Little is known about how psychosocial factors (PSF) influence breastfeeding (BF) behavior of obese women. Our objectives were to determine a) whether maternal prepregnancy body mass index (BMI) is associated with social knowledge of, social influence towards, maternal confidence in, and behavioral beliefs about BF; b) whether these PSF predict BF outcomes; and c) whether prepregnancy BMI is associated with these outcomes, independent of the PSF. Longitudinal data from the Infant Feeding Practices Study II ( n =2890) were analyzed using logistic and proportional hazards regression models. Prepregnancy BMI was associated with confidence in ( P <0.0001), social influence towards ( P =0.04), and social knowledge of BF ( P <0.0001), but not with behavioral beliefs in BF ( P =0.48). Overweight and obese women did not differ from normal‐BMI women in intention to breastfeed ( P =0.06), but they had lower odds of ever BF ( P =0.03), and were at greater risk of ceasing exclusive ( P =0.0008) and any BF ( P =0.02) earlier. Only the association with exclusive BF remained significant ( P =0.01) after controlling for PSF. All the PSF were positively associated with each BF outcome. We conclude that women with high prepregnancy BMI have psychosocial characteristics associated with poor BF outcomes, despite having strong intentions to breastfeed.
