Material and methods. In the cross-sectional population-based study of general unorganized population of Tomsk aged 25-64 years ultrasound screening examination of the carotid arteries was done for detection of atherosclerotic plaques (plaque). As potential plaque determinants the following factors were studied: age, gender, smoking, low and high density lipoproteins (LDL-C and HDL-C), triglycerides, arterial hypertension, body mass index (BMI), low educational status (LES), high-sensitive C-reactive protein, glucose, diabetes mellitus, antihypertensive and hypolipidemic therapy. Study of relationships was carried out with logistic regression analysis. The error probability of less than 5% was considered statistically significant.Results. In the crude analysis most of the determinants under study showed statistically significant relationship with plaque presence. After adjustment for age and sex, LDL-C, smoking and LES were associated with CAS prevalence. In multivariable regression analysis 9 risk factors appeared to be independently associated with plaque presence, wherein age, male sex, LDL-C, BMI and HDL-C were the most significant. In the participants of 50 years and older the smoking effect was the next in significance after LDL-C.Conclusion. The results obtained focus attention on the comparative value of the major atherogenic risk factors and suggest that currently effective and timely control of LDL-C is of primary importance for prevention of carotid atherosclerosis in the general working-age population. As well the findings of the study evidence that at the population level smoking is still one of the leading atherogenic risk factors.

Abstract Background Depression is an ever more common chronic non communicable disease and its control constitutes a growing public health concern given its links with a number of co-morbidities, including diabetes mellitus. The study aimed to estimate the prevalence of depression at a population level across groups of different glycaemic status, whilst establishing its socioeconomic phenotypic characteristics.Methods A nationally representative cross-sectional study was conducted in Malta between 2014 and 2016. Participants were categorized into different sub-populations according to their glycaemic status. Depression prevalence rates and socio-economic characteristics for each sub-population were established. Multiple regression analysis was performed to identify links with depression.Results Depression was prevalent in 17.15% (CI 95%: 16.01 – 18.36) with a female predominance. The normoglycaemic sub-population had the highest depression rates. However, persons with known diabetes had a higher probability of having a history of depression (OR:2.36 CI 95%:1.12 – 4.96), as well as with being of the female gender, having lower educational status, having a history of smoking tobacco and having established cardiovascular disease.Conclusions Depression was highly prevalent among the normoglycaemic population especially as age progress. Physicians in primary care should implement a depression screening tool as part of their routine health check-ups, with special attention to those with cardiovascular co-morbidities and any signs of psycho-socio-economic burden.

Objective: Carotid atherosclerosis is a known marker of increased cardiovascular risk. We aimed to assess the current epidemiology of carotid atherosclerosis, carotid plaque and related risk factors in rural northeast China.Methods: The population-based, cross-sectional study was conducted in 5,838 adults aged ≥40 years residing in rural northeast China in 2017–2018. A multi-stage cluster sampling method was used to select the representative sample. Carotid atherosclerosis was defined as carotid intima-media thickness (CIMT) ≥1.0 mm or presence of plaque.Results: The mean CIMT was 0.72 ± 0.13 mm and increased with age in this population. Among 2,457 individuals with carotid atherosclerosis, 2,333 were diagnosed with carotid plaque, and 210 individuals were moderate or severe carotid stenosis. Crude prevalence of carotid atherosclerosis and plaque were 42.1 and 40.0%, significantly higher in men than in women (p < 0.001). The age-standardized prevalence of carotid atherosclerosis and carotid plaque were 33.1 and 31.5%, respectively. Advancing age, men, hypertension, diabetes, current smoking, ever-smoking and lack of exercise were risk factors for carotid atherosclerosis. Hypertension (69.1%), dyslipidemia (26.0%) and diabetes (16.1%) were highly prevalent in participants with carotid atherosclerosis. However, the control rates of those comorbidities were frustratingly low (4.7, 8.2, and 14.2%, respectively).Conclusions: The high prevalence of carotid atherosclerosis, carotid plaque, carotid stenosis and uncontrolled risk factors indicated the high burden of cardiovascular disease in rural northeast China, particularly in men. Strategies of prevention and management of atherosclerosis and related risk factors were urgently needed in rural northeast China.

Abstract Introduction Depression is a growing public health concern and associated with a number of co-morbidities including diabetes mellitus. The aim was to estimate the prevalence of depression at a population level across different glycaemic statuses while establishing phenotypic characteristics of this sub-population. Methods A national representative cross-sectional study was conducted in Malta (2014-6). Participants were categorized into different sub-populations according to their glycaemic status. Depression prevalence rates and bio-socio-economic characteristics for each sub-population were established. Multiple regression analyses performed to identify links between glycaemic status and depression. Results Depression was prevalent in 17.15% of our study population (CI 95%: 16.01 - 18.36) with a female predominance. The normoglycaemic sub-population had the highest depression rates. Persons with known diabetes had a higher probability of having a history of depression (OR:2.36 CI 95%:1.12 - 4.96), as well as with being of female gender, having lower educational status, smoking tobacco and having established cardiovascular disease. Conclusions Depression was highly prevalent among the normoglycaemic population. Primary care physicians should implement a depression screening tool as part of their routine health check-ups, with special attention to those with cardiovascular co-morbidities and low socioeconomic status. Key messages Depression prevalent mostly in the normoglycemic population. Screening for depression should be part of routine health check-ups.

AbstractBackgroundPopulation-based serological surveys provide a means for assessing the immunologic landscape of a community, without the biases related to health-seeking behaviors and testing practices typically associated with rt-PCR testing. This study assesses SARS-CoV-2 seroprevalence over the first epidemic wave in Canton Geneva, Switzerland, as well as biological and socio-economic risk factors for infection and symptoms associated with IgG seropositivity.Methods and findingsBetween April 6 and June 30, 2020, former participants of a yearly representative cross-sectional survey of the 20-75-year-old population of the canton of Geneva were invited to participate in a seroprevalence study, along with household members five years and older. We collected blood and tested it for anti-SARS-CoV-2 immunoglobulins G (IgG). Questionnaires were self-administered. We estimated seroprevalence with a Bayesian model accounting for test performance and sampling design. We included 8344 participants (53.5% women, mean age 46.9 years). The population-level seroprevalence over the 12-week study period was 7.8 % (95% Credible Interval (CrI) 6.8-8.9), accounting for sex, age and household random effects. Seroprevalence was highest among 18-49 year olds (9.5%, 95%CrI 8.1-10.9), with young children (5-9 years) and those >65 years having significantly lower seroprevalence (4.3% and 4.7-5.4% respectively). Men were more likely to be seropositive than women (relative risk 1.2, 95%CrI 1.1-1.4). Odds of seropositivity were reduced for female retirees (0.46, 95%CI 0.23-0.93) and unemployed men (0.35, 95%CI 0.13-1.0) compared to employed individuals, and for current smokers (0.36, 95%CI 0.23-0.55) compared to never-smokers. We found no significant association between occupation, level of education, neighborhood income and the risk of being seropositive. Symptoms most strongly associated with seropositivity were anosmia/dysgeusia, loss of appetite, fever, fatigue and myalgia and/or arthralgia. Thirteen percent of seropositive participants reported no symptoms.ConclusionsOur results confirm a low population seroprevalence of anti-SARS-CoV-2 antibodies after the first wave in Geneva, a region hard hit by the COVID-19 pandemic. Socioeconomic factors were not associated with seropositivity in this sample. The elderly and young children were less frequently seropositive, though it is not clear how biology and behaviors shape these differences. These specificities should be considered when assessing the need for targeted public health measures.

AbstractThe purpose of the study was to weigh the community burden of chikungunya determinants on Reunion island. Risk factors were investigated within a subset of 2101 adult persons from a population-based cross-sectional serosurvey, using Poisson regression models for dichotomous outcomes. Design-based risk ratios and population attributable fractions (PAF) were generated distinguishing individual and contextual (i.e. that affect individuals collectively) determinants. The disease burden attributable to contextual determinants was twice that of individual determinants (overall PAF value 89.5% vs. 44.1%). In a model regrouping both categories of determinants, the independent risk factors were by decreasing PAF values: an interaction term between the reporting of a chikungunya history in the neighbourhood and individual house (PAF 45.9%), a maximal temperature of the month preceding the infection higher than 28.5 °C (PAF 25.7%), a socio-economically disadvantaged neighbourhood (PAF 19.0%), altitude of dwelling (PAF 13.1%), cumulated rainfalls of the month preceding the infection higher than 65 mm (PAF 12.6%), occupational inactivity (PAF 11.6%), poor knowledge on chikungunya transmission (PAF 7.3%) and obesity/overweight (PAF 5.2%). Taken together, these covariates and their underlying causative factors uncovered 80.8% of chikungunya at population level. Our findings lend support to a major role of contextual risk factors in chikungunya virus outbreaks.

Abstract Background Antimicrobial resistance is a global health emergency. Persons colonized with multidrug-resistant organisms (MDROs) are at risk for developing subsequent multidrug-resistant infections, as colonization represents an important precursor to invasive infection. Despite reports documenting the worldwide dissemination of MDROs, fundamental questions remain regarding the burden of resistance, metrics to measure prevalence, and determinants of spread. We describe a multi-site colonization survey protocol that aims to quantify the population-based prevalence and associated risk factors for colonization with high-threat MDROs among community dwelling participants and patients admitted to hospitals within a defined population-catchment area. Methods Researchers in five countries (Bangladesh, Chile, Guatemala, Kenya, and India) will conduct a cross-sectional, population-based prevalence survey consisting of a risk factor questionnaire and collection of specimens to evaluate colonization with three high-threat MDROs: extended-spectrum cephalosporin-resistant Enterobacteriaceae (ESCrE), carbapenem-resistant Enterobacteriaceae (CRE), and methicillin-resistant Staphylococcus aureus (MRSA). Healthy adults residing in a household within the sampling area will be enrolled in addition to eligible hospitalized adults. Colonizing isolates of these MDROs will be compared by multilocus sequence typing (MLST) to routinely collected invasive clinical isolates, where available, to determine potential pathogenicity. A colonizing MDRO isolate will be categorized as potentially pathogenic if the MLST pattern of the colonizing isolate matches the MLST pattern of an invasive clinical isolate. The outcomes of this study will be estimates of the population-based prevalence of colonization with ESCrE, CRE, and MRSA; determination of the proportion of colonizing ESCrE, CRE, and MRSA with pathogenic characteristics based on MLST; identification of factors independently associated with ESCrE, CRE, and MRSA colonization; and creation an archive of ESCrE, CRE, and MRSA isolates for future study. Discussion This is the first study to use a common protocol to evaluate population-based prevalence and risk factors associated with MDRO colonization among community-dwelling and hospitalized adults in multiple countries with diverse epidemiological conditions, including low- and middle-income settings. The results will be used to better describe the global epidemiology of MDROs and guide the development of mitigation strategies in both community and healthcare settings. These standardized baseline surveys can also inform future studies seeking to further characterize MDRO epidemiology globally.

Abstract The progression and asymmetry of age-related hearing loss has not been well characterized in those 80 years of age and older because public datasets mask upper extremes of age to protect anonymity. We aimed to model the progression and asymmetry of hearing loss in the older old using a representative, national database. This was a cross-sectional, multicentered US epidemiologic analysis using the National Health and Nutrition Examination Study (NHANES) 2005-2006, 2009-2010, and 2011-2012 cycles. Subjects included non-institutionalized, civilian adults 80 years and older (n=621). Federal security clearance was granted to access publicly-restricted age data. Outcome measures included pure-tone average air conduction thresholds and the 4-frequency pure tone average (PTA). 621 subjects were 80 years old or older (mean=84.2 years, range=80-104 years), representing 10,600,197 Americans. Hearing loss exhibited constant acceleration across the adult lifespan at a rate of 0.0052 dB/year2 (95% CI = 0.0049, 0.0055). Compounded over a lifetime, the velocity of hearing loss would increase five-fold, from 0.2 dB loss/year at age 20 to 1 dB loss/year at age 100. This model predicted mean PTA within 2 dB of accuracy for most ages between 20 and 100 years. There was no change in the asymmetry of hearing loss with increasing age over 80 years (linear regression coefficient of asymmetry over age=0.07 (95% CI=-0.01, 0.24). In conclusion, hearing loss steadily and predictably accelerates across the adult lifespan to at least age 100, becoming near-universal. These population-level statistics will guide treatment and policy recommendations for hearing health in the older old.

AbstractThis cross-sectional study investigated the characteristics of cervical HPV infection in Changsha area and explored the influence of Candida vaginitis on this infection. From 11 August 2017 to 11 September 2018, 12,628 outpatient participants ranged from 19 to 84 years old were enrolled and analyzed. HPV DNA was amplified and tested by HPV GenoArray Test Kit. The vaginal ecology was detected by microscopic and biochemistry examinations. The diagnosis of Candida vaginitis was based on microscopic examination (spores, and/or hypha) and biochemical testing (galactosidase) for vaginal discharge by experts. Statistical analyses were performed using SAS 9.4. Continuous and categorical variables were analyzed by t-tests and by Chi-square tests, respectively. HPV infection risk factors were analyzed using multivariate logistic regression. Of the total number of participants, 1753 were infected with HPV (13.88%). Females aged ≥ 40 to < 50 years constituted the largest population of HPV-infected females (31.26%). The top 5 HPV subtypes affecting this population of 1753 infected females were the following: HPV-52 (28.01%), HPV-58 (14.83%), CP8304 (11.47%), HPV-53 (10.84%), and HPV-39 (9.64%). Age (OR 1.01; 95% CI 1–1.01; P < 0.05) and alcohol consumption (OR 1.30; 95% CI 1.09–1.56; P < 0.01) were found to be risk factors for HPV infection. However, the presence of Candida in the vaginal flora was found to be a protective factor against HPV infection (OR 0.62; 95% CI 0.48–0.8; P < 0.001). Comparing with our previous study of 2016, we conclude that the subtype distribution of HPV infection is relatively constant in Changsha. Our data suggest a negative correlation between vaginal Candida and HPV, however, more radical HPV management is required in this area for perimenopausal women and those who regularly consume alcohol.

ObjectivesData on the problem of physical activity-related injury (PARI) in university students and the risk factors for PARI among different genders are rare. We conducted a multicentre population-based study to investigate the occurrence of PARI and to explore the gender-specific risk factors for PARI among Chinese university students.DesignCross-sectional study.ParticipantsA total of 5341 students in grades 1–3 at eight universities in four Chinese cities were selected to complete the online questionnaires during March and April 2017. The questionnaires assessed sociodemographic characteristics, physical activity PA) involvement, sleep duration, sedentary behaviour and PARI experiences in the past 12 months.Main outcome measuresPARI during the past 12 months.ResultsAmong the 5341 participants, 1293 suffered from at least one PARI in the past 12 months, with an overall incidence rate of 24.2% (males: 26.2%, females: 23.2%) and an injury risk of 0.38 injuries/student/year (males: 0.48, females: 0.32). Over half of the injured (57.3%) experienced a withdrawal time of PA and nearly two-fifths (39.6%) required medical attention. Irrespective of gender, Shantou and Xi’an students, sports team members and those who engaged in sports and leisure-time vigorous-intensity PA (VPA) at a higher frequency were more likely to suffer from PARI. Male students who participated in sports and leisure-time VPA for long durations had a greater likelihood of sustaining PARI, while having a chronic condition and being involved in sports and leisure-time moderate-intensity PA at a higher frequency and longer duration were potential contributors to PARI among females.ConclusionsThe occurrence of PARI and its risk factors differed by gender, which provides a direction towards developing targeted and effective gender-specific preventative programmes to protect Chinese university students from PARI.
