Washington: Waist circumference is associated with risk of type 2 diabetes, independently of body mass index (BMI), according to a new study.
The results come from a collaborative re-analysis of data from the InterAct case-control study conducted by Claudia Langenberg and colleagues.
The researchers estimated the association of BMI and waist circumference with type 2 diabetes from measurements of weight, height and waist circumference.
They found that both BMI and waist circumference were independently associated with type 2 diabetes risk, but waist circumference was a stronger risk factor in women than in men.
These findings indicate that targeted measurement of waist circumference in overweight individuals could be an effective strategy for the prevention of diabetes because it would allow the identification of a high-risk subgroup of people who might benefit from individualised lifestyle advice.
“Our results clearly show the value that measurement of [waist circumference] may have in identifying which people among the large population of overweight individuals are at highest risk of diabetes,” the researchers said.
The finding was reported in this week’s PLoS Medicine.
