Research Making a Difference
WHY IT'S IMPORTANT
Over the past 30 years, rates of obesity have increased and remain high for adults and children. More than one-third of U.S. adults and about 17 percent of children are now obese.

Obesity, Nutrition, and Physical Activity
Overweight and obesity are highly prevalent in some racial and ethnic minority groups. Rates of obesity in American adults are highest in blacks, followed by Hispanics, then whites.
A person’s sex may also affect the way the body stores fat. Obesity is more prevalent in women than in men, and obesity is known to increase the risk of cardiovascular diseases. Read more about Women’s Health.
KEY ACCOMPLISHMENTS
- NHLBI studies address the increasing prevalence of obesity and translate findings into strategies to prevent or treat obesity and its health consequences.
- We continue our longstanding commitment to educate the public, especially high-risk populations, about ways to prevent and treat obesity.
- NHLBI research was featured in the Emmy-nominated HBO Documentary Films series on obesity, The Weight of the Nation.
- The NHLBI Director co-chairs the NIH Obesity Research Task Force, which was organized to accelerate obesity research across all of NIH.
OPPORTUNITIES & CHALLENGES
In 2016, NHLBI released its Strategic Vision, which will guide the Institute’s research activities for the coming decade. Many of the objectives and compelling questions identified in the plan focus on obesity, nutrition, and physical activity. For example, researchers will look at ways to assess dietary intake and identify eating patterns and types of foods that contribute to maintaining a healthy weight. That examination may lead to new strategies that help lower risks of cardiovascular diseases, such as heart disease and high blood pressure.

Advancing the Research
Learn about some of the NHLBI’s efforts to support and advance research on obesity, nutrition, and physical activity.
We Perform Research
NHLBI’s Division of Intramural Research, including its Laboratory of Obesity and Aging Research, is actively engaged in discovering new insights about obesity, nutrition, and physical activity that can lead to improved health care, practices, and policies to prevent or treat obesity and its health consequences. The Laboratory of Obesity and Metabolic Diseases Lab seeks to understand how obesity induces metabolic disorders.
We Fund Research
The NHLBI Division of Cardiovascular Sciences supports research on how overweight and obesity relate to heart disease and research on interventions to reduce or maintain body weight and reduce cardiovascular disease risk factors. The Center for Translation Research and Implementation Science supports the translation and implementation of research, including obesity research, into clinical practice. The Division of Lung Diseases and its National Center for Sleep Disorders Research supports research on sleep and sleep disorders, including the interplay between obesity and lifestyle and sleep disorders such as sleep apnea.
The Promise of Precision Medicine
Through NHLBI’s Trans-Omics for Precision Medicine (TOPMed) program, researchers will use data from studies focused on heart, lung, blood and sleep disorders to better predict, prevent, diagnose, and treat obesity based on a patient’s unique genes, environment, and molecular signatures. Learn more about NHLBI precision medicine activities.
Leading Women’s Health Research
The NHLBI’s Women’s Health Initiative Strong and Healthy Study (WHISH) is a large clinical trial investigating the health benefits of a physical activity program in older women who participate in the Women’s Health Initiative (WHI) extension study. The recently completed Objective Physical Activity and Cardiovascular Health Study (OPACH) used wearable devices to discover characteristics of physical activity important for maintenance of cardiovascular health in older women.
Providing Family-Based Weight Loss Treatment
The Primary Care Pediatrics Learning Activity and Nutrition With Families (PLAN) studies the effect of a behavioral weight control intervention in centralized primary care settings for children, their parents, and siblings who are overweight or obese. This trial will provide important information regarding the effectiveness of using a family-based treatment for childhood obesity in primary care settings.
Coordinating Efforts to Address Childhood Obesity
The Childhood Obesity Prevention & Treatment Research (COPTR) Consortium tests interventions that slow weight gain in children. Interventions target home, school, community youth organizations, and primary care settings for children who live in low income and ethnically diverse neighborhoods. The goal is to prevent obesity-related cardiovascular disease risk factors in children.
Refining Ways to Reduce Behaviors that Contribute to Obesity
The NHLBI and other NIH Institutes led the Obesity Related Behavioral Intervention Trials (ORBIT) to translate findings from basic research on human behavior into interventions that can change obesity-related health behaviors. These studies included families and a variety of demographic groups. A key finding from one study focuses on the importance of targeting psychological factors in obesity treatment.
Understanding the Relationship Between Community Programs and Policies and Children’s Health
The Healthy Communities Study (HCS) explored how characteristics of programs and policies are related to children’s weight, diet, and activity levels in diverse communities across the country. Findings from this study suggest that the amount, kind, and duration of community programs and policies makes a meaningful difference in childhood obesity.
Collecting Data on Obesity, Nutrition, and Physical Activity
NHLBI-funded population studies are also collecting data on obesity, nutrition, and physical activity. For example, the Framingham Heart Study identified common factors that contribute to cardiovascular disease across generations. The Jackson Heart Study investigated the causes of cardiovascular disease in African-Americans to learn how best to prevent these diseases. The Strong Heart Study examined cardiovascular disease and its risk factors among American Indian men and women.
Developing Personalized Strategies for Obesity Treatment
The Accumulating Data to Optimally Predict obesity Treatment (ADOPT) Core Measures Project identified a set of 50 Core Measures, or factors, spanning four domains—behavorial, biological, environmental, and psychosocial—that may influence how people respond to obesity treatments. The ADOPT Project encourages researches to use these Core Measures consistently in new clinical trials to develop targeted and potentially more effective strategies to treat obesity.
Programs and Resources for Obesity Prevention and Treatment
The NHLBI has supported evidence-based health education programs to promote healthy lifestyle changes, such as heart-healthy eating and physical activity, to prevent obesity and obesity-related cardiovascular complications.

Use our We Can!® (Ways to Enhance Children’s Activity and Nutrition) resources to help children maintain a healthy weight.
