Public housing residents have high intake of added sugars, which is associated with sugar-sweetened beverage (SSB) consumption in their social networks. In this feasibility study, we designed and tested a network-oriented intervention to decrease added sugar intake by encouraging reduced SSB consumption. We conducted a 6-month single-arm trial testing a small-group curriculum (9 sessions) that combined behavior change strategies to reduce added sugar intake by promoting SSB reduction with a peer outreach approach. We recruited and trained public housing residents to be "Peer Educators," who then communicated information and made changes to reduce SSB with their network members. We calculated the median number of group sessions attended and determined the percentage of individuals satisfied with the program. We estimated added sugar intake using a 5-factor dietary screener and compared baseline and 6-month median values using Wilcoxon signed rank tests. We recruited 17 residents and 17 of their network members (n = 34). Mean age was 45.7 years, 79.4% were women, and 97.1% were African American. Median number of sessions attended was 9 (interquartile range: 4-9), and 88.2% were very satisfied with the program. Overall, baseline median added sugar intake was 38.0 tsp/day, which significantly declined to 17.2 tsp/day at 6 months ( < .001). Residents and network members achieved similar results at 6 months (17.4 vs 16.9 tsp/day, respectively). In conclusion, our results demonstrate that a social network intervention aimed at reducing SSB consumption is feasible and can produce significant decreases in adult added sugar intake, which warrants further investigation in a randomized controlled trial.
公共住房居民摄入的添加糖量很高，这与他们社交网络中含糖饮料（SSB）的消费有关。在这项可行性研究中，我们设计并测试了一种以网络为导向的干预措施，通过鼓励减少SSB消费来降低添加糖的摄入量。我们进行了一项为期6个月的单臂试验，测试了一个小组课程（9节），该课程结合了行为改变策略，通过同伴推广方法促进减少SSB来降低添加糖的摄入量。我们招募并培训了公共住房居民成为“同伴教育者”，然后他们与自己社交网络中的成员交流信息并做出改变以减少SSB的消费。我们计算了参加小组课程的中位数，并确定了对该项目满意的个体百分比。我们使用五因素饮食筛查工具估计添加糖的摄入量，并使用Wilcoxon符号秩检验比较基线和6个月时的中位数。我们招募了17名居民及其17名社交网络成员（n = 34）。平均年龄为45.7岁，79.4%为女性，97.1%为非裔美国人。参加课程的中位数为9节（四分位间距：4 - 9），88.2%的人对该项目非常满意。总体而言，基线时添加糖的中位数摄入量为38.0茶匙/天，在6个月时显著降至17.2茶匙/天（P <.001）。居民和社交网络成员在6个月时取得了相似的结果（分别为17.4和16.9茶匙/天）。总之，我们的结果表明，旨在减少SSB消费的社交网络干预是可行的，并且可以使成年人添加糖的摄入量显著降低，这值得在随机对照试验中进一步研究。
