Comparison of respiratory muscle strength between cigarettes smokers, second-hand smokers and non-cigarettes smokers
Abstract
Background: Smoking is a crucial problem for public health affecting smokers and also, their second-hand smokers. Objectives: To compare the respiratory muscle strength among smoker group, second-hand smoker group, and non-smoker group. Materials and methods: One hundred and twenty males and females, aged between 20-40 years old, were recruited and divided into three groups. Vital signs and respiratory muscle strength were measured in all subjects. Respiratory muscle strength was measured by respiratory pressure meter for three times with one minute resting period. The highest value was selected for data analysis. Results: Result of the study demonstrated that maximal inspiratory and expiratory pressure were not significantly different among three groups (p<0.05). However, there was trend that mean values of the maximal inspiratory and expiratory pressure in non-smoker group was higher than those of other two groups. Conclusion: Smoking might cause a decrease in mean value of the maximal inspiratory and expiratory pressure. Therefore, further study should focus in wider scope of other factors including sample size, age, sex, etc. Journal of Associated Medical Sciences 2017; 50(1): 132-137. Doi: 10.14456/jams.2017.12
