目的：许多有针对性的干预措施已经开发出来，并在非洲裔美国人（AA）中进行了测试；然而，aa是一个高度异质性的群体。不同aa的一个特征是种族认同（EI）。很少有人研究如何将El纳入健康信息和计划的设计中。设计：我们测试了对El进行基于印刷的水果和蔬菜（f&v）干预是否会增强项目的影响。研究人员从两个综合医疗保健服务系统中招募了AA成人，然后随机接收三份关于三个月内F & V行为改变的通讯。一组通讯仅针对人口统计和社会认知变量（控制条件）进行定制，而另一组（实验条件）则针对El进行定制。主要结果测量：本研究的主要结果是f&v摄入量，在基线和三个月后使用两种简短的自我报告频率测量的组合进行评估。结果：共纳入560例符合条件的受试者，其中468例提供了完整的3个月随访数据。与对照组相比，实验组每天的平均食物和饮料摄入量增加了1.1份。对照组为8份（p = .13）。非中心实验组的参与者显示，与非中心实验组的参与者相比，他们每天的饮食量增加了1.4倍。非洲中心对照组每天增加43份（p < 0.05）。结论：尽管总体组间效应不显著，但定制饮食信息对种族身份的影响可能会改善某些AA亚组的干预效果。
Objective: Many targeted interventions have been developed and tested with African Americans (AA); however, AAs are a highly heterogeneous group. One characteristic that varies across AAs is Ethnic Identity (EI). Little research has been conducted on how to incorporate El into the design of health messages and programs. Design: We tested whether tailoring a print-based fruit and vegetable (F & V) intervention on El would enhance program impact. AA adults were recruited from two integrated healthcare delivery systems and then randomized to receive three newsletters focused on F & V behavior change over three months. One set of newsletters was tailored only on demographic and social cognitive variables (control condition), whereas the other (experimental condition) was additionally tailored on El. Main Outcome Measures: The primary outcome for the study was F & V intake, assessed at baseline and three months later using the composite of two brief self-report frequency measures. Results: A total of 560 eligible participants were enrolled, of which 468 provided complete 3-month follow-up data. The experimental group increased their daily mean F & V intake by 1.1 servings compared to .8 servings in the control group (p = .13). Afrocentric experimental group participants showed a 1.4 increase in F & V servings per day compared to a .43 servings per day increase among Afrocentric controls (p < .05). Conclusions: Although the overall between-group effects were not significant, tailoring dietary messages on ethnic identity may improve intervention impact for some AA subgroups.
