Women who report chronic gastrointestinal symptoms compatible with a diagnosis of irritable bowel syndrome (IBS) frequently report sleep disturbances.
The purposes of this study were to (a) compare self-reported and polysomnographic indicators of sleep quality in women with IBS symptoms (IBS-SX, n= 16) and controls (n= 16); (b) examine the relationship between the indicators of sleep quality; and (c) determine the relationship between sleep indicators and psychological distress.
The women slept in a laboratory for 2 consecutive nights. Polysomnographic measurements were recorded during sleep, and a sleep questionnaire was completed upon awakening each morning. Psychological distress was measured with the Symptom Checklist-90-R during the initial interview.
Women in the IBS-SX group reported significantly greater numbers of awakenings during sleep (p = .008) and had a longer latency to REM sleep (p = .04) than did the controls. Self-reported and polysomnographic indicators were more highly correlated in the control group than in the IBS-SX group. In the IBS-SX group, the greater the psychological distress, the less alert (rs = .419) and rested (rs = .564) the women felt in the morning and the more time the women spent in stages 3 and 4 sleep (rs = .479) and less in stage 2 (rs = -.447) and REM (rs = -.414) sleep. In the control group, psychological distress was not significantly associated with self-reported measures but was significantly associated with the number of awakenings (rs = .506) and time in stages 3 and 4 sleep (rs = -.677).
Although the women in the IBS-SX group reported significantly more awakenings, the weak relationship between self-reported and polysomnographic indicators suggests that clinicians must keep in mind that further assessments may be necessary.
报告有与肠易激综合征(IBS)诊断相符的慢性胃肠道症状的女性经常报告有睡眠障碍。
本研究的目的是:(a)比较有IBS症状的女性(IBS-SX,n = 16)和对照组(n = 16)自我报告的睡眠质量指标和多导睡眠图指标;(b)检查睡眠质量指标之间的关系;(c)确定睡眠指标与心理困扰之间的关系。
这些女性在实验室连续睡两晚。睡眠期间记录多导睡眠图测量数据,并且每天早晨醒来时完成一份睡眠问卷。在初次访谈期间用症状自评量表-90-R测量心理困扰。
IBS-SX组的女性报告睡眠期间醒来的次数明显更多(p = .008),并且与对照组相比,快速眼动睡眠潜伏期更长(p = .04)。自我报告的指标与多导睡眠图指标在对照组中比在IBS-SX组中相关性更高。在IBS-SX组中,心理困扰越大,女性在早晨感觉越不清醒(rs = .419)、越没休息好(rs = .564),并且女性在3期和4期睡眠中花费的时间越多(rs = .479),而在2期睡眠(rs = -.447)和快速眼动睡眠(rs = -.414)中花费的时间越少。在对照组中,心理困扰与自我报告的测量指标没有显著关联,但与醒来次数(rs = .506)和3期和4期睡眠中的时间(rs = -.677)显著相关。
尽管IBS-SX组的女性报告醒来次数明显更多,但自我报告的指标与多导睡眠图指标之间的弱关系表明临床医生必须记住可能需要进一步评估。
