Objective To explore the periodontitis in middle-aged and aged overweight-obese people,and to determine its correlation with serum lipids,serum glucose.Methods Ninety-six cases were in the overweight group while 71 cases were in the obesity group.To compare waist circumference (WC),body mass index (BMI),fasting glucose( FPG),total cholesterol (TC),triglycerides (TG),high density lipoprotein ( HDL),low density lipoprotein (LDL),periodontal probing depth(PD),clinical attachment loss(CAL) and bleeding index(BI) between two groups. Results The body weight,height,WC and BMI of obesity group were significantly larger than those of overweight group (P <0.05).There was no significant difference in serum glucose,serum lipids,PD,CAL and BI between obesity group and overweight group(P >0.05).Thirty-one cases(32.29%) of periodontitis were confirmed in the overweight group while 19 cases(26.76%) in the obesity group,there was no significant difference in detection rate of periodontitis between two groups (P >0.05).BI positively correlated with HDL(P <0.05),PD negatively correlated with TC and LDL (P <0.05),CAL negatively correlated with body weight and TC(P <0.05),height negatively correlated with TC and HDL (P <0.05),and BMI positively correlated with FPG(P <0.05).Conclusion Periodontits closely correlates with serum lipids and body weight,which suggests that the disorders of serum lipids and body weight might be the risk factors for chronic periodontits . Further study on the relationship between periondtitis and obesity is necessary .%目的：探讨中老年超重及肥胖患者牙周状况及其与血糖、血脂的相关性。方法超重组96例，肥胖组71例，对比两组腰围（WC）、体重指数（BMI），空腹血糖（FPG）、总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白（HDL）、低密度脂蛋白（LDL），牙周探诊深度（PD）及附着丧失（CAL）、出血指数（BI）。结果肥胖组体重、腰围、BMI 均明显大于超重组（P ＜0．05）；两组血糖、血脂、PD、CAL、BI 比较，差异均无统计学意义（P ＞0．05）。超重组确诊牙周炎31例（32．29％），肥胖组确诊牙周炎19例（26．76％），两组牙周炎检出率比较，差异无统计学意义（P ＞0．05）。 BI 与 HDL 呈负相关关系（P ＜0．05），PD 与 TC 和 LDL 呈负相关关系（P ＜0．05）；CAL 与体重、TC 呈负相关关系（P ＜0．05）；身高与 TC、HDL 呈负相关关系（P ＜0．05），BMI 与 FPG 呈正相关关系（P ＜0．05）。结论牙周炎与血脂、体重关系密切，提示血脂、体重异常可能是患慢性牙周炎的危险因素，但肥胖与牙周状况的关系还需进一步探讨。
