ATLANTA, Aug. 10 (UPI) — U.S. researchers have linked a large waist in women of normal weight to higher risk of death.
Eric Jacobs and other researchers at the American Cancer Society found a larger waist associated with twice the risk of death during the nine-year study period. Waist size increased risk across all categories of body mass index — a measure of body fat using height and weight.
“The reason for the stronger association between waist circumference and mortality among women with low BMI in our study is unclear,” the study authors says in a statement. “Future detailed analyses of the relationship between waist circumference and visceral adipose tissue or measures of insulin resistance within categories of BMI could identify biological reasons for potential differences in the strength of the association between waist circumference and mortality.”
In the study, published in the Archives of Internal Medicine, large waist was defined as larger than 47 inches in men and more than 35 inches in women.
Jacobs and colleagues looked at the association between waist circumference and risk of death among 48,500 men and 56,343 women age 50 and older participating in the Cancer Prevention Study II Nutrition Cohort.
