技术和在线社交网络(OSN)的增长可能会为医疗保健提供者提供一种创新的方式来提供体重管理计划，这可能会对人口层面的医疗保健产生影响。这项研究的目的是评估使用OSN提供减肥计划的可行性和有效性，以便为未来的大规模试验提供信息。70名肥胖(BMI=36.2±44.0)的肥胖者(年龄=0.47±0.12.4，少数民族=0.24.3)完成了为期6个月的减肥干预，并被随机分为电话会议或OSN交付组。体重减轻是通过将能量摄入比估计的每日总能量消耗减少500-700千卡·d−1，并将体力活动进行到每周300min来实现的。在整个干预过程中，每周都会提供行为减肥策略。电话会议和OSN组从基线到6个月的临床有意义的体重下降了5%(电话≥=−6.3%±66.4%，OSN−=5.8%±66.7%)。两组间体重变化无显著差异(p=0.765)。电话和OSN小组符合美国心脏协会/美国心脏病学院/肥胖协会的指导方针，在6个月内将基线体重减少了5%-10%。OSNs似乎是一个可行的减肥干预交付平台；然而，还需要进行更大规模、动力充足的试验。
The increase in technology and online social networks (OSNs) may present healthcare providers with an innovative modality for delivering weight management programmes that could have an impact on health care at the population level. The objective of this study was to evaluate the feasibility and efficacy of using an OSN to deliver a weight loss programme to inform future, large‐scale trials. Seventy individuals (age = 47 ± 12.4, minority = 24.3%) with obesity (BMI = 36.2 ± 4.0) completed a 6‐month weight loss intervention and were randomized to either a conference call or OSN delivery group. Weight loss was achieved by reducing energy intake by 500–700 kcal·d−1 below estimated total daily energy expenditure and progressing physical activity to 300 min/week. Behavioural weight loss strategies were delivered weekly throughout the intervention. Conference call and OSN groups produced clinically meaningful weight loss of ≥5% from baseline to 6 months (phone = −6.3 ± 6.4%, OSN = −5.8 ± 6.7%). There was no significant difference in weight change between groups (p = 0.765). The phone and OSN groups met the American Heart Association/American College of Cardiology/The Obesity Society's Guidelines by reducing baseline weight by 5–10% within 6 months. OSNs appear to be a viable delivery platform for weight loss interventions; however, larger scale adequately powered trials are needed.
