Effect of paternal smoking on the pulmonary functions of adolescent males.

ABSTRACT

Objective: The present study was conducted to evaluate the effect of paternal smoking on the respiratory function of adolescents. Study method: The study group comprised thirty healthy males between the ages of 12–18 years whose fathers were smokers (Group 1). They were compared with age and sex matched thirty active smoker males (Group 2). The control group comprised age and sex matched thirty males who were neither active nor passive smokers (Group 3). Pulmonary function was assessed using Sibelmed Datospir120B spirometer in a closed room. Results: FEV1/FVC ratio and FEF25%–75% (forced expiratory flow at 25%–75% of vital capacity) were significantly lower in the subjects exposed to paternal smoking as compared to non-smokers. Vital capacity & expiratory reserve volume were significantly lower in active smokers as compared to non-smokers. Conclusions: Our findings suggest a significant reduction in indices of lung functions of adolescents exposed to paternal smoke.
