The problem of obesity, cardiovascular and other diseases, the cause of which a sedentary lifestyle and overeating is probably one of the main problems of our time . Previously, it was believed that the most obese citizens – in the UK and the US, although in fact, the leaders in the obesity of their inhabitants are Kuwait and Saudi Arabia. But in what countries do people lead the most active way of life? It is not so easy to learn, but it is possible. For several years scientists from Stanford decided to find out which citizens are moving the most.
In their work the specialists used the information accumulated by the cloud fitness application Azumio Argus. Among other functions, this program allows you to find out how active the lifestyle of its user. Experts analyzed a massive sample, which included information on 717.5 thousand people from 111 countries. The physical activity of all these people was monitored for 95 days. Azumio Argus users' data are anonymous, although scientists see such parameters as age, height, sex and weight of a person.
So, it turned out that people lead the most inactive way of life in Indonesia. Here, the application users pass approximately 3513 steps per day. They are followed by citizens of Saudi Arabia with their 3807 steps, Malaysia (3,963 steps), the Philippines (4008) and South Africa (4105).
List of countries whose residents are most active and go more steps than citizens of other states, Such:
1. Hong Kong – 6880 steps per day.
2. China – 6189.
3. Ukraine – 6107.
4. Japan – 6010.
5. Russia – 5969.
6. Spain – 5936.
7. Sweden – 5863.
8. South Korea – 5755.
9. Singapore – 5674.
10. Switzerland – 5512.
In addition, the scientists also tried to find out how different in each of the countries the ratio of active users to citizens who hardly move.
"If you imagine a part of people as" rich in physical activity "and other" poor ", then the gap between the first and second is an excellent indicator of the possible level of obesity in such a community" , – said one of the authors of the study, Scott Delp. Interestingly, the countries with the lowest level of inequality are Saudi Arabia (32.2), Australia (30.4) and Canada (30.3). Slightly lower levels of Hong Kong (index 22.2), China with the index 24.4 and Sweden (24.6), with South Korea (24.7) and the Czech Republic (24.8). Here, the lower the number, the lower the level of obesity in the country.
In addition, interesting results have also been obtained regarding "sexual inequality". That is, in some countries men are more active, in some – women. In most countries, men are still more physically active than women. The biggest gap between the levels of physical activity of men and women is in Qatar, Saudi Arabia and Malaysia. But the most insignificant difference is in Sweden, Ukraine and Russia.
An interesting point in the study is that the average number of steps in the country is weakly interrelated with the spread of the problem of obesity among the inhabitants of this country. But there is a direct link between "inequality" and the level of obesity, as indicated above. Another aspect of the study is the availability of conditions for pedestrians in different cities. If there are a lot of roads and cars in the village, the pedestrians are more difficult, respectively, and the level of activity of the city's residents (only cities were estimated) is lower. True, in some cities there are many roads and cars, but the infrastructure provides for walking. Among a number of cities in the US, San Francisco was recognized as one of the most convenient for pedestrians, which is the fourth in the United States in this indicator.
According to scientists, research of this type is easy to carry out due to the abundance of data. The fact is that the overwhelming majority of the population of cities, especially large ones, carry smartphones with them. The latter are often equipped with a variety of fitness applications that capture the number of steps passed, the total distance and other factors. This is made possible by the presence of gyroscopes, GPS, wireless communication modules and other elements of the phone's design. The data collected by the researchers were uploaded to Github.
Many smartphone users also own various "smart" devices, such as fitness trackers. They are used to more accurately monitor their own physical activity. Now most of the trackers are equipped, besides the usual elements, also with heart rate monitors. As a result, information about the physical load of a person is used not only by users themselves, but also by employers, insurance companies and other organizations.
