(Chicago, IL) — A new study led by a researcher from Northwestern University is finding a link between segregated neighborhoods and high blood pressure. The study looked at data from nearly 23-hundred African Americans in four major cities whose health has been tracked for decades. It found that those who moved out of highly segregated neighborhoods saw a drop in their blood pressure. The study concludes that the drop is most likely related to a reduction in stress, better access to exercise, better medical care and healthier food. The study was published in JAMA Internal Medicine.
