需要采取干预措施来保护与吸烟者生活在一起的儿童的健康。我们试点测试了一种实时干预措施，可促进家庭行为改变，从而降低二手烟 (SHS) 水平。该干预措施使用监测器和反馈系统来提供在定义的细颗粒浓度阈值下触发的即时听觉和视觉信号。实时颗粒水平的动态图也显示在计算机屏幕上。我们通过实验评估了该系统，在有吸烟者的家庭中进行了现场测试，并进行了焦点小组讨论以获取总体意见。该监测仪的实验室测试表明 SHS 灵敏度、稳定性、精度至少相当于 1 µg/m3，并且噪音低。在高达 150 µg/m3 的监测器和平均 SHS 质量浓度之间观察到线性关系 (R2 = 0.98)。焦点小组和对干预参与者的采访表明，家庭使用是可以接受和可行的。干预措施在 3 个家庭中进行了评估，基线期和干预期相结合持续 9 至 15 天。两个家庭通过打开门窗、在室外吸烟或减少吸烟来改变他们的行为。我们观察到这些家庭中二手烟水平较低的证据。其余家庭表示不愿意改变吸烟活动，并且主要吸烟区的二手烟水平没有降低，也没有出现明显的行为改变；然而，家庭成员表示愿意在户外吸烟。本研究确立了实时干预的可行性，为更大样本量的对照试验奠定了基础。视觉和听觉提示可能会促使家庭成员立即采取行动降低二手烟水平。二手烟水平的动态图表可以帮助家庭做出有关具体缓解方法的决策。
Interventions are needed to protect the health of children who live with smokers. We pilot-tested a real-time intervention for promoting behavior change in homes that reduces second hand tobacco smoke (SHS) levels. The intervention uses a monitor and feedback system to provide immediate auditory and visual signals triggered at defined thresholds of fine particle concentration. Dynamic graphs of real-time particle levels are also shown on a computer screen. We experimentally evaluated the system, field-tested it in homes with smokers, and conducted focus groups to obtain general opinions. Laboratory tests of the monitor demonstrated SHS sensitivity, stability, precision equivalent to at least 1 µg/m3, and low noise. A linear relationship (R2 = 0.98) was observed between the monitor and average SHS mass concentrations up to 150 µg/m3. Focus groups and interviews with intervention participants showed in-home use to be acceptable and feasible. The intervention was evaluated in 3 homes with combined baseline and intervention periods lasting 9 to 15 full days. Two families modified their behavior by opening windows or doors, smoking outdoors, or smoking less. We observed evidence of lower SHS levels in these homes. The remaining household voiced reluctance to changing their smoking activity and did not exhibit lower SHS levels in main smoking areas or clear behavior change; however, family members expressed receptivity to smoking outdoors. This study established the feasibility of the real-time intervention, laying the groundwork for controlled trials with larger sample sizes. Visual and auditory cues may prompt family members to take immediate action to reduce SHS levels. Dynamic graphs of SHS levels may help families make decisions about specific mitigation approaches.
