These people reported their activity at home, work, during travel and leisure time.
It was deduced that mostly in high-income countries like the United Kingdom and US, the percentage of inactive people has increased from 32 to 37 from 2001 to 2016.
Shockingly, nearly 40 percent of Irish women didn't get enough physical activity in 2016.
The study which provides the most comprehensive global estimates of the prevalence and trends of physical activity to date, included 358 surveys from 168 countries totalling 1·9 million people. Their findings were published Tuesday in The Lancet Global Health journal. "Latin America and the Caribbean, and high-income Western countries are the two regions with the highest levels of inactivity, and with increasing trends in inactivity". This is largely influenced by China, the authors stated, with leisure-time activity rising in the most populated country in the region, possibly through increased physical activity and use of public parks among its growing elderly population.
The prevalence was 20 percent to 29.9 percent among men in Bangladesh while 30 percent to 39.9 percent in women.
To encourage more people to exercise, World Health Organization launched a Let's Be Active campaign with a goal of reducing physical inactivity 10 percent by 2025 and 15 percent by 2030.
For additional health benefits, adults should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate- and vigorous-intensity activity.
-Insufficient physical activity is a leading risk factor for non-communicable diseases, and has a negative effect on mental health and quality of life. Among their results, they found a large disparity between the amount of inactivity among high-income countries (37 percent) compared to low-income countries (16 percent).
"As countries urbanise, people who used to be, say, farmers, and got a lot of physical activity through their work all of a sudden live in an urban environment where they might be without work or move to a sedentary job, so societies need to compensate", she said.
The Ministry of Health welcomes World Health Organization (WHO) findings about worldwide physical activity trends, which reinforces key messages about the benefits of being regularly physically active.
This growing inactivity is of "grave concern", the American Heart Association said in a statement.
Guthold said that countries and communities alike can address descending levels of exercise by "creating new opportunities and programs to support and engage people to be more active".
