Sexual dysfunction and associated factors in Thai patients with psychiatric disorders

Sexual dysfunction is common among patients with psychiatric disorders but might be under-reported due to Asian sociocultural factors. Recognition of sexual dysfunction and associated factors in this vulnerable population would help clinicians properly assess and manage related conditions.

We aimed to examine the prevalence of sexual dysfunction and its associated factors among patients with psychiatric disorders in Thailand.

This was a cross-sectional study. We enrolled participants aged 18 and older who visited the psychiatry clinic at King Chulalongkorn Memorial Hospital in Bangkok, Thailand between August 2020 and December 2021. Demographic and clinical data were assessed, and all psychiatric disorders and sexual dysfunctions were diagnosed by clinical interview using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Statistical analysis was done to explore the association between sexual dysfunction and related factors.

Sexual dysfunction was diagnosed in 101 (50.0%) of the total 202 participants. The mean (standard deviation, SD) age was 30.2 (9.0) years, and the majority of patients were men (54.5%), single (81.2%), employed (47.5%) and had a coexisting depressive disorder (48.0%). Multivariable logistic regression analysis showed a significant association between sexual dysfunction and quality of life, unemployment, and the dosage of antidepressants and benzodiazepines.

The prevalence of sexual dysfunction among this population was relatively high. However, the findings may represent only a portion of affected psychiatric patients for others with sexual dysfunction symptoms but without functional impairment did not meet the diagnostic criteria for sexual dysfunction. Improvement of quality of life and optimising antidepressant/benzodiazepine dosage should be further investigated for promoting sexual function in patients with mental disorders.
