TI  - Relative contribution of physical activity, sedentary behaviors, and dietary 
      habits to the prevalence of obesity among Kuwaiti adolescents.
PG  - 6-13
AB  - BACKGROUND: The increasing rate of obesity among Kuwaiti adolescents is 
      associated with immediate and long term-risks to their health and well-being. 
      OBJECTIVE: To update data on the prevalence of overweight and obesity among 
      Kuwaiti adolescents and to examine the relative contribution of selected 
      lifestyle factors to overweight and obesity in this population. METHODS: The 
      present study is part of the Arab Teens Lifestyle Study (ATLS). A total of 906 
      adolescents (463 boys and 443 girls) aged between 14 and 19 years were selected 
      from Kuwaiti schools by a multistage stratified randomization process. A 
      validated questionnaire was used to collect data on physical activity, sedentary 
      lifestyle, and eating habits. The International Obesity Task Force (IOTF) cutoff 
      values for adolescents under 18 years of age were used to define overweight and 
      obesity. Total energy expenditure was calculated using metabolic 
      equivalent-minutes per week. A general linear model was used to establish the 
      proportion of the variance (expressed in partial eta squared) in excess weight 
      attributable to differences in eating habits and physical activity. RESULTS: The 
      prevalence of overweight and obesity was 50.5% in boys and 46.5% in girls. Among 
      boys, moderate and vigorous activities were found to be significantly negatively 
      associated with overweight and obesity (p < .05), whereas in girls, only those 
      with not less than moderate activities were negatively associated with overweight 
      and obesity (p < .05). Sedentary behaviors, time spent watching television, and 
      time spent working on the computer were not significantly associated with obesity 
      in either sex. Consumption of breakfast, vegetables, and fast foods (boys and 
      girls) and potatoes, cakes and doughnuts, and sweets (girls only) was 
      significantly associated with overweight and obesity (p < .05). In general, the 
      partial eta square explained by physical activity was less than 3.6% in boys 
      compared with less than 1.0% in girls, and eating habits explained less than 1.8% 
      in boys compared with 2.5% in girls. CONCLUSIONS: Physical activity explains a 
      greater proportion of variation in body mass index than do eating habits, 
      particularly in boys. Eating habits explain a greater proportion of variation in 
      body mass index than does physical activity in girls. Prospective studies are 
      needed to clarify the relative effects of sedentary behaviors on overweight in 
      adolescents.
