INTRODUCTION
Smoking has been implicated as an etiological factor in airway diseases such as nasopharyngeal and lung cancers, chronic obstructive lung disease (COPD), and asthma.1, 2 One effect of smoking is alteration of the inflammatory response through the immunologic impact in the airways. The response in smokers is different from that in nonsmokers, which is that eosinophil numbers are reduced, whereas neutrophil numbers are raised in sputum from smokers. Furthermore, smoking is known to cause acute
Study Design and Population
Participants were from the Takayama Study, which is a population-based cohort study of men and women 35 years and older who resided in Takayama, Gifu. At baseline (1992), a self-administered questionnaire was given to 36,990 men and women. Participants were asked about their diet, sociodemographic status, anthropometric characteristics, past and current smoking status, quantity of regular physical activity, and medical history. The amount of regular physical activity was evaluated weekly
RESULTS
The characteristics of the population at the beginning of the study are given in Table 1. Participants with either current or former smoking experience at baseline tended to have a lower BMI and to consume more alcohol than never smokers. In women, participants with smoking experience tended to be younger and were less likely to be married than never smokers. Education of 15 years or more was nonsignificantly associated with smoking in men and women. In men, the metabolic equivalent score,
DISCUSSION
In this prospective, community-based study, we found that current smoking was significantly associated with an increased risk of asthma onset in men. Male former smokers had an increased risk of asthma, although this association was not statistically significant. An approximately 3- to 5-fold increased risk was observed in men who had smoked for more than 30 years or more than 20 cigarettes daily. These results indicate that active smoking increases the risk of asthma in men.

Prevalence and risk factors of asthma in mainland China: The CARE study
2018, Respiratory MedicineCitation Excerpt :A 10-year follow-up study showed that smoking was significantly correlated with the risk of asthma and the risk of asthma was three folds higher in smokers than that in non-smokers [23]. Compared with never smokers, current smokers had a significantly increased risk of asthma (hazard ratio, 2.79; 95%CI, 1.18–6.55) [24]. Our study also demonstrated that the prevalence of asthma was higher in smokers than that in non-smokers.

2013, Pharmacological ResearchCitation Excerpt :These risk factors can lead to acute and chronic airway inflammation. Both active and passive smoke exposures increase the risk of asthma onset and chronic airway diseases in adult subjects [55] as well as the development of asthma in children and adolescents [56]. In guinea pigs, chronic exposure to tobacco smoke results in selective AHR to bradykinin and capsaicin, without altering responses to methacholine or histamine [57], suggesting that bradykinin-related peptides play an important role in tobacco smoke-induced AHR.
