The earth is really not 'friendly' to fat people. Two days ago, Science reported that Google's Deepmind AI can use satellite positioning to identify fat people (for public health research). Turning the head, "Lancet" made another An article that announces that fat people are more likely to have major illnesses than ordinary people, and that they are more ill and longer-
Research on The Lancet
The major diseases here include: type 2 diabetes, coronary heart disease, cancer, stroke, chronic obstructive pulmonary disease and asthma.
The Lancet study included a sample of 137,503, consisting of 10 research groups. They not only analyzed the odds of people with different BMIs who developed major chronic diseases after they reached middle age, but also calculated that these people would be averaged How many years have you been ill?
In order to make the study more comprehensive, they also added three other factors to evaluate: money, smoking, physical activity.
Obese people can be sick for 8 years
According to the World Health Organization classification criteria, the researchers divided the participants into 5 groups according to BMI, namely: underweight group (BMI) < 18.5kg/㎡) , 体重正常组 (25kg/㎡> BMI≥18.5kg/m2), super-recombination (30kg/m2> BMI≥25kg/m2), mild obesity group (35kg/m2>BMI≥30kg/m2), severe obesity group (BMI≥35kg/m2).
It should be noted that the more than 130,000 volunteers participating in the study are all Europeans. Due to their different physical qualities, in the BMI division, some institutions have separately set a set of East Asian standards applicable to countries such as China, Japan and Korea. In the standard, the threshold for overweight and obesity is lower than the WHO standard.
Through statistics, the researchers found the following rules -
For men, as long as they are not normal BMI, after the year (40-75 years old), they will have a major illness and will live longer than normal BMI, including lower than normal weight.
Men in the normal BMI group had an average disease-free survival of 29.3 years in these 35 years. Compared with the normal group, the low body reorganization was 1.8 years more sick, the super-recombinant disease was 1.1 years, and the mild obesity group was more 3.9. In the year, the severely obese group was 8.5 years old.
But women are amazing in this respect. Middle-aged women with low body reorganization will not only reduce their healthy life expectancy, but also slightly more.
Women in the normal BMI group had an average disease-free survival of 29.4 years, and women with low body reorganization had an average disease-free survival of 29.5 years. However, the thin point can be cheaper, and the female is fatter. The duration of the disease was 1.1 years longer than that of the normal group, 2.7 years for the mild obese group and 7.3 years for the severely obese group.
The poorer the more fat, the more smoke
The health effects of our own economic conditions are still very important. In the past, the wealthy people in our minds were all fat, but now, people with good economic conditions are more in control, and more and more fat people are in the poor.
In the above figure, the blue column represents the high-income group, the gray is the middle income, and the red is the low income. The above picture is the male data, the lower picture is the female data. The Y-axis represents the proportion of the attribute in the population, the X-axis They are: obesity, physical activity and current smoking.
According to the researchers, the proportion of obese people in low-income groups is about twice that of high-income groups, and the proportion of smokers is more than that of open-up groups. Especially among women, the proportion of women in low-income groups is about high. Three times the income of the people. Only physical activity, the low-income group is more than the high-income group, but it has not doubled the gap.
All in all, the lower the income, the higher the proportion of obesity and the higher the smoking rate.
Can a rich fat man buy health?
For a slightly fat high-income male, it may be possible...
The above picture is a statistical analysis made by the researchers in combination with economic income and BMI. The left column is male and the right column is female. It can be seen that no matter what kind of economic income, the whole is obeyed. 'This law.
However, for high-income overweight men, their average disease-free survival is slightly longer than that of middle-income and low-income normal BMI men. However, compared with men with the same normal weight, their disease-free survival is still To be shorter.
For women, the difference is much smaller. High-income overweight women do not have more disease-free years of survival than low- and middle-income normal-weight women.
Quit smoking can bend overtaking
No smoking, smoking cessation, even if the weight is higher, the disease-free survival year can also last longer than the smoking population -
The left side is the male data, and the right side is the female data. The upper middle and lower parts are never smoking, have quit smoking, and are smoking.
Men who never smoked with mild obesity (BMI over 30kg/m2) had an average age of disease-free survival that was similar to that of men who smoked normal weight. In female data, the gap was not that large, but the trend was similar.
All in all, no smoking (or quit smoking immediately), weight control is within the normal range, there is a high probability that you can live to 70 years without major illness. Of course, physical exercise is also very important.
