据报道，非裔美国人(AAs)在健康研究中的流失率更高。然而，人们对哪些AA更容易退学及其原因知之甚少。一个尚未被探索的潜在预测因素是种族认同(EI)。这项研究考察了在参加健康促进干预以增加水果和蔬菜摄入量的AA中，EI与随访损失之间的关系。来自亚特兰大和底特律两个综合医疗保健提供系统的560名AA成年人参加了一项随机干预试验。在基线时，所有参与者被分为六个EI核心组：非洲中心组、美国黑人、双文化组、多元文化组、同化组和高度文化不信任组。我们根据这些EI类型检查了失访失败率。总体而言，92名参与者(16%)失去了随访。在被归类为非中心的患者中，失访率(24%)高于没有非中心身份的患者(13%)。在调整协变量后，非中心型参与者失去随访的可能性是没有这种身份类型的参与者的1.9倍(CI：1.1-3.6)。在研究研究中评估AA的EI可能有助于确定有辍学和/或无反应风险的群体。
Higher rates of attrition in health research have been reported for African Americans (AAs). However, little is known about which AAs are more prone to drop out and why. One potential predictor that has not been explored is Ethnic Identity (EI). This study examined the association between EI and loss-to-follow-up among AAs enrolled in a health promotion intervention to increase fruit and vegetable intake. Five hundred and sixty AA adults from two integrated health care delivery systems in Atlanta and Detroit were enrolled into a randomized intervention trial. At baseline, all participants were classified into six EI core groups: Afrocentric, Black American, Bicultural, Multicultural, Assimilated, and High Cultural Mistrust. We examined loss-to-follow-up rates by these EI type. Overall, 92 participants (16%) were lost to follow up. Loss-to-follow-up rates were higher among those classified as Afrocentric (24%) than those without an Afrocentric identity (13%). After adjustment for covariates, Afrocentric participants were 1.9 times (CI: 1.1 – 3.6) more likely to be lost to follow up than participants without this identity type. Assessing EI of AAs in research studies may help identify groups at risk for dropout and/or non-response.
