Belly fat linked to heart failure risk even in normal-weight people

Kiswahili

New research shows that visceral fat around the waist increases heart failure risk more than BMI, even among those with normal weight. Inflammation mediates much of this link. The findings were presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026 in Boston.

Researchers presented findings at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026, held in Boston from March 17 to 20, indicating that central obesity or visceral fat raises heart failure risk independently of overall body weight. The study, drawn from the Jackson Heart Study, analyzed data from 1,998 African American adults in Jackson, Mississippi, aged 35 to 84 (average 58), with 36% women. Participants enrolled between 2000 and 2004 without heart failure and were followed for a median of 6.9 years through December 31, 2016. Over this period, 112 developed heart failure. Higher waist circumference and waist-to-height ratio correlated with increased risk, while BMI did not. Blood tests for high-sensitivity C-reactive protein showed that inflammation explained about one-quarter to one-third of the association between abdominal fat and heart failure. Szu-Han Chen, lead author and medical student at National Yang Ming Chiao Tung University in Taiwan, stated: 'This research helps us understand why some people develop heart failure despite having a body weight that seems healthy. By monitoring waist size and inflammation, clinicians may be able to identify people with higher risk earlier and focus on prevention strategies that could reduce the chance of heart failure before symptoms begin.' The work was conducted under Professor Hao-Min Cheng at Taipei Veterans General Hospital and National Yang Ming Chiao Tung University. Sadiya S. Khan, M.D., M.Sc., FAHA, from Northwestern University's Feinberg School of Medicine, commented: 'This study highlights the importance of integrating measures of central adiposity such as waist circumference into routine preventive care.' Researchers noted limitations, including lack of data on heart failure subtypes, and called for further studies on visceral fat's impact on specific types and potential benefits of reducing inflammation.

A proposed update to how obesity is defined—combining body mass index with measures of abdominal fat—would raise the share of U.S. adults classified as having obesity from about 43% to roughly 69%, according to a Mass General Brigham analysis of more than 300,000 participants in the National Institutes of Health’s All of Us Research Program.

Doctors stress abdominal obesity as vital sign in Asian Indians

Experts in India are urging the recognition of abdominal obesity as a new vital sign in Asian Indians to better assess metabolic health risks. An editorial by Amerta Ghosh and Anoop Misra emphasizes the need to measure waist circumference in all patients. This shift addresses the limitations of BMI as a measure of obesity.

New studies highlight body fat's roles in immunity and blood pressure

Imeripotiwa na AI

Recent research shows that body fat is more than a calorie store; it actively regulates immune responses and blood pressure. Scientists have identified specialized fat depots near the intestines that coordinate immunity against gut microbes, while another study links beige fat around blood vessels to vascular health. These findings challenge simplistic views of fat as merely harmful.

Study finds obesity and high blood pressure directly cause dementia

A new genetic study indicates that obesity and high blood pressure directly contribute to dementia, beyond merely raising its risk. Researchers from Denmark and the U.K. used advanced methods to establish this causal link, emphasizing prevention through weight and blood pressure management. The findings suggest early interventions could avert vascular-related dementia.

A new American Heart Association scientific statement published Feb. 25, 2026 in Circulation projects that cardiovascular risk factors such as high blood pressure, obesity and diabetes will become more common among U.S. women by 2050, with particularly steep increases forecast for some younger women and for several racial and ethnic groups.

MIT study reveals high-fat diets boost liver cancer risk

New research from MIT demonstrates that prolonged high-fat diets push liver cells into a primitive state, increasing their vulnerability to cancer. By analyzing mice and human samples, scientists uncovered how these cellular changes prioritize survival over normal function, paving the way for tumors. The findings, published in Cell, highlight potential drug targets to mitigate this risk.
