Socioeconomic inequalities cause different tobacco consumption patterns. The purpose of this study was to examine the relationship between educational level and smoking behaviour, including type of tobacco consumption, in lung cancer patients. To this end, epidemiological analyses of 801 lung cancer patients recruited for a case-control study in four public hospitals in Asturias, Spain, between October 2000 and April 2006 were carried out. Smoking behaviour and educational level data were obtained through personal interview. Analyses indicated that the probability of heavy smoking among low educational-level patients was approximately twice as high as for high educational-level patients (RRR>31.2 packs/years=2.04; CI 95%=1.15-3.62; RRR>52packs/years=2.14; CI 95%=0.98-4.64). Low-educated patients were more than three times as likely to be long-time smokers (RRR>40 years=3.30; CI 95%=1.43-7.62). The probability of smoking exclusively black tobacco was almost four times greater in low educational-level patients (RRRblack only=3.72; CI 95%=1.23-11.19). The results show that there are broad educational inequalities with regard to the quantity, duration and type of tobacco consumption among lung cancer patients in Northern Spain.
社会经济不平等导致不同的烟草消费模式。本研究旨在探讨教育水平与肺癌患者吸烟行为（包括烟草消费类型）之间的关系。为此，对 2000 年 10 月至 2006 年 4 月在西班牙阿斯图里亚斯的四家公立医院进行的病例对照研究中招募的 801 名肺癌患者进行了流行病学分析。通过个人访谈获得了吸烟行为和教育水平数据。分析表明，低教育水平患者重度吸烟的可能性大约是高教育水平患者的两倍（RRR>31.2 包/年=2.04；95%CI=1.15-3.62；RRR>52 包/年=2.14；95%CI=0.98-4.64）。低教育水平患者成为长期吸烟者的可能性是高教育水平患者的三倍多（RRR>40 年=3.30；95%CI=1.43-7.62）。低教育水平患者只吸黑烟草的可能性几乎是高教育水平患者的四倍（RRR 只吸黑烟草=3.72；95%CI=1.23-11.19）。结果表明，西班牙北部的肺癌患者在烟草消费的数量、持续时间和类型方面存在广泛的教育不平等。
