BACKGROUND
Often perceived as a safer smoke, Natural American Spirit (NAS) may find particular appeal in communities with strong non-smoking norms. We hypothesized NAS would be more popular in cities with lower smoking prevalence, with the pattern unique to NAS. We tested household income, cigarette taxes, and young adult population as alternative correlates and examined brand specificity, relative to Marlboro and Pall Mall.
METHODS
Using proprietary, city-specific sales estimates obtained from Nielsen for 30 U.S. cities over one year (9/7/18-9/9/19), we computed cigarette sales volume as standard pack units per 10,000 adult smokers for NAS and Marlboro and Pall Mall. Linear regression models examined associations between city-level sales volume and adult smoking prevalence, median household income, the sum of state/local cigarette excise taxes, and young adult population.
RESULTS
NAS sales volume averaged 44,785 packs per 10,000 adult smokers (SD = 47,676). Across 30 cities, adult smoking prevalence averaged 18.0% (SD = 4.5%), median household income averaged $53,677 (SD = $14,825), cigarette excise tax averaged $2.55 (SD = $1.63), and young adult population averaged 10.6% (SD = 2.2%). NAS sales volume was greater in cities with lower adult smoking prevalence (β = -0.39, 95% CI[-0.74, -0.03], p = 0.034), a pattern that was not observed for Marlboro or Pall Mall (ps > 0.356). Marlboro (β = -0.40, 95% CI[-0.76, -0.05], p = 0.027) and Pall Mall (β = -0.48, 95% CI[-0.82, -0.14], p = 0.008) sales volumes were higher in cities where cigarette excise taxes were lower, a pattern not observed for NAS (p = 0.224).
CONCLUSION
NAS appears to be more popular in cities with lower smoking prevalence and may deter efforts to further decrease prevalence.
背景
天然美国精神（NAS）香烟常被视为危害较小的香烟，在有着严格禁烟规范的社区可能特别有吸引力。我们假设NAS在吸烟率较低的城市会更受欢迎，且这种模式是NAS独有的。我们检验了家庭收入、香烟税和年轻成年人口作为替代关联因素，并相对于万宝路和长红品牌研究了其品牌特异性。
方法
使用从尼尔森公司获取的针对美国30个城市一年（2018年9月7日至2019年9月9日）特定城市的专有销售估计数据，我们计算了NAS、万宝路和长红每10000名成年吸烟者的香烟销售量（以标准包为单位）。线性回归模型检验了城市层面销售量与成年吸烟率、家庭收入中位数、州/地方香烟消费税总和以及年轻成年人口之间的关联。
结果
NAS的销售量平均为每10000名成年吸烟者44785包（标准差 = 47676）。在30个城市中，成年吸烟率平均为18.0%（标准差 = 4.5%），家庭收入中位数平均为53677美元（标准差 = 14825美元），香烟消费税平均为2.55美元（标准差 = 1.63美元），年轻成年人口平均为10.6%（标准差 = 2.2%）。在成年吸烟率较低的城市中，NAS的销售量更高（β = -0.39，95%置信区间[-0.74, -0.03]，p = 0.034），万宝路或长红则未观察到这种模式（p值 > 0.356）。在香烟消费税较低的城市中，万宝路（β = -0.40，95%置信区间[-0.76, -0.05]，p = ；0.027）和长红（β = -0.48，95%置信区间[-0.82, -0.14]，p = 0.008）的销售量更高，NAS未观察到这种模式（p = 0.224）。
结论
NAS在吸烟率较低的城市似乎更受欢迎，可能会阻碍进一步降低吸烟率的努力。
