Obesity is a global epidemic with major healthcare implications and costs. Mobile technologies are potential interventions to promote weight loss. An early systematic review of this rapidly growing area of research was conducted. Electronic databases were searched for articles published between January 1998 and October 2011. Data sources included Medline, Embase and the Cochrane Central Register of Controlled Trials. Ongoing research was searched for using clinical trials databases and registers. Out of 174 articles retrieved, 21 met the inclusion criteria of randomized controlled trials (RCTs) on mobile technology interventions facilitating weight loss in overweight and obese adults with any other comparator. A narrative synthesis was undertaken. Seven articles were included and appraised using the Cochrane risk of bias tool: four presented a low risk of bias and three presented a high risk of bias. There is consistent strong evidence across the included multiple high-quality RCTs that weight loss occurs in the short-term because of mobile technology interventions, with moderate evidence for the medium-term. Recommendations for improving the reporting and quality of future trials are made including reporting weight loss in percent to meet clinical standards, and including features such as long-term follow-up, cost-effectiveness and patient acceptability.
肥胖是一种全球性的流行疾病，对医疗保健有重大影响并带来巨大成本。移动技术可能是促进减肥的干预手段。本研究对这一日益增长的研究领域进行了早期的系统综述。电子数据库检索了 1998 年 1 月至 2011 年 10 月期间发表的文章。数据来源包括 Medline、Embase 和 Cochrane 对照试验中心注册库。还使用临床试验数据库和注册库搜索正在进行的研究。在检索到的 174 篇文章中，有 21 篇符合纳入标准，即随机对照试验（RCT），研究对象为超重和肥胖成年人，比较了移动技术干预措施促进减肥的效果。采用叙述性综合法进行分析。有 7 篇文章被纳入并使用 Cochrane 偏倚风险工具进行评估：4 篇文章的偏倚风险较低，3 篇文章的偏倚风险较高。纳入的多项高质量 RCT 都一致提供了有力的短期移动技术干预可导致体重减轻的证据，而中期证据则适度。为提高未来试验的报告和质量提出了相关建议，包括按照临床标准报告体重减轻的百分比，并纳入长期随访、成本效益和患者可接受性等特点。
