Abstract:

Objective To explore the differences of bone mineral density as well as prevalence of osteoporosis(POP) and their changes with age in Maonan, Mulam, Yao and Hmong females adults in Guangxi. Methods Totally 860 female volunteers from Maonan, Mulam, Yao and Hmong in Guangxi province were enrolled in this study, and bone mineral density was measured via quantitative ultrasonic bone densitometer on right calcaneus of participants. Results Obvious statistic differences of bone quality index(BQI), T-score and POP were not noticed among Maonan, Mulam and Hmong women but were found between Yao and the other three ethnicities (P<0.05). With aging, value of bone mineral density decreases markedly from its peak in age 35-45 group in Yao and Maonan. And value of bone mineral density in Mulam and Hmong keeps steady prior to age 45 years while declines sharply after age 45 years. And in age 45-55 group, BQI and T-scoreof Yao females were significantly higher than that of Maonan, Mulam and Hmong females (P<0.05). Furthermore, in age 45-55 group, the POP of Yao women was pronouncedly lower than that of Maonan, Mulam and Hmong women but no differences revealed among Maonan, Mulam and Hmong women. Conclusion The differences of bone mineral density and POP were noticed remarkably in different ethnic women in Guangxi, and Yao women showed the best bone quality among four minorities.
