The home is the primary source of children's exposure to secondhand smoke. This study investigated the status and influencing factors of child exposure to secondhand smoke at home when people smoke in the household.
Participants with at least one child living in their household from 10 communities in Chongqing were recruited and provided a self-administered questionnaire using a multistage proportional random sampling design from June to August 2021. The chi-squared test and binary logistic regression analyses were used to identify influencing factors.
The questionnaire completed by 1345 families showed that 631 (46.9%) families lived with smokers in their household, and 509 (80.7%) of those families reported that smoking occurred within the home while the children were present. Binary logistic regression analyses demonstrated that the time between waking up and household smokers having the first cigarette of the day (OR=0.44; 95% CI: 0.22-0.85), changes to smoking habits and behaviors within the last six months (OR=1.76; 95% CI: 1.06-2.90), attitudes towards tobacco control in the household (OR=2.91; 95% CI: 1.72-4.92), self-efficacy in maintaining a smoke-free home (OR=2.27; 95% CI: 1.36-3.79), having rules to maintain a smoke-free home (OR=3.25; 95% CI: 1.68-6.29), and the status of providing cigarettes to guests at home (OR=11.0; 95% CI: 1.33-90.8) were associated with exposure to SHS.
Education focusing on the impact of smoking on children's health should be encouraged. Smoke-free homes should be established, and smoking restrictions in the household should be enacted. Therefore, information about the available tobacco-control services should be given to family members and be used properly. It is an effective way to decrease the risk of at-home exposure to SHS for children, to overcome any obstacles in tobacco control.
家庭是儿童接触二手烟的主要来源。本研究调查了在家中有家庭成员吸烟时儿童在家接触二手烟的状况及影响因素。
采用多阶段比例随机抽样设计，于2021年6月至8月招募了来自重庆10个社区、家中至少有一名儿童的参与者，并提供了一份自填式问卷。采用卡方检验和二元逻辑回归分析来确定影响因素。
1345个家庭完成的问卷显示，631个（46.9%）家庭中有吸烟者，其中509个（80.7%）家庭报告在孩子在家时家中有人吸烟。二元逻辑回归分析表明，起床至家中吸烟者吸当日第一支烟的时间间隔（比值比[OR]=0.44；95%置信区间[CI]：0.22 - 0.85）、过去六个月吸烟习惯和行为的改变（OR=1.76；95% CI：1.06 - 2.90）、家庭对控烟的态度（OR=2.91；95% CI：1.72 - 4.92）、维持无烟家庭的自我效能感（OR=2.27；95% CI：1.36 - 3.79）、有维持无烟家庭的规则（OR=3.25；95% CI：1.68 - 6.29）以及在家中向客人提供香烟的情况（OR=11.0；95% CI：1.33 - 90.8）与接触二手烟有关。
应鼓励开展关注吸烟对儿童健康影响的教育。应建立无烟家庭，并制定家庭内的吸烟限制规定。因此，应向家庭成员提供有关现有控烟服务的信息并妥善利用。这是降低儿童在家接触二手烟风险、克服控烟中任何障碍的有效途径。
