Dr. Bethany Barone Gibbs is an Associate Professor of Health and Human Development, and Clinical and Translational Science at the University of Pittsburgh. She trained in cardiovascular epidemiology and studies the prevention and treatment of obesity and cardiometabolic disease through healthy lifestyle behaviors. Her interests include population and intervention studies of physical activity, sedentary behavior, and eating habits as they related to hypertension, subclinical cardiovascular disease, diabetes, and obesity.
Most recently, her research has focused on sedentary behavior, a behavior distinct from moderate-to-vigorous intensity physical activity. These sedentary behavior studies have evaluated measurement and methods, longitudinal associations in cohort studies, and intervention methods to decrease sedentary behavior in special populations including office workers, pregnant women, chronic low back pain, and older adults. She is currently the Principal Investigator of a 3-month randomized clinical trial evaluating whether a sedentary behavior intervention using sit-stand desks and activity prompters can decrease blood pressure and arterial stiffness, funded by the National Heart Lung and Blood Institutes. She also recently completed a cohort study funded by the American Heart Association that objectively measured sedentary behavior and cardiovascular health across all three trimesters of pregnancy. Bethany is a Pittsburgh native, growing up in the South Hills, and enjoys theater and getting outdoors with her husband and two children in her free time.

Our lab is always looking for motivated student volunteers and qualified MS or PhD candidates interested in our current projects studying: sedentary behavior, physical activity, cardiovsacular health, pregnancy, and lifestyle interventions - please inquire at firstname.lastname@example.org.
Sedentary behavior, physical activity, sleep, and cardiovascular risk in pregnancy: the Pregnancy 24/7 cohort study (NHLBI R01 HL153095).
Effect of Reducing Sedentary Behavior on Sleep: an Ancillary Study to RESET BP (NHLBI R01 HL147610). 4/1/2019 - 2/28/2023 Role: Co-Investigator (PI Kline).
RESET BP: Effect of Reducing Sedentary Behavior on Blood Pressure (NHLBI R01 HL134809). Aug 2017-Jun 2022. The purpose of this randomized clinical trial is to test whether an intervention aimed at reducing sedentary behavior can decease blood pressure in working adults with pre-to-Stage hypertension.
Sedentary Behavior in Pregnancy and Cardiovascular Health: the Monitoring Movement and Health (MoM Health) Study PI: Barone Gibbs Jan 2017 through Dec 2019 This study will measure 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.
