To determine common themes used by US tobacco industry witnesses pertaining to youth smoking initiation during litigation in the United States.
Qualitative thematic analysis of transcripts from 29 tobacco litigation cases dating from 1992 to 2002.
Youth smoking is portrayed by the tobacco industry as a source of great concern to them. Youth smoking prevention programmes developed by US tobacco companies are supposedly intended to delay decision-making about smoking until age 18, when individuals are then seen to be of an age where they are able to "choose to smoke". Tobacco industry media campaigns, youth access, community and school-based programmes are predicated on peer influence, parental factors, and commercial access being the primary influences on youth smoking uptake, rather than tobacco marketing, inaccurate risk appraisal, price and other factors known to influence youth smoking. Despite substantial financial investment in tobacco industry programmes, their witnesses were able to describe only weak evaluation methods, being preoccupied with measures of message comprehension, programme reach and uptake, and the associated costs of their efforts, rather than any evaluation designed to assess effects on youth smoking behaviour.
Stated concerns about youth smoking and youth smoking prevention programmes are put forward in litigation as evidence that the tobacco industry is "serious" about tackling youth smoking, and serve as a primary strategy to improve the tobacco industry's public image. The tobacco industry's evaluation of the effectiveness of their youth smoking prevention programmes is demonstrably insufficient under current public health evaluation standards. Public health and welfare agencies should avoid engagement with tobacco industry-sponsored programmes.
确定美国烟草行业证人在美国诉讼期间提及的与青少年吸烟起始相关的共同主题。
对1992年至2002年期间29起烟草诉讼案的庭审记录进行定性主题分析。
烟草行业将青少年吸烟描绘成他们极为关注的问题。美国烟草公司制定的青少年吸烟预防计划据称旨在将吸烟决策推迟到18岁,届时人们被视为已到能够“选择吸烟”的年龄。烟草行业的媒体宣传活动、青少年接触途径、社区和学校项目基于同伴影响、父母因素以及商业接触是青少年吸烟行为的主要影响因素,而非烟草营销、不准确的风险评估、价格及其他已知影响青少年吸烟的因素。尽管烟草行业在项目上投入了大量资金,但其证人只能描述一些薄弱的评估方法,主要关注信息理解、项目覆盖范围和参与情况的衡量指标以及相关成本,而非旨在评估对青少年吸烟行为影响的任何评估。
在诉讼中提出对青少年吸烟及青少年吸烟预防项目的所谓担忧,作为烟草行业“认真”应对青少年吸烟问题的证据,并作为改善烟草行业公众形象的主要策略。按照当前公共卫生评估标准,烟草行业对其青少年吸烟预防项目有效性的评估明显不足。公共卫生和福利机构应避免参与烟草行业赞助的项目。
