To examine the association between demographic and smoking behavior variables and the likelihood of acquiring cigarettes through noncommercial sources. The Robert Wood Johnson Foundation's 1996 National Study of Tobacco Price Sensitivity, Behavior, and Attitudes among Teenagers and Young Adults was the data source in this analysis. Respondents were high school students (grades 9 through 12) ages 13 to 19 years. The sample sizes, respondent selection procedures, and weighting procedures were designed to develop national estimates of adolescent smoking behaviors and attitudes. The questionnaire, modeled on previous surveys and input from leading tobacco control experts, was self-administered. Logistic regression was used to model the independent effects of each variable on the outcome while controlling for the influence of all other variables in the model. An inverse relationship was found between age and the likelihood of acquiring cigarettes through noncommercial sources. Females were 58% more likely to acquire cigarettes through noncommercial sources than were males. There were no differences among adolescents of different racial/ethnic groups in acquisition through noncommercial sources. Those who believed that cigarettes were difficult to acquire were more likely to obtain cigarettes by noncommercial means. Although point-of-sale restrictions have been a focal point of tobacco control legislation, these data suggest that younger smokers and those who view commercial purchase to be difficult are not using commercial sources. Therefore, more comprehensive approaches to limiting access may be required to address all sources of adolescents' acquisition. The proliferation of point-of-sale restrictions may have contributed to increases in noncommercial acquisition by creating the impression that cigarettes were more difficult to purchase. This reinforces the need for educational programs, interventions, and policies that more effectively target noncommercial sources of cigarettes.
研究人口统计学和吸烟行为变量与通过非商业渠道获取香烟可能性之间的关联。罗伯特·伍德·约翰逊基金会1996年的青少年和青年烟草价格敏感性、行为及态度全国性研究是本分析的数据来源。受访者为13至19岁的高中生（9至12年级）。样本量、受访者选择程序和加权程序旨在得出青少年吸烟行为和态度的全国性估计值。问卷以先前的调查为蓝本，并参考了主要烟草控制专家的意见，由受访者自行填写。使用逻辑回归来模拟每个变量对结果的独立影响，同时控制模型中所有其他变量的影响。研究发现，年龄与通过非商业渠道获取香烟的可能性呈负相关。女性通过非商业渠道获取香烟的可能性比男性高58%。不同种族/族裔的青少年在通过非商业渠道获取香烟方面没有差异。那些认为香烟难以获取的人更有可能通过非商业手段获得香烟。尽管销售点限制一直是烟草控制立法的重点，但这些数据表明，年轻吸烟者以及那些认为通过商业渠道购买香烟困难的人并没有利用商业渠道。因此，可能需要采取更全面的方法来限制获取途径，以应对青少年获取香烟的所有来源。销售点限制的增多可能造成了香烟更难购买的印象，从而导致通过非商业渠道获取香烟的情况增加。这进一步凸显了开展教育项目、干预措施和政策的必要性，以便更有效地针对香烟的非商业来源。
