SUMMARY:

Background: Psychosocial, socioeconomic and sociocultural aspects can influence cognitive function among community-dwelling older adults. Life-space restriction is potentially related to cognitive status. We examined the longitudinal association between life-space mobility and changes in cognitive function in community-dwelling older adults in different social settings of North and South America and Europe. Methods: We used data from 1486 participants of the International Mobility in Aging Study (IMIAS) conducted at five sites: Tirana (Albania), Natal (Brazil), Manizales (Colombia), Kingston and Saint-Hyacinthe (Canada). The IMIAS study methodology has been previously described (Gomez, 2018). Central tendency and dispersion measures were used to describe the sample at the baseline and in the segment. To analyze the relationship between cognition and the use of living space, quantile regression (RQ) was used. The analysis evaluated factors related to cognitive function in 2016, by adjusting the score obtained in 2012. For this analysis, two models were made: an initial model with socioeconomic characteristics, living arrangements and social support; and a second model with the same previous variables adding measures of physical performance, depressive symptoms and chronic conditions (group of clinical variables). The use of living space was assessed using the Life-Space Assessment (LSA), applied at the baseline (2012) and the Leganés Cognitive Test (PCL) was used to assess the cognitive function at the baseline and at the follow- up (2016). Results: Women had a more restricted use of living space than men (p <0.001), and these gender differences were present in all research sites. The gender difference becomes even more evident than in the boundary categories (categories I and V). A larger number of women were classified in category I (p <0.001) and this gender difference was greater in Natal, Manizales and Saint-Hyacinthe. Results: A decrease in the cognitive function was observed at all research sites, except in Manizales. Participants with more restricted life-space at baseline had a decrease in their cognitive function 4 years later (β=-0.79, 95% CI: -1.400 to -0.18, p-value<0.01) compared to those with the highest level. This decrease was independent of gender, age, research site, education, income sufficiency, social support, depression, cognitive function at baseline, chronic conditions and physical performance. Conclusions: Restriction in life-space is an important prognostic factor for cognitive function. Maintaining life-space can be a goal in public policies aimed at encouraging healthy aging, and might be useful in clinical practice to promote health status and to monitor older people at higher risk of cognitive decline.
