Those with normal weight but a larger belly have more chances of having heart problems than those who are overweight but do not wear their overweight around the waist.
Researchers tested the hypothesis that people with normal weight and central obesity had more heart problems than people with normal weight and normal fat distribution
It comes after concerns that Body Mass Index (BMI) is weight-to-height and is used to categorize adults as underweight, normal weight, overweight or obese, failing to account for the amount and distribution of fat and muscle.
From 1997 to 2000, the study enrolled 1,692 American residents of Olmsted County, Minnesota, aged 45 or older.
Participants underwent clinical examination and measurements of weight, height, waist circumference and hip circumference.
They were then screened for the occurrence of severe cardiovascular events from 2000 to 201
It turned out that participants with a normal BMI and central obesity had about twice the long-term risk of suffering from cardiovascular disease serious cardiovascular event, when the results were compared with participants without central obesity, regardless of their BMI.
