    Choi et al. conducted a prospective study of 5-year follow-up to examine the association of employment status and income with self-rated health among waged workers with disabilities (1). Adjusted odds ratios (ORs) (95% confidence intervals [CIs]) of workers with a precarious employment status and lowest income for poor self-rated health were 1.22 (1.21-1.23) and 1.81 (1.80-1.83), respectively. I have some concerns about their study.

    First, Ferrante et al. examined the association between precarious employment and mental health with special reference to financial strain (2). Mental health status was assessed by the Patient Health Questionnaire 2-item scale score or the Mental health Component Summary 12-item scale score. Adjusted prevalence ratios (95% CI) of precarious workers for depression was 1.92 (1.09-2.93). In contrast, risk of poor mental health in precarious workers was not significant. Furthermore, financial strain was a strong mediator on the relationship, and a significant relationship was only observed in male workers. Sex difference and socioeconomic status might be important contributors on the relationship, which should be specified by a prospective study.

    Regarding the first query, Jang et al. conducted a follow-up study to know the effect of precarious employment on the development of new-onset severe depressive symptoms (3). Severe depressive symptoms were measured using the 11-item Center for Epidemiologic Studies Depression Scale. ORs (95%...
