To compare the retail distribution and density per population of electronic and conventional cigarettes in smoke-free communities with and without e-cigarette restrictions.
A cross-sectional study with field observations of retail tobacco stores.
Two Central Kentucky counties with 100% smoke-free workplace regulations; counties selected on the basis of whether e-cigarette use was restricted.
Fifty-seven tobacco retailers in two counties, including conventional retailers and stand-alone e-cigarette stores.
Type and location of store and products sold; addresses of stores and schools geocoded with ArcGIS.
Bivariate comparisons between counties, rates and confidence intervals for frequency of tobacco retailers and e-cigarette stores per population.
Fifty-three percent of tobacco retailers sold e-cigarettes. E-cigarette availability did not differ by whether smoke-free regulation covered e-cigarettes. Rates of tobacco retailers and e-cigarette distributors per 10,000 were 8.29 and 4.40, respectively, in the two-county area. Of the 40 schools, 88% had a tobacco retailer and 68% had an e-cigarette distributor within 1 mile.
In this exploratory study, e-cigarette use restriction was not related to store availability. For a relatively new product, e-cigarettes were readily available in retail outlets and close to schools.
比较有无电子烟限制的无烟社区中电子烟和传统香烟的零售分布及人均密度。
一项对零售烟草商店进行实地观察的横断面研究。
肯塔基州中部的两个县，有100%的无烟工作场所规定；根据电子烟使用是否受限来选择这些县。
两个县的57家烟草零售商，包括传统零售商和独立电子烟商店。
商店类型、位置及所售产品；用ArcGIS对商店和学校地址进行地理编码。
两县之间的双变量比较，以及人均烟草零售商和电子烟商店的频率、比率和置信区间。
53%的烟草零售商销售电子烟。电子烟的可获得性不因无烟规定是否涵盖电子烟而有所不同。两县地区每10000人中烟草零售商和电子烟经销商的比率分别为8.29和4.40。在40所学校中，88%的学校周边1英里范围内有烟草零售商，68%的学校周边1英里范围内有电子烟经销商。
在这项探索性研究中，电子烟使用限制与商店可获得性无关。作为一种相对较新的产品，电子烟在零售店中很容易买到，且离学校很近。
