Abstract:

Objective　To investigate the correlation between obesity and periodontitis in middle aged and old population. Methods　The study sample included 381 middle-aged and elderly people from the Physical Examination Center of the First Affiliated Hospital of Xinjiang Medical University；questionnaire survey，general physical examination and oral cavity examination were conducted in them；record the calculus index（CI），bleeding on probing（BOP），periodontal pocket probing depth（PD），clinical attachment loss（CAL），body mass index（BMI）and level of four items of blood lipid tests. Results　The triglyeride level was significantly higher in the obese group（P＜0.05），and the high-density lipoprotein cholesterol level was significantly lower in the obese group（P＜0.05），as compared with normal group. Analysis results showed that BMI was a risk factor for periodontitis（OR＞1，P＜0.05），but there was no obvious correlation between them（P＞0.05）. Calculus index，bleeding on probing and clinical attachment loss were positively correlated with BMI in middle-aged（P＜0.05）. There was no correlation between BMI and periodontal pocket probing depth or attachment loss（P＞0.05）.  Conclusion　Obesity is a risk factor for periodontitis in middle-aged and elderly people，but the correlation between them is still uncertain.

摘要：

目的　探讨中老年人肥胖与牙周炎的相关性。 方法    选取2016年3—5月新疆医科大学第一附属医院健康管理中心的中老年体检者为研究对象，对该人群进行问卷调查，进行身高和体重测定，并行口腔及血脂检查，记录牙石指数（CI）、探针出血（BOP）、牙周袋探诊深度（PD）、临床附着丧失（CAL）、体重指数（BMI）及血脂四项水平。结果　正常、超重及肥胖3组人群中，肥胖组与正常组相比甘油三酯（TG）、血清低密度脂蛋白胆固醇（LDL-C）明显升高，血清高密度脂蛋白胆固醇（HDL-C）明显降低，差异有统计学意义（P＜0.05）；BMI是牙周炎的危险因素（OR＞1，P＜0.05），但两者间不存在相关性（P＞0.05）。中年人BMI与CI、BOP及CAL呈正相关（P＜0.05），老年人BMI与PD、CAL无相关性（P＞0.05）。结论　肥胖是中老年人群牙周炎的一个危险因素，但两者相关性尚不能确定。
