Review of studies on sciatica prevalence and synthesis of available evidence.
To assess the studies on sciatica prevalence, discuss reasons for variation in estimates, provide suggestions for improving accuracy of recording sciatica in epidemiological and outcome studies so as to enable better evaluation of natural history and treatment effect in the presence of low back pain related sciatica.
Sciatica is a common cause of pain and disability. It is more persistent and severe than low back pain, has a less favorable outcome and consumes more health resources. However, sciatica prevalence rates reported in different studies and reviews vary considerably and provide no clear picture about sciatica prevalence.
A literature search of all English language peer reviewed publications was conducted using Medline, EMBASE, and CINAHL for the years 1980-2006. Two reviewers extracted data on sciatica prevalence and definitions from the identified articles.
Of the papers retrieved, 23 were included in the review. Only 2 studies out of the 23 used clinical assessment for assessing sciatic symptoms, and definitions of sciatica varied widely. Sciatica prevalence from different studies ranged from 1.2% to 43%.
Sciatica prevalence estimates vary considerably between studies. This may be due to differences in definitions, methods of data collection and perhaps populations studied. Suggestions are made on how to improve accuracy of capturing sciatica in epidemiological studies.
对坐骨神经痛患病率研究的综述及现有证据的综合分析。
评估坐骨神经痛患病率的研究，探讨估计值差异的原因，为提高流行病学和结局研究中坐骨神经痛记录的准确性提供建议，以便在伴有腰痛相关坐骨神经痛的情况下更好地评估自然病程和治疗效果。
坐骨神经痛是疼痛和残疾的常见原因。它比腰痛更持久、更严重，预后较差，消耗更多的卫生资源。然而，不同研究和综述报告的坐骨神经痛患病率差异很大，无法清晰呈现坐骨神经痛的患病率情况。
使用Medline、EMBASE和CINAHL对1980 - 2006年所有英文同行评审出版物进行文献检索。两名评审员从已识别的文章中提取关于坐骨神经痛患病率和定义的数据。
在检索到的论文中，23篇被纳入综述。23篇研究中只有2篇使用临床评估来评估坐骨神经症状，坐骨神经痛的定义差异很大。不同研究的坐骨神经痛患病率从1.2%到43%不等。
不同研究之间坐骨神经痛患病率的估计差异很大。这可能是由于定义、数据收集方法以及所研究人群的差异所致。针对如何提高流行病学研究中坐骨神经痛的捕获准确性提出了建议。
