Sleep duration disorders impact the quality of life and energy expenditure in workers. However, there is a lack of understanding about the relationship between sleep duration and energy expenditure at work among motorcycle taxi drivers.
To analyze the relationship between sleep duration and energy expenditure at work in motorcycle taxi drivers.
A cross-sectional study was conducted with 296 male motorcycle taxi drivers from Rio Branco City, western Brazilian Amazon. Methods and Material: The motorcycle taxi driver reported the number of hours daily spent sleeping on a typical day during the week. Uncorrected and corrected energy expenditures of motorcycle taxi drivers during the working day were calculated according to the 2011 Physical Activity Compendium. The metabolic equivalent (MET) was corrected for the basal metabolic rate using the equation proposed by Harris and Benedict.
The relationship between sleep duration and energy expenditure at work was analyzed using fractional polynomial regression.
The mean sleep duration in hours was 7.4 (SD: 1.4). There was a relationship between sleep duration and corrected energy expenditure at work, with a first-degree logarithmic transformation. The nonlinear relationship between sleep duration and uncorrected energy expenditure at work was a fractional polynomial with a power of -0.5 for the first degree.
The results suggest a nonlinear relationship between sleep duration and energy expenditure at work among motorcycle taxi drivers. Motorcycle taxi drivers with short sleep durations had high energy expenditures at work.
睡眠时间紊乱会影响工人的生活质量和能量消耗。然而，对于摩托车出租车司机而言，人们对工作时的睡眠时间与能量消耗之间的关系缺乏了解。
分析摩托车出租车司机工作时的睡眠时间与能量消耗之间的关系。
对来自巴西亚马孙地区西部里奥布兰科市的296名男性摩托车出租车司机进行了一项横断面研究。方法与材料：摩托车出租车司机报告一周内平常一天的每日睡眠时间。根据《2011年体力活动纲要》计算摩托车出租车司机工作日的未校正和校正能量消耗。使用哈里斯和本尼迪克特提出的公式，根据基础代谢率对代谢当量（MET）进行校正。
使用分数多项式回归分析睡眠时间与工作时能量消耗之间的关系。
平均睡眠时间为7.4小时（标准差：1.4）。睡眠时间与工作时的校正能量消耗之间存在关系，呈一阶对数转换。睡眠时间与工作时未校正能量消耗之间的非线性关系是一个一次幂为 -0.5的分数多项式。
结果表明摩托车出租车司机工作时的睡眠时间与能量消耗之间存在非线性关系。睡眠时间短的摩托车出租车司机工作时的能量消耗较高。
