Abstract
Background
The risk of head and neck cancers (HNCs) and ear, nose, and throat (ENT) diseases due to second-hand smoke (SHS) have not been fully assessed.
Objective
To determine which ENT diseases or HNCs are associated with SHS.
Material and methods
Data from a survey of a cross-sectional sample of ENT patients (n = 1228) on SHS exposure were compared to control-subject data (n = 6598) from a Japan National Health Survey. Multivariate logistic regression and estimated odds ratios (ORs) determined whether SHS-disease associations were related to exposure location and disease occurrence.
Results
SHS was significantly associated with acute tonsillitis (OR in workplaces, 2.24 [95% CI, 1.34–3.75]; OR in restaurants, 4.24 [95% CI, 2.50–7.19]; OR in leisure places, 4.72 [95% CI, 2.93–7.62]); recurrent tonsillitis (OR in restaurants, 4.24 [95% CI, 2.52–7.13]; OR in leisure places, 5.29 [95% CI, 3.31–8.46]); facial palsy (OR in home, 2.18 [95% CI, 1.25–3.81]; OR in leisure places, 3.41 [95% CI, 1.97–5.89]); hypopharyngeal cancer (OR in home, 2.51 [95% CI, 1.18–5.36]; OR in workplaces, 2.53 [95% CI, 1.24–5.15]); and laryngeal cancer (OR in home, 2.44 [95% CI, 1.04–5.68]; OR in leisure places, 2.25 [95% CI, 1.00–5.07]).
Conclusions and significance
SHS may contribute to HNCs and ENT diseases, suggesting that merely being in the presence of smokers could increase the risk of head and neck morbidities.

背景:二手烟 (SHS)对头颈癌 (HNC) 和耳鼻喉 (ENT) 疾病的风险尚未得到充分评估。
目的:确定哪些ENT病或 HNC 与 SHS 相关。
材料和方法:将对暴露于二手烟的耳鼻喉科患者(n =1228)横断面样本调查的数据与日本国家健康调查的对照受试者数据 (n = 6598) 进行比较。多变量逻辑回归和估计比值比 (OR) 确定 SHS 与疾病的关系是否与暴露位置和疾病发生有关。
结果:SHS 与急性扁桃体炎显著相关(工作场所的 OR, 2.24 [95% CI, 1.34–3.75];餐馆的OR, 4.24 [95% CI, 2.50–7.19];休闲场所的OR, 4.72 [95% CI, 2.93–7.62]);复发性扁桃体炎(餐厅的 OR, 4.24 [95% CI, 2.52–7.13];休闲场所的 OR, 5.29 [95% CI, 3.31–8.46]);面瘫(居所OR, 2.18 [95% CI, 1.25-3.81];休闲场所OR, 3.41 [95% CI, 1.97–5.89]);下咽癌(居所OR, 2.51 [95% CI, 1.18-5.36];工作场所的 OR, 2.53 [95%CI, 1.24–5.15]);喉癌(居所OR, 2.44 [95% CI, 1.04–5.68];休闲场所 OR, 2.25[95% CI, 1.00–5.07])。
结论和意义:SHS 可能导致 头颈癌和耳鼻喉疾病, 表明只要有吸烟者在场, 就可能会增加头颈部疾病的风险。
