Maternal Metabolic Factors during Pregnancy Predict Early Childhood Growth Trajectories and Obesity Risk: the CANDLE Study

BACKGROUND: We investigated the individual and additive effects of three modifiable maternal metabolic factors, including pre-pregnancy overweight/obesity, gestational weight gain (GWG), and gestational diabetes mellitus (GDM), on early childhood growth trajectories and obesity risk.

Sumario:BACKGROUND: We investigated the individual and additive effects of three modifiable maternal metabolic factors, including pre-pregnancy overweight/obesity, gestational weight gain (GWG), and gestational diabetes mellitus (GDM), on early childhood growth trajectories and obesity risk. METHODS: A total of 1 425 mother-offspring dyads (953 black and 472 white) from a longitudinal birth cohort were included in this study. Latent class growth modeling was performed to identify the trajectories of body mass index (BMI) from birth to four years in children. Poisson regression models were used to examine the associations between the maternal metabolic risk factors and child BMI trajectories and obesity risk at four years. RESULTS: We identified three discrete BMI trajectory groups, characterized as rising-high-BMI (12.6%), moderate-BMI (61.0%), or low-BMI (26.4%) growth. Both maternal pre-pregnancy obesity (adjusted relative risk [adjRR] = 1.96; 95% CI: 1.36–2.83) and excessive GWG (adjRR = 1.71, 95% CI: 1.13–2.58) were significantly associated with the rising-high-BMI trajectory, as manifested by rapid weight gain during infancy and a stable but high BMI until four years. All three maternal metabolic indices were significantly associated with childhood obesity at age four years (adjRR for pre-pregnancy obesity = 2.24, 95% CI: 1.62–3.10; adjRR for excessive GWG = 1.46, 95% CI: 1.01–2.09; and adjRR for GDM = 2.14, 95% = 1.47–3.12). In addition, risk of rising-high BMI trajectory or obesity at age four was stronger among mothers with more than one metabolic risk factor. We did not observe any difference in these associations by race. CONCLUSION: Maternal pre-pregnancy obesity, excessive GWG, and GDM individually and jointly predict rapid growth and obesity at age four in offspring, regardless of race. Interventions targeting maternal obesity and metabolism may prevent or slow the rate of development of childhood obesity.
