^aAdjusted for age group and sex

^bAdjusted for age group, sex, race, alcohol consumption, smoking, vegetable consumption, fruit consumption, red meat consumption, current moderate physical activity, current vigorous physical activity, family history of pancreatic cancer

^cAdjusted for the variables in Model 2 with the addition of pancreatitis, diabetes

^dBMI categories 25.0– < 30.0 and ≥ 30.0 were collapsed for the adolescent time period due to small cell sizes when BMI ≥ 30.0 was evaluated alone
