Physical activity (PA) and sedentary behaviours (SB-i.e. activities involving low-energy expenditure and a sitting/reclining posture) may each have significant implications for weight loss and other bariatric surgery outcomes. While early studies suggested that patients typically comply with clinical recommendations to adopt habitual PA, these data were based on retrospective questionnaires. Conversely, recent studies incorporating mobile health (mHealth) technologies (e.g. objective monitors), which assess PA and SB in real time and in the natural environment, show that most patients are inactive and highly sedentary pre-operatively and only make modest changes in these behaviours postoperatively. In addition to using mHealth technologies for obtaining accurate and detailed information on PA and SB, they are increasingly being employed to intervene on patients' PA and SB and/or evaluate intervention outcomes. Researchers and clinicians are encouraged to consider the benefits of using mHealth technology when studying and treating PA and SB in bariatric surgery patients.
身体活动（PA）和久坐行为（SB，即涉及低能量消耗以及坐姿/躺姿的活动）可能各自对减肥及其他减肥手术结果具有重大影响。早期研究表明患者通常会遵照临床建议养成习惯性身体活动，但这些数据是基于回顾性问卷调查得出的。相反，近期纳入移动健康（mHealth）技术（如客观监测器）的研究，这些技术可在自然环境中实时评估身体活动和久坐行为，结果显示大多数患者术前不活动且久坐时间很长，术后在这些行为方面仅有适度改变。除了使用移动健康技术获取有关身体活动和久坐行为的准确详细信息外，它们越来越多地被用于干预患者的身体活动和久坐行为及/或评估干预结果。在研究和治疗减肥手术患者的身体活动和久坐行为时，鼓励研究人员和临床医生考虑使用移动健康技术的益处。
