Overweight and obesity are linked to a number of chronic diseases, including type 2 diabetes mellitus (T2DM). Weight loss has been shown to help with the prevention of T2DM. Behavioral weight loss programs that provide, encourage, or facilitate social support are associated with greater adherence to treatment. Social support can also help to encourage consistent dietary self-monitoring, which is considered the cornerstone of weight loss treatment and an important component of interventions targeting T2DM prevention and management. Few studies have focused specifically on ways to target areas of social support that have proven to be effective in face-to-face delivery settings. The Social Pounds Off Digitally (Social POD) study was a three-month randomized weight loss intervention with content delivered remotely via twice-weekly podcasts (same for both intervention arms). Overweight adults (N=51) were recruited and randomly assigned to either the experimental group (n= 26; Social POD app that received points for self-monitoring and social support)) or the comparison group (n=25; standard diet tracking app with no points). Social POD group participants lost significantly more weight (-5.3 kg; 95%CI: -7.5, -3.0) than those in the standard app group (-2.2 kg; 95%CI: -3.6, -1.0; p=0.02) and total points earned significantly predicted % weight loss (B=-0.02, p=0.01). This study, with 39% of the participants being African American, represents one of the more diverse study samples for a digital weight loss intervention. The goal of the present proposal is to examine the Social POD intervention in a longer-term study (12 months) to ensure that use of social gaming leads to sustainable behavior changes and continued weight loss. Our study has the following aims: Aim 1) Determine if the Social POD app plus points intervention (SocialPOD+points; points for provision and receipt of social support) produces significantly more weight loss at 12 months than the Social POD without points (SocialPOD-) among 240 adults with overweight or obesity and ≥3 T2DM risk factors. Hypothesis: The SocialPOD+points group will lose more weight than the SocialPOD- group. Aim 2) Examine the differences in social support provision and receipt between groups at 12 months. Hypothesis: That the SocialPOD+points group will have greater levels of social support provision and receipt than the SocialPOD-. Secondary Aims) Examine usage patterns over time [e.g., do points sustain engagement and promote weight loss maintenance?], potential mediators and moderators [engagement (e.g., frequency of self-monitoring)], demographic factors (e.g., sex, race, age)], the usability and acceptability of the interventions, and the association of social support provision/receipt and psychosocial factors (e.g., motivation, enjoyment) with weight loss. This approach has considerable public health appeal since, if the social gaming approach proves to be successful in promoting and maintaining weight loss, it could be greatly scaled up for widespread dissemination.

超重和肥胖与许多慢性疾病有关，包括 2 型糖尿病 （T2DM）。减肥已被证明有助于预防 T2DM。行为减肥计划 提供、鼓励或促进社会支持与更好地坚持治疗有关。社会的 支持还可以帮助鼓励持续的饮食自我监测，这被认为是 减肥治疗和针对 T2DM 预防和干预的重要组成部分 管理。很少有研究专门关注已证明社会支持目标领域的方法 在面对面的交付环境中有效。 Social Pounds Off Digitally (Social POD) 研究是一项为期三个月的随机减肥研究 通过每周两次的播客远程提供内容进行干预（两个干预组相同）。 招募超重成年人 (N = 51) 并随机分配到实验组 (n = 26; 因自我监控和社交支持而获得积分的社交 POD 应用程序）或对照组（n=25； 标准饮食跟踪应用程序，没有积分）。社交 POD 组参与者的体重明显减轻（-5.3 公斤； 95%CI: -7.5, -3.0) 高于标准应用组 (-2.2 kg; 95%CI: -3.6, -1.0; p=0.02) 和总分 获得了显着预测的体重减轻百分比（B=-0.02，p=0.01）。这项研究中，39% 的参与者 非裔美国人代表了数字减肥干预的更多样化的研究样本之一。这 本提案的目标是在一项长期研究（12 个月）中检验 Social POD 干预，以 确保社交游戏的使用带来可持续的行为改变和持续减肥。 我们的研究有以下目标： 目标 1) 确定 Social POD 应用程序是否加积分干预 （SocialPOD+积分；用于提供和接受社会支持的积分）可显着减轻体重 12 个月时，与 240 名超重或肥胖成年人的无积分社会 POD (SocialPOD-) 相比 ≥3 个 T2DM 危险因素。假设：SocialPOD+积分组将比 SocialPOD-组。目标 2) 检查不同群体之间社会支持提供和接受的差异 12个月。假设：SocialPOD+积分组将获得更高水平的社会支持 和收据比SocialPOD-。次要目标）检查一段时间内的使用模式[例如，积分是否维持 参与并促进减肥维持？]，潜在的调解者和调节者[参与（例如， 自我监控的频率）]、人口因素（例如性别、种族、年龄）]、该工具的可用性和可接受性 干预措施，以及社会支持提供/接受与社会心理因素（例如动机、 享受）与减肥。这种方法具有相当大的公共健康吸引力，因为如果社交游戏 事实证明，这种方法在促进和维持减肥方面是成功的，可以大大扩大规模 广泛传播。
