据报道，急性阑尾炎全年都会出现，但某些特定月份的发病率较高。本研究的目的是回顾以往的研究和分析目前的知识和争议有关的季节性变化的急性阑尾炎，检查是否阑尾炎有一个年度的季节性模式。检索了MEDLINE数据库中1970年至2012年期间的英文出版物。这份名单还包括了最近阑尾炎流行病学综述的参考文献。我们选择的研究发表在英语同行评议期刊上，没有干预，进行了至少一年，并有组织学证实的阑尾炎的结果，以及那些暂时报告病例数据的研究。共筛选了30篇标题和摘要的合格性。其中，1970年至2012年在8个国家进行的11项研究符合选择标准，并对系统性综述做出了贡献。在所有国家（除尼日利亚和土耳其外），阑尾炎的季节性模式主要是在夏季出现高峰。阑尾炎在夏季更常见。阑尾炎发病的季节性模式的存在可能是由于暴露于空气污染，减少纤维饮食和夏季胃肠道感染的发病率增加。
Acute appendicitis has been reported to be present throughout the year, but some particular months are associated with higher incidences. The aim of this study was designed to review previous studies and analyze the current knowledge and controversies related to seasonal variability of acute appendicitis, to examine whether appendicitis has an annual seasonal pattern. A search of the MEDLINE databases for English language publications over the period from 1970 to 2012 was conducted. This list was extended by including also references from a recent review of appendicitis epidemiology. We selected the studies, which were published in an English-language peer-reviewed journal, did not have intervention, were conducted for at least one year and had the outcome of histologically-confirmed appendicitis and those which reported case data temporally. A total of 30 titles and abstracts were screened for eligibility. Of these, 11 studies from 8 countries conducted across from 1970 to 2012 met the selection criteria and contributed to the systematic review. A seasonal pattern of appendicitis with a mostly predominant peak is seen during the summer months in all the countries (except Nigeria and Turkey). Appendicitis is more common in summer months. The existence of a seasonal pattern in the onset of appendicitis may be due to exposure to air pollution, decreasing fiber diet and increase in the incidence of gastrointestinal infections in summer.
