The harmful effects of smoking and factors affecting smoking: maximal voluntary breath-holding time and exercise capacity

Aim: The harmful effects of smoking and its impact on respiratory functions and exercise capacity are well-recognized health concerns in the present day, demanding further investigation. This study aims to assess the association between smoking and respiratory functions and exercise capacity while exploring factors contributing to smoking addiction. Methods: A total of 893 volunteers (mean age: 27.24 years, range: 17-67) participated in this study, with 77% having a university education and 58% being female. Participants were categorized into active smokers, passive smokers, and non-smokers. Maximum Voluntary Breath-holding Time , 6-minute walk test distance, and 30-second chair stand test were used to assess respiratory functions and exercise capacity. Participants provided information about their smoking habits, which was analyzed and reported. Results: There were no statistically significant differences in Maximum Voluntary Breath-holding Time, 6-minute walk test distance, and 30-second chair stand test scores between the groups (p>0.05). However, all smokers exhibited psychological dependence on cigarettes, with 88% showing signs of physical dependence. Smoking initiation was significantly influenced by friends (64%). While 61% of active smokers acknowledged potential health issues associated with smoking, only 92% had not sought medical advice to quit smoking. Conclusion: This study did not demonstrate a conclusive effect of cigarette consumption on respiratory functions and exercise capacity. However, it revealed a strong association between smoking habits and social factors such as friendships. Additionally, most smokers exhibited psychological and physical dependence on cigarettes, emphasizing the need for further research and awareness campaigns to highlight the detrimental consequences of smoking.
