Abstract

In spite of multiple benefits of physical activity (PA) for children and adolescents, health, as well as for prevention of chronic diseases later in life, detailed data concerning their PA is limited in our community. To determine the PA duration and intensity, as well as the energy expenditure in adolescents by a simple self-report. This cross-sectional study was performed among 2000 students, ages 11-18, selected by multi-stage random sampling and with equal proportion in both genders in middle and high school levels in Isfahan. A simple self-administered questionnaire consisting of 9 scales of PA from inactivity (0.9 METs) to vigorous activity (>6 METs) used in European countries was validated and filled out by 100 selected samples. Overall, 1894 filled questionnaires (94% of total) were returned. Statistical analysis was performed using the Student t and Pearson correlation tests at P<0.05. The mean age of subjects studied was 14.7±1.1 years in girls and 14.5+ 1.2 years in boys. The mean daily PA with an intensity of more than 2 METs in boys was significantly higher than girls 36.9±6.8 vs. 26.6 + 4.2,respectively, (P<0.001). The daily energy expenditure by activities with more than 2 METs of intensity in the middle school students was 1000.3 + 128.5 Kcal in girls, and 2395.6+172.4Kcal in boys (P<0.001). Considering the high school students, these values were 1469.8 + 190.7 and 2146.3 + 399.7 Kcal, respectively (P<0.001). In both genders, PA duration and level was lower in high school than middle school students. A significant inverse relationship was found between the mean daily PA with the mean weight (r=-0.64, P<0.001), and with the mean body mass index (r=-0.71, P<0.001). Findings of the present study provide a simple and valid self-report questionnaire and shows an undesirable PA level in adolescents especially females and high school students. This finding emphasizes the necessity to pay more attention to PA promotion in youth, and to provide facilities in this regard.
