Objective: During adolescence, unhealthy body weight status is considered as a global concern as it may lead to adverse health consequences in adulthood, therefore evaluation of the risk factors is crucial. The aim of the study was to determine the prevalence of adolescents under the risk of being underweight, overweight, and obese among 14-17-year-old Turkish adolescents. In addition, we examined the association between unhealthy body weight categories and lifestyle factors. Methods: This study was designed as cross-sectional study which included body weight status and associated parameters of 1561 adolescents aged between 14 and 17 who were registered 25 different high schools in Istanbul, Uskudar. Height and body weight of participants were measured and related factors were obtained through a questionnaire. Differences in distributions were analyzed using the Chi-square test and to control confounding factors, multivariate logistic regression analysis was performed. As statistical significance limit of p<0.05 was determined. Results: Body mass index (BMI) percentile analyses indicated that 3.6% of participants were underweight, 14.3% were overweight, and 13.8% were obese. We demonstrated that age, gender, and school types were statistically very significantly associated with BMI (p<0.001) and daily meal frequency, eating speed, and mealtime regularity were significantly related with BMI (p<0.05). In addition, according to multivariate analysis results, gender and school types were closely related with obesity among 14-17-year old Turkish adolescents. Conclusion: This study has been demonstrated that frequency of adolescent obesity in Istanbul, Turkey, has increased and obesity closely related to gender and type of school. Further educational and interventional studies should be organized in this region with consideration of relevant risk factors.
