Subjects of study were children between age group of 5-12 years attending selected government and private schools. By using appropriate statistical methods, sample size required for estimating a prevalence of obesity was found to be 2400. Cluster sampling technique is used. From a list of all schools, two strata were made as government schools and private schools from which three private schools and two government schools were selected using a simple random method. Absentees and those who have not given parental consent were excluded. Study variables are age, sex, socioeconomic status, birth weight, blood pressure, maternal education, television viewing, monthly income of parents, government/private school and family size.

X² test for overweight showed the relation of age and gender with overweight is significant (p value 0.001 and 0.041, respectively). X² test for overweight and school showed that the relation between overweight and school is significant. X² test for obesity and birth weight shows that there is positive correlation between obesity and birth weight (p value=0.042). X² test for obesity and television watching shows significant correlation. Similarly, there was no significant correlation between maternal education and overweight in children.
