Purpose

The purpose of this study was to examine how maintenance session attendance and 6-month weight loss (WL) goal achievement impacted 12-month 5% WL success in older adults participating in a community-based Diabetes Prevention Program (DPP) lifestyle intervention.

Methods

Data were combined from 2 community trials that delivered the 12-month DPP-based Group Lifestyle Balance (GLB) to overweight/obese adults (mean age = 62 years, 76% women) with prediabetes and/or metabolic syndrome. Included participants (n = 238) attended ≥4 core sessions (months 0-6) and had complete data on maintenance attendance (≥4 of 6 sessions during months 7-12) and 6- and 12-month WL (5% WL goal, yes/no). Multivariate logistic regression was used to estimate the odds of 12-month 5% WL associated with maintenance attendance and 6-month WL. Associations between age (Medicare-eligible ≥65 vs <65 years) and WL and attendance were examined.

Results

Both attending ≥4 maintenance sessions and meeting the 6-month 5% WL goal increased the odds of meeting the 12-month 5% WL goal. For those not meeting the 6-month WL goal, maintenance session attendance did not improve odds of 12-month WL success. Medicare-eligible adults ≥65 years were more likely to meet the 12-month WL goal (odds ratio = 3.03, 95% CI, 1.58-5.81) versus <65 years.

Conclusions

The results of this study provide important information regarding participant attendance and WL for providers offering DPP-based lifestyle intervention programs across the country who are seeking Medicare reimbursement. Understanding Medicare reimbursement-defined success will allow these providers to focus on and develop strategies to enhance program effectiveness and sustainability.

在基于社区的糖尿病预防计划干预中，维持会议出席率和早期减肥目标实现对减肥成功的影响

目的

本研究的目的是检查参加基于社区的糖尿病预防计划 (DPP) 生活方式干预的老年人的维持课程出席率和 6 个月体重减轻 (WL) 目标实现如何影响 12 个月 5% WL 成功率。

方法

数据来自 2 项社区试验，这些试验向患有前驱糖尿病和/或代谢综合征的超重/肥胖成人（平均年龄 = 62 岁，76% 为女性）提供基于 DPP 的群体生活方式平衡 (GLB) 的 12 个月社区试验。包括的参与者 (n = 238) 参加了≥4 次核心会议（0-6 个月），并拥有完整的维护出席数据（7-12 个月期间 6 次会议中的 4 次以上）以及 6 个月和 12 个月的 WL（5% WL 目标，是/否）。使用多变量逻辑回归来估计 12 个月 5% WL 与维持出勤率和 6 个月 WL 相关的几率。检查了年龄（符合Medicare 资格的≥65 岁与<65 岁）与WL 和出勤率之间的关联。

结果

参加≥4 次维护会议和达到 6 个月 5% WL 目标都增加了达到 12 个月 5% WL 目标的几率。对于那些没有达到 6 个月 WL 目标的人，参加维护课程并没有提高 12 个月 WL 成功的几率。≥65 岁符合医疗保险条件的成年人更有可能达到 12 个月的 WL 目标（优势比 = 3.03，95% CI，1.58-5.81）与 <65 岁相比。

结论

本研究的结果为在全国范围内寻求医疗保险报销的基于 DPP 的生活方式干预计划的提供者提供了有关参与者出勤率和 WL 的重要信息。了解医疗保险报销定义的成功将使这些提供者能够专注于并制定策略以提高计划的有效性和可持续性。
