Background: To compare the relationship of the somatometric parameters of the appendicular and axial skeleton with the bone mineral status in ethnically equal Indian group of 1721 years old boys.
Methods: Two hundred and forty one healthy boys had assessments body mass, height, transverse, longitudinal and circumference (Cir) body measurements. Whole body bone mineral density (BMD, g/cm3) and content (BMC, g) were assessed using dual-energy X-ray absorbtiometry (DXA). Pearsons correlation coefficient (CC rx/y) was estimated between mentioned above anthropometric data assessed by the Statistic program software Excell-2007.
Results: In modern young Indian males the BMD reaches 0.94±0.02, the BMC 67.03±1.96, the mean body weight was 64.90±0.74 kg and highly correlated with the body Cir such as chest, gluteal, forearm and thigh Cir (CC rx/y 0.66). Greater body mass was not associated with greater bone mineral content (CC rx/y 0.75, p>0.05). The body height in Indian boys takes 171.33±0.78 cm and has no evident correlations with the rest neither somatometric measurements and BMD or BMC, so stated as the independent body parameter. The upper limbs length directly proportional to the lower limbs length; the length of the tight has the direct proportionality to the pelvic size (CC rx/y 0.580.54) and strong correlation with the BMD (CC rx/y 0.50, p<0.05) and BMC (CC rx/y 0.47, p<0.001). The length of the pelvis also strongly correlates with the BMD (CC rx/y 0.46, p<0.05).
Conclusion: The BMD and BMC significantly associated with the pelvic size, length of the lower limb, but stay independent from the total body parameters as the body weight or height. The BMD and BMC are mostly predicted by the anthropometric parameters of the tubular bones of the limbs.
