Neonatal factors associated with early weaning in a municipality in Bahia, Brazil: a cross-sectional study

To analyze neonatal factors associated with early weaning. This is a cross-sectional study conducted between March and September 2023 with 180 women six months to two years postpartum, from a municipality in Bahia, Brazil. For bivariate analysis, Pearson's chi-square tests were used, considering p < 0.05. The adjusted analysis included variables with p < 0.20, keeping those with p < 0.05, using stepwise multiple logistic regression, with a 95% confidence interval. The provision of pacifiers/bottles (OR: 18.96; 95% CI: 7.68-46.79; p < 0.001) and supplements in the maternity ward (OR: 4.44; 95% CI: 1.76-11.17; p: 0.002) were associated with greater likelihood of early weaning. Habits and beliefs, such as the use of bottles and pacifiers, and the introduction of infant formulas within the maternity ward with continued supplementation after hospital discharge were the neonatal factors associated with early weaning in this context.
