公屋居民对添加糖的摄入量很高，这与他们社交网络中的含糖饮料(SSB)消费有关。在这项可行性研究中，我们设计并测试了一种面向网络的干预措施，通过鼓励减少SSB消费来减少添加糖的摄入量。我们进行了为期6个月的单臂试验，测试了一个小组课程(9个课程)，该课程结合了行为改变策略，通过促进减少SSB与同伴接触的方法来减少添加糖的摄入量。我们招募和培训公共住房居民成为“同伴教育者”，然后他们与他们的网络成员交流信息并做出改变，以减少SSB。我们计算了参加小组会议的中位数，并确定了对该计划满意的个人百分比。我们使用5因素膳食筛选器估计添加糖的摄入量，并使用Wilcoxon符号等级检验比较基线和6个月的中位数。我们招募了17名居民及其17名网络成员(n=34)。平均年龄为45.7岁，其中79.4%为女性，97.1%为非裔美国人。参加会议的中位数为9次(四分位数范围为4-9次)，88.2%的人对该计划非常满意。总体而言，基线添加糖摄入量中位数为38.0茶匙/天，在6个月时显著下降至17.2茶匙/天(P<；.001)。居民和网络成员在6个月后取得了类似的结果(分别为17.4TSP/天和16.9TSP/天)。总之，我们的结果表明，旨在减少SSB摄入量的社会网络干预是可行的，并且可以显著减少成人添加糖的摄入量，这值得在随机对照试验中进行进一步的研究。
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 (P < .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.
