One in four adults globally, which comes to 28 percent or 1.4 billion people, are physically inactive, according to Lancet Global Health.
This can be as high as one in three adults inactive in some counties, the report – Worldwide trends in insufficient physical activity from 2001 to 2016- of Lancet said.
Women were less active than men, with an over 8 percent difference at the global level (32% men vs 23%, women). High income countries are more inactive (37%) compared with middle income (26%) and low income countries (16%).
The data has been reached &rom 358 surveys across 168 countries, including 1·9 million participants.
It said prevalence of insufficient physical activity varied greatly across regions and income groups in 2016. The highest levels were found in Latin America and the Caribbean, high-income Western countries, and high-income Asia Pacific, and prevalence was more than double in high-income countries than in low-income countries in 2016. In wealthier countries, the transition towards more sedentary occupations and personal motorised transportation probably explains the higher levels of inactivity. Conversely, in lower-income countries, more activity is undertaken at work and for transport; however, these behaviours are changing rapidly, the report said.
