Abstract
Background
Nicotine is a highly addictive substance present in tobacco. This study was conducted to assess the prevalence of tobacco use and compare the nicotine dependence among smokers and smokeless tobacco users visiting dental outreach programs of B.P. Koirala Institute of Health Sciences -Dharan, Nepal.
Methods
A cross sectional study was conducted from June 2018 to April 2019. A total of 726 people were selected from participants of dental outreach programs of 6 districts using convenience sampling technique. The data collection was done using semi-structured questionnaire through face to face interview by a single researcher. History of tobacco use and level of nicotine dependency was measured using Nepali translated and validated form of Fagerström Test for Nicotine Dependence for smoking and smokeless. The mean age of the tobacco users was 39.55 ± 15.57 (Range = 19–82 years). Descriptive statistics including the mean, median, percentage, standard deviations and interquartile range were computed. Chi-square test, Fisher’s exact test and odds ratio were calculated where needed.
Results
The overall prevalence of any tobacco use, smoking form, smokeless and both form was found to be 32.8%, 14.9%, 14.3% and 3.6% respectively. Nicotine dependence (moderate and severe) was found in 80% of smokeless tobacco users and 48% of smokers. Among the smokeless tobacco users nicotine dependency was found to be more with female gender (Odds ratio = 4.98, 95%CI = 1.41–17.69, p = 0.01), increase in duration of tobacco use with every 10 years, low socioeconomic status (Odds ratio = 2.75, 95%CI = 1.02–7.40, p = 0.04), married, not using alcohol. Among smokers nicotine dependency was found to be significantly higher with more than 30 years of duration (Odds ratio = 3.35, 95% CI = 1.42–7.92, p = 0.005).
Conclusions
The study concluded that prevalence of tobacco consumption and nicotine dependence was high among the people visiting dental outreach programs. This study incorporated both smoking and smokeless tobacco users. It is high time to develop a policy to control tobacco use along with creating tobacco cessation centers. Tobacco control program are basically focusing on smoking. However, it is very necessary to incorporate in policy level to control smokeless tobacco along with smoking. Tobacco cessation centers will obviously help to quit tobacco among the tobacco users.
