The Impact of the COVID-19 Pandemic on Elite Swimmers and Water Polo Players: Lessons for the Future.

BACKGROUND: The COVID-19 pandemic has disrupted global daily life, including the world of elite athletes. This paper examines the multifaceted impact the COVID-19 pandemic had on elite swimmers and water polo athletes, specifically their mental health, their concerns over the virus, their intentions of getting vaccinated, and sleep disturbances that they may have faced. METHODS: We conducted a cross-sectional study on elite swimmers and water polo players, using an anonymous questionnaire. RESULTS: A total of 200 elite athletes participated. The majority of the participants reported a negative impact on their mental health, screened positive for insomnia (n = 107 (53.5%), with females (n = 101; 57.7%), swimmers (n = 100, 66.7%), and university students (n = 71, 71.7%) being more vulnerable (p < 0.001). Concerns about contracting the disease especially during important training or tournament periods and potential career disruption also affected their psychological well-being. While the majority (75%) had the intention of getting vaccinated, an alarming percentage was yet uncertain over its decision. CONCLUSIONS: This study highlights the significant psychological distress faced by elite aquatic athletes during the pandemic. It emphasizes the difficulties faced by elite swimmers and water polo athletes and determines not only the importance of addressing the vaccination intentions of athletes, but also how critical it is to confront the challenges they face both for their personal health and for the restoration of world sports to their pre-pandemic state. More large-scale studies are required to inform policies targeted at minimizing disruption to the athletes' career, provision of information on preventive measures and vaccination, and improvement in psychological well-being in case of similar major public health issues in the future. Additionally, this study calls for further research to explore the unique challenges faced by aquatic athletes, such as those related to their training environments and fear of contagion, to better support them in future public health crises.

Hepatitis B, C and human immunodeficiency virus knowledge among the general greek population: results from the Hprolipsis nationwide survey.

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. The sample was selected by multistage stratified random sampling. A standardized questionnaire was administered by trained interviewers during home visits. A knowledge score was constructed based on responses to 17 per infection selected items and categorized in three levels; high (12-17 correct replies) medium (6-11) and low (0-5). Among 8,341 eligible individuals, 6,006 were recruited (response rate: 72%) and 5,878 adults (≥ 18 years) were included in the analysis. The statistical analysis accounted for the study design. RESULTS: Only 30.4%, 21.6%, and 29.6% of the participants had a high overall knowledge level of HBV, HCV and HIV, respectively. These low percentages were mainly attributed to the high levels of misconception about transmission modes (65.9%, 67.2%, and 67.9%, respectively). Results showed that increasing age and living out of the big metropolitan cities were associated with decreased odds of having higher knowledge. Female gender, higher education level, higher monthly family income, higher medical risk score, history of testing and being born in Greece or Cyprus, were associated with increased odds of having higher knowledge. CONCLUSIONS: There are significant knowledge gaps in the Greek general population regarding modes of transmission, preventive measures and treatment availability for HBV, HCV and HIV. There is an urgent need for large scale but also localized awareness activities targeted to less privileged populations, to fill the gaps in knowledge and increase population engagement in preventive measures.

Prevalence and Predictors of COVID-19 Vaccination Acceptance among Greek Health Care Workers and Administrative Officers of Primary Health Care Centers: A Nationwide Study Indicating Aspects for a Role Model.

Background: Τhe study aims to identify factors associated with COVID-19 vaccine acceptance and to investigate knowledge and perceptions of Primary Health Care Centers (PHCC) personnel, who acted as pioneers in the national COVID-19 vaccination strategy. Methods and Materials: A nationwide cross-sectional survey was conducted by distributing an online anonymous questionnaire comprising 25 questions during the first semester of 2021. Results: Approximately 85.3% of the 1136 respondents (response rate 28.4%) were vaccinated or intended to be. The acceptance of seasonal flu vaccine (aOR: 3.29, 95%CI: 2.08−5.20), correct COVID-19 vaccine knowledge (aOR: 8.37, 95%CI: 4.81−14.59) and lack of concern regarding vaccine novelty (aOR: 6.18, 95%CI: 3.91−9.77) were positively correlated with vaccine acceptance. Vaccinated respondents were more likely to be physicians (aOR: 2.29, 95%CI: 1.03−5.09) or administrative staff (aOR: 2.65, 95%CI: 1.18−5.97) compared to nursing stuff. Reasons for vaccine hesitancy included inadequate information (37.8%) and vaccine safety (31.9%). Vaccine acceptance was strongly correlated (Spearman's correlation coefficient r = 0.991, p < 0.001) between PHCC personnel and the general population of each health district. Conclusions: COVID-19 vaccine acceptance among PHCC personnel in Greece was comparably high, but specific groups (nurses) were hesitant. As the survey's target population could serve as a role model for the community, efforts should be made to improve COVID-19 vaccine acceptance.

Prevalence and correlates of physical inactivity in adults across 28 European countries.

BACKGROUND: Physical activity/inactivity is impacted by a plethora of intertwined factors. There are a limited number of studies on physical activity/inactivity that provide a European cross-country perspective. This study aims to present the prevalence and correlates of physical activity in adults across the 28 European Union (EU) member states. METHODS: This is a secondary dataset analysis of the Special Eurobarometer 472 data on physical activity. The cross-sectional survey was conducted during December 2-11 in 2017 across 28 European countries. The data consisted of ∼1000 respondents aged ≧15 years per country. The current analysis was restricted to adults aged 18-64 years (n = 19 645). RESULTS: More than one in three (36.2%, 95% CI: 35.1-37.3) adults in the EU were physically inactive, with substantial cross-country differences noted. Women were less likely than men to be adequately or highly physically active (aOR: 0.86, 95% CI: 0.78-0.95). Similarly, adults at the age of 40-54 (aOR: 0.65, 95% CI: 0.52-0.81) and 55-64 (aOR: 0.61, 95% CI: 0.49-0.77) were less likely to have moderate or high levels of physical activity in comparison with those 18-24 years of age. Finally, high SES was positively associated with physical activity (aOR: 1.4, 95% CI: 1.16-1.69). CONCLUSIONS: A notable percentage of adults in Europe are physically inactive. Further research is needed to elucidate the factors behind the cross-country differences and identify potential policy actions that may support adopting a physically active lifestyle and decrease the inequalities related to physical activity across Europe.

Acceptability of COVID-19 Vaccination among Greek Health Professionals.

Health Care Workers are at the front line of the fight against Covid-19. The aim of this study was to evaluate the acceptability of vaccination against COVID-19 among health professionals (physicians, dentists, pharmacists) two weeks prior to the start of the Greek vaccination campaign against COVID-19. A cross-sectional online survey was conducted over the period 15-22 December 2020 in 340 health professionals in Central Greece. We found a high level of acceptance for COVID-19 vaccine (78.5%) and a high vaccination coverage for the influenza vaccine (74%). Age > 45 years (OR = 2.01; 95% C.I. = 2.01-4.3), absence of fear over vaccine safety (OR = 4.09; 95% C.I. = 1.36-12.3), and information received from the Greek public health authorities (OR = 11.14; 95% C.I. = 5.48-22.6), were factors independently associated with the likelihood of COVID-19 vaccination acceptance. Our study indicates a high level of the COVID-19 vaccination acceptance among physicians, dentists and pharmacists. Nevertheless, several interventions can be implemented to increase acceptance of vaccine among health-care workers (HCWs) and could be especially directed at younger and vaccine-hesitant health care workers due to fear of vaccine side-effects. Last, our results provide some evidence that receiving vaccine-related information from the Greek Center for Diseases Control (E.O.D.Y.) could reduce the drivers of hesitancy and enhance the acceptability of COVID-19 vaccination.

Employment and suicidal rates during economic recession: A country-targeted integrative review.

BACKGROUND: The economic crisis' effects on suicide rates for countries undergoing or exiting austerity measures have been widely debated. This integrative review aimed to identify, appraise, and synthesize available evidence of employment status effect on suicide mortality rates in Greece during the recent economic recession period. METHODS: A literature review of studies evaluating suicides in the general Greek population, as well as across age and gender groups, in relation to employment during the economic crisis period was performed. PubMed electronic database was searched for relevant articles published in English or Greek language from 2009 up to February 2020. Appraisal was carried out based on the Hierarchy of Evidence Rating System and the GRADE guidelines. RESULTS: A total of 24 articles met all inclusion criteria with 20 of them at level IV, 2 at level VII, and 2 at level VIII. A total of 18 studies reported increase of suicide rates during the economic recession period. About 12 studies examined the co-relation between unemployment and suicide rate, with ten studies showing a positive correlation. Moreover, thirteen studies reported data on the effect of gender and age variables on suicide rates. CONCLUSION: Evidence shows that suicide mortality rates in Greece increased after the eruption of economic recession, particularly after the implementation of radical austerity measures (2011-2014). This increase was positively correlated with unemployment and was more prominent among males of working age. Further in depth epidemiological research of regional variations in terms of profile and contributing or enabling factors of suicidal behavior is needed.

Burnout and associated factors among Greek substance use disorder treatment providers during economic crisis.

Crisis and austerity in Greece could have influenced the risk of burnout among substance use disorder treatment providers. We aimed to investigate the prevalence of burnout and its associated factors among Greek substance use disorder treatment providers during economic crisis. A cross-sectional study was conducted in 2016. In particular, employees at the substance use treatment program of Athens (n = 180), a branch of the Greek Organization against Drugs were invited to participate. Almost all participants reported medical supplies shortages related to the economic crisis. Increasing job demands, staff reduction and limited job autonomy were independent risk factors for burnout. These factors are crisis-related. In conclusion, we found high rates of burnout among substance abuse treatment personnel in Greece. These respondents are a bellwether of the effects of economic crisis. Economic crisis can produce a profound negative effect on health care.

Nicotine Dependence and Loss of Autonomy among Greek Adolescent Smokers: A Countrywide Cross-Sectional Study.

Nicotine dependence is one of the main reasons for the continuation of smoking among adolescents. Loss of autonomy (LOA) is a measure of dependence. This study is the first to investigate LOA and its determinants among Greek adolescents. In 2013, 13-to-15-year-old middle-school students were selected by multi-stage clustered sampling. LOA was evaluated with the Hooked-on-Nicotine Checklist (HONC). Multiple univariate analysis was used to assess the association between adolescent demographics, smoking habits, and loss of autonomy. Three-hundred thirty-nine current smokers responded to the questionnaire (response rate: 82.3%). Of these respondents, 51.2% were male and 88.8% reported at least one LOA symptom. The mean HONC score was 4.13/10 (95% CI: 3.82-4.45). Higher scores were negatively associated with lower smoking frequency (cumulative odds ratio (cOR): 0.240, 95% CI: 0.144-0.400) and positively associated with lower age at first cigarette (cOR: 2.29, 95% CI: 1.38-3.82). Female gender was significantly associated with the prevalence but not the degree of LOA. Overall, the prevalence and the degree of nicotine dependence among adolescent smokers in Greece is similar to other countries. Frequent smoking and initiation of smoking at a younger age are linked to nicotine dependence, although it was not possible to make causal inferences. The relationship between nicotine dependence and gender remains unclear.

Prevalence of tobacco use, exposure to secondhand smoke and knowledge on smoking cessation among students of health professions in Central Greece: a cross-sectional study.

OBJECTIVES: The aim of this study was to assess the prevalence of tobacco use and exposure to secondhand smoke among students of health professions (SHPs) and determine possible risk factors for current smoking. In addition, we sought to investigate the level of students' knowledge regarding smoking cessation. DESIGN: Cross-sectional. SETTING: Central Greece. PARTICIPANTS: A convenient sample of 822 SHP volunteers were used, composed of 365 medical students, 123 students from a biochemistry department, 71 students from a nursing department, 176 from medical laboratory department and 84 students from a veterinary medicine department. PRIMARY AND SECONDARY OUTCOME MEASURES: We investigated the prevalence of current smoking and secondhand smoke, their determinants and SHP's knowledge and attitudes regarding smoking cessation. Univariate and logistic regression statistical analysis were used in order to identify risk factors associated with current smoking. RESULTS: The prevalence of current smoking was estimated at 23.5% (95% CI 20.7% to 26.5%), while 49% of current smokers reported they wanted to quit smoking. The prevalence of current e-cigarette use was 1.2%. In addition, 96.5% (95% CI 94.9% to 97.5%) of SHP have been exposed to secondhand smoke at least 1 day per week. Logistic regression analysis showed that increasing age (p<0.001), alcohol consumption (p<0.001) and exposure to secondhand smoke in the home (p<0.001) were independent risk factors for current smoking. Notably, only 11.6% of the participants had learnt about methods to be used for smoking cessation. CONCLUSIONS: Our results underline the need for integrated tobacco control initiatives that should discourage tobacco use among SHP, promote smoke free schools of health science, and implement programs that train SHP in effective cessation-counseling techniques.

Prevalence of Electronic Cigarette Use and its Determinants among 13-to-15-Year-Old Students in Greece: Results from the 2013 Global Youth Tobacco Survey (GYTS).

Electronic cigarette use has increased over the past decade. Its potential role in smoking cessation, in addiction and as a 'gateway' to tobacco smoking is subject to intense research. This cross-sectional study, carried out in 2013, aims to present the habits of students aged 13-15 in Greece with regard to e-cigarettes and investigate potential risk factors and the relationship between e-cigarettes, tobacco smoking and other nicotine products. It is the first such study to be carried out in Greece. The survey was based on the standardized methodology of the Global Youth Tobacco Survey. All potential associations were investigated using multiple logistic regression. In total 2.8% of the 4096 participating students were current e-cigarette users and 12.3% of them were ever users. E-cigarette use was associated with male gender, being older, current use of combustible tobacco products and e-cigarette use in the family. Ever e-cigarette use, being older, female gender and higher pocket money were associated with an increased susceptibility to tobacco smoking. E-cigarette prevalence in Greece in 2013 was similar to that of other, developed countries. The smoking and vaping habits of adolescents must be monitored in order to assess trends over time and whether any policy alterations are necessary.

Prevalence and determinants of current cigarette smoking and secondhand smoking among Greek adolescents: the Global Youth Tobacco Survey (GYTS) 2013 study.

OBJECTIVES: Smoking prevalence in Greece is considered high within the European Union and the collection of evidence on tobacco use among adolescents is of vital importance in order to develop effective smoking prevention and cessation programmes. DESIGN: Cross-sectional. SETTING: Greece. PRIMARY AND SECONDARY OUTCOME MEASURES: Global Youth Tobacco Survey (GYTS) is a national representative, paper-and-pencil, cross-sectional, school-based study of students at ages 13-15 years. The survey employed a multistage cluster sample design with schools selected proportional to enrolment size. Finally, 4618/5127 students aged 13-15 years participated in the survey. The school response rate was 98.1%, the student response rate was 90.1% and the overall response rate was 88.4%. RESULTS: The prevalence of current cigarette smoking was estimated at 10.1% (10.4% in GYTS 2005) and of exposure to secondhand smoking in public places at 67.4% (94.1% in GYTS 2005). The vast majority of the adolescents (82.1%) supported the banning of smoking inside enclosed public places. Most of the current smokers (90.8%) were not prevented/refused purchase because of their age according to existing law. Multivariate analysis showed that peer influence (OR=48.32; 95% CI 36.2 to 64.48), pocket money (OR=2.63; 95% CI 1.28 to 3.41), increasing age (OR=2.35; 95% CI 1.63 to 3.39) and low educational level of father (OR=2.82; 95% CI 1.7 to 4.68) were risk factors independently associated with current cigarette smoking. CONCLUSIONS: Despite the existence of strict laws related to tobacco control, exposure to secondhand smoking among Greek students remained high even when compared with GYTS in 2005. This is likely a result of weak enforcement, what is really missing is the enforcement of the related legislation.

Design and Development of a Viral Hepatitis and HIV Infection Screening Program (Hprolipsis) for the General, Greek Roma, and Migrant Populations of Greece: Protocol for Three Cross-Sectional Health Examination Surveys.

BACKGROUND: Although infectious diseases are globally on the decline, they remain a major global public health problem. Among them, the hepatitis B virus (HBV) or hepatitis C virus (HCV) and HIV infection are of primary interest. Valid prevalence data on these infections are sparse in Greece, especially for vulnerable populations. OBJECTIVE: This study aimed to present the design and methods of Hprolipsis, an integrated viral hepatitis and HIV screening program administered to adults (≥18 years) from the general, Greek Roma, and migrant populations. Its aims were to estimate the prevalence of HBV, HCV, and HIV; assess infectious disease knowledge level; design, implement, and assess population-specific awareness actions; and offer individual counseling and referral when indicated and HBV vaccination to susceptible Roma and migrants. METHODS: Multistage, stratified, random sampling based on the 2011 Census was applied to select the general population sample, and nonprobability multistage quota sampling was used for Roma and migrant sample selection. Trained personnel made home (general population) or community (Roma and migrants) visits. Collected blood samples were tested for Hepatitis B surface Antigen, Hepatitis B core Antibody, Hepatitis B surface Antibody, Hepatitis C Antibody, and HIV 1,2 Antibody. The surveys were conducted during May 2013 and June 2016. To estimate an HCV prevalence of 1.5% with 0.3 precision, the required general population sample size was estimated to be 6000. As migrants constitute 10% of the whole Greek population, the migrant sample size was set to 600. A feasible sample size of 500 Greek Roma was set. RESULTS: In total, 6006 individuals from the general population (response rate 72%), 534 Greek Roma, and 612 migrants were recruited. Blood test results are available for 4245 individuals from the general population, 523 Roma, and 537 migrants. CONCLUSIONS: Hprolipsis is the first nationwide survey on HBV, HCV, and HIV. Its results will enhance our understanding of the health needs and disease burden of these diseases in the 3 studied populations. Its implementation provided useful recommendations for future studies, particularly in vulnerable populations. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/13578.

Nationwide Epidemiological Study of Knowledge, Attitudes, and Practices Study of Greek General Practitioners Related to Screening.

BACKGROUND: We aimed to assess general practitioners' (GPs) knowledge, attitudes, and practices (KAPs) toward screening recommendation guidelines of the United States Preventive Services Task Force (USPSTF). METHODS: The survey was conducted during a 6-month period in a stratified random sample of GPs, drawn from a national database of GPs in Greece. Participants were queried about their knowledge, attitudes, and self-reported practice patterns regarding screening in a primary care setting. Sociodemographic characteristics associated with vague screening practicing were identified using multivariable logistic regression models. RESULTS: A total of 299 participants agreed and underwent telephonic survey (response rate: 78.2%). GPs agreed on the key role of population-based screening in improving patient care, and nine out of ten reported that their performance would be improved with the adoption of computer-based support systems in clinical practice. GPs, older than 50 years of age, those who those practicing for more than 15 years and GPs working in private sector, were less likely to comply with screening recommendations. Latent class analysis revealed that male physicians and those working in public sector were more likely to comply with USPSTF recommendations. CONCLUSIONS: Our findings highlight the need of educational intervention programs for GPs in order to promote the implementation of national evidence-based screening recommendation statements in clinical practice.

Organ donation attitudes and general self-efficacy: exploratory views from a rural primary care setting.

INTRODUCTION: Behavioral determinants can enable or hinder motivation towards registration and donorship and, subsequently, action or inertia towards organ donation. Nevertheless, there is limited information about the role of self-efficacy in relation to organ donation awareness and presumed consent among individuals and their families. The aim of this study was to explore knowledge, attitudes and general self-efficacy as behavioral determinants for organ donation among rural primary care attendants, in order to tailor awareness strategies for reversing inertia within an opt-out system. METHODS: This was a prospective face-to-face survey during regularly scheduled appointments of 203 attendants at a rural primary care unit in northern Greece. Responses to a 12-item adapted 'Organ donation awareness' questionnaire measuring knowledge, attitudes and awareness were related to participants' General Self-Efficacy (GSE) Scale score. Hierarchical modelling of a multiple linear regression model was adopted with GSE score added. RESULTS: About one-third of respondents (34.0%) had discussed presumed consent with a partner, family member or friend. More than half (54.2%) were concerned that donated organs might be used without consent for other purposes, such as medical research. A total of 30% found organ donation unacceptable because of religious beliefs. Organ donation awareness was not influenced by respondents' specific characteristics, but was significantly related to the GSE score (standard β=0.155, p=0.033). CONCLUSION: Overall, organ donation perceptions among rural primary care recipients were determined by knowledge of the presumed consent procurement system, pre-conceptions, religious beliefs, altruism and GSE scores. The association of self-efficacy with raised awareness could potentially explain the gap between high intent to consent as a donor and subsequent lack of follow-up action. Further comparative research across behavioral determinants between rural/urban groups is needed in order to tailor awareness strategies suitable for an opt-out system.

Clusters of Healthcare-Associated Legionnaires' Disease in Two Hospitals of Central Greece.

Healthcare-associated Legionnaires' disease often leads to fatal respiratory tract infection among hospitalized patients. In this report, three cases of Legionnaires' disease among patients in two different hospitals (Hospital A and Hospital B) were investigated. After conducting an epidemiologic and environmental investigation, the water distribution systems (WDSs) were identified as the possible source of infection, as Legionella pneumophila serogroup 1 (Lp1) was isolated from both clinical and environmental samples. Patients received aerosol therapy with nebulizers during their hospitalization. Based on the results of the investigation, the hospitals' infection control committees reviewed their policies for Legionnaires' disease prevention and implemented control measures focusing on using sterile fluids for aerosol treatments.

Prevalence and determinants of smoking and secondhand smoke exposure in a rural population of central Greece: a cross-sectional study.

INTRODUCTION: Smoking is one of the most important risk factors for heart and lung disease and is responsible for many forms of cancer. The resulting morbidity and mortality weigh heavily upon countries with high prevalence, such as Greece. According to the Global Adult Tobacco Survey (GATS) Greece, 38.2% of Greeks aged ≥15 years, namely 51.2% of men and 25.7% of women, are smokers. Smoking is also common among the young and people of high education. Despite laws prohibiting smoking at indoor places, exposure to environmental tobacco is very high both in private and public places. The study goal was to estimate the prevalence and characteristics of smoking, the level of tobacco exposure and the factors that affect both in a rural population. METHODS: A cross-sectional household study was conducted using the GATS questionnaire in a rural borough of Thessaly, Greece. Eligible participants were permanent residents of the selected villages, aged ≥18 years and they were selected by a combination of stratified sampling with probability proportional to size, random sampling and convenience sampling. Population demographics, current smoking status and tobacco use patterns, exposure to secondhand smoke, attitudes and knowledge on smoking were recorded. Analyses were performed according to the GATS manuals using the SPSS complex samples module. RESULTS: A total of 330 adults participated in the study (168 men, 162 women). The mean age of the sample was 54.2±17.75 years (range 18.5-86.1 years). Smoking prevalence was 32.4%; 46.4% (95% confidence interval (CI) 37.8-55.3%) of men and 17.9% (95%CI 12.0-25.9%) of women were smokers. Smoking was also common among the young, people with secondary education and high school graduates. The manufactured cigarette was the most preferred tobacco product. Daily smokers consumed on average 20.6 (95%CI 17.67-23.52) cigarettes per day. Men smoked more cigarettes and started at an earlier age than women. Overall exposure to environmental tobacco smoke was high among the population. Men, individuals aged 18-24 years and 40-54 years were more exposed than their counterparts. Places where high exposure was recorded included restaurants (80.0%, 95%CI 76.0-83.5%), bars (87.8%, 95%CI 75.7-94.3%) and coffee shops (82.6%, 95%CI 68.4-91.3%). Six out of ten (62.1%, 95%CI 51.7-71.5%) workers were exposed at their workplace and nearly half were exposed on a daily basis. Prevalence of home exposure was 40.4% (95%CI 32.0-49.5%). The multivariate analysis showed that sex and age were independent predictors of current smoking status, while only sex was independently associated with exposure to secondhand smoke. CONCLUSIONS: There are very few studies studying the characteristics of smoking and tobacco exposure exclusively in rural populations in Greece, such as the present study. Both the high prevalence of smoking and the high levels of exposure to tobacco show a population at increased risk for tobacco-related disease. These call for immediate action to reduce smoking prevalence, help smokers quit and protect the health of non-smokers. The present study's conclusions provide the basis for designing local prevention programs and the baseline for monitoring of future trends in the area.

Prevalence of lung function impairment among Greek cement production workers: a cross-sectional study.

Greece is a significant cement producing country. The aim of this study was to investigate the prevalence and risk factors of lung function impairment among Greek cement workers. One hundred thirty- seven cement production workers participated in this study. In addition, 110 employees not exposed to cement dust comprised the control group. The concentration of cement total dust at workplace varied from 1.1 to 11.6 mg/m3. In only one of the measurements, the Threshold Limit Level of 10 mg/m3 has been exceeded. Cement production workers presented a higher prevalence of FEV1<80% in comparison to controls (13.9% vs. 2.7%; Chi-Square Test; p=0.002). Multivariate analysis has shown that cement production workers have recorded an almost 5 fold risk of low lung function, as expressed by FEV1<80%, in comparison to the reference population OR=4.92; 95% C.I.=1.22-12.62). Current smoking was associated with an almost 4- fold increased risk of FEV1<80% (OR=3.91;95% C.I.=1.32-11.56). In conclusion, we found a high prevalence of impaired lung function among Greek cement production workers, despite the fact that total and inhalable dust levels were below the occupational exposure limits.

Increased Frequency of Rheumatoid Arthritis and Allergic Rhinitis among Pesticide Sprayers and Associations with Pesticide Use.

Objective: The aim of this study was to identify diseases linked with the pesticide sprayer occupation and explore possible associations with exposure history data. Methods: Α cross sectional study was conducted among pesticide sprayers (n = 80) and the general population (n = 90) in Thessaly (Greece). Medical history, demographic characteristics and detailed exposure history were recorded by conducting personal interviews. Lifetime exposure indicators were calculated for several pesticide chemical subclasses. Moreover, organophosphate metabolite levels were quantified in urine samples of all participants by using gas chromatography -mass spectrometry (GC-MS). Multinomial analysis was used to determine associations between occupational pesticide exposure and diseases or disorders. Results: In the pesticide sprayers group, significantly higher frequencies for rheumatoid arthritis (RA) and allergic rhinitis were observed compared with the control group (p = 0.002 and p = 0.024 respectively). Within the pesticide sprayers group, high lifetime pesticide exposure was associated with increased risk for reporting RA (OR: 43.07 95% CI: 3.09-600.67) and allergic rhinitis (OR: 9.72 95% CI: 2.31-40.89), compared with low pesticide exposure. Exposure to organophsphate, guanidine and quinone pesticides were associated with RA while organophosphates, pyrethroids and paraquat were associated with allergic rhinitis. Despite the higher levels of certain pesticide metabolites observed among participants with rheumatoid arthritis, the differences were not statistically significant. One metabolite (diethylthiophosphate) was found to be significantly increased in allergic rhinitis cases (p = 0.037). Conclusions: The results from the current study suggest a possible association of occupational pesticide exposure with RA and allergic rhinitis that should be further investigated.

Prevalence and determinants of current and secondhand smoking in Greece: results from the Global Adult Tobacco Survey (GATS) study.

OBJECTIVES: Greece is one of the leading tobacco-producing countries in European Union, and every year over 19 000 Greeks die from tobacco-attributable diseases. The aim of the present study was to provide nationally representative estimates on current and secondhand smoking prevalence in Greece and their determinants. DESIGN: Cross-sectional. SETTING: Greece. PARTICIPANTS: A total of 4359 individuals participated in the Global Adult Tobacco Survey (GATS), a household survey of adults ≥15 years old (overall response rate 69%). They were selected through a multistage geographically clustered sampling design with face-to-face interview. PRIMARY AND SECONDARY OUTCOME MEASURES: In 2013, we investigated the prevalence of current and secondhand smoking and their determinants. Univariate and logistic regression analysis was used in order to identify possible risk factors associated with the prevalence of current and secondhand smoking. RESULTS: The prevalence of current smoking was 38.2% (95% CI 35.7% to 40.8%), and the mean number of cigarettes smoked per day was 19.8. Multivariate analysis confirmed that male gender (OR=3.24; 95% CI 2.62 to 4.00), age groups (25-39, OR=4.49; 95% CI 3.09 to 8.46 and 40-54, OR=3.51; 95% CI 1.88 to 5.87) and high school education (OR=1.97; 95% CI 1.41 to 2.74) were independently associated with the current smoking. Remarkably, responders with primary or less education had the lowest prevalence of current smoking (p<0.001). The prevalence of exposure to secondhand smoke at work, home and restaurants, was 52.3%, 65.7% and 72.2%. In total, 90.0% (95% CI 87.8% to 91.9%) of Greek population is exposed to tobacco smoke (current smoking and secondhand smoke). CONCLUSIONS: Our results revealed an extremely high prevalence of current smoking and exposure to secondhand smoke among the adult population and a positive gradient between education and current smoking. These findings are alarming and implementation of comprehensive tobacco control and prevention strategies could be impactful in fighting the tobacco epidemic in Greece.
