Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Area of Science:

  • Neurology
  • Public Health
  • Gerontology

Background:

  • Mild cognitive impairment (MCI) patients face a high risk of dementia.
  • Social determinants of health (SDH) influence health outcomes and dementia risk in cognitively normal individuals.
  • The impact of SDH on dementia progression in MCI patients remains unclear.

Purpose of the Study:

  • To review evidence on the association between SDH and dementia development in MCI patients.
  • To investigate the role of socioeconomic position in dementia progression.
  • To synthesize findings on SDH and MCI to dementia conversion.

Main Methods:

  • Systematic review of longitudinal cohort studies from PubMed and Web of Science.
  • Included studies with MCI at baseline, dementia outcome, and ≥1 year follow-up.
  • Focused on SDH, particularly socioeconomic position (education, income, race, etc.).

Main Results:

  • 2,082 articles screened; ~20 studies met eligibility criteria.
  • Education showed a small, inconsistent protective effect against MCI to dementia conversion.
  • Preliminary evidence suggests gender/sex does not significantly influence conversion risk.

Conclusions:

  • SDH, especially educational attainment, may influence MCI to dementia progression.
  • Interventions promoting early education could be beneficial.
  • More research is needed to establish causality and understand SDH's role in MCI dementia risk.
