RESUMO
To study whether poor sleep that is known to characterize methadone maintenance treatment (MMT) patients may be related to their past sexual abuse and/or their treatment modality, we compared perceived sleep indices (Pittsburgh Sleep Quality Index (PSQI); Epworth Sleepiness Scale (ESS)) and depression (21-HAM-D) between women with and without sexual abuse history (Childhood Trauma Questionnaire) in MMT and in a non-MMT ("opioid medication-free") in-patient rehabilitation center (MABAT). Twenty-six sexually abused women in MMT had the worst sleep quality scores (PSQI) (10.4 ± 4.2), followed by 15 sexually abused non-MMT women (7.9 ± 4.8), with the lowest score among 13 MMT non-sexually abused women (6.3 ± 4.8, p = 0.03). ESS score and cognitive state scores (Mini Mental State Exam) were similar. Depression (21-HAM-D) score was similar between the two sexually abused (MABAT and MMT) groups (15.3 ± 7.0 and 15.0 ± 6.3, respectively), but was significantly higher than the nonabused MMT group (10.5 ± 6.3, p = 0.03). Logistic regression model for being poor sleeper (PSQI >5), found depression OR = 1.2 (95% CI: 1.1-1.4, p = 0.001), and poor cognitive state (MMSE) OR = 0.6 (95% CI: 0.3-0.9, p = 0.03) to characterize poor sleep. We conclude that poor sleepers were depressed and this characterized sexually abused women in both the MMT and non-MMT groups.
