PROJECT ABSTRACT Weight gain is disproportionately high among young adults (YAs) with average weight gain of 30 lbs. occurring between ages 18-35 and is associated with an early worsening of CVD risk factors. Primary prevention of weight gain is important because weight loss is difficult to achieve, access to programs is limited, and initially successful people regain weight over time. Weight gain is a serious problem in the Department of Defense, our nation’s largest employer, with more employees than Walmart or Amazon. The military, comprised largely of YAs, has growing rates of obesity and yearly weight gain. Many people believe that young, active-duty men and women are fit, lean, and healthy because of the military lifestyle and protected from obesity. Unfortunately, obesity rates in active U.S. military personnel have mirrored those of civilians. Furthermore, inability to maintain a healthy weight results in early discharges and threatens the readiness of well-trained Airmen to be deployed. Overweight in the military is now considered a threat to national security. Few weight gain prevention (WGP) trials have been done in military populations, and previous trials with YAs have mixed results and poor external validity. Our proposal is designed to address the major public health problem of weight gain in the military, as well as address notable gaps in pragmatic mHealth and WGP trials. The SNAP- M intervention will be adapted, with partners and key stakeholder from the US Air Force, from our evidence- based WGP intervention for YAs, the Study of Novel Approaches to weight gain Prevention (SNAP). SNAP tested 2 self-regulatory interventions in 599 general population YAs and found that both reduced weight gain over 2-3 years compared to controls. This project proposes to make 1) critical adaptions to SNAP to facilitate translation and 2) conduct a Pragmatic Hybrid Type 1 Effectiveness Trial of the SNAP-M intervention using a 2-group randomized controlled trial (RCT) design in 454 Air Force Airmen recruited from 4 military installations with the primary outcome of mean weight change from baseline to 2 years. We will compare the groups on key outcomes and examine potential moderators of treatment effect. Additionally, we will apply a RE-AIM Framework to determine reach and representativeness, and potential for organizational-level adoption, implementation, and maintenance of SNAP-M, if successful. The proposed research fills key research gaps in an underserved population in critical need of weight gain prevention with completely remote delivery suitable for YAs in the military.

项目摘要 年轻人 (YAs) 的体重增加不成比例地高，平均体重增加 30 磅。 18-35 岁之间，与 CVD 危险因素的早期恶化有关。 体重增加很重要，因为减肥很难实现，参与计划的机会有限，而且最初 成功人士的体重随着时间的推移而增加，体重增加是我们国防部的一个严重问题。 美国最大的雇主，员工数量超过沃尔玛或亚马逊，其中大部分由军队组成。 许多人认为，年轻的现役男性的肥胖率和每年的体重增加都在增加。 不幸的是，由于军事生活方式，女性身体健康、苗条、健康，并且可以避免肥胖。 美国现役军人的肥胖率与平民的肥胖率相似。 保持健康的体重会导致提早退役，并威胁到训练有素的飞行员的准备能力 军队中的超重现在被认为是对国家安全的威胁。 预防 (WGP) 试验已在军队人群中进行，之前针对 YA 的试验结果好坏参半 我们的建议旨在解决主要的公共卫生问题。 军队的体重增加，以及解决实用的 mHealth 和 WGP 试验中的显着差距。 M 干预措施将与美国空军的合作伙伴和主要利益相关者一起根据我们的证据进行调整—— 基于 WGP 的 YAs 干预措施，即预防体重增加新方法研究 (SNAP)。 在 599 名普通人群中测试了 2 种自我调节干预措施，发现这两种干预措施都减少了体重增加 与对照相比，需要 2-3 年时间。这建议项目对 SNAP 进行 1) 关键调整以促进实施。 翻译和 2) 使用 SNAP-M 干预措施进行务实混合 1 型有效性试验 对从 4 个军事设施招募的 454 名空军飞行员进行的 2 组随机对照试验 (RCT) 设计 主要结果是从基线到两年的平均体重变化，我们将比较各组的关键点。 此外，我们将应用 RE-AIM。 确定覆盖范围和代表性以及组织层面采用潜力的框架， 如果成功的话，SNAP-M 的实施和维护将填补关键研究空白。 服务不足的人群迫切需要通过完全远程交付来预防体重增加 对于军队中的青年学生。
