A higher neighborhood advantage, or socioeconomic status, of where a person lives contributes to a lower risk of having a stroke no matter the person’s race, according to findings published in the Oct. 14 online issue of Neurology®, the medical journal of the American Academy of Neurology.
The report from the University of Alabama at Birmingham REasons for Geographic And Racial Differences in Stroke study shows this effect is the same for black and white adults, both men and women.
“More blacks than whites in the United States have strokes and die from strokes,” said Virginia Howard, Ph.D., lead author of the study and professor in the UAB School of Public Health Department of Epidemiology. “More people who live in the Southeastern area known as the stroke belt have stroke and die from stroke compared to those who live in the rest of the United States.”
This study showed that residents in more disadvantaged neighborhoods had greater stroke risk than those who lived in more advantaged neighborhoods. The neighborhood index is composed of six factors, including a higher value of housing units and higher proportion of residents employed in professional occupations. A higher score in all of these categories leads to a higher advantaged neighborhood.
The observation was true even after adjustment for age, race, sex and region of the country. But after adjustment for other stroke risk factors, there was no association between the level of the neighborhood advantage and stroke risk, suggesting that those living in more disadvantaged neighborhoods are more likely to develop risk factors including hypertension, diabetes and smoking. Because of being more likely to develop these risk factors, they are at higher risk of stroke.
