AI Article Synopsis
- * It involved a sample of 626 women, analyzing their dietary habits alongside factors like BMI, weight gain during pregnancy, and whether the baby was male or female.
- * Results indicated that higher intake of vitamins B and C, along with factors like maternal BMI and gestational weight gain, were linked to increased birth weights, together accounting for 27% of the variation in birth weight.
Article Abstract
Objectives: The objective of this study was to examine the influence of maternal nutrient intake during pregnancy on the baby's birth weight at term.
Methods: A cross-sectional study design was used to evaluate a sample of women aged 18 to 44 y in the postpartum period in a public maternity department (2018-2019), with dietary intake collected by a validated food frequency questionnaire (n = 626 mother-offspring pairs). A multivariable linear regression model was used to identify the influence of nutrient intake during pregnancy on the baby's birth weight at term. The model was adjusted for maternal energy intake, education level, gestational age, physical activity, and supplementation during pregnancy.
Results: Maternal intake of vitamins B and C was associated with an increase in birth weight (respectively, β = 0.01; 95% confidence interval [CI], 0.01-0.02; P = 0.01; and β = 0.01; 95% CI, 0.01-0.02; P = 0.02). Prepregnancy body mass index (β = 0.01; 95% CI, 0.01-0.02; P = 0.001), gestational weight gain (β = 0.02; 95% CI, 0.01-0.02; P < 0.001), parity (β = 0.05; 95% CI, 0.02-0.09; P = 0.001), and male babies (β = 0.08; 95% CI, 0.01-0.02; P = 0.02) also contributed to increase birth weight. These variables explained about 27% of the variation of this outcome (adjusted R = 0.27, P < 0.001).
Conclusions: Our findings provide evidence that maternal intake of vitamins B and C influences increased birth weight. In addition, prepregnancy body mass index, gestational weight gain, parity, and male babies contribute to the same outcome.

Infant undernutrition, defined by length- and weight-based indices, is common in low- and middle-income countries (LMICs), but corresponding deficits in head size have received less attention. In a cohort of term newborns in Dhaka, Bangladesh, we compared the severity of deficits (vs. World Health Organization Growth Standards) in head circumference (HC), length and weight at birth and every 3 months until 2 years of age (n range across timepoints: 843-920).
