This study was conducted to estimate the prevalence of smoking among pregnant women living in Japan and to analyze the factors associated with their smoking behavior.
Five hundred institutions with maternity services were randomly sampled from a list of the Japan Association of Obstetricians and Gynecologists. Of these institutions, 260 participated in the survey which was conducted in February 2002. Using a self-reported anonymous questionnaire, a survey on smoking behavior, drinking behavior and sleep status was conducted on pregnant women. Chi-square tests and logistic regression analyses were used to examine the factors associated with their smoking behavior.
Data were obtained from a total of 16,414 pregnant women. The prevalence of smoking during pregnancy was 9.9% [95% confidence interval (CI) 9.4%, 10.4%]. The quit rate of smoking among pregnant woman was 61.9% [95% CI 60.4%, 63.4%]. The odds ratios for smoking during pregnancy were significantly higher in women with relatively young age, less schooling, multiparous, exposure to passive smoking, short sleep duration and in women who drank.
Smoking among pregnant women remains an important public health problem in Japan. It is necessary to promote antismoking measures based on the results of this study.
本研究旨在估算居住在日本的孕妇吸烟率，并分析与她们吸烟行为相关的因素。
从日本妇产科医师协会的名单中随机抽取500家提供产科服务的机构。其中，260家机构参与了2002年2月进行的调查。通过一份自我报告的匿名问卷，对孕妇的吸烟行为、饮酒行为和睡眠状况进行了调查。采用卡方检验和逻辑回归分析来研究与她们吸烟行为相关的因素。
共获得了16414名孕妇的数据。孕期吸烟率为9.9%[95%置信区间（CI）9.4%，10.4%]。孕妇戒烟率为61.9%[95%CI 60.4%，63.4%]。年龄相对较小、受教育程度较低、经产妇、接触过被动吸烟、睡眠时间短以及饮酒的女性孕期吸烟的优势比显著更高。
在日本，孕妇吸烟仍然是一个重要的公共卫生问题。有必要根据本研究结果推广反吸烟措施。
