Negative impact of smoking on lung function: comparing FEV1/FVC values in smokers and non-smokers.

BACKGROUND

Cigarette smoking has been reported as the significant adverse effects on lung function, which can be evaluated by measuring forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and the ratio of FEV1 to FVC (FEV1/FVC) values.

OBJECTIVE

This study investigated the prevalence of tobacco use and nicotine dependence among college students and their stress levels to inform targeted interventions for smoking prevention and cessation.

MATERIAL AND

METHODS

A total of 429 participants were interviewed face-to-face, of which 71.6% were female and 28.4% were male. Pulmonary function tests were exclusively administered to the 9.8% of participants who reported using tobacco.

RESULTS

Our findings revealed a low prevalence of nicotine dependence among college students, with only 6.8% exhibiting moderate or high levels of dependence. Students who reported tobacco use were found to have moderate stress levels,suggesting a potential association between smoking and stress. Chi-square tests revealed that gender, school affiliation,and nicotine dependence were significantly associated with smoking behavior. Long-term smoking (>5 years) was found to be associated with negative health outcomes, such as higher BMI, and increased smoking per day. The analysis of lung function parameters showed that smoking frequency and duration were negatively associated with lung function, while nicotine dependence increased with smoking frequency and duration.

CONCLUSION

Our study suggests that targeted prevention and cessation programs should address these factors to reduce smoking rates among college students.
