Socioeconomic factors, particularly healthcare expenditures per person, were significantly associated with MS prevalence in a study of more than 203 countries. The association was as significant as links to latitude (distance from the equator), long known to be a factor in MS risk. The study, partly funded by the National MS Society, speaks to the importance of ensuring that all people with MS have access to high quality and affordable care so that a timely and accurate diagnosis can be achieved. People who live at higher latitudes – further from the equator – are more likely to have MS. This might be because vitamin D levels (from sunlight exposure) are lower at higher latitudes. Distance from the equator is also associated with increasing national wealth, so this team explored whether socioeconomic factors might also play a role in latitudinal differences in MS risk. The research team from Johns Hopkins University and the University Teaching Hospital, Lusaka, Zambia, analyzed data from databases and scientific studies in 203 countries and territories. For each location, researchers examined factors related to the economy and health care expenditures. They also reviewed lifestyle factors such as obesity and tobacco use. The results show significant associations between the national prevalence of MS (the number of people living with a diagnosis of MS within a given period of time) and all economic and health systems factors. The primary factors associated with increased rates of MS were greater health expenditure per person and higher latitude. Other factors included number of neurologists per person and number of MRI units per person. Associations with lifestyle factors were not significant. The results show that socioeconomic factors may be affecting MS prevalence rates by affecting MS diagnosis and reporting. Further research is needed to confirm these findings and explore what strategies can improve the diagnosis of MS in areas with reduced resources. Learn more… Getting specific information on the prevalence and demographics of people living with MS is crucial to studies such as these, and will help deepen our understanding of healthcare access and other issues. The Society recently updated the prevalence of MS in the United States and helped the Multiple Sclerosis International Federation update the global prevalence.

About Multiple Sclerosis Multiple sclerosis is an unpredictable disease of the central nervous system. Currently there is no cure. Symptoms vary from person to person and may include disabling fatigue, mobility challenges, cognitive changes, and vision issues. An estimated 1 million people live with MS in the United States. Early diagnosis and treatment are critical to minimize disability. Significant progress is being made to achieve a world free of MS. About the National Multiple Sclerosis Society The National MS Society, founded in 1946, is the global leader of a growing movement dedicated to creating a world free of MS. The Society funds cutting-edge research for a cure, drives change through advocacy and provides programs and services to help people affected by MS live their best lives.
