Status Of Passive Smoking Of Infant And Effectiveness Of Intervention

Objectives To investigate the status of passive smoking of infant in Tianjin andanalyze the influences of passive smoking on growth and health of children. Toreduce the amount of passive smoking through educating intervention of smokingfamilies and evaluate the effectiveness of intervention. To investigate thesituation of recognition and performance of clinical instruction about passivesmoking of infant of medical staff.Methods The conditions of 622 children in city and rural community familiesconsistent with request were general investigated. The attitudes and knowledgescore of parent and the influence of passive smoking on body height, weight andmorbidity of children. 360 passive smoking families were divided intointervention group and control group. All the families were before interventionincluding attitude and knowledge score of parent, evaluating of family smokingconditions and health status of children. were distributed to the intervention and control groups. And thewords "Smoking is harmful to health" were printed on the cover of handbook.Otherwise, the health instruction handbook were distributed to the intervention groups. Once a month offace to face instruction and consultion were given to the intervention groupssupervising and urging the parent to make a no smoking environment, helpingthe smokers to reduce smoke or stop smoking, providing various kinds of smokeabatement methods and knowledge and channel of smoke abatement drugs(smoke abatement product or professional smoke abatement institution).Evaluation was performed six month later.Results1. General investigation: (1) 67.7％of 622 investigated families coming from cityand 32.3％from rural communities. Attitude and knowledge score about childrenpassive smoking of parent from city were higher than that from ruralcommunities, displaying that educating level, occupation, income, parentssmoking, smoking age, whether attempt to stop smoking were related to attitudeand knowledge score about passive smoking. After these variances were put intoLogistic regression model, except occupation and educating level, the othervariances still had statistical association with attitude and knowledge score about passive smoking. (2) The attitude about passive smoking of parents were relatedto their knowledge score, OR=1.48 (1.16, 1.89), P＜0.01. (3) The height normalratio of 360 children of the passive smoking group were 81.9％and the weightnormal ratio were 78.6％; the height normal ratio of 262 children of the no passivesmoking group were 95.4％and the weight normal ratio were 88.2％. x~2 analysisdisplaying that there are statistical significance between the height and weightnormal ratio of the two groups, P＜0.01. We can conclude that the height andweight normal ratio of the passive smoking group are lower than that of nopassive smoking group. (4) The recent half-year health situation of children in thepassive smoking group is lower than that in no passive smoking group. Therecent half-year admission rate, respiratory apparatus infection rate of children inthe passive smoking group are higher than that in no passive smoking group.There's no stastic statistical difference between the recent half-year fervescencerate of the children in passive smoking group and no smoking group.2. Effects of intervention (180 in every group)(1) The smoke abatement rate in intervention group is 40.6％and 20.0％in controlgroup. Compared with control group, the smoke abatement rate in interventiongroup increased significantly (P＜0.01=.(2) Compared with control group, thehealth situation of children in intervention group increased significantly and therecent half-year admission rate and infection rate of respiratory apparatusdecreased obviously. (3) The recent half-year fervescence rate (the groups have1～2 times were combined with the groups have more than 3 times) inintervention group is 46.7％and 50.0％in the control group. x~2 analysis indicatedthat P＞0.05 and there was no statistics differences between the two groups. (4)Compared with the control group, the knowledge score about passive smoking ofchildren of parents in the intervention groups increased significantly. (5)Compared with the control group, the recognition attitude score about passivesmoking of children of parents in the intervention groups increased significantly.3. Investigation of the staff (176)(1) The sex, age, marriage conditions, educational background, professional titleand income level have statistic correlation with their attitude and knowledgescore about passive smoking of children. (2) The attitude score of the staff about passive smoking of children have relationships with their knowledge score.Conclusion: The attitude about passive smoking and knowledge score of thechildren's parents have relationships with their educational background, occupation, income, whether their parents smoke and trying to stop smoking; Parents' attitude score are related to knowledge score; Compared with thechildren in no passive smoking group, the height normal rate, weight normal rate, recent half-year health situation of the children in passive smoking groupdecreased, while their recent half-year admission rate, respiratory apparatusinfection rate increased; Educational intervention have effects on the smokeabatement rate, knowledge and attitude score, healthy rate of children, admissionrate and respiratory apparatus infection rate. But there are no effects on reducingthe children's fervescence rate, which need more investigation. The executingrate of clinical instruction about the danger of children passive smoking by thechildren health care related staff is low.
