Association between caregivers' health-related quality of life and care recipients' health outcomes.

AIMS

This study aimed to investigate the relationship between family caregivers' health-related quality of life and health outcomes in care recipients.

METHODS

A total of 160 female caregivers in Japan were initially assessed using self-reported baseline questionnaires to determine physical and mental aspects of their health-related quality of life. Based on these scores, they were divided into three groups: lower, middle, and higher quality of life. We followed up with the 133 participants (after excluding those that did not respond) 6 years later to assess the health of their care recipients; 36 caregivers continued to provide home care, while 97 reported that their care recipient had died or been admitted into institutionalized care.

RESULTS

Statistically, a higher risk for care recipients' health deterioration was strongly associated with the mental component score in the lower caregivers' quality of life group of than for the middle group, after adjusting for the care recipients' age, health status, and caregivers' age at baseline. There was no significant association between deterioration of health of care recipients and physical component scores of the caregivers.

CONCLUSION

Caregivers' poor health-related quality of life, particularly poor mental health, may be linked to the deterioration of care recipients' health.
