Despite the apparent decline in the popularity of roll-your-own (RYO) cigarettes over the past few decades, RYO tobacco products are widely available and used by a substantial number of adult smokers. Considering research has yet to examine the prevalence of RYO tobacco use among youth populations, this manuscript examines the prevalence of RYO tobacco use and factors associated with RYO use in a nationally representative sample of youth smokers from Canada.
This study used data collected from 3,630 current smokers in grades 9 to 12 as part of the 2008-09 Canadian Youth Smoking Survey (YSS). Descriptive analyses of the sample demographic characteristics, smoking status, cigarettes per day, weekly spending money, and frequency of marijuana use were examined by RYO tobacco ever use and RYO tobacco current use. Two logistic regression models were used to examine factors associated with RYO tobacco ever use and RYO tobacco current use.
We identified that 51.2% of current smokers were RYO ever users and 24.2% were RYO current users. The prevalence of RYO current users was highest in Atlantic Canada (40.1%) and lowest in Quebec (12.3%). RYO current users were more likely to be male (OR 1.27), to be daily smokers (OR 1.75), to use marijuana once a month or more (OR 2.74), and to smoke 11 or more cigarettes per day (OR 6.52). RYO current users were less likely to be in grade 11 (OR 0.65) or grade 12 (OR 0.40) and less likely to have between $20 to $100 (OR 0.44) or more than $100 (OR 0.45) of disposable income.
Developing a better understanding of RYO tobacco use among youth is important for advancing population-level tobacco control prevention strategies and cessation programs. We identified that RYO tobacco use is not a negligible problem among Canadian youth. Ongoing research is needed to continue monitoring the prevalence of RYO use among youth and the factors associated with its use, but to also monitor if this more affordable tobacco product is being targeted to price sensitive youth smokers.
尽管过去几十年来 Roll-Your-Own（RYO）香烟的受欢迎程度明显下降，但 RYO 烟草产品仍然广泛供应，并被大量成年吸烟者使用。考虑到目前还没有研究调查 RYO 烟草在青少年人群中的流行程度，本文研究了加拿大全国代表性青少年吸烟者群体中 RYO 烟草使用的流行程度以及与 RYO 使用相关的因素。
本研究使用了 2008-09 年加拿大青少年吸烟调查（YSS）中收集的 3630 名目前在 9 至 12 年级的吸烟者的数据。通过 RYO 烟草曾经使用和 RYO 烟草当前使用，对样本人口统计学特征、吸烟状况、每天吸烟量、每周零花钱和大麻使用频率进行了描述性分析。使用了两个逻辑回归模型来检验与 RYO 烟草曾经使用和 RYO 烟草当前使用相关的因素。
我们发现，51.2%的目前吸烟者是 RYO 曾经使用者，24.2%是 RYO 当前使用者。RYO 当前使用者的流行率在大西洋省份最高（40.1%），在魁北克省最低（12.3%）。RYO 当前使用者更可能是男性（比值比 1.27）、每日吸烟者（比值比 1.75）、每月吸食大麻一次或以上（比值比 2.74）、每天吸烟 11 支或以上（比值比 6.52）。RYO 当前使用者更不可能是 11 年级（比值比 0.65）或 12 年级（比值比 0.40），也不太可能有 20 至 100 加元（比值比 0.44）或 100 加元以上（比值比 0.45）的可支配收入。
对于推进以人群为基础的烟草控制预防策略和戒烟计划，了解青少年 RYO 烟草使用情况非常重要。我们发现，RYO 烟草在加拿大青少年中并不是一个微不足道的问题。需要进行持续的研究，以继续监测青少年中 RYO 使用的流行程度以及与使用相关的因素，但也要监测这种更经济实惠的烟草产品是否针对价格敏感的青少年吸烟者。
