Bone Abstracts

Objectives: To establish the average bone mineral density (BMD) and bone mineral content (BMC) in young male population from the different ethno-geographical groups

Materials and methods: Estimations of the calcaneal BMD (g/cm²) and BMC (r), using on ALOKA-5.0 DXA machine among Indian (n=58) and Nigerian (n=72) male students (17–20 years), were done. The anthropometric program included body weight, height, shoulder and thorax width, triceps, biceps, suprailiac and calf skinfold measurements among Ukrainian (n=200), Indian (n=84) and Nigerian (n=97) male students (18–21 years). Total body fat percentage was calculated by the Mateigka (1921) equation, total body muscular mass by the Kuczmarski R.J, Flegal K.M. Default (2000).

Results: Obtained data reveal that the Ukrainians and Nigerians have mostly similar BMD and BMC: BMD 1.05±0.04 in Ukrainians, 1.05±0.02 in Nigerians; BMC 77.40±4.49 in Ukrainians, 77.32±2.21 in Nigerians. Indians have the lowest BMD and BMC among compared groups: BMD 0.94±0.02, BMC 67.09±1.96, which are significaly (10.35% for the BMD and 13.40% for the BMC, P< 0.001) lower, than in Ukrainians and Nigerians. Anthropometric data reveal the highest body parameters of the weight (74.58±1.95 kg), height (173.58±0.92 cm), shoulder and thorax width and lean muscular body mass (52.12±1.58 kg). Ukrainians show the lowest weight (55.53±0.69 kg), height (166.06±0.57 cm), thorax width, moderate muscular mass (46.08±1.5) and highest thickness of the skinfolds and body fat (16.54±0.52%). Indians expose the moderate weight (63.89±1.25 kg), height (169.16±1.05 cm), fat percentage; thorax width was same as that in Nigerians, but the muscular mass was lowest (45.78±3.30 kg) among participants.

Conclusions: BMD, BMC and anthropometric parameters have obvious ethno-geographical features.
