Abstract:
Objective To study the relationship between periodontitis and chronic kidney disease (CKD) among Uygur adults of Xinjiang. Methods Data of 1650 Uygur adult residents (age＞18 years) in the Moyu county, Xinjiang were analyzed. The subjects were sampled randomly with stratify capacity from 15 villages among 364 villages. All the subjects received the questionnaire and the oral examination. The markers and risk factors of chronic renal injury were inspected. The subjects were categorized as periodontitis group and non-periodontitis group according to chronic periodontitis diagnostic criteria. The periodontitis group was further divided into mild, moderate and severe periodontitis. Results The data of 1415 subjects were completed. The prevalence of chronic periodontitis was 65.2% (95%CI:65.0-65.4). The prevalence of CKD was 5.2% (95%CI:5.1-5.3). Albuminuria was found in 4.2% (95%CI:4.1-4.3) of subjects. 1.3%(95%CI:1.3-1.4) of individuals had renal insufficiency. In periodontitis group, the prevalence of CKD was 6.4%, which was higher than that in non-periodontitis group 2.9% (χ2=7.841 ,P=0.005).Univariate regression analysis showed that severe periodontitis was risk factor of CKD (OR =3.2,95% CI:2.0-5.2). Multivariate logistic regression analysis showed that severe periodontitis was independently associated with CKD (OR = 1.9, 95%CI: 1.1-3.3). Conclusions In Uygur adults of rural area of Xinjiang, the prevalence of CKD is higher in periodontitis group as compared to non-periodontitis group. Severe periodontitis is an independent risk factor of CKD.
