Prevalence and factors associated with no intention to exclusively breastfeed for the first 6 months of life

Abstract

Objective: To investigate the prevalence and factors associated with no intention to exclusively breastfeed for the first 6 months of life in a sample of women in the first 24 h postpartum during the hospital stay. Methods: Cross-sectional study with data from screening phase of a birth cohort. The proportion of mothers who did not intend to breastfeed exclusively for 6 months (primary outcome) derived from a negative response to the question “Would you be willing to try to breastfeed exclusively for the first 6 months?”, in an interview conducted by previously trained interviewers. Crude and adjusted prevalence ratios (PR) with 95% confidence intervals were obtained by Poisson regression with robust variance. Results: A total of 2964 postpartum women were interviewed. The overall prevalence of mothers who did not intend to breastfeed exclusively for 6 months was 17.8% (16.4−19.1%). After adjusting for maternal age and type of pregnancy (singleton or multiple), no intention to exclusively breastfeed was higher in mothers with a monthly household income < 3 minimum wages (PR, 1.64; 1.35−1.98) and in those who intended to smoke 4−7 days/week after delivery (PR, 1.42; 1.11−1.83). The presence of significant newborn morbidity (PR, 0.32; 0.19−0.54) and intention to breastfeed up to 12 months (PR, 0.46; 0.38−0.55) had a protective effect against not intending to breastfeed exclusively for 6 months. Conclusions: Approximately 1 in every 5 mothers did not intend to breastfeed exclusively for 6 months. Strategies aimed at promoting exclusive breastfeeding should focus attention on mothers from lower economic strata and smokers.
