Androgen deprivation therapy (ADT) results in testosterone suppression, a hypothesized mechanism linking ADT to depressive symptoms. This study investigated the relationship between ADT and the risk of subsequently being diagnosed with depressive disorder (DD) during a 3-year follow-up period. The patient sample for this population-based, retrospective cohort study was retrieved from the Taiwan Longitudinal Health Insurance Database 2005. We included all 1714 patients aged over 40 years with a first-time diagnosis of prostate cancer (PC) during 2001 to 2010 who did not have an orchiectomy. Among them, we defined 868 patients who received ADT during the 3-year follow-up period as the study group, and 846 patients who did not receive ADT as the comparison group. The incidence rates of DD per 1000 person-years were 13.9 (95% confidence interval (CI): 9.5∼19.6) and 6.7 (95% CI: 3.7∼11.0), respectively. Cox proportional hazard regressions showed that the adjusted hazard ratio for DD for ADT recipients was 1.93 (95% CI: 1.03∼3.62) relative to the comparison group. This study presents epidemiological evidence of an association between ADT and a subsequent DD diagnosis.
