Background: This cross-sectional study aimed to assess the correlation between subjective oral health status and mental health in a group of university students in Serbia. Methods: The study included 948 students, aged between 18 and 27, from the Faculty of Medical Sciences, University of Kragujevac, Serbia, and was conducted in 2020. The World Health Organization’s Oral Health Questionnaire for Adults was utilized to evaluate the respondents’ self-perceived oral health and oral hygiene practices. The existence of depressive symptoms was evaluated using the Beck Depression Inventory-II (BDI-II), and the Zung self-rating anxiety scale (SAS) was used for determining anxiety symptoms. Results: It is observed that 28.9% of respondents exhibit symptoms of depression and 42.3% showed symptoms of anxiety. Results show that students with severe depression and anxiety symptoms very often reported lower self-perceived oral health and oral health problems. Although the nature of this relationship has not been thoroughly evaluated, several studies have shown a mutually dependent connection between oral health and mental health. Conclusions: The results suggest that some aspects of oral health are associated with higher risks of developing symptoms of depression or anxiety, and vice versa.

Objectives: This cross-sectional analytical study explores the predictors of the healthcare utilization in the adult population with cardiovascular diseases.Methodology: The research was carried out as part of the fourth Serbian National Health Survey, in the period from October to December 2019, as a descriptive, cross-sectional analytical study and included the population of cardiovascular patients (N = 4,712) aged over 20 years; Descriptive and inferential statistical methods, including percentage-based structure indicators, Chi-square (χ2) tests for categorical variable differences, and prevalence ratio for examining relationships between dependent and independent variables, were used in the data analysis.Results: The analysis identified several significant contributors to cardiovascular healthcare utilization, emphasizing distinct and overlapping factors that impact various types of healthcare use. The chi-square test had shown that predominantly, each form of healthcare utilization was most prevalent among the 60–69 age group (general practitioner visits: 33.9%, specialist visits: 33.1%, hospitalization: 31.4%, p < 0.001). Self-assessment of general health (bad/very bad) and the presence of multiple chronic conditions (multimorbidity) were positively associated with general practitioner (PR = 1.037(1.001–1.075); p = 0.044, PR = 1.077(1.039–1.117); p < 0.001), specialist visits (PR = 1.381(1.281–1.490); p < 0.001, PR = 1.279(1.181–1.385); p < 0.001) and hospitalization (PR = 4.346(3.272–5.772); p < 0.001, PR = 2.018(1.517–2.685); p < 0.001).Conclusion: Sociodemographic, socioeconomic factors and some aspects of health status have a significant impact on the cardiovascular healthcare, thereby precise recommendations for facilitating appropriate healthcare utilization should be established. A top priority for academics, physicians and public health specialists is to keep emphasizing the significance of sociodemographic determinants in lowering cardiovascular complications, as well as strengthening cardiovascular healthcare.

Adolescence and young adulthood are critical periods for sexual initiation with implications for lifelong sexual and reproductive health. This study assessed the prevalence of sexual activity and risky sexual behavior among individuals aged 15–24 years in Serbia and examined their sociodemographic, health-related, and behavioral correlates. A nationwide cross-sectional study used data from the 2019 Serbian National Health Survey (EHIS-wave 3). The final analytical sample included 777 participants aged 15–24 years. Sexual intercourse experience was analyzed as the primary outcome, while risky sexual behavior, defined as the presence of at least one prespecified high-risk sexual practice, was assessed as a composite outcome among sexually active respondents. Associations were examined using chi-square tests and multivariable logistic regression. Overall, 51.6% of participants reported sexual intercourse experience, and 20.9% were classified as having risky sexual behavior. Sexual activity was significantly associated with age, marital status, employment, smoking, and alcohol consumption (p < 0.05). In multivariable analysis, age group and marital status remained significant independent correlates of risky sexual behavior. Among sexually active participants, risky sexual behavior was significantly associated with age group and marital status in the adjusted model, whereas sex, smoking, alcohol consumption, education level, and employment status were not statistically significant predictors. HIV-related knowledge was high (84.2%) but was not associated with risky sexual behavior. Conclusions: Sexual activity and risky sexual behavior are common among young people in Serbia and are significantly associated with sociodemographic characteristics, particularly age and marital status. The findings highlight the need for targeted, age-appropriate, and behaviorally oriented sexual and reproductive health interventions that address broader sociodemographic and lifestyle determinants of sexual risk.
