Job Insecurity and Substance Use in the United States: Stress, Strain, and the Gendering of Precarious Employment

Research on the social determinants of health demonstrates that workers who feel insecure in their jobs suffer poorer health as a result. However, relatively few studies have examined the relationship between job insecurity and illegal substance use, which is closely related to health. In this study, we develop a theoretical model focusing on two intervening mechanisms: health and life satisfaction. Additionally, we examine differences in this relationship between women and men. We test this model using logistic regression models of substance use for women and men based on longitudinal data from the National Survey of Midlife Development in the United States. The results indicate that job insecurity is associated with a significantly higher probability of illegal substance use among women but not men. We interpret this as further evidence of the gendering of precarious employment. This relationship is not channeled through health or life satisfaction, but there is evidence that job insecurity has a stronger association with illegal substance use for women with poorer overall health.
