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 budding worldwide dissection 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 division noted long hair ke upay. "For population with a medical condition, survival is degree better for people who are slightly heavier," said study author Katherine Flegal, a older research scientist at the US Centers for Disease Control and Prevention's National Center for Health Statistics.



Several factors may significance for this finding. "Maybe heavier people present to the doctor earlier, or get screened more often. Heavier tribe 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 standpoint a shock to their system" products. the report was published jan. 2 in the Journal of the American Medical Association.



For the study, Flegal's gang collected data on more than 2,88 million relations 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 group index, or BMI, which is a mensuration of body fat that takes into estimation a person's height and weight. Pooling the data from all the studies, the researchers found that compared with normal importance people, overweight people had a 6 percent lower risk of death.



Obese people, however, had an 18 percent higher hazard of death. For those who were the least obese, the risk of ruin 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 go into found an association between weight and premature annihilation risk, it did not prove a cause-and-effect relationship.



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



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



There is a case to be made that a body miscellany index in what is now considered the overweight range might be redefined as normal. "If weight is not damaging 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 snowball the risk of such conditions as type 2 diabetes, or medication use for cardiac imperil factors, without increasing mortality. This study would be blind to such effects".



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