We investigated the relationship between shift work and excessive daytime sleepiness (EDS) among participants in the Japan Nurses' Health Study (JNHS). Responses of 9,728 female nurses to the 6th follow-up questionnaire were cross-sectionally analyzed. EDS was defined as an Epworth Sleepiness Scale score ≥11. EDS-associated factors were evaluated using Poisson regression analysis after adjustment for multiple confounders. Of the participants (mean age, 52.2 ± 8.0 yr), 28.7% were engaged in shift work, and the overall prevalence of EDS was 24.6%. EDS-associated factors were investigated separately in women aged <40 yr (n=250), 40-59 yr (n=7,467), and ≥60 yr (n=2,011). Current engagement in shift work (prevalence ratio: 1.92 [95% confidence interval: 1.20-3.06], compared with no experience of shift work) and obesity (2.08 [1.11-3.88] for BMI ≥30 and 1.39 [1.02-1.90] for BMI of 25.0-30.0, compared with BMI of 18.5-25.0) showed an independent association with EDS in women aged ≥60 yr. The effect of shift work on EDS in female nurses differed by age, as shift work and obesity contributed to EDS only in older participants. Shift work should be assigned after full consideration of age, sleep, and health status to minimize medical errors.
我们调查了日本护士健康研究（JNHS）参与者中轮班工作与日间嗜睡（EDS）之间的关系。对 9728 名女性护士的第 6 次随访问卷的回答进行了横断面分析。EDS 定义为 Epworth 嗜睡量表评分≥11。使用泊松回归分析调整了多个混杂因素后，评估了 EDS 相关因素。在参与者中（平均年龄 52.2±8.0 岁），28.7%从事轮班工作，总体 EDS 患病率为 24.6%。分别在年龄<40 岁（n=250）、40-59 岁（n=7467）和≥60 岁（n=2011）的女性中调查了 EDS 相关因素。当前从事轮班工作（患病率比：1.92[95%置信区间：1.20-3.06]，与无轮班工作经验相比）和肥胖（BMI≥30 为 2.08[1.11-3.88]，BMI 为 25.0-30.0 为 1.39[1.02-1.90]，与 BMI 为 18.5-25.0 相比）与≥60 岁女性的 EDS 呈独立相关。轮班工作对女性护士 EDS 的影响因年龄而异，因为轮班工作和肥胖仅在年龄较大的参与者中导致 EDS。在分配轮班工作时应充分考虑年龄、睡眠和健康状况，以尽量减少医疗错误。
