These variables included: Panel 4 questionnaire mode; number of daily sedentary hours; anxiety; PTSD; alcohol-related problems; current tobacco use (not cigarettes); use of psychiatric medication; history of complementary and alternative medicine treatment; stress of taking care of family; number of lifetime stressful events
