| Objective: This study aimed to characterize the anthropometric and body composition profile and examine their age-stratified correlations with PA levels in 9- to 12-year-old male students. Methods: A cross-sectional study was conducted on 200 male students (50 per age year from 9 to 12) selected via multi-stage cluster sampling from public schools in Urmia, Iran. Height and weight were measured to calculate Body Mass Index (BMI). Results: Descriptive statistics showed a clear trend of increasing mean values with age for height (127.46±4.52 cm to 143.98±7.93 cm), weight (26.92±3.33 kg to 41.24±6.87 kg), BMI (15.98±3.37 kg/m² to 19.74±5.00 kg/m²), and BF% (11.42±4.11% to 14.92±4.84%). A significant inverse relationship was found between PA level and BMI (p<0.05). Conclusion: While anthropometric measures increase with age as expected, the development of BMI and body composition in 9-12-year-old boys is not a linear process. The stability of BMI and BF% appears to strengthen in the pre-adolescent period (ages 11-12), whereas height and weight remain highly variable. | ||
