The research published in the Journal Neurology conducted by Kaiser Permanente stated that Multiple sclerosis (MS) is more common in black women than in white women, according a new study. This study brought a great contradiction as till now it was believed that Black ones are less vulnerable to this disease. The e-health records of over 3.5 million members of Southern California were estimated from the 2008-2011. 496 new MS patients were recorded. Among the reported new cases, black patients contributed to 47% greater likelihood of MS compared to white patients. Results conveyed that Portuguese had a 50% reduced risk compared to white patients and Asians had 80% lower chance than whites.
Researchers suggest that the possible explanation of the findings to be the people with darker skin tones have lower vitamin D levels and therefore an increased risk of MS.
