[Epidemiologic study of adult bronchial asthma in a Benin hospital environment]

This work is a contribution to the epidemiological study of bronchial asthma in adults in a hospital environment at Cotonou. It is a question of the necessity of admission to hospital of clinical cases. The study has emphasized the following points: Separation according to age has shown that 52% of patients are less than 35 years old, young subjects are in this group. The two sexes are equally involved, with a sex ratio of 1. The different socio-professional groups involved have shown a predominance of those without profession. The main allergic factors identified by questioning are dominated by housedust, which suggests, failing allergological tests, that the role of mites is probably preponderant. There does not seem to be any particular influence of meteorological factors (rain or dryness) on the frequency of crises. Finally, it should be emphasized that technical difficulties make it very difficult to study asthma in Benin.
