Research on the impact of precarious employment contract on workers' health

最近的研究表明，不稳定的雇佣合同可能会影响工人的健康。我们调查了雇佣合同不稳定的日本工人(兼职、派遣和合同/非正式工人等)的健康状况。使用以前的研究、访谈、健康检查和国家统计数据，对固定工人的数据进行了比较。结果澄清了以下问题：不稳定的工人往往健康状况不佳，较少的病假和与劳动事务有关的伤害(文献综述)；不稳定的工人往往有主观症状，在许多情况下他们不再去医院就诊，或者不能申请工伤赔偿，他们往往没有得到医疗保险的覆盖，或者没有接受体检(访谈)；全职不稳定的工人遭受心理困扰和吸烟习惯的风险更高，以及工人的自评健康在2000年上半年恶化(流行病学研究)。

Recent studies suggest that unstable employment contracts may affect the health of workers. We investigated the health status of Japanese workers with precarious employment contracts(part-time, dispatched, and contract/non-regular workers, etc.) to that of permanent workers using the previous researches, interviews, health examinations and national statistics. As a result, the followings were clarified : Precarious workers often have poor health status, fewer sickness absences and injuries related to labor affairs(literature review); precarious workers tend to have subjective symptoms, there are many cases where they discontinue hospital visits or where they cannot apply for workers' accidents compensation, and they tend to have being uncovered by health insurances or not receiving medical examinations(interviews); full-time precarious workers have higher risk of suffering psychological distress and smoking habits, and that workers' self-rated health deteriorated during the first half of the year 2000(epidemiological studies).
