Research on
physical activity and
health is actively being conducted. In the
Korea National Health and Nutrition Examination Survey (KNHANES), the Global
Physical Activity Questionnaire (GPAQ) was newly introduced in 2014. The purpose of this study was to investigate the levels of
physical activity and related factors in
Koreans who were assessed through the GPAQ by dividing the
physical activity by
occupation,
leisure, and transport domain. This study used data from the KNHANES (2014–2016), the study
population of which included 17,357 participants
aged 12 to 80 years. We compared the differences in
physical activity by
sociodemographic factors,
health-related factors, and psychological
health-related factors. Moreover, we also compared the mean
metabolic equivalent of task and daily
sitting time according to
physical activity domain by
sex and
age group. Finally, we investigated the
sociodemographic factors,
health-related factors, and psychological
health-related factors that significantly
affect the average
physical activity per week. The various factors were found to differ in the frequency of
physical activity levels. In addition, there was a difference in the amount of
physical activity per
occupation,
leisure, and transport domain in each
age group. Finally, age,
sex,
high-density lipoprotein cholesterol levels,
arthritis,
allergic rhinitis and
sinusitis, sleeping
time, and perceived
health status significantly affected
physical activity. The levels of
physical activity significantly differed by
sociodemographic factors,
health-related factors, and psychological
health-related factors. There was also a difference in the
physical activity levels according to the age and
sex per each domain of
physical activity.
