Prevalence and factors associated with caregiver burden in caregivers of elderly dependents in San Pa Tong District, Chiang Mai
Objectives To study the prevalence of and factors associated with caregiver burden in caregivers of elderly dependents.
Methods A cross-sectional study was conducted using questionnaires to collect data from caregivers of elderly dependents [age ≥ 60] in San Pa Tong District, Chiang Mai, Thailand between February-July 2020. The questionnaires included general demographic data of the caregivers and their elderly dependents plus the Zarit Burden Inventory (ZBI), the Pittsburg Sleep Quality Index (PSQI) and the Patient Health Questionnaire-9 (PHQ-9). Multivariable logistic regression analysis was used to examine the association between factors and caregiver burden.
Results A total of 136 pairs of caregivers and their dependent elderly patients were included in the study. The prevalence of caregiver burden was 80.15%, divided into low to moderate (38.24%), moderate to severe (38.97%) and severe (2.94%). The Mean ZBI score was 34.65 ± 15.51. There was a statistically significant association between poor sleep quality of the caregivers and caregiver burden. Caregivers with poor sleep quality were 8.87 times more likely to have caregiver burden than caregivers with good sleep quality (95%CI = 1.32 - 59.52, p = 0.02). In addition, caretakers of patients whose dependence was due to neurological disease were 5.21 times more likely to have caregiver burden than those of patients without neurological disease. The difference approached statistical significance (95%CI = 0.94 - 28.78, p = 0.05).
Conclusions Caregiver burden in caregivers of dependent elderly patients is common and is significantly associated with poor sleep quality in caregivers, particularly where the cause of dependence is neurological. Screening for caregiver burden and sleep quality should be performed for caregivers of elderly dependents.
