Full exercise prevents at least 3.9 million premature deaths each year

"East" has HuaYu "movement to disease", "West" has Hippocrates "movement is the best doctor of mankind". But in reality, there are always a lot of people for a variety of reasons "away" from the movement.
more than a third of the world's adults (about 1.4 billion people) were insanity in 2016, according to the World Health Organization. According to the "Healthy China 2020" strategic research report, china's 18-year-old residents in the proportion of people who never exercise as high as 83.8%.
studies have shown that lack of exercise is associated with an increased risk of death. "Inadequate exercise is currently the fourth high risk factor for death in the world, with a 20 to 30 per cent increased risk of death compared to those who exercise adequately," the WHO said in a 2017 media release.
recently, the Team Tessa Strain, Ph.D., University of Cambridge, changed its perspective, finding that globally, adequate exercise prevents premature death in at least 3.9 million adults between the ages of 40 and 74 each year. The study was published in The Lancet Global Health.。 "Many studies have suggested that unhealthy lifestyles can cause disease and the burden of death, but there are few positive studies around healthy lifestyles that avoid the burden of disease and death," strain said. This is the first positive study to assess the impact of exercise on the prevention of premature deaths globally. The
team collected data on physical activity prevalence and all-cause mortality in 168 countries worldwide released by the WHO in 2016 between 2001 and 2016. To avoid the effects of neonatal complications and death from old age, the researchers limited the age of the subjects to 40 to 74 years old. They believe this is the age range most likely to cause premature death due to lack of exercise.
researchers used the WHO's recommendation of "at least 150 minutes of moderate-intensity aerobic exercise per week, or 75 minutes of high-intensity exercise, or the same intensity of exercise combination" as the criteria for studying "exercise."
to understand the relationship between exercise and reducing the risk of premature death, the researchers used the concept of Population Prevention Scores (FP). Because PPF can reflect the proportion of deaths prevented by exercise in the subject population.
, sports prevented 15 percent of premature deaths globally, and men's sports prevention scores (16 percent) were higher than women's (14.1 percent), according to the study. In other words, the campaign prevents at least 3.9 million premature deaths each year, benefiting 1.5 million women and 2.5 million men.
team also found that exercise prevention scores were different in different income levels. Sport prevention scores were highest in Africa at 16.6 per cent and lowest in the Americas at 13.1 per cent. "Sports prevention scores in low-income countries (17.9 per cent) are higher than in high-income countries (14.1 per cent). In China, exercise prevents 18.3% of premature deaths. In other words, 1.0165 million people between the ages of 40 and 74 die prematurely each year as a result of exercise.good for sports, but how should I exercise?
In 2018, the second edition of the exercise guidelines, released by the U.S. Department of Health and Human Services, emphasize that adults do at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of high-intensity aerobic exercise per week, or a combination of both;
recently, researchers such as Xi Bo, a professor at Shandong University's School of Public Health, based on the guidelines, explored the relationship between meeting the recommended amount of the guidelines for two forms of exercise (aerobic and fitness) and reducing the risk of death in the population. The findings were published in the British Medical Journal.
most studies have focused on the relationship between aerobic exercise and population health, and some studies have focused on the relationship between physical activity and population health," Xibo told China Science Daily. But at the same time, there were only four studies looking at the relationship between aerobic and fitness forms and population health, and the conclusions of the four studies were not consistent. To
, the team collected and analyzed data on about 480,000 adults over the age of 18 from 1997 to 2014 in the U.S. National Health Visit Survey. The study found that only 16 percent of the population met the amount of aerobic and fitness exercise recommended by the guidelines, only 24 percent of the aerobic exercise recommended by the guidelines, and only 4.5 percent of the exercise recommended by the guidelines.
To get more accurate results, the team adjusted factors such as age, gender, smoking, alcohol consumption and high blood pressure to find that meeting only the recommended amount of exercise in the guidelines reduced premature deaths by 11 percent compared to people who were not exercised, that meeting only the amount of aerobic exercise recommended by the guidelines reduced premature deaths by 29 percent, and that meeting the amount of aerobic and fitness exercise recommended by the guidelines reduced premature deaths by 40 percent.
team also found that as we grew older, the proportion of exercise subjects who met the guidelines decreased, mostly young, male, unmarried, non-smoking, with a healthy body mass index and a lower risk of chronic diseases." meeting the recommended amount of exercise in the guidelines not only reduces the risk of all-cause death, but also reduces the risk of death from cardiovascular disease, influenza and pneumonia, chronic lower respiratory tract infections, nephropathy, Alzheimer's disease, diabetes, tumors, and other diseases. "The Sibo team found that aerobics and fitness training met the recommended standards of the guidelines and had a more significant impact on the reduced risk of death from a particular disease.
But for kidney diseases such as nephritis and nephropathy syndrome, the risk of death was slightly higher (52%) than in the other two groups (only 29%) and aerobics and fitness training (48%).
" this study, based on international cooperation, using 480,000 people in the U.S. National Health Database, using a queue study design, follow-up time is long, the results of extraterrive, strong ability to test causation. Sibo said.
, "insufficient time, insufficient health awareness, chronic diseases, etc. are the main reasons for people's lack of exercise at present."
China's Disease Burden Study 2005-2017, the level of national exercise participation is still at a low level, and the impact of sit-in lifestyle is expanding. According to the 2007-2013 survey data, China's adult sitting time is on the rise, most of the sitting time is in front of mobile phones, computers and other electronic screens.
In order to improve the current situation of people's lack of exercise, Xibo said: "The government should increase fitness facilities, such as in the community to increase fitness equipment, increase running channels in the park, etc. ;
" exercise is good for your health even if it doesn't meet the guidelines. Sibo said. (Source: Tian Ruiying, China Science Journal)
