Although poorer self-rated health (SRH) is associated with increased mortality, less is known about its impact on functioning. This study evaluated whether poorer SRH was associated with decline in walking speed and whether caregiving, often considered an indicator of chronic stress, modified this relation. The sample included 891 older US women from the Caregiver-Study of Osteoporotic Fractures. SRH was assessed at the baseline Caregiver-Study of Osteoporotic Fractures interview, conducted in 1999-2001, and was categorized as fair/poor or excellent/good. Rapid walking speed over 2,3, or 6 m was measured at baseline and 2 annual follow-up interviews. Respondents with fair/poor SRH walked significantly slower at baseline than those with excellent/good health (mean=0.8 (standard deviation, 0.3) vs. 1.0 (standard deviation, 0.3) m/second, P
