上海市某社区老年人跟骨骨密度相关因素探讨

Exploration of the relative factors of the elderly people with the calcaneus bone mineral density in a community in Shanghai

目的:探讨老年人跟骨骨密度(BMD)与性别、年龄、握力的关系,为老年人骨质疏松症预防及干预提供参考。方法:对社区429例60岁以上老年人进行调查,内容包括年龄、性别、右跟骨BMD和双手握力,并进行统计分析。结果 :男性双手平均握力和BMD优于女性(P<0.05);年龄≤70岁组BMD优于>70岁组(P<0.05);握力>28 kg组BMD优于握力≤28 kg组(P<0.05)。结论 :老年男性握力及BMD优于女性;老年人BMD与年龄呈负相关;BMD与双手握力呈正相关。

Objective： To investigate the relationship of the calcaneus bone mineral density of the elderly people with the gender, age and hand grip strength to provide a reference for the prevention and intervention of the osteoporosis of the elderly people. Methods： The survey was done for 429 elderly cases whose age was over 60 years old in the community and the contents of the survey including the age, gender, the right calcaneus bone mineral density and both hand grip strength, and their results were statistically analyzed. Results： The average both hand grip strength and bone mineral density of the male were better than those of the female（P〈0.05）, the bone mineral density in the group ≤70 years old was superior to that in the group 70 years old（P〈0.05）, and the bone mineral density in the group of the hand grip strength 28 kg was superior to that in the group of the hand grip strength ≤28 kg（P〈0.05）. Conclusion： The hand grip strength and bone mineral density of the elderly male were superior to those of the female. The bone mineral density and both hand grip strength of the elderly had the negative correlation to the age and the positive one to the both hand grip strength.
