Life course exposure to passive smoke may predict health, but there are few validated measures. We tested the reliability and validity of a retrospective life course passive smoking questionnaire.
Participants from the third follow-up of the Childhood Determinants of Adult Health study (2014-2019, ages 36-49 years) retrospectively reported mother/father/other household member smoking when living at home during childhood, including duration (years) and smoking location (never/sometimes/always inside house). The severity of exposure index (SEI; sum of mother/father/other years smoked multiplied by smoking location), cumulative years of exposure (CYE; sum of mother/father/other years), and total household smokers (THS) were derived. The reliability of retrospective passive smoking reports was examined with intraclass correlation coefficients (ICCs) using household smoking reported 34 years earlier in 1985 by participants when aged 7-15 years. Construct validity was examined by correlating retrospective passive smoking with participants' smoking in adulthood and lung function in childhood and adulthood.
Among 2082 participants (mean±standard deviation [SD], 45.0±2.5 years; 55.2% females), THS ranged from 0 to 5 (mean± SD, 0.9±1.0), CYE ranged from 0 to 106 (mean±SD, 10.5±13.9), and SEI ranged from 0 to 318 (mean±SD, 24.4±36.0). Retrospective measures showed moderate agreement with total household smokers reported in childhood (ICC, 0.58 to 0.62). The retrospective measures were weakly but significantly (p<0.05) correlated with participants' smoking (r=0.13 to 0.15) and lung function (r= -0.05 to -0.06).
The retrospective passive smoking questionnaire showed reasonable reliability and validity. This measure may be useful for epidemiological studies.
一生中接触被动吸烟可能会影响健康，但目前可用的验证方法较少。本研究旨在检验回顾性生命历程被动吸烟问卷的信度和效度。
本研究参与者来自第三次“童年决定成年健康研究”随访（2014-2019 年，年龄 36-49 岁），他们回顾了童年时期家中母亲/父亲/其他家庭成员吸烟情况，包括吸烟年限（年）和吸烟地点（从不/有时/总是在室内）。由此得出暴露严重程度指数（SEI；母亲/父亲/其他吸烟者吸烟年限与吸烟地点的乘积之和）、累计吸烟年限（CYE；母亲/父亲/其他吸烟者吸烟年限之和）和家庭吸烟者总数（THS）。通过参与者在 1985 年 7-15 岁时报告的 34 年前的家庭吸烟情况，使用组内相关系数（ICC）来检验回顾性被动吸烟报告的可靠性。通过比较回顾性被动吸烟与成年后吸烟行为和儿童及成年期肺功能的相关性来检验构建效度。
在 2082 名参与者中（平均年龄±标准差为 45.0±2.5 岁，55.2%为女性），THS 范围为 0-5（平均±标准差，0.9±1.0），CYE 范围为 0-106（平均±标准差，10.5±13.9），SEI 范围为 0-318（平均±标准差，24.4±36.0）。回顾性测量与儿童时期报告的家庭吸烟者总数具有中等一致性（ICC 值为 0.58 至 0.62）。该回顾性测量与参与者的吸烟行为（r=0.13 至 0.15）和肺功能（r=-0.05 至-0.06）呈弱相关，但有统计学意义（p<0.05）。
回顾性被动吸烟问卷具有良好的信度和效度。该方法可能对流行病学研究有用。
