The prevalence of self-reported asthma was studied in a group of Turki
sh adults using the European Community Respiratory Health Survey (ECRH
S) questionnaire distributed during 1994 local elections in Ankara, Tu
rkey. A total of 2020 questionnaires were issued and 1820(90%) were re
turned. The mean age of the subjects was 34.5 +/- 10.2 years. The prev
alence of wheezing at any time in the past was 39.1% which is much hig
her than has been reported in the literature. However, only 21.7% of t
he study population had wheezing in the year preceding the survey and
2.9% of them had severe asthma attacks. The prevlaences of nocturnal w
heeze, nocturnal cough and morning tightness were higher in females (P
=0.05 for each). The results of this study showed a high rate of repor
ted symptoms but a low rate of diagnosis and treatment of asthma among
the adult population in Ankara.
