Your waist size may be more important than weight for heart attack risk

It’s been known for a while that having a pot belly, even if you are slim elsewhere, increases the odds of having a first heart attack, The link was particularly strong in men, researchers said.

A study found that belly fat was associated with heart attacks and stroke independent of other risk factors like smoking, diabetes, hypertension, body mass index and prevention treatments. The researchers stressed that waist circumference was a more important marker than overall obesity and advised doctors to measure their patient’s waists to identify those at risk. Most patients — 78% of men and 90% of women — had abdominal obesity, defined as a waist circumference of 94 cm (37.6 inches) or above for men, and 80 cm (32 inches) or above for women.

However, they said that the link was stronger and more linear in men, who made up nearly three-fourths of the patients included in the study, than women.

In women, Dr. Hanieh Mohammadi said the relationship was “U-shaped” rather than linear, meaning that the mid-range waist measurement, rather than the narrowest, was least risky. What’s more, the mid-range waist measurement was in the range traditionally recognized as at risk for abdominal obesity: more than 80 cm wide.

The reason for this could be down to the type of fat that tends to hang out on men’s and women’s bellies. Mohammadi said some studies have suggested that men may have more visceral fat that goes deep inside your body and wraps around your vital organs.
This fat can be turned into cholesterol that can start collecting along and hardening your arteries, perhaps ultimately leading to a heart attack or stroke.
“In women it is thought that a greater portion of the abdominal fat is constituted by subcutaneous fat which is relatively harmless,” she said.

However, the lower numbers of women included in the study meant the findings had less “statistical power” and more research was needed to draw definite conclusions, Mohammadi said.

The risk of cardiovascular disease like heart attacks or strokes is considered to be higher in those with a waist measurement of above 94 cm in men and above 80 cm in women, according to the World Health Organization. The risk is thought to be substantially increased in men with a waist wider than 102 cm and 88 cm in women.
The authors said that belly fat was best tackled by a healthy diet and regular exercise. Earlier studies have shown that regular moderate cardio, like walking for at least 30 minutes a day, can help fight a widening waistline. Strength training with weights may also help but spot exercises like sit-ups that can tighten abs won’t touch visceral fat.
