A longitudinal study on public policy and the health of in-house caregivers in Europe.

Caregiving has negative effects on the health of informal caregivers. The current aging of the population predicts an increase in the number of informal caregivers worldwide. The effect of available public policies that support informal caregivers in their self-perceived health is an understudied topic. We analyzed the differences in the effects of public support policies in 11 European countries using longitudinal data from waves 5 and 6 of the Survey of Health Ageing and Retirement in Europe. In this cohort, 2303 respondents were in-house informal caregivers. Logistic regression models were fitted adjusting for the main determinants of caregiving. Respite care and caregiver allowances emerged as the most effective measures of support for caregivers' health maintenance (relative risk [RR] = 0.2; 95 % CI = 0.1-0.8 and RR = 0.5; 95 % CI = 0.3-0.9). Despite the differences in the welfare systems of Scandinavian and Mediterranean countries, informal caregivers in these countries were less likely than those living in Continental or Eastern countries to have declined health two years later. Our results indicate that public support policies are significantly related to caregivers' subsequent health, but the effects vary by country. Country-specific studies should be performed to take into account the determinants of caregiving linked to the social context of each country.
