- Abstract
- Study objectives: The Venn diagram of obstructive lung disease (OLD) has been recently
quantified. We aimed to quantify the proportion of the general population with OLD, and the
intersections of physician-diagnosed asthma, chronic bronchitis (CB), and emphysema in two
Italian general population samples, in relationship to airflow obstruction (AO) determined
through spirometry.
Design and participants: We analyzed data from two prospective studies (4,353 patients) carried
out in the rural area of Po River delta from 1988 to 1991 and in the urban area of Pisa from 1991
to 1993.
Results: Prevalence rates of asthma, CB, and emphysema were 5.3%, 1.5%, and 1.2% in the Po
delta, and 6.5%, 2.5%, and 3.6% in Pisa. A double Venn diagram, which was used to quantify the
distribution of CB, emphysema, and asthma in relation to the presence/absence of AO, identified
15 categories. Isolated AO was the most frequent category (Po delta, 11.0%; Pisa, 6.7%), followed
by asthma only without AO (Po delta, 3.3%; Pisa, 4.3%). The combination of the three OLD
conditions was the only category that always showed higher prevalence rates for those with AO
(Po delta, 0.20%; Pisa, 0.16%) than for those without AO (Po delta, 0.04%; Pisa, 0.05%). Of those
with either OLD or AO, there were 61.4% in Po delta and 38.2% in Pisa with isolated AO, 24.8%
and 41.9%, respectively, with an OLD without AO, and 13.8% and 19.9%, respectively, with
simultaneous OLD and AO. For both genders, the frequency of isolated asthma decreased with
age, while that of isolated AO, CB-emphysema, and the combination of asthma and CBemphysema
increased.
Conclusion: About 18% of the Italian general population samples either reported the presence of
OLD or showed spirometric signs of AO. We confirmed that the Venn diagram of OLD can be
quantified in the general population by extending the mutually exclusive disease categories
(including a concomitant diagnosis of asthma, CB, or emphysema) to 15. (literal)
