Mass media campaigns are an effective population-level intervention for preventing tobacco use. However, little evidence exists for whether these campaigns similarly influence demographic subgroups. This study examined the effects of the truth® campaign to reduce tobacco use among demographic subgroups. We used data from a national, continuous, cross-sectional tracking survey of 15–24-year-olds (n = 32 331). We used a measure of weekly aggregated campaign exposure to assess whether cigarette smoking intentions and current cigarette use varied by race/ethnicity, financial situation and population density subgroups, controlling for factors known to be associated with tobacco use. Examining estimates across subgroup categories in light of the overall model estimates revealed that the effects of week-level campaign exposure on cigarette smoking intentions and current cigarette use were similar across subgroups. Wald tests of equality across estimates in each subgroup suggested that the estimates did not differ from one another in any given instance. The truth campaign does not differ significantly in its capacity to prompt declines in tobacco use across a broad spectrum of US youth and young adults. Mass media tobacco prevention campaigns can be an effective and critical component of a comprehensive tobacco control program, particularly with respect to reducing tobacco-related disparities among demographic subgroups.

全国反烟草预防运动对人口亚群的影响的证据

大众媒体运动是预防烟草使用的有效人群干预措施。然而，几乎没有证据表明这些运动是否同样影响人口亚群。本研究检验了 truth® 运动对减少人口亚群烟草使用的影响。我们使用了一项针对 15-24 岁的全国性、连续性、横断面跟踪调查的数据（n = 32 331）。我们使用每周汇总的活动暴露量来评估吸烟意图和当前卷烟使用是否因种族/民族、财务状况和人口密度亚组而异，控制已知与烟草使用相关的因素。根据总体模型估计检查跨亚组类别的估计显示，周级活动暴露对吸烟意图和当前卷烟使用的影响在亚组中是相似的。Wald 对每个子组中估计值的相等性检验表明，在任何给定情况下，估计值之间没有差异。真相运动在促使广泛的美国青年和年轻人减少烟草使用的能力方面没有显着差异。大众媒体烟草预防运动可以成为全面烟草控制计划的有效和关键组成部分，特别是在减少人口亚群之间与烟草相关的差异方面。Wald 对每个子组中估计值的相等性检验表明，在任何给定情况下，估计值之间没有差异。真相运动在促使广泛的美国青年和年轻人减少烟草使用的能力方面没有显着差异。大众媒体烟草预防运动可以成为全面烟草控制计划的有效和关键组成部分，特别是在减少人口亚群之间与烟草相关的差异方面。Wald 对每个子组中估计值的相等性检验表明，在任何给定情况下，估计值之间没有差异。真相运动在促使广泛的美国青年和年轻人减少烟草使用的能力方面没有显着差异。大众媒体烟草预防运动可以成为全面烟草控制计划的有效和关键组成部分，特别是在减少人口亚群之间与烟草相关的差异方面。
