Background: Since 2020, there has been a significant increase in sexually transmitted infections (STIs), especially in young people, and these include syphilis, gonorrhea, chlamydia, and lymphogranuloma venereum, which are often asymptomatic but with the potential for transmission. In addition, certain risk behaviors, such as the use of dating apps, pornography, and substance use, reduce adherence to barrier methods, especially in men, thus facilitating the spread of these infections. Methods: This observational, cross-sectional study aimed to explore the relationship between the use of dating apps, drug and pornographic material consumption, and STI history in university students of the health sciences. Results: The sample consisted of 730 participants. The results indicated that individuals who identified as gay, lesbian, or bisexual reported significantly higher rates of dating app use, drug use, and pornography consumption compared to those who identified as heterosexual. Also, these groups showed lower adherence to contraceptive and protective methods. A statistical analysis revealed a relationship between the use of dating apps and increased sexual risk behaviors, suggesting that the accessibility of these platforms could influence the frequency and type of sexual contact. Conclusions: The increase in the prevalence of STIs in recent years has highlighted the urgency of strengthening prevention and sexual health promotion strategies, especially in young and high-risk populations. This study emphasizes the need for early and targeted interventions in high-risk groups to reduce the incidence of STIs and promote responsible sexual health practices.

(1) Background: The rise of online health resources and AI has reshaped the diagnosis and treatment of disease, altering the relationship between patients and healthcare professionals and encouraging self-medication. However, questionnaires validated in the literature on self-medication seem to lack questions on the possible causes that induce such behaviors, including items that explore trust toward websites and artificial intelligence. The aim of this study is to design and validate the content of a questionnaire designed to assess self-medication in health professionals, delving into the underlying etiologies, the pharmacological categories involved and the degree of confidence placed in clinical assessments derived from AI tools. (2) Methods: Validation study of the content of an instrument consisting of two phases: 1. The content validation phase involved evaluation by a selected group of health experts, who, using a Likert-type scale, analyzed the clarity, coherence and relevance of the items. 2. Pilot study of health professionals who have indicated the practice of self-administration of medications. (3) Results: In the first phase of the study, the experts considered most of the questionnaire items to be clear, representative and consistent with the construct to be measured. In its second phase, the preliminary results of our pilot study suggest a significant trend toward self-medication among healthcare workers, along with a strong inclination to use online resources to search for health-related information. (4) Conclusions: The development of a validated instrument to measure the influence of the different causes that lead healthcare personnel to practice self-medication, guaranteeing validity and efficacy, allows us to establish strategies to reduce this growing problem.

Previous research suggests that certain personality traits, such as extraversion and openness, may be associated with sexual risk behaviors (SRB). Exploring psychological and social factors is critical to guide effective sexual health promotion. Background/Objectives: To examine the associations between sociodemographic characteristics, personality traits, sexual attitudes, and risky sexual behaviors among health science students. Methods: A cross-sectional study was conducted with 730 health science students (median age: 21 years, IQR: 20–22 years) using validated questionnaires on personality (BPQ), sexual attitudes (BSAS), and sociodemographic factors. Non-parametric tests and logistic regressions were performed. Results: The results highlight significant differences in sexual attitudes based on sociodemographic characteristics, such as sexual orientation, type of relationship and cohabitation. High levels of pornography consumption are associated with drug use and greater permissiveness. A relationship was established between condom use and openness and intellect. Drug use scored high on extraversion and permissiveness. In relation to the use of dating apps, a positive relationship was found with permissiveness and substance use. Conclusions: The findings reveal a relationship between personality, sociodemographic characteristics, and risky behaviors, underscoring the need for tailored strategies in sexual health education for young adults.
