Advances in the device and smartphone technology have resulted in a convenient option for providing physical activity strategies; this is especially important during the coronavirus disease 2019 pandemic.
The purpose of this meta-analysis is to evaluate the efficacy of wearable and smartphone-based interventions to promote physical activity and improve quality of life and cardiovascular health outcomes among overweight/obese adults.
We searched relevant databases up to 18 November 2021 for conducting a systematic review and meta-analysis of randomized controlled trials lasting 4 or more weeks that investigated the impacts of wearables and smartphone applications on physical activity, quality of life and health outcomes.
Twenty-six studies including 2373 participants were included. There was a significant pooled standard mean differences (SMD) for the comparison between intervention versus control in steps per day (SMD: 0.54; 0.0003), moderate-to-vigorous physical activity (SMD: 0.47; 0.02), quality of life (SMD: 0.33; 0.0006), body weight (mean difference (MD), -1.61 kg; 0.009), and BMI (MD, -0.59 kg/m; 0.04). There were no significant differences between the intervention and control groups for systolic and diastolic blood pressure and resting heart rate (all 0.05).
Our findings suggest that wearable and smartphone-based interventions are effective strategies in promoting physical activity and can provide a direct contact line to health professionals.
设备和智能手机技术的进步为提供身体活动策略带来了便利选择；这在2019年冠状病毒病大流行期间尤为重要。
本荟萃分析的目的是评估基于可穿戴设备和智能手机的干预措施对促进超重/肥胖成年人身体活动、改善生活质量和心血管健康结果的疗效。
我们检索了截至2021年11月18日的相关数据库，以对持续4周或更长时间的随机对照试验进行系统评价和荟萃分析，这些试验调查了可穿戴设备和智能手机应用程序对身体活动、生活质量和健康结果的影响。
纳入了26项研究，共2373名参与者。干预组与对照组在每日步数（标准化均数差（SMD）：0.54；P = 0.0003）、中度至剧烈身体活动（SMD：0.47；P = 0.02）、生活质量（SMD：0.33；P = 0.0006）、体重（均数差（MD），-1.61 kg；P = 0.009）和体重指数（MD，-0.59 kg/m²；P = 0.04）方面存在显著的合并标准化均数差。干预组和对照组在收缩压、舒张压和静息心率方面无显著差异（P均>0.05）。
我们的研究结果表明，基于可穿戴设备和智能手机的干预措施是促进身体活动的有效策略，并且可以为健康专业人员提供直接联系渠道。
