  1. Obesity Status categories were developed using the International Obesity Taskforce estimates that correspond to overweight (25 kg/m2) and obesity (30 kg/m2) at 18 years of age.
  2. a, b refer to the test statistic used to test for significant differences between quartiles.
  3. dSelf-reported physical activity logs were completed by the adolescents, the data reported represent the average minutes spent in the most frequently reported activities for boys and girls.
