Public health interventions are cost-effective methods to reduce heart disease. The present study investigated the impact of a low-cost priming technique on a public health campaign targeting cardiovascular risk. Participants were 415 individuals (66% female) ages 18 and older recruited through clinics and churches. The study consisted of three phases. In Phase I, participants completed a brief survey to assess knowledge of the cardiovascular health indicators. The survey served as the prime (intervention) for the study. At Phase II, participants were provided with access to a public health campaign consisting of an education brochure on cardiovascular health. Following the educational campaign, all participants completed a post-campaign survey in Phase III of the study. Participants who completed the surveys in both Phase I and III were placed in the intervention condition (26%) and those who only completed the Phase III survey were placed in the control condition (74%). Participants who were primed reported greater awareness of the public health campaign. Additionally, more intervention participants reported they had knowledge of their own and the normal ranges for cholesterol, glucose, and body mass index. For participants who were aware of the health promotion campaign, more participants in the primed group indicated they had knowledge of their own cholesterol and glucose levels and had made positive lifestyle changes as a result of the campaign. Results suggest the presence of a priming effect. Public health campaigns may benefit from the inclusion of a low-cost prime prior to intervention.
公共卫生干预措施是降低心脏病成本效益的方法。本研究调查了一种低成本启动技术对针对心血管风险的公共卫生运动的影响。参与者为 415 名年龄在 18 岁及以上的个体，通过诊所和教堂招募。研究分为三个阶段。在第一阶段，参与者完成了一项简短的调查，以评估他们对心血管健康指标的了解程度。该调查是该研究的启动（干预）。在第二阶段，参与者可以访问一个公共卫生运动，其中包括一份心血管健康教育手册。在教育运动之后，所有参与者在研究的第三阶段完成了一次运动后调查。在第一阶段和第三阶段完成调查的参与者被置于干预条件下（26%），而仅完成第三阶段调查的参与者被置于对照组（74%）。接受启动的参与者报告对公共卫生运动的认识有所提高。此外，更多的干预参与者报告说，他们了解自己的胆固醇、葡萄糖和体重指数的正常范围。对于了解健康促进运动的参与者，更多的启动组参与者表示，他们了解自己的胆固醇和葡萄糖水平，并因该运动而做出了积极的生活方式改变。结果表明存在启动效应。公共卫生运动可能受益于在干预之前包含低成本的启动。
