云南省西双版纳地区成人慢性肾脏病流行病学调查

目的 了解我国云南省西双版纳少数民族地区成人慢性肾脏病(CKD)患病率及危险因素.方法 对该地区20岁以上常住居民进行随机分层抽样,留取晨尿,分别采用尿白蛋白,肌酐比值方法检测白蛋白尿发生率(≥30 mg/g为阳性);干化学法结合尿离心后显微镜检查法检测血尿发生率(≥3红细胞/高倍视野为阳性);以中国人简化MDRD公式计算估计肾小球滤过率(eGFR)低于60 ml·min-1·(1.73m2)-1者为eGFR异常].检测CKD相关危险因素指标.结果 符合入选条件的被调查者共5566例,白蛋白尿阳性率为8.06%;血尿阳性率为4.01%;eGFR低于60 ml·min-1(1.73 m2)-1者为2.89%;去除白蛋白尿、血尿及eGFR下降共同存在造成的重复.该地区CKD患病率为12.53%.性别、年龄、民族以及相关危险因素分层后比较结果与多因素Logistic回归分析结果一致,年龄增加、血压升高、空腹血糖升高及三酰甘油升高与白蛋白尿独立相关;年龄增加、收缩压升高与肾功能下降独立相关;年龄增加与血尿独立相关.结论 云南省西双版纳地区成人CKD患病率为12.53%,相关危险因素包括年龄增加、高血压、血糖及血脂异常.

Epidemiological investigation of adult chronic kidney disease in the Xishuangbanna district of Yunnan province

Objective To investigate the prevalence and risk factors of adult chronic kidney disease (CKD) in the Xishuangbanna district of Yunnan province with a big population of minorities. Methods Residents aged 20 years and older in the area of Xishuangbannan were randomly selected by using a stratified, multi-stage sampling method. All the residents were tested for morning spot urine of albumin tO creatinine ratio (ACR) (abnormal≥ 30 mg/g); morning spot urine dipstick of hematufia (abnormal 1+ or greater) was confirmed by urine microscopy (abnormal ＞ 3 red blood cells/HP); and modified simplified MDRD equation for Chinese adult was applied to characteristics, health characteristics (e.g. hyperglycemia, hyperlipidemia and hypertension) and indicators of kidney damage were also examined. Results Eligible data of 5566 subjects were included in the study. The prevalence of albuminuria was 8.06%, hematuria was 4.01% and reduced eGFR was 2.89%. Apart from the repetition among microalbuminuria, hematuria and reduced eGFR, approximately 12.53% subjects had at least one indicator of kidney damage. The prevalence of CKD in stratified subgroups with age, gender, nations and CKD risk factors was coincidence with the Logistic regression results. Age increase, hypertension, byperlipidemia and fasting plasma glucose increase were independently associated with albuminuria; age increase, hypertension were independently associated with reduced renal function; age increase was independently associated with hematouria. Conclusions The prevalence of adult chronic kidney disease is 12.53% in the Xishuangbanna district of Yunnan province. Independent risk factors associated with kidney damage are age, hyperglycemia, hyperlipidemia and hypertension.
