Risk factors of prostate cancer: a case-control study in Northeast Brazil.

This case-control study aimed on the identification of factors that modified prostate cancer risk of patients in a public hospital of Paraíba. Data from 91 patients with prostate cancer and 91 agematched (±5 years) healthy controls were obtained from medical records and personal interviews. Odds ratios (ORs) and confidence intervals (CIs) were determined using regression analysis. Patients and controls were on average 69.56 (SD= 8.31) and 68.32 (SD= 7.68) years old (p = 0.297). In a model of multiple regression analysis, Afrodescendants and men who ever smoked had a 4.150 and 3.939 times increased risk (p < 0.001; p < 0.001). Family history of first-degree relatives was associated with a 6.967 (p < 0.001) increased risk of prostate cancer. African ancestry, smoking and family history increased the risk of prostate cancer. Recommendations of health authorities regarding prostate cancer screening could stronger focus on men with these risk factors. [ABSTRACT FROM AUTHOR]
