介绍卡塔叶 (Catha edulis) 在东非和中东地区广泛使用，通常与吸烟结合使用。睡眠障碍与习惯使用卡塔叶有关。然而，尚未系统地尝试检验阿拉伯茶以及阿拉伯茶与烟草的结合使用与睡眠障碍有关的假设。睡眠障碍与情绪和生理功能失调有关，会增加健康风险。方法我们开发并使用阿拉伯语版本的匹兹堡睡眠质量指数 (PSQI) 在也门进行了一项横断面研究，检查了 151 名同时吸食阿拉伯茶和烟草的人、141 名只吸阿拉伯茶的人和 92 名不吸食阿拉伯茶的人的主观睡眠质量。还收集了主观情绪的测量结果。我们进行了一系列方差分析和 chi(2) 检验，以测试阿拉伯茶和烟草的使用是否与睡眠障碍有关。结果根据 PSQI 总体评分（所有 P 值 < .001）和成分评分评估，同时使用烟草和阿拉伯茶的人和仅使用阿拉伯茶的人比不吸烟的人表现出更大的睡眠障碍。 PSQI 评分与消极和积极情绪相关（所有 P 值 < .004）。 结论 睡眠障碍可能是卡塔叶、烟草和消极健康结果之间联系的机制之一。我们的研究结果可能有助于制定有针对性的预防和减少危害策略，以尽量减少与这些物质相关的医疗保健负担。我们的研究还为阿拉伯语版本的 PSQI 提供了初步支持。
IntroductionKhat (Catha edulis) is widely used in East Africa and the Middle East, often in combination with tobacco smoking. Sleep disturbance has been linked with habitual khat use; however, no systematic attempt has been made to test the hypothesis that use of khat and khat and tobacco in combination are related to sleep disturbance. Sleep disturbances are associated with dysregulations in emotional and physiological functions and can increase health risks.MethodsWe developed and used the Arabic version of the Pittsburgh Sleep Quality Index (PSQI) to conduct a cross-sectional study in Yemen examining subjective sleep quality in 151 concurrent users of khat and tobacco, 141 khat-only users, and 92 nonusers. Measures on subjective mood were also collected. A series of analyses of variance and chi(2) tests were conducted to test whether khat and tobacco use was linked with sleep disturbances.ResultsConcurrent users of tobacco and khat and khat-only users showed greater sleep disturbances than nonusers as assessed by the PSQI global scores (all P values < .001) and component scores. PSQI scores were correlated with negative and positive mood (all P values < .004).ConclusionSleep disturbances may be 1 mechanism of the link between khat, tobacco, and negative health outcomes. Our findings may be useful in developing targeted prevention and harm-reduction strategies to minimize health care burdens associated with these substances. Our study also provides initial support for the Arabic version of PSQI.
