【摘要】 目的 了解送餐平台外卖员长工时现况，分析其对职业紧张、抑郁症状、失眠症状、疲劳蓄积和生活满意度等早期健康效应的影响。方法 采用方便抽样方法，选择广州市内2家送餐平台的2 145名外卖员为研究对象，采用《职业紧张测量核心量表》《患者健康问卷抑郁症状量表》《自我睡眠管理问卷》《劳动者的疲劳蓄积度自己诊断调查表》《世界卫生组织五项身心健康指标》调查其职业紧张、抑郁症状、失眠症状、疲劳蓄积和生活满意度情况。结果 研究对象周工作时间中位数和第25、75百分位数为63(49,77) h；其中，周工作时间>40 h的长工者占92.2%(1 978/2 145)，周工作时间≥55 h的超长工时外卖员占70.1%(1 504/2 145)。研究对象职业紧张、抑郁症状、失眠症状、疲劳蓄积、低生活满意度检出率依次为30.1%、27.5%、34.7%、40.8%和75.1%。研究对象周工作时间越长者，职业紧张和疲劳蓄积的检出率均越高（P值均<0.01）。多因素logistic回归分析结果显示，在排除混杂因素的影响后，周工作时间≥55 h的超长工时是导致研究对象检出职业紧张和疲劳蓄积的影响因素（P值均<0.05）。结论 送餐平台外卖员普遍存在长工时工作的情况；超长工时工作是引起其职业紧张和疲劳蓄积的危险因素。更多还原

【Abstract】 Objective To investigate the current status of long working hours of food-delivery workers from food-delivery platform, and analyze its impact on their health such as occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction. Methods A total of 2 145 food-delivery workers from two food-delivery platforms in Guangzhou City were selected as the research subjects using convenience sampling method. The occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction were investigated using the Core Occupational Stress Scale, Patient Health Questionnaire-9 items, Self-sleep Management Questionnaire, Self-diagnosis Questionnaire of Fatigue Accumulation of Workers, and World Health Organization Five-item Well Being Index. Results The median and the 25th and 75th percentiles of weekly working hours were 63(49,77) hours. And 92.2%(1 978/2 145) of workers, who worked more than 40 hours per week, were long working hours workers. While 70.1%(1 504/2 145) workers, who worked 55 hours or more per week, were ultra-long working hours workers. The detection rate of occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and low life satisfaction was 30.1%, 27.5%, 34.7%, 40.8%, and 75.1%, respectively. The longer the weekly working hours of the research subjects, the higher the detection rate of occupational stress and fatigue accumulation(all P<0.01). The results of multivariate logistic regression analysis showed that ultra-long working hours(weekly working hours ≥55 hours) was the influencing factor of occupational stress and fatigue accumulation after excluding the influence of confounding factors among workers(all P<0.05). Conclusion The food-delivery workers of food-delivery platforms generally work long hours. Ultra-long working hours is a risk factor for occupational stress and fatigue accumulation among these workers.更多还原
