distribution of physical activity by gender and rbmi in overweight and obese students

abstract background: a wealth of study shows that increasing rbmi accompanies with physical inactivity, consequently. the aims of this study were determining the distribution of daily physical activity amount by gender in obese and overweight students methods: this is a cross-sectional descriptive study carried out to determine the distribution of daily physical activity level by genders and relative body mass index in overweight and obese children. we selected 300 students grade 5 th and 6 th randomly and studied their health profiles. so we selected those who were in the range of overweight and obesity based on national centre for health statistics (nchs). physical activities of the subjects were measured with a qualified questionnaire. findings: there was a significant difference between the prevalence of obesity and overweight between genders (p=0.000). overweight children, regardless to the gender they are, have higher daily physical activity than obese ones and statistical analyses shows significant differences between means of mpa, vpa and met by genders and relative body mass index (p=0.000). conclusion: as increasing rbmi is concomitant with increasing students' physical inactivity in both genders, it is important to prepare more qualified plan increasing physical activities in obese children rather than overweight ones.  key words: physical activity, relative body mass index, students
