Racial and ethnic disparities in response to direct-to-consumer advertising (DTCA) of pharmaceuticals were studied.
Using national survey data of 2814 Americans, Hispanics and African Americans were compared to whites with respect to their exposure and response to DTCA. A 20-minute telephone survey collected basic demographic information from each respondent. Exposure to DTCA was measured by asking if individuals had seen or heard an advertisement for a prescription within the past 12 months. Those who had were asked about their responses to DTCA. Participants' perceptions of the role of DTCA were also examined. Six different variables were used to measure perceived health benefits of DTCA exposure. Exploratory analyses were performed to detect differences, and multivariate logistic regression was conducted to test whether race or ethnicity remained significant in explaining differences while controlling for other personal factors.
Hispanics and African Americans were less likely than whites to be exposed to DTCA, more likely to be influenced by DTCA, and more positive about the health benefits of DTCA exposure. African Americans were also more likely to ask their physicians for a drug advertised via DTCA and have their request refused, which raises an issue about the impact of DTCA on provider-patient relationships.

研究了直接面向消费者的药品广告(DTCA)在不同种族和族裔群体中的反应差异。
利用对 2814 名美国白种人、西班牙裔和非裔美国人的全国性调查数据,比较了这些群体在接触和对 DTCA 的反应方面与白种人之间的差异。通过电话调查,在 20 分钟内收集了每位受访者的基本人口统计信息。通过询问受访者是否在过去 12 个月内看到或听到过处方药广告来衡量他们接触 DTCA 的情况。对于那些有过接触的人,询问他们对 DTCA 的反应。还研究了参与者对 DTCA 作用的看法。使用了六个不同的变量来衡量对 DTCA 接触的感知健康益处。进行了探索性分析以发现差异,并进行多元逻辑回归分析,以检验在控制其他个人因素的情况下,种族或族裔是否仍然是解释差异的重要因素。
西班牙裔和非裔美国人接触 DTCA 的可能性低于白种人,受 DTCA 的影响更大,对 DTCA 接触的健康益处的看法更为积极。非裔美国人也更有可能向他们的医生要求通过 DTCA 广告宣传的药物,但他们的要求被拒绝了,这引发了关于 DTCA 对医患关系影响的问题。
