This study investigated the possibility of a relationship between blood pressure level and rotating 3-shift work in a prospective follow-up of workers in a zipper and aluminum sash factory in Japan.
Altogether 1551 men aged 18-49 years were followed prospectively for 5 years, and the cumulative incidence of hypertension among 3-shift workers was compared with that of day workers. A multiple logistic analysis was used for adjusting for base-line characteristics such as age, body mass index, blood pressure, and drinking habit.
In the younger age group, the relative risk of the rotating 3-shift workers during the observational period was increased compared with that of day workers after adjustment for the confounding factors. In the older group, the cumulative incidence of hypertension was not higher for workers who had continued shift work. However, a relatively high risk of hypertension was found for workers who converted from 3-shift work to day work when compared with those who remained on shift work and day work.
It is suggested that there is an association between 3-shift work and blood pressure.
本研究通过对日本一家拉链和铝窗扇工厂的工人进行前瞻性随访，调查血压水平与三班倒工作之间存在关联的可能性。
对1551名年龄在18 - 49岁的男性进行了为期5年的前瞻性随访，并比较了三班倒工人与日班工人的高血压累积发病率。采用多元逻辑分析来调整年龄、体重指数、血压和饮酒习惯等基线特征。
在较年轻的年龄组中，在对混杂因素进行调整后，观察期内三班倒工人的相对风险比日班工人有所增加。在较年长的组中，继续从事轮班工作的工人高血压累积发病率并不更高。然而，与那些继续从事轮班工作和日班工作的工人相比，从三班倒工作转换为日班工作的工人患高血压的风险相对较高。
提示三班倒工作与血压之间存在关联。
