Sources and level of income among individuals with multiple sclerosis compared to the general population: A nationwide population-based study.

INTRODUCTION: Multiple sclerosis (MS) is associated with reduced work capacity, but there is limited knowledge about MS patients' sources of income.
OBJECTIVES: The purpose of this study was to elucidate MS patients' earnings and social benefits compared to those of the general population.
METHODS: From nationwide registers of all residents in Sweden aged 21-64 years in 2010 (n=5,291,764), those with an MS diagnosis (n=13,979) were compared to a propensity score matched reference group (n=69,895). Descriptive statistics and regression models were used to estimate the percentage difference between the MS patients and the matched references regarding the following annual incomes: earnings, disability pension, sickness absence, disability allowance, unemployment compensation and social assistance.
RESULTS: Both MS patients and the matched references received most of their income from earnings followed by disability pension and sickness absence. MS patients that were diagnosed in 2010 had 15% lower earnings than the matched references, while MS patients diagnosed before 2005 had 38% lower earnings. Corresponding figures regarding summed social benefits were 33% and 130% higher for MS patients, respectively.
CONCLUSION: The results indicate that MS patients are overrepresented, in relative and absolute terms, regarding health-related benefits and have lower levels of earnings. However, the redistributing welfare systems appear to financially compensate the MS patients considerably.
