背景 在提出建议以保护人们免受长时间工作造成的潜在有害健康影响时，建立工作时间阈值非常重要。目的 阐明工作时间对疲劳的精神和身体症状的影响，并利用获得的数据确定允许的工作时间。方法使用自评抑郁量表（SDS）和累积疲劳症状指数（CFSI）对男性白班工人进行横断面调查。将工作时间细分为六组，并使用逻辑回归分析计算 SDS 和 CFSI 积极结果的比值比。结果 共有 715 名工人参与。在每月工作 260-279 小时的组中，SDS 以及 CFSI 的“易怒”、“焦虑”和“慢性疲劳”的比值比显着增加。在每月工作时间 >= 280 小时的群体中，CFSI 上“一般疲劳”、“身体疾病”、“焦虑”和“慢性疲劳”的比值比同样显着增加。 结论 目前的结果表明，工作时间应为 260 小时/月，以尽量减少男性日工的疲劳症状。
Background Establishing a threshold number of working hours is very important when making recommendations to protect people from the potentially harmful health effects caused by long working hours.Aim To clarify the influence of working hours on both mental and physical symptoms of fatigue and use the data obtained to determine permissible working hours.Methods Cross-sectional survey of male day-shift workers using the Self-Rating Depression Scale ( SDS) and the Cumulative Fatigue Symptoms Index ( CFSI). Working hours were subdivided into six groups and odds ratios were calculated for positive outcomes on the SDS and CFSI using logistic regression analysis.Results A total of 715 workers participated. In the group working 260-279 h/month, the odds ratios for SDS and 'irritability', 'anxiety' and 'chronic tiredness' of the CFSI were significantly increased. In the group working >= 280 h/month, the odds ratios on CFSI for 'general fatigue', 'physical disorders', 'anxiety' and 'chronic tiredness' were likewise significantly increased.Conclusions The present results clarified that working hours should be,260 h/month in order to minimize fatigue symptoms in male day workers.
