摘要:
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。 Abstract: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.
