这项研究的目的是检查旨在促进美国拉丁裔健康的非专业健康顾问(LHA)计划，以及仅限教育者和教育者加桥梁计划在设计和实现结果方面的差异程度。两位独立编码者回顾了128篇已发表的关于LHA的文章，这些文章产生了两个水平的信息：(I)研究设计和参与者以及LHA特征，来自61项研究，这些研究广泛比较了纯教育者计划和教育者+桥梁计划；(Ii)17项随机对照试验或带有结果数据的准实验研究的实施特征和结果。LHA计划在美国某些地区广泛应用于拉丁裔；我们的研究结果表明，LHA是有效的干预媒介。我们确定了仅针对教育者的LHA计划和教育者+桥梁的LHA计划之间的差异，尽管具有结果数据的少数教育者+桥梁计划的比较有限。针对墨西哥移民/墨西哥裔美国人以外的拉丁裔亚群的研究仍然存在重大差距。充分的研究已经评估了拉丁美洲人的LHA计划，评估他们实现健康行为和/或健康状况改变的能力。今后，有必要更多地关注组织和政策的变化。LHA的特点和作用的多样性仍然存在问题，这不仅影响到结果，而且影响到方案的可持续性和传播。
The objective of this study was to examine lay health advisor (LHA) programs designed to promote health among US Latinos and the extent to which educator-only versus educator-plus-bridge programs differed in designs and outcomes achieved. Two independent coders reviewed 128 published articles on LHAs yielding information at two levels: (i) study design and participant and LHA characteristics from 61 studies that broadly compared educator-only versus educator-plus-bridge programs and (ii) implementation features and outcomes from 17 randomized controlled trials or quasi-experimental studies with outcome data. LHA programs have been widely used with Latinos in certain US regions; our findings indicate that LHAs are effective intervention agents. We identified differences between educator-only and educator-plus-bridge LHA programs, although the small number of educator-plus-bridge programs with outcome data limited comparisons. Major gaps remain in research targeting Latino subgroups other than Mexican immigrants/Mexican Americans. Sufficient research has evaluated LHA programs among Latinos on their ability to achieve health behavior and/or health status changes. In the future, more of a focus on organizational and policy changes is warranted. Questions remain about diversity in LHAs' characteristics and roles, which influence not only outcomes but also program sustainability and dissemination.
