Social and physical modifications can make aging in place more accessible at the same time they positively impact cognitive function in older adults living alone, finds a new study from the Brown School at Washington University in St. Louis.

"Disabled older individuals living alone were likely to experience a decline in cognitive function over time," said Sojung Park, assistant professor and lead author of the study "Home Environment, Living Alone, and Trajectories of Cognitive Function Among Older Adults With Functional Limitations," published last month in the journal Environment and Behavior.

"However, the detrimental effects of living alone were moderated when the home was equipped with supportive features and accessibility," she said.

Some examples cited in the paper include widening doorways, adding ramps or a first floor bathroom, and installing grab bars and handrails.

The study aimed to investigate the effects of Person-Environment Fit, the degree to which individual and environmental characteristics match, on trajectories of cognitive function.

"Our study is one of the first to examine trajectories of cognitive among functionally vulnerable in the context of the compensating role of home ," Park said.

The researchers used data from Health Retirement Study (1998-2010), focusing on people 65 and above who had at least one limitation in activities of daily living. Using longitudinal mixed-effect modeling, they analyzed the effects of living in supportive home environments on trajectories of cognitive function over time.

The findings reveal the importance of home modifications for socially and physically vulnerable elders, Park said.

"We focus on two areas that have been understudied," she said. "First, most studies on home have not examined to what extent the living arrangements of older adults, such as living alone, affect their health. The physical home environment, including in-home features and accessibility, is more important to older individuals with limited functional ability, but the degree to which these elders can adapt may depend on their living arrangement. This is especially relevant as are known to be important for later year cognitive health and are affected by living arrangements," Park said.

"Second, most existing studies are cross-sectional or followed up for a short period and are limited in their ability to make causal arguments about the benefits of home modifications," she said.

"Our findings reveal the importance of modifications for socially and physically vulnerable elders."
