The objective of this study was to assess tobacco use, secondhand smoke exposure, knowledge of health risks, and smoking predictors among dental students attending King Abdulaziz University, Jeddah, Saudi Arabia.
A cross-sectional study was conducted and 420 dental students were invited to participate. Binary logistic regression analyses assessed the predictors of smoking.
A total of 336 dental students completed the questionnaires with 25% reporting current or previous tobacco use and 96% reporting secondhand smoke exposure. Nearly half of all smokers initiated smoking during the dental program. The logistic regression results revealed that being a male (OR = 7.1, p < .0001; 95%CI = 3.7-13.4) and having a smoker in the family (OR = 2.6, p = .005; 95%CI = 1.3-5.0) increased the likelihood of smoking. In contrast, knowledge of health risks decreased the likelihood of smoking (OR = 0.90, p = .014; 95%CI = 0.82-0.98).
Despite possessing knowledge about the health risks of smoking, high numbers of dental students continue to smoke and were exposed to secondhand smoke. Sex and family influence were the main pro-smoking risk factors, whereas increased knowledge of health risks was a protective factor. Tobacco control programs to reduce and/or prevent tobacco use among future dentists are needed.
本研究旨在评估沙特阿拉伯吉达阿卜杜勒阿齐兹国王大学牙科专业学生的烟草使用情况、二手烟暴露情况、健康风险知识以及吸烟预测因素。
开展了一项横断面研究，邀请420名牙科专业学生参与。二元逻辑回归分析评估了吸烟的预测因素。
共有336名牙科专业学生完成了问卷调查，25%的学生报告目前或曾经使用烟草，96%的学生报告有二手烟暴露。几乎一半的吸烟者是在牙科学习期间开始吸烟的。逻辑回归结果显示，男性（比值比=7.1，p<0.0001；95%置信区间=3.7-13.4）以及家中有吸烟者（比值比=2.6，p=0.005；95%置信区间=1.3-5.0）会增加吸烟的可能性。相比之下，对健康风险的了解会降低吸烟的可能性（比值比=0.90，p=0.014；95%置信区间=0.82-0.98）。
尽管牙科专业学生了解吸烟对健康的风险，但仍有大量学生继续吸烟并暴露于二手烟环境中。性别和家庭影响是主要的促烟风险因素，而对健康风险了解的增加是一个保护因素。需要实施烟草控制项目，以减少和/或预防未来牙医中的烟草使用。
