目的了解上海市北蔡镇老年女性骨质疏松症(OP)与生理因素的关系,为本地区OP的防治提供参考。方法使用美国GE公司的Lunar Prodigy Advance PA+300164型双能X线骨密度仪对398名上海市北蔡镇60～79岁老年女性正位腰椎和左股骨近端进行骨密度测定。结果将老年女性以骨密度测定结果分为:OP组、骨量正常组及骨量减少组,3组对照初潮年龄差异无统计学意义(P>0.05),闭经年龄、行经年限、行经天数、孕次差异有统计学意义(P<0.05);3组两两比较显示:骨量正常组与OP组比较在闭经年龄、行经年限、孕次方面差异有统计学意义(P<0.05),在行经天数方面差异无统计学意义(P>0.05);骨量正常组与骨量减少组比较在闭经年龄、行经年限、行经天数方面差有统计学意义(P<0.05);骨量减少组与OP组比较在闭经年龄、行经天数、孕次方面差异有统计学意义(P<0.05),在行经年限方面差异无统计学意义(P>0.05)。结论上海市北蔡镇老年女性人群OP与女性生理因素密切相关,尤其闭经年龄早、行经年限短、行经天数少、孕次多的老年女性,应注意OP预防。
Objective To understand the relationship between osteoporosis (OP) in elderly women and physiological factors in Beicai town, Shanghai, and to provide reference for the prevention and treatment of OP in this area. Methods The bone mineral density (BMD) of lumbar and proximal femur of 398 elderly women aged 60-79 years in Beicai, Shanghai was measured by GE GE Lunar Prodigy Advance PA + 300164 dual-energy X-ray absorptiometry. Results The results of bone mineral density test in elderly women were divided into three groups: OP group, normal bone mass group and osteopenia group. There was no significant difference in the age of menarche between the three groups (P> 0.05) (P <0.05). The comparison of the two groups showed that the difference between the normal group and the OP group was statistically significant (P <0.05) in the age of amenorrhea, (P> 0.05). There was significant difference between the normal bone mass group and the osteopenia group in the age of amenorrhea, the number of years of treatment and the number of days elapsed (P <0.05), and there was no significant difference between the group of osteopenia There was significant difference between OP group in the age of amenorrhea, the number of menstrual days and the number of pregnancies (P <0.05). There was no significant difference in the years of experience (P> 0.05). Conclusion The elderly female population in Beicai, Shanghai is closely related to female physiological factors. In particular, elderly women with early menarche, short duration of menstruation, few days of menstruation and multiple pregnancies should pay attention to the prevention of OP.
