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病有关，包括2型糖尿病。 (T2 DM)。减肥已被证明有助于预防2型糖尿病。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。社交 支持还有助于鼓励持续的饮食自我监测，这被认为是 减肥治疗和针对T2 DM预防和治疗的干预措施的重要组成部分 管理层。很少有研究专门针对已经证实的社会支持领域的方法 要在面对面的交付环境中有效。 社交减重(Social POD)研究是一项为期三个月的随机减肥研究 干预，通过每周两次的播客远程提供内容(两个干预部门相同)。 超重成年人(N=51)被招募并随机分配到试验组(n=26； 获得自我监控和社会支持积分的社交POD APP)或对照组(n=25)； 没有积分的标准饮食跟踪应用程序)。社交POD小组参与者减掉的体重明显更多(-5.3 Kg；95%CI：-7.5，-3.0)高于标准APP组(-2.2 kg；95%CI：-3.6，-1.0；p=0.02)和总分 获得显著预测体重下降百分比(B=-0.02，p=0.01)。这项研究，39%的参与者是 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。这个 本提案的目标是在一项较长期的研究(12个月)中审查社会POD干预 确保社交游戏的使用带来可持续的行为改变和持续的减肥。 我们的研究有以下目的：目的1)确定社交POD应用程序加积分干预 (Social POD+积分；提供和接受社会支持的积分)能显著增加减肥效果 在240名超重或肥胖的成年人中，12个月时比社会无积分POD(Social POD-) 和≥-3、T2 DM危险因素。假设：SocialPOD+Points组的体重将比 SocialPOD-组。目的2)审查不同群体之间在提供和接受社会支助方面的差异 12个月。假设：Social POD+Points组将有更多的社会支持提供 和收据超过了Social POD-。次要目标)检查随时间推移的使用模式[例如，点数是否持续 参与和促进减肥维持？]，潜在的调解人和主持人[参与(例如， 自我监测的频率)]、人口因素(例如，性别、种族、年龄)] 干预措施，以及社会支持提供/接受与心理社会因素(例如，动机、 享受)减肥。这种方法具有相当大的公共卫生吸引力，因为如果社交游戏 该方法被证明在促进和保持减肥方面是成功的，它可以大大扩大到 广泛传播。
