Prevalence of Dementia Risk Factors Varies Across Geographic Settings
A comparative study published in The Lancet Healthy Longevity reveals that while dementia risk factors vary between high-income and low-to-middle-income countries, there are consistent clusters of risk related to cardiovascular health and social factors. The research analyzed data from over 200,000 individuals across 14 countries to identify global patterns in dementia prevalence.
Why it matters
Understanding the global distribution of dementia risk factors is essential for developing targeted public health policies and preventive strategies across diverse economic settings.
HealthDay News - Variation is seen in the prevalence and patterns of risk factors for dementia, but broadly similar clusters of risk factors are observed across countries and regions, according to a study published online July 12 in The Lancet Healthy Longevity .
Emma Nichols, Ph.D., from the University of Southern California in Los Angeles, and colleagues conducted a comparative cross-sectional study using harmonized data from 14 countries and regions, including high-income countries (HICs) and low- and middle-income countries (LMICs). Individuals aged 50 years or older from 11 nationally representative aging studies were included to estimate differences in the prevalence and patterns of 12 established binary dementia risk factors.
