  • Leisure Activity in Old Age and Risk of Dementia : a 15-Year Prospective Study
  • 2014
  • Ingår i: The journals of gerontology. Series B, Psychological sciences and social sciences. - : Oxford University Press. - 1079-5014 .- 1758-5368. ; 69:4, s. 493-501

    • Objectives. The aim of this study was to investigate whether leisure activity is associated with incident dementia in an older sample.Method. We examined a sample of 1,475 elderly (>= 65 years) who were dementia free at baseline over a follow-up period of up to 15 years. In addition to analyses involving the total time period, separate analyses of three time periods were performed, 1-5, 6-10, and 11-15 years, following baseline measurement of leisure activity.Results. After controlling for a variety of potential confounders, analyses of data for the total time period revealed that higher levels of "Total activity" and "Social activity," but not "Mental activity," were associated with decreased risk of dementia. However, analyses of the separate time periods showed that this association was only significant in the first time period, 1-5 years after baseline.Discussion. The results from this study provide little support for the hypothesis that frequent engagement in leisure activities among elderly serve to protect against dementia diseases across a longer time frame. The finding of a relationship for the first time period, 1-5 years after baseline, could indicate short-term protective effects but could also reflect reverse causality.

  • Loneliness increases the risk of all-cause dementia and Alzheimer's disease
  • 2020
  • Ingår i: The journals of gerontology. Series B, Psychological sciences and social sciences. - : Oxford University Press. - 1079-5014 .- 1758-5368. ; 75:5, s. 919-926
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: To examine the effect of perceived loneliness on the development of dementia (all-cause), Alzheimer's disease (AD), and vascular dementia (VaD).Method: The study comprised 1,905 nondemented participants at baseline, drawn from the longitudinal Betula study in Sweden, with a follow-up time of up to 20 years (mean 11.1 years). Loneliness was measured with a single question: "Do you often feel lonely?".Results: During the follow-up, 428 developed dementia; 221 had AD, 157 had VaD, and 50 had dementia of other subtypes. The entire dementia group is denoted "all-cause dementia". Cox regression models, adjusted for age, gender, and a baseline report of perceived loneliness, showed increased risk of all-cause dementia (hazard ratio [HR] = 1.46, 95% confidence interval [CI] 1.14–1.89), and AD (HR = 1.69, 95% CI 1.20–2.37), but not VaD (HR = 1.34, 95% CI 0.87–2.08). After adjusting for a range of potential confounders, and excluding participants with dementia onset within the first 5 years of baseline (to consider the possibility of reverse causality), the increased risk for the development of all-cause dementia and AD still remained significant (HR = 1.51, 95% CI 1.01–2.25 for all-cause dementia; HR = 2.50, 95% CI 1.44–4.36 for AD).Discussion: The results suggest that perceived loneliness is an important risk factor for all-cause dementia and especially for AD, but not for VaD. These results underscore the importance of paying attention to subjective reports of loneliness among the elderly adults and identifying potential intervention strategies that can reduce loneliness.
