Smoking is a well known primary risk factor for chronic bronchitis. However, little is known about the relationship between different types of cigarettes smoked and chronic bronchitis.
To determine the association between chronic bronchitis and the type of cigarette smoked.
A cross-sectional prevalence study was conducted in an urban area (Pelotas) of Southern Brazil. A total of 1053 subjects aged > or = 40 years were interviewed about respiratory symptoms and some risk factors for chronic bronchitis.
After adjustment for confounding factors, the number of daily cigarettes smoked was strongly associated with the risk of chronic bronchitis (odds ratio [OR] = 8.10, 95% CI: 4.46-14.71 for smokers of > or = 20 cigarettes per day compared to non-smokers). Among smokers, maize leaf cigarettes showed the highest risk (OR = 5.43 compared to non-smokers, 95% CI: 2.65-11.13) and filter cigarettes the lowest (OR = 2.19, 95% CI: 1.19-4.03).
In addition to the number of cigarettes smoked, the use of maize leaf cigarettes was shown to have an important independent association with chronic bronchitis.
吸烟是慢性支气管炎众所周知的主要危险因素。然而，对于所吸不同类型香烟与慢性支气管炎之间的关系却知之甚少。
确定慢性支气管炎与所吸香烟类型之间的关联。
在巴西南部的一个市区（佩洛塔斯）进行了一项横断面患病率研究。共对1053名年龄≥40岁的受试者就呼吸道症状和慢性支气管炎的一些危险因素进行了访谈。
在对混杂因素进行调整后，每日吸烟支数与慢性支气管炎风险密切相关（与不吸烟者相比，每天吸≥20支烟者的优势比[OR]=8.10，95%可信区间：4.46 - 14.71）。在吸烟者中，玉米叶卷烟显示出最高风险（与不吸烟者相比，OR = 5.43，95%可信区间：2.65 - 11.13），过滤嘴卷烟风险最低（OR = 2.19，95%可信区间：1.19 - 4.03）。
除吸烟支数外，使用玉米叶卷烟被证明与慢性支气管炎存在重要的独立关联。
