AARP was not included in this analysis because the questionnaire did not distinguish between moderate and vigorous-intensity activities.
Models are stratified by cohort, are adjusted for age and are mutually adjusted for both moderate and vigorous-intensity activities.
Models are additionally adjusted for gender (in non-stratified models), smoking (never, former, current, missing), alcohol (none, <15 grams/day, 15–30 grams/day, 30+ grams/day), education (dropout, high school, post high school education, some college, college graduate, post-college, missing), marital status (married, divorced, widowed, single, missing), history of cancer, history of heart disease, and where indicated, body mass index (<18.5, 18.5–25, 25-<30, 30-<35, 35+ kg/m2).
