July 13, a study published in the "Lancet" (The Lancet) magazine confirmed that overweight or obesity and increased risk of premature death are closely related. In Europe and North America, obesity has become the second largest cause of premature death reasons, second only to tobacco.
The first author of the paper, Dr. Emanuele Di Angelantonio University of Cambridge, said: "On average, people's actual life overweight can shorten life expectancy than about 1 year, and moderately obese people than actual life will shorten the life expectancy of about 3 years in addition, obese men is higher than the risk of premature death in obese women. "
This study brings together 189 studies from Europe, North America and other parts of the previously published, involving more than 3.9 million adults. Older adults to participate in these studies were between 20 years to 90 years. During the study period, they do not smoke, and do not have any chronic diseases. Research has lived at least five years people were analyzed, 3,951,455 participants in 385,879 deaths.
Large differences between men and women
Premature death Age authors defined as 35-69 years old. The study found that as BMI (Body Mass Index, BMI) increases the risk of premature death also will be a sharp increase of.
Risk BMI normal men and women at 70 years before death (premature death) were 19% and 11%; the risk of moderate obesity (BMI 30-35) male and female premature death and rose to 29.5%, respectively 14.6%. In other words, moderately obese men the risk of premature death increased by 10.5%, while the risk of premature death moderately obese women increased by 3.6%.
Dr. Emanuele Di Angelantonio said: "This is consistent with the results of some previous studies compared with obese women, obese men insulin resistance, liver fat levels and a higher risk of developing diabetes.."
Second only to the harm of smoking
Co-author of the study, Professor Sir Richard Peto of Oxford University, said: "In Europe and North America, obesity has become the second largest cause of premature death reasons, second only to tobacco."
Specifically, in Europe and North America, about a quarter of premature deaths caused by smoking. However, smokers can be halved by quitting the risk of premature death. Worthy of attention is currently in Europe, about one seventh of premature deaths are caused by the overweight and obese. In North America, this proportion has reached one-fifth.
How to reduce the impact?
For this study, WHO experts said they believe that the establishment of a mature Childhood Intervention (childhood intervention) is the key to worldwide significantly reduce obesity-related mortality. Overweight and obesity are largely preventable. In addition, some experts said that the current obesity epidemic is still in development, all regions of the world should give attention to this issue.
Finally, it is worth noting that the authors pointed out that this study has an important limitation that they just measured obesity by BMI, and did not assess the different parts of the body fat distribution, muscle mass or obesity-related metabolic factors, such as blood sugar or cholesterol.
