Abstract [en]

Previous studies have shown a decreased risk of prostate cancer for childless men; however, the cause of the association remains to be elucidated. The aim of our study was to assess the risk of prostate cancer by fatherhood status, also considering potential confounding factors. In a case-control study in Prostate Cancer data Base Sweden 2.0, a nationwide, population-based cohort, data on number of children, marital status, education, comorbidity and tumor characteristics obtained through nationwide healthcare registers and demographic databases for 117,328 prostate cancer cases and 562,644 controls, matched on birth year and county of residence, were analyzed. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for prostate cancer overall and by risk category, adjusting for marital status and education. Childless men had a decreased risk of prostate cancer compared to fathers, OR=0.83 (95% CI=0.82-0.84), and risk was lower for low-risk prostate cancer, OR=0.74 (95% CI=0.72-0.77), than for metastatic prostate cancer, OR=0.93 (95% CI=0.90-0.97). Adjustment for marital status and education attenuated the association in the low-risk category, adjusted OR=0.87 (95% CI=0.84-0.91), whereas OR for metastatic cancer remained virtually unchanged, adjusted OR=0.92 (95% CI=0.88-0.96). Our data indicate that the association between fatherhood status and prostate cancer to a large part is due to socioeconomic factors influencing healthcare-seeking behavior including testing of prostate-specific antigen levels.
