Abstract:
Modifiable lifestyle factors and body composition can affect the attainment of peak bone mass during childhood. This study performed a cross-sectional analysis of the determinants of bone health among pre-adolescent ( N = 243) Malaysian children with habitually low calcium intakes and vitamin D status in Kuala Lumpur (PREBONE-Kids Study). Methods Body composition, bone mineral density (BMD), and bone mineral content (BMC) at the lumbar spine (LS) and total body (TB) were assessed using dual-energy X-ray absorptiometry (DXA). Calcium intake was assessed using 1-week diet history, MET (metabolic equivalent of task) score using cPAQ physical activity questionnaire, and serum 25(OH) vitamin D using LC-MS/MS. Results The mean calcium intake was 349 ± 180 mg/day and mean serum 25(OH)D level was 43.9 ± 14.5 nmol/L. In boys, lean mass (LM) was a significant predictor of LSBMC (β = 0.539, p 〈 0.001), LSBMD (β = 0.607, p 〈 0.001), TBBMC (β = 0.675, p 〈 0.001) and TBBMD (β = 0.481, p 〈 0.01). Height was a significant predictor of LSBMC (β = 0.346, p 〈 0.001) and TBBMC (β = 0.282, p 〈 0.001) while fat mass (FM) (β = 0.261, p = 0.034) and physical activity measured as MET scores (β = 0.163, p = 0.026) were significant predictors of TBBMD in boys. Among girls, LM was also a significant predictor of LSBMC (β = 0.620, p 〈 0.001), LSBMD (β = 0.700, p 〈 0.001), TBBMC (β = 0.542, p 〈 0.001) and TBBMD (β = 0.747, p 〈 0.001). Calcium intake was a significant predictor of LSBMC (β = 0.102, p = 0.034), TBBMC (β = 0.122, p 〈 0.001) and TBBMD (β = 0.196, p = 0.002) in girls. Conclusions LM was the major determinant of BMC and BMD among pre-adolescent Malaysian children alongside other modifiable lifestyle factors such as physical activity and calcium intake.
