Waist Measurements Reveal Heart Risk
A new study suggests that waist measurements may reveal more about cardiovascular health than body weight alone. Researchers say abdominal fat can remain hidden, even when someone has a body mass index (BMI).
The Cross Cohort Collaboration reviewed data from nearly 260,000 people. They came from 15 medical studies and had follow-up periods lasting almost 20 years. The findings appeared in the Journal of the American College of Cardiology.
Larger waists linked to risk
Researchers found that larger waist sizes and higher waist-to-hip ratios were linked with greater risks. These measures were associated with a 15% to 50% risk of cardiovascular conditions and death.
The study examined heart attacks, strokes, heart failure and atrial fibrillation. It also examined cardiovascular deaths. Therefore, the results suggest that body shape may offer clues about heart health.
Abdominal fat may matter
BMI measures weight against height. However, it cannot show where fat is stored in the body. Deep abdominal fat surrounds internal organs and may affect health.
Experts link this type of fat with inflammation, insulin resistance and blood vessel damage. As a result, waist measurements may provide extra information when assessing risk.
Researchers said people with normal or overweight BMI levels could still carry abdominal fat. Therefore, relying on BMI alone may miss risk factors.
Study has some limitations
The researchers noted limitations. They lacked information about physical activity, diet and genetic factors linked with obesity.
In addition, researchers measured waist size and waist-to-hip ratios only once. This means the study could not fully assess how changing abdominal fat affects cardiovascular risk over time.
The findings do not mean waist size alone can predict health. Instead, they suggest healthcare professionals may benefit from considering several measures together. A balanced diet, regular exercise and routine health checks can support heart health.
