Prevalence of albuminuria and associated cardiovascular risk factors: A community cohort in Namwon City, Korea.
ABSTRACT To document the prevalence of albuminuria and determine its relationship to risk factors for cardiovascular disease (CVD) among Korean adults.
We performed a cross-sectional study of adults aged 45-74 years from Namwon City, South Korea. Albuminuria was defined as a urinary albumin-to-creatinine ratio (UACR)≥30mg/g. The values of UACR were categorized into 5 groups: <10, 10-19, 20-29, 30-299, and ≥300mg/g. Risk factors for CVD and the estimated glomerular filtration rate (eGFR) were analyzed for an association with UACR values.
Data were obtained from 10,534 participants (4140 men and 6394 women). Albuminuria was more prevalent among women than men (27.3% versus 22.7%, respectively, p<0.001), and it was also more prevalent among older participants (p<0.001). The prevalence of albuminuria was 36.3% among participants with hypertension or type 2 diabetes, and it was 16.6% among participants without these conditions. The UACR was positively associated with CVD risk factors, including blood pressure, obesity indexes, total cholesterol, and the eGFR.
The prevalence of albuminuria is high in the general population in Korea, even among Koreans without CVD risk factors. Lower UACR values are associated with reduced CVD risk factors.

ABSTRACT: These two cohorts were designed to examine the increasing burden of chronic diseases among Korean populations. The studies investigated determinants for stroke, osteoporosis, dementia and cancer among middle-aged and elderly Korean populations. The Namwon Study baseline survey was performed between 2004 and 2007 (n = 10 667), and followed up 4 years later (n = 8157, follow-up rate = 76.5%). The baseline survey of the Dong-gu Study was administered over 2007-2010 (n = 9260), and will be followed up between 2014 and 2015. Questionnaires included assessment of cognitive function, psychiatric health and lifestyle factors. Clinical examinations, biochemical tests and genotyping focused on evaluating the determinants of target diseases and their intermediate phenotypes.
