Purpose:The purpose of the study was to explore the feasibility of using commonly available technology, such as text messaging, for diabetes prevention in rural Mexican American communities during COVID-19.Methods:Participants were selected from a diabetes prevention study funded by the National Institutes of Health that, prior to COVID-19, involved in-person group intervention sessions. Participants were predominantly female adults born in Mexico and Spanish-speaking. A subsample (n = 140) was divided into 3 cohorts: (1) 50 who completed the initial in-person intervention prior to the COVID-19 research pause, (2) 60 who needed additional support sessions to complete the intervention and thus received 10 text messages with links to relevant online diabetes prevention videos (TM+), and (3) 30 who received enhanced usual care involving health guidance offered during data collection (control). Repeated measures analysis of covariance was used to evaluate cohort differences at 24 months post baseline.Results:No significant cohort differences were found for depression, eating self-efficacy, alcohol intake, fat avoidance, or sedentary behaviors. Differences in A1C showed both in-person and TM+ cohorts having lower mean A1C levels (5.5%) than the control cohort (5.7%). The TM+ cohort had lower body mass index than other cohorts and a lower diabetes conversion rate (22.2%) compared to the control cohort (28%). Participants indicated preferences for in-person/TM+ combination interventions. The strongest positive feedback was for the TM+ intervention cooking demonstration videos.Conclusions:Augmented text messaging combined with in-person sessions had similar outcomes to the all in-person strategy and thus has the potential for expanding the reach of diabetes prevention to many Mexican American communities.

在患有糖尿病前期的墨西哥裔美国人中，在 COVID-19 期间从面对面干预过渡到增强短信：斯塔尔县糖尿病预防随机临床试验

目的：本研究的目的是探索在 COVID-19 期间使用常用技术（例如短信）在墨西哥裔美国农村社区预防糖尿病的可行性。方法：参与者选自国家资助的糖尿病预防研究在 COVID-19 之前，卫生研究院参与了面对面的团体干预课程。参与者主要是出生在墨西哥且讲西班牙语的女性成年人。子样本 (n = 140) 被分为 3 个队列：(1) 50 名在 COVID-19 研究暂停之前完成了初步面对面干预的人，(2) 60 名需要额外支持课程来完成干预并因此接受治疗的人10 条短信，其中包含相关在线糖尿病预防视频 (TM+) 的链接，以及 (3) 30 名患者接受了加强的常规护理，包括在数据收集期间提供的健康指导（对照）。使用协方差的重复测量分析来评估基线后 24 个月的队列差异。结果：在抑郁、饮食自我效能、酒精摄入、避免脂肪或久坐行为方面没有发现显着的队列差异。A1C 的差异显示，面对面队列和 TM+ 队列的平均 A1C 水平 (5.5%) 低于对照队列 (5.7%)。与对照组 (28%) 相比，TM+ 队列的体重指数低于其他队列，糖尿病转化率 (22.2%) 也较低。参与者表示偏好面对面/TM+ 组合干预。最强烈的积极反馈是 TM+ 干预烹饪演示视频。结论：增强短信与面对面会议相结合，与全面对面策略具有相似的结果，因此有可能将糖尿病预防的范围扩大到许多墨西哥裔美国人社区。
