Abstract

BACKGROUND

Even in the absence of weight loss, any level of physical activity (PA) can reduce the risk of cardiovascular disease among individuals with obesity. However, these individuals face multifaceted barriers that reduce their motivation and engagement in PA. They prefer programs that are convenient, fun to engage in, and feature people who they can relate to. Yet, there is a paucity of PA interventions that are designed to incorporate these preferences. We designed the web-based PA for The Heart (PATH) intervention to address this gap.

OBJECTIVE

This study aimed to describe the protocol of a study that aims to examine the acceptability and preliminary efficacy of PATH intervention among insufficiently active adults with obesity aged at least 18 years.

METHODS

This is a 6-month pilot randomized controlled trial (RCT), using a parallel design with 1:1 allocation to intervention or control group. The PATH intervention group is given access to the PATH platform, but the resources each participant can access are tailored according to their baseline fitness level. Control group receives a self-help PA handout. Both groups self-monitor their PA using Fitbit (Google) and have Zoom (Zoom Video Communications) meetings twice a month with either the health coach (intervention) or study coordinator (control). The outcomes at 6-months include acceptability, changes in PA, and cardiometabolic risk from baseline to 6-months.

RESULTS

We screened 763 individuals for eligibility and 89 participants were enrolled and randomized to the intervention (45/504, 50.6%) and control arms (44/504, 49.4%). The average age was 48.7 (SD 12.17) years, and most participants were female (81/504, 90.1%), Black (45/504, 50.6%), and non-Hispanic (83/504, 93.3%). No systematic differences in baseline characteristics were observed between the study arms. The 6-month intervention is currently underway, and the completion of follow-up data collection is expected in February 2025, with results to be published soon after.

CONCLUSIONS

The PATH intervention offers a promising, evidence-based approach to overcoming the barriers that have hindered previous PA programs for adults with obesity. It can support new and existing programs to foster long-term maintenance of health-enhancing PA.

摘要

背景

即使在没有体重减轻的情况下，任何水平的身体活动（PA）都可以降低肥胖个体患心血管疾病的风险。然而，这些个体面临多方面的障碍，这些障碍降低了他们参与身体活动的动力和积极性。他们更喜欢方便、有趣且有与自己有共鸣的人的项目。然而，旨在纳入这些偏好的身体活动干预措施却很少。我们设计了基于网络的心脏身体活动（PATH）干预措施来填补这一空白。

目的

本研究旨在描述一项研究的方案，该研究旨在检验PATH干预措施在年龄至少18岁、身体活动不足的肥胖成年人中的可接受性和初步疗效。

方法

这是一项为期6个月的试点随机对照试验（RCT），采用平行设计，按1:1分配到干预组或对照组。PATH干预组可以访问PATH平台，但每个参与者能够访问的资源会根据他们的基线健康水平进行调整。对照组收到一份自助身体活动手册。两组都使用Fitbit（谷歌）自我监测身体活动情况，并每月与健康教练（干预组）或研究协调员（对照组）进行两次Zoom（Zoom视频通讯）会议。6个月时的结果包括可接受性、身体活动的变化以及从基线到6个月时的心血管代谢风险。

结果

我们筛选了763名个体的资格，89名参与者被招募并随机分配到干预组（45/504，50.6%）和对照组（44/504，49.4%）。平均年龄为48.7（标准差12.17）岁，大多数参与者为女性（81/504，90.1%）、黑人（45/504，50.6%）和非西班牙裔（83/504，93.3%）。研究组之间在基线特征方面未观察到系统性差异。为期6个月的干预目前正在进行，预计2025年2月完成随访数据收集，结果将在之后不久公布。
