- BACKGROUND: Chronic bronchitis is associated with substantial morbidity among elderly adults, but little is known about its prevalence and risk factors in young adults. Our aim was to assess the prevalence and early life risk factors for chronic bronchitis in young adults. METHODS: Questionnaire data and clinical measures from the 24-year follow-up of the Swedish BAMSE cohort were used. We assessed chronic bronchitis (CB) as the combination of cough and mucus production in the morning during winter. Environmental and clinical data from birth and onwards were used for analyses of risk factors. RESULTS: At the 24-year follow-up, 75% (n=3064) participants completed the questionnaire and 2030 performed spirometry. The overall prevalence of CB was 5.5% (n=158) with similar estimates in males and females. Forty-nine percent of CB cases experienced more than 3 self-reported respiratory infections in the last year compared to 18% in non-CB subjects (p<0.001), and 37% of cases were current smokers (versus 19%). Statistically significant lower post-FEV(1)/FVC were observed in CB compared to non-CB subjects (mean z-score -0.06 versus 0.13, p=0.027). Daily smoking (adjusted Odds Ratio, aOR=3.85, p<0.001), air pollution exposure (black carbon during ages 1-4 years old, aOR=1.71 per 1 μg·m(3) increase, p=0.009) and exclusive breast-feeding during four months or more (aOR=0.66, p=0.044) were associated with CB. CONCLUSION: Chronic bronchitis in young adults is associated with recurrent respiratory infections. Besides smoking, our results support role of early life exposures, such as air pollution and exclusive breast-feeding, for respiratory health later in life.
