Material and methods : This cross sectional study was conducted on 3918 high school students. Accurate BMI perception occurred when the student’s self-perception of their BMI status did not differ from their actual BMI based on measured height and weight. Agreement between the measured and self-reported body height and weight and BMI values was determined using the Bland-Altman metod. To determine the effects of “a good level of agreement”, hierarchical logistic regression models were used. Results : Among male students who reported their BMI in the normal region, 2.8% were measured as overweight while 0.6% of them were measured as obese. For females in the same group, these percentages were 1.3% and 0.4% respectively. Among male students who perceived their BMI in the normal region, 8.5% were measured as overweight while 0.4% of them were measured as obese. For females these percentages were 25.6% and 1.8% respectively. According to logistic regression analysis, residence and accurate BMI perception were significantly associated with “good agreement” (p ≤ 0.001). Conclusions : The results of this study demonstrated that in determining obesity and overweight statuses, non-accurate weight perception is a potential risk for students. %A Gokler, Mehmet Enes %A Bugrul, Necati %A Sarı, Ahu Ozturk %A Metintas, Selma %P 174-181 %9 journal article %R 10.5114/aoms.2016.61401 %U http://dx.doi.org/10.5114/aoms.2016.61401
