In clinical practice, it is difficult to convey the benefits of sustained physical activity to adult patients with excess weight or obesity. For this purpose, a goal-setting walking prescription may be an effective strategy.
This study aimed to determine the efficacy of the intervention of a pedometer app in setting a goal to reach 10,000 steps per day in adults.
Overweight adults (n=98; mean body mass index 32.53 [SD 4.92] kg/m2) were randomized to one of two conditions (control or intervention). Both groups downloaded a pedometer app that recorded their daily step counts and were given a daily walking goal of 10,000 steps. Subjects participated in a 24-week in-person behavioral weight control program and were asked to monitor their daily levels using the pedometer app. Baseline data were recorded and followed up weekly. Only the intervention group had structured information delivery, a personalized physical activity prescription, and follow-up on number of steps per day.
The results show that regardless of sex or age, prescribing walking increased the number of steps per day by 4806 step on average (standardized β coefficient=-0.813, SE=427.586, t=-11.242, P<.001).
These results could have implications for improving self-monitoring in overweight adults during periods of weight loss. Health professionals should analyze the implementation of tools that permit them to prescribe, follow up, and encourage the achievement of a goal of physical activity in overweight or obese patients.

在临床实践中，向超重或肥胖的成年患者传达持续身体活动的益处具有一定难度。为此，设定目标的步行处方可能是一种有效的策略。
本研究旨在确定计步器应用程序设定每天达到 10000 步目标的干预措施的效果。
将 98 名超重成年人（平均身体质量指数 32.53 [4.92] kg/m2）随机分为两组（对照组或干预组）。两组均下载了记录日常步数的计步器应用程序，并设定每天 10000 步的步行目标。受试者参加了 24 周的面对面行为体重控制计划，并被要求使用计步器应用程序监测日常水平。记录基线数据并每周进行随访。只有干预组才有结构化的信息传递、个性化的体育活动处方以及对每天步数的随访。
结果表明，无论性别或年龄如何，规定步行可使每天的步数平均增加 4806 步（标准化β系数=-0.813，SE=427.586，t=-11.242，P<.001）。
这些结果可能对改善超重成年人在减肥期间的自我监测具有重要意义。健康专业人员应分析实施工具的情况，这些工具可使他们为超重或肥胖患者规定、随访和鼓励实现身体活动目标。
