Note. BMI = body mass index; CI = confidence interval; HR = hazard ratio. Participants had no history of cancer or heart disease at baseline.
Hazard ratios were stratified by study and adjusted for age, gender, education (high school, some college, college graduate), marital status (married, not married), smoking status (never, former, current), physical activity (low, medium, high), and alcohol consumption (0, > 0 g/day).
