被动吸烟对儿童免疫功能的影响

目的研究被动吸烟对儿童免疫功能的影响.方法于2002-2004年对广州市某小学135名10～11岁儿童的家庭成员吸烟情况及儿童因病缺勤状况进行问卷调查,并对其中50名儿童进行血清IgE和IL-8浓度的检测.结果被动吸烟(n=30)儿童的血清IgE浓度高于非被动吸烟组(n=20),而其IL-8浓度低于非被动吸烟组(P均＜0.05).被动吸烟儿童(n=67)因病缺勤率高于非被动吸烟儿童(n=68),差异有统计学意义(P＜0.05),且多为呼吸系统炎症.结论被动吸烟对儿童的先天性和获得性免疫功能均有不良的影响,应采取有效措施减少儿童被动吸烟的暴露.

Influence of Passive Smoking on Immune Function of Children

Objective To know the influence of passive smoking on children's immune function. Methods The smoking state of children's family members and the illness-induced absence state of 135 children aged 10-11 years were investigated with questionnaire, and the concentrations of immunoglobin E (IgE) and interleukin 8 (IL-8) in serum of children were examined. Results The concentrations of IgE in serum of the children exposed to passive smoking(n=30) were significantly higher than those of the control group(n=20), while the concentrations of IL-8 were significantly lower(both P<0.05). The rate of illness-induced absence of the children exposed to passive smoking(n=67) was significantly higher compared with the control group (n=68), P<0.05, and most of the illnesses were the respiratory system inflammation. Conclusion Passive smoking can influence the children's innate and acquired immune function.
