ABSTRACT
Background: Cigarette smoking is the leading cause of preventable death in the world. It has deleterious effects on various body systems, especially respiratory system, that leads to reduction in respiratory muscle strength and functional capacity. Due to lack of evidence of the effects of nicotine dependence on these two aspects, there was a need felt to conduct a study to find the association of nicotine dependence on respiratory muscle strength and 6 minute walk distance in adult smokers.
Design: It was a cross-sectional observational study.
Participants: 108 healthy adult smokers participated in the study with the age between 20-40 years, who smoked for more than 1 year, with minimum consumption of 1 cigarette per day. Subjects with BMI of more than 30kg/m2, who had undergone recent surgeries, who suffered from other respiratory conditions and who were engaged in other strength and endurance workout were excluded from the study.
Methodology: Nicotine dependence was determined by Fagerstrom test of Nicotine dependence, Respiratory muscle strength was measured by MicroRPM and Functional capacity was determined by 6 minute walk distance.
Results: The association of Nicotine dependence with respiratory muscle strength and 6 minute walk distance was determined by Spearman correlation coefficient. There was weak positive correlation between nicotine dependence and maximal inspiratory pressure which was statistically significant. There was weak negative correlation between nicotine dependence and 6 minute walk distance which was statistically significant.
Conclusion: This study showed that there was weak positive correlation between nicotine dependence and Maximal inspiratory pressure and weak negative correlation between nicotine dependence and 6 minute walk distance in adult smokers.
Key words: Cigarette smoking, maximal inspiratory pressure, maximal expiratory pressure, Fagerstrom test for nicotine dependence, six minute walk distance.
