Abstract

Background: Methadone maintenance has remained the main modality of treatment for opioid dependent subjects. Side effects of methadone treatment may be potential obstacles to its continuation. Sleep quality and sexual function are two culture-based concerns, directly related to patients' compliance with methadone maintenance treatment (MMT) program.

Objectives: This research was conducted to examine the frequency of sleep disparity and sexual dysfunction in patients under MMT referring to MMT clinics of Kerman, Iran.

Patients and methods: In this cross-sectional study, 198 adult subjects under MMT for more than 6 months were enrolled. Measurement tool consisted of Pittsburgh sleep quality index (PSQI), Arizona sexual experience scale (ASEX), the 12-item general health questionnaire (GHQ-12), and a demographic questionnaire. The questionnaires were self-completed, except where individuals were illiterate.

Results: Mean ± SD age of the subjects was 41.2 ± 7.9 years and 93.4% of them were male. More than half of them used heroin. Prevalence of poor sleeping and sexual dysfunction in patients under MMT were 67.7% and 18.2%, respectively. There was no association between sleep quality or sexual dysfunction and demographics or methadone dose. However, a significant correlation was observed between mental health and sleep quality (r =0.16, P = 0.033), and sexual function (r = 0.18, P = 0.011).

Conclusions: Sleep quality showed a poorer profile than sexual function. Therefore, more emphasis should be laid on treatment of sleep disparity during follow up of MMT patients comparing to their sexual function. Patients should be reassured that probable sexual dysfunctions should not be regarded as a consequence of MMT.
