INTRODUCTION: Despite the high prevalence of sexual dysfunction among male schizophrenia patients, there is still a paucity of research on this area.
AIMS: The study aims to determine the prevalence of sexual dysfunction and any association between male patients with schizophrenia in remission and the sociodemographic profile, medication, depression, anxiety, psychopathology of illness, body mass index, and waist circumference.
METHODS: A cross-sectional study with nonprobability sampling method was conducted in a psychiatric outpatient clinic in Taiping Hospital (Perak, Malaysia) over a 7-month period. A total of 111 remitted male schizophrenia patients were recruited. The validated Malay version of the International Index of Erectile Function (Mal-IIEF-15) was administered to the patients and assessed over 4-week duration in the domains of erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. Logistic regression analysis was employed.
MAIN OUTCOME MEASURES: Prevalence and associated factors for sexual dysfunction in each domain are the main outcome measures.
RESULTS: All five domains of sexual functioning in patients showed a high prevalence of dysfunction ranging from 78.4% to 97.1% with orgasmic dysfunction being the least impaired and intercourse satisfaction the worst impaired. Among the domains, only orgasmic dysfunction was significantly associated with race, i.e., Chinese at lower risk for impairment than the Malays (OR = 0.23; 95% CI: 0.07, 0.76; P = 0.018); education, i.e., patients with education higher than primary level were at higher risk for dysfunction (OR = 6.49; 95% CI: 1.32, 32.05; P = 0.022); and Positive and Negative Syndrome Scale (PANSS)-positive subscale, i.e., higher PANSS-positive score was a protective factor for orgasmic dysfunction (OR = 0.54; 95% CI: 0.33, 0.89; P = 0.015).
CONCLUSIONS: The prevalence of sexual dysfunction was generally high. Malay patients and those with education higher than primary level were at higher risk for orgasmic dysfunction whereas higher PANSS-positive score was protective against the impairment. The high rate of sexual dysfunction in schizophrenia patients warrants a routine inquiry into patients' sexuality and the appropriate problems being addressed.
