The contribution of morbidity and unemployment for the reduced labor market participation of individuals with neurofibromatosis 1 in Finland.

Neurofibromatosis 1 (NF1) is a multisystem disorder associated with, for example, a high risk for cancer, a variety of behavioral and cognitive deficits, low educational attainment and decreased income. We now examined the labor market participation of individuals with NF1. We analyzed the numbers of days of work, unemployment, and sickness allowance among 742 Finnish individuals with NF1 aged 20-59 years using nationwide register data from Statistics Finland and the Social Insurance Institution of Finland. The individuals with NF1 were compared with a control cohort of 8716 individuals matched with age, sex, and the area of residence. Individuals with NF1 had a significantly lower number of working days per year than the controls (rate ratio [RR] 0.93, 95% CI 0.91-0.95). Unemployment (RR 1.79, 95% CI 1.58-2.02), and sickness absence (RR 1.44, 95% CI 1.25-1.67) were more frequent in the NF1 than in the control group. The causes of sickness allowances were highly concordant with the previously reported morbidity profile of NF1 including neoplasms, cardiovascular disease, mental and behavioral diseases, and neurological diseases. In conclusion, NF1 significantly interferes with labor market participation via both unemployment and morbidity. Unemployment seems to cause more days of not working than sickness absence.

The rare disease neurofibromatosis 1 as a source of hereditary economic inequality: Evidence from Finland.

PURPOSE: This study investigated whether individuals with neurofibromatosis 1 (NF1) fare worse than individuals without NF1 in terms of economic well-being. NF1 is relatively common in the population and provides an informative case of a rare hereditary disease. METHODS: We examined a subset of 692 individuals with verified NF1 from the Finnish total population-based NF1 cohort and compared that with 7407 control individuals matched for age, sex, and municipality during 1997-2014. Economic well-being was operationalized with annual work earnings and total income, including social income transfers. RESULTS: NF1 significantly worsened economic well-being. Low education, increased morbidity, and reduced labor market participation partly explained the effect of NF1. Yet, NF1 was independently associated with lower income even after adjusting for these factors. Furthermore, NF1 had a larger negative effect on income from work than it had on total income, which indicated that the Finnish social security system partly compensated the labor market losses suffered by individuals with NF1. NF1 had a larger impact on economic inequality for men than for women. CONCLUSION: NF1 contributes to economic inequality. A hereditary disease may convey worse economic well-being over several generations.

A rare disease and education: Neurofibromatosis type 1 decreases educational attainment.

Rare heritable syndromes may affect educational attainment. Here, we study education in neurofibromatosis 1 (NF1) that is associated with multifaceted medical, social and cognitive consequences. Educational attainment in the Finnish population-based cohort of 1408 individuals with verified NF1 was compared with matched controls using Cox proportional hazards model with delayed entry and competing risk for death. Moreover, models accounting for the effects of cancer at age 15-30 years, parental NF1 and developmental disorders were constructed. Overall, the attainment of secondary education was reduced in individuals with NF1 compared to controls (hazard ratio 0.83, 95%CI 0.74-0.92). History of cancer and developmental disorders were major predictors of lack of secondary education. Individuals with NF1 obtained vocational secondary education more often than general upper secondary education. Consequently, NF1 decreased the attainment of Bachelor's and Master's degrees by 46%-49% and 64%-74%, respectively. Surprisingly, the non-NF1 siblings of individuals with NF1 also had lower educational attainment than controls, irrespective of parental NF1. In conclusion, NF1 is associated with reduced educational attainment and tendency for affected individuals to obtain vocational instead of academic education. Individuals living with NF1, especially those with cancer, developmental disorders or familial NF1, need effective student counseling and learning assistance.
