Relationship of Body Composition Parameters with Hip and Fore Arm Bone Mineral Density: An Indian Perspective

Problem statement: The relationship between obesity and osteoporosis has been widely studied and epidemiological evidence shows that obesity is correlated with increased bone mass. Anthropometric factors such as body height and body weight which are related to body mass index should be considered. Approach: We measured whole body fat mass, fat free mass, muscle mass, Body water, percentage fat mass and body mass index in the South Indian women (n = 178, age = 38.34±13.59) by slim manager N-40 (Body Composition Analyzer, Korea). Bone mineral density was measured at right proximal femoral region of 50 South Indian women (n = 50, age = 50.12±13.73) using the device DPX Prodigy DXA Scanner, GELunar, USA. Similarly, Bone mineral density of fore arm was measured using peripheral dual energy x-ray absorptiometry (Osteometer, DTX-200 Ameritech Inc, USA) for 62 (39.76±13.41) women. Results: Body composition parameters such as body water, muscle mass, fat mass and fat free mass exhibited high significance with weight (p<0.001). Trochanter BMD demonstrated high significance with body water, fatfree mass and muscle mass (p<0.01). BMI displayed high significance with body fat mass (p<0.0001). Conclusion: So conclusion of this study depicts that the body composition parameters exhibited significant correlation with right femoral bone mineral density measured at various anatomical sites, but demonstrated no correlation with right fore arm bone mineral density, similarly measured at anatomical sites.
