Healthy Communities and Behavior Change


Jennifer Sacheck

Jennifer Sacheck's research interests lie at the intersection of nutrition, physical activity, and health promotion. She was initially drawn to this field through her early studies in muscle physiology and more recently through obesity and chronic disease prevention research which has spanned basic science to community-based work.

CHOMPS - Coupons for Healthier Options for Minors Purchasing Snacks

The acronym CHOMPS stands for “Coupons for Healthier Options for Minors Purchasing Snacks.” The work is being conducted by researchers at Tufts University and Michigan State University, in cooperation with Shape Up Somerville and other community partners and researchers. This project is supported by Agriculture and Food Research Initiative. Competitive Grant no. 2014-69001-21756 from the USDA National Institute of Food and Agriculture.

Strong Women

StrongWomen envisions a diverse community of women who are fit, strong, and healthy; in turn these empowered women become agents of change for their families, communities, and beyond.

John Hancock Research Center on Physical Activity, Nutrition, and Obesity Prevention

In 1999, Dr. Miriam Nelson founded the Center for Physical Fitness within the Friedman School of Nutrition Science and Policy, under the guidance and support of Dean Irwin Rosenberg. The Center, while initially small, had big goals – to improve the physical activity patterns and fitness of Americans.

Shape Up Somerville

Funded by the Centers for Disease Control and Prevention, Shape Up Somerville: Eat Smart. Play Hard. was a 3-year (2002-2005), environmental change intervention designed to prevent obesity in culturally diverse, high-risk, early-elementary school children. Led by Dr. Christina Economos (N96), the Shape Up team developed and implemented strategies designed to create energy balance for 1st-3rd graders in Somerville. In before-, during-, and after-school environments, interventions were focused on increasing the number of physical activity options available to children throughout the day and on improving dietary choices.

The Daily D Study: Impact of Vitamin D Supplementation on Cardiometabolic Risk in Schoolchildren

Vitamin D deficiency has been linked to the development of cardiovascular disease and it is estimated that six million children are currently vitamin D deficient. Vitamin D deficiency is even more common in northern latitudes, amongst some minority groups with darker skin pigmentation, and in those who are overweight or obese. In these groups, higher supplemental doses may be needed to maintain optimal serum levels and to prevent cardiovascular risk.

Daniel Hatfield

Dan Hatfield is an Instructor in the Developing Healthy Communities Online Graduate Certificate program at the Friedman School and Senior Specialist, Engagement and Analytics, at ChildObesity180, an organization that develops, implements, evaluates, and scales high-impact obesity prevention initiatives nationwide. Dr. Hatfield completed a BA in English at Princeton University and an MS in Nutrition Communication and a PhD in Food Policy & Applied Nutrition, both at Tufts.

If You Build It, They Will Come

As the sedan cruises around a Massachusetts town, Mark Fenton juts his arm out of the passenger window like a zealous tourist, snapping seemingly random photos of crosswalks, traffic signs, rollerbladers, trash cans, jay walkers. The car comes to a stop, and Fenton sprints off, jogging down a bike trail to see what it connects to, what businesses are nearby, what drinking fountains and mile markers he can see.

Stay Active for a Healthy Heart

People in their 70s can likely lower their risk of stroke and heart attack with regular moderate exercise such as walking, according to a Tufts study, which provides some of the first evidence that continuing to exercise as we age really does make a difference.

The cause of nearly a third of all deaths, cardiovascular disease is the number-one killer worldwide, according to the World Health Organization. In the United States, more than a third of all adults have some form of the disease, including about half of people over age 60.

New Dietary Guidelines

In the wake of the release of the new Dietary Guidelines for Americans, Circulation, a journal of the American Heart Association, has published an Authoritative Review on the dietary and policy priorities by Friedman's Dean, Dariush Mozaffarian.
