Assessment of Quality of Life in Chinese Patients With Inflammatory Bowel Disease and their Caregivers.

Background: Chronic diseases such as inflammatory bowel disease (IBD) usually affect the psychological status and health-related quality of life (HRQOL) of patients and their caregivers. The aim of this study was to evaluate the level of anxiety, depression, and HRQOL and find the risk factors predictive of HRQOL in IBD patients and their caregivers in a Chinese population.

Methods: One hundred four adult patients with IBD, 102 family caregivers, and 99 healthy controls were enrolled. They completed self-administered surveys related to QOL and psychological questionnaires, including the Short Inflammatory Bowel Disease Questionnaire (patients only), the Short Form-36 Health Survey (SF-36), Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS).

Results: Both the mean SAS total score and the mean SDS total score among the patients and the caregivers were found to be significantly higher than those among the general population (P < 0.05). Total SF-36 score was significantly different between the patients and the general population (P = 0.001), and between caregivers and the general population (P = 0.011). The result showed that the total SF-36 score of the patients had a significant negative correlation with SAS score in the patients (P = 0.040), SDS score in the patients (P = 0.004), annual income (P = 0.036), use of biologicals (P = 0.028), frequency of hospitalization in the last year (P = 0.033), and severity of IBD (P = 0.021). The total SF-36 score of the caregivers was significantly and negatively correlated with SDS score in the caregivers (P = 0.010), SDS score in the patients (P = 0.010), use of biologicals (P = 0.013), and frequency of hospitalization in the last year (P = 0.010) of the patients.

Conclusions: A large proportion of IBD patients and their caregivers experience a high level of anxiety and depression and an impaired HRQOL. Higher levels of anxiety and depression, annual income, use of biologicals, higher frequency of hospitalization in the last year, and disease activity were independent predictors of reduced patient HRQOL; higher levels of depression in both caregivers and patients, use of biologicals, and frequency of hospitalization in the last year of the patients were independent predictors of reduced caregiver HRQOL.
