The prevalence of smoking is higher in Latvia than in most EU countries. This study aimed to determine the level of knowledge of dental students in Latvia about the effects of smoking on oral health and their attitudes toward smoking and its cessation.
A cross-sectional survey among all the dental students in Latvia was conducted in 2011. Students at the Riga Stradins University were asked to participate in this anonymous, voluntary survey. The questionnaire included items concerned with the students' own smoking habits, their knowledge of smoking as an addiction and its health effects and their attitudes towards its prevention and cessation in a dental setting. The response rate was 87% (173/200). The Chi-square test and logistic regression were used for the statistical analyses.
About one quarter of the students (24%) were daily or occasional smokers and almost half of the male students (46%) had smoked at least 100-times in their lifetime. The students revealed a lack of knowledge about the addictive nature of smoking, in that about half of the students did not consider smoking physically or socially addictive. About one fifth (21.4%) didn't consider environmental tobacco smoke (ETS) harmful to one's health. Although the students' awareness of smoking improved during their studies, the most significant factor related to their knowledge was their own smoking history (OR=2.7; p=0.021).
Smoking was frequent among undergraduate dental students and they lacked knowledge of its addictiveness. More emphasis ought to be placed on education with regard to smoking and on cessation services.
拉脱维亚的吸烟率高于大多数欧盟国家。本研究旨在确定拉脱维亚牙科学生对吸烟对口腔健康影响的了解程度，以及他们对吸烟及其戒烟的态度。
2011年对拉脱维亚所有牙科学生进行了一项横断面调查。里加斯特拉迪纳斯大学的学生被要求参与这项匿名的自愿调查。问卷包括与学生自身吸烟习惯、对吸烟成瘾及其健康影响的了解，以及他们在牙科环境中对吸烟预防和戒烟的态度有关的项目。回复率为87%（173/200）。采用卡方检验和逻辑回归进行统计分析。
约四分之一的学生（24%）为每日吸烟者或偶尔吸烟者，近一半的男学生（46%）一生中至少吸烟100次。学生们对吸烟成瘾性缺乏了解，约一半的学生不认为吸烟在生理上或社交上会上瘾。约五分之一（21.4%）的学生不认为环境烟草烟雾（ETS）对健康有害。尽管学生们在学习期间对吸烟的认识有所提高，但与他们的知识最相关的因素是他们自己的吸烟史（OR=2.7；p=0.021）。
本科牙科学生中吸烟现象较为普遍，他们对吸烟成瘾性缺乏了解。应该更加重视吸烟教育和戒烟服务。
