RESUMO
OBJECTIVES: The study aimed to investigate the use of electronic cigarettes (EC) among medical students, their knowledge and beliefs (opinion about harmfulness and addiction potential) on ECs, perceptions of the risk, as well as to assess the type of education and cessation training they received during their study at Faculty of Medicine, Comenius University in Bratislava, Slovakia. METHODS: This cross-sectional, anonymous online e-mailed survey was conducted among medical students via the Study Department by sending e-mails containing the survey link. Participants completed the online questionnaire adapted from the American Survey on Tobacco and Alternative Tobacco Products. It included questions about the personal use of EC, perceptions about the harms and their role in disease causation, education and cessation training, and practices related to conventional cigarettes (CC), EC, and alternative tobacco products (ATP). The e-mailed questionnaire filled in 577 medical students (71.9% women) from Comenius University in Bratislava, the average age was 23 ± 2 years. The sample comprised 486 (84.2%) Slovak and 91 (15.8%) foreign students. The data were analysed using the Statistical Package for Social Science (SPSS) version 25. RESULTS: There were 385 (66.7%) non-smokers, 111 (19.3%) ex-smokers and 81 (14%) current smokers in the study sample. EC currently use 13.5% of medical students, with a statistically significant intersexual difference (22.2% males vs. 10.12% females; OR = 2.53, 95% CI: 1.55-4.13), more foreign students than Slovak students (24.2% vs. 11.52%; OR = 2.44, 95% CI: 1.41-4.26), more smokers of conventional cigarettes than non-smokers (46.9% vs. 8.06%; OR = 10.07, 95% CI: 5.85-17.34). EC seems to be less harmful to 59.97% of students, mostly in the age group ≤ 24 (61.76% vs. 51.49%; OR = 1.46, 95% CI: 1.03-2.07), 41.25% of students consider EC to be less addictive, 55.6% think they do not get enough education on EC during their medical study. CONCLUSION: The results overall show the high consumption of tobacco products and the lack of knowledge and awareness among medical students, future health care providers. In health promotion and disease prevention, they should serve as a model for their patients and for the general public as well. Our study emphasizes the need for intervention in this field at medical faculties and for support of further monitoring in Slovakia and other countries and draws attention to the ongoing lack of EC regulation.

Objective: This study investigated the effect of a single administration of dark or milk chocolate on blood pressure (BP), heart rate (HR), and double product (DP) in young healthy women at rest and during acute mental stress.Method: Measurements consisted of anthropometry, BP, and HR. Mean arterial BP (MAP) and DP were computed. The relative reactivity of individual variables was quantified as to their percentage change during the rest or test of mental arithmetic (MA) with respect to the respective baseline value. All subjects underwent two tests of MA-one before chocolate administration and the second one 2 hours after chocolate (1 mg/g of body weight) ingestion.Results: Two hours after ingestion at rest, dark chocolate administration resulted in a significant increase in relative values of systolic BP and DP by 5.1% ± 1.4% and 13.7% ± 3.2%, respectively, compared to the responses in the milk chocolate group (-2.4% ± 1.6% and 0.6% ± 3.4%, respectively, p < 0.04 for both comparisons) without changes in diastolic BP, HR, and MAP. During MA-induced acute stress, the relative magnitude of the reactivity of diastolic BP, HR, MAP, and DP decreased by about 10, 16, 8, and 23 percentage points, respectively, 2 hours after ingestion of dark chocolate compared to the relative reactivity determined before dark chocolate ingestion. Milk chocolate failed to affect any of the above-mentioned parameters at rest or during stress.Conclusions: The single oral intake of 85% dark chocolate increased relative values of systolic BP and DP at rest but buffered the reactivity of diastolic BP, HR, MAP, and DP during mental stress, which was not found after ingestion of milk chocolate. Thus, dark chocolate might have a beneficial effect during acute stress due to its ability to buffer cardiovascular reactivity in young healthy women.

OBJECTIVE: Acrylamide is a toxic compound found in occupational and non-occupational environment. It originates from industrial use, technological processes in construction as well as food production, water purification, and laboratory use. Adverse effects including neurotoxicity, probably carcinogenicity, genotoxicity, teratogenicity, and reproductive toxicity were reported in many studies. Our study is focused on acrylamide content in selected food products in the Czech Republic. METHOD: In this study, we determined acrylamide content in selected samples of commonly consumed food products (potato chips, biscuits, popcorn, corn flakes, breakfast cereals, and baked muesli). RESULTS: The concentration of acrylamide in most samples of potato chips, biscuits and popcorn exceeded the benchmark limits. The acrylamide content in samples of potato chips from one manufacturer in 4 cases out of 5 analysed samples exceeded benchmark limit. On the other hand, no corn flakes sample acrylamide content from the same manufacture exceeded the benchmark limit. With 20 of all analysed samples exceeding the benchmark levels for acrylamide, it can be concluded that 47.6% of samples did not comply with the benchmark level. CONCLUSION: Dietary intake of frequently consumed food products with the acrylamide content exceeding the recommended comparative value could have adverse effects on the human health. Our study confirmed high amount of acrylamide in some selected food samples. The reduction of dietary burden with acrylamide is possible by complying with the correct technological principles in food preparation.

To determine demographic, reproductive, and maternal dietary factors that predict perfluoroalkyl substance (PFAS) concentrations in breast milk, we measured perfluorooctane sulfonic (PFOS) and perfluorooctanoic acid (PFOA) concentrations, using liquid chromatography-mass spectrometry, in 184 colostrum samples collected from women participating in a cohort study in Eastern Slovakia between 2002 and 2004. During their hospital delivery stay, mothers completed a food frequency questionnaire, and demographic and reproductive data were also collected. PFOS and PFOA predictors were identified by optimizing multiple linear regression models using Akaike's information criterion (AIC). The geometric mean concentration in colostrum was 35.3 pg/mL for PFOS and 32.8 pg/mL for PFOA. In multivariable models, parous women had 40% lower PFOS (95% CI: -56 to -17%) and 40% lower PFOA (95% CI: -54 to -23%) concentrations compared with nulliparous women. Moreover, fresh/frozen fish consumption, longer birth intervals, and Slovak ethnicity were associated with higher PFOS and PFOA concentrations in colostrum. These results will help guide the design of future epidemiologic studies examining milk PFAS concentrations in relation to health end points in children.

INTRODUCTION: Quality of life (QoL) has been acknowledged as a fundamental concept in the field of health and is favorably improved by physical activity (PA). This systematic review aims to assess the benefits and harms of different types of PA to improve health-related QoL in both community-dwelling and diseased older adults to provide a recommendation for the minimum amount of PA needed to obtain measurable QoL benefits. METHODS AND ANALYSIS: We will search MEDLINE, Cochrane Central Register of Controlled Trials, CINHAL, Epistemonikos, Web of Science and gray literature. Randomized controlled trials enrolling healthy or diseased older adults aged > 65 years, providing any kind of physical activity intervention and having quality of life as an outcome will be included. There will be no language restriction. Two independent reviewers will screen the papers, and a third reviewer will resolve the conflicts. The quality of the included studies will be assessed through the Risk of Bias 2.0 tool. Finally, data will be extracted to create proper meta-analyses of comparisons between the different kinds of physical activity interventions or to control groups. ETHICS AND DISSEMINATION: This review does not require approval from the Ethics Committee. The results will be disseminated in peer-reviewed journals and at international conferences; moreover, the findings will be shared on social media using an accessible language.

This study aimed to determine the factors associated with the avoidance of dental preventive care in high school students and their parents in the framework of The Youth and Parents Risk Factor Behavior Survey in Slovakia, the ongoing cross-sectional school-based survey of students and their parents or legal representatives. The data were collected using two separate standardized questionnaires: (i) the questionnaire for students (n = 515) and (ii) the questionnaire for parents (n = 681). The study group included 57 high school students (54.4% males) who did not visit the dentist for preventive care in the previous year. The control group included 458 students (35.8% males) who visited a dentist for preventive care at least once in the previous year. A significantly higher number of males (54.4%), older adolescents, and young adults (21.8%; 20.0%) were not visiting dental preventive care regularly. Incomplete family (56.1%), stressful situations at home (17.5%), and feeling unwell were the factors contributing to the avoidance of dental preventive care. More than 34.5% of adolescents and young adults were not visiting either dental preventive care or pediatric preventive care (adjusted odds ratio (AOR) = 5.14; 95% confidence interval (CI) = 2.40, 10.99). Children of divorced mothers and mothers with household income lower than EUR 900 had significantly higher dental care avoidance in bivariate analysis. A significantly higher percentage of fathers from the exposed group were not visiting dental preventive care regularly (47.8%, p < 0.05). The results of the study can be used as an educational intervention step focusing on the parental influence on adolescent and young adults' behavior and as a challenge for the improvement of dental preventive care in older adolescents and young adults.

The prevalence of cardiometabolic risk factors has increased in Slovakian adolescents as a result of serious lifestyle changes. This cross-sectional study aimed to assess the prevalence of insulin resistance (IR) and the associations with cardiometabolic and selected lifestyle risk factors in a sample of Slovak adolescents. In total, 2629 adolescents (45.8% males) aged between 14 and 18 years were examined in the study. Anthropometric parameters, blood pressure (BP), and resting heart rate were measured; fasting venous blood samples were analyzed; and homeostasis model assessment (HOMA)-insulin resistance (IR) was calculated. For statistical data processing, the methods of descriptive and analytical statistics for normal and skewed distribution of variables were used. The mean HOMA-IR was 2.45 ± 1.91, without a significant sex differences. IR (cut-off point for HOMA-IR = 3.16) was detected in 18.6% of adolescents (19.8% males, 17.6% females). IR was strongly associated with overweight/obesity (especially central) and with almost all monitored cardiometabolic factors, except for total cholesterol (TC) and systolic BP in females. The multivariate model selected variables such as low level of physical fitness, insufficient physical activity, breakfast skipping, a small number of daily meals, frequent consumption of sweetened beverages, and low educational level of fathers as significant risk factors of IR in adolescents. Recognizing the main lifestyle risk factors and early IR identification is important in terms of the performance of preventive strategies. Weight reduction, regular physical activity, and healthy eating habits can improve insulin sensitivity and decrease the incidence of metabolic syndrome, type 2 diabetes, and cardiovascular disease (CVD).

PURPOSE: Social noise exposure is currently an emerging problem in adolescents and young adults. Various leisure time activities may be responsible for hearing impairment (temporary or permanent hearing threshold shift or hearing loss). The study aimed to quantify environmental noise from various sources-voluntary (social) noise (personal music players (PMPs), high-intensity noise exposure events), and road traffic noise and to detect hearing disorders in relation to individual listening to PMPs in the sample of young adults living and studying in Bratislava, the capital city of Slovakia. METHODS: The study included 1003 university students (306 men and 697 women, average age 23.1 ± 2) living in Bratislava for 4 or more years; 347 lived in the student housing facility exposed to road traffic noise (LAeq = 67.6 dB) and 656 in the control one (LAeq = 53.4 dB). Respondents completed a validated ICBEN 5-grade scale "noise annoyance questionnaire". In the exposed group a significant source of annoyance was road traffic noise (p < 0.001), noise from entertainment facilities (p < 0.001), industrial noise (p < 0.001), and noise from neighboring flats (p = 0.003). The exposure to PMPs was objectified by the conversion of the subjective evaluation of the volume setting and duration. With the cooperation of the Ear, Nose and Throat (ENT)specialist, we arranged audiometric examinations on the pilot sample of 41 volunteers. RESULTS: From the total sample of respondents, 79.2% reported the use of a PMP in the course of the last week, and the average time was 285 minutes. There was a significant difference in PMP use between the road traffic noise-exposed (85.6%) and the control group (75.8%) (p = 0.01). Among PMP users 30.7% exceeded the lower action value (LAV) for industry (LAeq,8h = 80 dB). On a pilot sample of volunteers (n = 41), audiometry testing was performed indicating a hearing threshold shift at higher frequencies in 22% of subjects. CONCLUSIONS: The results of the study on a sample of young healthy individuals showed the importance of exposure to social noise as well as to road traffic noise and the need for prevention and intervention.

Environmental tobacco smoke (ETS) exposure has been shown in general as a major environmental risk factor and deserves attention in vulnerable population groups. The aim of the project is to analyze the relationships among the ETS and behavior and health in 6−15-year-old children in Slovakia. The status of physical and mental health of children in relation to exposure to tobacco smoke was examined in a representative group of 1478 school children. The methods used, included anonymous questionnaires filled in by parents, Columbia Impairment Scale (CIS), Behavior Problem Index (BPI) and anthropometry. The prevalence of ETS exposure is the highest in the capital (27%) and southern cities. A significant association was found between ETS and age, socio-economic status, incompleteness of the family, level of mother’s education and a higher prevalence of respiratory diseases (26.7%). The relationships of ETS with emotional (CIS scores ≥ 16) and behavioral functions (BPI score ≥ 14) were significant in children exposed to mother’s or father’s smoking at home. In the multivariate analysis these associations were not significant; the factors such as income and completeness of the family were dominant. The results showed mostly the predominant impact of social factors on the physical and mental health status of Slovak school children.

Environmental tobacco smoke (ETS) is one of the greatest and the most frequent environmental toxic exposures presenting a high risk to children and to their mothers as well. The aim of the study was to find determinants of the household ETS in the sample of pregnant women living in the household with smokers and to assess their physical and mental health. The survey was distributed to women being seen for follow-up at the obstetric/gynecology departments in hospitals and at gynecological out-patient departments in Bratislava, Slovakia. The medical outcomes short form-12 (SF-12) was included to quantify the mental and physical health of mothers. From the total sample of 617 women, 35.5% (219) were pregnant, 88.6% of them (194) non-smokers, 27.8% (54) lived with a smoking partner, the average mental component summary (MCS) score was 50.8±9.1 and physical component summary (PCS) score was 41.6±10.3. The average age was 31.3±5.1 years. In the sample of 309 non-pregnant non-smoking mothers 23% (71) lived with a smoking partner; the average age was 31.7±4.8 years. The average PCS score was 47.8±8.7 and MCS score 49.1±9. Non-smoking, pregnant women living with a smoker have fewer years of education (p=0.0003) and lower MCS scores (48.50±9.8) (p=0.03). Non-smoking, non-pregnant women living with a smoker are older (p=0.0042), with lower income (p=0.0145), have fewer years of education (p=0.002) and lower PCS score (45±9.1) (p=0.0056). Multivariate analyses revealed the decrease of MCS score in pregnant women and the decrease of PCS score in non-pregnant women living with a smoker. Our results show that living with a smoker is independently associated with worse physical and mental health in a selected sample of Slovak women, which represents an important argument for intervention in families.
