Impact of obesity on renal function in elderly Korean adults: a national population-based cohort study.
Background: Obesity is a well-known risk factor for chronic kidney disease and its progression. However, the impact of obesity on the renal function of the elderly population is uncertain. We investigated the association between obesity and renal outcomes in the elderly.
Methods: We analyzed 130,504 participants from the Korean National Health Insurance Service-Senior cohort. Obesity was classified according to body mass index (BMI), sex-specific waist circumference (WC), and the presence of metabolic syndrome. The primary outcome was renal function decline, defined as a decline in the estimated glomerular filtration rate (eGFR) of at least 50% from baseline or new-onset end-stage renal disease.
Results: During a follow-up period of 559,531.1 person-years (median, 4.3 years), 2,486 participants (19.0%; incidence rate of 4.44 per 1,000 person-years) showed renal function decline. A multivariate Cox proportional hazards model revealed that BMI/WC was not associated with renal function decline. However, the group with metabolic syndrome had a significantly increased risk of renal function decline compared to the group without metabolic syndrome (adjusted hazard ratio [HR], 1.24; 95% confidence interval [CI], 1.13-1.36). Compared with the non-metabolic syndrome group, the adjusted HRs (95% CI) for participants with one through five components were 0.96 (0.84-1.11), 1.10 (0.96-1.27), 1.24 (1.06-1.45), 1.37 (1.12-1.66), and 1.99 (1.42-2.79), respectively (p for trend < 0.001).
Conclusion: In elderly Korean adults, metabolic syndrome and the number of its components were associated with a higher risk of renal function decline, but BMI or WC was not significant.
期刊介绍：
Kidney Research and Clinical Practice (formerly The Korean Journal of Nephrology; ISSN 1975-9460, launched in 1982), the official journal of the Korean Society of Nephrology, is an international, peer-reviewed journal published in English. Its ISO abbreviation is Kidney Res Clin Pract. To provide an efficient venue for dissemination of knowledge and discussion of topics related to basic renal science and clinical practice, the journal offers open access (free submission and free access) and considers articles on all aspects of clinical nephrology and hypertension as well as related molecular genetics, anatomy, pathology, physiology, pharmacology, and immunology. In particular, the journal focuses on translational renal research that helps bridging laboratory discovery with the diagnosis and treatment of human kidney disease. Topics covered include basic science with possible clinical applicability and papers on the pathophysiological basis of disease processes of the kidney. Original researches from areas of intervention nephrology or dialysis access are also welcomed. Major article types considered for publication include original research and reviews on current topics of interest. Accepted manuscripts are granted free online open-access immediately after publication, which permits its users to read, download, copy, distribute, print, search, or link to the full texts of its articles to facilitate access to a broad readership. Circulation number of print copies is 1,600.
