Little is known about proportions of smokers who maintain smoking after they are aware of a circulatory disorder. The goal was to analyze the extent to which the number of circulatory disorders may be related to being a current smoker.
Cross-sectional survey study with a probability sample of residents in Germany investigated in health examination centers. Questionnaire data of 3,778 ever smoking participants aged 18-79 were used, questions included whether the respondent had ever had hypertension, myocardial infarction, other coronary artery disease, heart failure, stroke, other cerebrovascular disease, peripheral vascular disease, and venous thrombosis. Logistic regression was calculated for circulatory disorders and their number with current smoking as the dependent variable, and odds ratios (OR) are presented adjusted for physician contact, inpatient treatment, smoking cessation counseling, heavy smoking, exercise, overweight and obesity, school education, sex and age.
Among ever smokers who had 1 circulatory disorder, 52.1 % were current smokers and among those who reported that they had 3 or more circulatory disorders 28.0 % were current smokers at the time of the interview. The adjusted odds of being a current smoker were lower for individuals who had ever smoked in life and had 2 or more central circulatory disorders, such as myocardial infarction, heart failure or stroke, than for ever smokers without central circulatory disorder (2 or more disorders: adjusted OR 0.6, 95 % confidence interval, CI, 0.4 to 0.8).
Among those with central circulatory disorders, there is a substantial portion of individuals who smoke despite their disease. The data suggest that only a portion of smokers among the general population seems to be discouraged from smoking by circulatory disorders or its accompanying cognitive or emotional processes.
对于那些知晓患有循环系统疾病后仍继续吸烟的吸烟者比例，人们了解甚少。目的是分析循环系统疾病的数量与当前吸烟状态之间的关联程度。
采用横断面调查研究，对在德国健康检查中心接受调查的居民进行概率抽样。使用了3778名年龄在18 - 79岁之间的曾经吸烟者的问卷数据，问题包括受访者是否曾患有高血压、心肌梗死、其他冠状动脉疾病、心力衰竭、中风、其他脑血管疾病、外周血管疾病和静脉血栓形成。以当前吸烟为因变量，对循环系统疾病及其数量进行逻辑回归分析，并给出经医生接触、住院治疗、戒烟咨询、重度吸烟、运动、超重和肥胖、学校教育、性别和年龄调整后的优势比（OR）。
在曾患1种循环系统疾病的曾经吸烟者中，52.1%为当前吸烟者；而在报告患有3种或更多循环系统疾病的人群中，28.0%在访谈时为当前吸烟者。曾经吸烟且患有2种或更多中枢循环系统疾病（如心肌梗死、心力衰竭或中风）的个体，与没有中枢循环系统疾病的曾经吸烟者相比，当前吸烟的调整后优势较低（2种或更多疾病：调整后OR为0.6，95%置信区间，CI，0.4至0.8）。
在患有中枢循环系统疾病的人群中，有相当一部分人尽管患病仍继续吸烟。数据表明，普通人群中似乎只有一部分吸烟者会因循环系统疾病或其伴随的认知或情感过程而不再吸烟。
