Social Activity: Self-reported frequency of participation in 6 items about activities involving social interaction, a higher score indicates more frequent participation; Social Network Size: Self-reported number of children, family, and friends each person had and how often they interacted with them per month Physical Activity: Self-reported frequency of participation in 5 physical activities (hours/week), a higher score indicates more frequent participation. Cognitive Activity: Self reported frequency of participation in 7 cognitive activities, a higher score indicates more frequent participation. Katz Disability: 6 item measures of basic activities of daily living, a higher score indicates greater disability. Global Cognition: Composite measure of cognition based on performances on 18 cognitive tests, a higher score indicates a higher level of cognition. Depressive Symptoms: Modified 10 item CESD scale, a higher score indicates greater depressive symptomatology. BMI: Body mass index: weight in kilograms divided by height in meters squared.
