背景：二手烟暴露（SHSe）对与吸烟者生活在一起的儿童构成健康风险。大多数保护儿童免受SHSe影响的干预措施都是指导成年吸烟者。本试验确定是否教练和可替宁反馈提供给青春期前可以减少他们的SHSe.Methods：201主要是低收入家庭与居民吸烟者和8至13岁的儿童谁是暴露于两个或更多的香烟每天或有尿可替宁浓度>= 2.0 ng/mL的随机对照或SHSe减少教练组。在超过5个月的8次家庭会议期间，教练向儿童展示了可替宁测定结果的图形图表作为表现反馈，并为可替宁减少提供了不同的赞扬和激励。广义估计方程被用来确定随时间的差异变化SHSe group.Results：为基线后测试期间，教练组有一个更大的下降，尿可替宁浓度（P = 0.039）和报告的儿童SHSe在每天暴露的香烟数量（儿童报告，P = 0.003;家长报告，P = 0.078）。后测到12个月的后续行动，没有组或组的时间差，两组返回到baseline.Conclusions：教练青春期前可以减少他们的SHSe，虽然减少可能不会持续没有持续的咨询，反馈和激励。与指导成人减少儿童SHSe的干预措施不同，增加儿童避免SHSe的计划有可能在儿童暴露的所有环境中减少SHSe，而不需要改变成人吸烟行为。胸部2011; 140（3）：681-689
Background: Secondhand smoke exposure (SHSe) poses health risks to children living with smokers. Most interventions to protect children from SHSe have coached adult smokers. This trial determined whether coaching and cotinine feedback provided to preteens can reduce their SHSe.Methods: Two hundred one predominantly low-income families with a resident smoker and a child aged 8 to 13 years who was exposed to two or more cigarettes per day or had a urine cotinine concentration >= 2.0 ng/mL were randomized to control or SHSe reduction coaching groups. During eight in-home sessions over 5 months, coaches presented to the child graphic charts of cotinine assay results as performance feedback and provided differential praise and incentives for cotinine reductions. Generalized estimating equations were used to determine the differential change in SHSe over time by group.Results: For the baseline to posttest period, the coaching group had a greater decrease in both urine cotinine concentration (P = .039) and reported child SHSe in the number of cigarettes exposed per day (child report, P = .003; parent report, P = .078). For posttest to month 12 follow-up, no group or group by time differences were obtained, and both groups returned toward baseline.Conclusions: Coaching preteens can reduce their SHSe, although reductions may not be sustained without ongoing counseling, feedback, and incentives. Unlike interventions that coach adults to reduce child SHSe, programs that increase child avoidance of SHSe have the potential to reduce SHSe in all settings in which the child is exposed, without requiring a change in adult smoking behavior.
