Analysis of HIV incidence and its clinical indicators in the Russian Arctic regions

The aim of population based analytical study is comparative analysis of HIV incidence and knowing its social, epidemiological features, also clinical characteristics among registered by AIDS Centers patients in Russian Arctic regions. Materials and methods. Epidemiological study assessed HIV incidence trends, its population testing level and main routs, analyzed age-gender, social, characteristics, evaluated reporting system for new HIV cases, also analyzed clinical indicators among registered patients. Information source were federal statistical observation forms (№ 61 and № 4) for 2007-2021. Results. HIV incidence in 2007-2021 increased in all Arctic regions, especially in Krasnoyarsk Kray (39,3-74,3 per 100 thousand population). HIV testing markedly decreased in Chukotka- by 12,3%, with significant increase in its detectability (HR1,48; 95,0% CI46,72-0,05). Arctic residents are predominantly infected with HIV heterosexually, especially in NaO - 100,0%, Republic of Sakha (Yakutia) - 97.0%, Chukotka and YANAO - 88,0% and 84,5% in 2021 respectively. HIV mainly affects the employable population, aged 25-49 y.o, with predominance of male. In some regions (NAO, Republics Komi, Sakha (Yakutia) in fertile groups prevailed women, especially in Chukotka, where rural residents also predominate among those newly infected with HIV (56,0%). ART coverage of registered patients in the Arctic regions was above the target indicator (75,4%), with the exception of Krasnoyarsk Kray (66,2%). The undetectable level of VL among patients on ART in all Arctic regions was above 60,0%, except for Chukotka (42,9%).
