Abstract
BackgroundDespite societal efforts to alleviate the challenges, caregiving seems to constitute a substantial burden and source of stress for many families of older adults in Japan. However, precise information on the physical health of caregivers, based on objective data, is not available. The purpose of this study was to improve the understanding of the physical health of Japanese family caregivers using objective indicators and a comparative research design.MethodsA cross-sectional, comparative study was conducted among family caregivers and their non-caregiver counterparts. Surveyors visited caregivers in their homes to administer a questionnaire survey, measure their blood pressure, and collect blood samples using a kit. Blood samples were tested for LDL-Cholesterol, HDL-Cholesterol, AST, ALT, γ-GTP, uric acid, creatinine and HbA1c. Non-caregiver data were collected at a university-based health checkup center. We compared 149 caregivers with 149 sex- and age-matched non-caregivers using conditional logistic regression analyses to examine the impact of caregiving, adjusting for multiple control variables. Analyses were conducted separately for men and female.ResultsThe prevalence of high blood pressure was significantly higher among caregivers than non-caregivers (male: 72.7% among caregivers vs. 40.9% among non-caregivers, female: 57.1% vs. 27.6%, respectively). After adjusting for related sociodemographic and health factors, high blood pressure remained significantly more prevalent among caregivers than non-caregivers, only among female (adjusted OR=2.16, 95% CI [1.14, 4.08]). Female caregivers showed lower eGFR than their non-caregiver counterparts (adjusted OR=6.54, 95% CI [2.38, 17.91]). No significant differences were observed between the two groups on any other indicators.ConclusionsResults suggest that female caregivers are at a higher risk of conditions such as cerebral, cardiovascular or kidney diseases than non-caregivers. Steps must be taken to identify caregivers with high blood pressure and lowered eGFR and provide them with the support they need before these risk factors develop into serious diseases.

The introduction of the long-term care insurance (LTCI) initiated a transition from family caregiving to socialized caregiving, the original LTCI did not take family caregivers into account; LTCI services were provided only to care recipients based on assessments of their physical and cognitive health, without assessing family caregivers
In this study, we investigated the physical health of family caregivers using objective indicators
Summary
Despite societal efforts to alleviate the challenges, caregiving seems to constitute a substantial burden and source of stress for many families of older adults in Japan. One of the aims of this new insurance system is to help older people live independently In response to this new system, the availability of services increased rapidly, including home-based care services. The introduction of the LTCI initiated a transition from family caregiving to socialized caregiving, the original LTCI did not take family caregivers into account; LTCI services were provided only to care recipients based on assessments of their physical and cognitive health, without assessing family caregivers To address this problem, in the 2006 revision of the LTCI, the Japanese government encouraged each municipal government responsible for managing the LTCI to handle any support programs for family caregivers, such as counseling services. Support for family caregivers has not been as advanced
