Analysis of HIV-infection incidence in women in the Tatarstan Republic
<i>AIM.</i> To analyze the long-term dynamics and assess incidence territorial and age structure of infection caused by the human immunodeficiency virus (HIV-infection) in women in the Tatarstan Republic for the period from 1987 to 2015.<i>METHODS.</i> Statistical and graphic-analytical methods were used. Intensive rates of HIV-infection incidence in women (aged 18 years and older), including certain age groups, were calculated and incidence territorial and age structure was analyzed. The incidence average prognostic index in 2016 and its possible maximum and minimum values were determined.<i>RESULTS.</i> From 1996 to 2015 the incidence increased from 0.1 to 31.2 cases per 100 thousand female population. The incidence average prognostic index in 2016 was 37.2 per 100 thousand female population. In adult population (over 18 years) incidence structure the proportion of HIV-infected women in 2001 increased by 2.5 times: from 14.8±0.7% in 2001 to 36.3±1.3% in 2015 (p <0.001). The highest incidence in women was registered in Leninogorsk (76.3 per 100 thousand female population), Bugulma (70.9 per 100 thousand), Yutazinsky (54.8 per 100 thousand female population) districts. There was a statistically significant incidence reduction in the 18-19 years (by 5.7 times), 20-29 years (by 2 times) age groups and increased incidence in women of older age groups.<i>CONCLUSION.</i> Long-term dynamics of HIV-infection incidence in women in the Tatarstan Republic has a significant upward tendency; the shift to older age groups and significant rates variability by Republic districts in the incidence structure in women were revealed.
