Prevalence of Sexually Transmitted Infections and Risk Factors Among Young People in a Public Health Center in Brazil: A Cross-Sectional Study

Prevalence of sexually transmitted infections (STIs) among first time visitors at STIs clinic in Hangzhou, China: Assessing the influence of the COVID-19 pandemic

BACKGROUND

This study assesses the prevalence of sexually transmitted infections (STIs) in first time visitors to the STIs clinic in Hangzhou, China, considering different genders, ages and symptoms. And also explores howthe COVID-19 pandemic has affected on STIs.

METHODS

From 2019 to 2023, 27,283 first time visitors were tested for nine distinct STIs, including Human Papillomavirus (HPV), Human Immunodeficiency Virus (HIV), syphilis, Herpes Simplex Virus type 2 (HSV-2), Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), and vaginal Candida.

RESULTS

Symptomatic male and female visitors showed overall STI-positive rates of 39.27% and 59.20%, respectively(p < .001). The top three pathogens in both genders were HPV (47.56% and 56.71%), UU (29.21% and 56.47%), and HSV-2 (22.41% and 52.94%). Among asymptomatic visitors, the total STI-positive rate was 36.63% in males and 52.03% in females. Age-stratified analysis revealed higher STI rates in visitors ≤ 20 or >50 years, regardless of gender and symptoms. During the COVID-19 pandemic, symptomatic visitors showed lower positive rates for HPV, HIV, syphilis, and HSV-2, while Candida, UU, CT, NG, and multiple infections increased. Among asymptomatic visitors, HPV had the lowest positive rate, while NG and multiple infections increased during the pandemic.

CONCLUSION

STI prevalence is notably high, particularly in those aged ≤ 20 and >50 years. It emphasizes the need for enhanced health education, condom use, and vaccination. The COVID-19 pandemic impacting STIs through varied factors, such as reduced sexual activity and clinical service interruption.

Improvement and exacerbation of multiple disparities in sexually transmitted infections among children and adolescents aged 6-22 years: An analysis of national surveillance data from 2013 to 2021

To investigate the progress of disparities in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), gonorrhea, and syphilis among children and adolescents aged 6-22 years in China during 2013-2021. A total of 614 325 cases data were extracted from the Chinese Information System for Infectious Diseases Control and Prevention during 2013-2021. Puberty health education data were drew from the Student Health Surveillance in 2021. Disparity patterns and average annual percentage changes (AAPCs) in sexually transmitted infections (STIs) incidence or new cases in China were examined using descriptive statistics and joinpoint regression. The incidence across 345 cities was stratified by gross domestic product (GDP). Between 2013 and 2021, there were 614 325 reported cases of HIV/AIDS, gonorrhea, and syphilis among children and adolescents aged 6-22, with an annual average incidence of 24.0967 per 100 000. The expansion of HIV/AIDS has halted, yet the surge in gonorrhea and syphilis remains notably pronounced. The ratio of male to female AIDS incidence increased from 2.75 (2.60, 2.90) to 7.13 (6.68, 7.62), but that of syphilis changed from 0.33 (0.32, 0.34) to 0.56 (0.55, 0.57). Students and out-of-school individuals aged 13-15 experienced a notably high increase in STI cases, surpassing other age groups, with an average annual percentage increase of 29.2% and 26.3%, respectively. Nonstudents consistently had a higher incidence rate than students, with an IRR reaching 31.80 (31.24, 32.37) in 2021. A noticeable clustering pattern of new cases emerged in the southeastern region of the Heihe-Tengchong line, extending inland from the coastal areas. Districts and counties with lower rates of puberty sexual health education tended to have higher average STI incidence rates. At the prefecture and city levels, there was a noticeable upward trend on average STI incidence rates in cities with per capita GDPs. Strategies to address those disparities include promoting equitable health education, and widespread sexual health education, particularly in areas with limited access to education and experiencing rapid economic development. The effectiveness of sexual health education intervention needs to be further evaluated in well-designed studies.

Adolescents' Perceptions of Sexuality: A Qualitative Study

Adolescents have a greater risk of acquiring sexually transmitted infections (STIs), which is a serious public health problem. Education is an effective strategy to improve adolescent sexual health outcomes. However, Spanish adolescents have a lack of sex education. The aim of this study was to explore the perceptions and opinions of a sample of adolescents regarding sexually transmitted infections (STIs). Photovoice is a research method that uses the search for images of everyday events with the intention of bringing about social change. An exploratory, descriptive design was used with a qualitative approach based on the Photovoice methodology. The sample consisted of 26 high school and baccalaureate students of Almería (Spain) selected through a convenience sample. The age of the participants ranged from 14 to 17 years, with a mean age of 15.31 years. Two main categories were extracted from the data analysis: 'Towards a culture of preventing STIs and promoting healthy sexual practices' and 'Adolescents' needs from their perspective'. In conclusion, numerous changes take place at the biopsychosocial level during adolescence that imply a need to explore their sexuality in depth. A lack of knowledge and a carefree attitude during sexual initiation can increase the risk of developing STIs. The study's adolescents stated that they do not have adequate sex education to acquire sufficient knowledge about sexuality and sexual health, and therefore, request that the traditional format be modified in order to achieve better results.

Herpes Simplex Virus, Human Papillomavirus, and Cervical Cancer: Overview, Relationship, and Treatment Implications

There is a significant body of research examining the role of human papillomavirus (HPV) in the pathogenesis of cervical cancer, with a particular emphasis on the oncogenic proteins E5, E6, and E7. What is less well explored, however, is the relationship between cervical cancer and herpes simplex virus (HSV). To date, studies examining the role of HSV in cervical cancer pathogenesis have yielded mixed results. While several experiments have determined that HPV/HSV-2 coinfection results in a higher risk of developing cervical cancer, others have questioned the validity of this association. However, clarifying the potential role of HSV in the pathogenesis of cervical cancer may have significant implications for both the prevention and treatment of this disease. Should this relationship be clarified, treating and preventing HSV could open another avenue with which to prevent cervical cancer. The importance of this is highlighted by the fact that, despite the creation of an effective vaccine against HPV, cervical cancer still impacts 604,000 women and is responsible for 342,000 deaths annually. This review provides an overview of HSV and HPV infections and then delves into the possible links between HPV, HSV, and cervical cancer. It concludes with a summary of preventive measures against and recent treatment advances in cervical cancer.

Global, regional, and national burdens of HIV and other sexually transmitted infections in adolescents and young adults aged 10-24 years from 1990 to 2019: a trend analysis based on the Global Burden of Disease Study 2019

BACKGROUND

Sexually transmitted infections (STIs), including HIV, are major sexual health issues among adolescents and young adults globally, but data on the burden and trends of these diseases are sparse. We aimed to assess the trends in the burden of HIV and other STIs among adolescents and young adults aged 10-24 years from 1990 to 2019 on the global, regional, and national level.

METHODS

In this trend analysis based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we reported on the number, rates per 100 000 population, and average annual percentage changes (AAPCs) of incidence and disability-adjusted life-years (DALYs) of HIV and other STIs (syphilis, chlamydia, gonorrhoea, trichomonas, and genital herpes) at the global, regional, and national level among individuals aged 10-24 years. We further analysed these global trends by age, sex, and social development index (SDI). We also used joinpoint regression analysis to identify the year with the most substantial changes in global trends.

FINDINGS

Globally, the incidence of HIV among adolescents and young adults decreased from 34·5 per 100 000 population (95% uncertainty interval [UI] 29·3 to 39·7) in 1990 to 22·7 per 100 000 population (20·3 to 25·8) in 2019, AAPC -2·6 [95% CI -3·1 to -2·0]); specific years in which HIV incidence decreased significantly were 1998, 2005, and 2014. Incidence of other STIs increased from 6986·3 per 100 000 population (95% UI 5504·8-8645·0) in 1990 to 7088·7 100 000 population (5620·1-8697) in 2019 (AAPC 0·2 [95% CI 0·1-0·3]); we found a substantial decrease in the incidence of other STIs in 2011 only. The rate of decrease in the incidence of other global STIs between 2009 and 2019 was approximately one-fifth the rate of the decrease in the global incidence of HIV for the same time period (AAPC -0·7 [95% CI -0·8 to -0·7] vs AAPC -3·4 [-3·8 to -3·1]). Regionally, sub-Saharan Africa had the highest incidence and highest DALYs from HIV and other STIs, and Oceania and Eastern Europe had the largest increase in the incidence and DALYs from HIV and other STIs between 1990 and 2019. By SDI quintile, the middle-SDI countries had the largest increase in HIV incidence between 1990 and 2019 and the DALYs from other STIs in the same period decreased in all SDI quintiles. Globally, females accounted for 278 076 (65·8%) of the 0·42 million incident HIV cases in 2019 and 68 115 077 (51·6%) of the 132·0 million incident cases of other STIs. Of all age groups, adolescents aged 10-14 years had the largest increase in the incidence of other STIs between 1990 and 2019 (from 1158·9 per 100 000 population [95% UI 857·8-1556·5] in 1990 to 1215·4 per 100 000 population [893·5-1616·1] in 2019; AAPC 0·1 [95% CI 0·1-0·2]). The individual STIs with the highest incident rates varied between age groups and sex.

INTERPRETATION

Global HIV incidence among adolescents and young adults decreased between 1990 and 2019, with significant decreases coinciding with the implementation of antiretroviral therapy and pre-exposure prophylaxis. The incidence of other STIs in this population increased over the same period and only started decreasing in 2011, at a rate of only one-fifth of the rate of decrease of HIV. Earlier sexual health education and targeted STI screening are urgently required for adolescents and young adults.

Sexual function in Brazilian female adolescents and young adults: a cross-sectional study

OBJECTIVE

The aim of this study was to investigate and compare the sexual function of Brazilian adolescents and young women who were using popular contraceptive methods.

METHODS

This cross-sectional study took place in 2012-2014 in a free family planning clinic of a tertiary teaching hospital in Brazil. Participants were female adolescents (10-19 years) and young adults (20-24 years) who were using barrier (condom) or hormonal contraceptive methods. The Female Sexual Function Index questionnaire was used to assess the sexual function in the last 4 weeks.

RESULTS

A total of 199 women (128 adolescents and 71 young adults) were included. There were no significant differences in the mean total Female Sexual Function Index scores of adolescents and young adults (26.6±5.7 versus 27.6±6.2, respectively, p=0.264). Compared to young adults, adolescents had significantly lower mean scores for orgasm (3.9±1.5 versus 4.4±1.4, p=0.020) and dyspareunia (4.4±1.6 versus 5.2±1.5, p=0.001; lower scores indicate more dyspareunia). There were no significant differences in the proportion of adolescents versus adults classified as being at risk for sexual dysfunction (38.3 versus 42.3%, p=0.651) or at risk of low desire (18.0 versus 21.1%, p=0.579).

CONCLUSION

Nearly 40% of Brazilian female adolescents and young adults are at risk for sexual dysfunctional symptoms and 19% have low desire, without significant differences between the two age groups.

[Sexual behavior and prevention of sexually transmitted infections taking the SARS-CoV-2 pandemic into account. Data from a sexual healthcare and medicine center-WIR]

Hintergrund

Anwendungsbezogene Daten zu sexueller Gesundheit und sexuellem Verhalten in unterschiedlich sexuell aktiven Populationen stehen nur begrenzt zur Verfügung, sind aber für Präventions- und Versorgungsstrategien sehr relevant. Das multisektorale Versorgungszentrum WIR – Walk In Ruhr hat aufgrund seiner Besucher*innenstruktur Zugang zu Daten aus diversen Lebenswelten.

Ziel der Arbeit

Aus verschiedenen WIR-internen Datenquellen sollen populationsbezogene Erkenntnisse zu Alter, Geschlecht, sexueller Orientierung, Sexual- und Risikoverhalten gewonnen und Bedarfe für Prävention abgeleitet werden. Einflüsse der SARS-CoV-2-Pandemie auf das Sexualverhalten sollen durch den Vergleich verschiedener Zeiträume untersucht werden.

Methoden

Ausgewertete Datenquellen sind der Onlinerisikotest für HIV und STI, die COWIR- und PrEP-Studie sowie die Immunologische Ambulanz und das Gesundheitsamt im WIR.

Ergebnis

Sexuell übertragbare Infektionen (STI) sind von 2019 auf 2020 trotz Kontaktbeschränkungen gestiegen. Generell haben junge Menschen, Männer, die Sex mit Männern, und Frauen, die Sex mit Frauen haben, ein erhöhtes STI-Risiko aufgrund der gewählten Sexualpraktiken und der Anzahl sexueller Kontakte. Eine hohe Zahl bi- und transsexueller Kontakte ist festzustellen. SARS-CoV‑2 führte zu einer Reduzierung der Sexualkontakte. Sexualpraktiken wurden weiter gelebt. Die STI-Testquote und die Behandlungsrate stiegen an.

Diskussion

Die Daten aus dem WIR belegen, dass eine junge Klientel mit aktivem Sexualleben erreicht wird. Die Ergebnisse aus Fragebögen und dem Onlinerisikotest zeigen den Zusammenhang von erhöhten positiven STI-Tests mit Sexualverhalten und sexuellen Präferenzen, weshalb spezifische Strategien zu Sexualaufklärung, Prävention, Tests und Therapien erforderlich sind.

Dating Applications, Sexual Behaviors, and Attitudes of College Students in Brazil's Legal Amazon

Although dating applications (apps) have become popular among young adults, there is a dearth of information regarding the sexual health implications among Brazilian college students. This study examined risky sexual behavior and attitudes of dating app users, based on their sex in Brazil’s Legal Amazon. Three hundred and fifty-nine students reported their sociodemographic data, dating app use, and sexual behaviors and attitudes through self-administered questionnaires. Bivariate analyses and analysis of variance (ANOVA) with Bonferroni post-hoc tests were performed. Dating app use was reported by 238 (66.3%) subjects, most of whom had an encounter and sex with a casual partner. Women frequently requested condom use. Trust in one’s partner or having repeated encounters were the main reasons for engaging in risky sexual behavior. Men had a greater number of sexual partners and less protective attitudes. Sexual health awareness by apps was not reported by 97% of women, and most of them were not tested for sexually transmitted infections. A positive attitude toward sexual health was not a predictor of safe sex. Important similarities and differences regarding risky sexual behaviors and attitudes were observed between the sexes, many of which correlated with increased sexual vulnerability during the sexual encounters arranged through the dating apps. This cross-sectional study supports efforts on sexual health promotion and sexual education implementation in the face of growing usage of apps among young adults for sexual matters.
