US scientists have conducted a study into the world fittest and least fittest countries.
Using data collected from smartphones, researchers from Stanford University analysed how many steps more than 700,000 people from around the world took each day in a bid to try and find out which factors determine obesity levels.
The average number of steps taken by people worldwide was found to be 4,96 per day.
Hong Kong found to be the ‘fittest’ finishing at the top of the list with people taking an average of 6,880 steps per day.
Indonesia was found to be the laziest, taking the least amount of steps with an average of just 3,513.
Thailand was ranked in 31st place out of 46, with an average of 4,764 steps, just one place behind the United States in 30th which averaged 4,774 steps.
Thailand ranked considerably better than some of its Asean neighbours, with the Philippines ranked 43rd with an average of 4,008 steps and in 44th place was Malaysia with 3,963 steps.
Australia, Canada, New Zealand and India also fell below the average.
The study was published in the Nature journal and used data collected from the Argus app, which lets users track their daily activity, heart rate, food intake and sleep.
Interestingly, the results of the study found that ‘activity inequality’ was the highest importance rather than the average number of steps when it comes to determining obesity levels.
Countries with just a small gap between most and least active had low levels of obesity, while countries such as the USA and Mexico have similar averages, Mexico has a higher level of activity inequality, and as a result has higher obesity levels.
Gender was also a key factor. Countries higher levels of activity inequality found that women are less active than men, while countries with low levels of obesity found that men and women had similar amounts of activity.
“The study is 1,000 times larger than any previous study on human movement”, professor Scott Delp told the BBC.
“There have been wonderful health surveys done, but our new study provides data from more countries, many more subjects, and tracks people’s activity on an ongoing basis.
“This opens the door to new ways of doing science at a much larger scale than we have been able to do before.”
