| Summary: | 碩士 === 臺北醫學大學 === 公共衛生學系 === 93 === It is well known that smoking harms nearly every organ of the body, causing many diseases and reducing quality of life and life expectancy. Recent years, low-yield nicotine cigarettes become more popular than regular cigarettes because of the market promotion by tobacco industries. And moreover, many people believe that low-yield nicotine cigarettes are less hazardous than regular cigarettes. Is it really true that low-yield nicotine cigarettes are less hazardous?
The aim of this study is to identify the difference of urinary cotinine levels and prevalence of respiratory symptoms between low and high-yield nicotine cigarettes smokers.We collect 133 Taiwanese male adult subjects and divide to 4 groups according to their brand nicotine yield. Each subject filled out a self-administered questionnaire. Urinary cotinine concentrations, pulmonary function test and expired CO concentrations were also measured for every participant.
The result shows that nicotine dependence significantly increased urinary cotinine concentration regardless of the nicotine yield of brands. Significant differences in prevalence of respiratory symptoms were observed among smokers vs nonsmokers, but it can not find between low-yield nicotine smokers and regular cigarettes smokers. The Fagerström Test for Nicotine Dependence were highly correlated with urinary cotinine concentrations. It would be a good indicator of smoking hazardous exposure.
There are no significant differences of cotinine levels and respiratory symptoms were found between low-yield nicotine smokers and regular cigarettes smokers. We suggest the authorities of smoking control should strengthen the education for low-yield nicotine smokers.
