Abstract

Background Small for gestational age (SGA) birthweight, a risk factor of infant mortality and delayed child development, is associated with maternal educational attainment. Maternal tobacco smoking during pregnancy could contribute to this association. We aimed to quantify the contribution of maternal smoking during pregnancy to social inequalities in child birthweight for gestational age (GA). Methods Data come from the French nation-wide ELFE cohort study, which included 17,155 singletons. Birthweights for GA were calculated using z-scores. Associations between maternal educational attainment, tobacco smoking during pregnancy and child birthweight for GA were ascertained using mediation analysis. Mediation analyses were also stratified by maternal pre-pregnancy body mass index.Results Low maternal educational attainment was associated with an increased odd of tobacco smoking during pregnancy (adjusted OR (ORa)=2.58 [95% CI 2.34, 2.84]) as well as a decrease in child birthweight for GA (RRa=0.94 [95% 0.91, 0.98]). Tobacco smoking during pregnancy was associated with a decrease in offspring birthweight for GA (RRa=0.73 [95% CI 0.70, 0.76]). Mediation analysis suggests that 39% of the effect of low maternal educational attainment on offspring birthweight for GA was mediated by smoking during pregnancy. A more important direct effect of maternal educational attainment on child birthweight for GA was observed among underweight women (RRa=0.82 [95%CI 0.72, 0.93]).Conclusions The relationship between maternal educational attainment and child birthweight for GA is strongly mediated by smoking during pregnancy. Reducing maternal smoking could lessen the occurrence of infant SGA and decrease socioeconomic inequalities in birthweight for GA.Keywords Birthweight, educational attainment, tobacco smoking, pregnancy, mediation analysis, health inequalities

Abstract

International audience; Although several studies have shown a positive association between socio-economic position and size at birth, not enough is known about the modifiable factors that may be involved. We aimed to investigate whether maternal prepregnancy body mass index (BMI), smoking, diet, and depression during pregnancy mediate the positive association between maternal education and birth size. Weight and length z-scores specific for gestational age and sex were calculated for 1,500 children from the EDEN mother-child cohort. A mediation analysis of the associations between maternal education and birth size was conducted with a counterfactual method, adjusted for recruitment centre, parity, maternal height, and age. In the comparison of children of mothers with low versus intermediate education levels, maternal smoking during pregnancy explained 52% of the total effect of education on birth weight. Similar findings were observed with birth length z-score (37%). The comparison of children of mothers with high versus intermediate education levels yielded a non-significant total effect, which masked opposite mediating effects by maternal BMI and smoking during pregnancy on both birth weight and length. Prepregnancy BMI and maternal smoking during pregnancy mediate the positive association between maternal education and birth weight and length z-scores. These mediators, however, act in opposite directions, thereby masking the extent to which healthy prenatal growth is socially differentiated.
