The body mass index (BMI) isn't a perfect measure for obesity. Convenience and routine are on its side -- so health experts aren't likely to stop using it any time soon -- but its limitations have got some doctors thinking ÃÂÃÂ
. In a study published online Monday in the journal Pediatrics, researchers at the University of Michigan's Mott Children's Hospital found measurements of neck circumference to be a reliable technique...

The health benefits of breast-feeding for mothers and babies are widely known. Studies have shown it may improve cognitive development among children and could reduce a woman's risk of getting breast cancer or cardiovascular disease. But new research suggests that some very obese woman may not breast-feed as much or for as long as their normal-weight counterparts. The study, released in the January issue of the journal Obesity, looked at information about 3,517 white women and 2,846 black women from 2000 to 2005.

Americans have increased their life expectancy by cutting back on cigarettes, but the pounds they're packing on mean that, ultimately, they could lose ground. A New England Journal of Medicine study published Wednesday looked at previous national health surveys to forecast life expectancy and quality of life for a typical 18-year-old from 2005 through 2020. Declines in smoking over the last 15 years would give that 18-year-old an increased life expectancy of 0.31 years. However, growing body mass index rates would also mean that that teen would have a reduced life expectancy of 1.02 years, giving a net life expectancy reduction of 0.71 years.

The South tips the scales again as the nation's fattest region, according to a new survey by the Centers for Disease Control and Prevention in Atlanta. More than 30% of adults in Mississippi, Alabama and Tennessee are considered obese. In part, experts blame Southern eating habits, poverty and demographic groups that have higher obesity rates. Colorado was the least obese, with about 19%. Nationwide, about 26% of adults were obese. Obesity is based on the body mass index, a calculation using height and weight.

To maintain your weight as you enter the new year -- or any time -- slow down and savor your food. That's the message from a new study that suggests slow eaters are less likely to add weight than those who quickly gobble their meals. Researchers have long suspected that eating fast might play a role in weight gain. But few studies have systematically examined the effects of eating quickly in healthy adults, and those results were mixed.

Compare athletes in a sprint event to those running a marathon and it's obvious that a runner's body doesn't take one shape -- sprinters tend to have muscular builds, and distance runners are more wiry. The key to the differences, according to a new research study, may lie in a runner's body mass index. Runners' abilities have long been measured via how much oxygen they can deliver to the muscles, but that doesn't tell the whole story of why their physiques differ so greatly.

To reach a healthier weight this summer, consider throwing some Portobello mushrooms, veggie burgers and fish on the grill in place of the usual steak, hot dogs and chicken. A new study of about 55,000 healthy, middle-aged Swedish women finds that vegetarians of all types weighed significantly less than their meat-eating counterparts. The findings are some of the first to show a direct link between a plant-based diet and a lower body mass index.

Critically injured accident victims are more likely to die or have worse outcomes if they are obese, researchers have reported, although the reasons aren't exactly clear. A study of 242 patients admitted to L.A. County and USC Medical Center's critical care and trauma unit in 2002 showed that those with body mass indexes of 30 or higher were twice as likely to die as their thinner counterparts: 32% of the obese patients died compared with 16% of those at lower weights.

Physical education class has long suffered from an image problem. Children often deem jumping jacks and chin-ups boring or goofy; parents wonder if the time would be better spent on reading skills. But a new study makes a strong case that physical education may be the single best strategy for curbing the nation's growing child obesity problem -- at least among girls. In the first study to evaluate the effect of P.E.

President Bush and I have several things in common. We run dozens of miles per week; we have similar 5K race times; we are in excellent overall health; we are perceived as trim by most nonanorexic observers; and we are both dangerously overweight, according to the U.S. public health establishment. The president and I are weighed down by body mass index figures above 25.
