Area of Science:

  • Gerontology
  • Neuroscience
  • Public Health

Background:

  • Sub-Saharan Africa's aging population faces significant healthcare challenges, particularly dementia in rural areas.
  • Dementia prevalence and risk factors remain understudied in rural sub-Saharan Africa.
  • This study focuses on understanding dementia in older adults in rural eastern Uganda.

Purpose of the Study:

  • To determine the prevalence of dementia among older adults in rural eastern Uganda.
  • To identify risk factors associated with dementia in this population.
  • To inform targeted interventions for dementia prevention and management.

Main Methods:

  • A cross-sectional study was conducted in Busia and Namayingo districts, Uganda.
  • Neurocognitive assessments included the Identification and Intervention for Dementia in Elderly Africans (IDEA) and Rowland University Dementia Assessment Scale (RUDAS).
  • Data on depression, alcohol use, and functional abilities were collected; multivariable logistic regression was used for analysis.

Main Results:

  • The study enrolled 602 older adults (mean age 70.0 years, 60.6% female).
  • A prevalence of 20.6% for possible dementia was found using IDEA criteria.
  • Older age (>=70), social isolation, and loneliness were significant risk factors for dementia; primary education and remunerated work were protective.

Conclusions:

  • High prevalence of dementia observed in rural Ugandan older adults.
  • Key risk factors identified include older age, lack of formal education, social isolation, and loneliness.
  • Public health initiatives are crucial for dementia awareness and modifiable risk factor reduction in resource-limited settings.
