To determine lifetime prevalence rates of sleep paralysis.
Keyword term searches using "sleep paralysis", "isolated sleep paralysis", or "parasomnia not otherwise specified" were conducted using MEDLINE (1950-present) and PsychINFO (1872-present). English and Spanish language abstracts were reviewed, as were reference lists of identified articles.
Thirty five studies that reported lifetime sleep paralysis rates and described both the assessment procedures and sample utilized were selected.
Weighted percentages were calculated for each study and, when possible, for each reported subsample.
Aggregating across studies (total N=36,533), 7.6% of the general population, 28.3% of students, and 31.9% of psychiatric patients experienced at least one episode of sleep paralysis. Of the psychiatric patients with panic disorder, 34.6% reported lifetime sleep paralysis. Results also suggested that minorities experience lifetime sleep paralysis at higher rates than Caucasians.
Sleep paralysis is relatively common in the general population and more frequent in students and psychiatric patients. Given these prevalence rates, sleep paralysis should be assessed more regularly and uniformly in order to determine its impact on individual functioning and better articulate its relation to psychiatric and other medical conditions.
确定睡眠瘫痪症的终生患病率。
使用“睡眠瘫痪症”、“孤立性睡眠瘫痪症”或“未特指的睡眠障碍”等关键词在 MEDLINE（1950 年至今）和 PsychINFO（1872 年至今）进行了检索。审查了英文和西班牙文摘要，以及已确定文章的参考文献列表。
选择了 35 项报告了终生睡眠瘫痪症发生率的研究，并描述了评估程序和使用的样本。
为每项研究计算了加权百分比，在可能的情况下，还为每个报告的亚样本计算了加权百分比。
汇总各研究结果（总样本量=36533），7.6%的普通人群、28.3%的学生和 31.9%的精神科患者至少经历过一次睡眠瘫痪症发作。在患有惊恐障碍的精神科患者中，有 34.6%报告有过终生睡眠瘫痪症。结果还表明，少数族裔经历终生睡眠瘫痪症的比率高于白种人。
睡眠瘫痪症在普通人群中相对常见，在学生和精神科患者中更为常见。鉴于这些患病率，应更定期和更统一地评估睡眠瘫痪症，以确定其对个体功能的影响，并更好地阐明其与精神科和其他医疗状况的关系。
