223036 Influences of physical activity and nutrition on cognitive profile of an aging cohortTuesday, November 9, 2010
: 3:15 PM - 3:30 PM
Study Objective: To detect a relationship between physical activity and nutrition on cognitive decline in the elderly.
Background: Physical activity has been proven to enhance cardiovascular endurance, muscle strength, and alertness. It strengthens the heart, lowers blood pressure, reduces LDL and increases HDL, all of which can affect brain functioning. Many studies have also demonstrated a positive relationship between exercise and cognitive function. But this relationship needs to be more clearly elucidated. We chose to investigate the relationship in an Adventist Health Study cohort (AHS-1), which is unique in its dietary and lifestyle habits. This population has a large proportion of vegetarians, non-smokers, and non-alcohol drinkers. This would allow us to better delineate the influence of exercise on cognitive health. Methods: A cohort from the AHS-1 of 500 non-Hispanic White subjects were randomly selected and asked to complete a comprehensive nutrition, lifestyle, and spiritual questionnaire along with a myriad of laboratory studies and neuropsychological tests. Results: A multiple regression analysis will be performed on the relationship between diet, exercise and cognitive function (CVLT). We anticipate an inverse relationship between physical activity and cognitive performance, which would be augmented by a long term vegetarian diet. Discussion: We will attempt to identify nutrients and diet patterns that have an augmenting positive influence along with exercise.
