Causes of Death Are Linked to a Person’s Weight

By GINA KOLATA
About two years ago, a group of federal researchers reported that overweight people have a lower death rate than people who are normal weight, underweight or obese. Now, investigating further, they found out which diseases are more likely to lead to death in each weight group.

Linking, for the first time, causes of death to specific weights, they report that overweight people have a lower death rate because they are much less likely to die from a grab bag of diseases that includes Alzheimer’s and Parkinson’s, infections and lung disease. And that lower risk is not counteracted by increased risks of dying from any other disease, including cancer, diabetes or heart disease.

As a consequence, the group from the Centers for Disease Control and Prevention and the National Cancer Institute reports, there were more than 100,000 fewer deaths among the overweight in 2004, the most recent year for which data were available, than would have expected if those people had been of normal weight.

Their paper is published today in the Journal of the American Medical Association.

The researchers also confirmed that obese people and people whose weights are below normal have higher death rates than people of normal weight. But, when they asked why, they found that the reasons were different for the different weight categories.

Some who studied the relation between weight and health said the nation might want to reconsider what are ideal weights.

“If we use the criteria of mortality, then the term ‘overweight’ is a misnomer,” said Daniel McGee, professor of statistics at Florida State University.

“I believe the data,” said Dr. Elizabeth Barrett-Connor, a professor of family and preventive medicine at the University of California, San Diego. A body mass index of 25 to 30, the so-called overweight range, “may be optimal,” she said.

Others said there were plenty of reasons that being overweight was not desirable.

“Health extends far beyond mortality rates,” said Dr. JoAnn Manson, chief of preventive medicine at Brigham and Women’s Hospital in Boston.

Dr. Manson added that other studies, including ones at Harvard, found that being obese or overweight increased a person’s risk for any of a number of diseases, including diabetes, heart disease and several forms of cancer. And, she added, excess weight makes it more difficult to move about and impairs the quality of life.

“That’s the big picture in terms of health outcomes,” Dr. Manson said. “That’s what the public needs to look at.”

Researchers generally divide weight into four categories — normal, underweight, overweight and obese — based on the body mass index, which is a measure of body fat based on height and weight. A woman who is 5 foot 4, for instance, would be considered at normal weight at 130, underweight at 107 pounds, overweight at 150 pounds and obese at 180.

In this study, those with normal weight were considered the baseline and others were compared to them.

The federal researchers, led by Katherine Flegal, of the Centers for Disease Control and Prevention, said the big picture they found was surprisingly complex. The higher death rate in obese people, as might be expected, was almost entirely driven by a higher death rate from heart disease.

But, contrary to expectations, the obese did not have an increased risk of dying from cancer. They were slightly more likely than people of normal weights to die of a handful of cancers that are thought to be related to excess weight — cancers of the colon, breast, esophagus, uterus, ovary, kidney and pancreas. Yet they had a lower risk of dying from other cancers, including lung cancer. In the end, the increases and decreases in cancer risks balanced out.

As for diabetes, it showed up in the death rates only when the researchers grouped diabetes and kidney disease as one category. Diabetes can cause kidney disease, they note. But, the researchers point out, the number of diabetes deaths may be too low because many people with diabetes die from heart disease, and often the cause of death is listed as a heart attack.

The diverse collection of diseases other than cancer, heart disease and diabetes, which show up in the analyses of the underweight and the overweight, have gone relatively unscrutinized among epidemiologists, noted Dr. Mitchell Gail, a cancer institute scientist and an author of the paper. But, Dr. Gail added, “these are not a negligible source of mortality.”

The new study began several years ago when the investigators used national data to look at death risks according to body weight. They concluded that, compared with people of normal weight, the overweight had a decreased death risk and the underweight and obese had increased risk.

That led them to ask if being fat or thin affects a person’s life span, what diseases, exactly, are those individuals at risk for, or protected from?

The research involved analyzing data from three large national surveys, the National Health and Nutrition surveys, which are administered by the National Center for Health Statistics. Their participants are a nationally representative group of Americans who are weighed and measured, assuring that heights and weights are accurate, and followed until death. The investigators determined the causes of death by asking what was recorded on death certificates.

The researchers caution that a study like theirs cannot speak to cause and effect. They do not yet know, precisely, what it is about being underweight, for instance, that increases the death rate from everything except heart disease and cancer. Researchers tried to rule out those who were thin, because they might have been already sick. They also ruled out smokers, and the results did not change.

Dr. Gail, though, had some advice, which, he said, is his personal opinion as a physician and researcher: “If you are in the pink and feeling well and getting a good amount of exercise and if your doctor is very happy with your lab values and other test results, then I am not sure there is any urgency to change your weight.”

There are so many studies on what causes you to live longer, and what causes health problems. The reality is that EVERYTHING causes health problems, and EVERYTHING protects other health problems. The article proved it - it stated that being overweight helps protect alzheimers and parkinsons and things like that, but other studies say it increases risk of heart disease. Therefore, not being overweight decreases the risk of heart disease, but doesn't help protect you from alzheimers and parkinsons......

The only thing to do is pick which one you want to be - big or skinny. After that, just have fun, toke some cheeb, and bang some hot girls (if thats your thing). Some bad s*** is gonna happen to you somewhere along the way, so you'd better make the best out of it while you can.

Ermm... hate to bring this up, but simply "overweight" doesn't cut it. Go Obese or go home.

Funny, I once read a research article from the NY Times (same paper you quoted) that discussed how CR, controlled restriction (chronic under eating of only healthy foods), elongates life. Take many, if not all things with a grain of salt.

Dude, if I believed what I read, I'd be listening to you skinny people trying to tell me how to get big and strong. I just find it funny in our society of gay abercrombie, metrosexuals that fat is now, ok. I love it.

In 2 years, this article will be replaced with another article that's on the complete opposite end of the spectrum from where it is now. There's never any middle ground in the fitness industry.
