Abstract
Maternal prenatal attitudes and postnatal breastfeeding behaviors in rural Bangladesh

Objective: We assessed the relationships between psychosocial constructs (maternal intention, attitudes, self-efficacy, breastfeeding knowledge) at 7 mo gestation and exclusive or full breastfeeding at 3 mo postpartum.

Design: Prospective longitudinal cohort study with structured home interviews during pregnancy and 3 mo after delivery.

Setting: Two rural sub-districts (Karimganj; Katiadi) of Kishoreganj district, Bangladesh.

Subjects: Mother-infant dyads.

Results: Over 75% of 1470 pregnant women intended to exclusively breastfeed (EBF). Maternal positive attitudes, self-efficacy, and knowledge about breastfeeding were positively associated with intentions to EBF during the 3rd trimester of pregnancy (all p<0.05). All mothers reported initiating breastfeeding, and nearly all children were still breastfed at 3 mo. According to 24-hour dietary recalls, we categorized 639 (43.5%) infants as EBF (47.2% among mothers with intention; 31.0% no intention), and 389 (26.5%) infants as predominantly breastfed (PBF) (25.2% intention; 30.7% no intention) at 3 mo. Prenatal maternal intention to EBF was associated with EBF (aOR 1.35, 95% CI: 1.02-1.80) and full breastfeeding (aOR 1.29, 95% CI: 0.98-1.70) at age 3 mo, adjusting for covariates. EBF and full breastfeeding at age 3 mo were not associated (p>0.05) with any other prenatal maternal psychosocial constructs examined, controlling for covariates.

Conclusions: Despite expressed maternal intentions to exclusively breastfeed during pregnancy and universal breastfeeding initiation, prevalences of both exclusive and full breastfeeding at 3 mo remain lower than WHO recommendations. Our findings indicate associations between EBF intention and postnatal breastfeeding behaviors, suggesting the importance of prenatal intention and psychosocial factors in supporting optimal infant feeding behaviors.
