A Survey on Remaining Teeth and Life-style for prevention of Osteoporosis

为论证牙齿脱落是骨质疏松症的一个简单指标这一假说，对460名当地居民进行了牙齿脱落情况及生活方式调查。大多数受试者是农民。生活方式调查共20个项目，本文对83例来鸟取大学医院就诊的女性骨质疏松症患者进行了骨密度测定，并在数据处理中心用SAS统计软件包进行了数量化理论Ⅰ型方法的分析。在生活方式方面，从问卷调查中揭示出大学生的健康习惯倾向.生活方式与长牙次数的关系在年龄上最为显著.对女性骨质疏松症患者的生活方式与骨密度的关系进行了研究，发现骨密度与剩余牙数的关系不明显，不能作为从大量本地居民中筛选骨质疏松症患者的一个简单指标。

The urpose of this study is to demonstrate the hypothesis that the condition of teeth loss is a simple indicatior finding osteoporosis patients from mass screening of a numberof local residents.The search for ni, ber f remaining teeth and related life-style of local residents(n=460) was conducted. Most of subjects were farmer.

On their life-style it reveals the tendencies of healthy habits from the questionaire.2. The relation beween life-style and numbers of reaining teethis the most siquificant on age.3. The relation between life-style and bone mineral density is defined on female osteoporosis patients.It is cncluded that the relation between bone mineral density and number of remaining teeth has less evident to be a brief indicator for screening osteoporosis patients froma large number of local residents.
