Effect of Depression and Antidepressants on Sexual Dysfunction in Men with Diabetes: A National Population-Based Cohort Study.

Abstract

PurposeThis study explored and compared the effects of depression and antidepressants on sexual dysfunction in men with diabetes mellitus (DM).Patients and MethodsPatients older than 18 years who had been newly diagnosed with DM (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 250) between 1999 and 2010 were identified from Taiwan’s National Health Insurance Research Database and were followed up until 2013. Patients with preexisting depression or sexual dysfunction were excluded. A total of 636,210 patients with DM were enrolled. These patients were divided into two groups: DM with comorbid depression and a matched cohort without depression. The groups were followed up until the end of 2010 for the first diagnosis of sexual dysfunction (ICD-9-CM codes 302.70, 302.71, 302.72, 302.74, 302.75, 302.76, 302.79, 607.84, and V417). A Cox proportional hazard model and a Cox regression model with time-dependent covariates were applied.ResultsPatients with DM and depression had a higher risk of sexual dysfunction than those with DM without depression (hazard ratio [HR] = 1.44; 95% confidence interval [CI], 1.33–1.55). The risk of sexual dysfunction was lower in the subgroup who used antidepressants (per 28 cumulative defined daily doses [cDDDs]), HR = 0.96; 95% CI, 0.94–0.97). A significantly lower incidence of sexual dysfunction was also associated with the use of selective serotonin reuptake inhibitors (SSRIs, per 28 cDDD). The adjusted HR was 0.95 (95% CI, 0.93–0.97). Subgroup analysis indicated that SSRI use was significantly associated with an amelioration of erectile dysfunction (per 28 cDDD), with an HR of 0.95 (95% CI, 0.92–0.97).ConclusionMale patients with DM and depression are at increased risk of sexual dysfunction. Antidepressant use had a small inverse association with the risk of sexual dysfunction in men with DM and depression. Antidepressants, in particular SSRIs, did not increase the risk of sexual dysfunction in this population.
