Bethany Barone Gibbs
Associate Adjunct Professor

Associate Professor
Department of Health and Human Development and Clinical and Translational Science

Dr. Bethany Barone Gibbs is trained in cardiovascular and physical activity epidemiology and studies the prevention and treatment of cardiometabolic disease through healthy lifestyle behaviors. Her interests include population and intervention studies of physical activity, sedentary behavior, and eating habits as they relate to hypertension, subclinical cardiovascular disease, diabetes, and obesity.

Her research has recently focused on sedentary behavior, a behavior distinct from moderate-to-vigorous intensity physical activity. These studies have evaluated measurement and methods, longitudinal associations in cohort studies, and interventions to decrease sedentary behavior in 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 health coaching, sit-stand desks, and activity prompters can decrease blood pressure and arterial stiffness (NHLBI).

She also leads the Pittsburgh site for the Pregnancy 24/7 Study, a longitudinal cohort in 500 pregnant women that will investigate the 24-hour activity cycle (sedentary behavior, physical activity, and sleep) across pregnancy and its relationship with pregnancy outcomes (NHLBI). She is a consultant on the CARDIA Ancillary Study evaluating physical activity and sedentary behavior and is Vice Chair of the American Heart Association Lifestyle Council Physical Activity Committee.

Bethany is a Pittsburgh native, growing up in the South Hills, and enjoys theater and getting outdoors with her husband and two children.

Scholarly Interests

Dr. Barone Gibbs has scholarly interests in physical activity and sedentary behavior epidemiology, sedentary behavior research methods, the physiological effects of prolonged sitting and exercise, subclinical cardiovascular disease, and behavioral lifestyle interventions to prevent cardiometabolic diseases. Populations of interest include women during and following pregnancy, occupational cohorts such as desk workers, and adults with cardiovascular risk factors.
