Adolescent Health

Background: Most adult women with irregular periods of unknown cause report symptoms dating back to early adolescence. This study aims to learn how girls' periods change in the 2 years after their first period. We are also looking at girls who may have a condition called PCOS. This will help researchers learn what healthy puberty looks like and how they can spot signs of hormone problems early on. Objective: To learn how long it takes girls to develop regular menstrual cycles after their first period. Eligibility: Healthy girls ages 8-14 who either (1) haven't had their first period but show signs of puberty, such as breast development and hair in the genital area; or (2) had their first period in the past 6 months Girls at risk for PCOS age 8-14 who have a mom or sister with PCOS Girls with irregular menstrual cycles age 11-17.5 To compare with the girls, we are looking at women \>=18-34 years old with PCOS, Healthy women \>= 18-34 years old without PCOS, and Mothers of pediatric participants age 18-65 Design: Both parents or guardians must allow their daughter to participate. They must attend all study visits with her. Participants will first be screened by phone. Those who qualify will be screened in person. They will have a physical exam. They will give blood and urine samples. They will have an ultrasound of their abdomen. They will fill out questionnaires. They will sit in a BOD POD for 6 minutes: This is an egg- shaped machine that takes body measurements. They have the option to provide DNA samples. Participants will have sets of visits at home or at the clinic about every 6 months. The number of visits in each set will depend on their menstrual cycle. Then they will have a final visit. Visits will include repeats of the screening tests. There are additional parts that participants may choose to be involved in depending on how involved they want to be. At home, participants will collect their urine daily to measure hormones. They will keep a diary of their periods. Adults: Women with known PCOS will complete the same Screening Visit as the girls and will collect dried urine specimens at home for 8 weeks; The Healthy control women group will complete the same Screening Visit as the girls and collect dried urine specimens at home for 2 menstrual cycles; The Mothers of pediatric participants group will complete a Screening Visit (informed consent, urine pregnancy test) and collect vaginal swab specimens at home for 2 menstrual cycles (approx. 8 weeks)....

This initiative aims to improve flourishing and quality of life of secondary school students, reduce mental distress (e.g., depression and suicidal ideation), enhance their understanding of mental health (e.g., mental health literacy) and help-seeking intention, and foster a supportive school environment (e.g., school climate-caring relationship, and sense of community). Also, this initiative aims to improve students' process of change in psychological (e.g., mattering, emotion regulation, empowerment) and social (e.g., trust belief) aspects and mental health awareness (e.g., mental health stigma). The feasibility, acceptability, and sustainability of the programme from multiple perspectives (e.g., students, student leaders, and stakeholders) will also be evaluated. In addition, the cost-effectiveness of delivering this programme (e.g., the incremental cost-effectiveness ratio (ICER)) among secondary schools in Hong Kong will be assessed. The programme will be implemented among students in 130 local secondary schools over three academic years. The first is a pilot phase (Year 1), which 40 schools will implement the intervention and student participants will be evaluated at pre- (T0) and post-intervention (T1) using questionnaires. In this stage, participatory research will be conducted before and after the intervention among students, student leaders, and stakeholders in 20 pilot schools to co-design the intervention, ensuring the programme meet the actual wellness needs of youth. In following two academic years, an additional 90 schools will participate in a cluster randomized controlled trial (RCT) with a 1:1 ratio between intervention and waitlist control groups. Each year, 45 schools will implement the intervention. Summative evaluation will be conducted among RCT schools at T0 and T1, and 3-month follow-up (T2). Quantitative data be collected to assess the effectiveness of intervention, and qualitative data will provide understanding of students' and stakeholders' perspectives of the intervention implementation. Cost outcomes will include intervention costs and cost savings, calculated from the payer (i.e., JC/government) perspective using administrative records or validated tools. The primary outcome of cost-effectiveness will be the quality-adjusted life-years (QALYs) of students. Cost of implementing the intervention program and QALYs will be used to evaluate the cost-effectiveness of the intervention, for example, estimate the incremental cost-effectiveness ratio (ICER).

The purpose of this study is to evaluate the effectiveness of the MEST work strategy in upper secondary schools. MEST is a school based, health promoting intervention delivered by school health services and designed to strengthen students' health literacy and mental well being. The study assesses whether implementation of the MEST work strategy results in improved health literacy and mental well being compared with usual school health services. This study is a cluster randomized superiority trial in which upper secondary schools are assigned either to an intervention group implementing the MEST work strategy or to a control group continuing with school health services as usual. Student reported outcomes are collected using digitally administered questionnaires during school hours at baseline, prior to initiation of the intervention, and at 4 and 9 months following intervention initiation (end of the school year).

Menstruation after menarche is a multidimensional experience affecting adolescents' quality of life, school attendance, and psychological adjustment. Educational and awareness-based interventions improve menstrual knowledge, attitudes, and coping behaviors; however, randomized controlled trials evaluating hybrid body awareness-based interventions are limited. This study aims to evaluate the effect of a hybrid body awareness-based intervention on menstrual symptoms, menstrual attitudes, and self-regulation levels in post-menarche adolescent girls.

This community-based cross-sectional study aims to assess the fulfilment of adolescent rights in health, education, protection, and community participation among adolescents aged 15-19 years living in Beni Adi village, a rural community in Assiut Governorate, Egypt.

The investigators are writing to inform participants about a study being carried out by a research group from the University of Granada and the University of Seville, in which the participant's son/daughter is invited to participate. The study has been approved by the Provincial Research Ethics Committee of Granada under code 202499906944441. The sole intention of the investigators is to ensure that participants receive correct and sufficient information to assess and decide whether or not to give consent for the child's participation in this study. The information sheet should be read carefully, and any questions may be addressed to the investigators. The objective of the study is to culturally adapt the program It's Your Game: Keep it Real (IYG), which aims to prevent risky sexual and affective behaviors in adolescents. The IYG program consists of 12 lessons, each lasting 45 minutes. These lessons aim to help the child identify personal norms and boundaries regarding sexuality, recognize situations that might challenge these boundaries, and develop refusal skills to maintain them. The program also covers topics such as the characteristics of healthy and unhealthy relationships, friendships, anatomy and reproduction, the social, emotional, and physical consequences of sexual activity, the consequences of teenage pregnancy and STIs, condom and contraceptive use, and communication skills. This adaptation will involve the child completing all 12 lessons (two lessons per week over a period of six weeks) that make up the IYG program, as well as filling out a series of questionnaires. These questionnaires will allow the investigators to assess the usability of the program in Spain (including ease of use, comprehension, acceptability, as well as aspects most liked and suggestions for improvement). Participation is entirely VOLUNTARY AND ANONYMOUS, and consent may be withdrawn at any time, without providing any explanation and without this affecting the care the child will receive in any way. In all cases, the CONFIDENTIALITY of the data collected will be maintained in accordance with the European Union General Data Protection Regulation (GDPR) 2016/679 and the Spanish Organic Law on the Protection of Personal Data and Guarantee of Digital Rights (LOPD-GDD) 3/2018, of December 5. Regarding the study results, these may be shared with the scientific community through presentations, conferences, and/or publications. The investigators express appreciation in advance for cooperation in this study.

To adapt the Screening and Support for Youth (SASY) intervention and approach to recruitment for racial, ethnic and linguistic diverse youth aged 12-17 in the Denver Health catchment area

The goal of this study is to learn whether a digital tool can help improve HIV knowledge, self-awareness, and testing among adolescents in Yogyakarta, Indonesia. The tool includes online HIV education, a self-assessment for HIV risk, and access to trained peer educators for support. The study will also explore how comfortable and willing adolescents are to use this kind of digital health service. The main questions the study aims to answer are: * Can this digital tool help adolescents better understand HIV and their personal risk? * Will more adolescents be willing to get tested for HIV after using the tool? * What factors affect whether adolescents accept and use digital HIV services? Researchers will compare two groups of high school students: * One group will use the digital tool for 6 weeks * The other group will receive standard HIV education (not through the tool) Participants will: * Answer surveys before and after the 6-week period * Learn about HIV through videos and interactive content * Use the tool to assess their personal HIV risk * Receive support from trained peer educators (online) The researchers hope this study will lead to new ways of using technology to improve HIV prevention and testing for young people.

The overarching goal of this work is to address the limited access to evidence-based health behavior and lifestyle interventions for youth and families most impacted by preventable chronic diseases, including obesity and type 2 diabetes. In the current project, we implement a small single-arm pilot and feasibility trial of Health Without Barriers/Salud Sin Barreras (HWB/SSB), a culturally-adapted, whole-family intensive health behavior and lifestyle intervention to 11-19-year-old adolescents and their families living in Northern Colorado. Objectives are refining the HWB/SSB community facilitator training, evaluating the feasibility and acceptability of HWB/SSB implementation, and characterizing changes in health outcomes among adolescent participants.

The goal of this implementation research study is to understand whether a package of community-based interventions can increase access to and uptake of the human papillomavirus (HPV) vaccine among very young adolescent girls and boys in the North and Far North Regions of Cameroon. The main questions this study aims to answer are: * Can a package of community-based interventions increase delivery of routine HPV vaccination to boys and girls aged 9-13 in Cameroon's North and Far North Regions? * What is the acceptability, feasibility, cost, and potential for maintenance and scale of an integrated health intervention to deliver routine HPV vaccination in Cameroon? To evaluate the effectiveness of the intervention, researchers will compare HPV vaccination within regions where the new intervention model is being implemented (intervention areas) to regions where the new routine HPV vaccination delivery model is not being implemented (comparison areas) for approximately 1 year before the new intervention model is implemented and for approximately 9 months after the start of implementation to compare changes over time and between intervention and comparison areas. The study will evaluate the effect of the intervention on HPV vaccination delivery using routine health facility data. To understand acceptability, feasibility, implementation, and potential for scale, the study will enroll participants including health officials and providers, adolescents girls receiving HPV vaccination and other services in intervention areas, and their parents/caregivers. The study will be conducted in two phases, with the first phase focused on gathering formative data through interviews with key informants. This data will be used to inform the design of the intervention, which will be implemented and evaluated in phase 2. Only phase 1 of this study protocol has been currently approved. In phase 1, key informant interview participants will be asked to participate in a an interview to discuss HPV vaccination services and their perspectives on how to integrate HPV vaccination within existing community-based and health facility structures and programs. Key informants will include government officials, health program implementers, representatives from non-government organizations working on HPV vaccine delivery, and healthcare providers, as well as community leaders including school and religious leaders.

The goal of this implementation research study is to understand whether a package of community-based interventions can increase access to and uptake of the human papillomavirus (HPV) vaccine among very young adolescent girls in rural Ethiopia. The main questions this study aims to answer are: * Can a package of community-based interventions increase delivery of routine HPV vaccination to girls aged 9-14 in rural Ethiopia? * Is an intervention model that incorporates strategies that address gender norms and gender-specific barriers more effective at increasing delivery of routine HPV vaccination than a model that does not explicitly address gender? * What is the acceptability, feasibility, cost, and potential for maintenance and scale of an integrated health intervention to delivery routine HPV vaccination in rural Ethiopia? To evaluate the effectiveness of the intervention, researchers will compare HPV vaccination within regions where the new intervention model is being implemented (intervention areas) to regions where the new routine HPV vaccination delivery model is not being implemented (comparison areas) for approximately 1 year before the new intervention model is implemented and for approximately 1 year after the start of implementation to compare changes over time and between intervention and comparison areas. The study will evaluate the effect of the intervention on HPV vaccination delivery using routine health facility data. To understand acceptability, feasibility, implementation, and potential for scale, the study will enroll participants including health officials and providers, adolescents girls receiving HPV vaccination and other services in intervention areas, and their parents/caregivers. These participants may be asked to participate in one or more of the following: * Completing a short questionnaire after receiving health services, including HPV vaccination, and their knowledge and attitudes towards HPV vaccination and experiences of care * Participating in an interview or a focus group discussion to discuss HPV vaccination services and the role of the intervention in delivering care
