  1. *The χ2 was performed to assess differences in prevalence rates by sex; Student’s t test was performed to assess differences in anthropometric data by sex. Significant P values are indicated in bold font
  2. Percentages are row percentages for prevalence rates by age group; percentages are column percentages for total prevalence rates by sex
