Weight loss interventions have been successfully delivered via several modalities, but recent research has focused on more disseminable and sustainable means such as telephone- or Internet-based platforms.
The aim of this study was to compare an Internet-delivered weight loss intervention to a comparable telephone-delivered weight loss intervention.
This randomized pilot study examined the effects of 6-month telephone- and Internet-delivered social cognitive theory-based weight loss interventions among 37 cancer survivors. Measures of body composition, physical activity, diet, and physical performance were the outcomes of interest.
Participants in the telephone intervention (n=13) showed greater decreases in waist circumference (-0.75 cm for telephone vs -0.09 cm for Internet, P=.03) than the Internet condition (n=24), and several other outcomes trended in the same direction. Measures of engagement (eg, number of telephone sessions completed and number of log-ins) suggest differences between groups which may account for the difference in outcomes.
Cancer survivors in the telephone group evidenced better health outcomes than the Internet group. Group differences may be due to higher engagement in the telephone group. Incorporating a telephone-based component into existing weight loss programs for cancer survivors may help enhance the reach of the intervention while minimizing costs. More research is needed on how to combine Internet and telephone weight loss intervention components so as to maximize engagement and outcomes.

减肥干预措施已通过多种方式成功实施，但最近的研究集中在更易于传播和可持续的方式上，如基于电话或互联网的平台。
本研究旨在比较基于互联网的减肥干预措施与类似的基于电话的减肥干预措施。
这项随机试点研究在37名癌症幸存者中检验了基于电话和互联网的、为期6个月的社会认知理论减肥干预措施的效果。身体成分、身体活动、饮食和身体机能的测量是感兴趣的结果。
电话干预组（n = 13）的参与者腰围下降幅度（电话组为-0.75厘米，互联网组为-0.09厘米，P = 0.03）大于互联网组（n = 24），其他几个结果也呈相同趋势。参与度测量（如完成的电话会议次数和登录次数）表明两组之间存在差异，这可能是结果差异的原因。
电话组的癌症幸存者比互联网组有更好的健康结果。组间差异可能是由于电话组的参与度更高。将基于电话的部分纳入现有的癌症幸存者减肥计划可能有助于扩大干预措施的覆盖范围，同时将成本降至最低。关于如何结合互联网和电话减肥干预措施以最大限度地提高参与度和结果，还需要更多研究。
