OBJECTIVES: The association of malnutrition with chronic kidney disease (CKD) is well established. However, there is a paucity of studies of the effect of malnutrition risk (MR) on kidney function decline among older persons who do not have end-stage or dialyzable CKD. This study aimed to examine the association between MR status and kidney function, and future risks of kidney function decline and CKD progression in community-dwelling older adults.
DESIGN AND METHODS: Nutrition Screening Initiative's DETERMINE Your Nutritional Health Checklist and estimated glomerular filtration rate (eGFR) were assessed at baseline among 5,122 participants free of end-stage renal failure or dialyzed CKD in the Singapore Longitudinal Aging Studies (SLAS-1 and SLAS-2). Follow-up eGFR was assessed in a subcohort of SLAS-2 participants without CKD (eGFR > 60 mL/min/1.73 m2) at baseline (N = 786) who were followed up at 3-5 years.
RESULTS: In baseline cross-sectional analyses adjusting for other risk factors, low, moderate, and high MR was significantly associated with decreasing eGFR coefficients of -1.5, -3.3, and -5.0 mL/min/1.73 m2 respectively, and increasing CKD odds ratios of 1.81, 2.18, and 3.11 respectively. In longitudinal analysis, low, moderate, and high MR was significantly associated with increased risk of eGFR (>25%) decline (odds ratio of 2.37, 3.34, and 2.18 respectively).
CONCLUSIONS: Among older adults without advanced kidney disease, MR is associated with poor kidney function and increased risk of kidney function decline and CKD. Preventive interventions to modify MR may help to reduce the deterioration of renal function in older people.
