OBJECTIVE: Improved blood pressure control and use of renin-angiotensin-aldosterone system blockers have altered the clinical presentation or phenotype of chronic kidney disease (CKD) in U.S. adults with diabetes. These changes may influence mortality. RESEARCH DESIGN AND METHODS: Data from the National Health and Nutrition Examination Surveys (NHANES) 1988-2006 were used to examine mortality trends in adults with diabetes, defined as physician diagnosis, fasting glucose gt;/=126 mg/dL, HbA1c gt;6.5% (48 mmol/mol), or use of glucose-lowering medications. Mortality trends by CKD phenotype (estimated glomerular filtration rate [eGFR] and urine albumin-to-creatinine ratio [ACR] level) were obtained via linkage with the National Death Index through 31 December 2011 while accounting for the complex survey design. RESULTS: From 1988 to 2006, adults with an eGFR /=30 mg/g but increased in those with eGFR lt;60 mL/min/1.73 m(2) and an ACR lt;30 mg/g from 35 deaths per 1,000 person-years (95% CI 22, 55) during years 1988-1994 to 51 deaths per 1,000 person-years (95% CI 33, 83) during years 2003-2006. CONCLUSIONS: ACR values are decreasing in U.S. adults with diabetes, but optimal management strategies are needed to reduce mortality in those with a low eGFR and an ACR lt;30 mg/g. |
