This study analyzes the longitudinal association between precarious employment and physical and mental health in a dualized labor market by disaggregating between-employee and within-employee effects and considering mobility in precariousness of employment. Analyses were based on the German Socio-Economic Panel from 2002 to 2018 considering all employees ages 18 to 67 years (n = 38,551). Precariousness of employment was measured as an additive index considering working poverty, nonstandard working time arrangements, perceived job insecurity, and low social rights. Health outcomes were mental and physical health. Random effects models were used and controlled for sociodemographic and socioeconomic variables. Results indicated that the association between precariousness of employment and mental and physical health is mainly based on between-employee differences and that prolonged precariousness of employment or upward or downward mobility are associated with poor health. We found evidence of polarization in health by precariousness of employment within a dualized labor market.

本研究通过分解员工之间和员工内部的影响并考虑就业不稳定中的流动性，分析了二元劳动力市场中不稳定就业与身心健康之间的纵向关联。分析基于 2002 年至 2018 年的德国社会经济小组，考虑到所有 18 至 67 岁的员工（n = 38,551）。就业的不稳定性被衡量为一个附加指数，考虑了工作贫困、非标准工作时间安排、感知的工作不安全感和低社会权利。健康结果是心理和身体健康。随机效应模型被用于和控制社会人口和社会经济变量。结果表明，就业不稳定性与身心健康之间的关联主要基于员工之间的差异，长期的就业不稳定性或向上或向下流动与健康状况不佳有关。我们通过二元劳动力市场中的就业不稳定发现了健康两极分化的证据。
