IntroductionIn Texas, the adolescent birth rate is higher than the national average and STIs have steadily increased over the last decade. Sex education is not mandated in Texas and the majority of public schools provide an abstinence-based sex education. Comprehensive sexuality education (CSE) programs are widely endorsed by national and global health organizations and research has shown that they are more effective in reducing poor sexual health outcomes than abstinence-based programs. The purpose of this study is to identify barriers and facilitators to implementing CSE at local and state levels in Texas.MethodsQualitative study design consisting of ten semi-structured interviews with eleven key informants (n = 11) conducted in 2021.ResultsThree barriers- ideological opposition to CSE, discrimination against LGBTQ+ people, myths and misconceptions about CSE- and two facilitators- champions, collaboration with community stakeholders- to implementing CSE policy were identified.ConclusionStudy findings provide insight into the opposition faced by sex education advocates, which often stems from myths and misperceptions of CSE content and the stigmatization of sexual and gender minoritized groups. Parents, youth, medical professionals, and academic researchers are instrumental in dispelling sex education myths and misperceptions and engaging with community stakeholders.

ABSTRACT: The provision of Sexuality Education in schools can significantly contribute to the reduction of violence motivated by issues related to gender and sexuality. This Sexuality Education needs to go beyond purely biological issues, addressing several other themes, such as body, pleasure, consent, and violence in addition to more obvious issues of gender, sexuality and diversity. However, in order to carry it out, teachers need to have the support of official documents and legislation. This research aims to verify how issues concerning Sexuality Education, gender and sexuality appear in laws, decrees and other publications that guide Brazilian Education as well as to relate them to the socio-political contexts in which they were published. To achieve our goal, we searched for these documents, covering the period from 1990 to 2018, and we focused our analysis on twenty-eight of them. The analysis showed that, in fact, the legislation not only allows, but determines that Sexuality Education be in schools. However, different political contexts have a great impact on the way in which Sexuality Education appears in the documents, sometimes explicitly, sometimes subjectively and diluted in the discourse of diversity and recently, completely silenced. In addition, recurrent cycles of advances and setbacks in different political contexts since re-democratization have culminated in gaps and discontinuities in Sexuality Education policies, impeding the development of a specific law on the subject and preventing its consolidation within Brazilian schools.

PurposeCollege-bound young people experience sexual assault, both before and after they enter college. This study examines historical risk factors (experiences and exposures that occurred prior to college) for penetrative sexual assault (PSA) victimization since entering college.MethodsA cross-sectional study, including an online population-based quantitiative survey with undergraduate students was conducted in spring 2016. Bivariate analyses and multivariable regressions examined risk and protective factors associated with ever experiencing PSA since entering college. Concurrently-collected in-depth ethnographic interviews with 151 students were reviewed for information related to factors identified in the survey.ResultsIn bivariate analyses, multiple historical factors were significantly associated with PSA in college including adverse childhood experiences and having experienced unwanted sexual contact before college (for women) and initiation of alcohol, marijuana, and sexual behaviors before age 18. Significant independent risk factors for college PSA included female gender, experiencing unwanted sexual contact before college, first oral sex before age 18, and “hooking up” (e.g., causual sex or sex outside a committed partnership) in high school. Receipt of school-based sex education promoting refusal skills before age 18 was an independent protective factor; abstinence-only instruction was not. In the ethnographic interviews, students reported variable experiences with sex education before college; many reported it was awkward and poorly delivered.ConclusionsMultiple experiences and exposures prior to college influenced the risk of penetrative sexual assault in college. Pre-college comprehensive sexuality education, including skills-based training in refusing unwanted sex, may be an effective strategy for preventing sexual assault in college. Sexual assault prevention needs to begin earlier; successful prevention before college should complement prevention efforts once students enter college.

In 2021, the majority of respondents surveyed for this study believed that sex education should be introduced in high schools. However, 19 percent of respondents stated that sex education should never be introduced in the Romanian education system.

ABSTRACT: This article is part of a pedagogical-intervention research developed in a master's course. The objective was to investigate sexuality conceptions of Youth and Adult Education (YAE) students during Science classes, as well as to propose a Didactic Sequence (DS) for Sexual Education (SE) in a school located in a settlement, in the rural area of Monte Alegre de Mina, a town in the state of Minas Gerais, Brazil. Initially, we did a literature review on the Internet searching for: "sex education in YAE in settlement schools", "sex education in YAE and the Freirean approach", and for "gender and sexuality in settlement YAE". However, there were no results for this search. Thus, this research is justified due to the lack of discussions that align the triad YAE, SE, and settlement school. Data collection used questionnaires. The results present suggestions and possibilities for discussing sexuality themes, including gender, based on students’ experiences. It is suggested the development of DS adapted to the transversality of the sexuality themes and the reality of the students in the triad context of SE, YAE, and settlement school.

ABSTRACT The space for discussing sexuality in schools is limited, even with the perspective of preventing Sexually Transmitted Infections (STIs). On demand from a high school, students linked to the Tutorial Education Program of the Psychology course and the STI/AIDS Prevention Pole Extension Project held workshops with adolescents. The objective of this project was to dialogue about sexuality and promote discussions for the prevention of STIs through 9 workshops, with the participation of 18 students. These workshops were evaluated using two questionnaires and the data were treated in three axes: Workshop Evaluation - Methodologies and Facilitators; Assessing Adolescents as Multipliers and Assessing the Theme Importance for Adolescents. It was concluded that the workshops provided a means to promote STI prevention behaviors, to encourage the responsible exercise of sexuality and enabled the formation of bonds between facilitators and adolescents.

Abstract The aim of this study was to understand family conversations about sexuality from the perspective of adolescents. We conducted an exploratory-descriptive qualitative study anchored in Paulo Freire’s dialogical framework. The data were collected using an on-line questionnaire completed by 13 adolescents aged 14-19 years living in a municipality in the south of Brazil selected using snowball sampling. A lexicographic analysis was performed of the text corpus created from the questionnaire answers. Family discussions about sexuality were dialogical and anti-dialogical. Dialogicality was related to feelings of trust and affinity, above all with mothers, while anti-dialogicality was bound to prejudice and conservatism, which was more evident in fathers. The findings show that the context of family discussions about sexuality is influenced by affective, cultural, social, and religious aspects.

According to a survey that was conducted in Japan in March 2024, the majority of respondents across all age groups mentioned that junior high school classes taught them about reproductive and sexual information, ranging from around ** to ** percent. High school and elementary school classes followed as major sources of information on these topics.

The objective of this overview was to identify and evaluate the effectiveness of sex education interventions aimed at reducing sexual risk behaviors in adolescents. A search was conducted of systematic reviews in English, Spanish and Portuguese from 1946 until July 2018 in the following databases: MEDLINE (Ovid), EMBASE, Scopus, PsyArticles, Cochrane Central Register of Controlled Trials, LILACS and additional resources. The extraction and analysis of data was synthesized in a narrative mode describing intervention, population, and key outcomes such as decreased risky sexual behavior, decreases in sexually transmitted infections, and adolescent pregnancy. There were 2289 potentially relevant studies, of which 31 systematic reviews related to adolescent interventions were included. It was demonstrated that interventions involve parents and the community as participants, are based on audiovisual media and school workshops, and their emphasis is on information and training in school. Different reviews framed in methods of psychosocial intervention based on community groups and the home as a fundamental axis were reported. Finally, a large amount of scientific evidence related to the subject was identified. New directions are presented for interventions in sexual education for adolescents based on the combination of actions and techniques, the implementation of digital technology, and socio-cultural and contextual adaptations.
