Background: Studies conducted on mild intellectual disability (MID) in children are infrequent and the prevalence rates vary widely. This study aimed to estimate the prevalence of MID in children in a French county (Isère), to describe the clinical signs and associated comorbidities, and to specify the aetiologies of this disability. Methods: The target population was comprised of the 15?100 children born in 1997 residing in Isère County, France, in 2008. Our goal was to find the children in this group with MID diagnosed between 9 and 13 years of age. MID was defined as an overall IQ score of between 50 and 69 [International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10)]; this definition was adjusted for the study by integrating confidence intervals so that the risk of IQ measurement relativity and possible discrepancy of scores could be taken into account. Children were identified through an administrative data source designed to assist disabled persons that contains health information, and an educational data source. Parents who agreed to let their children participate responded to an in-depth questionnaire on their child's medical and academic history. A genetic investigation was proposed for those children whose MID had an unknown aetiology. Results: The preliminary selection included 267 children, resulting in a prevalence rate of 18 per 1000 (CI [15.6; 19.9]), within the expected mean. Of these 267 cases, 181 families agreed to participate in the study (68%). MID more often affected boys [male gender ratio?=?1.4 (CI [1.2; 1.6])], low socioeconomic groups, and families with a history of intellectual disability. The clinical signs and comorbidities associated with MID were very frequent, with 54% spoken language disorders and 10% pervasive developmental disorder. Only 9% of the children had undergone a genetic investigation before the study. The known aetiology rate for MID was 19% among all the children who had had genetic tests performed. Conclusion: MID is an important public health issue based on its prevalence. The associated clinical signs and comorbidities may be warning signs of MID in case of learning difficulties. This study may help decision-makers to develop and organise screening and care for MID.

Objective: To estimate the prevalence of flatus-only and faecal incontinence, to describe their risk factors and to analyse the association between anal incontinence and psychological distress over the first year postpartum.Design: Cohort study from pregnancy to 12 months postpartum.Setting: Two university hospital maternity wards in France.Population: A total of 2002 pregnant women were recruited between 2003 and 2006. Data on anal incontinence were available for the 1632 women who comprise the sample for analysis.Methods: Women were enrolled during pregnancy. A postal questionnaire was sent at 4 and 12 months postpartum.Main Outcome Measures: Anal (flatus-only and faecal) incontinence was assessed at 4 months postpartum. Mental health was assessed at 4 and 12 months postpartum by the Edinburgh Postpartum Depression Scale (EPDS) and use of antidepressant drugs as well as by self-rated mental health.Results: At 4 months postpartum, the prevalence for flatus-only incontinence was 14.4% and for faecal incontinence 1.7%; multivariate analysis, restricted to women reporting no anal incontinence before the index pregnancy, showed that continuing breastfeeding at 4 months was related to a higher risk of de novo postpartum anal incontinence (OR = 2.23). Women who reported anal incontinence at 4 months were more frequently depressed (EPDS ≥10 or antidepressant use) at 12 months postpartum: 36.0% of those with faecal incontinence were depressed, 23.3% of those with flatus-only incontinence and only 14.8% of the continent women.Conclusion: Postnatal faecal incontinence was rare but associated with poorer maternal mental health. Postnatal screening should be encouraged, and psychological support offered.Tweetable Abstract: Postnatal faecal incontinence was associated with depression; postnatal screening should be encouraged and psychological support offered.

OBJECTIVE: The purpose of this study was to examine the relationships between different causes of preterm delivery (eg, maternal hypertension, small-for-gestational age [SGA], other) and cerebral damage (eg, cystic periventricular leukomalacia [c-PVL], grade III intraventricular hemorrhage [IVH], and intra-parenchymal hemorrhage [IPH]). STUDY DESIGN: This study included 1902 very preterm singletons who were transferred to neonatal intensive care units in 9 French regions. We used logistic regression models to compare the risk of cerebral injury associated with maternal hypertension, SGA, and all other causes of preterm delivery. RESULTS: We found that the risk of c-PVL and grade III IVH was higher in infants born after preterm premature rupture of membranes (PPROM) with short latency or idiopathic preterm labor than in infants born to hypertensive mothers. We show that SGA and antepartum maternal hemorrhage significantly increase the risk of IPH. CONCLUSION: Our results show that infants born to hypertensive mothers have a lower risk of cerebral injuries than infants born following idiopathic preterm labor and PPROM because they are less exposed to prenatal infection.

Objective: To assess the relationship between cigarette smoking during pregnancy and very preterm births, according to the main mechanisms of preterm birth.Design: Case-control study (the French Epipage study).Setting: Regionally defined population of births in France.Population: Eight hundred and sixty-four very preterm live-born singletons (between 27 and 32 completed weeks of gestation) and 567 unmatched full-term controls.Methods: Data from the French Epipage study were analysed using a polytomous logistic regression model to control for social and demographic characteristics, pre-pregnancy body mass index and obstetric history. The main mechanisms of preterm delivery were classified as gestational hypertension, antepartum haemorrhage, premature rupture of membranes, spontaneous preterm labour and other miscellaneous mechanisms.Main Outcome Measures: Odds ratios for very preterm birth for low to moderate (1-9 cigarettes/day) and heavy (>/=10 cigarettes/day) maternal smoking in pregnancy, estimated according to the main mechanisms leading to preterm birth.Results: Smokers were more likely to give birth to very preterm infants than non-smokers [adjusted odds ratio (aOR) 1.7, 95% confidence interval (CI) 1.3-2.2]. Heavy smoking significantly reduced the risk of very preterm birth due to gestational hypertension (aOR 0.5, 95% CI 0.3-1.0), whereas both low to moderate and heavy smoking increased the risk of very preterm birth due to all other mechanisms (aOR between 1.6 and 2.8).Conclusion: These data from the Epipage study show that maternal smoking during pregnancy is a risk factor for very preterm birth. The impact of maternal smoking on very preterm birth appears to be complex: it lowers the risk of very preterm birth due to gestational hypertension, but increases the risk of very preterm birth due to other mechanisms. These findings might explain why maternal smoking is more closely related to preterm birth among multiparous women than among nulliparous women. [ABSTRACT FROM AUTHOR]

Aim: To evaluate whether precociously treated subjects with congenital hypothyroidism (CH) are at risk of poor school performance in early adolescence, and to investigate which factors affect their school achievement.Methods: All children treated early for congenital hypothyroidism and born in France during the first 7 y (1979-1985) of the national screening program for congenital hypothyroidism were selected for the study. School performance during childhood, assessed according to age at entry into the first grade of secondary school, was evaluated as normal (usually 11 y of age) vs late entry (> or = 12 y). The national register of children with congenital hypothyroidism enabled a comparison to be made with data from the national population for the same school years.Results: School achievement was similar among the 682 patients with CH and in the national population. After an adjustment for the sex and socioprofessional category of the parents, the severity of CH as assessed by the type (athyreosis. the most severe vs other types), the initial low serum T4 levels (< or = 53 nmol/L vs >53 nmol/L), and the profound bone maturation delay (absence vs presence of the two knee epiphyseal ossification centres at diagnosis), initially low L-thyroxine dosage (below vs > or = 7 microg/kg/day), the absence of near normalization of thyroid hormone levels after 15 d of treatment and poor adequacy of treatment throughout childhood were associated with an increased risk of school delay. School achievement was unaffected by the age at start of treatment (mean age = 22.8 +/- 6.8 d). In a multivariate logistic regression analysis, recurrent episodes of insufficiently suppressed TSH levels (> or = 15 mUi/L at least four times during follow-up from the age of 6 mo onwards) were the most important variable associated with school delay.Conclusion: Careful follow-up of the adequacy of treatment is required throughout childhood, to reduce the risk of school delay.

This study analysed the characteristics of respondent and nonrespondent mothers at each stage of a survey procedure, from a initial questionnaire to a reminder letter and two repeated mailings. Of 938 mothers of liveborn children who, while maternity inpatients, received a questionnaire and information about a mail survey to follow 2 months later, 828 completed and returned the initial questionnaire, 708 agreed to participate in the mail survey and were sent the mail questionnaire, and 612 finally completed and returned the questionnaire at 2 months. There were differences between respondents and non-respondents for socio-demographic factors at each stage of the process. The final response rate to the mail questionnaire was higher among mothers who were younger, were breast feeding, and had more education, an occupation and fewer children. The characteristics of late respondents were intermediate between those of early to middle respondents and nonrespondents for age, educational level, breast feeding and occupation. Maternal and infant health varied only slightly according to response status. Repeated mailings increased response and diminished selection. A mail questionnaire after contact in a maternity ward is a cost-effective means of gathering data about a large sample of recent mothers and their children. [ABSTRACT FROM AUTHOR]

Objectives. This study investigated the effect of moderate prenatal alcohol exposure on psychomotor development of preschool-age children in a longitudinal study. Methods. Pregnant women were interviewed about their alcohol consumption at their first visit to the maternity hospital in Roubaix, France. Alcohol consumption before pregnancy and during the first trimester was assessed with a structured questionnaire. The psychomotor development of 155 children of these woman was assessed with the McCarthy scales of children's abilities when the children were about 4 1/2 years old. Results. Consumption of 1.5 oz of absolute alcohol (approximately three drinks) or more per day during pregnancy was significantly related to a decrease of 7 points in the mean score on the general cognitive index of the McCarthy scales, after gender, birth order, maternal education, score for family stimulation, family status, maternal employment, child's age at examination, and examiner were controlled for. Conclusions. This study showed that moderate to heavy alcohol consumption during pregnancy, at levels well below those associated with fetal alcohol syndrome, has effects on children's psychomotor development. [ABSTRACT FROM AUTHOR]

The teratogenic effects of alcohol have been recognized in the fetal alcohol syndrome. The syndrome is associated with very high levels of maternal consumption. Studies of the relation between much lower levels of consumption and pregnancy outcome seem to indicate consistently lower birthweight among children born to mothers drinking more than 140 g absolute alcohol per week, or about two drinks a day.

The article reports a study to determine mortality and development in the first year based on gestation type. Researchers examined a cohort of very pre-term births. Results of the study revealed that multiple pregnancy was associated with a lower rate of stillbirth than singleton. Among live born infants, a trend to a lower survival was seen in infants of multiple than single gestation. Infants born from multiple pregnancy had a higher percentage of motor delay. Researchers concluded that very pre-term infants from multiple gestations have a slight increased risk for mortality or delay of development in the first year compared with infants from single pregnancy.

The article reports a study that assessed the developmental outcome of very pre-term children at 1 year in a large population based cohort by questions to parents in a postal questionnaire. The study also examined the influence of gestational age, gender, intrauterine growth retardation and cerebral lesions at neonatal ultrasound on infant development. Results of the study revealed that the incidence of a delay increased with decreasing gestational age for motor score. The same pattern was seen for coordination and socialization scores. Researchers concluded that child developmental delay was related to lower gestational ages and severity of cerebral lesions.

The article reports a study to determine behavioural outcome at 3 years age in very premature infants in a regionally defined, prospective cohort study. Results of the study revealed that on the behaviour questionnaire, the very premature infants showed significantly higher difficulties than term children. Boys had higher total difficulty and hyperactivity scores. A lower socioeconomic status was related to a higher frequency of behavioural problems, which was significant for total difficulty score, conduct problems score and pro social behaviour score. Researchers concluded that the prevalence of behavioural problems assessed by parents at 3 years of very premature infants was higher than in term infants.
