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.
关于该主题已知的信息有哪些？：身体活动（PA）和久坐行为（SB）是身心健康结果的关键决定因素。然而，在中国，尚未广泛开展使用这些行为的客观测量方法的大规模研究。
本报告补充了哪些内容？：根据世界卫生组织的指南，56.8%的参与者通过每周累积超过150分钟达到了中度至剧烈身体活动（MVPA）的建议。此外，37.3%的人遵守了每天少于8小时的久坐行为指南。然而，只有2.7%的成年人同时达到了MVPA和SB的建议。
对公共卫生实践有何启示？：本研究通过使用腰部佩戴式加速度计，对中国成年人的身体活动水平和久坐行为模式提供了新的见解。在这个多省份样本中观察到的身体活动不足和久坐行为过多的趋势强调了迫切需要有针对性的干预措施，以促进身体活动并减少久坐时间，从而培养更健康的生活方式行为。
