A study published in The Lancet Healthy Longevity analyzed data from over 214,000 adults across 14 countries and regions to examine how modifiable risk factors for dementia vary by location. Researchers found significant differences in the prevalence of these risk factors between high-income and low- or middle-income countries. For example, low educational attainment affected 86% of older adults in China but only 12% in the United States, while high body mass index (BMI) was more common among U.S. participants compared to those in India. Cardiovascular risks like high cholesterol and hypertension were more prevalent in high-income countries, though they were also notably higher in Mexico and Brazil. The study highlights that global patterns exist, such as cardiovascular risks and risky behaviors like smoking and drinking, but local variations suggest that a one-size-fits-all approach to dementia prevention may not be effective.
