Women on hemodialysis have lower self-reported health-related quality of life scores but better survival than men

Abstract

BACKGROUND: Hemodialysis patients suffer from poor quality of life and survival. A retrospective cohort study was performed to examine the sex differences in self-reported quality of life and mortality in a Taiwanese hemodialysis cohort. METHODS: A total of 816 stable hemodialysis patients were included. Patients completed two questionnaires: the 36-item Short Form Health Survey Questionnaire (SF-36, Taiwan Standard Version 1.0) to assess health-related quality of life (HRQoL) and the Beck Depression Inventory (BDI, Chinese Version) to assess depressive mood. Mortality outcomes were recorded for a seven-year follow-up period. RESULTS: After adjustment for confounding factors, women had significantly higher BDI scores (P=.003), lower physical functioning (P<.001), bodily pain (P<.001), mental health (P=0007), and physical component scale (PCS) scores (P<.001). There were 284 deaths recorded. In the Cox-proportional hazard model, women had significantly lower mortality than men (P<.001). CONCLUSIONS: Women on hemodialysis had more depression-related symptoms and poor self-reported HRQoL, but better survival than men. The sex difference in psychological and HRQoL issues deserves greater concern because this relates to clinical care and further study.
