Abstract

Objective Persistent elevation of urinary albumin excretion (UAE), even within normal range, is an independent predictor for cardiovascular disease. Accumulating research suggests that low levels of vitamin D and high levels of parathyroid hormone (PTH) also increase cardiovascular disease risk. This study is intended to investigate the relationship between PTH, vitamin D levels and UAE. Methods We examined 2897 adults aged 50 and above, participating in the second year of the fifth Korea National Health and Nutrition Examination Survey (KNHANES V-2). Anthropometric and laboratory measurements were performed. Elevated UAE was defined as spot urinary albumin creatinine ratio equal or above 10. Results The proportion of elevated UAE (21·8%, 23·2%, 23·2%, 31·8%; P for trend = 0·002) rose with increasing quartiles of PTH. The odds ratio for elevated UAE in the highest quartile of PTH was 72% higher than the lowest quartile group. There was no relationship between vitamin D and elevated UAE. Conclusions Elevated PTH levels are associated with elevated UAE in Korean adults aged 50 and above. Additional studies are needed to clarify this relationship.
