[Effects of sleep quality and mood of patients with Parkinson's disease on their caregivers].

To evaluate the relationship of Parkinson's disease(PD) patients' sleep quality and depression with burden, quality of life, and depression of their caregivers. A total of 120 PD patients (68 males and 52 females) and their caregivers (48 males and 72 females) from Changshu Hospital Affiliated to Nanjing University of Chinese Medicine between January 2017 and June 2019 were recruited. Patients' sleep quality, depression and quality of life was evaluated. Burden, quality of life, quality of sleep, and depression of caregivers were assessed by the Caregivers Burden Questionnaire (CBI), Health Survey Brief (SF-36), Pittsburgh Sleep Quality Index (PQS1) and Hamilton Depression Scale (HAMD), meanwhile, the correlation between relevant factors was analyzed. The CBI of caregivers was positively correlated with the unified Parkinson's disease rating scale (UPDRS)-Ⅲ scores of PD patients (=0.436, <0.05). The CBI, SF-36GH, SF-36MH, HAMD and PSQI scores of caregivers were positively correlated with Parkinson's disease sleep scale (PDSS) scores of PD patients (=0.546, 0.762, 0.528, 0.562 and 0.522, respectively, all <0.01). The caregiver's CBI score was positively correlated with PD patients' Epworth sleepiness score (ESS) score (=0.442, <0.05), and caregiver's CBI, SF-36GH, SF-36MH, HAMD, PSQI scores were positively correlated with PD patients' HAMD scores (=0.765, 0.813, 0.635, 0.884 and 0.601, respectively, all <0.01). The caregiver's CBI score was positively correlated with the PDQ-39 score of PD patients (=0.834, 0.452, 0.463, 0.421 and 0.387, respectively, all <0.05). Multiple regression analysis indicated that the caregiver's CBI score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (=0.512, 0.645 and 0.635, respectively, all <0.01), and the caregiver's SF-36GH score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (=0.452, 0.682 and 0.506, respectively, all <0.01). The caregiver's SF-36MH score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (r=0.426, 0.608 and 0.598, respectively, all <0.01). There was significant correlations between the caregiver's HAMD score and the patient's PDSS and HAMD scores (=0.568 and 0.496, both <0.01), and the PSQI score of the caregiver was significantly correlated with the PDSS and HAMD scores of the patient (=0.532 and 0.461, both <0.01). This current study underscores the presence of a significant relationship of patient's sleep quality with caregiver's burden, quality of life, depression and sleep quality. Specifically, sleep quality and depression of the patients are independent predictors for burden, quality of life and sleep quality of the caregivers.
