title: In-Work Poverty and Self-Rated Health in a Cohort of Working Germans: A Hybrid Approach for Decomposing Within-Person and Between-Persons Estimates of In-Work Poverty Status.
abstract: In this study, we investigated whether self-rated health (SRH) can be predicted by in-work poverty and how between-persons and within-person differences in the poverty status of people who are working contribute to this relationship. We used a logistic random-effects model designed to test within-person and between-persons differences with data from a nationally representative German sample with 19 waves of data collection (1995-2013) to estimate effects of between-persons and within-person differences in working poverty status on poor SRH. Interactions by age and sex were tested, and models controlled for sociodemographic, socioeconomic, and work-related characteristics. We found significant differences in SRH between individuals with different working poverty status but no evidence that within-person differences in working poverty status are associated with poor SRH. The association between in-work poverty and SRH was significantly stronger for women but did not differ significantly by age. All findings were robust when including sociodemographic, socioeconomic, and working characteristics. In this sample of German adults, we found a polarization of poor SRH between the working nonpoor and the working poor but no causal association of within-person differences in working poverty status with SRH.
