Even those of normal weight had greater risk of death if belly was big
CHICAGO – If your pants are feeling a bit tight around the waistline, take note: Belly bulge can be deadly for older adults, even those who aren’t overweight or obese by other measures.
One of the largest studies to examine the dangers of abdominal fat suggests men and women with the biggest waistlines have twice the risk of dying over a decade compared to those with the smallest tummies.
Surprisingly, bigger waists carry a greater risk of death even for people whose weight is “normal” by the body mass index, or BMI, a standard measure based on weight and height.
“Even if you haven’t had a noticeable weight gain, if you notice your waist size increasing, that’s an important sign,” said lead author Eric Jacobs of the American Cancer Society, which funded the study. “It’s time to eat better and start exercising more.”
Other research has linked waist size to dementia, heart disease, asthma and breast cancer.
Bulging bellies are a problem for most Americans older than 50. It’s estimated that more than half of older men and more than 70 percent of older women have bigger waistlines than recommended. And it’s a growing problem: Average waistlines have expanded by about an inch per decade since the 1960s.
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 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.
Some scientists believe belly fat secretes proteins and hormones that contribute to inflammation, interfere with how the body processes insulin and raise cholesterol levels.
But Dr. Samuel Klein, an obesity expert at Washington University School of Medicine in St. Louis, is skeptical about that theory. Removing belly fat surgically doesn’t lead to health improvements. That may mean it’s simply a stand-in for some other culprit that is causing both belly fat and poor health. Klein wasn’t involved in the new research.
What can be done to fight belly fat? It’s the same advice as for losing weight. Eat fewer calories and burn more through aerobic exercise. “Sit-ups are useless,” Klein said.
