Abstract
The association between breastfeeding and Kawasaki disease is not fully understood. We performed a case-control study to examine the association between breastfeeding and Kawasaki disease. In this study, 389 children diagnosed with Kawasaki disease and 426 gender- and age-matched controls were identified at Renmin Hospital of Wuhan University between November 2013 and March 2019. Demographic and clinical data were collected from a structured telephone interview and medical record database. Odds ratio and 95% confidence interval for risk of Kawasaki disease were estimated. Children who were breastfed exclusively had a decrease in developing Kawasaki disease (adjusted odds ratios and 95% confidence intervals 0.53 (0.38-0.74). Although the risk reduction was not statistically different, partial breastfeeding also provided a protective effect (adjusted odds ratios and 95% confidence intervals 0.70 (0.48-1.01). In the stratified analysis, we still observed that exclusive breastfeeding was inversely associated with the development of complete Kawasaki disease (adjusted odds ratios and 95% confidence intervals 0.52 (0.31-0.88) and incomplete Kawasaki disease (adjusted odds ratios and 95% confidence intervals 0.54 (0.38-0.77). However, there was no significant association between exclusive breastfeeding and the intravenous immunoglobulin treatment response (adjusted odds ratios and 95% confidence intervals 0.69 (0.27-1.69) and the risk of coronary artery lesions (adjusted odds ratios and 95% confidence intervals 0.79 (0.49-1.31) in Kawasaki disease. Conclusion: Our analysis suggests that exclusive breastfeeding was inversely associated with the development of Kawasaki disease and that breastfeeding might be a potential protective factor against Kawasaki diseaseWhat is known• Previous studies have demonstrated that breastfeeding has been shown to potentially confer protection against several autoimmune disorders of childhood.• The association between breastfeeding and Kawasaki disease is not fully understood.What is newThe first study to evaluate the association between breastfeeding and the development of Kawasaki disease in China with a large sample size.• Exclusive breastfeeding was inversely associated with the development of Kawasaki disease and breastfeeding might be a potential protective factor against Kawasaki disease.
