High Blood Pressure Related to Slower Walking Speed

Changes in walking speed can indicate possible health problems and reduce the ability to remain independent, says University of Pittsburgh epidemiologist Caterina Rosano, M.D., senior author of the study, which appears in the March issue of the Journal of the American Geriatrics Society. "For example, when you cross a street, you have to make a lot of decisions that depend on how quickly you can walk. Do I have enough time to get across? Will I slip if I try to hurry? Will I fall? If you have these stressful thoughts every time you come to a corner," says Rosano, "you may decide to visit friends less often, you won't be as comfortable going to the grocery store by yourself and you won't get out as much."

The researchers looked at changes in walking speed of 643 men and women who were, on average, 74 years old when the study began. Participants included 350 people without high blood pressure and 293 who were already taking medication to control blood pressure or whose high blood pressure was diagnosed when they entered the study. Those with high blood pressure were divided into three groups: newly diagnosed, able to control the condition with medication, and unable to control the condition with medication.
