The purpose of this study was to determine whether there is a growing inequity in tobacco use, susceptibility to future smoking, and quit attempts among Off-Reserve Aboriginal (ORA) youth in Canada relative to Non-Aboriginal youth. Current smoking, susceptibility to future smoking and quit attempts were examined among a nationally representative sample of ORA and Non-Aboriginal Canadian youth. Data are from cross-sectional surveys of 88,661 respondents in Grades 6 to 9 across the 2004, 2006 and 2008 survey waves of the Youth Smoking Survey (YSS). At each wave, ORA youth were more likely to be current smokers (overall OR = 3.91, 95% CI 3.47 to 4.41), to be susceptible to future smoking (overall OR = 1.37, 95% CI 1.27 to 1.48), and less likely to have ever made a quit attempt compared to Non-Aboriginal youth (overall OR = 0.74, 95% CI 0.57 to 0.96). Although susceptibility to future smoking declined for Non-Aboriginal youth, the prevalence of susceptibility remained stable among ORA youth. The percentage of ORA youth reporting making a quit attempt increased, however, current smoking rates among ORA youth did not decline. These findings suggest that the disparity in susceptibility to future tobacco use among ORA and Non-Aboriginal youth has increased over time. Despite increased rates of quit attempts, current smoking rates remain significantly higher among ORA youth. Tobacco control programs for Aboriginal youth should be a public health priority.
本研究旨在确定在加拿大，与非原住民青年相比，原住民青年（ORA）中烟草使用、未来吸烟易感性和戒烟尝试是否存在日益扩大的不平等现象。本研究对全国代表性的 ORA 和非原住民加拿大青年样本进行了当前吸烟、未来吸烟易感性和戒烟尝试的调查。数据来自于青年吸烟调查（YSS）2004 年、2006 年和 2008 年调查波次中，6 年级至 9 年级的 88661 名受访者的横断面调查。在每个波次中，ORA 青年更有可能成为当前吸烟者（总体比值比[OR] = 3.91，95%置信区间[CI] 3.47 至 4.41），更有可能具有未来吸烟易感性（总体 OR = 1.37，95% CI 1.27 至 1.48），且与非原住民青年相比，更少进行戒烟尝试（总体 OR = 0.74，95% CI 0.57 至 0.96）。尽管非原住民青年的未来吸烟易感性有所下降，但 ORA 青年的易感性患病率保持稳定。然而，报告进行戒烟尝试的 ORA 青年比例增加，ORA 青年的当前吸烟率并未下降。这些发现表明，在 ORA 和非原住民青年中，未来烟草使用的易感性差距随着时间的推移而增加。尽管戒烟尝试的比率增加，但 ORA 青年的当前吸烟率仍然明显更高。针对原住民青年的烟草控制计划应成为公共卫生的重点。
