ABSTRACT

ABSTRACT Objective: This study evaluated the frequency and risk factors of secondhand tobacco smoke (SHS) among high school students in Taiwan. Methods: Data from the General Tobacco Hazard Proficiency Test were investigated for 4,671 students during 2017. The SHS exposure was divided into four groups with the intensity of exposure. The chi-square test and ordinal logistic regression were used for inferential statistical analysis. Results: 9.9% of students are exposed to SHS every day; the highest exposure rate was found in people living in urban areas (≥100,000 people per kilometer), male and family members smoking or with betel chewing habits. Boys were less likely exposed to SHS than female students (aOR 0.769, 95% CI 0.682 to 0.868). The areas with less than 49,999 people per kilometer have the lowest SHS exposure rate (aOR 0.713, 95% CI 0.533 to 0.954), and students with smoking or betel chewing family members proved a higher SHS exposure rate (aOR 5.332, 95% CI 4.641 to 6.126 and aOR 1.422, 95% CI 1.232 to 1.642, respectively). Conclusions: These findings not only highlight the risk factors of SHS exposure in high school students, but also show a direction for developing effective intervention programs for the prevention of SHS exposure.
