Is the obesity rate so scary? 40-year global children's obesity increased more than 10 times.
The latest study released by the British Lancet Weekly on the 10th show that last year, the global number of obese children and adolescents up to 124 million, an increase of 10 times more than the 1975 figure (11 million). In some parts of Asia, the number of obese children has accelerated.
The Pacific island countries have the highest obesity rate in the world, and the proportion of obese people among children and adolescents aged 5 to 19 is estimated to exceed 30%. The United States, the Caribbean, and the Middle East have followed closely, with over 20% of obese people of the same age group.
“Over the past 40 years, the global children's obesity rates soar, this trend continued in low-income countries.” The leader of the study, Majid Izzatti, a professor of global environmental health at Imperial College London, said.
Especially in East Asia and South Asia, the number of obese children has accelerated. “In the higher-income countries, the recent obesity rate is at a stable level, but it is still unacceptably high.” Izzatti said. Unlike their grandfathers and grandmothers, “children today begin to gain weight by the age of 5.”
Research partner James Burnham, a statistician at the University of Kent, said: “The average BMI for children in Europe and North America is at a stable level recently, but there is no reason to be complacent.” Of every 5 people in the United States who are 5 to 19 years old, more than one person is obese, compared with 1 in 10 in the United Kingdom.
CNN reported that childhood obesity is likely to continue into adulthood, followed by many health problems, including diabetes, cardiovascular disease and certain cancers.
The World Health Organization is a partner in this research. The agency’s population-based non-communicable disease prevention project officer, Temo Vaccaniaro, noted a “very worrisome trend”. That is, type 2 diabetes that occurs in adulthood begins to appear in children. “Children suffering from type 2 diabetes to pediatric visits, the youngest only 7 years old.”
This study not only focused on obesity but also raised the issue of underweight. Although compared with 40 years ago, the number of children less than the weight of the world has declined, but there are still 192 million children worldwide last year, moderate or severe underweight. For example, in the Indian and Pakistani boys, the proportion of underweight people was 58.1% and 51% respectively, and the girls were 50.1% and 41.6% respectively.
Izzatti considered as important as obesity and underweight problems, but they are often taken apart and talk. Global Dialogue on Obesity Issues “Ignoring malnutrition that has always existed,” The initiatives and donor attention malnutrition did not notice the looming problem of overweight and obesity.
Frank Hu, professor of nutrition and epidemiology at Harvard University’s Chen Zengxi School of Public Health, said: “Over the past 40 years, many countries have experienced “nutrition transformation” with the economic growth, such as India and China.”
At first, obese people appeared in the wealthy class, and the poor class showed a lack of weight. “But when these countries become richer, the opposite trend will occur.” He said, “Because the poor eat cheap, unhealthy food, and the rich choose healthy food.”
Izzatti said that the data show that unhealthy “nutrition transition” will cause underweight people to quickly overweight.
For Frank Hu, the study “wakes the alarm bell”. “Especially in some parts of Asia, their economy is still developing at a high speed, and childhood obesity is also becoming more and more popular.”
With the intensification of the problems of obesity and malnutrition, how can we effectively solve it? The most official answer is sports. I think the latest, the most beneficial is the juggling. Juggling can not only exercise but also increase intelligence.
British scientists have discovered that playing juggling adults such as throwing balls can improve the brain's nervous system and make the brain more flexible. Studies have shown that after receiving handicraft training, the part of the brain related to the movement required to receive the ball will be improved. Even if you stop practicing handicrafts, this phenomenon can still last for several weeks.
People often think that the brain is fixed in adulthood and even begins to degenerate. The fact is that brain structure is likely to still be changed, in order to operate more efficiently and adjust its conduction system.
The white matter of the brain contains many long nerve fiber bundles and is responsible for the transmission of electrical signals between nerve cells. The gray matter is composed of nerve cell bodies, and the brain's information processing and calculation are completed here. Scientists had previously discovered that by learning or experiencing new things, the function of gray matter can be improved, but the white matter's function has never been improved.
In this study, the researchers recruited two groups of 24 adults to perform the experiment. They didn’t know how to throw the ball. One group took a juggling training once a week for six weeks and practiced 30 minutes a day. Both groups of subjects underwent brain magnetic resonance imaging before and after the experiment. After the participants received training, there was a huge difference in skill levels. They all can throw 3 balls at the same time, but some people can throw 5 balls and perform other tricks at the same time. However, the brain white matter of these subjects has changed, indicating that the effect comes from training, and has nothing to do with personal conditions.
