The Prevalence of Allergic Rhinitis, its Triggers, and Associated Factors in Commonwealth of Independent States Countries (Ukraine, Kazakhstan, and Azerbaijan): Results of the CORE Study

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