Smoke-free zone policies in school settings have been widely implemented; however, evidence regarding their impact on smoking-related attitudes and secondhand smoke (SHS) exposure remains limited. This study aimed to examine the association between a smoke-free zone policy implemented along school commuting routes and attitudes toward smoking and SHS exposure among elementary school students, their parents, and school staff in Seoul, South Korea.
A cross-sectional study was conducted. Participants were 210 students, 272 parents, and 137 school staff from the five schools randomly selected according to the criteria of regional deprivation index and prevalence of designated smoke-free zones from all the 25 districts of Seoul, South Korea. "Attitudes toward smoking" and "exposure to SHS" were the outcome variables, and the "presence of a smoke-free zone along the school commuting route" was the predictor variable. All variables were assessed using self-reported questionnaires. Data were collected between November 2020 and December 2020. The multiple logistic regression analysis was performed to test main hypotheses.
Students and school staff in schools with designated smoke-free zones along school commuting routes were significantly less likely to be exposed to SHS along those routes, compared to their counterparts without such zones (odds ratio [OR] = 0.29; 95% confidence interval [CI], 0.098-0.853; p =0.025 for students; OR = 0.09; 95% CI, 0.008-0.939; p =0.044 for school staff). However, the presence of smoke-free zones along school commuting routes was not significantly associated with attitudes toward smoking among students, parents, or school staff.
Designation of smoke-free zones along school commuting routes may be effective in reducing exposure to SHS among students and school staff. The active and consistent enforcement of smoke-free policies within school settings may play a critical role in further reducing SHS exposure among children and related stakeholders.
学校场所的无烟区政策已得到广泛实施；然而，关于其对吸烟相关态度和二手烟（SHS）暴露影响的证据仍然有限。本研究旨在探讨韩国首尔沿学校通勤路线实施的无烟区政策与小学生、其家长及学校工作人员对吸烟的态度和二手烟暴露之间的关联。
开展了一项横断面研究。参与者为来自韩国首尔25个区中根据区域贫困指数和指定无烟区患病率标准随机选取的5所学校的210名学生、272名家长和137名学校工作人员。“对吸烟的态度”和“二手烟暴露”为结果变量，“学校通勤路线有无无烟区”为预测变量。所有变量均通过自填问卷进行评估。数据于2020年11月至2020年12月收集。进行多因素logistic回归分析以检验主要假设。
与没有此类区域的学生和学校工作人员相比，沿学校通勤路线设有指定无烟区的学校的学生和学校工作人员在这些路线上接触二手烟的可能性显著降低（优势比[OR]=0.29；95%置信区间[CI]，0.098 - 0.853；学生p = 0.025；OR = 0.09；95% CI，0.008 - 0.939；学校工作人员p = 0.044）。然而，学校通勤路线有无无烟区与学生、家长或学校工作人员对吸烟的态度无显著关联。
沿学校通勤路线指定无烟区可能有效减少学生和学校工作人员的二手烟暴露。在学校场所积极且持续地执行无烟政策可能在进一步减少儿童及相关利益攸关方的二手烟暴露方面发挥关键作用。
