Abnormal gestational weight gain (GWG) is associated with adverse pregnancy outcomes. We examined whether dietary patterns are associated with GWG. Participants included 3374 pregnant women from a population-based cohort in the Netherlands. Dietary intake during pregnancy was assessed with food-frequency questionnaires. Three a posteriori-derived dietary patterns were identified using principal component analysis: a “Vegetable, oil and fish”, a “Nuts, high-fiber cereals and soy”, and a “Margarine, sugar and snacks” pattern. The a priori-defined dietary pattern was based on national dietary recommendations. Weight was repeatedly measured around 13, 20 and 30 weeks of pregnancy; pre-pregnancy and maximum weight were self-reported. Normal weight women with high adherence to the “Vegetable, oil and fish” pattern had higher early-pregnancy GWG than those with low adherence (43 g/week (95% CI 16; 69) for highest vs. lowest quartile (Q)). Adherence to the “Margarine, sugar and snacks” pattern was associated with a higher prevalence of excessive GWG (OR 1.45 (95% CI 1.06; 1.99) Q4 vs. Q1). Normal weight women with higher scores on the “Nuts, high-fiber cereals and soy” pattern had more moderate GWG than women with lower scores (−0.01 (95% CI −0.02; −0.00) per SD). The a priori-defined pattern was not associated with GWG. To conclude, specific dietary patterns may play a role in early pregnancy but are not consistently associated with GWG.
We studied the associations of maternal pre-pregnancy body mass index and gestational weight gain with risks of preschool wheezing in offspring and explored the role of growth, infectious and atopic mechanisms.This substudy of 4656 children was embedded in a population-based birth cohort. Information about maternal pre-pregnancy weight, gestational weight gain and wheezing at the ages of 1-4 years was obtained by either physical measurements or questionnaires.Among mothers with a history of asthma or atopy, maternal pre-pregnancy obesity was associated with an overall increased risk of preschool wheezing (odds ratio 1.47, 95% confidence interval 1.12-1.95). Also, each standard deviation increase of gestational weight gain was associated with an increased overall risk of preschool wheezing (1.09, 1.04-1.14), was independent of pre-pregnancy body mass index and was not different between mothers with and without a history of asthma or atopy. Child's growth, respiratory tract infections or eczema did not alter the results.Mothers with pre-pregnancy obesity and a history of asthma or atopy, and mothers with higher gestational weight gain showed higher risks of wheezing in their offspring. These associations could not be explained by growth, infectious or atopic mechanisms. Further research is needed to identify underlying mechanisms and long-term consequences. @ERSpublications Pre-pregnancy obesity associated with increased risk of wheezing in offspring, if mothers have history of asthma or atopy
Evidence to confirm the suggested effects of choline on health in different stages of life is scarce. Potential effects of choline need to be confirmed by intervention studies. Possible harmful effects on cardiometabolic health need careful evaluation.
Our findings suggest that higher dietary intake and higher blood concentrations of lutein are generally associated with better cardiometabolic health. However, evidence mainly comes from observational studies in adults, whereas large-scale intervention studies and studies of lutein during pregnancy and childhood are scarce.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
