Few studies have reported on the prevalence of smokeless tobacco use among young children in Canada, although research conducted in the United States indicates a rising trend in smokeless tobacco use among school-aged children. We report on rates of smokeless tobacco experimentation and current use and its relationship to cigarette smoking in a large sample of students followed from Grade 6 through Grade 8 in Calgary, Canada. The rates of smokeless tobacco experimentation and use reported are low in comparison to the corresponding prevalence reported in the American findings. In accordance with the American findings, however, both experimentation and current use of smokeless tobacco were more prevalent among males. Also, a high correspondence between smokeless tobacco and cigarette use was observed.
很少有研究报告加拿大幼儿中无烟烟草的使用情况，不过美国开展的研究表明学龄儿童中无烟烟草的使用呈上升趋势。我们报告了加拿大卡尔加里一大群从六年级到八年级的学生中无烟烟草尝试和当前使用的比率及其与吸烟的关系。与美国研究结果报告的相应患病率相比，报告的无烟烟草尝试和使用率较低。然而，与美国研究结果一致的是，无烟烟草的尝试和当前使用在男性中更为普遍。此外，还观察到无烟烟草使用和吸烟之间有高度的相关性。
