Puberty Education in a Global Context: Knowledge Gaps, Opportunities, and Implications for Policy

Exploring Menstrual Education via TikTok: A Descriptive Content Analysis

PURPOSE

TikTok has rapidly emerged as one of the foremost social media platforms for young adults and adolescents, becoming the most-downloaded app in 2022. With its broad reach across demographics, TikTok may be leveraged as a tool for teaching and destigmatizing topics such as menstruation. This study is the first to analyze the quality of menstruation-related content on TikTok.

METHODS

This cross-sectional study of TikTok videos and corresponding accounts examined six pre-determined menstruation-related hashtags in May 2023. Deductive qualitative analysis was performed between three coders to identify themes and content of the available videos.

RESULTS

A total of 140 videos created by 107 unique accounts were identified. The videos had varying purposes including audience education (66%), entertainment (35%), and product advertisement (17%). Videos mentioned various menstrual hygiene products, menstruation-related advice, and symptoms of menses. A vast majority of videos appeared to be created by laypersons with only 8% being led by health-care professionals.

DISCUSSION

With TikTok's usage as a social platform among youth, it displays potential as a tool to enhance menstrual education and destigmatization. There is a need for more menstruation experts to join the platform and provide quality material for users.

Menstrual education programs for girls and young women with intellectual and developmental disabilities: A systematic review

BACKGROUND

Providing menstrual education and guidance for menstrual management for girls and young women with intellectual disabilities is recommended to ensure smooth pubertal transitions and to support menstrual self-agency.

METHOD

The purpose of this systematic review is to explore menstrual education interventions for girls and young women with intellectual disabilities.

RESULTS

Nine studies were included. Interventions were provided in small groups (n = 4) and individually (n = 5). Most studies used dolls (n = 7) and task analysis (n = 7) to teach pad-replacement skills. All reported significant improvements in participant skills and/or knowledge following the intervention. Only one study addressed self-agency and self-esteem as an outcome of the intervention. Menstrual education for girls and young women with intellectual disabilities is largely focused on pad-replacement skills.

CONCLUSION

Further research is needed to understand the impact of menstrual health and hygiene education on variables apart from skill improvement such as self-agency and long-term health outcomes related to menstrual health.

Pubertal status and body image: An inquiry into experiences of adolescents in Ghana and Kenya

The current study uses a mixed method design to investigate Kenyan and Ghanaian adolescents' experiences of puberty, and the relations between gender, country of origin, pubertal status, and body image appraisals (N = 86; Ghana = 46, Kenya = 40, 52.9% female aged 13 and 14). Qualitative results revealed seven major themes; puberty means a universal period of growth and transition into adulthood but also evokes negative emotions of shame, anxiety, and embarrassment, being in sync with peers during puberty is important and knowing that others in their lives similarly experience puberty is reassuring. Quantitative results revealed significant gender and country differences in pubertal status and body image. Ghanaian adolescents had more advanced pubertal status and more positive body image appraisals compared to Kenyan adolescents. Moderation analysis results revealed that for the Kenyan sample, post-pubertal males had less favorable body image appraisals than their counterparts who were still pre pubertal whilst for females, post-pubertal girls had more favorable body images than their counterparts. No such effects were observed with the Ghanaian sample. The findings highlight the need for context considerations in understanding body image during the pubertal transition to help identify relevant protective factors for possible interventions. The results affirm the importance of positive body image promotions for adolescents within the African context and suggest the need for much more comprehensive sex education with gender-specific components to help allay fears about puberty, thus preventing the development of possible adaptation problems.

Pubertal development and pain incidence and characteristics in children: a 1-year prospective cohort study of a national sample

ABSTRACT

Sex differences in pain become apparent during puberty. However, the influence of key pubertal characteristics and pubertal hormones on pain is largely unknown. We examined the prospective associations between self-reported and hormone-indicated pubertal characteristics and pain incidence and severity in 10- to 11-year-old pain-free youth in the Adolescent Brain Cognitive Development (ABCD) Study over 1 year. Puberty was measured at baseline and follow-up with self-report (Pubertal Development Scale [PDS]) and hormonal assessment (salivary dehydroepiandrosterone [DHEA], testosterone, and estradiol). Pain status (yes/no), intensity, and interference (0-10 numerical rating scale) in the past month were self-reported at follow-up. Pubertal maturity, progression, and asynchrony were examined in relation to pain onset and severity through confounder-adjusted generalized estimating equations modified Poisson and linear mixed regression models. Among 6631 pain-free youth at baseline, 1-year incident pain was 30.7%. In both sexes, higher PDS scores were associated with greater risk of pain onset (relative risk [RR] = 1.10 to 1.27, P s < 0.01). In boys, higher PDS item variance was associated with greater pain incidence (RR = 1.11, 95% CI, 1.03-1.20) and interference (beta = 0.40, 95% CI, 0.03-0.76); higher PDS overall and gonadal scores were associated with higher pain intensity ( P s < 0.05). Associations with hormones were seen in boys only, with each 10-fold higher testosterone levels associated with a 40% lower risk of pain incidence (95% CI, -55% to -22%) and 1.30-point lower (95% CI, -2.12 to -0.48) pain intensity, and higher DHEA levels were associated with lower pain intensity ( P = 0.020). Relationships between pubertal development and pain in peripubertal adolescents are sex specific and puberty measurement specific and warrant further investigation.

Taking Stock: An Adaptable Research and Partnership Model for Developing Puberty Education in 10 Countries

There is a growing global interest in puberty and early adolescence and the importance of ensuring young people have the information and support they need during this critical phase of transition in the life course. This article highlights an adaptable model being used to support the development of contextually appropriate puberty education, in the form of illustrated and often bilingual books, for early adolescent girls and boys in countries around the world. This youth-centered participatory research and design model, which relies on the generation of community and government partnerships, has been employed in 10 countries thus far. Valuable learning has been documented from various contexts, including the approach's flexibility in adapting to the inputs of government and community members, incorporating local buy-in as a key ingredient for sustainability, using in-country experts for social and cultural appropriateness of illustrations and translations, and ensuring that the authentic youth voices captured through the participatory data collection and field-testing shape the educational content. The continuous integration of insights and perceptions of adults who influence young people's lives into the development process is also essential to enabling the uptake of puberty content in each new country. Parents, educators, youth service providers, and government officials are often the gatekeepers to young adolescents receiving puberty content and are thus critical to the process. This review of more than a decade of experience using this model underscores the essentiality of 2 key components-local partnership and participatory data collection-and highlights the importance of flexible approaches that are adapted to the unique sociocultural and environmental conditions in each country context.

Shared Components of Worldwide Successful Sexuality Education Interventions for Adolescents: A Systematic Review of Randomized Trials

A crucial aspect of human development is sexuality which has implications for health, particularly in adolescence, since unfavorable sexual experiences may result in physical and mental problems. Sexuality education interventions (SEI) are one of the most used actions to promote sexual health in adolescents. Nevertheless, there is variability across their components; therefore, key elements for an effective SEI targeted at adolescents (A-SEI) are not well known. Based on this background, this study aims to identify the shared components of successful A-SEI through a systematic review of randomized controlled trials (RCT). This study followed the preferred reporting items for systematic reviews and meta-analyses statement. A search was conducted in CINAHL, PsycInfo, PubMed, and Web of Science between November and December 2021. A total of 21 studies passed the inclusion test after the review of 8318 reports. A total of 18 A-SEIs were identified in these studies. The components analyzed were the intervention's approach, dose, type of intervention, theoretical framework, facilitators' training, and intervention methodology. The results established that components that should be present in the design of an effective A-SEI are behavior change theoretical models, the use of participatory methodology, be targeted at mixed-sex groups, facilitators' training, and at least ten hours of weekly intervention.

Exploring a faith-based approach to puberty education in Tanzania

Background

Many adolescents in Tanzania do not receive timely and comprehensive puberty education. This study explored faith-based organizations a site for puberty education. Two puberty books, each developed through participatory research with Tanzanian adolescents and stakeholders, were promoted to 177 Christian denomination churches in Dar es Salaam, Tanzania to understand the factors that faith leaders considered in their decision to purchase puberty books, or share information about the intervention to their peers and congregants.

Methods

Data collection included routine monitoring via weekly reports and ethnographic observation. Data were analyzed using the Ecological Framework for Health Promotion to capture how individual, interpersonal, and institutional factors influenced leaders' decisions to purchase or promote puberty books.

Results

At the individual level, leaders cited their personal experiences in their support for the intervention, but leaders' time and confidence in their ability to effectively promote books to others were barriers to participation. Interpersonally, the diffusion of information between church leaders, particularly when information came from well-known or respected leaders, emerged as an important factor in leaders' willingness to promote books. At the institutional level, leaders' decisions were impacted by resources, institutional culture, and institutional hierarchy. Importantly, twelve churches in the sample purchased books. Limited financial resources and the need to receive approval from denominational leaders were discussed by leaders as barriers to purchasing books.

Conclusions

Despite research showing high religiosity in Tanzania, the role of religious institutions in providing puberty education has remained unexplored. Our results inform future research and practice by providing an articulation of the socioecological factors that played a role in faith leaders' decisions related to puberty education interventions in Tanzania.

"Not just the consequences, but also the pleasurable sex": a review of the content of comprehensive sexuality education for early adolescents in Rwanda

BACKGROUND

Responding to adolescents' educational needs in sexual and reproductive health and rights (SRHR) is central to their sexual health and achieved through school-based comprehensive sexuality education (CSE). In 2016, Rwanda introduced CSE through the competence-based curriculum in schools to enhance learners' knowledge about sexuality, gender, and reproductive health issues, including HIV/AIDS. However, globally, the content of CSE is sometimes dissimilar, and little evidence surrounds its scope in many settings, including Rwanda. In addition, the extent to which CSE aligns with international guidelines has yet to be well known. This study assesses major areas of CSE for early adolescents in Rwanda, analyses how CSE correlates with international guidelines and makes recommendations accordingly.

METHODS

We reviewed the Rwandan competence-based curriculum to map CSE competences for early adolescents and conducted semi-structured interviews with key informants (N = 16). Eleven of the 23 curriculum documents met the selection criteria and were included in the final review. We manually extracted data using a standard form in Microsoft Excel and analysed data using frequency tables and charts. Interviews were thematically analysed in NVivo 11 for Windows.

FINDINGS

We found 58 CSE competences for early adolescents across various subjects, increasing with school grades. All recommended CSE areas were addressed but to a variable extent. Most competences fall under four recommended areas: sexual and reproductive health; human body and development; values, rights, and sexuality; and understanding gender. The least represented area is violence and staying safe. Of the 27 expected topics, there are two to six CSE competences for 13 topics, one CSE competence for each of the six others, and none for the eight remaining ones. Qualitative findings support these findings and suggest additional content on locally controversial but recommended areas of sexual pleasure, orientation, desire and modern contraceptive methods.

CONCLUSION

This study explores the CSE content for early adolescents in Rwanda and how they align with sexuality education standards. Ensuring equal coverage of CSE areas and addressing missing topics may improve CSE content for this age group and foster their SRHR.

“When I woke up I was so worried and ashamed, I thought it was a disease”: Adolescent boys’ transitions through puberty in Kenya

Growing evidence suggests a need for more focused attention on boys’ experiences of puberty in sub-Saharan Africa to assure healthy transitions into young adulthood. Existing research remains limited on the masculinity norms shaping boys’ maturation experiences in Kenya. To help fill this gap, we conducted a comparative case study using qualitative methodologies with 16–19-year-old male youth in rural and urban Kenya, and with adults interacting in boys’ daily lives. Findings suggest that Kenyan boys experience shame, confusion and silence around changes happening in their bodies; face pressures from new societal expectations as they become young men; and have adolescent lives shaped by minimal supervision, increased peer pressures and engagement in more risky health behaviors. Additional research and targeted interventions on boys transitioning through puberty and early adolescence are needed to better understand their vulnerabilities and prevent or reduce their engagement in unsafe behaviors.

“It always gets pushed aside:” Qualitative perspectives on puberty and menstruation education in U.S.A. schools

Adolescent girls in the U.S.A. often lack sufficient education on pubertal and menstrual health topics. This educational gap may be growing given the current decline in American elementary and middle schools' delivery of sexual health education. Furthermore, little is known about the actual scope and quality of existing menstruation and puberty education in U.S.A. schools. This paper provides insights into some of the challenges with the delivery of menstruation and puberty education in schools. Qualitative and participatory research methodologies were utilized with Black and Latina girls ages 15–19 and adults working with youth in three U.S.A. cities (Chicago, Los Angeles, and New York City), exploring experiences of menstruation within school and family contexts. Findings revealed tension between school responsibility and family authority in providing menstruation and puberty education in schools, school- and teacher-related delivery challenges, and inadequate and disengaging menstruation and puberty content. Further research is needed on the effectiveness and best practices for providing this education in schools, including improved understanding on student and parent preferences, delivery mediums and the scope of content.

Awareness of pubertal body changes among primary school children aged 10–14 years in Eastern Uganda; challenges and opportunities

Background

Globally, programs that educate young people about pubertal body changes are vital. In some communities, teaching sexual education in schools has been the subject of debate. This is probably why access to sexual and reproductive health information and resources is still a challenge to children aged 10–14 years.

Methods

We conducted a qualitative study design among school children aged 10–14 years. Data were collected from 19 focus group discussions (FGDs) in 16 primary schools purposively selected from Eastern Uganda. Data were transcribed, coded and thematically analysed.

Results

We established that girls in rural schools were aware of their body changes than those from urban schools. Boys in urban schools were knowledgeable of pubertal body changes than those from rural schools. We further found that girls experienced pubertal-related challenges amongst themselves and boys including lack of shavers, pain while shaving, rape, bad boy–girl relationships, unwanted early pregnancies, limited funds to buy pads, menstrual pain, etc. Boys too indicated that they experienced similar challenges and these included lack of shavers, pain during and after shaving, changes in height, raping of girls, bad boy–girl relationships, peer pressure, HIV and other STIs, limited infrastructure, voice changes, bad body odour etc. Girls and boys endeavoured to overcome pubertal-related challenges by utilising advise from teachers, parents and friends.

Conclusion

Boys and girls who were knowledgeable about puberty body changes possessed opportunities that enable them to cope with pubertal-related challenges.

Menstrual Health and Hygiene among Adolescents in the United States

STUDY OBJECTIVE

Menstrual health in adolescents has been understudied in the United States. We aimed to assess patient and provider perspectives surrounding menstrual health management and screening.

DESIGN

Our mixed-methods approach consisted of provider surveys, patient surveys, and patient interviews.

SETTING

Participants were recruited from a pediatric gynecology practice or an adolescent medicine clinic at an urban tertiary academic center.

PARTICIPANTS

Providers were pediatrics faculty or residents. Patients aged 13-24 years were eligible.

INTERVENTION

Participants completed an anonymous survey or semi-structured interview about their experiences with menstrual health.

MAIN OUTCOME MEASURES

Descriptive statistics and thematic content analysis were used for quantitative and qualitative data, respectively. Convergent parallel analysis elucidated key findings in both data sets.

RESULTS

The provider survey response rate was 65% (69/106); 15% (9/69) of providers consistently asked patients about menstrual products, whereas 44% (27/68) were concerned patients could not afford products. The patient survey response rate was 85% (101/119); 19% (19/101) of respondents reported menstrual hygiene insecurity, 55% (55/101) missed commitments during menses, and 45% (45/101) discussed menstrual products with providers. Fifteen patients were invited for qualitative interviews; 10 were conducted, and thematic saturation occurred. Interviews highlighted the importance of comprehensive early menstrual health education and providers' role in menstrual management.

CONCLUSION

Adolescence is a crucial point of entry into health care. Because taboos surrounding menstruation could limit access to health care, menstrual health education must be emphasized. Menstrual health education is provided piecemeal by parents, schools, and providers. Current practice should be reevaluated to consider comprehensive educational approaches in which health care leads.

Menstrual Equity Initiatives at USA Universities: A Multiple Case Study of Common Obstacles and Enabling Factors

Background: In recent years there has been growing momentum in the USA around addressing issues of “menstrual equity” and “period poverty,” including a proliferation of university-level initiatives seeking to provide access to free menstrual products. This multiple case study examined four such efforts at a diversity of tertiary institutions to identify the factors that facilitated or impeded success.

Methods: We conducted a qualitative multiple case study, including a desk review and key informant interviews with student and administrative actors from universities with free menstrual product initiatives. We sought to identify key learning regarding common challenges and obstacles, enabling factors which supported success and sustainability, and practical learning for future initiatives. From the desk review, four schools (n = 4) were purposively selected to represent a range of geographic regions, student population size, and university type. Purposive sampling was used to identify students and administrators engaged in the menstrual equity initiatives on each campus (n = 20; 4–6 per school). Data from the desk review and interviews were analyzed using thematic analysis.

Results: Key themes included (1) the critical role of champions, (2) the importance of social and financial support, (3) challenges diffusing menstrual equity from pilot to scale, and (4) recommendations for future initiatives. University initiatives varied greatly in terms of their scope, funding, and implementation strategy.

Conclusion: This multiple case study provides valuable insights regarding the facilitating factors and obstacles faced by initiatives providing free menstrual products at universities. To date, these initiatives have proven successful across the four case studies; however, in most cases, the scope of the initiatives was constrained by limited resources and sustainability concerns. Future campus menstrual equity strategies would benefit from cross-institutional learning and dialogue highlighting design and implementation successes and challenges.

An association between body image dissatisfaction and digit ratio among Chinese children and adolescents

Body image dissatisfaction (BID) is a negative evaluation of personal physical characteristics, including dissatisfaction with body shape, gender, sexual organs, appearance and so forth, and it plays an important role in growth and development. The second-to-fourth digit ratio (2D:4D) is recognized as a putative indicator of intra-uterine testosterone to estrogen ratio exposure, and it has been observed that higher levels of fetal testosterone exposure are associated with a lower 2D:4D. The present paper contributes to a better understanding of the biological underpinnings of BID by analyzing BID and the digit ratio (2D:4D). We found that the 2D:4D was positively related to appearance dissatisfaction in boys with first spermatorrhea, which means that low prenatal androgen exposure may increase boys’ dissatisfaction with their appearance. In girls with breast development being lower than Tanner stage II, their 2D:4D was negatively related to their body shape dissatisfaction, which means that high prenatal androgen exposure may increase girls’ dissatisfaction with their body shape. These results suggest that the prenatal androgen exposure level might play an important role in the body image dissatisfaction of the offspring.

Hearing the unheard voice-puberty experiences of young Pakistani men: A qualitative study

INTRODUCTION

Puberty experiences of male adolescents can have significant impacts on physical and psychological health outcomes. This qualitative study explored the puberty experiences of young males in Pakistan, as there are limited accounts of what shapes these puberty experiences, especially for adolescent males living in a restrictive culture.

METHODS

Twenty-two young Pakistani men (aged 18-21 years) from two urban sites in Karachi participated in individual face-to-face (n=19) and Skype (n=3) interviews. Qualitative thematic analysis was conducted using an inductive approach to identity and examine the patterns emerging from the data.

RESULTS

Participants described puberty as a challenging phase for which they were unprepared with a combination of various socio-cultural factors exposing them to negative impacts. As a result, young men expressed feelings of anxiety, embarrassment and isolation. Societal and gender norms around masculinity, sexuality and the roles and responsibilities of young men had a significant impact on how participants experienced puberty. While negative reactions towards puberty were dominant, participants described adopting coping strategies (e.g. social support) to help them deal with negative experiences.

CONCLUSIONS

Findings highlight the significance of culturally appropriate puberty education and various facilitating factors that may improve the puberty experiences for future young men. While extending current literature, this study also identifies key factors that could inform the development of health promotion programmes, which may aid adolescent males' puberty transition and positively influence their long-term health, well-being and identity.

Menstrual hygiene management in schools: midway progress update on the "MHM in Ten" 2014-2024 global agenda

Progress has been made in recent years to bring attention to the challenges faced by school-aged girls around managing menstruation in educational settings that lack adequate physical environments and social support in low- and middle-income countries. To enable more synergistic and sustained progress on addressing menstruation-related needs while in school, an effort was undertaken in 2014 to map out a vision, priorities, and a ten-year agenda for transforming girls' experiences, referred to as Menstrual Hygiene Management in Ten (MHM in Ten). The overarching vision is that girls have the information, support, and enabling school environment for managing menstruation with dignity, safety and comfort by 2024. This requires improved research evidence and translation for impactful national level policies. As 2019 marked the midway point, we assessed progress made on the five key priorities, and remaining work to be done, through global outreach to the growing network of academics, non-governmental organizations, advocates, social entrepreneurs, United Nations agencies, donors, and national governments. This paper delineates the key insights to inform and support the growing MHM commitment globally to maximize progress to reach our vision by 2024. Corresponding to the five priorities, we found that (priority 1) the evidence base for MHM in schools has strengthened considerably, (priority 2) global guidelines for MHM in schools have yet to be created, and (priority 3) numerous evidence-based advocacy platforms have emerged to support MHM efforts. We also identified (priority 4) a growing engagement, responsibility, and ownership of MHM in schools among governments globally, and that although MHM is beginning to be integrated into country-level education systems (priority 5), resources are lacking. Overall, progress is being made against identified priorities. We provide recommendations for advancing the MHM in Ten agenda. This includes continued building of the evidence, and expanding the number of countries with national level policies and the requisite funding and capacity to truly transform schools for all students and teachers who menstruate.

Internalized Body Stigma as a Barrier to Accessing Preventative Healthcare for Young Women

Internalizing stigma toward the body can have negative implications for women's sexual health. In the current study, we examined how young women's internalized stigma toward their body shape, genitals, and menstrual periods are associated with their use of preventative healthcare services for sexual health. Additionally, we tested two mechanisms that may mediate the relationship between internalized body stigma and preventative care: self-objectification (in the form of a loss of autonomy) and comfort communicating with a healthcare provider. We collected and analyzed survey data from 685 undergraduate women. We tested a serial mediation model, such that the internalization of body stigma predicted greater self-objectification, greater self-objectification predicted less comfort communicating with a provider, and discomfort communicating with a provider predicted lower receipt of preventative care. Results partially supported the proposed serial mediation model, such that internalizing stigma towards body shape, genitals, and menstrual periods was associated with discomfort communicating via greater self-objectification. Internalized stigma toward genitals and menstrual periods were significant predictors of preventative care use, even when accounting for self-objectification and communication. Findings suggest that interventions to address genital and menstrual stigma could be especially beneficial for enabling young women to seek preventative care.

The effect of teaching puberty health concepts on the basis of a health belief model for improving perceived body image of female adolescents: a quasi-experimental study

Background

As children approach adolescence, they focus increasingly on their appearance and physical attraction due to teenage body-image. Teaching the concepts of adolescent health changes an individual’s attitudes towards parts of the body. The health belief model (HBM) is one of the significant pedagogic models in health education. According to this model, the individual’s decision and motivation for adopting healthy behaviors depends on three separate categories “personal perception, adaptive behaviors, and probability of performing that action or behavior”. This study investigated the effect of teaching puberty health concepts on the basis of a HBM on perceived body image in female adolescents.

Methods

A quasi-experimental research design was used in the study. This study was conducted with 60 sixth grade girls in state elementary schools in Yazd, Iran, that were selected with cluster sampling method and assigned randomly into experimental and control groups. The experimental group were educated in the school during eight 45-min sessions based on the HBM, whereas the control group were educated using the traditional lecturing method. The data were collected with demographic and self-body image questionnaires completed before and after intervention. The data were analyzed with SPSS16 using analysis of covariance (ANCOVA).

Results

The mean age of the participants was 12.16 ± 0.74 years. The findings showed that “perceived body image” and “students’ self-attitude” improved significantly after intervention; yet, no significant difference was found between the subscales “attitudes towards weight” and “satisfaction with various parts of the body”.

Conclusion

The results of the study confirmed the efficacy and efficiency of teaching puberty health on the basis of the HBM on improving perceived body image in female adolescents.

Strengthening health care worker engagement with early adolescence in low- and middle-income countries: an overdue area for action

The very young adolescent population (ages 10-14) is currently under-served by health care systems, particularly in low- and middle-income countries. Although there is a substantial and growing effort to reach adolescents with the health services and commodities they need, such efforts often overlook the period of early adolescence given this population's lower vulnerability to risk-taking behaviors. However, early adolescence is a period of significant change, with the onset of puberty introducing physiological, emotional, and social changes in girls' and boys' lives. This period also represents a time of intensifying gendered norms, and the transition of youth from childhood focused health care (e.g. deworming programs, nutrition interventions) to additional mid- and older adolescent related care [e.g. human papilloma virus (HPV) vaccine, and contraceptive provision). Strengthening young adolescents' engagement with health care workers around preventative and promotive health behaviors could have profound impacts on their health and wellbeing, which in turn could have cascading effects across the course of their lives. Critically, young adolescents would gain trust in health care systems, and be more likely to return when significant health issues arise later in adolescence or adulthood. Such an effort requires sensitizing health care workers and building their capacity to respond to young adolescents' unique needs, by defining a package of actions that they are mandated to provide, training them, providing them with desk reference tools, and putting in place systems to provide supportive supervision and collaborative learning on the one hand, and encouraging caregivers to connect their pubescent-aged boys and girls with the health care system, on the other hand. This paper presents an argument for increased focus in particular on building attitudes and capacities of health care workers on engaging with early adolescents, applying Principle 3 of the Society of Adolescent Medicine's position paper entitled "Health Care Reform and Adolescents."

Conceptualizing Puberty as a Window of Opportunity for Impacting Health and Well-Being Across the Life Span

We promote the perspective that puberty, a separate biological process embedded in adolescence, is a "window of opportunity" for understanding and impacting health and development. First, we include a brief overview of pubertal change. Second, we propose a critical role for puberty in shaping life span health due to its connections with early life precursors, health issues and risks emerging during puberty, and health in young adulthood and beyond. Next, we discuss the importance of puberty measures in developmental research and suggest ways to make the science of puberty an important standalone research entity, as well as an essential component of studies conducted during adolescence. Finally, we discuss measurement issues, novel theoretical models of puberty, and the necessity of adopting an interdisciplinary perspective in research on puberty and in adolescence more broadly.

The New Biobehavioral Developmental Science of Puberty

This special section is the product of a small-group meeting of those who study puberty and its relevance. Our aim was to gather information and write manuscripts to inform scientists of advances and continuing obstacles, as well as to stimulate interdisciplinary research on puberty relevant across the lifespan. The themes of the nine position or review papers (and commentary), range from cell to society. We hope this introduction will entice you to read all the papers and consider how they apply or expand your next steps in research or help you synthesize the literature on puberty. We anticipate the papers can embellish your adolescent courses, and, for junior scientists, we hope the many intriguing possibilities for future research on puberty will be apparent.
