Barone Gibbs Receives $3.4 Million NIH Grant

Published on 9/22/2017 9:35:00 AM

Bethany Barone Gibbs, an Assistant Professor in the Department of Health and Physical Activity, and Clinical and Translational Science at the University of Pittsburgh, has received a $3.4 million grant from the National Heart, Lung, and Blood Institutes (NHLBI) of the National Institutes of Health (NIH). Over the next five years, Barone Gibbs will be the principal investigator for: The Effect of Reducing Sedentary Behavior on Blood Pressure.

The primary aim of the study is to evaluate whether reducing sedentary behavior in desk workers with elevated blood pressure can help reduce blood pressure. The trial will evaluate whether a three-month sedentary behavior intervention can decrease blood pressure and improve other vascular health measures in desk-based, working adults with prehypertension and hypertension. Intervention techniques will include individual in-person and phone contacts, sit-stand desk attachment, wrist-worn activity prompter, and text messages.

By comparing to a no treatment, control group, these results could provide a new therapeutic strategy for blood pressure control in adults with prehypertension and hypertension if it is demonstrated that reducing sedentary behavior is efficacious for lowering blood pressure.

Gibbs also is currently the primary investigator on a Sedentary Behavior in Pregnancy and Cardiovascular Health: The Monitoring Movement and Health (MoM Health). This study, sponsored by the American Heart Association, is measuring the effect of sedentary behavior and physical activity across each trimester in a cohort of pregnant women. The aims of the MoM Health Study are to describe patterns of sedentary behavior across pregnancy, study whether sedentary behavior is associated with gestational weight gain, blood pressure, and other pregnancy outcomes, and evaluate determinants of sedentary behavior in this population.

Since joining the Health and Physical Activity faculty in 2010, Barone Gibbs has focused her research on population and intervention studies of physical activity, sedentary behavior, and eating habits as they related to hypertension, subclinical cardiovascular disease, diabetes, and obesity. She is trained in cardiovascular epidemiology and studies the prevention and treatment of obesity and cardiometabolic disease through healthy lifestyle behaviors.
