How big is too big?
To check your girth, wrap a tape measure around your waist at the navel. No fair sucking in your bulge. Men should have a waist circumference no larger than 40 inches. For women, the limit is 35 inches.
The new study, appearing in Monday's Archives of Internal Medicine, is the first to analyze waist size and deaths for people in three BMI categories: normal, overweight, and obese. In all three groups, waist size was linked to higher risk.
About 2 percent of people in the study had normal BMI numbers but larger than recommended waists. Jacobs said the risk increased progressively with increasing waist size, even at waist sizes well below what might be considered too large.
The study used data from more than 100,000 people who were followed from 1997 to 2006. Nearly 15,000 people died during that time.
The researchers crunched numbers on waist circumference, height, and weight to draw conclusions about who was more likely to die. Study participants measured their own waists, so some honest mistakes and wishful fudging could have been included, the authors acknowledged.
Four extra inches around the waist increased the risk of dying from between 15 percent to 25 percent. Oddly, the strongest link — 25 percent — was in women with normal BMI.
People with bigger waists had a higher risk of death from causes including respiratory illnesses, heart disease, and cancer.
The study was observational, a less rigorous approach that means the deaths could have been caused by factors other than waist size. But the researchers did take into account other risk factors for poor health, such as smoking and alcohol use. Story continues ...
