Abstract
Introduction: Tobacco use is one of the most widely spread bad habits. It is one of the leading preventable causes of premature death, disease and disability. The World Health Organization reported that tobacco smoking killed 100 million people worldwide in the 20th century and warned that it could kill one billion people around the world in 21st century. Bangladesh ranked among top tobacco consuming countries where 57,000 people over the age of 30 die each year from tobacco-related illness.
Objective: To assess the effects of tobacco use on parasympathetic nerve function status.
Methods: A total number of 150 male subjects were selected, among them 50 were apparently healthy non-tobacco chewer non-smoker subjects (group A) – control, 50 were apparently healthy tobacco smoker non-chewer (group B) – experimental, 50 were apparently healthy tobacco chewer non-smoker (group C)- experimental. For statistical analysis one way ANOVA (post-hoc) test were performed by computer based software SPSS- 23.0 version for windows. Significance for the statistical test would be predetermined at a probability value of less than 0.05 (p<0.05). Ethical consideration was achieving an informed consent after briefing objectives. Quality was assured through avoidance of missed data, filling of code, regular entry of data and careful data analysis.
Result: In this study smokers revealed significant decreased level of parasympathetic function status in tobacco smokers as compared to tobacco nonsmokers.
Conclusion: Decrease in heart rate occur in tobacco smokers than tobacco nonsmokers.
