Results are reported in terms of number (%).
*p value for unadjusted OR obtained using either Fisher's exact test or χ2 test.
†Adjusted for actual body mass index status, child's and parents perception of body weight and sociodemographic factors.
‡Obtained by fitting binary logistic regression model. Model 1: adjusted for sociodemographic variables and actual and perceived weight.
§Obtained by fitting binary logistic regression model. Model 2: adjusted for age, gender, medium of instruction, actual weight status and the child's perception of body weight.
