Recent research suggests waist size can offer crucial insights into heart health, potentially more than weight alone. A study assessed waist measurements as indicators of cardiovascular risks, which might not be visible when relying solely on BMI.
The Cross-Cohort Collaboration analyzed data from nearly 260,000 adults involved in 15 long-term health studies over two decades. Findings published in the Journal of the American College of Cardiology indicate individuals with normal weight by BMI can still have significant abdominal fat.
“BMI only informs about weight relative to height and doesn’t specify fat storage locations, which are important,” said Erin Palinski-Wade, a dietitian.
Research observed that higher waist measurements or waist-to-hip ratios among those with normal or overweight BMI correlated with a 15% to 50% increased risk of heart-related issues and mortality. Hence, assessing weight distribution across the body might prove more effective.
Additional findings show visceral fat around abdominal organs is more metabolically active, driving inflammation, insulin resistance, and arterial damage unlike subcutaneous fat. The study emphasizes knowing where fat is stored may be more vital for heart health than overall body weight.
Multiple health outcomes were reviewed, including heart attacks, strokes, and cardiovascular deaths. Researchers acknowledged limitations like the lack of data on participants’ activity levels, diets, or genetic obesity risks, all impacting cardiovascular health.
The study’s measurements were taken only once, constraining insights into how abdominal fat alterations over time might affect heart disease risk.
