Abstract

Objective To examine maternal pre-pregnancy (preconception) predictors of birthweight and fetal growth for singleton live births occurring over a 2-year period in a prospective study. Methods Data are from a population-based cohort study of 1,420 women who were interviewed at baseline and 2-years later; self-report data and birth records were obtained for incident live births during the followup period. The analytic sample includes 116 singleton births. Baseline preconception maternal health status and health-related behaviors were examined as predictors of birthweight and fetal growth, controlling for prenatal and sociodemographic variables, using multiple regression analysis. Results Preconception BMI (overweight or obese) and vegetable consumption (at least one serving per day) had statistically significant independent and positive effects on birthweight and fetal growth. Maternal weight gain during pregnancy, a prenatal variable, was an additional independent predictor of birthweight and fetal growth. Sociodemographic variables were not significant predictors after controlling for preconception and prenatal maternal characteristics. Conclusions Findings confirm that preconception maternal health status and health-related behaviors can affect birthweight and fetal growth independent of prenatal and socioeconomic variables. Implications for preconception care are discussed.
