“…CB is also an age-related disease that is common in elderly individuals. Most studies showed that individuals aged over 50 or 65 years had a greater risk of CB 10,11,27,[37][38][39] and our results were consistent with those of previous studies. Lung function gradually declines after 35 years of age, manifested by the progressive loss of alveolar surface area, dilation of air spaces, reduced mucociliary clearance, and changes in elasticity 40 .…”

Family history of respiratory disease (FHRD) is linked to chronic bronchitis (CB).This study aimed to investigate whether FHRD interacted with age and body mass index (BMI) to increase the risk of CB. A cross-sectional analysis was conducted on 22533 participants enrolled from the Beijing Population Health Cohort Study. Age and BMI were transformed into binary variables using cut-off points of 65 years old and 24 kg/m2, correspondingly. Logistic regression was used to examine the independent and interactive effects among FHRD, age and BMI on CB. Additive interactions between FHRD and age or BMI were further estimated using relative excess risk due to interaction (RERI), attribute proportion due to interaction (AP), and synergy index (S). FHRD was positively associated with the risk of CB (OR 2.21, 95% CI 1.92–2.55 ), which was enhanced by age ≥ 65 years old to 3.43 (95% CI 2.53–4.65) and by BMI ≥ 24 kg/ m2 to 2.99 (95% CI 2.40–3.72). There was no significant additive interaction between FHRD and age or BMI on CB. FHRD, older age and higher BMI were independently associated with increased risk of CB. Nevertheless, no interactive effects between FHRD and age or BMI were observed, and further studies were needed.

“…The prevalence of CB symptoms in individuals aged 40 years or older ranges from 3% to 22% [ 6 , 10 , 11 ]; the variability is due in part to the geographical location [ 6 ] or living in rural areas [ 7 ]. The prevalence of CB increases among smokers (38% in our study had CB) and with the presence of COPD (45% of our COPD population had CB, whereas only 27% of the noCOPD had it), in line with previous reports [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ].…”

“…Cigarette smoking is the most important known risk factor for the development of chronic bronchitis, however CB is also common in the general population, with prevalence estimates varying widely from 3 to 22% of non-smoking adults, variability due in part to geographical location [ 6 , 10 , 11 ]. Occupational and biomass exposures, air pollution, long-term exposure to multiple inhaled smokes vapors and particles, asthma, allergies, and bronchiectasis are some of the known factors contributing to the development of chronic bronchitis in the general population [ 12 ].…”

Background. Chronic bronchitis (CB) importantly affects outcomes in smokers with COPD, but the effects on smokers without COPD are less well known and less emphasized. The aim of our study was to investigate the possible effects of CB on clinical outcomes in smokers without COPD (noCOPD) and compare them with the effects in smokers with COPD (COPD). Methods. For that purpose, we studied 511 smokers, 302 with and 209 without COPD, followed for 10 years in an academic COPD ambulatory setting. Chronic bronchitis was defined as the presence of cough and sputum production for at least 3 months in each of two consecutive years. All subjects underwent clinical and functional examination with spirometry, diffusion capacity (DLco), 6-min walking test (6MWT), mMRC Dyspnoea Scale, COPD Assessment Test (CAT), and recording of annual frequency of exacerbations. All-cause mortality during follow-up was recorded. Results. 27% of noCOPD and 45% of COPD had CB. noCOPD with CB had lower FEV1 and DLco, worse 6MWT, more dyspnoea, a higher number of exacerbations and lower survival than noCOPD without CB. CB did not affect FEV1 decline in noCOPD but it significantly did in COPD. Conclusions. The presence of chronic bronchitis in smokers without COPD will significantly affect symptoms, quality of life, and survival, underlining the importance of recognizing the condition and managing it accordingly.
