Neck Size Linked to Heart Risk
Study Shows Neck Fat Increases Risk of Heart Disease
March 11, 2009 -- As your collar size grows, so does your risk of heart
It's true for both men and women: Neck fat adds to your risk of heart
disease, over and above the known heart risk from belly fat.
The finding comes from data collected from 3,320 people in two studies of
heart disease risk factors.
Belly fat -- specifically, fatty deposits around the organs of the central
body -- is known to increase the risk of heart disease. Sarah Rosner Preis,
ScD, MPH, and colleagues theorized that upper-body fat, as measured by neck
circumference, also raises heart risk.
Sure enough, they found that the bigger a person's neck size, the greater
that person's risk of high levels of LDL "bad" cholesterol and blood
fat, insulin resistance, and high blood sugar. This held true even after
controlling for belly fat.
Rosner Preis and colleagues reported the findings at this week's American
Heart Association (AHA) meeting.
