Abstract
INTRODUCTIONSecondhand smoke (SHS) exposure affects tobacco related health behaviors during adolescence and persists into adulthood. This study aimed to investigate the influence of SHS exposure on tobacco use among adolescents stratified by school and gender, and provide recommendations for controlling tobacco use in youth.METHODSThrough stratified random cluster sampling, 12278 selected students (aged 13–18 years) from schools in China were administered questionnaires. Multiple logistic regression was used to analyze whether SHS exposure would increase the smoking risk and susceptibility of adolescents.RESULTSThe prevalence of SHS exposure among the participating students was 74.8%. Adolescents exposed to SHS were at higher odds of being susceptible and currently smoking. Students with SHS exposure at both home and public places accounted for 36.6%, greatly increasing the current smoking risk and smoking susceptibility. Home SHS exposure had greater impact on the current tobacco use of boys (OR=2.13; 95% CI: 1.50–3.03) and junior school students (OR=4.67; 95% CI: 2.41–9.06). Exposure from public places increased the risk of current smoking in boys (OR=4.20; 95% CI: 2.31–7.65) and smoking susceptibility of vocational school students (OR=1.51; 95% CI: 1.07–2.15). Students with highlevel exposure to SHS had 2.25 times higher odds of e-cigarette use.CONCLUSIONSThe prevalence of SHS exposure is still high among adolescents in China and is associated with increased risk for tobacco use regardless of gender and school level. Effective smoke-free strategies should be developed and strictly implemented. Boys and junior school students constitute vulnerable populations exposed to SHS at home.

Secondhand smoke (SHS) exposure affects tobacco related health behaviors during adolescence and persists into adulthood
With the high prevalence of SHS exposure and harmful role it plays in tobacco related behaviors in adolescents, the current study aimed to investigate the relationship between SHS exposure and tobacco use behaviors stratified by sex and school among a representative sample of adolescents in Shanghai, China
The proportion of junior high school students, senior high school students and vocational school students was 61.99%, 23.67% and 14.34%, respectively, and this was similar to the composition of students in Shanghai
Summary
Secondhand smoke (SHS) exposure affects tobacco related health behaviors during adolescence and persists into adulthood. Tobacco use and related behaviors, including secondhand smoke (SHS) exposure, smoking susceptibility, and exposure to tobacco advertising, harm health and impose a heavy economic burden on society[1,2,3]. Smoking susceptibility precedes smoking behavior and is defined as not taking a firm decision against cigarette smoking[4] It acts as a predictor of smoking experimentation and smoking status, with adolescents less likely to respond to tobacco prevention programs[5]. The prevalence of smoking among junior high school students in 2019 was lower than that in 2014 (6.9%)[10], which might prove tobacco control efforts effective, but this rate was still high
