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), depression( yes/no, missing), other chronic conditions (yes/no), 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). Television viewing models were adjusted for MVPA (<1, 1–4, >4 h/wk) and MVPA models were adjusted for television (<3, 3–4, 5+ h/day). Time 1 was 1995–1996, Time 2 is 2004-2005
