More resources and collaboration needed to support prevention and treatment of obesity

Limited time, financial constraints, neighborhood factors and weight stigma impact efforts to prevent and treat obesity, especially among people in lower-income communities, according to a new American Heart Association scientific statement

2026-01-15

(Press-News.org) Statement Highlights:

More than one-third of adults and children in the U.S. are living with obesity. Obesity rates are highest among non-Hispanic Black children and adults, low-income families, people living in rural areas and adults with a high school education or less. The latest research indicates that barriers to maintaining a healthy weight or participating in weight management programs include: limited access to healthy foods, lack of time to prepare meals and engage in regular physical activity, financial constraints including lack of health insurance and stigma around body weight. Effective obesity prevention and treatment programs include collaboration among government, health care professionals, community organizations and individuals, according to the new scientific statement.

DALLAS, Jan. 15, 2026 — Obstacles to preventing and treating obesity, including limited access to healthy foods, limited time to prepare meals and exercise, neighborhood factors, weight stigma and financial constraints, are more likely to affect people in lower-income communities, according to a new American Heart Association scientific statement published today in the Association’s flagship journal Circulation.

The statement, “Socioeconomic and Structural Barriers to Addressing Obesity in Communities,” highlights multilevel barriers to obesity prevention and management, with an emphasis on social drivers of health, societal culture and biases that may perpetuate harmful attitudes related to body weight and interfere with the success of weight management programs.

Obesity is a chronic health condition characterized by excess body fat that is associated with harm to health. It affects more than one-third of all people in the U.S., both children and adults, across all socioeconomic backgrounds. While genetic factors can contribute to the development of obesity, previous studies have found that genetic predisposition is not the primary driver of high obesity rates. People in lower-income communities are disproportionately impacted by obesity and related health conditions, such as high blood pressure, cardiovascular disease and Type 2 diabetes.

“The latest research indicates that people with fewer resources are more likely to develop obesity because of a combination of factors that influence their everyday, lived experiences, such as socioeconomic stressors that limit access to nutritious foods and regular physical activity or healthy sleep; and cultural factors that make it hard to access obesity care and maintain a healthy weight,” said Fatima Cody Stanford, M.D., M.P.H., M.P.A., M.B.A., FAHA, vice chair of the scientific statement writing group, an associate professor of medicine and pediatrics and an obesity medicine physician scientist at Massachusetts General Hospital and Harvard Medical School, both in Boston.

“We must recognize that obesity is not a personal choice. It is highly influenced by multiple social and environmental factors. This is a critical component for addressing the obesity epidemic in the U.S. and obesity-related health conditions including cardiovascular disease,” Stanford said.

Obesity prevalence and risk factors

Numerous socioeconomic factors are closely linked to obesity. Risk and prevalence of obesity are highest among non-Hispanic Black children and adults, low-income families, people living in rural areas and adults with a high school education or less. Living in a neighborhood where it is safe to exercise outdoors and being able to access affordable, healthy foods are linked to a reduced risk of developing obesity.

Lifestyle and environmental factors, including shift work, noise pollution and nighttime light exposure, can also increase this risk by interfering with circadian rhythms and affecting sleep quality and duration. A 2025 American Heart Association scientific statement about circadian health highlighted that disruptions to the body’s internal clock are strongly associated with an increased risk of obesity, Type 2 diabetes, high blood pressure and cardiovascular disease.

Barriers to seeking and accessing care

Despite greater availability of treatment options for obesity, including weight management programs focused on lifestyle changes and medications such as GLP-1 receptor agonists, there are still significant challenges in effectively treating obesity.

Weight stigma perpetuates harmful attitudes: Previous research has found that between 20% and 90% of people have negative and judgmental opinions about people with excess weight, such as, obesity is a personal lifestyle choice or a reflection of poor self-control. These perceptions may contribute to poor mental health as well as unhealthy eating behaviors. Experiences of weight stigma can also make individuals more likely to avoid seeking care and support from health care professionals. Individuals with obesity face physical and financial challenges in the health care system: Physical barriers, such as medical equipment and small spaces, often discourage people with obesity from seeking medical care to help them manage their weight. Other barriers to accessing obesity care include the cost of co-pays or other out-of-pocket costs, transportation challenges and limitations in health insurance coverage. Time is an often-overlooked barrier: Limited time directly affects an individual’s ability to participate in obesity prevention and treatment programs. In addition, work and caregiver responsibilities are often prioritized to maintain financial and household stability, thereby reducing the amount of time available to support healthy lifestyle behaviors, such as preparing healthy meals at home and engaging in regular physical activity. A multifaceted approach is necessary

Effective obesity prevention and treatment programs include collaboration among government, health care professionals, community organizations and individuals. Community-based interventions, such as faith-based and cultural programs, are effective and may improve outcomes across different populations. However, the statement notes that the available metrics for gauging intervention success, such as body mass index (BMI), do not accurately reflect body fat or overall health. The development of more clinically meaningful metrics will be necessary to advance efforts in reducing obesity rates and promoting healthy weight for people of all ages.

In addition, health care professionals can make a significant impact by initiating culturally sensitive discussions with patients around their beliefs about weight and care, offering referrals to local resources and providing personalized care to support patients. Educating health care professionals about biases may also help to reduce weight stigma in health care settings.

“The most effective weight management programs are culturally and socially informed and involve stakeholders from across all levels of society working together to support people at risk for or living with obesity. Improving the affordability of fruits and vegetables specific to cultural diets, increasing access to healthy weight management programs, promoting physical activity and advocating for public policies such as insurance coverage of obesity medications, are key strategies that could have large societal impacts,” Stanford said.

Maternity baby deaths much higher in northern England than in the South

2026-01-15

A new paper in the Journal of Public Health, published by Oxford University Press, indicates that maternity services in the North of England most consistently report higher-than-average rates of perinatal mortality, including stillbirths, compared to those in the South. The year 2025 marked the end of a decade-long UK government national maternity safety initiative, which aimed to halve the rate of stillbirths, neonatal and maternal deaths and brain injuries occurring during or soon after birth. While this was not achieved, a 36% reduction in perinatal ...

Mosquitoes’ thirst for human blood has increased as biodiversity loss worsens

Stretching along the Brazilian coastline, the Atlantic Forest is home to hundreds of species of birds, amphibians, reptiles, mammals, and fishes. However, due to human expansion, only about a third of the forest’s original area remains intact. As human presence drives animals from their habitats, mosquitoes that once fed on a wide variety of hosts might be finding new, human targets to quench their thirst for blood, a new Frontiers in Ecology and Evolution study found. “Here we show that the mosquito species we captured in remnants ...

Electrospinning for mimicking bioelectric microenvironment in tissue regeneration

2026-01-15

Background Various tissues and organs in the human body, such as nerves, heart, bones, and skin, rely on bioelectrical signals to maintain function and support regeneration. Although conventional electrical therapies are effective, they require external power sources and invasive electrodes, leading to high risks of infection and reduced patient comfort. This review innovatively proposes the use of electrospinning to fabricate electroactive fibrous scaffolds, which mimic the structure of the extracellular matrix while providing electrical activity, thereby enabling non-invasive and self-powered tissue repair. Research Progress Electrically sensitive ...
