BackgroundThe role played by dairy product intake during pregnancy on neonatal outcomes has raised interest in the last few years. However, studies on this association remain scarce. Thus, the aim of this study was to determine the association between dairy product consumption during pregnancy and neonatal and maternal outcomes.
MethodsA prospective study was conducted with 98 pregnant women, aged 18–40, from the city of Porto, Portugal. Socio-demographic and lifestyle characteristics were assessed through a questionnaire. Dairy product consumption was assessed with a three-day food diary completed during the first and second trimesters. Postpartum medical records were examined for neonatal and maternal outcomes. Multivariate linear regression analyses were performed to assess the association between dairy intake and neonatal and maternal outcomes, adjusting for dietary variables and maternal characteristics.
ResultsCompared to the first trimester pregnant women had higher energy intake and lower calcium, iodine and yogurt intake in the second trimester (P < 0.05). Total dairy and yogurt intake in the first trimester were positively associated with head circumference and placental weight (respectively β = 0.002, P = 0.014, β = 0.333, P = 0.012). Change in total dairy intake between the second and first trimester was negatively associated with maternal weight gain during pregnancy (β = −0.007, P = 0.020).
ConclusionThe findings of this study suggest that dairy product intake during pregnancy may have an effect on neonatal head circumference, placental weight, and gestational weight gain
