This narrative review examined the link between breastfeeding duration and childhood obesity risk. It looked at data from high-income countries involving both breastfed and formula-fed infants. The analysis covered outcomes like growth trajectories and rapid weight gain.
The review found that longer breastfeeding was associated with a reduced risk of childhood overweight and obesity. Infants who were breastfed exclusively showed healthier growth patterns and lower rates of rapid weight gain. Adiposity levels were also reduced in this group.
However, the study has important limitations. It noted methodological differences and inconsistent breastfeeding practices across the included data. The analysis also did not fully adjust for confounders such as maternal BMI and socioeconomic status. Because this is a narrative review, it cannot prove that breastfeeding causes these benefits. The evidence shows an association rather than a direct cause.
Readers should understand that promoting exclusive breastfeeding for at least six months remains a cornerstone of public health strategies to prevent childhood obesity. This information is based on existing research rather than new clinical trials.
