Background: In the Commonwealth of Independent States (CIS) countries the epidemiology of allergic rhinitis (AR) is poorly characterized. The rationale and design of the CORE (Chronic Obstructive REspiratory diseases) study have been described elsewhere. Methods: A total of 2,842 adults (≥18 years) were recruited (964 in Kiev, Ukraine, 945 in Almaty, Kazakhstan, and 933 in Baku, Azerbaijan) between 2013 and 2015 and interviewed during household visits. Two-step cluster randomization was used for the sampling strategy. Doctor-diagnosed ARwas considered when the respondent had previously been diagnosed with AR by a doctor, self-reported AR symptoms(was defined as watery runny nose during the last 12 months alone or in combination with any of the following: sneezing, nasal obstruction, nasal itching, or conjunctivitis). Results: The prevalence of doctor-diagnosed AR was 33.4, 92.1, and 82.7 per 1,000 persons, and the prevalence of self-reported AR symptoms was 44.7, 97.4, and 85.7 per 1,000 persons, in Ukraine, Kazakhstan, and Azerbaijan, respectively. In Ukraine, the peak of AR symptoms was in May, in Kazakhstan - in May-September, and in Azerbaijan in March-May. Sneezing and nasal congestion were the most frequent symptoms. Pollen as AR trigger was reported by 71.9% respondents in Ukraine, 70.1% in Kazakhstan, and 68.8% in Azerbaijan. Only 35-56% respondents with doctor diagnosed AR have had specific investigations (skin test, analysis for immunoglobulin etc.). The percent of subjects with chronic (nonrespiratory) health condition was higher in the respondents with self-reported AR symptoms compared to rest of the respondent: 100 versus 42% in Ukraine, 100 versus 21% in Kazakhstan, and 100 versus 50% in Azerbaijan, respectively. Conclusion: In CIS countries, the prevalence of self-reported AR symptoms was slightly higher than the prevalence of doctor-diagnosed AR. Compared to countries from other continents, the prevalence of doctor-diagnosed AR was similar; however, the prevalence of AR symptoms seems to be relatively lower.
