目的 分析孕妇孕期被动吸烟情况及有关被动吸烟知识、态度和行为(KAP)。方法 以湖北省武汉市3所医院住院分娩和产前检查的孕妇为研究对象,采用面对面访谈方式问卷调查孕妇一般特征、被动吸烟状况及有关被动吸烟的KAP信息。结果 共调查孕妇806人,孕期被动吸烟率为34.9%,无烟家庭共计210户(21.2%);被动吸烟的知识平均得分为(8.75±3.46)分,暴露组得分(8.35±3.57)分低于非暴露组(8.96±3.38)分,2组差异有统计学意义(t=2.32,P=0.021);吸烟态度方面,70%的孕妇反对丈夫抽烟,80%认为公共场所应该禁烟;对待丈夫吸烟采取的行为方式均以劝阻为主,对待其他场所其他吸烟者采取的行为以回避为主,主动劝阻较少,不同场所的回避率为42.0%-73.0%。结论 武汉市孕妇被动吸烟率较高,孕妇有关被动吸烟的知识掌握不足,可能使其无法真正采取有效行为避免被动吸烟。
Objective To examine the prevalence of passive smoking during pregnancy and to investigate the situation of knowledge, attitude,practice (KAP) about passive smoking in pregnant women. Methods The respondents were pregnant women who took prenatal examination or gave birth to their children in three hospitals in Wuhan municipality, Hubei province of China. A face-to-face anonymous interview was carried out among the participants with a questionnaire on demographic information, the exposure of passive and family smoking, and KAP about passive smoking. Results Among the 806 participants,the prevalence rate of passive smoking during pregnancy was 34.9% ;the average score for passive smoking-related KAP was 8.75 ± 3.46 ; and a total of 210 families were smoke-free family ( 21.2% ). Compared to the participants without passive smoking exposure, those with passive smoking had a significantly lower average passive smoking-related KAP score(8.35 ±3.57 vs. 8.96 ±3.38 ,t =2. 32;P =0. 021 0). Of the participants,70% were against to their husbands to smoke and 80% agreed to no smoking in public places. The major countermeasure towards passive smoking from their husbands was discussion, while avoidance was a main way to prevent themselves from passive smoking in public places, with the avoidance rates of 42.0% - 73.0% in various places, among the participants. Conclusion The percentage of passive smoking is relatively high but the knowledge about passive smoking is at a low level among the pregnant women in Wuhan municipality,indicating that passive smoking could not be prevented effectively in the population.
