Obesity in adolescents can continue up to adulthood and increases the chance of developing non-communicable diseases. An analytic cross-sectional study was done among secondary school students in Petaling district to determine prevalence and factors associated with obesity. Sampling with probability proportionate to size was used and 5 schools were selected. Self-administered pretested questionnaires in Bahasa Malaysia were used to capture the socio-demographic characteristics, physical activity, dietary pattern, smoking status and psychological factors (self-esteem & body image). Weight was measured to the nearest 0.1kg using a digital bathroom scale (TANITA model HD-319); height was measured by using SECA body meter model 206 to the nearest 0.1cm.The response rate was 90.7%. The prevalence of obesity among the respondents was 13.7% (95% CI= 12.3, 15.1). Males had a significantly higher prevalence of obesity 15.9% (95% CI= 14.4, 17.4) compared to females with 12.3% (95% CI= 10.94, 13.66). Malay respondents had the highest prevalence of 16.2% (95% CI = 14.68, 17.72), followed by Chinese with 11.5% (95% CI= 10.2, 12.8) and then Indians with prevalence of 10.5% (95% CI= 9.23, 11.77). Those with low physical activity had significantly higher prevalence of obesity than those with high physical activity (χ2 = 237, df = 1, p <0.001). Those with low self-esteem had significantly higher prevalence of obesity than those with normal self-esteem (χ2 = 143, df =1, p <0.001). Prevalence of obesity was also significantly higher among those with body parts dissatisfaction (χ2 = 10, df = 1, p <0.001) and body size dissatisfaction (χ2 = 90, df = 1, p <0.001). However, there was no statistical association between obesity and the dietary patterns (dietary pattern 1 χ2 = 5.919, df= 3, p = 0.116; dietary pattern 2 χ2 = 7.728, 3, p = 0.052; dietary pattern 3 χ2 = 5.923, df= 3, p = 0.115). Logistic regression was used to determine the predictors of obesity and the significant predictors of obesity were gender (Male’s odd ratio (OR) =2.389, 95% CI= 1.7, 3.3, p < 0.001), age (13 to <14 years OR =2.05, 95% CI = 1.1, 3.7, p =0.019; 14 to <15 years OR =2.95, 95% CI = 1.1, 3.6, p = 0.034), low physical activity (OR = 82.8, 95% CI = 45.5, 151.0, p < 0.001), low self-esteem (OR = 7.77, 95% CI = 5.15, 11.71, p < 0.001), body parts dissatisfaction (OR = 1.479, 95% CI = 1.2, 1.9, p = 0.002) and body size dissatisfaction (OR = 4.705, 95% CI = 2.6, 8.5, p < 0.001).In conclusion, this study has identified that the prevalence of obesity is high among adolescents and found to be associated with modifiable risk factors which are low physical activity, low self-esteem and body image dissatisfaction. The findings from this study can be used by policy makers to plan preventive measures to tackle the increasing prevalence of obesity.
