中老年人牙齿缺失与体重指数（BMI）相关性研究

摘要

Objective The aim of this study was to Preliminary discussion on the relevance between teeth missing and Body mass index in elderly.Methods The study sample included middle-aged and old physical examinees belonging to the Xinjiang medical university ifrst afifliated hospital physical examination center. The date were gathered by Questionnaire survey and oral clinical examinition. The outcome variable was the missing teeth number and Posterior occluding pairs(POPs) number. Measure each survey object's height, weight, and calculate the body mass index (BMI).Results There were statistically significant association between the missing teeth number and BMI(b=0.3143,P=0.001). Spearman rank correlation analysis showed that a weak negative correlation between POPs and BMI(r=-0.152,P=0.003).About denture restoration, the Obesity group signiifcantly greater than in the normal group,The difference was statistically signiifcant(P<0.01).Conclusion As the missing teeth number increase or POPs to reduce, BMI index showed a trend of increase,This shows that the teeth in the mouth is missing may affect the BMI index.%目的：初步探讨中老年人牙齿缺失情况与体重指数（Body mass index, BMI）的相关性。方法：以新疆医科大学第一附属医院健康体检中心的中老年体检者为研究对象,对该人群进行问卷调查、口腔检查，记录缺牙数目及后牙咬合对数(Posterior occluding pairs，POPs），测量每位调查对象的身高、体重，并计算BMI。结果：线性回归分析结果显示缺牙数目与BMI指数间存在线性关系(回归系数b=0.3143,P=0.001)；Spearman相关分析显示POPs数目与BMI间呈弱负相关（r=-0.152,P=0.003）。分组研究中肥胖组缺牙后未进行义齿修复的个体所占比例明显大于正常组，差异有统计学意义（P=0.001）。结论：研究人群中随着口腔内缺牙数目增加或后牙咬合对数数目减少，BMI指数呈增大趋势，提示中老年人口腔内牙齿缺失情况可能会影响到BMI指数。
