Three years have passed since the countermeasures against the adverse health effects of overwork started in Japan, and fruitful outcomes have been expected. In the current study, a systematic review of articles was performed regarding the association of long working hours (LWH) with cardiovascular diseases (CVD) to obtain recent evidence of their association. An electronic database search was conducted using PubMed among English-written original articles published until December, 2004. A total of twelve articles were found conforming to the study's inclusion criteria, but evidence supporting the association of LWH and CVD was not detected. However, some distinctive studies related to the prevention of CVD were found relating to the concept of sensitive psychosocial factors such as vital exhaustion, and to the statistical modeling of occupational factors and biological indicators with the interaction term of psychosocial factors. Further studies will be needed to clarify the association of LWH and CVD.
日本开始采取措施应对过度劳累对健康的不良影响至今已有三年，人们期待着能取得丰硕成果。在本项研究中，我们对关于长时间工作（LWH）与心血管疾病（CVD）之间关联的文章进行了系统综述，以获取它们之间关联的最新证据。我们利用PubMed对截至2004年12月发表的英文原创文章进行了电子数据库检索。共找到12篇符合该研究纳入标准的文章，但未发现支持LWH与CVD之间存在关联的证据。不过，我们发现了一些与CVD预防相关的独特研究，这些研究涉及诸如精疲力竭等敏感心理社会因素的概念，以及职业因素和生物指标与心理社会因素交互项的统计建模。需要进一步的研究来阐明LWH与CVD之间的关联。
