Abstract
This study aimed to determine the adequate physical activity level of Thai adults, and disaggregated
by subgroups of participants. The study re-analyzed data of 108,416 Thai adults aged 18 and
above from the 2015 National Health and Welfare Survey conducted by National Statistical Office. Descriptive
and analytical statistics were defined in the analysis. The results showed that 42.4% of Thai
adults aged 18 and above met physical activity level according to the recommendation by the World
Health Organization and 33.8% had high level of physical inactivity. Most males, farmers and laborers,
and those who had no underlying diseases, reached recommended physical activity level and had
low-rate of high level of physical inactivity. On the other hand, most elderly, unemployed, and those
who had underlying diseases, did not reach recommended physical activity level and had high-rate of
high level of physical inactivity. Our findings will benefit to the national policy development to reduce
sedentary behaviors and increase physical activity especially in work and transportation domains, with
the focus on the subpopulations that did not reach the recommended physical activity level and had
high level of physical inactivity.
