Work overload and risk behaviors in motorcyclists

ABSTRACT Objective: to analyze the association between work overload and risk behaviors adopted by motorcyclists. Method: a cross-sectional study of injured motorcycle drivers hospitalized at the Hospital da Restauração Governador Paulo Guerra in the city of Recife, PE, from May to September 2016. A questionnaire was applied containing sociodemographic variables related to work overload and risk behaviors adoption. Odds Ratio (OR) and 95% Confidence Interval were used to analyze the association between the variables. Results: there was a predominance of males (97.6%), mean age 31.44 years (SD = 9.50). There was an association of sleep/fatigue at the accident time with difficulties carrying out work tasks (OR = 3.7), feeling tired during work (OR = 4.6) and feeling under pressure to carry out work tasks (OR = 3.5). Conclusion: work overload was associated with risk behaviors adoption. It is believed that this fact can have an impact on the occurrence and severity of accidents.摘要 研究目的：分析摩托车骑手的工作负荷与所采取的风险行为之间的关联。 研究方法：本研究为横断面研究，研究对象为2016年5月至9月期间，于巴西累西腓市雷斯特拉唐总督保罗·格拉医院（Hospital da Restauração Governador Paulo Guerra）住院治疗的受伤摩托车驾驶员。研究采用调查问卷收集与社会人口学特征、工作负荷及风险行为采取情况相关的变量数据，通过比值比（Odds Ratio，OR）及95%置信区间对变量间的关联进行分析。 研究结果：研究对象以男性为主（占比97.6%），平均年龄为31.44岁（标准差SD=9.50）。事故发生时出现睡眠不足/疲劳状况，与完成工作任务存在困难（OR=3.7）、工作期间感到疲惫（OR=4.6）以及承受完成工作任务的压力（OR=3.5）存在显著关联。 研究结论：工作负荷与摩托车骑手的风险行为采取存在关联，该现象或对交通事故的发生及其严重程度产生影响。
