有规律的体力活动对改善和保持健康很重要，但久坐的行为很难改变。使用可穿戴式运动感应技术(活动监测器)提供客观、实时的体力活动反馈，可能是增加体力活动或减轻体重的一种有前景的、可扩展的策略。我们综合了有关使用可穿戴活动监测器来改善体力活动和体重相关结果的文献，并评估了可能对有效性产生影响的缓和因素。我们搜索了从2000年1月到2015年1月的五个数据库，以寻找成人中的同行评议的英语随机对照试验。随机效应模型用于产生体力活动结果的标准化平均差(SMDS)和体重结果的平均差(MD)。异质性用I2进行测量。14项试验(总共2972名参与者)符合资格标准；所有试验都使用了加速计。12项试验检查了加速计干预增加体力活动的情况。增加体力活动有轻微的显著影响(SMD为0.26；95%CI为0.04至0.49；I2=64.7%)。干预时间是唯一能显著解释体力活动高度异质性的调节因素。11项试验检测了加速度计干预对体重的影响。综合估计显示，体重减轻的效果很小(MD−1.65公斤；95%CI−3.03至−0.28；I2=81%)，没有主持人显著。加速计显示对体力活动和减肥有很小的积极作用。目前研究中的小样本量和中等到高度的异质性限制了可能得出的结论。未来的研究应该集中在如何最好地将加速度计与其他策略相结合，以增加体力活动和减肥。
Regular physical activity is important for improving and maintaining health, but sedentary behavior is difficult to change. Providing objective, real-time feedback on physical activity with wearable motion-sensing technologies (activity monitors) may be a promising, scalable strategy to increase physical activity or decrease weight. We synthesized the literature on the use of wearable activity monitors for improving physical activity and weight-related outcomes and evaluated moderating factors that may have an impact on effectiveness. We searched five databases from January 2000 to January 2015 for peer-reviewed, English-language randomized controlled trials among adults. Random-effects models were used to produce standardized mean differences (SMDs) for physical activity outcomes and mean differences (MDs) for weight outcomes. Heterogeneity was measured with I2. Fourteen trials (2,972 total participants) met eligibility criteria; accelerometers were used in all trials. Twelve trials examined accelerometer interventions for increasing physical activity. A small significant effect was found for increasing physical activity (SMD 0.26; 95% CI 0.04 to 0.49; I2=64.7%). Intervention duration was the only moderator found to significantly explain high heterogeneity for physical activity. Eleven trials examined effects of accelerometer interventions on weight. Pooled estimates showed a small significant effect for weight loss (MD −1.65 kg; 95% CI −3.03 to −0.28; I2=81%), and no moderators were significant. Accelerometers demonstrated small positive effects on physical activity and weight loss. The small sample sizes with moderate to high heterogeneity in the current studies limit the conclusions that may be drawn. Future studies should focus on how best to integrate accelerometers with other strategies to increase physical activity and weight loss.
