Accelerometer-Based Physical Activity and Health-Related Quality of Life in Korean Adults: an observational study using the Korea National Health and Nutrition Examination Survey
ABSTRACT
Background:
Earlier studies primarily focused on the relationship between self-reported physical activity and health-related quality of life (HRQoL). There are few studies on objectively measured physical activity and quality of life (QoL), and none of them were conducted in Korea.
Objective:
The aim of our study is to analyze the relationship between physical activity measured with an accelerometer and HRQoL.
Methods:
Among those who participated in the sixth Korea National Health and Nutrition Examination Survey (KNHANES), multivariate logistic regression analysis was conducted on 1,298 people who agreed to wear accelerometer, excluding pregnant women, those currently undergoing cancer treatment, and those with osteoarthritis and rheumatoid arthritis. HRQoL was measured by the EuroQoL group's EQ-5D, and physical activity was measured with an accelerometer and self-report questionnaire.
Results:
Persons who performed moderate to vigorous physical activity with an accelerometer for at least 10 minutes (MVPA-AB) ≥600 METs were associated with a significantly higher odds ratio of EQ-5D than those who performed MVPA-AB <600 METs (odds ratio [95% confidence interval]: 1.45 [1.01-2.09]). However, moderate to vigorous physical activity with an accelerometer for at least 1 minute (MVPA-AT) and self-reported physical activity was not significantly associated with EQ-5D.
Conclusions:
HRQoL was significantly higher in the group with more physical activity for at least 10 minutes, which was confirmed by an accelerometer in Korean adults.
