Accelerometry-Based Physical Activity and Sedentary Behavior Among Chinese Adults - 7 PLADs, China, 2023.

What is already known on this topic?: Physical activity (PA) and sedentary behavior (SB) are crucial determinants of both physical and mental health outcomes. However, large-scale studies using objective measurements of these behaviors have not been widely implemented across China.

What is added by this report?: Based on World Health Organization guidelines, 56.8% of participants met the recommendation for moderate-to-vigorous physical activity (MVPA) by accumulating more than 150 minutes per week. Additionally, 37.3% adhered to the SB guideline of less than 8 hours per day. However, only 2.7% of adults achieved compliance with both MVPA and SB recommendations simultaneously.

What are the implications for public health practice?: This study provides novel insights into PA levels and SB patterns among Chinese adults using waist-mounted accelerometry. The observed trends of insufficient PA and excessive SB in this multi-provincial sample emphasize the urgent need for targeted interventions to promote physical activity and reduce sedentary time to foster healthier lifestyle behaviors.
