Background and Objectives: The aim of this study was to assess the consumption of dietary supplements (DS) among working-age residents of Lithuania from 2021 to 2023 with respect to social and demographic factors and an assessment of personal health. Materials and Methods: Using stratified sampling techniques, this study included three samples of working-age residents (1600 each year, 4800 total). Three surveys were conducted, the distribution of the respondents between groups was compared using the χ2 test. Results: The consumption of DS significantly differed each year and accounted for 78.1%, 71.6%, and 72.7% of the respondents, respectively (p < 0.05). In 2022, the prevalence of the consumption of DS was lower in the majority of social and demographic groups (p < 0.05). In 2023, it was higher among females, younger residents, and those from larger families, who suffered from COVID-19 (p < 0.05). Despite similar changes found in the consumption of DS among those who negatively assessed their health, this group showed more prevalent consumption of DS among residents with non-university education, unemployed respondents, and those with lower income (p < 0.05). Conclusions: Despite a significantly lower prevalence in the consumption of DS in 2022, it was higher again in 2023. The assessment of personal health shows different habits in the consumption of DS.

Background and Objectives: Epicardial adipose tissue (EAT) is shown to be an important factor in the development of coronary artery disease, but numerous pathophysiological mechanisms of its action are still only partially understood. There is a lack of studies on its association with different grades of essential hypertension (EH). Therefore, we aimed to evaluate the association between size of EAT depots and the risk of EH taking into account its grade. Materials and Methods: Non-obese adult patients with various cardiovascular diseases were investigated: 157 of them had essential hypertension and 101 did not. Hypertensive patients were assigned to three groups according to the grade of hypertension. EAT volume and thickness on ventricular free walls (6 locations) and grooves (5 locations) were measured using cardiac magnetic resonance imaging and compared between groups. A regression model for the prediction of EH was constructed. Results: In general, thickness (in all locations) and volume of EAT depots was greater among hypertensive patients than in normotensive (NORM) group. Mean EAT thickness in all 11 locations and EAT volume were lower in NORM than in grade 1 hypertension group; similarly, EAT volume was lower in grade 1 than in grade 2 hypertension group. EAT accumulation did not differ between grade 2 and severe hypertension groups. EAT volume, dyslipidaemia status, body mass index, and age were independent predictors for EH in regression model. Conclusions: EAT accumulation is larger among hypertensive than normotensive individuals. Measurement of EAT depots could be beneficial for identification of hypertensive patients and prediction of hypertension severity. Full article

Background and objective: For athletes, the main purpose of nutrition is to ensure the compensation of increased energy consumption and the need for nutrients in the athlete's body, thereby enabling maximum adaptation to physical loads. The aim of this study was to determine the habits of highly trained endurance athletes depending on sports type, sex and age in order to improve the planning and management of the training of athletes using targeted measures.
Materials and methods: In 2009–2012, the dietary habits of 146 endurance athletes were analyzed. The actual diet of Lithuania endurance athletes was investigated using a 24-h dietary survey method. Data on the athletes' actual diet were collected for the previous day.
Results: It was found that 80.8% of endurance athletes used lower-than-recommended amounts of carbohydrates in their diet, and more than 70% of athletes used higher-than- recommended levels of fat, saturated fatty acids, and cholesterol. The diet of female athletes was low in carbohydrates, dietary fiber, protein, omega-3 fatty acids, B vitamins, potassium, calcium, phosphorus, iron, manganese, and zinc. Athletes aged 14–18 years tended to consume quantities of protein that were either lower than recommended or excessive.
Conclusions: The diet of highly trained endurance athletes does not fully meet their requirements and in this situation cannot ensure maximum adaptation to very intense and/or long-duration physical loads. The diet of highly trained endurance athletes must be optimized, adjusted and individualized. Particular attention should be focused on female athletes. Full article

The aim of this study was to estimate and assess the prevalence of problem drug use in Lithuania.
Materials and Methods
. The capture-recapture method was used to estimate the prevalence of problem drug use. For the study, the data concerning problem drug users were collected from the databases of health care and law enforcement institutions. The target group consisted of permanent users (aged 15–64 years) of heroin and other opioids and/or a combination of drugs.
Results. In Lithuania, 431 monitored problem drug users were identifi ed in 2005, 482 in 2006, and 447 in 2007. The male-to-female ratio among the monitored problem drug users was 6:1 in 2006 and 4:1 in 2005 and 2007. The mean age of the monitored problem drug users was 26.8 years in 2005, 27.6 years in 2006, and 28.0 years in 2007. In total, 5699 problem drug users were identified (95% CI, 5552 to 5849) in 2005, 5800 (95% CI, 5652 to 5951) in 2006, and 5458 (95% CI, 5314 to 5605) in 2007. According to the gathered data, the prevalence of problem drug use was 2.3 cases per 1000 Lithuanian population aged 15–64 years in 2005, 2.5 in 2006, and 2.4 in 2007.
Conclusions
. The study showed one of the lowest prevalence of problem drug use in Lithuania as in Germany, the Netherlands, Greece, and Cyprus. In 2005–2007, problem drug users were mainly young men of employable age in Lithuania. Full article
