老年男性骨质疏松症与发病相关危险因素分析

RISK FACTORS FOR OSTEOPOROSIS IN ELDERLY MEN

探讨老年男性骨质疏松的患病情况与其发病相关危险因素以及防治骨质疏松的策略．采用了与骨质疏松危险因素相关的健康生活方式情况调查表，并应用美国Norland Excellplus双能X线骨密度吸收仪（DEXA）对某干休所离退休的老年男性150名（年龄76．2±8．7岁）进行问卷调查和测定股骨近端各部位骨密度（BMD）值．结果可见：1）髋部BMD测定有骨质疏松者为90名（占60．0％）．60～80岁各组的骨质疏松患病率分别为42．5％，63．9％与71．1％，70及80岁组的骨质疏松患病率明显较60岁增多（P〈0．05；P〈0．01）．2）男性在60岁以后股骨近端各部位骨密度（BMD）测量值逐渐下降，80岁组的股骨颈及Wards三角的BMD下降最明显（P〈0．01）．3）从骨量丢失的部位及程度来看，以股骨Wards三角部最为明显，其次是股骨颈，股骨粗隆部相对较轻．4）骨密度与年龄呈负相关（P〈0．05），与体重指数呈正相关（P〈0．05）．骨质疏松发生与卧床成正相关（P〈0．05）；与适量运动、喝牛奶、服用钙剂成负相关（P〈0．05）．吸烟、饮酒、喝浓茶及日照等因素与骨质疏松的发生未见明显相关．总之，男性老年性骨质疏松的发生率并不低于女性，并受多种因素的影响，如采取健康生活方式，可阻止骨质疏松症的发展和预防骨折的发生．

To analyze prevalence and risk factors for osteoporosis in elderly men military men （150 men aged 66-89, （76.2±8.7） yrs）. A questionaire was conducted to corelate life style and osteoporosis risk factor, proximal femur BMD was measured by dual X-ray absorptiometry. It was found that： 1） Ninety elderly men showed osteoporosis as indicated by BMD in hip （60. 0%）. The prevalence for osteoporosis in 60-80 group was 42.5%, 63.9% and 71.1% respectively,and increased significantly in 70 and 80 years old men than in 60 years old men （P〈0.05; P〈0.01）. 2）BMD declined gradually after 60, the BMD of femoral neck and Ward＇s triangle in 80 years old significantly decreased compared with 60 years old （P〈0.01）. 3）Bone loses in hip was the most severe in Ward＇s triangle, then femoral neck and troach. 4） Age, BMI, milk drinking and exercise influenced hip BMD （P〈0.05）, BMI showed statistically positive correlation with BMD （P〈0.05）, smoking, drinking, tea and sunshine was not related with hip BMD. It was found that proportions of osteoporosis in elder men not lower than female.
