Abstract

Background

Rural residents are more impacted by obesity and related comorbidities than their urban counterparts. Digital weight management interventions may produce meaningful weight loss among rural residents.

Objectives

The iREACH Rural Study aims to identify “high-touch” component(s) that contribute to meaningful weight loss (≥1.5 kg) at 6-months, over and above what the 24-week core online program produces. Three treatment components are assessed: group video sessions (yes/no); self-monitoring feedback (counselor-crafted/pre-scripted, modular); and individual coaching calls (yes/no).

Design

The iREACH Rural Study is a factorial experiment (n = 616).

Methods

Participants receive up to 3 “high-touch” components (weekly synchronous facilitated group video sessions, weekly counselor-crafted self-monitoring feedback, and individual coaching calls) to determine which contribute meaningfully to 6-month weight loss. Participants complete assessments at baseline, 2 months, 6 months, and 12 months. Weight loss at 6 months (primary outcome) and 12 months (secondary outcome) is measured by Bluetooth-enabled scales. The study seeks to identify the weight loss approach for underserved rural residents which optimizes weight change outcomes and also examines costs associated with delivering different treatment constellations.

Summary

The iREACH Rural Study is the first of its kind to isolate digital weight loss intervention components to determine which meaningfully contribute to long-term weight loss among rural residing individuals. The results may be used to refine digital weight loss programs by enhancing their effectiveness to allow broad dissemination.

通过优化数字肥胖症治疗中的 "高接触 "干预内容，解决农村健康差距问题：iREACH 农村研究。

背景：与城市居民相比，农村居民受肥胖及相关并发症的影响更大。数字化体重管理干预措施可能会使农村居民的体重得到有效减轻：iREACH农村研究旨在确定 "高接触 "部分，这些部分有助于在6个月后实现有意义的体重减轻（≥1.5公斤），超过24周核心在线项目的效果。对三个治疗部分进行了评估：小组视频课程（是/否）；自我监测反馈（咨询师设计/预设，模块化）；个人辅导电话（是/否）：iREACH 农村研究是一项因子实验（n = 616）：方法：参与者最多可接受 3 个 "高接触 "部分（每周同步促进小组视频课程、每周咨询师自编自我监控反馈和个人辅导电话），以确定哪些部分对 6 个月的体重减轻有意义。参与者在基线、2 个月、6 个月和 12 个月时完成评估。6个月（主要结果）和12个月（次要结果）的体重减轻情况由蓝牙体重秤测量。摘要：iREACH 农村研究是同类研究中首次分离出数字减肥干预成分，以确定哪些成分对农村居民的长期减肥有意义。研究结果可用于完善数字减肥计划，提高其有效性，以便广泛推广。

期刊介绍： Contemporary Clinical Trials is an international peer reviewed journal that publishes manuscripts pertaining to all aspects of clinical trials, including, but not limited to, design, conduct, analysis, regulation and ethics. Manuscripts submitted should appeal to a readership drawn from disciplines including medicine, biostatistics, epidemiology, computer science, management science, behavioural science, pharmaceutical science, and bioethics. Full-length papers and short communications not exceeding 1,500 words, as well as systemic reviews of clinical trials and methodologies will be published. Perspectives/commentaries on current issues and the impact of clinical trials on the practice of medicine and health policy are also welcome.
