RESUMO
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 women 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.

A cohort of 37 pre-term children was assessed for both morphosyntactical and for vocabulary skills at the age of 2 and again at the age of 3 years and 6 months. They were compared with two comparison groups of full-term children (adjusted age and chronological age). The results indicated (1) a clear asynchrony between the two components of language production assessed at both ages, (2) an accurate prediction of language delay at age 2 for pre-term children (35% of pre-term children were detected for morphosyntax as measured by Mean Length of Utterance and 27% of pre-term children were detected for vocabulary as measured by the number of different words) and, (3) no evidence on the relationship of language and motor development as measured by formal tests. Such findings strongly challenge the validity of standardized developmental tests and support to a certain extent the hypothesis that language development is independent of motor skills. A neurodevelopmental assessment is suggested.
