Dr. Jason Block

Associate Professor
Harvard Medical School

Dr. Block is a general internal medicine physician with training in epidemiology and population health.  Working with interdisciplinary teams, his research follows two tracks (1) examining the geographic influences on the obesity epidemic and (2) intervening in multiple settings to promote weight loss and overall wellness, especially at the environmental level.  Dr. Block has completed studies on the geographic distribution of food establishments. He has explored whether proximity to food establishments is associated with body weight in several cohorts, including the Framingham Heart Study Offspring Cohort. On the intervention front, Dr. Block explores point-of-purchase interventions or policies to improve dietary choices in workplaces and food establishments. He has conducted several studies in workplace cafeterias, exploring whether price adjustments, educational messaging, or alterations in product presentation changes purchasing patterns of healthy and unhealthy foods. His current studies include (1) evaluating the coming federal regulation that will require calories to be posted on menus in chain restaurants and (2) exploring financial incentives for weight loss and wellness, through health insurance-based incentives and direct financial incentives, at several workplaces.
