Abstract

Background: Reducing tobacco retailer availability is a key tobacco endgame policy. The development and evaluation of retail-based policies require spatial methodologies. We modelled the prevalence of adult cigarette and electronic nicotine delivery system (ENDS) use according to tobacco retailer density, considering geographical variations.

Methods: Registration data for tobacco retail businesses, a population-representative survey of South Koreans aged ≥19 years, and population and land area data were used. We merged the datasets according to geographical units. Ordinary least squares (OLS) and geographically weighted regression (GWR) analyses were conducted to model cigarette and ENDS use prevalence, respectively.

Findings: Tobacco retailer density was associated with increased cigarette use prevalence in the OLS model (β=2.19, p=0.02). A 1.9-fold difference by region was identified for the coefficient, indicating an association with tobacco retailer density (minimum 1.39, maximum 2.65), in the GWR analysis. No significant association was present between tobacco retailer density and ENDS prevalence in either the OLS (β=0.24, p=0.37) or the GWR model (minimum 0.20, maximum 0.28).

Conclusion: Our results suggest the importance of using spatial methods to develop and evaluate retail-based endgame policies. The establishment of tobacco retailer databases by the introduction of licensing is necessary to develop and evaluate the effectiveness of tobacco retailer regulations.

使用地理加权回归模型为韩国零售业的终局策略提供信息:对香烟和ENDS流行率的应用。
背景:减少烟草零售商的供应是烟草业的一项关键政策。制定和评估基于零售业的政策需要空间方法。我们根据烟草零售商的密度,考虑到地理差异,对成人香烟和电子尼古丁输送系统(ENDS)的使用率进行了建模。方法:使用烟草零售企业的注册数据、对≥19岁的韩国人的人口代表性调查以及人口和土地面积数据。我们根据地理单位合并了数据集。分别进行了普通最小二乘法(OLS)和地理加权回归法(GWR)分析,以模拟香烟和ENDS的使用流行率。研究结果:在OLS模型中,烟草零售商密度与吸烟率的增加有关(β=2.19,p=0.02)。在GWR分析中,该系数按地区差异1.9倍,表明与烟草零售商密度有关(最小1.39,最大2.65)。在OLS(β=0.24,p=0.37)或GWR模型(最小0.20,最大0.28)中,烟草零售商密度与ENDS患病率之间没有显著关联。结论:我们的研究结果表明,使用空间方法制定和评估基于零售的终局政策很重要。通过引入许可证建立烟草零售商数据库对于制定和评估烟草零售商法规的有效性是必要的。
