Abstract: Objective To investigate the status of household second-hand smoke (SHS) exposure among school-aged children in Guangzhou and Foshan and their self-protection behavior. Method Totally 385 school-age children in Grades 4 and above from primary schools in Guangzhou and Foshan were investigated with self-designed questionnaires. Results The surveyed results showed that the smoking attempt rate of the school-aged children was 9.2%,and the boys' smoking-attempting rate was significantly higher than that of the girls' (χ²=9.269,P=0.002).46.8% of school-aged children were living with at least 1 smoker,and 42.6% of smokers smoked almost every day.Second-hand smoke in the house could come from family members as well as guests,nearly 30% of the school-aged children were exposed to second-hand smoke from guests in one month,42.6% of the families even offered guests cigarettes.Except in houses,the exposure also took place in private cars.But most of children didn't approve of smoking and held that second-hand smoke is harmful to them.Faced with second-hand smoke exposure from family members,98.8% of school-age children took active or passive self-protective action,some had advised household smokers to quit smoking.Girls were more likely to persuade family members to give up smoking(χ²=7.161,P= 0.012).Almost 70% of smokers had positive changes after their children's persuasion and 8.8% of them had quit smoking. Conclusion The present situation of the school-age children's exposure to second-hand smoke is still serious.However,children have certain self-protection ability to passive smoking and need more gender-specific guidance.Attention should be paid to combining children's and parents' strengths to create "Smoke-Free Homes" on tobacco control in China.
