Exploring the socioeconomic disparities of maternal body mass index: a national study in France.

BACKGROUND: The prevalence of overweight and obesity has increased in various countries. Normal weight before pregnancy is important to protect maternal and newborn health. This study aimed to describe the evolution of body mass index (BMI) before pregnancy in France and explore its association with two measures of socioeconomic status (SES), education and household income. METHODS: Data were from four national perinatal surveys in France in 1998, 2003, 2010 and 2016 to describe the time evolution of maternal BMI. We explored the links between BMI and women's characteristics in the most recent period (2010-2016 surveys) since income information was not available before. Risk ratios (RRs) of underweight, overweight and obesity for each measure of SES were computed by using multivariable Poisson regression models. RESULTS: Overweight and obesity prevalence increased between 1998 and 2016, from 6% to 12% for obesity. Both were inversely associated with SES (higher prevalence among least educated and poorest women), with strong variations for each social indicator, even in multivariable analyses including both. Combining education and income revealed a wide gradient; RR for obesity was 6.01 (95% confidence interval 4.89-7.38) with low education and income <2000 euros/month vs. high education and income ≥4000 euros/month. CONCLUSIONS: Public policies must implement programs to limit the increase in overweight and its unequal distribution in the population, alongside other policies to address the societal determinants of the obesogenic environment. Health professionals need to advise women to improve their eating and physical activity to limit weight gain from childhood to early adulthood.

The Impact of Maternal Depression and Parent-Child Interactions on Risk of Parasitic Infections in Early Childhood: A Prospective Cohort in Benin.

OBJECTIVES: Maternal depression occurs in 13-20% of women from low-income countries, which is associated with negative child health outcomes, including diarrheal disease. However, few studies have investigated its impact on child risk of infectious disease. We studied the impacts of maternal depressive symptoms and parent-child interactions, independently, on the risk of Plasmodium falciparum malaria and soil-transmitted helminth infection in Beninese children. METHODS: Our population included mothers and children enrolled in a clinical trial during pregnancy (MiPPAD) in Benin. The Edinburgh Postnatal Depression Scale (EPDS) assessed maternal depressive symptoms and the home observation measurement of the environment (HOME) assessed parent-child interactions. Blood and stool sample analyses diagnosed child malaria and helminth infection at 12, 18, and 24 months. Negative binomial and Poisson regression models with robust variance tested associations. RESULTS: Of the 302 mother-child pairs, 39 (12.9%) mothers had depressive symptoms. Median number of malaria episodes per child was 3 (0-14) and 29.1% children had at least one helminth infection. Higher EPDS scores were associated with lower HOME scores; relative risk (RR) 0.97 (95% confidence interval (CI) 0.95, 0.99), particularly with lower acceptance, involvement, and variety subscales; RR 0.92 (95% CI 0.85, 0.99), RR 0.82 (95% CI 0.77, 0.88), RR 0.93 (95% CI 0.88, 0.99), respectively. However, neither exposure was associated with risk of parasitic infection in children. CONCLUSIONS FOR PRACTICE: Maternal depressive symptoms are associated with poor parent-child interactions, particularly acceptance of behavior, involvement with children, and variety of interactions, but these exposures do not independently impact risk of parasitic infection in children.

Psychological symptoms and intensity of partner violence: A study of women attending an anti-violence center in Italy.

Intimate partner violence (IPV) can seriously affect the health of victims. Our aims were to analyze the impact of IPV intensity on psychological symptoms in a sample of 151 victimized women (21-74 years old). We collected data through anonymous-auto-administrated questionnaires from a sample of women attending five Anti-violence centers in Italy, and assessed exposure to psychological, physical, sexual, verbal, and stalking partner violence in the last year. We used multiple logistic regression analysis to examine the probability of reporting psychological symptoms associated with IPV. After controlling for the potential confounders, the increase in the intensity of violence was associated with an increase in reported nightmares, panic attacks, and auditory hallucinations, with a dose-response effect. We think that understanding the impact of IPV on women's mental health is necessary to improve their psychological well-being, support their path to liberation, and prevent chronic and more serious suffering.

L'impact de la COVID-19 sur la santé des enfants, groupe « protégé ¼ de l'infection.

OBJECTIVE: This article underlines that a viral epidemic and strategies to deal with it 1) have a major impact on groups that are a priori spared by the disease itself, in this case children, and 2) can generate health problems beyond the disease and lead to major social, economic and educational difficulties and an increase of social inequalities in health. METHOD: The observations presented are based on the scientific literature available in the first half of 2020 and on discussions with actors in the field, experts and heads of institutions, conducted by a working group of the Haut Conseil de la Santé Publique reflecting on a global and concerted policy for children's health. RESULTS: The health crisis and its management have had an impact on children's development and their quality of life. They have been more exposed to sedentary lifestyles, screens, accidents, and violence at home. The closure of schools and leisure facilities has led to difficulties in school, socialization, psychological well-being and mental health. Curative or preventive care has been postponed. These effects occurred with significant social and territorial inequalities. CONCLUSION: Any health crisis management requires an assessment of the overall impact of the epidemic and the proposed measures on health, economic, social, and educational indicators. This crisis shows the need for a coordinated children's policy, which is not currently the case in France.

Use of labour neuraxial analgesia according to maternal immigration status: a national cross-sectional retrospective population-based study in France.

BACKGROUND: Disparities in neuraxial analgesia use for childbirth by maternal origin have been reported in high-resource countries. We explored the association between maternal immigrant status (characterised separately by geographic continental origin and Human Development Index [HDI] of maternal country of birth) and neuraxial analgesia use. We hypothesised that immigrant women from low-resource countries may have more limited access to neuraxial analgesia than native French women. METHODS: The study population, extracted from the 2016 National Perinatal Survey, a cross-sectional study of a representative sample of births in France, included only women who initially wished to deliver with neuraxial analgesia. We used multivariable multilevel logistic regression to explore the association between immigrant status and both use of neuraxial analgesia and its timely administration. RESULTS: Among the 6070 women included, 88.1% gave birth with neuraxial analgesia and 15.8% were immigrants. There was no difference in neuraxial analgesia use between native French women and either immigrant women by geographic continental region of origin, or immigrants from countries with low HDI. However, immigrants from countries with very high HDI were more likely to give birth with neuraxial analgesia (adjusted odds ratio [aOR]=2.6; 95% confidence interval (CI), 1.2-5.8; P=0.018) and its timeliness <60 min after admission (aOR=1.8; 95% CI, 1.2-2.7; P=0.005) compared with native French women. CONCLUSIONS: In France, immigrant women from low-resource countries have similar access to labour neuraxial analgesia to native French women. Our results suggest differential neuraxial analgesia use in favour of immigrant women from very high HDI countries compared with native women.

Does women's place of birth affect their opportunity for an informed choice about Down syndrome screening? A population-based study in France.

BACKGROUND: To examine disparities by maternal place of birth in the opportunity to make an informed choice about Down syndrome screening, in France, where the national guidelines recommend that physicians offer it to all pregnant women. METHODS: We used population-based data from the nationally representative French Perinatal Surveys in 2010 and 2016 (N=24,644 women) to analyze the opportunity for an informed choice for prenatal screening, measured by a composite indicator. RESULTS: Among the 24 644 women in the study, 20 612 (83.6%) were born in France, 861 (3.5%) elsewhere in Europe, 1550 (6.3%) in North Africa, and 960 (3.9%) in sub-Saharan Africa. The probability of screening was lower for women born outside France. After adjustment for survey year, maternal age, parity, education level, and the maternity unit's level of perinatal care, women born outside France had the opportunity to make an informed choice less often than women born in France. This association remained essentially the same even after excluding women without adequate prenatal care. CONCLUSIONS: Women born outside France, including those with adequate prenatal care, had less opportunity than women born in France to make an informed choice about prenatal screening for Down syndrome.

Witnessing interparental violence in childhood and symptoms of depression in adulthood: data from the 2017 French Health Barometer.

BACKGROUND: Every year, it is estimated that 143 000 French children are exposed to interparental violence (IPV). This exposure may have deleterious lifelong impact on mental health. OBJECTIVE: To investigate the associations between exposure to IPV in childhood and, as adults, the presence of depressive symptoms during the past year, suicidal thoughts and lifetime suicide attempt. METHODS: Our study is based on data from the 2017 French Health Barometer, a general population cross-sectional phone survey. 25 319 adults living in Metropolitan France responded. Data were weighted to obtain a representative sample of the French population. Associations between childhood exposure to IPV and each of three outcomes in adulthood-symptoms of depression, suicidal ideation in the past year and lifetime suicide attempt-were studied by calculating odds ratios (ORs) and their 95% confidence intervals (CIs), stratifying by sex and using multivariate models (logistic regression). RESULTS: After adjustment for age, social variables, negative life events in childhood and lifetime history of sexual violence, reporting witnessed IPV is significantly associated with the presence of symptoms of depression during the past 12 months (aORmen = 1.88, 95% CI = 1.49-2.38, and aORwomen = 2.00, 1.72-2.32), suicidal thoughts in the past 12 months (aORmen = 1.97, 1.48-2.64, and aORwomen = 2.35, 1.89-2.93), and at least one lifetime suicide attempt (aORmen =2.39, 1.83-3.11 and aORwomen = 2.66, 2.25-3.16). CONCLUSION: Associations shown between a history of exposure to IPV and three mental health indicators in adulthood underline the need to study the lifelong impact of IPV.

Repeat induced abortion and adverse childhood experiences in Aquitaine, France: a cross-sectional survey.

OBJECTIVE: The aim of the study was to analyse the relationship between adverse childhood experiences (ACEs) and repeat induced abortion, with regard to the potential effects of social deprivation and intimate partner violence. METHODS: An observational cross-sectional survey was conducted across each of the 25 abortion centres in Aquitaine, France, from 15 June to 15 September 2009. The sample comprised 806 women >18 years who had requested an induced abortion. Data were collected through a self-reported anonymous questionnaire on ACEs and experience of previous abortion. The main outcome measure was the percentage of repeat induced abortions. RESULTS: Among the participants, 473 (58.7%) were having their first induced abortion and 333 (41.3%) had already had a previous induced abortion. The abortion rank (first, second, third or more) was inversely related to the proportion of women with no ACE exposure (28%, 20% and 9%, respectively) and positively related to the proportion of women with a high ACE exposure (17%, 27% and 32%, respectively). Compared with women with no ACE exposure who were having a first induced abortion, in those with high ACE exposure, the odds of a third or more request for abortion was high: adjusted odds ratio 7.73 (95% confidence interval 3.56, 16.77). CONCLUSION: We found a strong graded link between the extent of ACE exposure and the occurrence of repeat induced abortion.

Maternal employment and socio-economic status of families raising children born very preterm with motor or cognitive impairments: the EPIPAGE cohort study.

AIM: To describe maternal employment and the socio-economic status of the household up to 8 years after the very preterm birth of a child, according to the presence and type of motor or cognitive impairment. METHOD: A total of 1885 families from the French EPIPAGE cohort of children who were born very preterm between 1997 and 1998 were included. Motor and cognitive impairments were identified in children between the ages of 2 and 8 years in 770 families and were classified according to type. The 1115 families with children born very preterm without these impairments were considered the reference group. RESULTS: Mothers of children with severe motor or cognitive impairments were less often working at 5 years after the birth than the reference mothers (21% and 30% vs 57%; p<0.001). Those working before birth returned to work less often and those not working started to work less often after the birth than did reference mothers. At 8 years, mothers of children with severe impairments reported financial difficulties more often than mothers of children without impairments. INTERPRETATION: Despite a fairly protective regulatory framework in France, families of infants born very preterm with severe motor or cognitive impairments are socially underprivileged. Measures to maintain an acceptable standard of living for these families and their children are needed.

La santé des enfants en France : un enjeu négligé ?

INTRODUCTION: As part of the National Health Strategy, the High Council for Public Health (HCSP) was tasked with leading a reflection on a “comprehensive and concerted child health policy”. Policy-making requires relevant knowledge and statistical benchmarks. It therefore seemed useful to examine the French statistical system and active research topics. This assessment is expected to provide a current portrait of the priorities and implicit health choices for the children. It also aims to reveal insufficiently explored aspects of children’s health. METHODS: The inventory of this system was carried out on the basis of several methods, hearings, work of two documentalists, and analysis of the published and grey literature. RESULTS: The emphasis is on pathologies, medical prevention and behaviors conceived primarily as individual. The idea that the health of tomorrow’s adults is built up behind this apparent good health and its inequalities does not appear, or only marginally. The elements on affective, cognitive or relational development are not sufficiently analyzed, for lack of data. The living conditions of children, especially poverty and violence in all its forms, are not sufficiently considered as health issues. Research is developing today with a hospital-centric vision, without a real strategy of research on children’s health. DISCUSSION: Given the dispersion of data, publishing a summary report on children’s health on a regular basis is essential, as enriching the system with data on the environment, poverty and psychomotor, psychosocial and cognitive development. There is an urgent need to develop research on children’s health and to define a research strategy that does not exist today.

Mental distress and sexual harassment in Italian university students.

Only a few studies have analyzed the association between sexual harassment (SH) and mental health controlling for other types of violence. The aim of this study was to describe SH among male and female university students and analyze the association between harassment and mental distress controlling for sexual violence. An observational survey was conducted at Trieste University (Italy). Students answered an anonymous questionnaire about harassment that included three domains-sexual harassment, gender harassment, cyber harassment-and three psychological health indicators. The global harassment index was computed, with three levels: 0, no harassment; level 1, harassment in at least one of the three domains; and level 2, harassment in two or three domains. The symptoms of mental distress were measured by the 12-item General Health Questionnaire (GHQ) for depressive symptoms; a question about panic symptoms; and a question about general health. The sample included 759 students (412 women; 18 to 29 years old). After adjustment for age, birth country, couple relationship, employment status, mother's education, and previous sexual violence, the risk of mental distress was increased with harassment exposure. Men were affected in perceived health and depressive symptoms (GHQ score ≥ 6); women were affected in panic symptoms. Harassment has a strong negative impact on the mental health of victims; in some cases, men may be more affected than women. Clinicians should be aware of the negative impact of SH also on men.

Physical Violence During Pregnancy in France: Frequency and Impact on the Health of Expectant Mothers and New-Borns.

Objectives Even during pregnancy women may suffer from violence. We estimated the prevalence of physical abuse during pregnancy, we analyzed the main risk factors and described the relationship between physical violence, psychological wellbeing and pregnancy outcome. Methods We used a national representative sample of births, in all public and private maternity units, in 2016 in France. Women were interviewed after delivery, on their living conditions and occurrence of physical violence at least once during pregnancy. The study of risk factors and pregnancy outcome was done with multivariable logistic regressions. Results Of 12,330 women included in the analysis 1.8% (95% CI 1.6-2.0) had been exposed to physical violence during pregnancy. Risk of violence was associated with the couple situation [women without a partner or in couple not cohabiting (OR 2.89, 95% CI 1.96-4.26)], household income (less than 3000 euros monthly), and state medical assistance coverage. Physical violence was more prevalent in case of a history of induced abortion or cannabis use during pregnancy. Psychological distress was more frequent with than without physical violence (e.g., 62% vs. 24% had a sadness period during pregnancy, p < 0.001). The risk of spontaneous preterm birth and transfer of the newborn to a neonatal intensive care unit were significantly higher among women experiencing physical violence during pregnancy compared to other women. Conclusions for Practice Main factors associated with increased risk of violence during pregnancy were socio-economics. The identification by caregivers of women exposed to violence during pregnancy needs to be improved to develop preventive and care strategies.

Persistent maternal depressive symptoms trajectories influence children's IQ: The EDEN mother-child cohort.

BACKGROUND: This study assessed the association between timing and course of maternal depression from pregnancy onwards and children's cognitive development at ages 5 to 6. Potential interaction effects with child sex and family socioeconomic status were explored. METHODS: One thousand thirty-nine mother-child pairs from the French EDEN mother-child birth cohort were followed from 24 to 28 weeks of pregnancy onwards. Based on Center for Epidemiological Studies Depression (CES-D) and Edinburgh Postnatal Depression Scale (EPDS) scores assessed at six timepoints, longitudinal maternal depressive symptom trajectories were calculated with a group-based semiparametric method. Children's cognitive function was assessed at ages 5 to 6 by trained interviewers with the Wechsler Preschool and Primary Scale of Intelligence Third Edition (WPPSI-III), resulting in three composite scores: Verbal IQ (VIQ), Performance IQ (PIQ), and Full-Scale IQ (FSIQ). RESULTS: Five trajectories of maternal symptoms of depression could be distinguished: no symptoms, persistent intermediate-level depressive symptoms, persistent high depressive symptoms, high symptoms in pregnancy only, and high symptoms in the child's preschool period only. Multiple linear regression analyses showed that, compared to children of mothers who were never depressed, children of mothers with persistent high levels of depressive symptoms had reduced VIQ, PIQ, and FSIQ scores. This association was moderated by the child's sex, boys appearing especially vulnerable in case of persistent maternal depression. CONCLUSIONS: Chronicity of maternal depression predicts children's cognitive development at school entry age, particularly in boys. As maternal mental health is an early modifiable influence on child development, addressing the treatment needs of depressed mothers may help reduce the associated burden on the next generation.

Mother's education and offspring asthma risk in 10 European cohort studies.

Highly prevalent and typically beginning in childhood, asthma is a burdensome disease, yet the risk factors for this condition are not clarified. To enhance understanding, this study assessed the cohort-specific and pooled risk of maternal education on asthma in children aged 3-8 across 10 European countries. Data on 47,099 children were obtained from prospective birth cohort studies across 10 European countries. We calculated cohort-specific prevalence difference in asthma outcomes using the relative index of inequality (RII) and slope index of inequality (SII). Results from all countries were pooled using random-effects meta-analysis procedures to obtain mean RII and SII scores at the European level. Final models were adjusted for child sex, smoking during pregnancy, parity, mother's age and ethnicity. The higher the score the greater the magnitude of relative (RII, reference 1) and absolute (SII, reference 0) inequity. The pooled RII estimate for asthma risk across all cohorts was 1.46 (95% CI 1.26, 1.71) and the pooled SII estimate was 1.90 (95% CI 0.26, 3.54). Of the countries examined, France, the United Kingdom and the Netherlands had the highest prevalence's of childhood asthma and the largest inequity in asthma risk. Smaller inverse associations were noted for all other countries except Italy, which presented contradictory scores, but with small effect sizes. Tests for heterogeneity yielded significant results for SII scores. Overall, offspring of mothers with a low level of education had an increased relative and absolute risk of asthma compared to offspring of high-educated mothers.

Impact of Low Maternal Education on Early Childhood Overweight and Obesity in Europe.

BACKGROUND: Comparable evidence on adiposity inequalities in early life is lacking across a range of European countries. This study investigates whether low maternal education is associated with overweight and obesity risk in children from distinct European settings during early childhood. METHODS: Prospective data of 45 413 children from 11 European cohorts were used. Children's height and weight obtained at ages 4-7 years were used to assess prevalent overweight and obesity according to the International Obesity Task Force definition. The Relative/Slope Indices of Inequality (RII/SII) were estimated within each cohort and by gender to investigate adiposity risk among children born to mothers with low education as compared to counterparts born to mothers with high education. Individual-data meta-analyses were conducted to obtain aggregate estimates and to assess heterogeneity between cohorts. RESULTS: Low maternal education yielded a substantial risk of early childhood adiposity across 11 European countries. Low maternal education yielded a mean risk ratio of 1.58 (95% confidence interval (CI) 1.34, 1.85) and a mean risk difference of 7.78% (5.34, 10.22) in early childhood overweight, respectively, measured by the RII and SII. Early childhood obesity risk by low maternal education was as substantial for all cohorts combined (RII = 2.61 (2.10, 3.23)) and (SII = 4.01% (3.14, 4.88)). Inequalities in early childhood adiposity were consistent among boys, but varied among girls in a few cohorts. CONCLUSIONS: Considerable inequalities in overweight and obesity are evident among European children in early life. Tackling early childhood adiposity is necessary to promote children's immediate health and well-being and throughout the life course.

Occupational, social and medical characteristics of early prenatal leave in France.

BACKGROUND: In France, most women of childbearing age work. The prenatal leave law in France protects women during pregnancy and their employment. We aimed to describe how long before delivery women stopped working and analyse the association between occupational, social and medical factors and early prenatal leave (before 24 weeks' gestation). METHODS: The sample was extracted from the 2010 French National Perinatal Survey. Women were interviewed in French maternity units during a 1-week period. We focused on all women with a singleton live birth who were working during pregnancy (n = 10 149). Women were interviewed between delivery and discharge to collect information on employment, date of leave, sociodemographic and medical characteristics. RESULTS: Among women who worked during pregnancy, 27.5% reported early occupational leave (before 24 weeks' gestation). Early occupational leave was more frequent among women with unstable jobs (fixed-term vs. non-fixed-term contract: adjusted odds ratio aOR = 1.60 [95% confidence interval 1.40-1.84]) and with less-qualified occupational categories (manual workers vs. managers and upper-intellectual positions: aOR = 2.96 [2.30-3.82]), even after adjusting for sociodemographic and other employment characteristics. Women with a pathological or at risk pregnancy left work earlier than other women. After stratification on type of pregnancy there was still a higher rate of early leave for women with less qualified occupational group. CONCLUSION: In France, social vulnerability of pregnant women, linked to low sociodemographic situation or low occupational categories, is associated with early leave during pregnancy, even after stratification on type of pregnancy.

Who are the Women Who Work in Their Last Month of Pregnancy? Social and Occupational Characteristics and Birth Outcomes of Women Working Until the Last Month of Pregnancy in France.

Introduction The prenatal leave law in France protects women during pregnancy and their employment. We aimed to estimate the proportion of women who worked late in their pregnancy, to analyze the occupational, social and medical factors associated with late prenatal leave and to compare the pregnancy outcome of these women and those who left earlier in the pregnancy. Methods The sample was extracted from the 2010 French National Perinatal Survey. All women who delivered within a 1-week period were interviewed before discharge from the maternity unit. Women with a singleton live birth at or after 37 weeks' gestation and who were working during pregnancy (n = 8463) were included. Data were collected on employment, date of leave, and sociodemographic and medical characteristics. Results Overall, 328 women (3.9 %) took a late prenatal leave (at or after 37 weeks' gestation). Women who left late were older than 30 years old, with a high educational level and were living in an urban area. Being self-employed and having a managerial or upper-intellectual occupation was highly associated with late leave, before and after controlling for relevant variables. Perinatal and delivery outcomes were similar for women who took a late leave and those who left before 37 weeks' gestation. Discussion Occupational characteristics are the main determinants of late prenatal leave. Women working in the last month of pregnancy had a favorable social and occupational situation and did not did not experience an adverse pregnancy or birth outcome. Other studies are needed to understand the reasons for late leave and evaluate the post-partum fatigue and health of these women.

Maternal Depression Trajectories and Children's Behavior at Age 5 Years.

OBJECTIVE: To assess the relationship between trajectories of maternal depression from pregnancy to the child's age of 5 years and children's emotional and behavioral difficulties at age 5 years. STUDY DESIGN: Mother-child pairs (n = 1183) from the EDEN mother-child birth cohort study based in France were followed from 24 to 28 weeks of pregnancy to the child's fifth birthday. Children's behavior at age 5 years was assessed with the Strengths and Difficulties Questionnaire. Maternal depression was assessed repeatedly with the Center for Epidemiological Studies Depression questionnaire (pregnancy, 3, and 5 years of age) and the Edinburgh Postnatal Depression Scale (4, 8, and 12 months postpartum). Homogeneous latent trajectory groups of maternal depression were identified within the study population and correlated with Strengths and Difficulties Questionnaire scores by the use of multivariate linear regression analyzes. RESULTS: Five trajectories of maternal symptoms of depression were identified: no symptoms (62.0%); persistent intermediate-level depressive symptoms (25.3%); persistent high depressive symptoms (4.6%); high symptoms in pregnancy only (3.6%); and high symptoms in the child's preschool period only (4.6%). Children whose mothers had persistent depressive symptoms--either intermediate or high--had the greatest levels of emotional and behavioral difficulties at age 5 years. In addition, compared with children whose mothers were never depressed, those whose mothers had high symptoms in the preschool period also had increased levels of emotional symptoms, conduct problems, and peer problems. CONCLUSIONS: Maternal depression symptoms are related to children's emotional and behavioral problems, particularly if they are persistent (29.9%) or occur during early childhood (4.6%).

Multidimensionality of the relationship between social status and dietary patterns in early childhood: longitudinal results from the French EDEN mother-child cohort.

BACKGROUND: The association between socioeconomic position and diet in early childhood has mainly been addressed based on maternal education and household income. We aimed to assess the influence of a variety of social factors from different socio-ecological levels (parents, household and child-care) on multi-time point dietary patterns identified from 2 to 5 y. METHOD: This study included 974 children from the French EDEN mother-child cohort. Two multi-time point dietary patterns were derived in a previous study: they correspond to consistent exposures to either core- or non-core foods across 2, 3 and 5 y and were labelled "Guidelines" and "Processed, fast-foods". The associations of various social factors collected during pregnancy (age, education level) or at 2-y follow-up (mother's single status, occupation, work commitments, household financial disadvantage, presence of older siblings and child-care arrangements) with each of the two dietary patterns, were assessed by multivariable linear regression analysis. RESULTS: The adherence to a diet close to "Guidelines" was positively and independently associated with both maternal and paternal education levels. The adherence to a diet consistently composed of processed and fast-foods was essentially linked with maternal variables (younger age and lower education level), household financial disadvantage, the presence of older sibling (s) and being cared for at home by someone other than the mother. CONCLUSIONS: Multiple social factors operating at different levels (parents, household, and child-care) were found to be associated with the diet of young children. Different independent predictors were found for each of the two longitudinal dietary patterns, suggesting distinct pathways of influence. Our findings further suggest that interventions promoting healthier dietary choices for young children should involve both parents and take into account not only household financial disadvantage but also maternal age, family size and options for child-care.

Social context of preterm delivery in France in 2011 and impact on short-term health outcomes: the EPIPAGE 2 cohort study.

BACKGROUND: Low socio-economic context increases the risk of preterm delivery and may affect short-term outcomes in children born preterm. We described the social context of preterm delivery in France in 2011 and compared it with the general population of deliveries over the same period. We also studied how social context influenced pregnancy and delivery characteristics in the preterm population, and how it affected mortality and short-term morbidity in liveborn preterm children (<35 weeks). METHODS: We created an individual socio-economic vulnerability index, derived from multiple correspondence analysis based on maternal social information in the French National Perinatal Survey (NPS-2010). Weighted coordinates were applied to families from the EPIPAGE 2 study, a population-based cohort of preterm infants born in 2011, to quantify the infant's exposure to socio-economic vulnerability. Multivariable logistic models were used to relate the socio-economic context to pregnancy and delivery characteristics, and to assess its impact on short-term outcomes of the infants. RESULTS: Among mothers of preterm infants, gestational age decreased as socio-economic conditions worsened. In the most deprived group, women had more irregular pregnancy care, a higher prevalence of infection during pregnancy, and a lower rate of antenatal corticosteroid administration. The most deprived group was associated with a higher risk of severe morbidity for the preterm neonates. CONCLUSION: Our results emphasise the need for a large population-based surveillance system to identify the most deprived mothers, and to propose appropriate follow-up and care to these women and their infants in order to enhance long-term health.
