ABSTRACT
Background and Aim: There is evidence that physical activity declines during adolescence in Western countries. However, this pattern has not yet been shown in Iranian youth. The purpose of this study was to detect changes in physical activity behaviors, psychological factors (including perceived benefits, barriers, and self-efficacy), and interpersonal influences associated with exercise behavior during the transition from secondary school to high school in Sanandaj, Iran.Materials and Methods: The data on a group of high school students in Sanadaj were collected in a cross-sectional study in 2006, with a follow-up in 2009. The study population in 2009 included 844 students (51% males and 49% females) with a mean age of 16.42 ± 1.73 years. Data on physical activity-related perceived benefits, barriers, self-efficacy, and interpersonal influences, as well as physical activity behavior, was collected, using self-reporting questionnaires. The SPSS-16 software was used for data analysis. Results: The test of time effects indicated significant differences between the 2 sexes as regards physical activity and most of the psychological variables and interpersonal influences associated with exercise activities. The girls had less physical activity than boys at both time points. The duration of moderate physical activity at the first time point was 31.82 and 53.75 minutes for girls and boys, respectively; the corresponding values at the follow-up were 23.7 and 44.7 minutes. Girls had lower self-efficacy and fewer perceived benefits and more perceived barriers for physical activity over time. The correlation test indicated more stability of family interpersonal influences for girls than for boys.Conclusion: The results of this study provide evidence for decreased physical activity in boys and girls and sex differences in cognitive variables and interpersonal influences.
