We examined the influence of tobacco outlet density and residential proximity to tobacco outlets on continuous smoking abstinence 6 months after a quit attempt.
We used continuation ratio logit models to examine the relationships of tobacco outlet density and tobacco outlet proximity with biochemically verified continuous abstinence across weeks 1, 2, 4, and 26 after quitting among 414 adult smokers from Houston, Texas (33% non-Latino White, 34% non-Latino Black, and 33% Latino). Analyses controlled for age, race/ethnicity, partner status, education, gender, employment status, prequit smoking rate, and the number of years smoked.
Residential proximity to tobacco outlets, but not tobacco outlet density, provided unique information in the prediction of long-term, continuous abstinence from smoking during a specific quit attempt. Participants residing less than 250 meters (P = .01) or less than 500 meters (P = .04) from the closest tobacco outlet were less likely to be abstinent than were those living 250 meters or farther or 500 meters or farther, respectively, from outlets.
Because residential proximity to tobacco outlets influences smoking cessation, zoning restrictions to limit tobacco sales in residential areas may complement existing efforts to reduce tobacco use.
我们考察了烟草销售点密度和居住场所与烟草销售点的接近程度对戒烟尝试后 6 个月连续戒烟的影响。
我们使用延续比例对数模型，分析了在德克萨斯州休斯顿的 414 名成年吸烟者中，在戒烟后第 1、2、4 和 26 周，每周通过生物化学方法验证的连续戒烟率与烟草销售点密度和烟草销售点接近程度之间的关系。（33%为非拉丁裔白人，34%为非拉丁裔黑人，33%为拉丁裔）。分析控制了年龄、种族/民族、伴侣状况、教育程度、性别、就业状况、戒烟前吸烟率和吸烟年数。
居住场所与烟草销售点的接近程度，而不是烟草销售点密度，为预测特定戒烟尝试期间长期、持续戒烟提供了独特的信息。与居住在距离最近的烟草销售点 250 米或更远或 500 米或更远的参与者相比，居住在距离最近的烟草销售点不足 250 米（P=0.01）或不足 500 米（P=0.04）的参与者戒烟的可能性较低。
由于居住场所与烟草销售点的接近程度会影响戒烟，因此限制在居民区销售烟草的分区限制可能会补充现有的减少烟草使用的努力。
