Investigation on present situation of children’s exposure to passive smoking and evaluation on health propagation

ObjectiveTo know the present situation of the children's exposure to passive smoking and the effect of the relative health propagation.MethodThe smoking state of children's family members and its effects on 791 chidren aged 10～11 years were investigated with questionnaire,among whom 312 children's family members were chosen randomly to take the relative health propagation,and the effect of the propagation was evaluated.Results(1)The rate of chidren's exposure to passive smoking was 46.5%,which mainly came from fathers'smoking,up to 76.63%.(2)In the latest term,the incidence of bronchitis and the infection on the upper air tube of the children exposed to passive smoking were significantly higher than those of the control group(P<0.05),while there were no significant difference between the incidence of pneumonia and asthma of the two groups(P>0.05).And there were no significant difference between the statue and the weight of the two groups(P>0.05).(3)After the health propagation of the adverse effects of passive smoking,the rate of passive smoking reduced by 5.1%,and 68.4% smokers would like to give up smoking for the children's health,while 11.3% smokers would not.The smoking quantities had no significant changes.ConclusionThe present situation of the childresn's exposure to passive smoking is still serious,and to some extent,the health propagation about the children's health is useful to the smoking control.
