Do quality of life, participation and environment of older adults differ according to level of activity?
BACKGROUND
Activity limitation is one of the most frequent geriatric clinical syndromes that have significant individual and societal impacts. People living with activity limitations might have fewer opportunities to be satisfied with life or experience happiness, which can have a negative effect on their quality of life. Participation and environment are also important modifiable variables that influence community living and are targeted by health interventions. However, little is known about how quality of life, participation and environment differ according to activity level. This study examines if quality of life, participation (level and satisfaction) and perceived quality of the environment (facilitators or obstacles in the physical or social environment) of community-dwelling older adults differ according to level of activity.


METHODS
A cross-sectional design was used with a convenience sample of 156 older adults (mean age = 73.7; 76.9% women), living at home and having good cognitive functions, recruited according to three levels of activity limitations (none, slight to moderate and moderate to severe). Quality of life was estimated with the Quality of Life Index, participation with the Assessment of Life Habits and environment with the Measure of the Quality of the Environment. Analysis of variance (ANOVA) or Welch F-ratio indicated if the main variables differed according to activity level.


RESULTS
Quality of life and satisfaction with participation were greater with a higher activity level (p < 0.001). However, these differences were clinically significant only between participants without activity limitations and those with moderate to severe activity limitations. When activity level was more limited, participation level was further restricted (p < 0.001) and the physical environment was perceived as having more obstacles (p < 0.001). No differences were observed for facilitators in the physical and social environment or for obstacles in the social environment.


CONCLUSIONS
This study suggests that older adults' participation level and obstacles in the physical environment differ according to level of activity. Quality of life and satisfaction with participation also differ but only when activity level is sufficiently disrupted. The study suggests the importance of looking beyond activity when helping older adults live in the community.
