Passive smoking in patients with chronic obstructive pulmonary diseases

Abstract

The aim of the work is to analyze the passive smoking frequency in patients with chronic obstructive pulmonary disease (COPD) and bronchial asthma (BA).

Materials and methods. A study (interview) was conducted in 100 patients with COPD with II-III stages of the disease, belonging to risk group B aged 51 to 75 years and 155 patients with moderate bronchial asthma (BA) with a controlled or partially controlled course of the disease, aged 20 to 69 years old. The control group consisted of 71 smokers, 45 ex-smokers and 81 non-smokers (aged 20 to 68 years).

Results. A study of passive smoking in patients with chronic obstructive pulmonary diseases showed that, in general, in the COPD group, patients inhaled environmental tobacco smoke daily in 50% of cases, patients with BA — in 41.5% of cases (p>0.05). In the control group, the passive smoking frequency was 67% (p<0.001 with groups of patients). Among patients with COPD, men underwent passive TC in 49% of cases, women — in 56%. The combination of active and passive smoking was in 80% of cases in the COPD smoking group, including 83.6% of cases in men and 74% in wom- en. Among patients with BA, men were forced to regularly inhale environmental tobacco smoke in 34.3% of cases (p<0.05 in the group of COPD patients), women in 46.7% of cases (p>0.05 in the group of COPD patients). The combination of active and passive TC in smoking BA patients occurred in 50% of cases, including 35% of cases in men and 53.7% of cases in women (p<0.05 compared with the group of COPD patients).

Conclusion. Conclusions: passive tobacco smoking is common among patients with COPD and asthma, while there were no significant differences between men and women suffering from chronic obstructive pulmonary disease.
