Introduction:  In developed countries, overweight and obesity are important factors among children and adults. Overweight in childhood is an effective factor in incidence of chronic diseases, such as diabetes and insulin resistance, and overweight in adulthood. The aim of this study was to investigate the risk factors for childhood obesity to prevent type II diabetes. 

Materials and Methods: This was a case-control study. The case group included students who had a body mass  index percentile of 85% or higher (n=120). The control group comprised of students with body mass index percentile of 85% or lower (n=480). Children’s demographic characteristics, the child and parents’ weight, type of delivery, student’s weight at the time of entering elementary school, and nutritional status of the child were compared.

Results: The results showed that mothers’ and fathers’ weight in obese children were significantly higher compared to others (P=0.00 and P=0.024, respectively). Type of nutrition was significantly associated with obesity (P<0.05).

Conclusion: We recommend the consumption of low-fat dairy products, low-sugar marmalades, whole grain spaghetti, and standard fast foods as an alternative for non-standard and high-fat foods.
