Labor market consequences of childhood onset type 1 diabetes

- Childhood type 1 diabetes (T1DM) is associated with worse labor market outcomes.
- We use 20 years' register data on employment and earnings for 2485 people with T1DM.
- The negative effect on earnings is partly channeled through occupational field.
- Early child health may impact socioeconomic achievement in adulthood.

This paper examines the effect of the onset of Type 1 Diabetes Mellitus (T1DM) before 15 years of age on labor market outcomes and contributes to the literature on effects of childhood health on adult socioeconomic status. Using national Swedish socioeconomic register data 1991-2010 for 2485 individuals born 1972-1978 with onset of T1DM in 1977-1993, we find that T1DM in childhood has a negative effect on labor market outcomes later in life. Part of the T1DM effect is channeled through occupational field which may be related to both choice and opportunities. Although the magnitude of the effect is only directly generalizable to illnesses with similar attributes as T1DM, the results suggest that causality in the often observed correlation between health and socioeconomic status, at least partly, is explained by an effect running from health to earnings. This has implications for research and policy on strategies to reduce socioeconomic-related health inequality. Our findings also shed light on productivity losses, measured by employment status and earnings due to childhood onset T1DM, which have implications for both the individual and society.
