Trajectories of physical activity, from young adulthood to older adulthood, and pancreatic cancer risk; a population-based case-control study in Ontario, Canada

Table 6 Cumulative life course physical activity score and risk of pancreatic cancer among Cases and Controls from Ontario, Canada

Cumulative life-course physical activity score^a	OR^b (95% CI)	OR^c (95% CI)
Continuous variable	1.00 (1.00, 1.00)	1.00 (0.99, 1.01)
Quartiles
1 (lowest)	1.00	1.00
2	0.96 (0.67, 1.35)	1.13 (0.78, 1.64)
3	0.82 (0.57, 1.17)	0.90 (0.91, 1.31)
4	1.01 (0.71, 1.44)	1.14 (0.77, 1.67)

a. Total cumulative physical activity was derived by multiplying frequency of physical activity per week by the average MET score for the intensity of physical activity; the sum of the intensities at each timepoint was then taken
b. Age group and sex adjusted OR
c. Age group, sex, alcohol consumption, smoking, vegetable consumption, fruit consumption, red meat consumption, family history of pancreatic cancer, race, education adjusted OR
