Objectives: This study evaluated willingness to accept secondhand smoke (SHS) exposure among male dental students and assessed its determinants.
Methods: A cross sectional survey using a sample of male dental students was conducted. An anonymous self-administered paper and pencil questionnaire was used, which included questions about the main source of exposure, awareness of SHS exposure hazards, and willingness to accept SHS exposure. We used a willingness to accept SHS exposure scale and evaluated its determinants. Results were analyzed using multiple linear regression analysis.
Results: Overall, 143 (a response rate of 88%) completed the questionnaires. Results revealed 96% of dental students were exposed to secondhand smoking. In addition, they reported high exposures in public places (76%), at the University (76%), and in friend’s house (33%). However, only 18% reported exposure at home. Mean value for the willingness to accept SHS exposure scale (Cronbach’s Alpha =0.85) was 46±17. The multivariate model showed a direct relationship of increased willingness to accept SHS exposure with being a smoker (b = 17.3, 95% confidence interval (CI) = 12.4 to 22.3, p < .0001), and with being exposed to SHS at home (b = 7.4, 95% confidence interval (CI) = 1.2 to 13.6, p = 0.02).
Conclusions: A remarkable percentage of dental students were exposed to secondhand smoking. At home exposure resulted in increased willingness to accept SHS exposure in general. Awareness about health impacts of SHS exposure needs to be increased among dental students.
