Abstract [en]

OBJECTIVES: Improvements in educational attainment, cognitive and sensory functions, and a decline in the prevalence of disabilities have been observed in older adults in Sweden and Denmark. In the present study, it was investigated whether better cognition, higher educational attainment, and improved sensory function among older adults aged 60 and older in these countries have contributed to decreasing rates of old-age disabilities.

METHODS: The analyses were based on repeated cross-sectional data from the Survey of Health, Ageing, and Retirement in Europe, for 2004-2017 period. Descriptive data was used to benchmark the declining prevalence of disabilities, improving cognitive and sensory function, and increased educational level. The association between time and disabilities was analyzed with logistic regression models and the contribution of the improved cognitive, education and sensory function to the declining prevalence of old-age disabilities was estimated using the Karlson-Holm-Breen (KHB) method for mediation analysis.

RESULTS: The analysis suggests that the declining prevalence of old-age disabilities in Sweden and Denmark between 2004 and 2017, can largely be attributed to improved cognitive function and vision, and to a lesser extent by education and hearing ability.

DISCUSSION: These findings raise important questions about the causal mechanisms producing the associations between cognition, education, and sensory functions and disability in older age. Future studies should explore the causal nature of the associations between these mediators, and old-age disabilities. In addition, they should explore whether these findings differ across regional and cultural contexts and over different time periods.
