Study: Overweight or obese can make a longer lifespan
But not too overweight.
Apparently a few pounds weight gain is not a bad thing. Studies conducted recently said, when nearly three million people who are slightly overweight or obese can live longer.
But experts warned then, the benefits it will drop sharply when the weight is increasing and uncontrolled.
Conclusion weight is associated with better health experts called the paradox of obesity, although obesity is generally not associated with “benefits”.
The researchers used data from 100 studies around the world to gather health information of approximately 2.8 million adu*ts.
From these samples, there are about 270 thousand deaths during the study goes. Even after stratifying factors such as age, gender, smoker. Those who have a body weight that is rated “overweight”, six percent had a lower risk of death compared to samples that had normal weight.
And people are a little fat with equal height and weight, gave a BMI of 30 to 35, only five percent risk of dying within a given period.
But for those who are overweight with a BMI value of 35, the mortality rate rose to 29 percent compared to a normal weight. results of the study written in the Journal of the American Medical Association.
BMI is body mass index, calculated based on the ratio of body weight in units of kilograms and height in meters, squared.
The authors suggested several possible reasons have more fat weight it was good, but it would be bad if it is not controlled.
The reason, increased body fat will increase the metabolic benefits that protect the heart and has extra reserves of fat to help cure the disease of patients who are difficult to eat.
Head of the study, Katherine Flegel from the U.S. Centers for Disease Conrol and Prevention or CDC, also published a controversial study in 2005 that showed no link between excess weight and live longer.
This time the analysis is based on field samples a much larger amount, which in many countries in North America, Europe, Asia, and South America.
Other studies also indicate if a bit excessive fat can provide energy reserves needed for pain or help in other ways that are still being studied. It is listed in the research Steven Heymsfield and William Cefalu in an editorial also published Tuesday in JAMA.
“Not all patients were classified as grade 1 overweight, particularly those with chronic diseases, requires maintenance of weight,” he said.
“We still have much to learn about obesity, including how best to measure it,” said CDC director Thomas Friedan said in a statement.
“But obviously, obesity is unhealthy, thus increasing the risk of diabetes, heart disease, cancer, and a host of other health problems,” he added.
According to statistics issued by the CDC, one-third of adu*ts in the United States are obese.
