Impact of Cigarettes Smoking on Undergraduates’ Lung Health and Functional Performance: Observational Cross‑Sectional Study
Abstract
Background: Cigarettes Smoking is a major social and global health problem. Cigarette smoking continues to be a major contributor to deteriorated health status across different age categories. Clarifying the impact of the cigarette smoking on young adults’ lungs health and functional aspects can serve eliminating further deterioration in health status and establishing proper management regimens. This study aimed to investigate the impact of cigarette smoking on lung health (age and functions) and functional performance in the university smoker students. Methods: One hundred and Thirty eligible volunteer, current smoker students participated in this study to objectively evaluate their pulmonary functions (including forced vital capacity “FVC”, forced expiratory volume in one second “FEV1”, FEV1/FVC, peak expiratory flow rate “PEFr”), lung age and functional performance (via the 6‑minutes’ walk test “6MWT”) and compare “the observed” with “the predicted normal” mean values. Data were analyzed via SPSS program using the student t‑test. Results: There were significant differences (P < 0.05) between the “observed” and the “predicted normal” FVC, FEV1 , FEV1/FVC, PEFr, lung age, and the 6MWT mean values. The “observed” and the “predicted normal” FVC, FEV1 , FEV1/FVC, PEFr, lung age and the 6MWT mean values were [(4.47 ± 0.53, 4.77 ± 0.5 liter), (3.95 ± 0.42, 4.08 ± 0.4 liter), (88.74 ± 7.17, 85.59 ± 4.91%), (550.75 ± 114.96, 572.72 ± 53.02 liter/minute), (32.77 ± 9.44, 21.55 ± 1.37 year), (387.06 ± 56.47, 466.82 ± 18.45 meter)], respectively. Conclusions: Cigarette smoking negatively impacts the lung age, functions, and functional performance of the university smoker students; the concept that can be used to encourage prevention and early smoking cessation.
