目的：(a)评估来自农村和小城市统计区的孕妇自报吸烟状况的准确性，(b)比较在第一次产前检查时自报不吸烟状况的妇女与自报吸烟状况的妇女的特征，(c)确定预测自报吸烟状况和尿可替宁检测阳性/阴性的特征。环境：七个私人产科办公室，服务于纽约州北部的农村和小城市统计区。参与者：一个方便的样本，包括94名孕妇，她们声称自己在怀孕初期是吸烟者。平均年龄23岁，平均受教育程度11.9岁；95%是白人，65%单身，65%有医疗补助。设计：描述性相关设计。在第一次产前检查时，通过比较吸烟状况的自我报告和尿可替宁测定来确定吸烟和不吸烟状况的敏感性和特异性。还分析了人口统计变量之间的关系以及吸烟状况和尿可替宁的预测因素。结果：首次产前检查时自我报告的吸烟状况与尿可替宁检测的不一致率为16.6%，当可替宁浓度为200 ng/ml时显著高于主动吸烟，34.7%否认吸烟的妇女（特异性为65.3%）和10.4%自称吸烟的妇女（敏感性为89.5%）不准确地报告了自己的吸烟状况(显著性为p
Objectives: (a) to assess the accuracy of self-reported smoking status in pregnant women from rural and small metropolitan statistical areas who stated they were smokers at the onset of pregnancy, (b) to compare the characteristics of these women who self-reported a nonsmoker status at the first prenatal visit with those who reported a smoker status, and (c) to determine the characteristics that predict self-reported smoking status and positive/negative urinary cotinine assays.Setting: Seven private obstetric offices serving rural and small metropolitan statistical areas in upstate New York.Participants: A convenience sample of 94 pregnant women who stated they were smokers at the onset of their pregnancies. Their mean age was 23 years and mean level of education was 11.9 years; 95% were White, 65% were single, and 65% were Medicaid-funded.Design: Descriptive correlational design. At the first prenatal visit, the sensitivity and specificity of smoking and nonsmoking status were determined by comparing self-reports of smoking status with urinary cotinine assays. Data were also analyzed for relationships among demographic variables and for predictors of smoking status and urinary cotinine.Results: The discordance rate between self-reports of smoking status and urinary cotinine assays at the first prenatal visit for the total sample was 16.6%, significant at p 200 ng/ml of cotinine indicating active smoking, 34.7% of women who denied smoking (specificity of 65.3%) and 10.4% of women who stated that they smoked (sensitivity of 89.5%) inaccurately reported their status (significant at p
