Previous research shows the associations between secondhand smoke exposure and health consequences among youth, but less is known about its effect on academic performance. This study examines a dose-response relationship between secondhand smoke exposure and subsequent academic performance among U.S. youth.
Data were from a nationally representative sample of youth non-tobacco users (aged 12-16 years) in Wave 2 (2014-2015) who completed Wave 3 (2015-2016) of the Population Assessment of Tobacco and Health Study (n=9,020). Past-7-day number of hours exposed to secondhand smoke at Wave 2 and academic performance at Wave 3 (1=Mostly As to 9=Mostly Fs) were assessed. Weighted multivariable linear regression models were used to examine the association between hours of self-reported secondhand smoke exposure at Wave 2 and academic performance at Wave 3 (1=Mostly Fs, 9=Mostly As), adjusting for covariates including sociodemographics, prior academic performance, internalizing and externalizing problems, and substance use problems. Analyses were conducted in 2019.
More than 30% of U.S. youth non-tobacco users were exposed to secondhand smoke in the past 7 days. Compared with unexposed youth at Wave 2, those who were exposed for 1-9 hours had poorer academic performance at Wave 3 (adjusted regression coefficient= -0.11, 95% CI= -0.18, -0.04), and those who were exposed for ≥10 hours at Wave 2 had even poorer academic performance (adjusted regression coefficient = -0.31, 95% CI= -0.45, -0.18).
A dose-response relationship was observed between secondhand smoke exposure and academic performance among U.S. youth. Reducing youth secondhand smoke exposure may promote academic performance and subsequent educational attainment.
先前的研究表明，二手烟暴露与青少年健康后果之间存在关联，但对于其对学业成绩的影响知之甚少。本研究检验了美国青少年二手烟暴露与后续学业成绩之间的剂量-反应关系。
数据来自全国代表性的青少年非烟草使用者样本（年龄为 12-16 岁），他们在第 2 波（2014-2015 年）完成了第 3 波（2015-2016 年）的人口烟草与健康评估研究（n=9020）。第 2 波评估过去 7 天内暴露于二手烟的小时数，第 3 波评估学业成绩（1=大多数为 Fs，9=大多数为 As）。使用加权多变量线性回归模型，在调整了社会人口统计学、先前的学业成绩、内化和外化问题以及物质使用问题等因素后，研究了第 2 波自我报告的二手烟暴露小时数与第 3 波学业成绩之间的关联（1=大多数为 Fs，9=大多数为 As）。分析于 2019 年进行。
超过 30%的美国青少年非烟草使用者在过去 7 天内暴露于二手烟。与第 2 波未暴露的青少年相比，暴露 1-9 小时的青少年在第 3 波的学业成绩较差（调整后的回归系数=-0.11，95%CI=-0.18，-0.04），而第 2 波暴露 10 小时以上的青少年的学业成绩更差（调整后的回归系数=-0.31，95%CI=-0.45，-0.18）。
美国青少年二手烟暴露与学业成绩之间存在剂量-反应关系。减少青少年二手烟暴露可能会促进学业成绩和随后的教育程度。
