Abstract
OBJECTIVE The overall objective in the study was to compare self-reported hearing based on a single question ("how good would you currently rate your hearing?") to measure hearing loss determined by audiometry in a cohort of adolescents. Prevalence of audiometrically measured hearing loss and frequencies of self-reported poor hearing as well as factors that have an impact on self-reported hearing were examined. DESIGN Baseline and 5-year follow-up data of the Ohrkan study were used. Participants filled in a questionnaire and underwent audiometric measurements. STUDY SAMPLE Data from 979 adolescents were analysed. Participants were 54.7% female and aged between 13 and 18 years at baseline and 17-21 years at 5-yr follow-up. RESULTS The single question on self-reported hearing ability achieved a sensitivity of 41.9% and a positive predictive value of 7.1% at baseline. For the 5-yr follow-up, sensitivity was 40.0%, positive predictive value was 13.9%. Factors influencing self-reported poor hearing were gender, tinnitus, "muffled" ears after exposure to loud noise (e.g. after a concert) and low-frequency hearing loss. CONCLUSIONS The single question about hearing ability used in the Ohrkan study is not sufficient to replace audiometry to detect hearing loss as defined in the study in adolescents.

Abstract
OBJECTIVE Among a representative sample of adults aged 50 years and older too (i) determine the prevalence of hearing loss, (ii) evaluate probable causes and risk factors of hearing loss, and (iii) assess the association between hearing loss measured by audiometry and self-report. DESIGN A population-based survey of adults aged 50 and older in Santiago, Chile using the Rapid Assessment of Hearing Loss (RAHL) survey. STUDY SAMPLE 538 participants completed a questionnaire, which included questions on socio-demographic and health characteristics and self-reported hearing loss. Hearing and possible cause of hearing loss was assessed using pure tone audiometry (0.5-4.0 kHz), tympanometry, and otoscopy. RESULTS The prevalence of any level of hearing loss in adults aged 50 years and older was 41% (95% CI 33.2, 49.2). In terms of aetiologies, 89.3% of ears with mild or worse hearing loss were classified as sensorineural. Otoscopy was abnormal in 10.7% of subjects with impacted earwax being the most common finding (4.4%) followed by chronic otitis media (3.5%). Hearing aid usage was 16.6%. Older age, lower socioeconomic position, lack of education, and solvent exposure were significantly associated with hearing loss. CONCLUSION Hearing loss among individuals aged over 50 years was common in Santiago, Chile.

Abstract
Background Despite its marked importance in public health, the prevalence of cognitive impairment (CI) and its associated factors have only rarely been examined in old populations in general or in Russia at all. Objective To assess CI prevalence and its determinants in a very elderly population in Russia. Materials and methods The population-based Ural Very Old Study, conducted in rural and urban region in Bashkortostan/Russia, included 1,526 (81.1%) out of 1,882 eligible individuals aged 85+ years. A series of medical examinations including the Mini-Mental State Examination (MMSE) for the assessment of CI was performed. Results Mini-Mental State Examination data were available for 1,442 (94.5%) individuals (mean age: 88.3 ± 2.9 years; range: 85–103 years). The median MMSE score was 24 (interquartile range: 19, 27). Prevalence of any CI (MMSE score < 24 points) was 701/1,442 [48.6%; 95% confidence interval (CI): 46.0, 51.2]. Prevalence of mild, moderate and severe CI (MMSE score 19–23 points, 10–18 points, and ≤9 points, respectively) was 357/1,442 (24.8%; 95% CI: 22.5, 27.0), 246/1,442 (17.1%; 95% CI: 15.1, 19.0), and 98/1,442 (6.8%; 95% CI: 5.5, 8.1), resp. A lower MMSE score correlated (regression coefficient r2: 0.31) with older age (beta: −0.13; P < 0.001), rural region of habitation (beta: 0.15; P < 0.001), lower level of education (beta: 0.19; P < 0.001), higher depression score (beta: −0.33; P < 0.001) (or alternatively, higher prevalence of hearing loss (beta: −0.10; P = 0.001), worse visual acuity (beta: −0.10; P = 0.001), and lower physical activity (beta: 0.06; P = 0.04). Conclusion In this elderly study population from rural and urban Russia, prevalence of any, mild, moderate and severe CI was 48.6, 24.8, 17.1, and 6.8%, resp. Besides medical and lifestyle factors, vision and hearing impairment were major factors associated with CI.

Abstract
OBJECTIVE To assess the prevalence of vision impairment, hearing impairment and dual sensory impairment (DSI) as combination of vision and hearing impairment, in association with cognitive dysfunction in a population aged 85+ years. METHODS The cross-sectional population-based Ural Very Old Study, conducted in rural and urban Bashkortostan, Russia, between 2017 and 2020, included a detailed ocular and systemic examination with assessment of moderate to severe vision impairment (MSVI)/blindness (best-corrected visual acuity <6/18), moderate to severe hearing loss (MSHL) and cognitive function. SETTING A rural and urban area in Bashkortostan, Russia. PARTICIPANTS Out of 1882 eligible individuals aged 85+ years, 1526 (81.1%) individuals participated. PRIMARY AND SECONDARY OUTCOME MEASURES Prevalence of vision, hearing and DSI and cognitive dysfunction. RESULTS The study included 731 (47.9%) individuals (mean age 88.1±2.7 years; median 87 years, range 85-98 years) with measurements of MSVI/blindness, MSHL and cognitive function. The prevalence of MSVI/blindness, MSHL, DSI and dementia were 51.8% (95% CI 48.2% to 55.5%), 33.1% (95% CI 29.7% to 36.5%), 20.5% (95% CI 17.8% to 23.5%) and 48.2% (95% CI 44.5% to 51.8%), respectively. Lower cognitive function score was associated with lower visual acuity (p<0.001) and higher hearing loss score (p=0.03), after adjusting for older age (p=0.001), rural region of habitation (p=0.003), lower educational level (p<0.001) and higher depression score (p<0.001). Higher dementia prevalence was associated with higher MSHL prevalence (OR 2.18 95% CI 1.59 to 2.98; p<0.001), higher MSVI/blindness prevalence (OR 2.09, 95% CI 1.55 to 2.81; p<0.001) and higher DSI prevalence (OR 2.80, 95% CI 1.92 to 4.07; p<0.001). CONCLUSIONS In this very old, multiethnic population from Russia, DSI (prevalence 20.5%), as compared with hearing impairment (OR 2.18) and vision impairment alone (OR 2.09), had a stronger association (OR 2.80) with dementia. The findings show the importance of hearing and vision impairment, in particular their combined occurrence, for dementia prevalence in an old population.

Abstract
BACKGROUND To examine the prevalence of chronic kidney disease (CKD) and its associations in a Russian population. METHODS Out of 7328 eligible individuals, the population-based cross-sectional Ural Eye and Medical Study included 5899 (80.5%) individuals aged 40+ years and undergoing a detailed medical examination. The estimated glomerular filtration rate (eGFR) was calculated using the Chronic-Kidney-Disease-Epidemiology-Collaboration (CKD-EPI) equation. RESULTS The mean eGFR was 72.3 ± 19.1 mL/min/1.73m2 (median:70.3 mL/min/1.73m2). Prevalence of CKD stage 3a (eGFR< 60 mL/min/1.73m2 and > 45 mL/min/1.73m2), CKD stage 3b (eGFR< 45 mL/min/1.73m2 and > 30 mL/min/1.73m2) and CKD stage 4+ (eGFR< 30 mL/min/1.73m2) were 1351/5841 (23.1%;95% confidence interval (CI):22.1,24.2), 294/5841 (5.0%;95%CI:4.5,5.6), and 29/5841 (0.5%;95%CI:0.3,0.7), respectively. The CKD stage 3+ prevalence increased (P < 0.001) from 11.1% (95%CI:8.4,13.9) in 40-44-year-olds to 56.8% (95%CI:52.8,60.8) in 75 + year-olds. In univariate analysis, CKD stage 3a + prevalence increased with higher systolic blood pressure (P < 0.001). In multivariable analysis, higher prevalence of CKD stage 3a + was associated with older age (P < 0.001;odds ratio (OR):1.06;95%CI:1.05,1.07), female sex (P < 0.001;OR:2.29;95%CI:1.94,2.69), rural region of habitation (P = 0.001;OR:1.29;95%CI:1.11,1.50), higher body mass index (P = 0.03;OR:1.02;95%CI:1.002,1.03), lower prevalence of house ownership (P = 0.02;OR:0.57;95%CI:0.35,0.92), higher prevalence of mostly sitting or standing during work (P < 0.001;OR:1.40;95%CI:1.20,1.64), higher serum concentration of triglycerides (P < 0.001;OR:1.23;95%CI:1.12,1.35) and blood urea nitrogen (P < 0.001;OR:1.33;95%CI:1.27,1.40), lower serum concentration of hemoglobin (P = 0.03;OR:0.99;95%CI:0.99,0.999), and lower prevalence of chronic obstructive pulmonary disease (P < 0.001;OR:0.57;95%CI:0.42,0.78). CONCLUSIONS In this population from Russia aged 40+ years, prevalence of CKD stage 3+ (28.7%;95%CI:27.5,29.8) was relatively high as compared to populations from other countries. Associated factors were older age, female sex, rural region, higher body mass index, a sedentary lifestyle, and lower socioeconomic background.

Abstract
Background Back pain and neck pain are leading causes of the burden of disease worldwide, while information about their prevalence in Russia is missing. Methods The population-based Ural Eye and Medical Study was conducted in a rural and urban region in Bashkortostan/Russia. As part of a detailed systematic examination, we assessed the prevalence of low back pain, thoracic spine pain and neck pain in an interview with standardized questions in 5397 study participants (mean age:58.6 ± 10.6 years;range:40–94 years). Results The mean prevalence of low back pain, thoracic spine pain and neck pain was 2912/5397 (54.0%;95% confidence interval (CI):52.6,55.3), 1271/5397 (23.6%;95%CI:22.4,24.7), and 1570/5397 (29.1%;95%CI:27.9,30.3), respectively. A higher prevalence of low back pain was associated with females (P = 0.04;odds ratio (OR):1.14;95%CI:1.004,1.30), younger age (P < 0.001;OR:0.99;95%CI:0.98,0.99), higher body mass index (P = 0.002;OR:1.02;95%CI:1.01,1.03), lower frequency of vigorous activities during leisure time (P = 0.001;OR:0.79;95%CI:0.69,0.90), more time spent sitting and reclining (P = 0.03;OR:1.00;95%CI:1.00,1.00), higher serum concentration of high-density lipoproteins (P = 0.004;OR:1.10;95%CI:1.03,1.18), higher prothrombin index (P = 0.003;OR:1.01;95%CI:1.003,1.01), higher prevalence of a history of cardiovascular disease (P = 0.004;OR:1.23;95%CI:1.07,1.42), falls (P < 0.004;OR:1.71;95%CI:1.45,2.00), bone fractures (P = 0.01;OR:1.18;95% CI:1.03,1.34), unconsciousness (P < 0.001;OR:1.78;95%CI:1.40,2.25), osteoarthritis (P < 0.001;OR:2.76;95%CI:2.34,3.26), iron-deficiency anemia (P < 0.001;OR:1.87;95%CI:1.41,2.50), and thyroid disorder (P = 0.004;OR:1.37;95%CI:1.10,1.70), fewer days of vegetable intake (P < 0.001;OR:0.89;95%CI:0.85,0.93), smaller amounts of salt intake (P = 0.008;OR:0.97;95%CI:0.94,0.99), higher anxiety score (P < 0.001;OR:1.05;95%CI:1.03,1.06), and in women, history of menopause (P = 0.02;OR:1.36;95%CI:1.05,1.75). The prevalence of thoracic spine pain and neck pain showed similar associations. Conclusions In a Russian population, the prevalence of low back pain, thoracic spine pain and neck pain (54.0, 23.6 and 29.1%, respectively) were correlated with parameters such as the female sex, younger age, higher body mass index, higher anxiety score, higher prevalence of a history of cardiovascular disease, lower frequency of vigorous activities and more time spent sitting or reclining. These data may be of interest for assessing the burden of back and neck pain in Russia as part of the global burden of disease.

Abstract
Background: Although chronic obstructive pulmonary disease and asthma belong to the most important causes of disability and death in all world regions, data about the prevalence of airflow obstruction and asthma in Russia and the associated parameters have been scarce so far. We therefore assessed the prevalence of airflow obstruction and asthma in a Russian population. Methods: The population-based Ural Eye and Medical Study, conducted in a rural and urban region of Bashkortostan/Russia, included 5,392 participants (mean age: 58.6 ± 10.6 years; range: 40-94 years) out of 7,328 eligible individuals. Airflow obstruction was defined spirometrically and asthma by self-reported diagnosis. Results: Airflow obstruction was present in 369 individuals (6.8%; 95% confidence interval (CI): 6.2, 7.5) with an awareness rate of 63.4% (95%CI: 58.5, 68.4) and known duration of 19.5 ± 15.8 years (median: 16 years). Prevalence of undiagnosed airflow obstruction was 2.6% (95%CI: 2.2, 3.1). Higher prevalence of airflow obstruction was associated (multivariable analysis) with higher prevalence of current smoking [P < 0.001; odds ratio (OR): 2.91; 95%CI: 1.76, 4.83] and number of cigarette package years (P < 0.001; OR: 1.03; 95%CI: 1.02, 1.08), female gender (P = 0.03; OR: 1.42; 95%CI: 1.04, 1.93), urban region (P = 0.003; OR: 1.43; 95% CI: 1.12, 1.79), higher prevalence of cardiovascular diseases/stroke (P < 0.001; OR: 1.86; 95%CI: 1.45, 2.39), higher depression score (P = 0.002; OR: 1.05; 95%CI: 1.02, 1.08), and lower physical activity (P = 0.01; OR: 0.71; 95%CI: 0.54, 0.93). Asthma prevalence (2.6%; 95%CI: 2.0, 3.1; known duration: 17.2 ± 15.0 years) was associated with less alcohol consumption (OR: 0.53; 95%CI: 0.33, 0.87; P = 0.01), higher depression score (OR: 1.08; 95%CI: 1.03, 1.12; P < 0.001), and urban region (OR: 0.68; 95CI: 0.49, 0.95; P = 0.0.03). Conclusions: In this Russian population aged 40+ years, the prevalence of airflow obstruction was 6.8% with an awareness rate of 63.4% and smoking as main risk factor. Asthma prevalence was 2.6%.

Abstract
Purpose Non-communicable chronic diseases have become the leading causes of mortality and disease burden worldwide. With information about the frequency of diabetes as a major non-communicable chronic disease in Russia being scarce, we assessed the prevalence of diabetes and its associated factors in a rural and urban population in Russia. Methods The Ural Eye and Medical Study is a population-based study in the city of Ufa/Russia and in villages in a distance of 65 km from Ufa. Inclusion criterion was an age of 40+ years. All study participants underwent a standardized interview and a detailed general examination. Diabetes mellitus was defined by a plasma glucose concentration ≥7.0 mmol/L or self-reported history of physician diagnosis of diabetes. Results Out of a population of 7328 eligible individuals, 5899 individuals (2580 (43.7%) men) (participation rate:80.5%) participated (mean age:59.0±10.7 years (range:40–94 years)). Diabetes mellitus was present in 687 individuals (11.7%;95% confidence interval (CI):11.9,12.5). Awareness rate of having diabetes was 500/687 (72.8%;95%CI:69.0,76.0), with mean known duration of diabetes of 10.0±9.4 years. Known type 1 diabetes was present in 44 subjects and known type 2 diabetes in 358 subjects. Prevalence of undiagnosed diabetes was 3.2% (95%CI:2.7,3.6) in the study population. Among patients with diabetes, 59.1% (95%CI:55.4,62.8) received treatment for diabetes, among whom 237 (58.5%;95%CI:53.7,63.3) individuals had adequate glycemic control. In multivariable analysis, higher prevalence of diabetes mellitus was associated with older age (P<0.001; odds ratio (OR):1.03;95%CI:1.01,1.04), higher body mass index (P<0.001;OR:1.07;95%CI:1.04,1.10), lower prevalence of vigorous daily work (P = 0.002;OR0.68;95%CI:0.53,0.87), positive history of arterial hypertension (P = 0.03;OR:1.40;95%CI:1.03,1.89) and cardiovascular diseases (P = 0.001;OR:1.60;95%CI:1.21,2.13) including heart attacks (P = 0.01;OR:1.80;95%CI:1.15,2.81), higher serum concentration of triglycerides (P<0.001;OR:1.51;95%CI:1.30,1.75), higher systolic blood pressure (P = 0.01;OR:1.01;95%CI:1.01,1.02), higher number of meals taken daily (P<0.001;OR:1.46;95%CI:1.25,1.69), and non-Muslim religion (P = 0.02;OR:0.73;95%CI:0.56,0.94). Conclusions In this ethnically mixed, urban and rural Russian population aged 40+ years, the awareness rate of diabetes (72.8%) was relatively high, while the diabetes prevalence (11.7%) was comparable with that of other countries such as China and the USA. Factors associated with higher diabetes prevalence were similar in Russia and these other countries and included older age, higher body mass index and higher serum concentration of triglycerides, lower prevalence of vigorous daily work, arterial hypertension and cardiovascular diseases.
