Schizophrenia is a chronic mental disorder associated with significant functional impairment and disability. Sleep disturbances and suicidality are among the common presentations. There is paucity of evidence of any correlation between poor subjective sleep quality and suicidality among patients with schizophrenia in Nigeria. This study aimed to determine the prevalence of poor subjective sleep quality and its association with suicidality among out-patients with schizophrenia.
A cross-sectional study of 153 adult out-patients with schizophrenia. A socio-demographic questionnaire, the Brief Psychiatric Rating Scale (BPRS), the Pittsburgh Sleep Quality Index (PSQI) and suicidality module of the Mini International Neuropsychiatric Interview were administered.
The prevalence of suicidality was 65 (42.5%) while the current prevalence of suicidal ideation and attempts were 54 (34.3%) and n=2 (1.3 %) respectively. One-third of the participants reported poor subjective sleep quality 59 (38.6%). Suicidality was significantly associated with poor subjective sleep quality (aOR 4.13; 95%CI: 1.89-9.01), symptom severity (aOR: 1.08; 95%CI: 1.01-1.15), and being separated or widowed or divorced (aOR: 5.3; 95%CI: 1.78-15.82).
Suicidality is common among outpatients with schizophrenia in Nigeria. Poor subjective sleep quality, symptom severity and marital separation were independently associated with suicidality.
精神分裂症是一种慢性精神障碍，与严重的功能障碍和残疾有关。睡眠障碍和自杀意念是常见的表现。在尼日利亚，精神分裂症患者中，睡眠质量差与自杀意念之间的相关性证据很少。本研究旨在确定尼日利亚门诊精神分裂症患者睡眠质量差的发生率及其与自杀意念的相关性。
对 153 名成年门诊精神分裂症患者进行横断面研究。使用社会人口学问卷、简明精神病评定量表（BPRS）、匹兹堡睡眠质量指数（PSQI）和迷你国际神经精神访谈自杀模块进行评估。
自杀意念的发生率为 65 例（42.5%），当前自杀意念和自杀未遂的发生率分别为 54 例（34.3%）和 n=2（1.3%）。三分之一的参与者报告睡眠质量差，59 例（38.6%）。自杀意念与睡眠质量差（aOR 4.13；95%CI：1.89-9.01）、症状严重程度（aOR：1.08；95%CI：1.01-1.15）和离异（aOR：5.3；95%CI：1.78-15.82）显著相关。
尼日利亚门诊精神分裂症患者自杀意念较为常见。睡眠质量差、症状严重程度和婚姻离异与自杀意念独立相关。
