[The role of nursing professionals in the development and care of adolescent health in HondurasPapel dos profissionais de enfermagem no desenvolvimento e na atenção à saúde de adolescentes em Honduras]. / El papel de los profesionales de enfermería en el desarrollo y atención de la salud adolescente en Honduras.

Objective: Identify and analyze the role of nursing professionals in the development and care of adolescent health in Honduras, by analyzing the curricular content of the training provided to nursing students with respect to adolescent health, and by studying policies on adolescent health. Methods: Mixed methods study, with a sequential explanatory approach, carried out from May to July 2023 through surveys of nursing schools, analysis of policy documents, a survey with nursing professionals, and a focus group. Quantitative data were analyzed using descriptive statistics and qualitative data, applying the theoretical framework of Walt and Gilson. Results: During the research, 18 documents were analyzed and seven nursing schools, 141 nurses, and 10 key actors in leadership positions participated. The results point to the need to update and disseminate the regulatory framework, ensure the necessary resources and structure to implement sustainable intersectoral programs, and train professionals. Schools are an important space for the implementation of actions; in this context, the adoption of school nursing programs could be beneficial. Nurses were identified as key figures in program implementation and should be taken into consideration when developing policies aimed at adolescents. Conclusions: Nurses participate in various stages of the policy implementation process and can make important contributions to school health at the first level of care. To this end, it is necessary to increase the capacities of nurses and nursing educators in relation to current and relevant issues in adolescent care.

Para isso, é necessário aumentar a capacitação dos profissionais e docentes de enfermagem em tópicos atuais e relevantes da atenção a adolescentes.

Factors Associated with Family Functioning During Pregnancy by Adolescent and Young Adult Women.

Introduction: Pregnancy represents a stressful period for both women and their families. Whether the family maintains functioning during pregnancy could have significant implications on maternal and child health. In this study, we explored individual- and family-level factors associated with family functioning in adolescent and young adult mothers. Methods: This study was a secondary analysis of 295 young mothers, ages between 15 and 21 years. Multivariate logistic regression models were conducted to estimate adjusted odds ratios of exploratory factors on the risk of being in high family functioning group. The parent study was approved by the Institutional Review Boards at Yale University. Results: The mean score of family functioning was 5.14 out of 7. With the inclusion of individual-level factors (Model 1), significant associations were observed between high family functioning and having ever attended religious services (OR = 2.22, 95% CI: 1.20-4.09), low perceived discrimination (OR = 3.04, 95% CI: 1.60-5.75), and high perceived social support (OR = 3.74, 95% CI: 2.01-6.95). After including both individual- and family-level factors (Model 2), results identified significant associations between high family functioning and annual household income>$15,000 (OR = 9.82, 95% CI: 1.67-57.67, p = 0.011) and no experience of violence from any family members (OR = 4.94, 95% CI: 1.50-16.21, p = 0.008). Discussion: The models of care should be structured to support the continuity of maternity care in which health care providers have the opportunity to discover and utilize each family's strengths to provide the optimal caring experience for young mothers and their families as a unit.

Telemedicine-Based Provision of Adolescent Gender-Affirming Medical Care to Promote Equitable Access.

Purpose: To explore transgender and nonbinary (TNB) young adults' (1) interest in receiving gender-affirming medications through telemedicine before age 18 years and (2) willingness to initiate this care with primary care providers (PCPs). Methods: Data were from a survey of TNB young adults who had not received gender-affirming medications before age 18 years. Chi-square and Wald tests identified demographic differences in telemedicine interest and willingness to initiate medications with their PCP as minors. Results: Among 280 respondents, 82.5% indicated interest in telemedicine and 42.0% were willing to initiate medications with their PCP. Black/African American respondents were more likely to indicate interest in telemedicine than White and multiracial respondents. Respondents from rural areas were more likely to indicate willingness to initiate medications with their PCP than those from urban areas. Conclusions: Telemedicine expansion and further support for PCPs may represent critical opportunities to promote equitable access to adolescent gender-affirming care.

A cross-sectional study of variations in schoolwork stress in academic upper secondary school classes in Mid-Norway.

AIMS: This paper investigates stress related to schoolwork among students in academic upper secondary schools. The research questions asked are: 1. To what degree does students' schoolwork stress vary between academic classes?; And 2. are perceptions of classroom goal orientation, academic achievement, sex and parental education related to schoolwork stress? METHODS: A cross-sectional survey was done in the final year of upper secondary school in 71 school classes from 13 schools. A total of 1955 students in academic education programs were invited to participate in the survey, and 1511 completed the survey; the response rate was 77%. The outcome measure was a composite measure of schoolwork stress (alpha = 0.81). Multilevel modeling was used to estimate school class-level effects. RESULTS: The mean value of schoolwork stress was 4.0, on a scale of 1 (very little schoolwork stress) to 6 (very high schoolwork stress). About half of the students reported a score of 4 or higher. The analysis showed that individual characteristics explained most of the variation in schoolwork stress. Girls experienced a much higher level of schoolwork stress than boys (mean values of 4.3 and 3.6, respectively). There was also a significant class-level effect, estimated to 6% of the variance. Students' perceptions of classroom goal orientation was also associated with schoolwork stress. CONCLUSIONS: The main contribution was the discovery of significant variations in schoolwork stress between school classes. We also found that higher mastery climate was linked to lower schoolwork stress, whereas higher performance climate was linked to higher schoolwork stress.

Acute Safeguarding Essentials in Modern-day Paediatrics: Sexual Relationships, Consent and Confidentiality.

As the third case in the acute safeguarding essentials in modern-day paediatrics series, this article focuses on sexual relationships, consent and confidentiality. Using the scenario of a 15-year-old girl presenting to the emergency department with a positive pregnancy test, it begins with a guide to taking a psychosocial history in young people followed by discussion about some of the legality surrounding sexual relationships in adolescents, issues around consent and considerations for confidentiality in this age group.

Children born to subfertile couples, how are they doing? Evidence from research.

More than 10 million children have been born with assisted reproductive technology (ART) as we begin to enter the third generation of individuals conceived by ART. Here we summarise key messages from an enlarging body of literature regarding their health. Earlier research had pointed towards increases in perinatal, neonatal and neurological risks, such as preterm birth, low birth weight, congenital malformations and cerebral palsy. Many of these risks have continued to persist in most recent work but have shown reduction. Newer research proposes long-term cardiometabolic and endocrine concerns. Fortunately, most reports conclude there is little or no risk of increased childhood malignancy or abnormal neurodevelopment. Moving forward, new research may benefit from changes in comparator groups and a better understanding of infertility per se in ART, and the confounding role it probably plays in many of the known risk associations, to reliably scan the horizon for health threats for individuals born after ART.

Move and Thrive: Development of an Adolescent Friendly and Inclusive Online Fitness Resource.

While physical activity (PA) is a strong protective factor for adolescents, many youth experience discrimination and intimidation in traditional fitness spaces. This is especially true for youth of color, youth in larger bodies, and transgender youth. This manuscript describes the development of Move and Thrive, an online resource for PA promotion designed specifically for adolescents prioritizing inclusivity and diversity. Working with Community and Youth Advisory Boards, we developed guiding principles of Move and Thrive: to create resources that are 1) youth and community driven; 2) inclusive of diverse representation; 3) body and weight neutral; 4) trauma informed; and 5) accessible. We developed a guide for PA instructors to use trauma informed approaches; avoid mention of weight talk or physical appearance; use gender inclusive language; and offer multiple options to improve accessibility. Specific care was taken to hire instructors diverse in body size, race, ethnicity, and gender identity. The first iteration of Move and Thrive was launched in March 2021, and the current resource contains 72 PA videos. Over the course of 12 months, the site had more than the site had over 9,000 views in over 40 countries, including six continents. Users have reported high levels of satisfaction with Move and Thrive, and physicians have responded enthusiastically to sharing Move and Thrive as a free resource for adolescents. University of Minnesota Move and Thrive Project is currently available on an ad-free YouTube Channel. We believe that Move and Thrive has the potential to reach populations historically excluded from PA resources.

Changing trends in the global, regional, and national burden of iodine deficiency among adolescents and young adults: population-based study.

Iodine is a micronutrient required for the production of thyroid hormones, which regulate metabolism, growth, and neurodevelopment. Iodine deficiency among adolescents and young adults is a major global health issue. We analyzed data from the Global Burden of Disease 2019 database to calculate the prevalence, incidence, and disability-adjusted life-year (DALY) rates of iodine deficiency among adolescents and young adults. We explored the specific year with the most substantial changes in the trends of iodine deficiency among adolescents with annual percentage change (APC) by Joinpoint Regression analysis. Descriptive analyses were conducted to characterize the iodine deficiency burden according to age, sex, location, and sociodemographic index (SDI) quintiles. All measures are listed with 95% uncertainty intervals (UIs), and all rates are reported per 100,000 individuals. From 1990 to 2019, the iodine deficiency prevalence rate among adolescents decreased from 3082.43 (95% uncertainty interval [UI], 2473.01-3855.86) to 2190.84 (95% [UI], 1729.18-2776.16) per 100,000 population, with an AAPC of -1.15 (95% confidence interval [CI], -1.29 to -1.02). Regarding the SDI in 2019, the highest prevalence and DALY rates of iodine deficiency were reported in low-SDI countries. In 1990, Southeast Asia had the highest prevalence and DALYs rates for iodine deficiency among adolescents, while in 2019, Africa had the highest prevalence rate (3330.12). CONCLUSION: Globally, the iodine deficiency burden among adolescents has substantially decreased since 1990; however, low-SDI countries still bear a great burden. Implementation measures and monitoring systems should be strengthened to reduce the iodine deficiency burden, especially among adolescents. WHAT IS KNOWN: • Iodine deficiency can cause severe or irreversible developmental disorders, particularly in adolescents and young adults. • Universal Salt Iodization was implemented for ensuring appropriate iodine intake. WHAT IS NEW: • We found substantial declines in the prevalence rates of iodine deficiency among adolescents during the past three decades. Globally, the disability-adjusted life-year rate of iodine deficiency among adolescents decreased from 56.17 in 1990 to 35.38 in 2019. • Iodine deficiency among adolescents in low- sociodemographic index countries still bear a great burden.

Understanding Factors Affecting Health Providers' Perceptions of Pharmacist Roles in HPV Vaccine Administration.

Human papillomavirus (HPV) is a viral infection that sexually active females and males may be exposed to in their lifetime. The HPV vaccine is highly recommended especially among children to protect them before their anticipated exposure to HPV, however, vaccination uptake in Hawai'i remains low. As of 2017, legislation allows pharmacists to vaccinate for adolescent vaccines with the potential to increase access and opportunities for patients to complete the HPV vaccine series. Physicians in Hawai'i were surveyed to examine physicians' awareness of this law, their perceptions of the role of pharmacists, and willingness to send adolescent patients to pharmacies; 137 responses were received and analyzed. Overall, 72% (n=99) of respondents were willing while 28% (n=38) were unwilling to send patients to pharmacies for vaccines. Physicians view pharmacists' role as helpful but have concerns regarding correct administration and tracking doses given. Results show potential for more physician-pharmacist collaborations through further education and trainings for pharmacists and health providers to increase physician referrals for adolescent vaccine services in pharmacies.

Assessing Biomedical and Psychosocial Factors in a Cross-Sectional Study of School Dropouts Among Pregnant Adolescents and Young Mothers in Quito, Ecuador.

BACKGROUND: Over nearly three decades, Ecuador experienced a significant rise in adolescent motherhood. OBJECTIVES: By focusing on social, health, and psychological aspects, the research aims to reveal the complex factors influencing the decision to discontinue education. The emphasis on providing a platform for direct expression of personal experiences not only adds qualitative depth to the study but also ensures that the voices of those involved are heard authentically. METHODS: Employing a nonexperimental, descriptive, cross-sectional approach with qualitative and quantitative methods, the research delves into the interplay of biological, psychological, and social factors. Descriptive statistics, presented through tables and graphs, were used for variable analysis, complemented by inferential statistics to validate hypotheses. Focus group sessions, processed with ATLAS.ti (ATLAS.ti Scientific Software Development GmbH, Berlin, Germany) underwent a thorough review in workshops with Servicio de Atención Integral para Adolescentes (SAIA) experts. Adolescent participants were randomly recruited through the hospital's system. RESULTS: The findings unveiled a significant dropout rate among adolescents, where pregnancy was just one factor influencing their decision. Those discontinuing education often embraced a life project centered on motherhood and domestic roles, facing domestic violence and mental health disorders. In contrast, those persisting with education were driven by professional development, facing challenges but benefiting from family support. Despite unwanted pregnancies and low contraceptive use, many found personal growth and identity affirmation in motherhood. CONCLUSIONS: Our research highlights key insights into factors like pregnancy desire, contraception, reactions, and challenges. Urgent action is needed to address systemic problems and provide holistic support, acknowledging the resilience and validity of choices made by adolescent mothers in balancing motherhood with education and career goals.

Gender diversity among adolescents with obesity in a weight management programme.

Gender dysphoria (GD) and obesity share commonalities, including associations with mental health comorbidities, disordered eating, body dissatisfaction and may intensify with physical and developmental changes during adolescence. While associations of obesity and gender diversity have been identified, rates of gender diversity among adolescents with obesity remain unclear. The aim was to examine gender diversity among adolescents with obesity in a weight management programme. A single-centre cross-sectional questionnaire study was conducted. Eligible adolescents received the Gender Identity/GD Questionnaire for Adolescents and Adults (GIDYQ-AA), a validated instrument measuring gender diversity and GD. Gender identities, sexual orientations, questionnaire scores, and frequency of GD (GIDYQ-AA score <3) were determined. The relationship of GIDYQ-AA scores and BMI Z-score (BMIz) was assessed. Of 72 consenting youth, 29 assigned females (AF) and 17 assigned males (AM) completed GIDYQ-AA and demographic questions. Seventeen (59%) AF reported non-heterosexual orientations, and 6 (21%) reported non-cisgender identities. One (6%) AM reported non-cisgender identity. Two (4%) AF individuals had GD based on GIDYQ-AA scores. GIDYQ-AA scores did not correlate with BMIz. In conclusion, adolescents with obesity, particularly AF with non-heterosexual orientation, reported high rates of non-cisgender identity and GD. Routine screening for gender-related concerns in weight management settings may be warranted.

Food Insecurity and Ideal Cardiovascular Health Risk Factors Among US Adolescents.

BACKGROUND: Food insecurity, a social and economic condition of limited availability of healthy food, is a risk factor for adverse cardiovascular health outcomes among adults; few studies have been conducted in adolescents. This study explores the association between food insecurity and cardiovascular health risk factors among a nationally representative sample of US adolescents, adopting the American Heart Association's Life's Essential 8 metric. METHODS AND RESULTS: We analyzed data from 2534 adolescents aged 12 to 19 years from the 2013 to 2018 National Health and Nutrition Examination Surveys. In the sample, 24.8% of adolescents lived in food-insecure households. After multivariable adjustment, food insecurity was associated with a 3.23-unit lower total Life's Essential 8 score (95% CI, -6.32, -0.15) and lower scores on diet quality (ß=-5.39 [95% CI, -8.91, -1.87]) and nicotine exposure (ß=-4.85 [95% CI, -9.24, -0.45]). Regarding diet, food insecurity was associated with 5% lower Healthy Eating Index-2015 scores [95% CI, -7%, -2%], particularly lower intakes of whole grains and seafood/plant proteins and marginally higher intake of added sugar. Regarding nicotine exposure, food insecurity was associated with ever use of a tobacco product among m (odds ratio, 1.74 [95% CI, 1.20-2.53]). Compared with their food-secure counterparts, food-insecure male (odds ratio, 1.98 [95% CI, 1.07-3.65]) and female (odds ratio, 3.22 [95% CI, 1.60-6.45]) adolescents had higher odds of living with a current indoor smoker. CONCLUSIONS: In this nationally representative sample of adolescents, food insecurity was associated with multiple indicators of cardiovascular health risk. These findings underscore the need for public health interventions and policies to reduce food insecurity and improve cardioprotective behaviors during adolescence, with particular efforts targeting diet quality and nicotine exposure.

Lessons learned from conducting a community-based, nurse-led HIV prevention trial with youth experiencing homelessness: Pivots and pitfalls.

OBJECTIVE: This article highlights key lessons learned while conducting a nurse-led community-based HIV prevention trial with youth experiencing homelessness (YEH), focusing on sexually transmitted infections testing and treatment, intervention sessions, community partnerships, and participant recruitment and retention. DESIGN: The insights and experiences shared aim to inform future research and the design of interventions targeting populations at high risk, particularly when facing unanticipated challenges. By addressing these areas, the article contributes to the decision-making for the design and delivery of effective strategies to improve the health outcomes among marginalized populations. RESULTS: The findings underscore the importance of flexibility and active participant engagement, cultivating strong relationships with community partners, utilizing technology and social media, and fostering a diverse research team that represents the heterogeneity of youth experiencing homelessness across race/ethnicity, gender identity, sexual orientation, and lived experiences. CONCLUSIONS: These recommendations aim to enhance participant access, engagement, and retention, while promoting rigorous research and meaningful study outcomes for YEH.

The Effect of Using a Client-Accessible Health Record on Perceived Quality of Care: Interview Study Among Parents and Adolescents.

BACKGROUND: Patient-accessible electronic health records (PAEHRs) are assumed to enhance the quality of care, expressed in terms of safety, effectiveness, timeliness, person centeredness, efficiency, and equity. However, research on the impact of PAEHRs on the perceived quality of care among parents, children, and adolescents is largely lacking. In the Netherlands, a PAEHR (Iuvenelis) was developed for preventive child health care and youth care. Parents and adolescents had access to its full content, could manage appointments, ask questions, and comment on written reports. OBJECTIVE: This study aims to assess whether and how using this PAEHR contributes to perceived quality of care from a client's perspective. METHODS: We chose a qualitative design with a phenomenological approach to explore how parents and adolescents perceived the impact of using a PAEHR on quality of care. In-depth interviews that simultaneously included 1 to 3 people were conducted in 2021. In total, 20 participants were included in the study, representing parents and adolescents, both sexes, different educational levels, different native countries, and all participating municipalities. Within this group, 7 of 13 (54%) parents had not previously been informed about the existence of a client portal. Their expectations of using the client portal, in relation to quality of care, were discussed after a demonstration of the portal. RESULTS: Parents and adolescents perceived that using Iuvenelis contributed to the quality of care because they felt better informed and more involved in the care process than before the introduction of Iuvenelis. Moreover, they experienced more control over their health data, faster and simpler access to their health information, and found it easier to manage appointments or ask questions at their convenience. Parents from a migratory background, among whom 6 of 7 (86%) had not previously been informed about the portal, expected that portal access would enhance their understanding of and control over their care processes. The parents expressed concerns about equity because parents from a migratory background might have less access to the service. Nevertheless, portal usability was regarded as high. Furthermore, both parents and adolescents saw room for improvement in the broader interdisciplinary use of Iuvenelis and the quality of reporting. CONCLUSIONS: Using Iuvenelis can contribute to the client-experienced quality of care, more specifically to perceived person centeredness, timeliness, safety, efficiency, and integration of care. However, some quality aspects, such as equity, still need addressing. In general, client information about the portal needs to be improved, specifically focusing on people in vulnerable circumstances, such as those from migratory backgrounds. In addition, to maximize the potential benefit of using Iuvenelis, stimulating a person-centered attitude among professionals is important. Considering the small number of adolescent participants (n=7), adding quantitative data from a structured survey could strengthen the available evidence.

Influence of vitamin D supplementation on growth, body composition, pubertal development and spirometry in South African schoolchildren: a randomised controlled trial (ViDiKids).

OBJECTIVE: To determine whether weekly oral vitamin D supplementation influences growth, body composition, pubertal development or spirometric outcomes in South African schoolchildren. DESIGN: Phase 3 double-blind randomised placebo-controlled trial. SETTING: Socioeconomically disadvantaged peri-urban district of Cape Town, South Africa. PARTICIPANTS: 1682 children of black African ancestry attending government primary schools and aged 6-11 years at baseline. INTERVENTIONS: Oral vitamin D3 (10 000 IU/week) versus placebo for 3 years. MAIN OUTCOME MEASURES: Height-for-age and body mass index-for-age, measured in all participants; Tanner scores for pubertal development, spirometric lung volumes and body composition, measured in a subset of 450 children who additionally took part in a nested substudy. RESULTS: Mean serum 25-hydroxyvitamin D3 concentration at 3-year follow-up was higher among children randomised to receive vitamin D versus placebo (104.3 vs 64.7 nmol/L, respectively; mean difference (MD) 39.7 nmol/L, 95% CI 37.6 to 41.9 nmol/L). No statistically significant differences in height-for-age z-score (adjusted MD (aMD) -0.08, 95% CI -0.19 to 0.03) or body mass index-for-age z-score (aMD -0.04, 95% CI -0.16 to 0.07) were seen between vitamin D versus placebo groups at follow-up. Among substudy participants, allocation to vitamin D versus placebo did not influence pubertal development scores, % predicted forced expiratory volume in 1 s (FEV1), % predicted forced vital capacity (FVC), % predicted FEV1/FVC, fat mass or fat-free mass. CONCLUSIONS: Weekly oral administration of 10 000 IU vitamin D3 boosted vitamin D status but did not influence growth, body composition, pubertal development or spirometric outcomes in South African schoolchildren. TRIAL REGISTRATION NUMBERS: ClinicalTrials.gov NCT02880982, South African National Clinical Trials Register DOH-27-0916-5527.

Family and developmental correlates of adolescent involvement in decision making about screen use.

Objective: Assess how child involvement in making rules about screen time relates to age, child prosocial functioning, and amount of screen use. Methods: NORC's AmeriSpeak Panel was used to recruit a nationally representative sample of parents or guardians of school-aged children (age 5-17) in the United States (n = 2084). Parents completed survey that included measures of screen time, child involvement in rule making about screen use, family functioning, and dimensions of child psychosocial functioning. Results: Across all age categories, most families had some form of rules about the allowable amount of screen-based digital media for uses other than schoolwork: 86% of elementary school-aged children (ages 5 to 10), 81% of middle school-aged children (ages 11-13), and 61% of high school aged children (ages 14-17). Across all age groups, having rules was associated with fewer hours of screen time (elementary school: B = -1.31, 95% CI = -1.80 to -0.81, p < 0.001; middle school: B = -1.40, 95% CI = -2.20 to -0.59, p < 0.001; high school: B = -0.97, 95% CI = -1.68 to -0.27, p = 0.007). Child involvement in making rules was significantly greater for high school students as compared to elementary school students (ß=0.12, p < 0.001), and not associated with high school- or middle-school aged child screen time. Across all age groups, child involvement in making rules was associated with higher levels of prosocial functioning (elementary school: ß=0.07, p < 0.001; middle school: ß=0.19, p = 0.001; high school: ß=0.21, p < 0.001). Conclusions: Child involvement in making rules about screen use may be an opportunity to strengthen developmentally important competencies, as part of a broader autonomy-supportive approach to parenting.

Per- and polyfluoroalkyl substances and bone mineral content in early adolescence: Modification by diet and physical activity.

BACKGROUND: Per- and polyfluoroalkyl substance (PFAS) exposures may negatively impact bone mineral accrual, but little is known about potential mitigators of this relation. We assessed whether associations of PFAS and their mixture with bone mineral content (BMC) in adolescence were modified by diet and physical activity. METHODS: We included 197 adolescents enrolled in a prospective pregnancy and birth cohort in Cincinnati, Ohio (2003-2006). At age 12 years, we collected serum for PFAS measurements and used dual-energy x-ray absorptiometry to measure BMC. We calculated dietary calcium intake and Health Eating Index (HEI) scores from repeated 24-h dietary recalls, physical activity scores using the Physical Activity Questionnaire for Older Children (PAQ-C), and average moderate to vigorous physical activity (MVPA) based on accelerometry. We estimated covariate-adjusted differences in BMC z-scores per interquartile range (IQR) increase of individual PFAS concentrations using linear regression and per simultaneous IQR increase in all four PFAS using g-computation. We evaluated effect measure modification (EMM) using interaction terms between each modifier and PFAS. RESULTS: Higher serum perfluorooctanoic acid, perfluorooctanesulfonic acid, and perfluorononanoic acid concentrations and the PFAS mixture were associated with lower BMC z-scores. An IQR increase in all PFAS was associated with a 0.27 (-0.54, 0.01) lower distal radius BMC z-score. Associations with lower BMC were generally stronger among adolescents classified as < median for calcium intake, HEI scores, or MVPA compared to those ≥ median. The difference in distal radius BMC z-score per IQR increase in all PFAS was -0.38 (-0.72, -0.04) for those with

Understanding Adolescents' Experiences With Menstrual Pain to Inform the User-Centered Design of a Mindfulness-Based App: Mixed Methods Investigation Study.

BACKGROUND: Digital interventions are increasingly popular for the provision of nonpharmacological pain interventions, but few exist for adolescents with menstrual pain. User-centered design involves incorporating users across phases of digital health intervention design, development, and implementation and leads to improved user engagement and outcomes. A needs assessment is the first step of this approach. OBJECTIVE: The goal of this study was to conduct a needs assessment to understand menstrual pain management needs and preferences and mindfulness experiences, preferences, and knowledge of adolescents with menstrual pain to inform the future development of an app for managing menstrual pain. METHODS: We used an explanatory sequential mixed method design that included a survey followed by focus groups. Adolescents aged 13-17 years completed a survey (n=111) and participated in focus groups (n=16). Data were analyzed using descriptive statistics and thematic content analysis and synthesized to provide specific recommendations based on adolescent responses. RESULTS: Adolescents (n=111) who completed the survey reported a moderate understanding of mindfulness and menstrual pain. Over three-quarters (n=87, 78%) of participants practiced some form of mindfulness and 87% (n=97) of survey participants used nonpharmacological pain management strategies. Teens had a moderate perception that mindfulness could help their menstrual pain (mean 4.51/10, SD 2.45, with higher scores suggesting more interest). Themes were generated related to mindfulness experiences, menstrual pain knowledge and experiences, and app functionality. These themes underscored adolescents' need for continued support and flexible access to mindfulness activities; their awareness of multiple influences to pain, with potential for further education in this area; and the need for menstrual pain-specific content, along with content relevant to typical day-to-day experiences of adolescents. CONCLUSIONS: Adolescents with menstrual pain have an interest in using a mindfulness app for pain but have unique needs that need to be addressed to ensure app engagement and relevance for this population. Concrete recommendations for future app development are provided.
