This study was conducted to determine the nutritional and physical activity statuses of adolescents and to examine the relationship between their nutritional and physical activity levels and anthropometric measurements. The sample of this study was composed of 2.000 students from 20 secondary schools in Istanbul, Turkey. The physical activity levels were also examined using the survey, food consumption levels were determined by applying the 24-h Dietary Recall.

Among the male students (n = 888), 50.9% were normal weighted, 25.8% were overweight, 19.2% were obese, and 2.2% were severely obese. The percentage of those who were normal weight was higher (65.5%) among the female adolescents (n = 852), and 21.8% of the females were overweight, 10.2% were obese, and 0.9% were severely obese.
