Objective To evaluate the impact of depression and life stress on HRQL in the Canadian community dwelling population with PD. Methods A total of 259 respondents from the Canadian Community Health Survey (CCHS 1.1) with self-reported PD were interviewed. Measures included Health Utilities Index Mark 3 (HUI3), Composite International Diagnostic Interview Short Form for Major Depression and a single question regarding the amount of stress in their lives most days. Adjusted HUI3 scores were compared according to depression and life stress using ANCOVA models. Results Respondents without depression had overall HUI3 scores that were 0.29 units higher than respondents with depression [adjusted mean (95% CI) 0.49 (0.39-0.59) vs. 0.20 (0.03-0.37)]. The difference in overall HUI3 scores between respondents who reported high levels of stress as those who did not was 0.19 [adjusted mean (95% CI) 0.42 (0.29-0.55) vs. 0.23 (0.10-0.36)]. Conclusions Substantial impact of depression and life stress, two modifiable factors, on HRQL is seen in PD. HRQL may be improved by clinical management of these nonmotor symptoms in PD.
