目的了解城乡结合部孕妇被动吸烟现状、影响因素及其对不良妊娠结局及新生儿出生体重的影响。方法采用自愿参加的形式,对于2011年1月至2012年11月在我院单胎活产分娩的产妇进行面对面的问卷调查(n=1020)。结果孕妇被动吸烟率84.90%;被动吸烟更多见于20岁以上人群(χ2=64.492,P<0.0001);产次(χ2=55.538,P<0.0001)、文化水平(χ2=80.361,P<0.001)及经济状况(χ2=141.945,P<0.0001)和被动烟草暴露之间存在显著统计学意义;妊娠期高血压(χ2=6.332,P=0.012)、子痫前期(χ2=5.325,P=0.022)更多见于被动吸烟对象;胎儿生长受限更多见于被动吸烟孕妇(χ2=4.126,P=0.042)。结论被动吸烟也能对妊娠结局造成不良影响,与新生儿体重过低有关,不同地区在采取干预措施时更需要加以个体化处理。
Objective To understand the status quo of passive smoking among pregnant women in the urban-rural area, its influencing factors and its effect on adverse pregnancy outcomes and newborn birth weight. Methods The questionnaire was conducted on the basis of voluntary participation in the face-to-face questionnaire (n = 1020) between January 2011 and November 2012 in a pregnant woman with single child birth in our hospital. Results: The passive smoking rate of pregnant women was 84.90%. Passive smoking was more common in people over 20 years of age (χ2 = 64.492, P <0.0001); the level of education (χ2 = 55.538, P <0.0001) (Χ2 = 6.332, P = 0.012), preeclampsia (χ2 = 5.325, P = 0.022), and the economic status (χ2 = 141.945, P <0.0001) and passive tobacco exposure were statistically significant More found in passive smoking; fetal growth restriction found in passive smoking more pregnant women (χ2 = 4.126, P = 0.042). Conclusions Passive smoking can also have an adverse effect on pregnancy outcomes, associated with underweight in newborns, and need to be individualized in different regions when interventions are taken.
