Effects of Lifestyle Factors on Cognition in Minority Population of Older Adults: A Review.

The onset of dementia and Alzheimer's disease (AD) is projected to expand over the next several decades in the United States as the population ages. However, the cognitive health burden is not equally distributed among the population, as Hispanics and African Americans are at higher risk of AD when compared with Non-Hispanic Whites. There is some evidence to indicate that cognitive decline may be associated with lifestyle factors and that interventions in these domains may prevent or delay this decline. These lifestyle factors include social engagement, physical activity, both aerobic and strength training, dietary intake, sleep and stress. This review summarizes, in general, what is known about the relationship between risk factors and cognition and, in particular what is known about this relationship in minority populations. The results show that the relationship between these risk factors and cognitive decline is stronger for some of the factors such as physical activity and dietary intake and weaker for the other factors depending on what is measured and in what populations. It does appear, however, that the studies in minority populations is limited and warrants more targeted research and interventions.

Perceptions, Opinions, Beliefs, and Attitudes About Physical Activity and Exercise in Urban-Community-Residing Older Adults.

Background: This research study illustrates the perceptions, opinions, beliefs, and attitudes of older adults residing in an urban community as major factors to understanding barriers and motivators in older African Americans, Hispanics, and Asians adults within Washington, DC. Methods: Eight focus group sessions conducted with 58 older adults to determine their understanding of physical activity and exercise, as well as of barriers to, motivators for, and benefits of physical activity and exercise. Results: The results showed that dance was the preferred physical activity and exercise, fixed or limited income were the main barriers, and prolonged life, more energy, and a stronger body were the main benefits. Conclusion: The results will assist in recommendations to policy makers on programs for older adults that will increase physical activity and exercise for local citizens. These interventions are more likely to increase older adults' ability to remain in their communities and improve their overall health and well-being.
