Clinical Epidemiology of Reduced Kidney Function among Elderly Male Fishing and Agricultural Population in Taipei, Taiwan

Purpose. To quantify the prevalence of and associated factors for chronic kidney disease (CKD) among male elderly fishing and agricultural population in Taipei, Taiwan. Methods. Subjects (n = 2, 766) aged 65 years and over voluntarily admitted to a teaching hospital for a physical checkup were collected in 2010. CKD was defined as an estimated glomerular filtration rate <60 mL/min/1.73 m(2). Results. Among these subjects, the over prevalence of chronic kidney disease was 13.6% (95% CI: 12.3-14.9%). The age-specific prevalence of CKD in 65-74 years, 75-84 years, and >= 85 years was 8.2%, 19.1%, and 27.0%, respectively. From the multiple logistic regression, age (OR = 1.05, 95% CI: 1.02-1.09), hyperuricemia (OR = 2.94, 95% CI: 1.90-3.78), central obesity (OR = 1.17, 95% CI: 1.02-1.56), hyperglycemia (OR = 1.23, 95% CI: 1.11-1.67), hypertriglyceridemia (OR = 1.25, 95% CI: 1.08-1.66), and lower HDL-C (OR = 1.61, 95% CI: 1.23-1.92) were statistically significantly related to CKD. The presence of metabolic components (one or two versus none, OR = 1.10, 95% CI: 1.04-1.25; three or more versus none, OR = 2.12, 95% CI: 1.86-2.78) also appeared to be statistically significantly related to CKD after adjustment for other independent factors. Conclusion. Several clinical factors independently affect the development of CKD in the elderly male fishing and agricultural population.
