Overview
Bronchiectasis affects extremes of age in certain indigenous population. It is difficult to estimate the prevalence because it is often misdiagnosed.
Bronchiectasis Epidemiology and Demographics
- Bronchiectasis predominantly affect extremes of age with a slight female preponderance.[1]
- Very high prevalence has been described in certain indigenous populations such as Alaskan natives with 10-20/1000 children affected.[1]
- A recent US study demonstrated a marked increased prevalence in older populations varying from 4.2/100 000 adults aged 18–34 years to 271.8/100 000 older than 75 years.[1]
- Substantial socioeconomic cost is associated with frequent use of primary and secondary healthcare resources.[1]
- A US epidemiological study of bronchiectasis-associated hospitalizations from 1993 to 2006 demonstrated an average annual hospitalization rate of 16.5/100 000 population with a significant annual increase of 2.4% in men and 3.0% in women.[1]
- Bronchiectasis often goes unrecognized or is misdiagnosed as asthma or chronic obstructive pulmonary disease (COPD), leading to an underestimated prevalence.[1]
