Higher body mass index (BMI) values have been reported in rotating shift workers compared with regular daytime workers. This study examines the relationship between work schedule and BMI, and considers whether lifestyle habits could explain the relationship.
Japanese female nurses (1179 day workers and 1579 rotating shift workers, aged 20-59) were studied using self-administered questionnaires. The questionnaires assessed height, weight, and dietary intake, physical activity, and sleep (lifestyle) habits.
The BMI of shift workers was significantly higher than that of day workers. Shift workers consumed significantly higher amounts of sugar-sweetened beverages and slept for significantly shorter durations on nights between days on the day shift compared with day workers-factors which were also independently associated with higher BMI. In addition, multivariable linear regression coefficients for BMI showed a significant correlation with rotating shift work (β = 0.051), after controlling for lifestyle habits.
Higher consumption of sugar-sweetened beverages and shorter sleep duration were associated with rotating shift work and higher BMI. This should be taken into consideration in preventing obesity in real-life shift work situations. Other shift work-related factors, such as abnormal timing of meals and/or sleep, should also be identified.
据报道，与正常白班工人相比，轮班工人的体重指数（BMI）更高。本研究探讨工作时间表与BMI之间的关系，并考虑生活方式习惯是否可以解释这种关系。
使用自填问卷对日本女性护士（1179名日班工人和1579名轮班工人，年龄20 - 59岁）进行研究。问卷评估了身高、体重、饮食摄入量、身体活动和睡眠（生活方式）习惯。
轮班工人的BMI显著高于日班工人。与日班工人相比，轮班工人饮用含糖饮料的量显著更高，并且在白班之间的夜晚睡眠时间显著更短，这些因素也与较高的BMI独立相关。此外，在控制生活方式习惯后，BMI的多变量线性回归系数显示与轮班工作存在显著相关性（β = 0.051）。
饮用含糖饮料量较高和睡眠时间较短与轮班工作及较高的BMI相关。在现实生活中的轮班工作情况下预防肥胖时应考虑到这一点。还应确定其他与轮班工作相关的因素，如饮食和/或睡眠时间异常。
