Background and Objective: Child obesity is increased in developing countries.

Results: In this study, 6.4% of children were obese. Prevalence of obesity was not significantly different between boys and girls (5.4% and 7.4% respectively). Breast feeding duration<18 months (P<0.005) and formula or cow’s milk plus breast feeding up to 6 months old (P<0.01) was significantly correlated with children’s obesity. Breast feeding duration more than 18 months reduced the obesity risk factor with 64%. Conclusion: This study demonestrated that exclusively breast feeding in the first 6 months of life and breast feeding duration more than 18 months reduce the child obesity
