摘　　要：目的：探讨绝经后骨质疏松症的发病情况。方法：采用双能Ｘ线骨密度仪测定了３００例绝经后妇女腰椎正侧位骨密度，年龄４２～７２岁，平均年龄５６．３８岁。结果：诊断为骨质疏松者１２３ 例，占４１％ ，骨质疏松病人随年龄增长而增加，４０岁年龄组与５０岁年龄组比较无差异（Ｐ＞ ０．０５），而以上２组分别与６０岁以上年龄组比较有显著性差异（Ｐ＜ ０．０１）。骨质疏松患病率还随绝经年限增长而增加，绝经５ 年以下者患病率无显著差异（Ｐ＞ ０．０５），绝经５ 年以上者患病率明显增高（Ｐ＜ ０．００５）。结论：绝经后骨质疏松症在６０ 岁以后或绝经５年以上明显增加。Objective:To explore the incidence of postmeopausal osteoporosis.Methods:The bone mineral density of lumbar spine was achieved in 300 postmenopausal samples (The age ranged from 42 to 72 year,mean 56.38 years)by Dual energy X-ray obsorptiometry.Results:osteoporosis was diagnosed in 132 cases(41%).The incidence of this disease was increased with age but no differences were found belween 40 age-group and 50 age-group(p>0.05).Howerve the significant differences was existed between above two groups respectively and 60 years age-group(p<0.01).The incidence was also increases with the duration of postmenopausal,there was no difference among those whose duration were less than 5 years(p>0.05),but the significant difference was existed among those whose durations were more than 5 years(p<0.005).Conclusion:The incidence of postmenopausal osteoporosis is obviously increased after 60 years old or postmenopause longer than 5 years.
