Effects of Cigarettes Smoking on Pulmonary Function among University Students

Abstract

Abstract. Pulmonary function testing is a physiological test that measures how an individual inhales or exhales volumes of air as a function of time. Smoking is greatly associated with reduction of pulmonary function. This research is aimed to estimate the values of peak expiratory flow (PEF), forced expiratory volume in first second (FEV1), forced vital capacity (FVC) and ratio between FEV1/FVC among smoking and non-smoking students in Universiti Tun Hussein Onn Malaysia. Smoking is often related to obstructive disorder with low value of FVC, FEV1 and FEV1/FVC. These pulmonary functions were analyzed based on several variables such as; the number of cigarette smoked per day, duration of smoking, age, and body mass index (BMI) values. 70 healthy volunteers consist of smoking and non-smoking students was selected through several sessions. Students were interviewed to answer questionnaire on demographic, lifestyles and their smoking habit. The pulmonary function tests were conducted according to American Thoracic Society (ATS) standards. The results of the pulmonary functions were analyzed by using SPSS software to compare the pulmonary functions between the smoker and the non-smoker students. The results of the studies showed that the number of cigarettes smoked by respondent and the BMI values were the significant predictors of the decrease in FEV1/FVC values among university students

Impact of cigarettes smoking on undergraduates' lung health and functional performance: Observational cross-sectional study

“…The results of the current study regarding the correlation between the smoking duration and the PF came in accordance with the results reported by Hariri and Wan Mansor who found significant correlation between the number of cigarettes and smoking duration with the reduction in the smoker's FVC and FEV1,[ 22 ] this correlation follows a dose-dependent relationship[ 20 ] and the cigarettes smoking dose was the significant predictor of the level of decrease in the FVC and FEV1. [ 22 ] Additionally; previous studies reported reduced FVC, FEV1, FEV1/FVC and Forced Expiratory Flow rate among adult smokers[ 45 46 ] that indicate affection of the small airways and airways obstruction,[ 47 ] with the severity of affection directly depends on the intensity of cigarette smoking. [ 48 ]…”

“…[ 21 ] Although smoking control is a pivot health concern, unfortunately; There is limited understanding of the impact of cigarette smoking on pulmonary health as well as functional performance (FP) among the university students, this is in part due to the limited number of studies conducted to evaluate the PF and FP among smokers youth and university smoker students. [ 22 ]…”

“…There is still a shortage in the health message regarding the smoking hazards on the youth health and physical performance and there is still a shortage in the utilization of the smoking-related health hazards as a motive for smoking cessation. [ 24 ] Accurate data about the cigarette smoking-related health risks and the PF alternations are mandatory[ 22 ] to correct the alteration in risk perception[ 25 ] and motivate younger adult smokers to quit smoking. [ 26 ]…”

Impact of Duration of Smoking on Lung Function Parameters in Young Adult Males

“…The results of the present study are similar to a study done by Azian Hariri et al, on university students in Malaysia, which also showed a decrease in FVC and FEV1 in smokers. 7 A similar study done by Yang SC showed an irreversible decrease in FEV1 and FVC. 8 However a similar study done in Pakistani adults by Shireen Jawed et al, showed decline in FVC, FEV1 and the FEV1/FVC ratio and also a dose response relation between history of smoking and duration of smoking.…”

A structural equation model of health‐related quality of life among Thai men with chronic obstructive pulmonary disease

“…Although the men in our study were relatively young, nearly half were already living with moderately severe COPD. Our age‐related findings may be partly explained by the men's smoking histories (Hariri & Mansor, 2017). Most of the men in this study were former smokers who had consumed a mean of 38.78 ( SD = 23.32) pack year.…”
