Several studies have shown that breastfeeding has a protective effect on the risk of autism spectrum disorder and is associated with improved cognitive development later in childhood and adolescence.
To evaluate the association between suboptimal breastfeeding practices and autism spectrum disorders.
A case-control study was conducted among 102 ASD cases and 102 controls.
Adjusted odds ratios (OR) from logistic regression models, ASD was found to be associated with late initiation of breastfeeding (OR = 1.48; 95% CI 1.01, 3.1), non-intake of colostrum (OR = 1.7; 95% CI 1.03, 4.3), prelacteal feeding, and bottle feeding. The risk of ASD was found to decrease in a dose-response fashion over increasing periods of exclusive breastfeeding (trend p value = 0.04) and continued breastfeeding (trend p value = 0.001).
This study indicates that increased autism spectrum disorder risk is generally associated with suboptimal breastfeeding practices.
