Introduction: Atrial fibrillation (AF) is common with advanced aging and is often asymptomatic and undiagnosed.

Aim: A blood pressure (BP) monitor with embedded algorithm for detecting AF with high diagnostic accuracy during routine automated BP measurement was used to screen individuals aged ≥ 65 years.

Methods: The EMENO health survey (2013-2016) applied a multi-stage stratified random sampling method to select a random general adult population sample in Greece.

Aim: Vaccinations have reduced illnesses and mortality rates globally, yet negative attitudes and uncertainty about them hinder their acceptability and efficacy. The study aims to document Greek parents' immunization perceptions and risk factors.

Methods: Spanning 2014-2017, 447 parents (68% mothers) who participated in the Greek Health Examination Survey EMENO (National Survey of Morbidity and Risk Factors) completed an interview-delivered questionnaire.

Rheumatoid arthritis (RA) is considered the most common form of autoimmune arthritis. The disease's prevalence is around 0.5-1% worldwide, but it seems to vary among different populations.

Background: Although several studies on hepatitis B (HBV), C (HCV) and human immunodeficiency virus (HIV) infection have been conducted in Greece, little is known on the knowledge level of the Greek population towards these three infections. Our aim was to assess the knowledge level of the adult Greek general population about the HBV, HCV and HIV.

Methods: Data were derived from the first general population health survey, Hprolipsis.

Background: Greece was recently reclassified from low- to medium-risk country in terms of cardiovascular disease, with 27% of cardiovascular deaths attributed to hypercholesterolemia. EMENO nationwide survey (2013-2016) assessed the epidemiology of dyslipidemia in the general population in Greece.

Methods: A random sample of adults was drawn by multistage stratified random sampling based on 2011 census.

With big data becoming widely available in healthcare, machine learning algorithms such as random forest (RF) that ignores time-to-event information and random survival forest (RSF) that handles right-censored data are used for individual risk prediction alternatively to the Cox proportional hazards (Cox-PH) model. We aimed to systematically compare RF and RSF with Cox-PH. RSF with three split criteria [log-rank (RSF-LR), log-rank score (RSF-LRS), maximally selected rank statistics (RSF-MSR)]; RF, Cox-PH, and Cox-PH with splines (Cox-S) were evaluated through a simulation study based on real data.

Background: Nationwide data on thyroid disease prevalence in Greece is lacking. Using the national health examination survey EMENO data resources, we aimed to estimate the prevalence of hypothyroidism and hyperthyroidism and associated risk factors in adults living in Greece.

Methods: A random sample of the adults (≥18 years) living in Greece was drawn by multi-stage stratified random sampling based on the 2011 census.

Introduction: The EMENO (National Morbidity and Risk Factors) survey is one of the first and most representative population-based surveys in Greece due to its study design and sampling procedure. We aimed to estimate the prevalence of smoking, secondhand smoking (SHS) and their potential associations with other socioeconomic and unhealthy lifestyle risk factors.

Methods: EMENO is a cross-sectional health status survey conducted in Greece from May 2013 to June 2016.

We aimed to assess the self-perceived health status and the presence of chronic diseases of adult Roma living in settlements in Greece, and to explore associated social determinants of health. Data were derived from the Hprolipsis Health Survey. Multivariable regression models were applied.

Article Synopsis
  • This study evaluated how reliable opportunistic screening programs are in gauging hypertension rates and control in Greece's adult population.
  • Data were analyzed from two surveys: EMENO (2013-2016) used random sampling, while MMM (2019) relied on voluntary screening in urban areas.
  • Findings showed similar hypertension prevalence rates between the two methods, but opportunistic screening underestimated undiagnosed cases and overestimated treatment success, highlighting the need for more comprehensive national studies.

Aims: To report the results of the first national Health Examination Survey (HES) on the prevalence of diabetes, its pharmacologic treatment and level of control, as well as pre-diabetes in Greece.

Methods: Data were derived from the National Survey of Morbidity and Risk Factors (EMENO), in a randomly selected, representative sample of the adult Greek population. Sampling weights were applied to adjust for study design and post-stratification weights to match sample age/sex distribution to the population.

Objective: The evidence on the epidemiology of hypertension in Greece is limited. The prevalence and control of hypertension was assessed in randomly selected adults of the general population in Greece within the nationwide epidemiological study EMENO.

Method: On the basis of 2011 census, EMENO applied a multistage stratified random sampling method involving 577 areas throughout Greece (2013-2016).

Background: Nationwide data on cardiovascular risk factors prevalence is lacking in Greece. This work presents the findings of the national health examination survey EMENO (2013-2016) regarding the prevalence of hypertension, hypercholesterolemia, diabetes, obesity and smoking.

Methods: A random sample of adults (≥18 years) was drawn by multistage stratified random sampling based on 2011 Census.

Background: Although combined antiretroviral therapy has substantially improved the prognosis of people living with HIV (PLHIV), mortality remains higher compared to the general population, mainly due to higher prevalence of non-HIV-related comorbidities, including cardiovascular diseases (CVD). We assessed the prevalence of CVD risk and its contributing factors in adult PLHIV versus general population controls in Greece.

Settings: Cross-sectional comparison of PLHIV (Athens-Multicenter-AIDS-Cohort-Study; AMACS) versus general population controls (National health examination survey; EMENO).
