Objective: The vitamin A precursor β-carotene is recognized to promote mammalian embryonic development by serving as a source of retinoids to the developing tissues. The present study describes the predictors of serum β-carotene at third trimester of pregnancy.
Methods: Prospective study in the urban area of Cruzeiro do Sul, Acre state, Western Brazilian Amazon. A total of 472 pregnant women attending pre-natal care at primary health units were enrolled in the study. Demographic, socioeconomic, and clinical characteristics, as well as obstetric history, anthropometric, dietary, and biochemical data were gathered at baseline (mean and SD gestational age week: 20.03 ± 2.91). Serum β-carotene was measured by HPLC at third trimester of pregnancy (gestational age week: 27.76 ± 1.61). Multiple linear regression models with hierarchical selection of independent variables were used to evaluate associations with serum β-carotene (log-transformed). Data analysis was performed in Stata 14.0 with p < 0.05.
Results: A positive association with serum β-carotene at third trimester of pregnancy was observed for daily intake of fruits and vegetables (β=0.157; 95% CI: 0.004, 0.311) and serum vitamin E levels (β=0.030; 95% CI: 0.022, 0.037). In contrast, serum folate levels (β=-0.0154485; 95% CI: -0.028, -0.003) and receiving benefits from the Bolsa Família cash transfer program (β=-0.185; 95% CI: -0.349, -0.021) were negatively associated with β-carotene status in pregnancy (R2-adj=16.6% for full adjusted model).
Conclusion: In this study, the consumption of fruits and vegetables at the mid-pregnancy was an important predictor of serum β-carotene levels at third trimester of pregnancy.
