There is an opinion about puberty that has some negative aspects. According to this view, he mentions that adolescence includes intense stress, pessimistic thoughts and inner turmoil. The aim of this study is to examine the methods of coping with physical and mental problems encountered in adolescence. It was applied to 8 high school students between the ages of 12-19 who are studying in Yozgat. Research data were obtained by semi-structured interview, one of the qualitative data collection tools. The data obtained as a result of the interviews with the participants were analyzed with descriptive analysis. At the end of the analysis of the data, themes were created in consideration of the literature. These themes are (1) stress, (2) mental problems, (3) physical problems, (4) coping with stress, and (5) environment. In this context, it is seen that family, friends and teachers play an important role in the psychological, physical and behavioral problems of adolescents and in the solution of these problems. The application of the research to a single high school type and the fact that the number of male students is more than the number of female students are among the limitations of the research. Based on the data obtained, trainings and seminars can be given by experts to families about the physical development and psychological problems of adolescence.

The present study aimed to test if perceived pubertal timing was related to marijuana and alcohol use through deviant peer affiliation. Additionally, we examined if the deviant peer pathway was moderated by impulsiveness, gender, or both. Data were collected from 342 youth, most of whom had a family history of substance use disorder. Youth completed assessments every six months from age 13 to 16. For girls only, longitudinal analyses revealed that perceived pubertal timing was indirectly related to substance use through higher levels of deviant peer affiliation. This pathway was moderated by impulsiveness such that the association between perceived pubertal timing and deviant peer affiliation was only present for girls with average to high levels of impulsiveness. These findings elucidate a developmental pathway from perceived pubertal timing to substance use through deviant peer affiliation for high-risk girls, although low levels of impulsiveness were protective.

Adverse experiences throughout development confer risk for a multitude of negative long-term outcomes, but the processes via which these experiences are neurobiologically embedded are still unclear. Adolescence provides an opportunity to understand how these experiences impact the brain's rapidly changing structure. Two models are central to current adversity conceptualizations: a cumulative risk model, where all types of experiences are combined to represent accumulating stress, and a dimensional model, where certain features of experience (e.g., threat or deprivation) exert unique neurophysiological influence. In this registered report, we extended upon previous research by using a form of representational similarity analysis to examine whether the dimensional and cumulative risk models of adversity predict cortical thinning in frontoparietal and frontotemporal networks and volumetric changes in subcortical regions throughout adolescence. Drawing from a longitudinal sample of 179 adolescent girls (ages 10-13 years at the first wave) from Lane County, Oregon, United States, and up to four waves of follow-up data, we found that operationalizing adversity by similarity in threat and deprivation provided better prediction of brain development than similarity in overall adversity. However, these dimensions do not exhibit unique associations with developmental changes in the hypothesized brain changes. These results underscore the significance of carefully defining adversity and considering its impact on the entire brain.

The age of the onset of menstruation, termed menarche, has been declining for decades worldwide. Approximately 12% of Australian girls reach menarche between eight to 11 years of age. Current health and physical education subject guidelines from the Australian Curriculum Assessment and Reporting Authority state that puberty education should be introduced to students between year levels five to six (ages 10-12) when many have already begun puberty. To explore how girls experiencing early menarche are currently supported in Australian primary schools, semi-structured telephone interviews were conducted with 15 primary school staff from separate schools, including teachers, principals, a school services officer, and a school counsellor. Thematic analysis identified three main themes, (1) the prevalence of deficit models of early menarche and children's capacity to know; (2) gendered gatekeeping of menstruation knowledge; and (3) systemic barriers and inconsistencies in menstruation education. Our analysis complements but extends recent calls for improvements to menstruation education in Australian schools. Affirmative menstrual support practices and facilities are needed in primary schools to normalise and encourage conversations with students about menarche and menstruation irrespective of age, gender, class or culture.

Student-reported quality and coverage of school-based relationships and sex education (RSE) vary, with gender/sexual-minority and disadvantaged students reporting poorer provision. Experience of RSE among younger adolescents is under-explored. We examined student-reported RSE coverage and priorities and how coverage, and sexual-health knowledge and awareness of services, varies between students and schools. The data came from a pre-intervention survey of students aged 12-13 years within a trial of an RSE intervention involving 50 English schools. There was most coverage of basic information, such as puberty and safeguarding. There was least coverage of topics more appropriate for older students, such as sexual relationships, and topics teachers might find difficult to broach, e.g. pornography and masturbation. Girls, gay/lesbian students, students of bisexual/other sexual orientation, minority-ethnic students and students reporting lower academic commitment reported lower coverage than others. Knowledge of RSE-related topics and sexual-health services was generally low. Boys, students of bisexual/other orientation and students with higher school commitment had higher knowledge. Students of bisexual/other orientation and students of lower commitment reported lower awareness of services. Coverage and knowledge did not vary with school-level attainment or local deprivation. Future forms of RSE provision should ensure content and teaching methods meet the needs of all students.

During adolescence, increases in pubertal hormones lead to reproductive maturity as well as changes in cognitive development. Yet, little is known about how to best characterize interindividual differences in hormone concentrations. The goal of the current study was to examine the antecedents and consequences of membership in empirically derived hormone profiles. Data were drawn from 10,816 youth (48.1% female, M[subscript age] = 9.91, SD[subscript age] = 0.63) in the Adolescent Brain Cognitive Development (ABCD) study. Latent profile analysis (LPA) stratified by sex was used to derive hormone profiles using basal testosterone, dehydroepiandrosterone and estradiol (girls only). Eight profiles (four female profiles and four male profiles) were identified. They primarily represented differences in hormone levels (e.g., low hormonal milieus vs. high hormonal milieus), but also reflected discordance (e.g., high estradiol versus. high testosterone). There were limited sociodemographic differences, particularly after correcting for multiple comparisons, but youth with higher hormone milieus exhibited better inhibitory control, visuospatial processing and decision-making skills even after adjusting for age, pubertal status and demographic data. Thus, youth-centered approaches that focus on patterns of individual characteristics suggest that hormonal markers may provide unique information about associations between biological and cognitive development.

The present study tested the developmental links between maternal closeness and support and measures of depression and anxiety symptoms, and whether these links were conditioned by pubertal status. It was hypothesized that pubertal status (early) would potentiate the negative links (stronger relationships) between maternal positive parenting and developmental changes in internalizing problems in comparison to youth who mature on time or late. Four waves of self-report data were collected from 340 Czech female adolescents (Mage = 12.34 years, SD = 0.87 at W1), from 6th and 7th grades, including BMI, pubertal development, maternal closeness and support, as well as depressive and anxiety symptoms. Analyses included one-way ANOVAs by grade cohort, BMI, and pubertal status, as well as cross-lagged panel model tests, with follow-up multi-group tests. Results provided evidence of bidirectional effects between closeness and support with developmental changes in depressive symptoms, and some evidence of the same in anxiety symptoms. Multi-group tests provided no evidence of moderation effects by grade cohort, BMI groups, or pubertal status. Findings provide important evidence of how positive parenting predicted developmental changes in internalizing problems, only six months apart; they also provided important evidence that neither BMI nor pubertal status moderated the parenting-internalizing problems links.

Loneliness becomes more prevalent as youth transition from childhood into adolescence. A key underlying process may be the puberty-related increase in biological stress reactivity, which can alter social behavior and elicit conflict or social withdrawal (fight-or-flight behaviors) in some youth, but increase prosocial (tend-and-befriend) responses in others. In this article, we propose an integrative theoretical model that identifies the social, personality, and biological characteristics underlying individual differences in social--behavioral responses to stress. This model posits a vicious cycle whereby youth who respond to stress with fight-or-flight tendencies develop increasing and chronic levels of loneliness across adolescence, whereas youth who display tend-and-befriend behaviors may be buffered from these consequences. Based on research supporting this model, we propose multiple avenues for intervention to curtail the prevalence of loneliness in adolescence by targeting key factors involved in its development: social relationships, personality, and stress-induced behavioral and biological changes.

Theory and research highlight the mismatch between puberty-associated challenges and personal coping resources among youth with early actual or perceived pubertal timing. This study (N = 167; M[subscript age] = 12.41 years; 51.5% female; 77.8% White American) examined whether coping resources provided by mothers (maternal socialization of coping) exert protective or exacerbating effects on risk for depression among early-maturing youth. Results revealed that earlier perceived timing predicted higher subsequent depressive symptoms in girls with low (B = 0.40, SE = 0.15) but not high (B = -0.08, SE = 0.17) levels of engagement coping suggestions, whereas earlier perceived timing predicted higher subsequent depressive symptoms in boys with high (B = 0.40, SE = 0.17) but not low (B = -0.12, SE = 0.15) levels of engagement coping suggestions. These findings build on prior theory and research by highlighting that maternal coping suggestions may mitigate or enhance depression risk in youth who perceive themselves as early maturers; the differential effects in girls and boys suggest that the impact of these suggestions may depend on whether they are in line with gender-specific norms for coping.

This article documents the framework, central principles and curricular plan for a parent-led puberty education program facilitated with a small group of Latina adolescents. In a moment of increasing awareness of the centrality of race, puberty education has remained steeped in a colorblind framework; this parent-led program seeks to offer a counterpoint to that. The author hopes this framework helps inspire a conversation among educators, parents and youth workers about what it means to think about puberty education from the lens of race and in doing so, how we grapple meaningfully with what it means to formulate and articulate a feminist approach to puberty education for Latina girls.

This article draws on grounded theory and ethnographic fieldwork approaches and applies a political ecology of adolescent health (PEAH) framework to examine how school-going adolescent girls and their communities perceive sexual and reproductive health education (SRHE) and menstrual hygiene management (MHM) in the region. Three young girls were purposefully selected from each of 10 government-run mixed primary schools in Juba, South Sudan, as peer research evaluators (PREs) and key informants (N = 30). Each PRE interviewed and reported on three of their peers about how they talk about and manage menstruation. The findings show that political, socioeconomic, and cultural factors do influence adolescent girls' and their communities' perceptions about puberty and menstruation. In general, MHM was culturally constructed, but the results show a disproportionate emphasis on social norms rather than on SRHE, which could have long-lasting health implications for adolescent girls. There is a need for all stakeholders in education to come together to better grasp and address the obstacles young girls face in their communities and school environments. There is also a need to develop relevant training materials to assist care providers and adolescent girls to openly talk about and address sexual and reproductive health issues.

Sex and fertility education is essential to enable people to make informed choices. School is an important source of education, so we examined the current curriculum relating to sex and fertility education in England and compared it with students' accounts of their experiences. We analysed the Awarding Body GCSE science and biology specifications (for 14-16 year-olds) and the A-level biology specifications (for 16-18 year-olds), as these related to relationships, sexuality and fertility. An online survey was conducted with 221 16-17 year-old school students to evaluate their views about their sex and fertility education. We found significant variation between the specifications of the Awarding Bodies at both GCSE and A level. Most of the specifications specify sexually transmitted infections (STIs), hormonal aspects of reproduction and contraception. In the school survey, students indicated that topics such as puberty, contraception and STIs were more likely to be learnt in school. However, topics such as endometriosis, menopause and miscarriage were more likely to be learnt outside school. From both our curriculum analysis and student survey we conclude that there are significant gaps in the curriculum with many important topics being neglected.

Following the ongoing study to develop a Comprehensive Sexuality Education (CSE) curriculum for visually impaired learners in South Africa, teachers reported hesitance from parents/guardians to inform their visually impaired children about sex. As such, this study sought to explore parents/guardians' involvement in their children's psychosexual education. Five parents/guardians were engaged in a focus-group discussion. Data were analysed thematically, while home-school partnership theory underpinned this study. Parents felt confident that they had prepared their children with enough psychosexual education to make healthy sexual choices, and therefore blamed teachers, security guards, and hostel caretakers for their children's early sexual debut. However, no blame or accountability was assigned to the learners for their own sexual behaviour and decision-making. Interrogating the complexities within these socio-educational spaces suggested that there was confusion in the roles and responsibilities assumed for the capacitation of visually impaired learners with CSE. More importantly, the problem was not that parents were worried that these learners were not having safe sex, but that they should not be having sex at all now or in the future. The study suggests that a supportive, non-judgemental, and collaborative home-school partnership is necessary to recognise and guide the sexual agency of visually impaired learners.

Parents play an important role in adolescents' development of empathy. However, less understood is what dimensions of parental behavior predict changes in empathy during early adolescence and whether effects of parental behavior are moderated by pubertal timing or differ by sex. This study used data from an ethnically diverse sample of 704 youth who reported on their parents' nurturance, harsh discipline, and inter-parental conflict at age 11; on their own empathy at ages 11 and 13; and on their pubertal timing at age 13. The results showed that only parental nurturance uniquely predicted more empathy at age 13 and that this effect was stronger in females. Harsh discipline and inter-parental conflict were only concurrently associated with lower empathy at age 11. Pubertal timing did not moderate the links between parental nurturance, harsh discipline, or inter-parental conflict at age 11 and empathy at age 13.

Increasing research shows pubertal development accelerates following threats while it decelerates following deprivation. Yet, these environmental stressors are unlikely to occur in isolation. We investigated how war exposure and energetic stress impact pubertal development using data from the longitudinal Biological Pathways of Risk and Resilience in Syrian Refugee Children study. Our sample included 1,600 male and female Syrian refugee children and their caregivers who lived in temporary settlements in Lebanon. We hypothesized that (a) energetic stress suppresses pubertal development; (b) war exposure accelerates pubertal timing in boys and increases risk of menarche in girls, but only when energetic stress is low; and (c) when energetic stress is elevated, effects of war exposure on pubertal development will be attenuated. Among boys, we did not find support for Hypothesis 1, but Hypotheses 2 and 3 were supported. Exposure to morbidity/mortality threats accelerated pubertal timing; this effect was attenuated under conditions of elevated energetic stress. Among girls, we found support for Hypothesis 1, but not for Hypotheses 2 and 3. Elevated energetic stress decreased the risk of menarche in girls. Neither war exposure, nor any interactions with energetic stress, predicted risk of menarche. Sensitivity analyses revealed a significant interaction between bombing exposure and the amount of time since leaving Syria. Bombing decreased the risk of menarche, but only for girls who had left Syria four or more years prior to data collection. We discuss implications for translational efforts advocating for puberty screening in medical and mental health settings to identify trauma-exposed youth.

When working with beginning instrumentalists, many music educators emphasize executive skills specific to the mechanics of playing an instrument. However, beginning students can also benefit from focused vocal instruction as a complement to their musical growth in the instrumental setting. Because instrumental music educators may feel ill equipped to implement vocal strategies, it is important to arm instrumental music teachers with practical tools specific to students' singing voices. In this article, we share the benefits of vocal instruction in the instrumental music classroom, considerations for the changing voice, and specific strategies for applying singing activities to help students' musical development. The activities and strategies provided opportunities for students to create, perform, and respond to music in a variety of ways while developing their singing voices and strong musicianship skills and knowledge, promoting lifelong music engagement.

Puberty can be a particularly challenging time for adolescents who are transgender. Access to puberty blocking medication, commonly called 'puberty blockers', is considered an integral component of gender affirmative healthcare. Existing literature provides little insight into how parents of trans children entering into early adolescence navigate decision-making related to puberty blockers. This unique research examines parental perspectives on medical decision-making from a cohort of families with trans children who socially transitioned pre-adolescence (average age 7), and who at time of parental interview were in or approaching, early adolescence (average age 11). Data were analysed through inductive reflexive thematic analysis. Parental reflections are presented within three main themes, concern for protection of adolescent mental health and well-being, parental perspectives on adolescent consent, and managing decision-making without certainty. These findings hold relevance for healthcare policy makers, for parents of trans children, and for healthcare, social services and other professionals supporting trans adolescents and their families.

We examined the relationship between weight status, appetite regulating hormones, and mealtime behaviors among children, (5-12 years old), diagnosed with Autism Spectrum Disorder (ASD) in a cross-sectional study. All (N = 21) completed anthropometry measurements and (n = 18) provided blood samples for hormone analysis. Mealtime behavior, dietary, physical activity, puberty stage, and social impairment data were collected. Under fasting conditions, overweight/obese (OWOB) participants, (n = 6), had higher leptin concentrations (p < 0.02) and more feeding challenges (p < 0.05) than normal weight (n = 15). Higher leptin levels and disruptions in mealtime behaviors may exist among OWOB children in this study. Future longitudinal studies that examine appetite regulating hormones and mealtime behaviors may inform our understanding of the role of these markers in the development of obesity in ASD.

Internet-based platforms present vital new venues for sex education. However, research is limited on the ways adolescents utilize these resources, particularly within user-generated content contexts. This study assesses the sexual health content adolescents seek online through a qualitative, directed content analysis of 365 user-generated posts in an open sexual health community forum. An adapted version of the National Sex Education Standards, a comprehensive, evidence-based sexual health framework, was used as the schema for this data analysis. Collectively, our results highlight and confirm the importance of providing comprehensive, medically accurate sexual health information to adolescents. Our analysis further supports the need to provide information on pleasure in sexual health and well-being, as well as guidance on social and emotional aspects of sexual health, and for education to be supportive and inclusive of all individuals. Ultimately, our results can help guide effective public health interventions, including sex education efforts, aimed at promotion of adolescent sexual health by offering direct insight into adolescents' perceived information needs.

Background: Parents play an important role in shaping young people's sexual lives and behaviours with implications for their current and future sexual and reproductive health. This study examined the perspectives of rural Zimbabwean parents on young people's sexual health. Design: Semi-structured individual interviews were conducted with 19 (6 men and 13 women) participants. Setting: Interviews were conducted in a rural district in Zimbabwe. Method: Semi-structured interviews were conducted with Community Field Officers who were the parents or caregivers of teenage learners in two rural secondary schools. Transcripts were coded and thematic analysis conducted by reading, re-reading, interpretation and reflection on the coded texts. Results: Parents approached the question of young people's sexual health by placing young women's sexuality under surveillance and regulation. Puberty and female bodily changes triggered concern about heterosexual relationships informed by protectionist and moralising discourses. Abstinence and self-control were promoted as expectations for female sexuality based on cultural norms concerning purity and female virginity. Female sexual purity provided a claim to status, was differentiated from other forms of femininity and was an important cultural and economic resource. In a context of economic precarity, the institutions of marriage and bride wealth, whereby female virginity status is valued, provide opportunities for future economic security and reinforce cultural norms concerning respectability. Conclusion: Working with parents to address the ways in which gender and cultural norms operate within the local social and economic context is vital to understand the enduring processes by which young female sexuality is placed under surveillance while reinforcing gender inequalities.

Physical education (PE) has significant potential to shape how young people experience their own and others' bodies. This potential has not always been realized in positive ways and some research suggests that experiences in PE have contributed to young people's dissatisfaction with their appearances. The broad aim of this review is to provide a comprehensive understanding of body image as a pedagogical issue within PE. A narrative approach to the review is adopted that enables us to summarize, compare, explain and interpret various types of research relevant to our aim. From the databases ERIC, SCOPUS and PsycInfo, 25 articles were identified that deal with either body image in typical PE lessons or researcher-led attempts to influence students' body image (what we have termed 'pedagogic interventions'). Main findings are that: (1) PE has been presented as both part of the cause and a potential site of intervention to the problem of negative body image; (2) Researchers have based pedagogic interventions on four types of guiding principles; and (3) Researchers have made an array of recommendations for practitioners relating to gender, time, professional development and the characteristics of the pedagogical interventions. Findings are discussed in relation to broader research on body image in society and in PE with a focus on how the findings might inform further scientific practice.

Trans and non-binary youth (TNBY) face high levels of interpersonal and social adversity as well as disproportionate rates of mental health issues such as depression, self-harm and suicidal ideation. Among protective factors, context plays a key role. In addition to parental support, access to gender-affirming medical care begins to emerge as crucial for young people needed them. This paper compares, through thematic analysis, the experiences of TNBY with regard to access and experiences to care in Canada, Switzerland, England, and Australia. It identifies similarities and differences in barriers to access to care, as well as impacts of gender affirming care on young people and their well-being. The article concludes with a discussion on the importance of prompt and easier access to gender-affirming medical care, of training of professionals, and a hypothesis about the role of context in TNBY well-being.

Autistic people are over-represented at gender clinics, but there is limited research to guide clinical practice with this group. We investigated the perspectives of clinicians working with autistic patients who experience gender dysphoria. We asked clinicians about the relationship between autism and gender dysphoria, and whether they work differently with this patient group. We recruited clinicians from young person and adult gender clinics and autism services (n = 16). We analysed the interview transcripts using interpretative phenomenological analysis (IPA). The first overarching theme was clinician understanding of the intertwined experiences of patients, with four subthemes: (a) coming to an individualised understanding of autism, gender dysphoria, and mental health; (b) different ways of thinking about gender; (c) social differences as barriers and facilitators to gender comfort; (d) the challenge of sensory sensitivities and puberty. The second overarching theme was mismatch of patient and clinician communication styles and goals, with three subthemes: (a) different communication of gender needs; (b) changing clinical sessions to overcome barriers; (c) tension between clinician and patient aims and thinking styles. We conclude that autism adaptations should be made in gender settings, by increasing clinician understanding of how autism and gender dysphoria can intersect, as well as by making adjustments to clinic processes.

The purpose of this study was to investigate the effect of relative age on selected biomotoric skills of children in puberty period. The sample of this research consisted of 30 male and 30 female students who have been studying at primary schools and on 9 age period. Identity info was grounded on determining chronologic ages of participants. In this research, different test protocols had been applied to determine performances related to biomotoric skills of students. Sit and reach test to determine flexibility performance, proagility for agility test, standing long jump and vertical jump tests for measuring leg strength were applied. 10 meters speed test was applied to determine running speeds. SPSS 20.0 package programme was used for data analysis. Mann-Whitney U test was used for the comparison of two groups. Results were given as arithmetic mean and standart deviation. p < 0.05 was accepted as significant. It was determined that flexibility, agility, and standing long jump variables were significant (p < 0.05), but the difference between vertical jump and speed variables were not statistically significant (p > 0.05) in the between male and female students participated in research. It was thought that having differences in biomotoric skills of children in different birth quarters arised from children born at first quarters were able to reach earlier to biological maturation level than children born at last quarters. In order to establish a norm, it was recommended to make more similar researches with more participants and repetitions.

This study aims to analyze the effects of 6-week core training on certain biomotor abilities for footballers in the pubertal period. Accordingly, 30 male footballers who attend football courses regularly participated in the study. Footballers were divided into two groups; 15 of them were assigned to the Core Training Group (CTG) (age: 9.73 years; height: 139 cm; and body weight: 33.66 kg.) while 15 of them were assigned to the Conventional Training Group (CONTG) (age: 10.06 years; height: 139 cm; and body weight: 35.32 kg). While CONTG was applying the traditional training protocol, CTG additionally applied core strength exercises (two days a week for 10-15 min.). The selected biomotor tests were applied to both groups before and after the 6-week application. Between pre- and post-test values in the CTG, a statistically significant difference was found in flamingo balance, core stabilization balance, hand grip strength, 30 sec. abdominal crunch and 30 m sprint tests (p<0.05). In the CONTG, a statistically significant difference was found in 30-second push-up test values between pre- and post-tests (p<0.05). Comparing the pre-tests between groups, a statistically significant difference was found in flamingo balance and vertical jump tests (p<0.05). Also, comparing the post-tests, a statistically significant difference was found in core stabilization balance and vertical jump tests (p<0.05).

The purpose of this pilot study was to expand understanding of the experience of menstruation for girls in the United States and its impact in the school setting. A qualitative approach was used to gather data from focus group interviews. Descriptive content analysis was used to categorize the range and types of menstruation experiences described by 12 participants aged 12-16 years. Findings revealed four main themes: (1) learning about menstruation, (2) experiencing menstruation, (3) managing menstruation, and (4) social norms and meaning of menstruation. Participants described multiple challenges faced learning about and experiencing menstruation, especially in the school setting. Participants described the limited understanding of menstruation experiences and confusion about the use of menstrual hygiene products. Challenges experienced at school included not having adequate access to menstrual hygiene products, limited time for changing products, fear of leaking menstrual blood, and impacts on school attendance. School nurses are well-positioned to contribute to creating school environments that are supportive of menstruation.

With no standardized approach to sexuality education among Canada's 13 provinces and territories and the various curricula focusing on neurotypical and non-disabled children, educators have insufficient instruction and lack appropriate training on how to address sexuality education for children and youth with disabilities, particularly children and youth with autism spectrum disorder (ASD). This article provides the current context of sexuality education for children and youth with ASD in Canadian schools and guidance for more inclusive approaches with attention to three important areas: puberty, relationships, and gender and sexual diversity. Recommendations are offered to support more inclusive approaches to sexuality education, acknowledging that a one-size-fits-all approach is insufficient for children and youth with ASD. The recommendations focus on three goals: (a) moving beyond simple knowledge-based approaches to include skill-building; (b) including parents, autistic voices, and advocates in planning and ongoing conversations; and (c) providing supports for educators.

Based on the "Differential Susceptibility Theory," we examined whether the relationship between pubertal maturation and depressive symptoms can be moderated by individual differences in environmental sensitivity. The current article used the three-wave data collected from Japanese adolescents aged from 12 to 15 years (girls = 111, boys = 98). Consequently, a significant Sensitivity × Pubertal Development interaction was observed in 12- to 13-year-old boys, but not girls. Sensitive boys who experienced accelerated physical maturation reported decreased depressive symptoms, while those who experienced less maturation had increased depressive symptoms. The shape of the interaction supported both the "Differential Susceptibility Theory" and the "Diathesis-StressModel." Our findings suggest that sensitivity during early puberty among boys could be reconsidered as "susceptibility" rather than "vulnerability."

The thrifty phenotype and fetal overnutrition hypotheses are two developmental hypotheses that originated from the "developmental origins of health and disease" (DOHaD) perspective. The DOHaD posits that exposures experienced prenatally and early in life may influence health outcomes through altering form and function of internal organs related to metabolic processes. Obesity risk and early pubertal timing might be influenced by similar mechanisms. The thrifty phenotype hypothesis is primarily characterized by experiencing a deprivation of nutrients during gestation paired with an energy rich postnatal environment. The fetal overnutrition hypothesis says that obesity experienced prenatally will be associated with increased lifetime risk of obesity in the offspring. Both hypotheses were tested by examining developmental pathways from genetic and prenatal risk through early growth trajectories (birth to 7 years) to pubertal timing at age 11 years. Participants included 361 children adopted at birth (57% male; 57% non-Hispanic White, 11% Black, 9% Hispanic; adoptive family income Mdn = $70,000-$100,000, birth family income Mdn = <$15,000). Associations between boys' childhood body mass index (BMI) and pubertal timing were confounded by genetics, prenatal risk, and early growth. The thrifty phenotype hypothesis was partially supported for boys' childhood BMI (at ages 4 to 7 years). Both hypotheses were partially supported for girls' childhood BMI but not pubertal timing. A novel Gene x Prenatal Risk interaction showed that genetic risk predicted girls' childhood BMI most strongly at adequate compared with at excessive levels of gestational weight gain.

Individuals with autism spectrum disorder (ASD) may demonstrate atypical autonomic (ANS) responses; however, research remains inconsistent. This study examined parasympathetic response during social evaluation in 241 youth (10-13 years) with ASD (n = 138) or typical development (TD; n = 103). Diagnosis, age, pubertal development, and body mass index (BMI) were hypothesized to be associated with ANS function. Linear mixed effects models demonstrated lower RSA in ASD relative to TD in a base model with no covariates. However, when accounting for differences in BMI, there was no evidence of atypical parasympathetic regulation in youth with ASD. As lower parasympathetic regulation may increase susceptibility for a number of conditions, it will be important to elucidate the link between BMI and the ANS, especially in ASD.

The purpose of this study was to examine whether school discipline sanctions issued to female students are attributed to their racial background and developmental status and if this relation differs by teacher's racial/ethnic background and discipline philosophy. Drawing from a sample of 515 practicing educators from the United States, the authors used an experimental design to examine if teacher's discipline decision-making differed by student's race, student's developmental status, and teacher's racial/ethnic background and discipline philosophy. Results suggest that teacher's racial/ethnic background and discipline philosophy were the most salient predictors of discipline severity. Implications for future research on school discipline and Black girls are discussed.

Composing Territory is a research project with two main aims. The first aim is to identify optimal composition and arrangement techniques for choral works written for female singers from various linguistic backgrounds in the Northern Territory whose voices are undergoing pubertal changes. The second aim is the creation of twelve choral compositions plus an accompanying teaching resource, to provide sequential delivery appropriate to the educational context of the region, wherein the majority of choral educators have no music training. The diverse and transient nature of the Northern Territory's population and the lack of education training and resources for choral delivery make traditional choral works inaccessible and tonal homogeneity of choirs unlikely. By changing the way we compose choral works it may be possible to ensure student learning continues through the period of female vocal change, achieve more homogenous sounds from linguistically diverse choristers, and successfully establish choral blend. Underpinning the compositional process with pedagogical considerations of linguistic differences and pubertal changes delivered through appropriate teaching strategies and resources will be significant outcomes of this projects. These outcomes could ensure non-music specialists are better equipped for choral delivery and student learning continues throughout voice change processes unhindered by individual linguistic background.

In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic dimensions to the segmental, prosodic, lexical, and morphosyntactic dimensions of L2 proficiency. Overall, auditory processing was a primary determinant of a range of participants' proficiency scores, even after biographical factors (experience, age) were controlled for. The link between audition and proficiency was especially clear for L2 learners who had passed beyond the initial phase of immersion (length of residence > 1 year). The findings suggest that greater auditory processing skill benefits post-pubertal L2 learners immersed in naturalistic settings for a sufficient period of time by allowing them to better utilize received input, which results in greater language gains and leads to more advanced L2 proficiency in the long run (similar to L1 acquisition).

This study employed semi-structured interviews and Interpretative Phenomenological Analysis to explore experiences of on-time maturation in nine adolescent ballet dancers from across three vocational ballet schools in the United Kingdom. Two themes were identified as central to their experiences: 'A right and a wrong way to grow', and fitting in and moving forward. Instead of perceiving themselves as 'average' and experiencing a relatively easy pubertal transition, on-time dancers described unique challenges associated with a fluctuation between fitting in and not fitting in within their social context. The implications of on-time maturation in this context are complex and do not appear to follow the same trajectory as early maturing ballet dancers nor on-time non-dancers.

The sex bias in autism diagnosis suggests the involvement of sex-specific endocrine mechanisms during prenatal development, but these hormones affect health throughout life. Therefore, the current study examined the association of autism and autistic traits with conditions and symptoms related to the sex-steroid system in adult women. In total, 1230 women (361 autistic), aged 15-77 years, reported on autistic traits and medical history. Medical diagnoses and symptoms were grouped by unsupervised factor analysis, and associations with autism diagnosis and autistic traits were explored. Higher rates of reproductive system diagnoses (odds ratio = 1.035, p = 0.024), prediabetes symptoms (odds ratio = 1.319, p = 0.001), irregular puberty onset (odds ratio = 1.458, p = 0.009), and menstrual length (odds ratio = 1.368, p = 0.034) and lower rates of metabolic and vascular conditions (odds ratio = 0.654, p = 0.013) were associated with diagnosis. Reproductive system diagnoses ([beta] = 0.114, p = 0.000), prediabetes symptoms ([beta] = 0.188, p = 0.000), menstrual length ([beta] = 0.071, p = 0.014), irregular puberty onset ([beta] = 0.149, p = 0.000), excessive menstruation symptoms ([beta] = 0.097, p = 0.003), and hyperandrogenism symptoms ([beta] = 0.062, p = 0.040) were also associated with autistic traits. Many of the conditions and symptoms found to be associated with autism or autistic traits are also related to conditions of steroid hormones and, specifically, the sex-steroid system. The study suggests an important role for steroids in autistic women, beyond prenatal development. Clinical implications are discussed.

The following article presents a paradigm shift in order to engage in more expansive pedagogy in the teaching of puberty; specifically, to create a more inclusive and affirming space for LGBTIQA+ youth. Attention to LGBTQIA+ populations has slowly been integrated into many areas of research, theory, and teaching in psychology and related disciplines. While positive strides have been made, lessons on adolescent psychology, and puberty specifically, remain stuck in older binary models. The following is an examination of the dominant approach utilized for teaching puberty in senior-level high school and early undergraduate adolescent psychology courses, a critique of that model, as well as a presentation of a new model for teaching pubertal development. A proposed Model of Expansive Pubertal Understanding is shared here, and allows for a fuller, more accurate, and more positive, approach to pubertal development. It is further proposed that the information shared in this model be infused much earlier in youth education, and through a breadth of disciplines, to effectively promote psychological and physical wellbeing among children and youth of diverse genders, sexes, and sexualities.

This article reports on an ethnographic study to understand the practices of sexuality education (SE) in relation to what young girls want to learn in a primary school Ethiopia. This is done by means of school observations, FGD with female students and interviews with SE teachers. The study shows the observed SE focuses mainly on issues of HIV/AIDS and abstinence, which left the interviewed girl's questions unanswered. The latter were concerned with learning about sexual practices and consequences, and bodily functions. The findings also show girls demand more inward-looking SE that addresses and could solve within-school issues. The findings suggest that SE should bring educational needs of students to the fore, instead of dramatising. Our results also shed new light on the critical approaches -- despite their focus on abstinence -- also advocate gender-equality and discuss body-changes in a radical manner, appearing to challenge unquestioned traditions and the general gender-order.

We used latent growth curve analysis to extend research on associations between early puberty and adverse peer relations by examining the role of pubertal timing in the developmental trajectories of peer victimization and offending from early- to mid-adolescence. We made use of three-wave longitudinal data collected annually from a cohort of Swedish adolescents (N = 1,515, 51% girls, [X-bar] age at T1 = 13.0 years). The results revealed negative developmental trends for peer victimization and offending. Early pubertal timing was linked to higher initial levels and a steeper decrease of peer victimization and offending. The only effect of pubertal timing that differed between the genders was that the initial level of offending was stronger for boys than girls. In conclusion, the negative impact of early pubertal timing on peer victimization and offending occurs in the early stages of adolescence and disappears thereafter.

Participation in physical activity (PA) tends to decline between childhood and adolescence, and in Australia the bulk of this decline has been shown to occur in the domain of non-organised PA (e.g. active play, informal sports). A better understanding of the reasons for the decline in non-organised PA may support strategies to counter barriers and strengthen enablers of participation. This study aimed to explore the stories of young adults who withdrew from non-organised PA and overall PA between 11y and 15y. Specifically, we sought to explore social norms related to non-organised PA during adolescence, and barriers and enablers of participation. Participants were young adults (18-22y) who were recruited from undergraduate, vocational and special entrance classes, as well as two churches in the Illawarra region, Australia. Recruitment was stratified by sex and socioeconomic status. Data collection occurred via semi-structured interviews with embedded Life History Calendars (n = 22). Thematic analysis was supported by concept and pattern coding. Findings revealed that social norms were related to an interplay of adult modelling/influence, concerns about being childish, puberty, identity development, adult choices and responsibilities, and changing life circumstances. Barriers to participation centred on fears of being different, bullying, peer judgement and rejection. Enablers of participation included safe people and places, accessible games (e.g. handball/foursquare) and, for girls, having an identity that supported challenging gender norms. Future PA promotion strategies may involve 'reframing' childhood activities to be appropriate for adolescents, and emphasising identity-congruent types of PA (e.g. active video games, drama games). Such strategies may be implemented in a similar style to after-school intramural sports to allow youth to participate despite potential changes in their life circumstances during adolescence.

Recent research has suggested that the pubertal period provides an opportunity for recalibrating the stress-responsive systems in youth whose responses to stress have been altered by early adversity. Such recalibration may have cascading effects that affect brain and behavioral development. In this article, we consider a large, cross-species literature to demonstrate the potential importance of pubertal stress recalibration for understanding the development of psychopathology following early deprivation by caregivers. We review the evidence for recalibration of the hypothalamic-pituitary-adrenal axis in humans, examine research on rodents that has established mechanisms through which stress hormones affect brain structure and function, and summarize the literature on human neuroimaging to assess how these mechanisms may translate into changes in human behavior. Finally, we suggest ideas for elucidating the consequences of pubertal stress recalibration that will improve our understanding of adaptive and maladaptive adolescent behavior following early adversity.

Background: People with disability have the same sexual and reproductive health needs and rights as people without disability, yet experience considerable barriers in accessing information and services. The Reproductive and Family Health Association of Fiji, Family Planning Australia, and disability stakeholders implemented a comprehensive sexuality education (CSE) disability inclusion project to increase access for students with disability to age-appropriate sexuality education. Method: A train the trainer model was utilised, whereby staff and disability stakeholders undertook competency-based training on delivering sexuality education to teachers and people with disability, then trained and supported teachers working in special disability schools to provide sexuality education to students. An evaluation explored the acceptability and effectiveness of the project, utilising baseline and endline surveys and interviews. Findings: From 2016 to 2018, the CSE disability project reached teachers and students in nine special disability schools in Fiji. At project completion, teachers reported increased confidence overall in teaching about sexuality and relationships, and students demonstrated increased knowledge regarding puberty and body changes. Interview findings suggested the project contributed to overcoming silence and stigma for people with disability and promoting safety for young people. Conclusion: Age- and developmentally appropriate sexuality education for people with disability is essential for equipping them with necessary knowledge and skills. The CSE disability project utilised a collaborative, capacity building approach to co-design and implement sexuality education in special disability schools in Fiji. With commitment from stakeholders, this could be sustained and expanded to support students with disability in achieving optimal sexual and reproductive health.

The purpose of this study was to describe the voice change and voice part assignment of male middle school choir members. Volunteers (N = 92) were recruited from three public middle school choral programs (Grades 6-8). Participants were audio-recorded performing simple vocal tasks in order to assess vocal range and asked to share the music they were currently singing in class. Results revealed 23.91% of participants' voices could be categorized as unchanged, 14.13% as Stage 1, 3.26% as Stage 2, 10.87% as Stage 3, 26.09% as Stage 4, and 21.74% as Stage 5. The majority of sixth-grade participants were classified as unchanged or in Stage 1 of the voice change and the majority of eighth-grade participants were classified in Stages 4 to 5 of the voice change. Of the participants labeled "tenors" in their choir, over 60% were classified as either unchanged voices or in Stage 1 of the voice change.

The importance of body change during the adolescence has been well documented within the literature. In this study, gender differences were investigated in the use of adolescents' perceptions of all body images, body parts and functions, and strategies of coping with body image. Data were collected from 710 first-year students from different high school types with an age range of 14-15. The results indicated that body image of female adolescents showed a significant difference in negative direction compared to male adolescents. Males showed a significant positive difference compared to girl adolescents. Results also demonstrated that male adolescents showed significant positive difference in the use of the avoidance strategy compared to female adolescents. Regarding body image coping strategies, there was a significant positive difference in the use of the avoidance strategy in favor of males. The results with implications for future research and practice are addressed.

Adolescence is a time of exceptional physical health juxtaposed against significant psychosocial and weight-related problems. The study included 241, 10-to-13-year-old youth with autism spectrum disorder (ASD, N = 138) or typical development (TD, N = 103). Standardized exams measured pubertal development, height (HT), weight (WT), heart rate (HR), blood pressure (BP) and Body Mass Index (BMI). Analysis of Variance showed no significant between-group differences for HT, WT, HR, or BP (all p > 0.05). There was a significant difference in BMI-percentile between the groups (F(1,234) = 6.05, p = 0.01). Using hierarchical linear regression, significant predictors of BMI-percentile included diagnosis, pubertal stage and socioeconomic status. Pre-to-early pubescent children with ASD evidence higher BMI percentiles compared to youth with TD suggesting they may be at heightened risk for weight-related health concerns.

Literature has documented inflated rates of features associated with autism spectrum (AS) in clinic referred, gender diverse young people. This study examined scores on the Social Responsiveness Scale, Second Edition (SRS-2) over time in a group of clinic referred, gender diverse adolescents accessing gonadotropin-releasing hormone analogues (GnRHa) to suppress puberty. Primary caregivers of 95 adolescents presenting to the Gender Identity Development Service (GIDS) completed the SRS-2 prior to receiving endocrine input (mean age: 13.6 ± SEM: 0.11) and after approximately one year of accessing GnRHa (mean age: 14.6 ± SEM: 0.13). No significant differences in SRS-2 scores over time and between birth assigned sex were found. No interactions between time and birth assigned sex were established for SRS-2 subscales or total scores.
