Abstract

BACKGROUND: Quality-of-life is an essential outcome for clinical care. Both chronic kidney disease (CKD) and diabetes have been associated with poorer quality-of-life. The combined impact of having both diseases is less well understood. As diabetes is the most common cause of CKD, it is imperative that we deepen our understanding of their joint impact. METHODS: This was a prospective, longitudinal cohort study of community-based Australians aged ≥25 years who participated in the Australian Diabetes, Obesity and Lifestyle study. Quality-of-life was measured by physical component summary (PCS) and mental component summary sub-scores of the Short Form (36) Health Survey. Univariate and multivariate linear mixed effect regressions were performed. RESULTS: Of the 11 081 participants with quality-of-life measurements at baseline, 1112 had CKD, 1001 had diabetes and of these 271 had both. Of the 1112 with CKD 421 had Stage 1, 314 had Stage 2, 346 had Stage 3 and 31 had Stages 4/5. Adjusted linear mixed effect models showed baseline PCS was lower for those with both CKD and diabetes compared with either disease alone (P < 0.001). Longitudinal analysis demonstrated a more rapid decline in PCS in those with both diseases. CONCLUSIONS: The combination of CKD and diabetes has a powerful adverse impact on quality-of-life, and participants with both diseases had significantly poorer quality-of-life than those with one condition.
