Long-term passive exposure to cigarette smoke has been reported to affect the health of non-smokers. This study aims to investigate the relationships among socioeconomic factors and passive smoking at home in the non-current smokers of a representative sample from a general Japanese population.
Data are from NIPPON DATA2010. Among 2,891 participants, 2,288 non-current smokers (1,763 never smokers and 525 past smokers) were analyzed in the present study. Cross-sectional analyses were performed on the relationships among socioeconomic factors and passive smoking at home (several times a week or more) in men and women separately. Socioeconomic factors were employment, length of education, marital status, and equivalent household expenditure. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a multivariable logistic regression model.
The multivariable-adjusted model showed that employed women had a higher risk of passive smoking than unemployed women (OR 1.44; 95% CI, 1.06-1.96). Women with 9 years or less of education had a higher risk of passive smoking at home than women with 13 years and more of education (OR 2.37; 95% CI, 1.49-3.78). Single women had a lower risk of passive smoking at home (OR 0.53; 95% CI, 0.37-0.77) than married women. No significant associations were observed in men.
An employed status, lower education, and being single were associated with passive smoking at home in the non-current smoking women of a representative Japanese population.
长期被动暴露于香烟烟雾已被报道会影响非吸烟者的健康。本研究旨在调查日本代表性一般人群中从不吸烟者和曾经吸烟者中社会经济因素与家中被动吸烟之间的关系。
数据来自 NIPPON DATA2010。在 2891 名参与者中，本研究分析了 2288 名从不吸烟者（1763 名从不吸烟者和 525 名曾经吸烟者）。分别对男性和女性的社会经济因素与家中（每周几次或更多）被动吸烟之间的关系进行了横断面分析。社会经济因素包括就业状况、受教育年限、婚姻状况和家庭等效支出。使用多变量逻辑回归模型计算比值比（OR）和 95%置信区间（CI）。
多变量调整模型显示，与失业女性相比，就业女性被动吸烟的风险更高（OR 1.44；95%CI，1.06-1.96）。与接受 13 年及以上教育的女性相比，接受 9 年及以下教育的女性在家中被动吸烟的风险更高（OR 2.37；95%CI，1.49-3.78）。单身女性在家中被动吸烟的风险低于已婚女性（OR 0.53；95%CI，0.37-0.77）。在男性中未观察到显著关联。
在日本代表性一般人群中从不吸烟者中，就业状况、较低的教育程度和单身状态与家中被动吸烟有关。
