Abstract: Objective To investigate the prevalence of chronic kidney disease (CKD) in adults from rural area of Langfang and its related risk factors. Methods A random sample of adults older than 18 years and resident in the rural area of Langfang for more than 6 months was selected by multi- stage cluster sampling method. Clinical data including sex, age, educational level, hypertension, diabetes, blood lipids, uric acid and obesity were compared to assess the risk factors relating to CKD. The positive factors were then analyzed by logistic regression method. Results A total of 18,062 subjects were enrolled in this study, and the prevalence
of CKD was 10.75%. Analysis of the factors relating to CKD showed that female (P=0.000), age (P=0.000), hypertension (P=0.000), diabetes (P=0.000), blood lipids (P=0.021), uric acid (P=0.026) were the influencing factors. Multivariate logistic regression analyses showed that age (OR=1.440, 95% CI 1.732～2.194), hypertension (OR=3.734, 95%CI 2.764～6.423) and diabetes (OR=4.560, 95%CI 2.650～5.850) were the independent influencing factors for CKD patients. Conclusion The prevalence of CKD in adults from rural area of Langfang is higher. Female, hypertension, and diabetes are closely related to the prevalence of CKD. Early preventive measures should be emphasized to improve prognosis of the patients.
