Epidemiology and determinants of reemerging bacterial sexually transmitted infections (STIs) and emerging STIs in Europe.

In this scoping review, we offer a comprehensive understanding of the current and recent epidemiology, challenges, and emerging issues related to bacterial sexually transmitted infections (STIs) in the WHO European Region. We endeavour in collating data from both EU/EEA and non- EU/EEA countries, thereby giving a complete picture of the region which highlights the higher notification rates in Northern and Western countries than other regions, likely due to differences in testing, access to testing, and surveillance capacity. We provide an up-to-date review on the current knowledge of determinants and persistent inequities in key populations as well as the use of molecular epidemiology for identifying transmission networks in gonorrhoea and syphilis, and detecting chlamydia mutations that evade molecular diagnosis. Finally, we explore the emerging STIs in the region and the evolving transmission routes of food and waterborne diseases into sexual transmission. Our findings call for harmonized STI surveillance systems, proactive strategies, and policies to address social factors, and staying vigilant for emerging STIs.

Monitoring health and health behaviors among adolescents in Central Catalonia: DESKcohort protocol.

The objective of the prospective cohort study (the DESKcohort project) is to describe and monitor health, health behaviors, and their related factors among 12 and 19-year-old adolescents schooled at centers of Compulsory Secondary Education or post-compulsory secondary education in Central Catalonia, considering social determinants of health. The DESKcohort survey is administered biannually between the months of October and June, and the project has been running for three years. We have interviewed 7319 and 9265 adolescents in the academic years 2019/20 and 2021/22, respectively. They responded a questionnaire created by a committee of experts, that included the following variables: sociodemographic factors, physical and mental health, food, physical activity, leisure and mobility, substance use, interpersonal relationships, sexuality, screen use and digital entertainment, and gambling. The results are presented to educational centers, county councils, municipalities, and health and third sector entities to plan, implement, and evaluate prevention and health promotion actions that address the identified needs.

Gender inequalities in the prevalence of low mood and related factors in schooled adolescents during the 2019-2020 school year: DESKcohort project.

BACKGROUND: Mood disorders are the second most prevalent mental disorders in childhood and adolescence. Many undiagnosed people manifest subthreshold symptoms, like low mood, and present worse prognoses than asymptomatic healthy subjects. The aim of this study was to estimate the prevalence of low mood, gender inequalities, and associated factors, in 12- to 18-year-old adolescents in the rural and medium-sized urban areas of Central Catalonia during the 2019-2020 academic year. METHODS: Cross-sectional study with data from a cohort of high-schooled students (2019-2020), with a convenience sample of 6428 adolescents from the Central region of Catalonia (48.3 % boys and 51.7 % girls). Prevalence of low mood was estimated by gender and exposure variables, and ratios were obtained using Poisson regression models, adjusting for several exposure variables one by one, and for all of them jointly. RESULTS: The prevalence of low mood was 18.6 %, with statistically significant differences between genders (11.6 %, 95 % CI: 10.5-12.8 in boys and 25.1 %, 95 % CI: 23.7-26.6 in girls). Being an immigrant, dieting, and daily tobacco smoking were only associated with low mood in girls, whereas risky alcohol consumption was only associated in boys. Sexual violence was found to account for 36.2 % of low mood problems in girls. LIMITATIONS: The main limitation of the study is its cross-sectional design, which means that no casual relationships can be extracted of this study. CONCLUSIONS: The prevalence of low mood varies between the sexes, highlighting the importance of developing gender-specific interventions to reduce its incidence in young people, considering the factors associated with this condition.

Chemsex in Barcelona: A qualitative study of factors associated with the practice, the perception of the impact on health and prevention needs. / Chemsex en Barcelona: Estudio cualitativo sobre factores asociados a la práctica, percepción del impacto en salud y necesidades de prevención.

Chemsex is defined as use of psychoactive drugs with the aim of having sexual relations between gay men, bisexuals and men who have sex with men for a long period of time. To study this phenomenon, this qualitative descriptive study was proposed with the objective of describing the practice of chemsex from the perspective of users, to determine the main factors associated with its practice, the perception of the impact on their health and to establish prevention needs. Data were obtained using conversational techniques: 12 semi-structured interviews and 3 focus groups. The purposive sample was made up of GBMSM with a mean age of 40.1 years, 78% born in Spain, and 68% with completed university studies. The qualitative analysis focused on three thematic areas: factors associated with the practice of chemsex, the impact of chemsex on health, and prevention and risk reduction needs. It is concluded that the practice of chemsex should be understood as multifactorial and multicausal, associated with the sociocultural context. Sexual satisfaction, increased libido and the search for more intense pleasure are identified as key factors among people who practice it. These men are still scared of being judged, even by specialists who may lack knowledge or training. A reanalysis and rethinking of the interventions and policies directed towards this population is necessary, putting the focus of action on shared decision-making, self-care, cultural competence and the humanization of care.

El chemsex se define como el uso de drogas psicoactivas con el objetivo de mantener relaciones sexuales entre hombres gay, bisexuales y otros hombres que tienen sexo con hombres (GBHSH), por un largo periodo de tiempo. El objetivo de este estudio cualitativo exploratorio es describir la práctica del chemsex desde la perspectiva de los usuarios, determinar los principales factores asociados a su práctica, la percepción del impacto en su salud y establecer necesidades de prevención. Se obtuvieron los datos mediante técnicas conversacionales: 12 entrevistas semiestructuradas y 3 grupos focales. El análisis cualitativo se centró en tres áreas temáticas: factores asociados a la práctica de chemsex, impacto del chemsex en la salud y necesidades prevención y reducción de riesgos. La muestra intencionada fue conformada por hombres GBHSH con una edad media de 40,1 años, 78% nacidos en España, y 68% con estudios universitarios finalizados. Los resultados del estudio ponen de manifiesto que la práctica de chemsex debe comprenderse como multifactorial y multicausal, y asociada al contexto sociocultural. La satisfacción sexual, del aumento de la libido y de la búsqueda de placer más intenso se identifican como factores clave entre las personas que lo practican. Sigue existiendo miedo en estos hombres a ser juzgados, incluso por los especialistas que pueden carecer de conocimiento o formación. Es necesario un reanálisis y replanteamiento de las intervenciones y políticas dirigidas hacia esta población, poniendo el foco de acción en la toma de decisiones compartidas, el autocuidado, la competencia cultural y la humanización del cuidado.

Linked factors to access to sexual health checkups of female sex workers in the metropolitan region of Chile.

OBJECTIVES: To describe and compare the profile of female sex workers (FSWs) that access or do not access sexual health checkups (SHC). The research question was what are the factors linked to access to SHC for FSWs in the metropolitan region (RM) of Chile? METHODS: A cross-sectional study was conducted in the RM with FSWs over the age of 18. A sample of 370 FSWs was selected by using the time-location sampling method in closed venues and at street-level locations. A survey was applied, validated, and included clinical-epidemiological, behavioral and socio-demographic variables. RESULTS: 38.6% (n = 140) of FSWs that answered the question never used SHC and 37.6% (n = 84) received checkups in a specialized health center for FSWs. FSWs with no SHC were younger, prone to have more group sex, preferably with occasional or no stable partner, and did not know where to get an HIV test. CONCLUSIONS: FSWs have had uncertain access to sexual health controls. FSWs with no SHC and young FSWs presented higher-risk behaviors.

Undiagnosed HIV and Hepatitis C infection in people who inject drugs: From new evidence to better practice.

BACKGROUND: The objective of this study was to estimate the proportion of undiagnosed HIV or Hepatitis C virus (HCV) infection and to assess the risk factors associated with an undiagnosed infection. METHODS: A questionnaire was distributed among people who inject drugs (PWID) in harm reduction centres in Catalonia, Spain 2008-2012 (n=2243). Self-report of HIV and HCV was compared to oral fluid tests to calculate the proportion of undiagnosed infection. Associations of undiagnosed HIV and HCV with age, origin, risk and protective factors of infection and services use were calculated using a Poisson regression model with robust variance. RESULTS: The sensitivity of HIV self-report was 78.5% (75.2%-81.5%) and of HCV was 81.2% (79.1%-83.2%), being lower in younger and foreign-born PWID. Specificity for HCV was 55.9% (51.6%-60.1%). PWID who engaged in infection risk behaviors had lower risk of being undiagnosed. Being foreign-born and younger increased the risk of undiagnosed infection. PWID who had not accessed medical care in the last 6months had 1.46 (1.10-1.93) times more risk of undiagnosed HIV and 1.37 (1.11-1.70) times more risk of undiagnosed HCV. CONCLUSION: Outreach programmes are essential to provide PWID, specially foreign-born and younger PIWD, access to HIV and HCV test.
