Abstract
Objectives This study investigated the association between maternal
pregravid body mass index (BMI) and breastfeeding discontinuation at 4-6
months postpartum in Hawaii and Puerto Rico participants from the
Special Supplemental Nutrition Program for Women, Infants, and Children
(WIC). Methods A secondary data analysis was conducted from a text
message-based intervention in WIC participants in Hawaii and Puerto
Rico. The analysis included 87 women from the control group who
initiated breastfeeding and whose breastfeeding status was known at the
end of the study when infants were 4-6 months old. Pregravid BMI and
breastfeeding discontinuation were assessed using questionnaires.
Results The association between pregravid BMI and breastfeeding
discontinuation was not significant in the unadjusted model or in the
adjusted model. Native Hawaiian or Other Pacific Islander (NHOPI)
participants showed significantly increased odds of discontinuing
breastfeeding (adjusted odds ratio [AOR] 7.12; 95% CI 1.34, 37.97; p =
.02) compared to all the other racial/ethnic participants, as did older
women ages 32-39 years versus women who were 25-31 years old (AOR 4.21;
95% CI 1.13, 15.72; p = .03). Women who took vitamins while
breastfeeding had decreased odds of discontinuing breastfeeding (AOR
0.15; 95% CI 0.05, 0.46; p = .0009). Conclusions for Practice Pregravid
BMI was not significantly associated with breastfeeding discontinuation
at 4-6 months postpartum in women from Hawaii and Puerto Rico WIC, but
NHOPIs and women who were older had higher odds of discontinuing
breastfeeding. The results of this study may inform strategies for
breastfeeding promotion and childhood obesity prevention but should be
further investigated in larger studies. ClinicalTrials.gov Identifier: NCT02903186.
