This study aims to evaluate the impact of smoking, sex, and body mass index on lung function in university students.
Conducted a cross-sectional study with 630 participants meeting spirometry criteria.
Lung function was assessed using standardized spirometry protocols.
Comparisons were made across smoking status, sex, and BMI categories.
Smokers had a significantly lower FEV1/FVC ratio (0.84) compared to non-smokers (0.86, p < 0.001).
Higher smoking prevalence observed in males (38.6%) than females (14.1%) with OR = 3.86 (p < 0.001).
Increasing BMI correlated with higher lung volumes but lower FEV1/FVC ratios (p < 0.001).
