Abstract: The objective was to determine if breast feeding can influence the prevalence of atopic dermatitis among children. The target population of the study was all children participating in health check-up program for 3-year-old children in 60 municipalities locating 10 selected prefectures during designated 2 months between October and December 1997. Using a questionnaire, information on nutrition in infancy (breast milk only, bottled milk only, or mixed), parity, mothers' age at birth, and a history of atopic dermatitis was obtained. Furthermore, data on potential confounding factors were obtained. Questionnaires from 3856 children were analyzed. After adjustment for all potential confounding factors using unconditional logistic models, the risk of atopic dermatitis was slightly higher among breastfed children (odds ratio [OR] = 1.16 with 95% confidence interval [CI] 0.96-1.40). Mothers' age at birth (OR for those who were more than 30 years or older in comparison with those who were younger than 30 years = 1.15; 95% CI, 0.96-1.37) and those with second or later parity orders (OR = 1.14, 95% CI; 0.95-1.35) showed odds ratios that were higher than unity without statistical significance. CONCLUSION: Breast feeding tends to slightly increase the risk of atopic dermatitis; the risk may be higher in children in second or more birth order.
