Anemia in pregnancy is a key public health problem in both developing and industrialized countries that contributes to poor maternal and fetal outcomes. This longitudinal study aimed to assess maternal anemia and its association with maternal dietary intake and neonatal birth weight at a tertiary care hospital in Sri Lanka. Secondary data of first and third-trimester maternal hemoglobin concentrations were used. Dietary intake was assessed using a food frequency questionnaire, performed once in the second and third-trimesters. Birth weight was obtained from the hospital records. The chi-square test and the two-sample t-test were used to compare the anemic and non-anemic groups. Both univariate analysis of variance and generalized linear model were used to identify the effects of hemoglobin levels on birth weight. No difference in birth weight was found between first-trimester anemic and non-anemic women (p > 0.05). The babies whose mothers were anemic during the third trimester were 350 g lighter than those born to women who were not anemic during the third-trimester (95% CI: 66 to 634; p = 0.017). No differences in dietary intake were found between third-trimester anemic and non-anemic women (p > 0.05). The results suggest that third-trimester maternal anemia is associated with a low mean birth weight. The high prevalence of third-trimester maternal anemia among Sri Lankan women cannot be explained solely by macro and micronutrient deficiencies.
