A growing body of evidence has implicated caregiving as a risk factor
for health. Extending this research, the article by Schulz and Beach1 in this issue of THE JOURNAL is the first study to
demonstrate that caregiving is a risk factor for mortality, and thus it makes
an important contribution to the broader literature on chronic stress. The
caregivers in their cohort were part of a large population-based study of
the elderly drawn from a random, stratified sample; additional laudable strengths
include the fact that the mortality data controlled for baseline health status
and the careful determination of mortality status for 100% of the sample.
