Abstract
Background and Purpose of Study
Health-related quality of life (HRQOL) affects outcome and survival of end-stage renal disease patients. This study aimed to evaluate the associations between economic, social, psychological factors and HRQOL of hemodialysis (HD) patients in northern Taiwan.
Patients and Study Methods
Patients who had received maintenance HD for at least 2 months at 14 dialysis centers in northern Taiwan were invited to join the study. Demographic, economic, social and psychological data of the patients were collected by questionnaires. Depression status was assessed by the Beck Depression Inventory (BDI). HRQOL was measured by the Medical Outcomes Study Short-Form 36 (SF-36) which consists of eight dimensions, namely physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE) and mental health (MH). These dimensions are further compressed into two scales: the Physical Component Summary (PCS) and the Mental Component Summary (MCS). Simple linear regression analyses were used to evaluate the associations between scores of PCS, MCS, the eight dimensions of the SF-36 and economic, social and psychological variables. Multiple linear regression analyses were used to search for significant associations between HRQOL and variables of interest after adjusting for demographic and clinical factors.
Results
Eight hundred and sixty one HD patients completed the study. There were 373 male (43.32%). The mean age was 59.42 ± 13.18 years (14.77 to 89.33 years). Most of them were married (71.93%). 60.5% of all patients had various degrees of depression. HD patients had lower scores in all eight dimensions of the SF-36 compared with the general population sample in Taiwan. Age was inversely associated with physical function-related QOL dimensions (P<0.01). Divorced patients scored better in PF (P<0.05), BP (P<0.01) and PCS (P<0.05) whereas single patients scored worse in RP (P<0.05) and PCS (P<0.05). Higher monthly income was positively associated with RE, MH and MCS (P<0.01). Increased frequency of joining social activities was positively associated with SF (P<0.05). More things worried was inversely associated with SF (P<0.05), MH (P<0.01) and MCS (P<0.01). Higher BDI scores were strongly inversely associated with lower scores of PCS, MCS and all eight dimensions of the SF-36 (P<0.01).
Conclusion
Higher monthly income and increased frequency of joining social activities are associated with better HRQOL, whereas more things worried and higher BDI scores are associated with worse HRQOL of HD patients.
