It is well documented that, similar to active smokers, passive smokers are also at an increased risk of developing non-communicable diseases, and it could impose high financial costs on the healthcare system. This study aimed to evaluate the trend of passive smoking and related determinants during the three phases of a school-based surveillance program.
This is a secondary study using the national data obtained from three phases of the surveillance program entitled The Childhood and Adolescence Surveillance and Prevention of Adult Noncommunicable Disease (CASPIAN) study, conducted from 2008 to 2014 on Iranian children and adolescents living in urban and rural areas of 30 provinces in Iran. Participants were selected by cluster multistage sampling method.
Overall, the study participants consisted of 33,288 students (50.5% boys) with a mean (± SD) age of 12.8 ± 3.2 years. The passive smoking rate was significantly increased from 35.6% in 2008 to 43.2% in 2015 among children and adolescents. According to the multivariate logistic regression, father's university education, mother's employment, life satisfaction, and socioeconomic status had a protective role regarding second-hand smoke exposure. In contrast, the father's self-employment had a positive role in increasing the rate of passive smoking.
Considering the increasing trend of passive smoking and its considerable adverse health effects, it is necessary to implement large-scale public interventions to reduce the rate and hazards of exposure to tobacco smoke.
有充分的文献记载表明，与主动吸烟者类似，被动吸烟者罹患非传染性疾病的风险也会增加，而且这会给医疗保健系统带来高昂的经济成本。本研究旨在评估一个基于学校的监测项目的三个阶段中被动吸烟及其相关决定因素的趋势。
这是一项二次研究，使用了从 2008 年至 2014 年在伊朗城乡地区 30 个省份开展的题为《儿童和青少年监测与预防成人非传染性疾病》（CASPIAN）研究的全国数据。采用整群多级抽样方法选择参与者。
总体而言，研究参与者包括 33288 名学生（50.5%为男生），平均（±SD）年龄为 12.8±3.2 岁。儿童和青少年的被动吸烟率从 2008 年的 35.6%显著上升到 2015 年的 43.2%。根据多变量逻辑回归分析，父亲的大学教育、母亲的就业、生活满意度和社会经济地位对二手烟暴露具有保护作用。相反，父亲的自营职业对增加被动吸烟率有积极作用。
鉴于被动吸烟呈上升趋势及其对健康的不良影响，有必要实施大规模的公众干预措施，以降低吸烟率和减少暴露于烟草烟雾的危害。
