Jason P. Block, M.D.

RWJF Health & Society Scholar:

General Internal Medicine, Epidemiology

Area(s) of Expertise:
Overweight and Obesity, Nutrition, Stress, Neighborhoods



I am a general internal medicine physician with training in epidemiology and population health.  Working with interdisciplinary teams, my research follows two tracks – examining the geographic influences on the obesity epidemic and intervening in multiple settings to promote weight loss and overall wellness, especially at the environmental level.  I have completed studies on the geographic distribution of food establishments and whether proximity to food establishments is associated with body weight in several cohorts, especially the Framingham Heart Study Offspring Cohort.  On the intervention front, I am exploring point-of-purchase interventions or policies to improve dietary choices in workplaces and food establishments.  I have conducted several studies in workplace cafeterias, exploring whether price adjustments, educational messaging, or alterations in the presentation of products changes purchasing patterns of healthy and unhealthy foods.  I also am evaluating the coming federal regulation that will require calories to be posted on menus in chain restaurants and exploring financial incentives for weight loss and overall wellness, both through health insurance-based incentives and direct financial incentives, at several workplaces.  My work has been featured by NPR, the New York Times, the Wall Street Journal, and USA Today, among other media outlets.
