背景：青年烟草的可及性很难衡量，部分原因是香烟的来源多种多样。对香烟可及性的看法评估了所有潜在来源的可用性，并被发现可以预测未来的吸烟情况。本研究探讨了从纵向study.Methods的角度来看，感知的可访问性的决定因素：数据来自第二次开发和评估的尼古丁依赖的青少年研究，一项为期4年的纵向研究，1246六年级的学生进行了长达11个人的访谈，从2002年至2006年。感知的可及性进行了评估，前瞻性地问学生是否同意或不同意的声明，这将是很容易的，我得到一个cigarette.Results：在基线，平均年龄为12岁，85%以前从未吸烟，超过21%的人认为，香烟很容易获得。在队列中，4年来感知的可及性增加。与吸烟的朋友或父母允许看R级电影的年轻人更容易感知香烟的容易获得性。在非吸烟者中，在家庭环境中感知的可及性和暴露于吸烟之间存在剂量反应关系。不吸烟者谁知道商业来源的香烟也有较高的感知accessibility.Conclusions：几个潜在的可预防的暴露于烟草在家庭和社会环境中有助于一些青年人的信心，香烟很容易获得。需要进一步的研究来确定是否修改这些因素（例如，通过减少青少年在家中接触烟草制品的方案）可能会减少人们对烟草制品的可获得性的感知。
Background: The accessibility of tobacco for youth is difficult to measure, partly because of the varied sources of cigarettes. Perceptions about the accessibility of cigarettes assesses availability from all potential sources and has been found to predict future smoking. This study examines the determinants of perceived accessibility from the perspective of a longitudinal study.Methods: Data were derived from the second Development and Assessment of Nicotine Dependence in Youth study, a 4-year longitudinal study of 1246 sixth-grade students who underwent up to 11 in-person interviews from 2002 to 2006. Perceived accessibility was assessed prospectively by asking students whether they agreed or disagreed with the statement It would be easy for me to get a cigarette.Results: At baseline, the average age was 12 years; 85% had never before smoked; more than 21% perceived that cigarettes were easy to obtain. Perceived accessibility increased over the 4 years among the cohort. Youth with friends who smoked or whose parents allowed the watching of R-rated movies were more likely to perceive easy accessibility of cigarettes. Among nonsmokers, there was a dose-response relationship between perceived accessibility and exposure to smoking in the family environment. Nonsmokers who knew commercial sources of cigarettes also had higher perceived accessibility.Conclusions: Several potentially preventable exposures to tobacco in the family and social environment contribute to confidence among some youth that cigarettes are easy to obtain. Further studies are needed to determine if modifying these factors (e.g., through programs to reduce the exposure of youth to tobacco products in the home) might reduce perceived accessibility.
