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.
