湛江市449例中老年居民跟骨骨密度检测分析

Measurement and Analysis on Calcaneal Bone Mineral Density of 449 Middle and Old Aged Residents in Zhanjiang

[目的]了解湛江市某社区中老年居民跟骨骨矿物质密度(bone mineral density,BMD)(简称骨密度)及随年龄、体表面积(body surface area,BSA)和体质指数(BMI)等的变化规律。[方法]采用跟骨定量超声骨密度仪,测量449例湛江市某社区中老年居民的跟骨骨密度,同时测量其身高和体重。[结果]中老年居民随年龄的增长跟骨骨密度下降;男、女性骨质疏松发生率分别为37.0%和47.6%,女性高于男性;BMD与年龄、身高、体重呈负相关,与BSA呈正相关。[结论]湛江地区中老年居民骨质疏松患病情况为女性较男性严重,年龄、身高、体重和BSA是影响中老年人跟骨骨密度的重要因素。

[Objective] To measure calcaneal bone mineral density（CBMD） among middle and old aged residents in Zhanjiang communities,and to analyze its correlation with age,body surface area（BSA） and body mass index（BMI）.[Methods] CBMD of 449 residents in middle and old ages were measured with CBMD quantitative ultrasonic device,and their heights and weights were measured also.[Results]The CBMD were decreased with aging.The prevalence of osteoporosis in males（37.0%） was lower than in females（47.6%）.CBMD was negatively correlated with age,height and weight,but positively correlated with BSA.[Conclusion]More osteoporosis cases are found in middle and old aged females in Zhanjiang.Age,height,weight and BSA are the main factors of CBMD declination among this population.
