Abstract
BACKGROUND: Breastfeeding practices are determined by complex multilevel factors. This study assessed pregnant women's knowledge of breastfeeding and intention to breastfeed and investigated modifiable predictors for breastfeeding status (exclusive or any breastfeeding) and duration at 6 and 12 months postpartum. MATERIALS AND METHODS: Longitudinal data were extracted from a trial in Sydney, Australia, 2017-19. Women (n = 1155) were recruited from antenatal clinics and followed up for telephone interviews at baseline (third trimester), then at 6 and 12 months postpartum. Data collected included mothers' demographics; knowledge of breastfeeding and intention to breastfeed; work status; support from caregivers; breastfeeding environment; breastfeeding status and duration. Multiple logistic and Cox regression models were built to identify predictors for breastfeeding. RESULTS: At baseline, most mothers knew the recommendation to exclusively breastfeed until 6 months (66%) and the benefits (65%). The modifiable predictors for breastfeeding duration at 12 months included the following: mothers' knowledge of the recommendation (adjusted hazard ratio (AHR) 0.73, 95% confidence interval (CI) 0.60-0.90) and the benefits of exclusive breastfeeding (AHR 0.68, 95% CI 0.55-0.82), intention to meet the recommendation (AHR 0.76, 95% CI 0.63-0.93), and intention to breastfeed for two years (AHR 0.38, 95% CI 0.27-0.52) measured at baseline; mothers not working or studying (AHR 0.70, 95% CI 0.55-0.89), having support from other caregivers (AHR 0.64, 95% CI 0.43-0.96), and having breastfeeding women around (AHR 0.80, 95% CI 0.65-0.98) measured at 6 months. CONCLUSIONS: Support for women to meet the breastfeeding recommendations should commence during pregnancy and focus on breastfeeding education and enabling environments.
