Health expenditures by countries may explain relationship between multiple sclerosis and latitude – Benin Actu

PARIS, Aug 29 (Benin News) –

Researchers have found that people who live farther from the equator are more likely to develop multiple sclerosis (MS), and have often attributed this to exposure to vitamin D. But countries farther from the equator are also likely to be wealthier than countries closer to the equator.

A new analysis shows that the amount a country spends on health care may help explain the link between multiple sclerosis and latitude, its authors publish in the online edition of Neurology, the U.S. American Academy of Neurology.

According to study author Deanna Saylor, MD, of the Johns Hopkins University School of Medicine in the United States and a fellow of the American Academy of Neurology, the results suggest that MS rates are grossly underestimated in countries with low income and lower healthcare costs could become. This means people have less access to neurologists with the expertise to diagnose MS and MRI scans needed to diagnose.

For this analysis, researchers analyzed data from academic studies and databases to determine current rates of MS in 203 countries and territories. They then grouped these countries into regions of the world and by income level.

MS rates vary by region and income level. For example, in high-income countries, an average of 46 out of 100,000 people had MS, compared to 10 out of 100,000 in low-income countries. Health expenditure per capita was $2,805 (around €2,805) in high-income countries, compared with $45 (€44.8) in low-income countries.

For each location, the researchers looked at gross domestic product per capita, current health expenditure per capita, income level, availability of brain scans to diagnose MS, number of neurologists per capita, and overall health care coverage. They also looked at lifestyle factors such as obesity and smoking.

After adjusting the data for other factors that may affect MS risk, such as age and gender, they found that health spending and latitude were strongly associated with MS rates.

Research has shown that for every one standard deviation increase in per capita health expenditure, the prevalence of MS in a country increases by 0.49. On the other hand, MS prevalence in a country increases by 0.65 for every increase in latitude standard deviation.

They also found that health spending explained some, but not all, of the relationship between latitude and MS. After controlling for other factors, the relationship between latitude and MS decreased by more than 20% when health expenditure per capita is taken into account.

The availability of universal health coverage was associated with higher rates of MS in all regions of the world except Southeast Asia, where universal health coverage was associated with higher rates of MS.

In high-income countries, MS rates depended on most factors, including gross domestic product per capita, current health expenditure per capita, and the number of neurologists, but not smoking and obesity or the number of MRI units per capita. However, no association with any of these factors was observed in low-income countries, which could be explained by the lack of significant differences in the data from those countries, says Saylor.

According to Saylor, the fact that current per capita health care expenditures are very strongly related to national multiple sclerosis rates supports the hypothesis that greater investment in health care leads to more robust reporting of multiple sclerosis rates.

She also points out that the minimal associations between MS rates and lifestyle factors such as smoking and obesity contradict previous hypotheses that lifestyle and drinking patterns largely explain regional differences in reported MS rates.

Saylor warns that strategies are urgently needed to reduce the shortage of trained professionals and critical technologies that prevent accurate assessment of the burden of MS in low-income countries.

She also warns that the current low MS rates being reported in these countries may obscure the need to educate healthcare providers about MS and limit investment in improved diagnosis and treatment in areas where scarce resources are often allocated to diseases are considered to be more common.
