Release date: 2014-07-11 With the improvement of people's living standards and changes in lifestyle and diet, obesity has encountered severe conditions in the world. The World Health Organization, WHO has positioned it as an important disease, and it is listed as an important public health problem worldwide. Previous studies have shown that people with moderate obesity have a longer life expectancy, and this view has been greatly questioned. There has been a lot of debate about the relationship between obesity and premature death. Extreme obesity, up to 14 years of life A recent study by 20 large institutions in three countries showed that extreme obesity increases the risk of adult death because they are more prone to health problems such as cancer, heart disease, stroke, diabetes and liver disease. Early death. The study shows that tertiary obesity seems to be the main reason for the early death of countries in the world. In this study, the researchers classified according to the participants' BMI. BMI = weight (Kg) / square of height (M2), BMI classification is as follows: normal weight: 18.5-24.9; excessive weight: 25.0-29.9; primary obesity: 30.0-34.9; secondary obesity: 35.0-39.9; Obesity: ≥40.0 Excluding those who had smoked or had a disease, the researchers assessed the risk of premature death of 9,500 third-degree obese individuals from 304,000 individuals and the specific causes of premature death. They found that The increase in BIM in the tertiary obesity group is also increasing the risk of death. Statistical analysis of the pooled data showed that the excess number of deaths in the tertiary obesity group was mainly due to heart disease, cancer and diabetes. People whose BMI index is between 40 and 44.9 have a life expectancy of 6.5 years, 45 to 49.9 people have lost 8.9 years, 50 to 54.9 have lost 9.8 years, and 55 to 59.9 have lost life of 13.7 years. Research on the same point of view Although the researchers said that the accuracy of the results is limited by two aspects, first, the weight and height used in the study are reported by the individual, and the second is to determine obesity only by a means of BMI. But before that, there have been many related studies supporting the idea of ​​“obesity reduction theoryâ€. Researchers at the National Institutes of Health, the National Cancer Institute, and the American Association of Retired Persons conducted a study of 500,000 volunteers aged 50 to 71 in the United States. They found that just overweight can cause health damage. The researchers used a questionnaire to analyze the relationship between body index and mortality during these 10 years. An independent analysis of 186,000 people who never smoked but overweight showed that they were 20 years older than those with normal weight. %-40% Researchers at Yonsei University in South Korea and the Bloomberg School of Public Health at Johns Hopkins University in the United States conducted similar studies on 1,200,000 to 30-year-old Koreans. Among the approximately 500,000 non-smokers, overweight people are 10%-50% more likely to die of heart disease and cancer than normal weight. Another study, completed by the Harvard School of Public Health, was published in the New England Journal of Medicine. The researchers selected more than 114,000 patients with type 2 diabetes from the US Nurses Health Status Tracking Survey and Health Care Professional Follow-up Survey, with an average age of 62 years. A total of nearly 3,100 patients died during the follow-up period of nearly 16 years. The study found that patients with too low and too high BMI had significantly increased mortality compared with patients with normal body mass index (BMI) at the time of diagnosis of diabetes. Among them, the greater the body mass index, the higher the risk of premature death. Opposite sound Different from the "obesity reduction theory", there have been reports that a US expert conducted a research experiment and found that if a person's weight is overweight, his life expectancy will be longer. The researchers explained that a stable weight has a large impact on the length of life. After the age of 51, people who weigh more than 1 to 6 kg of normal body weight, but who maintain a relatively stable weight, are less ill and have lower mortality. In the past 30 years, no country has succeeded in reducing the proportion of obese people in the national population. The proportion of obese people in the world's population has been growing. If countries with a high proportion of obese people do not take measures to solve such problems, they may face a very serious public health crisis in the future.
