Understanding the different ways underage youth access tobacco is required in order to develop more effective tobacco access restrictions. The purpose of this study was to examine characteristics that predict whether underage smoking youth buy their own cigarettes, buy their cigarettes from friends, or get someone else to buy their cigarettes.
Logistic regression analyses were used to examine the predictors of three different tobacco access behaviours among 737 occasional smoking and 2,050 regular smoking youth.
Most smoking youth were asked their age less than half of the time when trying to buy cigarettes. Occasional smokers usually buy their cigarettes from a friend (59.5%) and the majority of regular smokers usually buy their own cigarettes (59.8%). Occasional smokers were less likely to buy their own cigarettes (OR 0.85) and more likely to ask someone else to buy their cigarettes (OR 1.24) the more frequently they were asked their age on purchase attempts. Regular smokers were also less likely to buy their own cigarettes (OR 0.70) and more likely to buy their cigarettes from someone else (OR 1.51) or a friend (OR 1.18) the more frequently they were asked their age on purchase attempts.
Point-of-sale restrictions are insufficient to prevent youth from acquiring cigarettes because youth commonly access cigarettes from social sources. A more comprehensive approach for restricting access is required that targets both underage youth and individuals who purchase tobacco for underage youth.
为了制定更有效的烟草获取限制措施，需要了解未成年青少年获取烟草的不同方式。本研究的目的是调查能够预测未成年吸烟青少年是自己购买香烟、从朋友处购买香烟还是让他人为其购买香烟的特征。
采用逻辑回归分析来研究737名偶尔吸烟和2050名经常吸烟的青少年中三种不同烟草获取行为的预测因素。
大多数吸烟青少年在尝试购买香烟时，被询问年龄的次数不到一半。偶尔吸烟者通常从朋友处购买香烟（59.5%），而大多数经常吸烟者通常自己购买香烟（59.8%）。购买香烟时，被询问年龄的次数越多，偶尔吸烟者自己购买香烟的可能性越小（比值比0.85），让他人为其购买香烟的可能性越大（比值比1.24）。购买香烟时，被询问年龄的次数越多，经常吸烟者自己购买香烟的可能性也越小（比值比0.70），从他人（比值比1.51）或朋友处（比值比1.18）购买香烟的可能性越大。
销售点限制不足以阻止青少年获取香烟，因为青少年通常从社交渠道获取香烟。需要一种更全面的方法来限制获取，该方法既要针对未成年青少年，也要针对为未成年青少年购买烟草的个人。
