Prepregnancy Obesity Class is a Risk Factor for Failure to Exclusively Breastfeed at Hospital Discharge among Latinas

Objectives: Examine whether exclusive breastfeeding status at hospital discharge among overweight and obese Latinas was associated with (1) prepregnancy body mass index (BMI) and gestational weight gain and (2) sociodemographic, psychosocial, and maternal/infant biomedical factors.

Methods: An electronic medical records review was conducted to determine exclusive breastfeeding status at hospital discharge among Latinas who gave birth at Hartford Hospital, Hartford, Connecticut, USA (N = 480). Eligible participants were ≥ 16 years, Latina, overweight or obese (BMI ≥ 25.0 kg/m²) and delivered a healthy full-term (≥ 37 weeks) singleton.

Results: In the multivariable model, obese class II (BMI, 35.0-39.9 kg/m²) women had increased odds of failing to exclusively breastfeed at hospital discharge compared with overweight women. Planned formula use/partial breastfeeding was the single strongest predictor of nonexclusive breastfeeding status. Other risk factors included Puerto Rican ethnicity and parity.

Conclusion: Maternal prepregnancy obesity class is an important predictor of exclusive breastfeeding status at hospital discharge among overweight and obese Latinas. Future research should examine why in-hospital exclusive breastfeeding behaviors differ by obesity class to subsequently inform the design of breastfeeding promotion and support interventions tailored to the needs of Latinas by obesity class. Culturally appropriate prenatal breastfeeding promotion interventions emphasizing action and coping planning should be considered.
