To examine the association between breastfeeding duration and cognitive performance in adolescence, specifically using standardized mathematics and word recognition tests, while accounting for socioeconomic factors in China.
Approach:
Key Findings:
Longer breastfeeding duration was associated with better cognitive performance in adolescence, indicating a potential area for public health intervention.
The association persisted after adjusting for socioeconomic indicators, suggesting a robust link.
Cognitive performance varied significantly with age during early adolescence, highlighting the importance of timing in breastfeeding duration.
Interpretation:
The findings suggest that extended breastfeeding may have a beneficial impact on cognitive abilities, independent of socioeconomic status, particularly in the context of China's unique breastfeeding patterns, warranting public health strategies to promote longer breastfeeding durations.
Limitations:
The study's cross-sectional design limits causal inferences, making it difficult to establish direct cause-and-effect relationships.
Retrospective reporting of breastfeeding duration may introduce recall bias, potentially skewing results based on participants' memory.
The analysis may not account for all potential confounding factors, which could influence the observed associations.
Conclusion:
Promoting longer breastfeeding durations could be an important public health strategy to enhance cognitive development in children.
