Abstract: (101 Views)
Objective Childhood obesity and under nutrition are emerging public health challenges in many developing countries, including Bangladesh. Accurate assessment of growth and body composition through anthropometric measures is essential for monitoring children's health and guiding effective intervention strategies. This study aims to assess growth status by examining body composition changes using anthropometric measurements in schoolboys aged 12 to 14 years from Jashore, Bangladesh.
Methods The study involved 90 schoolboys aged 12 to 14 years from Jashore, Bangladesh, who were assessed using standardized anthropometric techniques. Skinfold measurement sat the suprailiac, subscapular, and triceps sites were taken using precision calipers for body fat estimation. Considering these measurements, fat mass and lean body mass was calculated.
Results ANOVA results revealed significant age-group differences in triceps, subscapular, and suprailiac skinfold thicknesses, fat percentage, fat mass, and lean body mass (p < 0.01), indicating that body composition varies notably with age. Specifically, 13- and 14-year-olds showed significantly higher skinfold thickness, fat percentage, and fat mass compared to 12-year-olds (p < 0.001). Lean body mass was significantly greater in 14-year-olds compared to both 12- and 13-year-olds (p < 0.001). These findings indicate that fat percentage and lean body mass generally increase progressively with age, reflecting natural developmental changes during early adolescence.
Conclusion This study demonstrates that body composition significantly changes with age among schoolboys aged 12 to 14 in Jashore, Bangladesh. Older boys exhibited higher skinfold thicknesses, fat percentage, and fat mass, alongside a marked increase in lean body mass, indicating a natural progression in physical development during early adolescence. These findings emphasize the value of regular anthropometric measurements for monitoring growth patterns and supporting age-appropriate dietary and medical interventions for school-age children.
