ABSTRACT

Introduction: Carbon monoxide (CO) is one of the most common and widely distributed air pollutants. Aim: To detect recent exposure to exhaled carbon monoxide and nicotine dependence among adults attending dental college in Mathura city. Methods: A cross-sectional study was carried out by using hand held breath analyser to measure end expiratory carbon monoxide concentrations in 600 subjects. Questionnaire data were collected to assess the effect of common sources of carbon monoxide exposure on breath carbon monoxide levels. Smokers were used as a carbon monoxide exposed group for comparison with non smokers. Fagerstrom test for nicotine dependence was used to assess the levels of nicotine dependence in smokers Results: The exhaled carbon monoxide level was normal in 227 non smokers and 50 smokers out of 371 non smokers and 229 smokers. The mean carbon monoxide concentration in smokers and non smokers was 2.26±0.805 and 1.39±0.494 (p= 0.000) respectively. Passive smokers and frequent use of motor vehicle were associated with slightly higher carbon monoxide concentration (p= 0.000) in the non smoking group. The frequency and years of smoking was found as a significant risk indicator for nicotine dependence. Conclusion: The present study showed that exhaled carbon monoxide concentration was higher in smokers. In non smokers, exhaled carbon monoxide level was higher in those who were passive smokers, using motor vehicle and fossil fuel. The exhaled CO levels, frequency and years of smoking indicated a marker for nicotine dependence in smokers. Keywords: Carbon monoxide, Smokers, Nicotine dependence
