Summary
This summary is machine-generated.

Most Korean adults are sedentary and do not meet physical activity (PA) guidelines. Public health initiatives are needed to promote PA and reduce sedentary behavior (SB) for better health outcomes.

Area of Science:

  • Public Health
  • Epidemiology
  • Behavioral Science

Background:

  • Accelerometer-derived physical activity (PA) and sedentary behavior (SB) patterns are crucial for understanding adult health.
  • Limited data exists on these patterns and guideline adherence among Korean adults.

Purpose of the Study:

  • To present an overview of PA and SB patterns in Korean adults using accelerometers.
  • To examine associations between participant characteristics and adherence to moderate-to-vigorous physical activity (MVPA), SB, and combined MVPA-SB guidelines.

Main Methods:

  • Utilized data from the 2014-2017 Korea National Health and Nutrition Examination Survey.
  • Included a nationally representative sample of 2,260 Korean adults (≥20 years).
  • Employed accelerometers for 7-day PA and SB measurement and multivariate logistic regression for adherence analysis.

Main Results:

  • Sedentary behavior (60.61%) and light-intensity activity (26.22%) dominated participants' days; MVPA (3.72%) and vigorous PA (0.06%) were low.
  • Adherence to MVPA guidelines was higher among men, older adults, highly educated, non-smokers, and those without multimorbidity.
  • Higher education and income were linked to lower SB guideline adherence, while women, highly educated, smokers, and those with multimorbidity were less likely to meet MVPA-SB guidelines.

Conclusions:

  • Korean adults exhibit predominantly sedentary lifestyles with minimal vigorous PA.
  • Significant demographic and health disparities exist in PA and SB guideline adherence.
  • Low adherence to MVPA-SB guidelines presents a public health concern, necessitating targeted interventions and policies to promote PA and reduce SB.
