Prevalence of lower urinary tract symptoms in men according to the results of population research

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 mass index calculation - BMI (kg/m2). Statistical processing of data with 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 of respondents in the general population with IPSS> 8 was 11.0%, 18.8% among all patients with lUtS. The number of men with IPSS> 8 points by age group was 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 symptoms was nocturia, it was revealed in 52.0% (n = 2535), which accounted for 29.7% of all LUTS. The share of other symptoms was modest: from 9.2 to 15.0%. Anthropometric indicators: height 174.3 ± 0.1 cm; body weight 83.5 ± 0.2 kg; BMI 27.5 ± 0.1; waist cir-cumference 93.2 ± 0.2 cm. Statistical analysis confirmed a direct relationship between the severity of LUTS and age: p 1 were older, had significant (p 8 and IPSS> 20 did not reveal significant differences (p> 0.05), except for age indices (p 8. Correlation analysis in 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 respondents was not confirmed, nor was the dependence on them of the symptoms of the phases of accumulation and emptying.
