compliance with this recommendation. This study aimed to identify sociodemographic characteristics related to this compliance. The analyses were based on 16,809 women from the French nationwide ELFE cohort (Etude Longitudinale Française depuis l’Enfance). Folic acid supplementation was assessed at delivery, and sociodemographic characteristics were collected at two months postpartum. The association between sociodemographic characteristics and compliance with recommendations on folic acid supplementation (no supplementation, periconceptional supplementation, and supplementation only after the periconceptional period) was examined using multivariate multinomial logistic regression. Only 26% of French women received folic acid supplementation during the periconceptional period, 10% of women received supplementation after the periconceptional period, and 64% received no supplementation. Young maternal age, low education level, low family income, multiparity, single parenthood, maternal unemployment, maternal overweight, and smoking during pregnancy were related to lower likelihood of folic acid supplementation during the periconceptional period compared to no supplementation. These associations were not explained by unplanned pregnancy. Immigrant and underweight women were more likely to receive folic acid supplementation after the periconceptional period. Our study confirms great social disparities in France regarding the compliance with the recommendations on folic acid supplementation.

Abstract (sommario):

This study aimed to characterize paternal diet during the peri-conception period and its associated characteristics. These cross-sectional analyses were based on 998 fathers from the French nationwide ELFE birth cohort recruited in 2011. Fathers’ diet before mothers’ pregnancies was assessed by a 46-item food frequency questionnaire. Six exploratory dietary patterns were identified by principal component analysis: “Diverse diet”, “Balanced”, “Alcohol”, “Snacking”, “Bread and cheese”, and “Processed products”. Older age was related to higher scores for the “Balanced”, “Alcohol”, and “Snacking” patterns, and high education level with high scores on the “Balanced” pattern and low scores on the “Processed products” pattern. Unemployment and having a first child were related to high scores on the “Alcohol” pattern. Smoking was positively related to “Alcohol” and “Processed products” patterns. A restrictive diet was associated with high scores on the “Balanced” and “Processed products” patterns and low scores on “Alcohol”, “Snacking”, and “Bread and cheese” patterns. Maternal dietary patterns, identified in a previous analysis, were moderately and positively related to the similar patterns among fathers. These findings are important for screening fathers at risk of a suboptimal diet and for accounting for this factor in future studies to examine the specific influence of paternal diet on a child’s health and development.

Abstract (sommario):

AbstractBackground:Pregnant women are vulnerable to the deleterious impact of environmental stressors. The aims were to identify the environmental and pregnancy characteristics independently associated with prenatal psychological distress and access to mental health care.Methods:We used data from the French cohort Étude Longitudinale Française depuis l’Enfance (ELFE), a nationally representative cohort of children followed-up from birth to adulthood. Information about prenatal psychological status and access to mental health care was collected during the maternity stay. Maternal/pregnancy characteristics independently associated with psychological distress and access to mental health care were explored using multivariate analyses.Results:Of the 15,143 mothers included, 12.6% reported prenatal psychological distress. Prenatal distress was more frequent in women with very low economical status, alcohol/tobacco use, unplanned/unwanted pregnancy, late pregnancy declaration, multiparity and complicated pregnancy (high number of prenatal visits, prenatal diagnosis examination, obstetrical complications). Of the women reporting prenatal distress, 25% had a prenatal consultation with a mental health specialist and 11% used psychotropic drugs during pregnancy. Decreased likelihood to consult a mental health specialist was found in young women, with intermediate educational level and born abroad.Limitations:Causal inferences should be made cautiously as the questionnaire did not collect information on the temporal sequence between psychological distress and associated characteristics.Conclusions:Women with social and obstetrical vulnerabilities are at increased risk of poor mental health during pregnancy. Improving mental health care access during pregnancy is a public health priority.

Abstract (sommario):

Objective: The risk factors for postnatal depressive symptoms (PNDS) are numerous, but little is known about the protective factors or the interactions between different exposures. The present study explored the pathways between maternal, infant and parenthood vulnerabilities or risk/protective factors and PNDS at 2 months postpartum (PP) in a large sample of women from the general population. Methods: We used data from the French ELFE cohort, a nationally representative cohort of children followed-up from birth. The available information about vulnerabilities or risk/protective factors for PNDS was collected during the maternity ward stay (mother or medical records) and at 2 months PP (mother by phone). PNDS were evaluated with the Edinburgh Postnatal Depression Scale (EPDS) at 2 months. A measurement model was built based on the psychosocial model for PNDS of Milgrom and colleagues using exploratory factor analysis. The Structural Equation Model was used to investigate the pathways between vulnerability, risk/protective factors and PNDS at 2 months PP. Results: In the study sample (n = 11,583), a lack of a partner’s perceived antenatal emotional support, consultation with a mental health specialist before pregnancy, family financial difficulties, prenatal psychological distress and a difficult pregnancy experience were directly associated with the severity of maternal PNDS at 2 months PP, as well as lack of perceived postnatal support. Family financial difficulties and consultation with a mental health specialist before pregnancy were also indirectly associated with the intensity of PNDS through a lack of perceived antenatal emotional support, a difficult pregnancy experience, prenatal psychological distress and a lack of perceived postnatal support. Regarding infant and parenthood characteristics, infant self-regulation difficulties, maternal difficulty in understanding infant crying and infant hospitalisation were directly associated with PNDS severity at 2 months PP, while maternal difficulty in understanding an infant’s cries was also indirectly associated with infant self-regulation difficulties. Conclusions: Perinatal professional support should begin antenatally and target the couple’s prenatal functioning, with particular attention to women presenting a history of psychiatric disorders, especially those of low socioeconomic status. After delivery, addressing infant and parenthood characteristics is also recommended.

Abstract (sommario):

IntroductionMany countries are currently expanding their paternity leave policies, which have positive effects on parental mental health.ObjectivesWe examined whether two weeks of paid paternity leave are associated with post-partum depression (PPD) in mothers and fathers at two months after the birth of their child.MethodsData originated from The Etude Longitudinale Française depuis l’Enfance (ELFE) cohort study. A total of 10 975 fathers and 13 075 mothers with reported information on paternity leave and PPD at two months were included in the statistical analyses. Logistic regression models, using survey-weighted data and adjusted for confounders using Inverse Probability Weights (IPW), yielded Odds Ratios.ResultsFathers had a median age of 32∙6 (inter-quartile range (IQR) 36∙9 – 22∙6 years), and mothers had a median age of 30∙5 years (IQR 34∙0 – 27∙1 years) at the time of the ELFE child’s birth. Fathers who took paternity leave had reduced odds of PPD [0∙74 (95% CI: 0∙70 -0∙78)] as well as fathers who intended to take paternity leave [0∙76 (95 CI%: 0∙70 – 0∙82)] compared to fathers who did not take paternity leave. Mothers had an increased likelihood of PPD at two months if their partners took paternity leave [1∙13 (95 CI%: 1∙05 – 1∙20)]. Fathers’ educational level, work contract type nor the number of children in the family were found to be interactions (p>0.25).ConclusionsTaking and intending to take a two-week paid paternity leave is associated with lower odds of PPD in fathers. Mothers whose partners take paternity leave experience borderline higher odds of PPD at two months. Offering only a two-week paternity leave may protect fathers against PPD but does not significantly protect may increase mothers’ risk of against PPD onset.Disclosure of InterestNone Declared

Abstract (sommario):

The assessment of early life socioeconomic position (SEP) is essential to the tackling of social inequalities in health. Although different indicators capture different SEP dimensions, maternal education is often used as the only indicator in birth cohort research, especially in multi-cohort analyses. Household income, as a direct measure of material resources, is one of the most important indicators, but one that is underused because it is difficult to measure through questionnaires. We propose a method to construct a standardized, cross-cohort comparable income indicator, the “Equivalized Household Income Indicator (EHII)”, which measures the equivalized disposable household income, using external data from the pan-European Union Statistics on Income and Living Conditions (EUSILC) surveys, and data from the cohorts. We apply this method to four studies, Piccolipiù and NINFEA from Italy and ELFE and EDEN from France, comparing the distribution of EHII with other SEP-related variables available in the cohorts, and estimating the association between EHII and child body mass index (BMI). We found that basic parental and household characteristics may be used, with a fairly good performance, to predict the household income. We observed a strong correlation between EHII and both the self-reported income, whenever available, and other individual socioeconomic-related variables, and an inverse association with child BMI. EHII could contribute to improving research on social inequalities in health, in particular in the context of European birth cohort collaborative studies.

Abstract (sommario):

Family characteristics such as education level or income are related to infant feeding practices. This study aimed to characterize infant feeding practices and investigate their associations with family characteristics. Analyses were performed with data from a French nationwide cohort, Etude Longitudinale Française depuis l’Enfance (ELFE). Feeding practices were characterized by two methods, a principal component analysis and a hierarchical ascendant classification (n = 8922). This characterization was conducted in three steps: considering firstly only introduction of main food groups, then also food pieces and finally adding the type of complementary food. The associations between family characteristics and the infant feeding patterns or clusters were tested by linear or multinomial regressions (n = 7556). Besides breastfeeding duration and age of first introduction of complementary foods, it appeared also important to consider specific food groups such as sweetened beverages and cow’s milk, and the introduction of food pieces, to describe feeding practices. Recommended feeding practices (longer breastfeeding, complementary food in the right period) were related to higher maternal age and education level, so was migration status, the presence of older children, low income or the mothers’ attendance to pre-birth preparation classes. The interrelations between feeding practices and family characteristics must be considered when examining the influence of feeding practices on child’s health.

Abstract (sommario):

Abstract Proponents of early childhood education and care programs cite evidence that high-quality center-based childcare has positive impacts on child development, particularly for disadvantaged children. However, much of this evidence stems from randomized evaluations of small-scale intensive programs based in the United States and other Anglo/English-speaking countries. Evidence is more mixed with respect to widespread or universal center-based childcare provision. In addition, most evidence is based on childcare experiences of 3- to 5-year-old children; less is known about the impact of center-based care in earlier childhood. The French context is particularly suited to such interrogation because the majority of French children who attend center-based care do so in high-quality, state-funded, state-regulated centers, known as crèches, and before age 3. We use data from a large, nationally representative French birth cohort, the Étude Longitudinale Français depuis l'Enfance (Elfe), and an instrumental variables strategy that leverages exogenous variation in both birth quarter and local crèche supply to estimate whether crèche attendance at age 1 has an impact on language, motor skills, and child behavior at age 2. Results indicate that crèche attendance has a positive impact on language skills, no impact on motor skills, and a negative impact on behavior. Moreover, the positive impact on language skills is particularly concentrated among disadvantaged children. This implies that facilitating increased crèche access among disadvantaged families may hold potential for decreasing early socioeconomic disparities in language development and, given the importance of early development for later-life outcomes, thereby have an impact on long-term population inequalities.

Abstract (sommario):

Background: In France, updated data on food allergies (FAs) are lacking, despite the need for efficient FA management and prevention. This study aimed to evaluate the prevalence of FAs in children in France, describe the most common allergens and determine the prevalence of atopic diseases in children with FAs. Methods: The ELFE study comprises a French nationwide birth cohort, including 18,329 children born in 2011. FAs were assessed by parental reports of food avoidance based on medical advice related to FAs, provided at 2 months and 2, 3.5 and 5.5 years of age. Data regarding FAs were available for 16,400 children. Data were weighted to account for selection and attrition bias. Results: From birth to 5.5 years of age, FAs were reported for 5.94% (95% CI: 5.54–6.34) children. Milk was the most common allergen, followed by egg, peanut, exotic fruits, tree nuts, gluten and fish. Among children with FAs, 20.5% had an allergy to at least two different groups of allergens; 71% reported eczema at least once before 5.5 years of age; 24.4% reported incidence of asthma; and 42.3% reported incidence of allergic rhinitis or conjunctivitis. Conclusion: In France, the prevalence of FAs in children up to 5.5 years of age is approximately 6%. It was demonstrated that 1 in 5 children with allergies had multiple FAs.

Abstract (sommario):

The French National Cohort of Children Study (Etude Longitudinale Française depuis l'Enfance—ELFE) tested the literacy and numeracy skills of 4- to 5-year-old typically developing children in the second year of école maternelle. Tasks were administered by more than 4,000 teachers at schools across France. One of the study's numeracy tasks required participants to write the number of ducks (up to 5) they had counted. Analyzing the digits written by 14,904 children showed that miswritings were much more common for the digit 3 than for the digit 4. This result is consistent with the right-orienting rule, which young children in Western cultures apply when they do not know a digit's orientation, and which leads them to write, for example, ε instead of 3.The nature and frequency of miswritten digits did not differ significantly between the 466 children presumed to have written with their left hand and the 3,531 children presumed to have written with their right hand. However, a logistic mixed-effects regression showed that two other factors—age of entry to école maternelle and very early smartphone use—had a (modest) influence on the percentage of digits that were miswritten.

Abstract (sommario):

Background: Studies have reported associations between maternal exposure to atmospheric pollution and lower birth weight. However, the evidence is not consistent and uncertainties remain. We used advanced statistical approaches to robustly estimate the association of atmospheric pollutant exposure during specific pregnancy time windows with term birth weight (TBW) in a nationwide study. Methods: Among 13,334 women from the French Longitudinal Study of Children (ELFE) cohort, exposures to PM2.5, PM10 (particles < 2.5 µm and <10 µm) and NO2 (nitrogen dioxide) were estimated using a fine spatio-temporal exposure model. We used inverse probability scores and doubly robust methods in generalized additive models accounting for spatial autocorrelation to study the association of such exposures with TBW. Results: First trimester exposures were associated with an increased TBW. Second trimester exposures were associated with a decreased TBW by 17.1 g (95% CI, −26.8, −7.3) and by 18.0 g (−26.6, −9.4) for each 5 µg/m3 increase in PM2.5 and PM10, respectively, and by 15.9 g (−27.6, −4.2) for each 10 µg/m3 increase in NO2. Third trimester exposures (truncated at 37 gestational weeks) were associated with a decreased TBW by 48.1 g (−58.1, −38.0) for PM2.5, 38.1 g (−46.7, −29.6) for PM10 and 14.7 g (−25.3, −4.0) for NO2. Effects of pollutants on TBW were larger in rural areas. Conclusions: Our results support an adverse effect of air pollutant exposure on TBW. We highlighted a larger effect of air pollutants on TBW among women living in rural areas compared to women living in urban areas.

Abstract (sommario):

Between June and December 2017, a protocol involving questionnaires designed to be enjoyable for children was implemented as part of the ELFE cohort study. This national study has followed 18,000 children since their birth in 2011. These sociological questionnaire/games aimed to collect information on the everyday preferences of young children (then aged 5-6 years old) and indicators of their moral and social sense. But this collection method had neither pre-existing experiments it could draw on, nor technology that had been fully perfected. This article revisits the methodological questions and issues that were raised over the process of developing and then administering these online questionnaires. In particular it looks at the way that social representations of childhood and research with children were raised in exchanges between sociologists and epidemiologists, or between researchers and parents.

Abstract (sommario):

Objective: This article explores the consequences of the first COVID-19 lockdown in the spring of 2020 in France on intra-family relationships and 9-year-old children's socio-emotional well-being. Background: On 17th March 2020, France began a strict lockdown to contain the COVID-19 pandemic, with school closures and limited outings permitted until early June. All family routines and work-life arrangements were impacted. A major concern relates to how these measures impacted family and child well-being. Method: We use data from the Elfe Sapris survey, administered during the first lockdown to about 5,000 families participating to the Etude longitudinale française depuis l'enfance (Elfe), a nationally representative birth cohort of children born in 2011. We analysed correlations between parents' socioeconomic and living conditions on four relational indicators: the experience of lockdown, the quality of relationships between parents and children, and between siblings, and an indicator of children’s socio-emotional well-being, the Strengths and Difficulties Questionnaire (SDQ). Results: The impact of the lockdown on family well-being was conditional on socio-economic factors and their changes over the period. Deterioration of households' financial situation and having to work outside the home during lockdown was negatively correlated with family relationships and children’s socio-emotional well-being. Conclusion: Overall, our results suggest that while France's first lockdown was a relatively positive period for many households with a primary-school-aged child, we highlight that restrictions exacerbated existing difficulties for disadvantaged families.

Abstract (sommario):

ObjectivesPrenatal occupational exposure to pesticides has been associated with male reproductive tract abnormalities. Little is known about the possible impact of non-occupational pesticide exposure on fetal and child development in the general population. Using data from a nationwide birth cohort, we aimed to assess the association between residential sources of prenatal pesticide exposure and the risks of hypospadias and cryptorchidism.MethodsOf the 9281 boys in ELFE (French Longitudinal Study of Children), the national French birth cohort, 53 were diagnosed with hypospadias and 137 with cryptorchidism. We assessed residential exposure sources from self-reported domestic use of eight types of pesticide products and French spatial land use data with acreage within a 1000 m radius around each family’s home for 21 crop types. We used logistic regression modelling, adjusted for possible confounders that included estimated dietary pesticide intake. Multiple imputations were used to handle missing data.ResultsAn increased risk of hypospadias was associated with domestic pesticide use against fleas and ticks (OR=2.28, 95% CI 1.09 to 4.75); no associations were found between cryptorchidism and any domestic pesticide use. Slightly increased risks of cryptorchidism were observed in association with all crop acreages near homes during pregnancy, especially for orchards, and no association was observed for hypospadias.ConclusionsOur results suggest a possible increased risk of hypospadias associated with prenatal use of some domestic pesticide products, likely to contain insecticides, and of cryptorchidism with nearby orchard acreage (crops repeatedly sprayed with pesticides). This work is limited by its modest number of cases.

Abstract (sommario):

Abstract Introduction There has been little focus on sleep and its relation to behavior and cognition in preschool-aged children. We aimed to investigate the association between sleep duration in early preschoolers (» 3.5 years of age) and later behavioral and cognitive outcomes (» 5 years of age) in European children. Methods We used harmonized data from five cohorts from the EU Child Cohort Network, established by the LifeCycle Project (n=16.444 children): ALSPAC and SWS from UK, EDEN and ELFE from France and INMA from Spain. Within all cohorts, total sleep duration per day and behavioral and cognitive information were reported by parents. Internalizing and externalizing behaviors were measured with the Strengths and Difficulties Questionnaire and treated as percentile scores. Verbal and non-verbal intelligence were assessed by the Wechsler Preschool and Primary Scale of Intelligence or with the McCarthy Scales of Children’s Abilities depending on the cohort and treated as standardized scores. All scores were cohort specific. Associations between sleep duration during early preschool age and later behavior and/or cognition were estimated using linear regression and pooled with two-stage individual participant data meta-analysis adjusted for child, maternal and household information. Analyses were done in DataSHIELD. Results Global mean sleep duration was 11h54 ± 1h00 per day at mean age 3.5 years but differed by country, with children from France showing longer sleep duration than children from the UK or Spain. In multivariate meta-analysis, 1 hour of additional sleep duration per day at mean age 3.5 years was associated with reduced internalizing and externalizing behavior percentile scores at mean age 5.1 years (internalizing behavior: badjusted= -1.05, 95%-CI [-1.93, -0.18], I2: 30.3%; externalizing behavior: badjusted= -2.12, 95%-CI [-2.78, -1.47], I2: 0.0%). No association was observed between sleep duration and subsequent verbal or non-verbal intelligence Conclusion Longer sleep duration in early preschool age (» 3.5 years of age) was associated with subsequent lower internalizing and externalizing behavior scores (» 5 years of age), but not with verbal or non-verbal intelligence. Adequate sleep duration at an early age is important for children’s later mental health. Support (If Any) KG was granted a LifeCycle fellowship.

Abstract (sommario):

Background: Insufficient social support has been intensively studied as a risk factor of postpartum depression (PPD) among mothers. However, to date, no study has examined the role of informal and formal dimensions of social support during pregnancy with regard to joint maternal and paternal depression after birth. Aim: Study associations between insufficient informal and formal support during pregnancy and joint parental PPD. Methods: Using data from the nationally representative French ELFE ( Etude Longitudinale Française depuis l’Enfance) cohort study ( N = 12,350), we estimated associations between insufficient informal and formal support received by the mother during pregnancy and joint parental PPD in multi-imputed multivariate multinomial regression models. Results: In 166 couples (1.3%), both parents were depressed. The likelihood of joint parental PPD was increased in case of insufficient informal support (insufficient partner support: odds ratio (OR) = 1.68 (95% confidence interval (CI): 1.57–1.80); frequent quarrels: OR = 1.38 (95% CI: 1.19–1.60)). We also observed associations between formal support during pregnancy and joint parental PPD (early prenatal psychosocial risk assessment: OR = 1.13 (95% CI: 1.05–1.22); antenatal education: OR = 1.13 (95% CI: 1.05–1.23)), which disappeared when analyses were restricted to women with no psychological difficulties during pregnancy. Conclusion: Insufficient informal social support during pregnancy appears to predict risk of joint PPD in mothers and fathers and should be identified early on to limit complications and the impact on children.

Abstract (sommario):

In low- and middle-income countries, the protective effect of breastfeeding against infections is well established, but in high-income countries, the effect could be weakened by higher hygienic conditions. We aimed to examine the association between breastfeeding and infections in the first 2 years of life, in a high-income country with relatively short breastfeeding duration. Among 10,349 young children from the nationwide Etude Longitudinale Française depuis l’Enfance (ELFE) birth cohort, breastfeeding and parent-reported hospitalizations, bronchiolitis and otitis events, and antibiotic use were prospectively collected up to 2 years. Never-breastfed infants were used as reference group. Any breastfeeding for <3 months was associated with higher risks of hospitalizations from gastrointestinal infections or fever. Predominant breastfeeding for <1 month was associated with higher risk of a single hospital admission while predominant breastfeeding for ≥3 months was associated with a lower risk of long duration (≥4 nights) of hospitalization. Ever breastfeeding was associated with lower risk of antibiotic use. This study confirmed the well-known associations between breastfeeding and hospitalizations but also highlighted a strong inverse association between breastfeeding and antibiotic use. Although we cannot infer causality from this observational study, this finding is worth highlighting in a context of rising concern regarding antibiotic resistance.

Abstract (sommario):

The consumption of sugar, salt, and fat in infancy may influence later health. The objective of this study was to describe the frequency of use of added sugar, salt, and fat during the complementary feeding period and the associated infant caregiving practices. Data were obtained from a monthly questionnaire filled by parents for 10,907 infants from the French Etude Longitudinale Française depuis l’Enfance (ELFE) cohort. A score of frequency of use (SU) for added sugar, salt, and fat (oil, margarine, butter, and/or cream) was calculated from the age at complementary feeding introduction (CFI) to the 10th month. Associations between the SU of each added ingredient with infant feeding and caregiving practices were studied with multivariable linear regressions adjusted for familial characteristics. Only 28% of the parents followed the recommendation of adding fat and simultaneously not adding sugar or salt. Breastfeeding mothers were more prone to add sugar, salt, and fat than non-breastfeeding mothers. CFI before four months was positively associated with the SU of added sugar and salt and negatively associated with the SU of added fat. The use of commercial baby food was negatively related to the SU of added salt and fat. The use of these added ingredients was mainly related to breastfeeding, age at CFI, and use of commercial food, and it was independent of the household socioeconomic characteristics.
