Epidemiological studies show different levels of psoriasis prevalence worldwide.

OBJECTIVE

To study the gender and age characteristics of psoriasis prevalence among the population of the Tambov region in 2015-2019 based on the data analysis from electronic medical records (EMR).

MATERIAL AND METHODS

The study is based on data obtained from the EMC of the population of the Tambov region. Retrieved demographic data and information on the dates of medical care visits to medical organizations in the region; for 2015—2019 identified 8267 patients and 30 293 visits with one of the diagnoses L40.0—L40.9 (psoriasis).

RESULTS

For 2015—2019 the prevalence of psoriasis among the general population increased from 21.8±0.5 (95% CI 20.9–22.7) cases per 10 000 population of the region to 25.4±0.5 (95% CI 24.4–26, 4) cases per 10 000 population of the region; the increase occurred due to three age groups: the largest in the population aged 40–49 years (by 43.9% due to the male population), then group aged 30–39 years (by 35.7% due to female population) and the smallest group aged 50–59 years (by 20.1% due to both genders). The highest prevalence of psoriasis in 2015 was observed in people aged 60–69 years (30.1 cases per 10 000 population of the region), in 2016–2018 — at 50–59 years (29.3; 32.5 and 32.5 cases per 10 000 population of the region, respectively), in 2019 — at 40–49 years, accounting for 34.6 cases per 10 000 population of the region. There was a sharp increase in the prevalence of psoriasis in the age periods from 0–9 years (4.3–6.3 cases per 10 000 population of the region) to 10–19 years (20.0–24.4 cases per 10 000 population of the region), after 70 years the indicator has dropped significantly. The prevalence of psoriasis in the Tambov region is lower in comparison with global indicators. At the same time, most of the data presented on the gender-age characteristics of the psoriasis prevalence and their trends are consistent with foreign researchers’ data.

CONCLUSION

Due to the high incidence, the steady increase in prevalence especially among the most active working-age population, and the trend towards rejuvenation of disease the psoriasis is an important socio-medical problem.
