To assess the impact of different smoking behaviors of caregivers on environmental tobacco smoke (ETS) exposure in children aged 5-6 years in Changsha, China.
We conducted a cross-sectional, random digit-dial telephone survey of caregivers (n = 543) between August and October 2013. Caregivers' smoking behaviors were collected by a questionnaire. Exposure assessment was based upon determination of urinary cotinine levels in children employing gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS).
In children not living with a smoker, children living with one smoker, and children living with more than one smoker at home, median urinary cotinine concentrations (ng/mL) were 0.72, 2.97, and 4.46, respectively. For children living with one smoker, median urinary cotinine levels of children exposed to ETS were associated with caregiver smoking behaviors, i.e., if a caregiver consumed more cigarettes (>20 compared with ≤10; 7.73 versus 2.29 ng/mL, respectively).
The magnitude of ETS exposure in children is correlated with the smoking behaviors of the caregiver. Counseling for smoking cessation and educational interventions are needed urgently for smoking caregivers to increase their awareness about ETS exposure and to encourage smoking cessation at home or to take precautions to protect children's health.
评估中国长沙5 - 6岁儿童的照料者不同吸烟行为对儿童环境烟草烟雾（ETS）暴露的影响。
2013年8月至10月，我们对照料者（n = 543）进行了一项横断面随机数字拨号电话调查。通过问卷收集照料者的吸烟行为。采用气相色谱 - 三重四极杆质谱法（GC - MS/MS）测定儿童尿可替宁水平进行暴露评估。
在不与吸烟者同住的儿童、与一名吸烟者同住的儿童以及家中与多名吸烟者同住的儿童中，尿可替宁中位数浓度（ng/mL）分别为0.72、2.97和4.46。对于与一名吸烟者同住的儿童，暴露于ETS的儿童尿可替宁中位数水平与照料者吸烟行为相关，即如果照料者吸烟量较多（>20支对比≤10支；分别为7.73与2.29 ng/mL）。
儿童ETS暴露程度与照料者吸烟行为相关。迫切需要对吸烟的照料者进行戒烟咨询和教育干预，以提高他们对ETS暴露的认识，并鼓励在家中戒烟或采取预防措施保护儿童健康。
