Maternal dietary intake of dioxins and polychlorinated biphenyls and birth size in the Norwegian Mother and Child Cohort Study (MoBa)

Abstract Objectives This study analyzed the association between pre-pregnancy body mass index (PPBMI), dietary intake status, and birth size outcomes in the VDPM cohort study in West Sumatra, Indonesia. Methods The VDPM study is a prospective longitudinal study including 239 healthy pregnant women of Indonesian women with singleton pregnancies. Data on maternal dietary intake including energy, carbohydrate, protein, and fat intake, and anthropometry were collected during pregnancy. New-born anthropometry for 195 new-born babies was measured immediately after delivery. Bivariate and multivariate regression analyses were constructed to determine the association between PPBMI, dietary intake status, and birth size outcomes. Results The mean birth weight was 3195 ± 463 g. Dietary intake of pregnant mothers had a significant correlation with newborn birth weight, length of birth, head circumference, and placental weight as pregnancy outcome indicators (p ≤ 0.05). This study showed that no association between pre-pregnancy BMI status and birth size outcomes (p ≥ 0.05). Conclusions Our studies have not shown a statistically significant difference between PPBMI and birth size outcomes. However, maternal dietary intake associated with birth size outcomes, more research is warranted to confirm these findings. Funding Sources Indonesian Danone Institute Foundation.

Results from previous studies on associations between maternal fish and seafood intakes and fetal growth are inconclusive. The aim of the present study was to investigate how maternal intakes of seafood, subtypes of seafood and supplementary n-3 fatty acids were associated with infant birth weight, length and head circumference in a prospective study in Norway. The study population included 62 099 participants in the Norwegian Mother and Child Cohort Study. The mothers answered an FFQ in mid pregnancy. The FFQ comprised detailed questions about intake of various seafood items and n-3 supplements. Data on infant birth weight, length and head circumference were obtained from the Medical Birth Registry. We used multivariable regression to examine how total seafood, various seafood subtypes and supplementary n-3 intakes were associated with birth size measures. Total seafood intake was positively associated with birth weight and head circumference. Lean fish was positively associated with all birth size measures; shellfish was positively associated with birth weight, while fatty fish was not associated with any birth size measures. Intake of supplementary n-3 was negatively associated with head circumference. The relative risk of giving birth to a small baby ( < 2500 g) in full-term pregnancies was significantly lower in women who consumed >60 g/d of seafood than in women who consumed ≤ 5 g/d (OR = 0·56 (95 % CI 0·35, 0·88). In conclusion, maternal seafood consumption was positively associated with birth size, driven by lean fish intake, while supplementary n-3 intake was negatively associated with infant head circumference.
