BACKGROUND Sexual health education is a critical aspect of adolescent development, equipping students with the knowledge, skills, and attitudes necessary to make informed decisions about their well-being. Despite its importance, sexual health education in the United States remains inconsistent, with only a minority of states mandating comprehensive, inclusive, and evidence-based curricula. Addressing these disparities, this study evaluates the current landscape of interdisciplinary collaboration and delivery of sexual health education programs for K-12 students. OBJECTIVE By examining existing research and program outcomes, this scoping review aim to provide actionable recommendations for educators and policymakers to foster equitable, holistic, and effective sexual health education. METHODS Studies considered for inclusion are those focused on children and adolescent sexual health programs with interdisciplinary collaboration (including medicine, social work, psychology, nursing, dental). Studies will be limited to those published in English within the United States from inception to November 2024. Five electronic databases, namely PubMed, EMBASE, ERIC, APAPsycInfo, and CINAHL will be searched for published reports. Two reviewers will independently screen titles and abstracts. The reviewers will then assess the full texts selected. In both cases, disagreements will be discussed with a third reviewer and consensus will be achieved. Data analysis will be descriptive with a narrative summary. RESULTS As this study does not have the direct involvement of human participants, an institutional ethical review will not be warranted. CONCLUSIONS As this study does not have the direct involvement of human participants, an institutional ethical review will not be warranted.

Background: TikTok has emerged as a major source of health information, including content related to intrauterine devices (IUDs). However, the accuracy, quality, and engagement patterns of IUD-related content on this platform remain insufficiently characterized. This study evaluated the informational quality, thematic focus, misinformation prevalence, and engagement metrics of widely viewed IUD-related TikTok videos. Methods: A descriptive cross-sectional content analysis was conducted of TikTok videos retrieved using 12 IUD-related search terms. Engagement metrics, creator characteristics, and content features were extracted, including educational, testimonial, and advice-seeking videos. Advice-seeking videos were included to capture user-generated concerns and inquiries that may influence engagement with health-related content on social media platforms. Informational reliability and quality were assessed using the Modified DISCERN instrument and the Global Quality Scale (GQS). Differences across groups were examined using t-tests, ANOVA, and chi-square tests. Results: A total of 458 videos were included. Nearly half were testimonial or advice-seeking (47.8%), while 38.9% were educational. Most content was produced by non-healthcare creators (76.4%). Engagement metrics did not differ significantly across video type, source, or creator qualification (all p > 0.05). Frequently discussed topics included adverse effects (36.5%), insertion experiences (31.2%), and device removal or discontinuation (19.9%). Overall informational quality was low, with mean GQS and Modified DISCERN scores of 2.0 and 1.8, respectively. Physician-created content demonstrated significantly higher quality and reliability scores (both p < 0.001). Conclusions: Widely viewed IUD-related TikTok content demonstrates high engagement but generally low informational quality.
