Abstract

Background: Excessive gestational weight gain and rapid infancy weight gain (RIWG) are associated with increased susceptibility to childhood obesity. Since low-income and minority children are particularly at risk, investigation of the associations between gestational weight gain and rate of infancy weight gain may inform childhood obesity prevention. This study investigated the associations between gestational weight gain and rate of infancy weight gain during the first four to six months postpartum in participants from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Hawai‘i and Puerto Rico.

Methods: This was a cross-sectional secondary data analysis from a text message-based intervention in WIC participants in Hawai‘i and Puerto Rico. The analysis included 80 mother/infant pairs from the control group who completed the follow-up visit when infants were four to six months old. Maternal weight, height, and gestational weight gain were self-reported. Infant weight was measured at baseline and follow-up. A proportional odds model was used to investigate the association between gestational weight gain and infancy weight gain rate (rapid or extremely rapid, on-track, or slow), adjusting for maternal age, pregravid body mass index (BMI) status, parity, and being up-to-date with infant vaccinations.

Results: In comparison to recommended gestational weight gain, excessive and inadequate (under the recommended amount) gestational weight gain was associated with 77% decreased (adjusted odds ratio [AOR] = 0.23; 95% confidence interval [CI] = 0.08, 0.70; p = 0.01) and 71% decreased (AOR = 0.29; 95% CI = 0.09, 0.94; p = 0.04) odds of RIWG versus on-track or slow infant weight gain, respectively. In comparison to women with one child, women with two children (AOR = 0.31; 95% CI = 0.11, 0.87; p = 0.03) or three or four children (AOR = 0.24; 95% CI = 0.07, 0.88; p = 0.03) had significantly lower odds of RIWG versus on-track or slow infancy weight gain.

Conclusions: Women with excessive or inadequate gestational weight gain had lower proportional odds of RIWG and were more likely to have slower infant weight gain than women who gained the recommended amount of weight.
