Socioeconomic status and microalbuminuria in an Asian population.
BACKGROUND: In studies from developed Western countries, lower socioeconomic status (SES) has been reported to be associated with kidney diseases. However, this hypothesis has not been examined in populations from newly industrialized Asian countries. We evaluated the association between SES and micro/macroalbuminuria in a population-based sample in Singapore. METHODS: We examined 920 participants of Malay ethnicity aged 40-80 years (49.6% female). SES was defined through education, income and housing type of participants. The main outcome of interest was the presence of micro/macroalbuminuria defined as a urinary albumin-to-creatinine ratio (ACR) >or=17 mg/g for men and >or=25 mg/g for women. RESULTS: Lower categories of SES were associated with micro/macroalbuminuria; compared to the higher categories of SES, the odds ratio (95% confidence interval) of micro/macroalbuminuria was 1.76 (1.23-2.52) for primary/lower education, 1.64 (1.16-2.31) for income <1000 Singapore dollars (SGD)/retired status, 1.44 (1.01-2.06) for small/medium housing type and 2.37 (1.56-3.60) for the coexistence of all three low SES factors (primary/ below education, income <1000 SGD/retired status and small/medium housing type) compared to
