However, studies on this associ- ation remain scarce. Thus, the aim of this study was to determine the association between dairy product consumption during pregnancy and neonatal and maternal outcomes. Methods: A 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. ∗ Corresponding author at: Faculty of Sport, University of Porto, Research Centre in Physical Activity, Health and Leisure, Rua Dr. Plácido Costa, 91 Porto, Porto 4200-450, Portugal.
