Life Satisfaction Linked to Lower Dementia Risk in European Countries

Strategic Insights

— 1 min read

Research from Florida State University College of Medicine suggests that greater life satisfaction is associated with a lower risk of dementia in older adults. The study, which combined data from 15 European countries, found that participants who reported higher life satisfaction levels had a lower risk of developing dementia. The findings, which were published in the journal Age and Ageing, are consistent across sociodemographic groups and European regions.

Key Takeaways:

  • The study examined the prospective association between life satisfaction and dementia risk in samples of older adults from 15 European countries.
  • Participants from the English Longitudinal Study of Ageing (ELSA) and the Survey of Health, Ageing and Retirement in Europe (SHARE) reported their life satisfaction at baseline, which was associated with a lower risk of dementia.
  • The association between life satisfaction and lower dementia risk persisted, accounting for other dementia risk factors, including physical inactivity, smoking, obesity, diabetes, hypertension, and depression.
  • The random-effects meta-analysis (k = 7; total N = 74 392) supported the association between life satisfaction and lower dementia risk.
  • The findings suggest that life satisfaction could be a valuable target for promoting healthier cognitive outcomes in older adults.

Statistics:

  • 6979 participants in the English Longitudinal Study of Ageing (ELSA)
  • 24,098 participants in the Survey of Health, Ageing and Retirement in Europe (SHARE)
  • Female participants accounted for 56.1% in ELSA and 55.8% in SHARE
  • Mean age of participants in ELSA was 65.35 and in SHARE was 64.50
  • Hazard ratio (HR) for dementia risk in ELSA was 0.80 (95% CI = 0.73-0.87)
  • Hazard ratio (HR) for dementia risk in SHARE was 0.82 (95% CI = 0.79-0.86)
  • Total sample size for the random-effects meta-analysis was 74,392 participants
  • Hazard ratio (HR) for dementia risk in the meta-analysis was 0.76 (95% CI = 0.67-0.84)
