摘要
目的:调查深圳市正常体质量指数人群骨密度和峰值骨密度(PBD),以期为深圳地区骨质疏松症防治工作提供理论依据.方法:近5 a体检的健康成年677名,年龄20以上,男女性均以5岁一个年龄段分为14组;双能X光骨密度仪测量骨密度.结果:男性各部位PBD值出现在25~岁,女性各腰椎PBD值出现在35~岁,髋部PBD值出现在40~岁.在80~岁年龄段,男性腰椎骨密度出现高于其PBD的另一个峰值,女性骨密度自45~岁年龄段后随年龄逐年下降.结论:女性PBD形成晚于男性而接近绝经期;其骨密度自45岁年龄段迅速减低,而男性则发生在65岁年龄段;骨质疏松的预防应从青少年时期提高PBD开始.
AIM:To investigate the bone density and peak bone density(PBD)in healthy residents with normal body mass index in Shenzhen City for the prevention of osteoporosis in Shenzhen.METHODS:Bone mineral density of 677 healthy residents,who were aged over 20 and has lived in Shenzhen for more than l0 years,was measured by dual-energy X-ray absorption-metry(DEXA).The subjects were divided into 14 age groups with five years in each group.RESULTS:The PBD of lumbar vertebral and femoral neck and ward's triangle was observed in 25-29 male group and in 35-39 female group and the PBD of neck and ward's triangle was observed in female 40-44 group.The highest bone mass density was found in 80-84 male group.The bone mass density dropped rapidly from 45 years on in females.CONCLUSION:Female PBD appears later than male PBD,just before menopause.The PBD in female is drops rapidly from 45 years on,while that in males drops from the age of 65 or 70.Prevention of osteoporosis should starts with the elevation of PBD in adolescents.
