Introduction. In Russia, until now, methodologically correctly organized population studies of LUTS have not been conducted. In this regard, from 2013 to 2016. Research Institute of Urology and Interventional Radiology. N.A Lopatkin conducted a population-based study of the prevalence of LUTS in men in the Bobrovsky district of the Voronezh region, with an assessment of the depenence of symptoms on age and a number of other anthropometric indicators.

Materials and methods. The study population is 40-69 years old men, divided into age groups: 40-49; 50-59; 60-69. Methods of research: questionnaire using the IPSS questionnaire, meas-urement of height (cm), waist circumference (cm), weight (kg), body massindex calculation – BMI(kg/m2). Statistical processing of datawith the definition of the relationship of LUTS with age and anthropometric indicators.

Results. 4876 men were examined, the average age was 54.7 + 0.1. The mean score of IPSS in the general population is 2.8 ± 0.1 points, and in the group with LUTS (IPSS> 1) – 4.7 ± 0.1. Distribution of respondents, depending on the severity of LUTS: IPSS 1-7 (n = 2306) – 47.3%; IPSS 8-19 (n = 496) – 10.2%; IPSS> 19 (n = 39) – 0.8%. The average score of IPSS in the groups was: 2.4 + 0.1; 13.8 + 0.1 and 24.5 + 0.5,respectively.The proportion ofrespondentsin the general populationwith IPSS> 8was 11.0%, 18.8% among all patientswith LUTS. The number of menwith IPSS> 8 points by age groupwas distributed as follows: 40-49 years – 4.9%; 50-59 years – 9.4%; 60-69 years old – 18.8%.The most frequent of all the symptomswas nocturia, itwasrevealed in 52.0% (n = 2535), which accounted for 29.7% of all LUTS. The share of othersymptomswas modest: from 9.2 to 15.0%.Anthropometric indicators: height 174.3 ± 0.1 cm; bodyweight 83.5 ± 0.2 kg; BMI 27.5 ± 0.1;waist cir-cumference 93.2 ± 0.2 cm. Statistical analysis confirmed a directrelationship between the severity of LUTS and age: p 1were older, had significant(p 8 and IPSS> 20 did notreveal significant differences (p> 0.05), except for age indices (p 8.Correlation analysisin the general population did not reveal a relationship between the sum of IPSS respondents' scores and their rostom, body weight, BMI, waist circumference.

Conclusion. The prevalence of LUTS in men 40-69 years in the study region was> 1 – 58.2% for IPSS>, and for IPSS> 8 – 11.0%. The incidence of moderate and severe LUTS (IPSS> 8) progres-sively increased with age: from 15.3 to 26.2%. The relationship between the total sum of IPSS scores and the weight-for-weight indicators of respondentswas not confirmed, norwasthe dependence on them of the symptoms of the phases of accumulation and emptying.
