Individual and Environmental Determinants of Late-Life Community Disability for Persons Aging With Cardiovascular Disease.

The study is cross-sectional, so it cannot show whether lack of transportation, home modifications, or mobility assistance caused community disability or whether greater disability led to those circumstances. Cardiovascular disease, disability, and environmental factors were self-reported, and the study did not measure cardiac diagnosis, severity, or symptoms such as chest pain or shortness of breath. The environmental variables were limited to what the survey collected, so other barriers such as access to activity venues or neighborhood walkability were not examined. Definitions of social support and social engagement were narrow, so living with people or having a shared space may not reflect actual support or participation. The study was underpowered to fully examine race and disability, and it could not account for the type and severity of other chronic conditions.

The authors reported no conflicts of interest for the authors or for any individuals in control of the article content.

Do not conclude that providing transportation, removing home modifications, or changing mobility assistance would reduce community disability. The study is cross-sectional and self-reported, so it only shows associations, and home-entry modifications may mark greater mobility difficulty rather than cause disability.
