Objectives: To evaluate the association of dietary patterns (DP) in the pre-gestational period with neonatal outcomes.
A prospective cohort (n=189) was followed in Rio de Janeiro, Brazil, during pregnancy (5-13th, 20-26th and 30-36th weeks) and 30-40 days postpartum. A food frequency questionnaire was administered at the 1st trimester. The reduced rank regression procedure was used to identify DP that explains the response variables: fiber density, dietary energy density, and % energy from saturated fat. Infants' birth weight and length were retrieved from medical records and classified according to Intergrowth-21st percentiles for sex and gestational age at birth [small and adequate for gestational age, ≤90th percentile vs. large for gestational age (LGA), > 90th percentile]. The Apgar score was measured at the 1st minute [<7(health risk) vs. ≥7 (normal)]. The associations between DP tertiles and the outcomes were determined using multiple logistic regression models. Confounders were established based on a Direct Acyclic Graph.
The pregnant woman had a mean daily energy intake of 2,422 kcal (SD 822). The mean (SD) birth weight and length was 3,277 g (529.7) and 49.6 cm (3.1), respectively. LGA occurred in 16% and Apgar <7in14.2%. Three DP were identified: 'fast food and candies' (characterized by high intakes of fast food and snacks, cakes/cookies/crackers, and candies/ desserts); 'beans, bread and fat' (characterized by high intakes of beans, cakes/cookies/crackers, bread and fats used as spreads); and 'vegetables and dairy' (characterized by high intakes of green vegetables/legumes, dairy products, fish, tea, fruits/fruit juices, and candies/desserts). In the adjusted logistic regression analysis women with the highest adherence to the 'fast food and candies' DP presented higher risk of LGA (OR=4.38, 95%CI: 1.27; 15.02) and birth length > 90thpercentile (OR=5.03, 95%CI: 1.85; 13.64) occurrence. The highest adherence to the 'beans, bread and fat' DP was inversely associated with Apgar at the 1st minute <7(OR=0.14, 95%CI: 0.03; 0.69). We found no associations between the 'vegetables and dairy' DP and neonatal outcomes.
The adherence to a 'fast food and candies' pre-pregnancy DP was positively associated with birth length and increased the risk of LGA births.
