Hypothesis
Are socio-economic and lifestyle factors associated with the risk of prostate cancer?
Conclusion
High socio-economic status is associated with increased risk of prostate cancer, and divorced or separated men might be at higher risk than married men.
Supporting Evidence
- During a mean follow-up of 9.3 years, 644 cases of prostate cancer were diagnosed.
- Risk was elevated among men in occupations of high socio-economic status (RR = 1.30).
- Men with high education had a higher risk compared to the least educated (RR = 1.56).
- Divorced or separated men showed a higher risk compared to married men (RR = 1.56).
- There was a weak negative association with leisure-time physical activity (RR = 0.80).
- There was a weak positive association with increasing number of cigarettes (P = 0.046).
- Alcohol consumption was not related to the risk of prostate cancer.
Takeaway
This study found that men with higher education and better jobs are more likely to get prostate cancer, and being divorced might also increase the risk.
