What are the criteria for judging obesity in China's obese provinces?
4hw.org: after the long vacation, are you fat again? Recently, a news report about China's obese provinces has attracted much attention, revealing the current situation of obese people in China. Do you know how to judge whether you are obese or not? Let's have a look with Xiaobian!
According to the latest research, there is a serious obesity epidemic in the world, and the number of obese people in China ranks first in the world
On April 2, the lancet, a medical journal, published a study on obesity around the world. Between 1975 and 2014, the obesity rate in men and women more than doubled. According to the study, China has surpassed the United States as the world's most obese country.
In Sichuan, fat people are not alone. Although the obesity rate is not among the top three in the country, there are many obese people because of the large population base. According to the data released by the health and Family Planning Commission of Sichuan Province, the obesity rate in Sichuan reached 11.1% in 2014, which exceeded the total population of Switzerland, Austria and other countries. From 2005 to 2014, the number of fat people in Sichuan doubled. There are more than 4.7 million new fat people, who can live in several small and medium-sized cities.
Global obesity: the number of global obesity is super thin
The most obese people in China
The study, led by scientists from Imperial College London, shows that in 2014, the global obesity population increased from 105 million in 1975 to 641 million, including 266 million men and 375 million women.
Obesity is not visible to the naked eye, but determined by body mass index. Although there are different clinical definitions of obesity in different regions and countries, generally speaking, if the body mass index is more than 30, it is considered as obesity, and if it is more than 35, it is serious obesity.
Although the number of male obesity is less than that of female, the growth rate of male obesity has been much faster in the past 40 years: the global male obesity rate has increased from 3.2% to 10.8%, while the female obesity rate has increased from 6.4% to 14.9%.
The number of fat people is increasing, while the number of thin people is decreasing. According to the report, from 1975 to 2014, the proportion of underweight men fell from 14% to 9% and that of women from 15% to 10%. That is to say, nowadays, the number of fat people has "bucked" the number of thin people.
The number of fat people is more than that of thin people, so the Chinese people have a lot to do. According to the report, China's obese population exceeds that of the previous "champion" America, ranking first in the world, with 43.2 million obese men and 46.4 million obese women, accounting for 16.3% and 12.4% of the world's obese people, respectively.
Obesity in China: the obesity rate in the north is significantly higher than that in the South
Sichuan has more fat people than Switzerland
Where are the obese people in China? The results of the second periodic study of China's obesity index published in October 2015 give the answer: the obesity rate in the north is significantly higher than that in the south. Among them, Hebei, Inner Mongolia and Xinjiang are in the top three respectively. The three provinces with the lowest obesity rate, Fujian, Zhejiang and Jiangxi, are all in the south.
Wang Jingzhong, a researcher at the Institute of nutrition and health of the Chinese Center for Disease Control and prevention, has previously analyzed that 'fat in the north and thin in the South', in addition to weather factors, is also related to the diet structure. There are too many foods with less grains and high fat and cholesterol, and he likes' drinking a cup ', which makes northern people more prone to obesity.
As for Sichuan, the obesity rate is not the highest, but because of the large population base, there are many obese people here. According to the report on health status and key diseases of Sichuan Population in 2014 issued by Sichuan health and Family Planning Commission in 2015, the obesity rate in Sichuan reached 11.1% in 2014. In other words, one out of 10 Sichuan people is fat.
According to the data of the National Bureau of statistics, in 2014, the total population of Sichuan was 81.4 million, so that the total number of obese people was 9.035 million, more than the total population of Switzerland, Austria and other countries.
The obesity rate in Sichuan has been rising continuously in 9 years
New fat people can live in several cities
In addition to the absolute number, the number of fat people in Sichuan is increasing rapidly. In 2010, the obesity rate of Sichuan adults was 6.7%, an increase of 1.5% over 2005. In 2014, the obesity rate increased by 4.4% to 11.1% on the basis of 2010.
According to the total population of Sichuan, in 2005, there were 82.12 million people in Sichuan, including 4.27 million fat people. By 2014, the total population of Sichuan decreased to 81.4 million, while the number of fat people increased to 9.035 million. On the basis of the reduction of the total population, the number of fat people has doubled, and 4.765 million people have joined the ranks of fat people, which is several times the total population of a small and medium-sized city (less than 1 million). It can be imagined that if the new fat people in Sichuan in recent years are gathered, several small and medium-sized cities will be able to live.
There are more and more fat people in Sichuan. Zhang Yihong, an expert who participated in the investigation of Sichuan national physique and a professor of sports medicine of Chengdu Institute of physical education, said that it is related to the lack of sports and the good food. Eat more fiber content of food, can increase satiety, energy will not be very high. '
Compared with other provinces and cities, Li Xiaohui, executive director of Sichuan nutrition society, believes that Sichuan cuisine's heavy oil and salt is also the 'culprit'. She suggests that adults should not eat more than 6G of salt per day.
