  1. Note: Time 1 was 1995–1996, Time 2 was 2004–2005. Chronic conditions included reported history of cardiovascular disease, cancer, renal disease or neurodegenerative conditions (Parkinson’s Diease, Amyotrophic lateral sclerosis or Multiple Sclerosis). Younger individuals were below median age (71.2y at Time 2) and older were greater than or equal to the median age. Nomal-weight was BMI <25 kg/m2 and overweight/obese was greater than or equal to 25 kg/m2
  2. Fully adjusted model: age (yrs), sex (male or female), race (white, black, other, or missing), education (<12 yrs, high school graduate, some college, college graduate, or missing), smoking history (never; quit, <20 cigarettes/d; quit, >20 cigarettes/d; current, <20 cigarettes/d; current, .20 cigarettes/d; or unknown), history of heart disease (yes/no, missing), other chronic conditions (yes/no , missing), depression (yes/no, missing), health status (fair, good, very good or excellent), and change in BMI category from Time 1 to Time 2 (<25, 25– < 30, >30, or missing) and MVPA
