The Presence Of A Few Extra Pounds In Man Reduces The Risk Of Sudden Death

The Presence Of A Few Extra Pounds In Man Reduces The Risk Of Sudden Death.

A further or oecumenic study reveals a surprising pattern: while obesity increases the risk of dying early, being slightly overweight reduces it. These studies included almost 3 million adults from around the world, yet the results were remarkably consistent, the authors of the critique noted "For men and women with a medical condition, survival is somewhat better for people who are slightly heavier," said study author Katherine Flegal, a chief research scientist at the US Centers for Disease Control and Prevention's National Center for Health Statistics.

Several factors may benefit for this finding. "Maybe heavier people present to the doctor earlier, or get screened more often. Heavier settle may be more likely to be treated according to guidelines, or fat itself may be cardioprotective, or someone who is heavier might be more resilient and better able to remain in effect a shock to their system" product. the report was published jan. 2 in the Journal of the American Medical Association.

For the study, Flegal's group collected data on more than 2,88 million rank and file included in 97 studies. These studies were done in the United States, Canada, Europe, Australia, China, Taiwan, Japan, Brazil, Israel, India and Mexico. The researchers looked at the participants' body piles index, or BMI, which is a amplitude of body fat that takes into narration a person's height and weight. Pooling the data from all the studies, the researchers found that compared with normal bias people, overweight people had a 6 percent lower risk of death.

Obese people, however, had an 18 percent higher imperil of death. For those who were the least obese, the risk of liquidation was 5 percent lower than for normal weight people, but for those who were the most obese the risk of death was 29 percent higher, the findings revealed. While the boning up found an association between weight and premature cessation risk, it did not prove a cause-and-effect relationship.

Indeed, one expert cautioned that body weight alone cannot predict fitness and the risk of death. "There are other factors that play a role in overall health," said Dr William Cefalu, superintendent and professor of the section of endocrinology, diabetes and metabolism at Louisiana State University and co-author of an accompanying annual editorial. "Body mass index simply is a parameter; it doesn't carry off into consideration family history, it doesn't take into consideration smoking, fitness, cholesterol and other factors that should be considered beyond body lion's share index".

Another expert agreed and added that the issues around body weight are more complex than this study suggests. "This is a large, sophisticated and statistically powerful study that shows convincingly that more dour degrees of obesity increase the risk of premature death, while being merely overweight does not," said Dr David Katz, the gaffer of the Yale University Medical School Prevention Research Center. "Like the swatting itself, the messages here are a bit complex".

There is a case to be made that a body lump index in what is now considered the overweight range might be redefined as normal. "If weight is not dangerous to health, there is no reason to suggest otherwise".

This study, however, looks only at death, not chronic medical conditions. "It may well be being overweight does augmentation the risk of such conditions as type 2 diabetes, or medication use for cardiac gamble factors, without increasing mortality. This study would be blind to such effects".

Katz also noted the trends in embonpoint may be tipping the scale toward increased risk of dying. "Rates of overweight and obesity overall appear to be stabilizing, while rates of life-threatening obesity are rising briskly". This study suggests being overweight and left so might offer health advantages, "but moving from overweight to obese, and from obese to more obese, is a important peril and many in the population are doing exactly that," Katz pointed out single. "By clarifying the thresholds at which avoirdupois poses a threat of premature death, this study invites us to concentrate our efforts there".
