| 要約: | Introduction
Thirdhand smoke is an emerging threat to global public health. There
is no research on young people's exposure to thirdhand smoke in China. This
study aims to investigate the exposure status and beliefs of thirdhand smoke
among young Chinese people and provide a reference for policy regarding
thirdhand smoke.
Methods
Data from the 2022 Chinese Resident Psychological and Behavioral Survey
were used to select young people aged 15–24 years. A total of 11781 subjects
were included in this study. Demographic information, beliefs about thirdhand
smoke, and exposure status to thirdhand smoke were investigated.
Results
Among the participants, 47.8% reported being exposed to thirdhand smoke
(males: 49.1%, females: 47.0%). Young people living in urban areas (AOR=0.84,
95% CI: 0.77–0.91, p 12000
RMB (AOR=0.81, 95% CI: 0.71–0.92, p=0.001) were less likely to be exposed to
thirdhand smoke. Young people with junior high school education or higher, and
current or former smokers, were more likely to be exposed to thirdhand smoke.
There is room for improvement in the beliefs about thirdhand smoke among
young people.
Conclusions
Thirdhand smoke exposure is an issue that should be addressed
in public health policy. Young people with low income and current or former
smokers are populations that should be mainly focused on in public education
and prevention work on thirdhand smoke.
