Environmental and psycho-social factors related to prostate cancer risk in the Chinese population: a case-control study / 生物医学与环境科学（英文）

ABSTRACT

<p><b>OBJECTIVE</b>To study the risk environmental and psycho-social factors associated to prostate cancer (PCa) in Chinese population.</p><p><b>METHODS</b>250 PCa patients and 500 controls were enrolled in this case-control study. Information was collected and logistic regression analysis was used to estimate the odds ratios (OR) and 95% confidence intervals (95% CI) for relationship between lifestyle, eating habits and psycho-social factors with PCa risk.</p><p><b>RESULTS</b>Green vegetables and green tea were associated with a decreased risk of PCa (OR=0.39, 95% CI 0.28-0.53; OR=0.59, 95% CI 0.40-0.87, respectively). Family history of PCa (OR=7.16, 95% CI 2.01-25.49), history of prostate diseases (OR=2.28, 95% CI 1.53-3.41), alcohol consumption (OR=1.97, 95% CI 1.33-2.90), red meat consumption (OR=1.74, 95% CI 1.20-2.52), barbecued (OR=2.29, 95% CI 1.11-4.73) or fried (OR=2.35, 95% CI 1.24-4.43) foods were related with increased PCa risk. Negative psycho-social factors including occupational setbacks (OR=1.61, 95% CI 1.00-2.59), marital separation (OR=1.94, 95% CI 1.29-2.91), self-contained suffering (OR=2.37, 95% CI 1.58-3.55), and high sensitivity to the personal comments (OR=1.73, 95% CI 1.18-2.54) were related to PCa.</p><p><b>CONCLUSION</b>Regular consumption of green vegetables and green tea may suggest protective effects on PCa. Alcohol consumption, red meat consumption and barbecued or fried foods were associated with PCa. Negative psycho-social factors may also play a role in the incidence of PCa in Chinese population.</p>
