Hypothesis
Does physical activity reduce the risk of cancer in middle-aged men?
Conclusion
Physical activity, especially at moderately-vigorous or vigorous levels, is associated with a reduced risk of total cancers and specific types of cancer in middle-aged men.
Supporting Evidence
- Cancer incidence data were obtained from death certificates and national cancer registration.
- 969 men developed cancer during the follow-up period.
- Significant reduction in cancer risk was observed only with moderately-vigorous or vigorous physical activity.
Takeaway
If middle-aged men exercise a lot, they are less likely to get cancer.
Methodology
A prospective study examining the relationship between physical activity and cancer incidence over an average follow-up of 18.8 years.
Potential Biases
Self-reported data on physical activity may introduce reporting bias.
Limitations
The study only included men aged 40-59 and did not account for all potential confounding factors.
Participant Demographics
Men aged 40-59 years.
