Aim: To estimate obesity prevalence of children aged 10-15 years and to find out the determinants of obesity in these children. Material and method: A cross-sectional study was conducted. Study population consisted of 306 children aged 10-15 years in elementary and secondary schools in Larissa. Data collection performed during May 2015. Response rate was 86.9% (=306/352). Children were classified as underweight, normal (healthy weight), overweight and obese according to body mass index, age and gender. Determinants under study were demographic characteristics, TV watching, personal computer use, internet use, physical activity, nutritional habits, sleeping habits and attitudes towards diet issues. Data analysis included x2 test, x2 trend test, t test, Mann-Whitney test and multivariate logistic regression analysis and performed with IBM SPSS 21.0. Results: Fifty percent of the children were females, mean age was 12.68 years and mean body mass index was 18.51kg/m2. Seventy-seven point five percent of the children were normal, 12.1% were overweight, 10.1% were underweight and 0.3% were obese. Nineteen point six percent of males and 4.6% of females were overweight, while 0.6% of females and 0% of males were obese. Multivariate logistic regression analysis identified that males (odds ratio [OR]=3.54, 95% confidence interval [CI]=1.51 to 8.31, p value=0.004), children with TV in their room (OR=2.73, 95% CI=1.26 to 5.92, p value=0.011) and children that used personal computer/video games machines/mobiles/tablets (OR=3.24, 95% CI=1.42 to 7.37, p value=0.005) were more overweight/obese. Conclusions: Gender, TV in children’ room and increased use of personal computer/video games machines/mobiles/tablets associated with overweight/obesity. Identification of obesity determinants in children is necessary for development and application of the appropriate health policies.
