OBJECTIVE: To explore whether maternal vitamin B12 and folate status during early pregnancy are associated with cardiometabolic risk factors in the offspring at age 5-6.
DESIGN: Prospective multi-ethnic birth cohort, the Amsterdam Born Children and their Development study (ABCD).
SETTING: 12,373 pregnant women living in Amsterdam were approached between 2003 and 2004 for participation in the study.
POPULATION: Mother-child pairs for whom information on maternal vitamin B12 or folate status in early gestation and health at age 5-6 years was available (n = 1950).
METHODS: Vitamin B12 and folate concentrations were determined in maternal serum at intake in early pregnancy (median 13 weeks' gestation). Anthropometric measurements, blood pressure and fasting blood samples were collected during a health check of children aged 5-6 years. Multiple linear regression was performed to investigate the association between maternal serum concentrations and children's outcomes, corrected for confounders.
MAIN OUTCOME MEASURES: Gestational age at birth, birthweight, body mass index (BMI), glucose levels, triglyceride levels, blood pressure and heart rate of the offspring at age 5-6.
RESULTS: Low maternal folate levels during early pregnancy were associated with slightly higher BMI in the offspring [decrease per 10 units: β 0.07 kg/m(2), 95% confidence interval (CI) 0.01, 0.13]. Low maternal vitamin B12 concentrations were associated with higher heart rates (decrease per 100 units: β 0.49 beats/min, 95% CI 0.11, 0.87).
CONCLUSION: This study provides further evidence that maternal nutrition in early pregnancy may possibly program cardiometabolic health of the offspring.
TWEETABLE ABSTRACT: Low folate and vitamin B12 levels during pregnancy are associated with higher BMI and heart rate in offspring.
