Abstract

Background: Reducing sugar-sweetened beverages (SSB) is a worldwide public health priority. There are United States regions with notable SSB consumption pattern disparities, including Appalachia.

Objectives: We aimed to measure the efficacy of a digital behavioral intervention in reducing SSB consumption. Weight and quality of life (QOL) were also explored.

Methods: In this 2-group randomized-controlled trial targeting adults living in Appalachia, participants were randomly assigned to either an interactive, structured, digital intervention comprised of 6 cores, behavioral tracking, and personalized action planning, or a static patient education website. At baseline and at 9-wk and 6-mo postintervention, validated measures were used to assess SSB intake and QOL. Weight was captured using cellular-enabled scales.

Results: Participants (n = 249) were 88% Caucasian, 83% female, 52% with income <$55,000/y, 86% from more rural counties, and 84% with overweight or obesity. In the digital intervention group, the mean core completion was 5.2 [standard deviation (SD) = 1.6] of 6 cores, and participants tracked a mean of 76% (SD = 29%) of daily SSB diaries and 57% (SD = 31%) of daily weights. At 9-wk, digital intervention participants [-896.1 mL/d; 95% confidence interval (CI): -1043.9, -748.2 mL/d] consumed 289.8 (95% CI: -493.9, -88.7) less SSB mL/d than comparison participants (-606.3 mL/d; 95% CI: -745.3, -467.9 mL/d) [effect size (ES) = 0.37; P = 0.005]. The 6-mo assessment was similar, with digital intervention participants consuming an average of 280.9 (95% CI: -490.9, -68.0) less SSB mL/d than comparison participants (ES = 0.35; P = 0.009). There was no significant between-condition QOL effects, yet QOL improved within both conditions (P < 0.001). At 6-mo, body weight was significantly reduced for digital intervention relative to comparison participants (ES = 0.23; P = 0.046).

Conclusions: A digital behavioral intervention was efficacious in reducing SSB consumption among Appalachian adults and yielded high engagement and retention rates. This intervention should be evaluated in other populations with excessive SSB consumption. This trial was registered at clincialtrials.gov as NCT05030753.

减少含糖饮料消费的数字行为干预：一项随机对照试验。

背景：减少含糖饮料（SSB）是世界范围内的公共卫生重点。美国一些地区的SSB消费模式存在显著差异，包括阿巴拉契亚地区。目的：我们旨在衡量数字行为干预在减少SSB消费方面的效果。体重和生活质量（QOL）也进行了探讨。方法：在这项针对生活在阿巴拉契亚地区的成年人的两组随机对照试验（RCT）中，参与者被随机分配到由六个核心组成的交互式、结构化、数字干预、行为跟踪和个性化行动计划或静态患者教育网站。在基线、干预后9周和6个月，采用有效的措施评估SSB摄入量和生活质量。重量是用细胞秤捕获的。结果：参与者（n=249） 88%为高加索人，83%为女性，52%为收入人群。结论：数字化行为干预可有效减少阿巴拉契亚成年人的SSB消费，并产生较高的参与度和保留率。这种干预措施应在其他SSB消费过量的人群中进行评估。试验注册：Clincialtrials.gov: NCT05030753。注册于2021年8月13日。https://clinicaltrials.gov/study/NCT05030753。

期刊介绍： American Journal of Clinical Nutrition is recognized as the most highly rated peer-reviewed, primary research journal in nutrition and dietetics.It focuses on publishing the latest research on various topics in nutrition, including but not limited to obesity, vitamins and minerals, nutrition and disease, and energy metabolism. Purpose: The purpose of AJCN is to: Publish original research studies relevant to human and clinical nutrition. Consider well-controlled clinical studies describing scientific mechanisms, efficacy, and safety of dietary interventions in the context of disease prevention or health benefits. Encourage public health and epidemiologic studies relevant to human nutrition. Promote innovative investigations of nutritional questions employing epigenetic, genomic, proteomic, and metabolomic approaches. Include solicited editorials, book reviews, solicited or unsolicited review articles, invited controversy position papers, and letters to the Editor related to prior AJCN articles. Peer Review Process: All submitted material with scientific content undergoes peer review by the Editors or their designees before acceptance for publication.
