项目摘要

Background "Karo-shi", the death caused by overworking and chronic fatigue, is considered to be related to sleeping condition. And a developing of the method of evaluating chronic fatigue by overworking may be very important to prevent "karo-shi" caused by cardiovascular disease.Aim To clarify the relationships between working hours or sleeping type and mental status and chronic fatigue as risk factors of cardiovascular disease.Methods On 1505 male day workers, effects of sleeping type according to Morning-Evening Scale and working hours/month subdivided into 6 group were determined using Self rating Depression Scale(SDS) and Cumulative Fatigue Symptom Index(CFSI) as dependent variables, and other potential covariates as independent variables by ANCOVA.Results In the group Morning type, BMI, mean blood pressure, HbA1c, total serum cholesterol and HDL cholesterol were significantly increased. The results of ANCOVA indicate that in the group working 【greater than or equal】260 hours/month and that scores of SDS and CFSI in evening type were significantly higher than other groups.Conclusions The present results clarified that 260 or more hours/month working hours increased fatigue symptoms, and suggests that sleeping type affects on the mental status, chronic fatigue and other cardiovascular risk factors.

研究背景过劳死是由于过度劳累和慢性疲劳引起的死亡，一般认为与睡眠状况有关。目的探讨工作时间、睡眠方式与慢性疲劳作为心血管疾病危险因素的关系。以抑郁自评量表（SDS）和疲劳症状累积指数（CFSI）为因变量，结果晨型组BMI、平均血压、HbA 1c、血清总胆固醇、HDL胆固醇均显著升高，晨型组BMI、平均血压、HbA 1c、血清总胆固醇、HDL胆固醇均显著升高，晨型组BMI、平均血压、HbA 1c、血清总胆固醇、HDL胆固醇均显著升高。协方差分析结果显示，工作时间≥ 260 h/月组的SDS和CFSI得分均显著高于其他组，夜间睡眠类型的SDS和CFSI得分显著高于其他组。结论工作时间≥ 260 h/月组疲劳症状明显增加，睡眠类型影响精神状态、慢性疲劳等心血管危险因素。
