Sexual dysfunction in first-episode schizophrenia spectrum disorders

Abstract

Sexual dysfunction (SD) is common in patients with schizophrenia. In this study, we examined the prevalence and correlates of SD in a sample of patients with first-episode schizophrenia spectrum disorders (FES) (n = 77). Sexual functioning was examined using the Arizona Sexual Experiences Scale. Clinical measures of interest included the duration of untreated psychosis, psychopathology, depressive symptoms, functionality, and quality of life. Biochemical testing was also performed to measure prolactin, lipid profiles, and fasting glucose levels. In total, 27 (35%) patients met the criteria for SD, which was significantly more prevalent in females than males (p = 0.027). Higher depression scores, poorer social and occupational functioning, and lower high-density lipoprotein cholesterol levels predicted overall SD. Female sex, more pronounced global psychopathology, and poorer quality of life were also predictors of domain-specific SD, adjusting for the extent of antipsychotic exposure. SD has a high prevalence in patients with FES, particularly females. There is a need for a more nuanced understanding of SD in recent-onset schizophrenia, and to establish its relevance in terms of comorbid depressive symptoms and poor quality of life. SD may require specific attention and tailored treatment in females with FES. • We examined the prevalence and correlates of SD in FES. • SD was assessed in 77 patients with FES using the ASEX. • Female sex and depressive symptoms predicted SD. • Females had worse SD across multiple ASEX domains (1, 2, 4, 5). • FES characteristics were associated with SD in a sex- and domain-specific manner.
