RESUMEN

Adolescence is marked by the onset of puberty, which is associated with an increase in mental health difficulties, particularly in girls. Social and self-referential processes also develop during this period: adolescents become more aware of others' perspectives, and judgements about themselves become less favourable. In the current study, data from 119 girls (from London, UK) aged 9-16 years were collected at two-time points (between 2019 and 2021) to investigate the relationship between puberty and difficulties in mental health and emotion regulation, as well as the role of self-referential and social processing in this relationship. Structural equation modelling showed that advanced pubertal status predicted greater mental health and emotion regulation difficulties, including depression and anxiety, rumination and overall difficulties in emotion regulation, and in mental health and behaviour. Advanced pubertal status also predicted greater perspective-taking abilities and negative self-schemas. Exploratory analyses showed that negative self-schemas mediated the relationships between puberty and rumination, overall emotion regulation difficulties, and depression (although these effects were small and would not survive correction for multiple comparisons). The results suggest that advanced pubertal status is associated with higher mental health and emotion regulation problems during adolescence and that negative self-schemas may play a role in this association. RESEARCH HIGHLIGHTS: This study investigates the relationship between puberty, mental health, emotion regulation difficulties, and social and self-referential processing in girls aged 9-16 years. Advanced pubertal status was associated with worse mental health and greater emotion regulation difficulties, better perspective-taking abilities and negative self-schemas. Negative self-schemas may play a role in the relationships between advanced pubertal status and depression, and advanced pubertal status and emotion regulation difficulties, including rumination.

RESUMEN

The evidence base for psychological benefits of GnRHA for adolescents with gender dysphoria (GD) was deemed "low quality" by the UK National Institute of Health and Care Excellence. Limitations identified include inattention to clinical importance of findings. This secondary analysis of UK clinical study data uses Reliable and Clinically Significant Change approaches to address this gap. The original uncontrolled study collected data within a specialist GD service. Participants were 44 12-15-year-olds with GD. Puberty was suppressed using "triptorelin"; participants were followed-up for 36 months. Secondary analysis used data from parent-report Child Behavior Checklists and Youth Self-Report forms. Reliable change results: 15-34% of participants reliably deteriorated depending on the subscale, time point and parent versus child report. Clinically significant change results: 27-58% were in the borderline (subclinical) or clinical range at baseline (depending on subscale and parent or child report). Rates of clinically significant change ranged from 0 to 35%, decreasing over time toward zero on both self-report and parent-report. The approach offers an established complementary method to analyze individual level change and to examine who might benefit or otherwise from treatment in a field where research designs have been challenged by lack of control groups and low sample sizes.

RESUMEN

Recent opposing trends towards earlier physical maturation and later social maturation present a conundrum of apparent biological-social mismatch. Here we use life history analysis from evolutionary ecology to identify forces that drive these shifts. Together with findings in developmental science, our life history analysis indicates that adolescence is a distinctive period for biological embedding of culture. Ethnographic evidence shows that mass education is a novel feature of the globalizing cultural configurations of adolescence, which are driven by transformations in labour, livelihood and lifestyle. Evaluation of the life history trade-offs and sociocultural ecologies that are experienced by adolescents may offer a practical basis for enhancing their development.

RESUMEN

Adolescent growth and social development shape the early development of offspring from preconception through to the post-partum period through distinct processes in males and females. At a time of great change in the forces shaping adolescence, including the timing of parenthood, investments in today's adolescents, the largest cohort in human history, will yield great dividends for future generations.

RESUMEN

Earlier pubertal onset has been associated with increased disordered eating symptoms in cisgender girls. Although this finding has been replicated across studies of disordered eating, most studies have focused on white samples. The lack of studies is surprising given that early pubertal timing may impact disordered eating risk in Black and Latinx girls differently due to trends of earlier pubertal onset in these groups and increased stressors related to interpersonal and structural racism and economic marginalization. Current methods of examining pubertal timing among Black and Latinx girls may also not fully capture their experience. Contextual factors (e.g., neighborhood and school racial/ethnic composition) may influence how minoritized girls both perceive and are affected by their pubertal timing. Moreover, factors such as ethnic-racial identity development and experiences of discrimination may be important mechanisms explaining the association between pubertal timing and disordered eating risk. This paper aims to provide a brief overview of studies examining pubertal timing and disordered eating risk among Black and Latinx girls in the US and to discuss recommendations for future research that integrate contextual factors in the examination of pubertal timing and its effects. PUBLIC SIGNIFICANCE: Early pubertal timing has been associated with increased risk of disordered eating symptoms among cisgender girls; however, studies have been limited due to the use of predominantly white samples. The article provides a brief overview of findings related to pubertal timing effects among Black and Latinx girls, discusses considerations for the measurement of pubertal timing, and highlights the need for inclusion of contextual factors in future research.

RESUMEN

In this essay, we consider the clinical and ethical implications of puberty blockers for pediatric gender dysphoria through the lens of "the child's right to an open future," which refers to rights that children do not have the capacity to exercise as minors, but that must be protected, so they can exercise them in the future as autonomous adults. We contrast the open future principle with the beliefs underpinning the gender affirming care model and discuss implications for consent. We evaluate claims that puberty blockers are reversible, discuss the scientific uncertainty about long-term benefits and harms, summarize international developments, and examine how suicide has been used to frame puberty suppression as a medically necessary, lifesaving treatment. In discussing these issues, we include relevant empirical evidence and raise questions for clinicians and researchers. We conclude that treatment pathways that delay decisions about medical transition until the child has had the chance to grow and mature into an autonomous adulthood would be most consistent with the open future principle.

RESUMEN

AIM: Concerns have been raised regarding the impact of medications that interrupt puberty, given the magnitude and complexity of changes that occur in brain function and structure during this sensitive window of neurodevelopment. This review examines the literature on the impact of pubertal suppression on cognitive and behavioural function in animals and humans. METHODS: All studies reporting cognitive impacts of treatment with GnRH agonists/antagonists for pubertal suppression in animals or humans were sought via a systematic search strategy across the PubMed, Embase, Web of Science and PsycINFO databases. RESULTS: Sixteen studies were identified. In mammals, the neuropsychological impacts of puberty blockers are complex and often sex specific (n = 11 studies). There is no evidence that cognitive effects are fully reversible following discontinuation of treatment. No human studies have systematically explored the impact of these treatments on neuropsychological function with an adequate baseline and follow-up. There is some evidence of a detrimental impact of pubertal suppression on IQ in children. CONCLUSION: Critical questions remain unanswered regarding the nature, extent and permanence of any arrested development of cognitive function associated with puberty blockers. The impact of puberal suppression on measures of neuropsychological function is an urgent research priority.

RESUMEN

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.

RESUMEN

Beyond NICE: Updated Systematic Review on the Current Evidence of Using Puberty Blocking Pharmacological Agents and Cross-Sex-Hormones in Minors with Gender Dysphoria Abstract: Objective: The suppression of physiological puberty using puberty-blocking pharmacological agents (PB) and prescribing cross-sex hormones (CSH) to minors with gender dysphoria (GD) is a current matter of discussion, and in some cases, PB and CSH are used in clinical practice for this particular population. Two systematic reviews (one on PB, one on CSH treatment) by the British National Institute for Clinical Excellence (NICE) from 2020 indicated no clear clinical benefit of such treatments regarding critical outcome variables. In particular, these two systematic NICE reviews on the use of PB and CSH in minors with GD detected no clear improvements of GD symptoms. Moreover, the overall scientific quality of the available evidence, as discussed within the above-mentioned two NICE reviews, was classified as "very low certainty" regarding modified GRADE criteria. Method: The present systematic review presents an updated literature search on this particular topic (use of PB and CSH in minors with GD) following NICE principles and PICO criteria for all relevant new original research studies published since the release of the two above-mentioned NICE reviews (updated literature search period was July 2020-August 2023). Results: The newly conducted literature search revealed no newly published original studies targeting NICE-defined critical and important outcomes and the related use of PB in minors with GD following PICO criteria. For CSH treatment, we found two new studies that met PICO criteria, but these particular two studies had low participant numbers, yielded no significant additional clear evidence for specific and clearly beneficial effects of CSH in minors with GD, and could be classified as "low certainty" tfollowing modified GRADE criteria. Conclusions: The currently available studies on the use of PB and CSH in minors with GD have significant conceptual and methodological flaws. The available evidence on the use of PB and CSH in minors with GD is very limited and based on only a few studies with small numbers, and these studies have problematic methodology and quality. There also is a lack of adequate and meaningful long-term studies. Current evidence doesn't suggest that GD symptoms and mental health significantly improve when PB or CSH are used in minors with GD. Psychotherapeutic interventions to address and reduce the experienced burden can become relevant in children and adolescents with GD. If the decision to use PB and/or CSH is made on an individual case-by-case basis and after a complete and thorough mental health assessment, potential treatment of possibly co-occurring mental health problems as well as after a thoroughly conducted and carefully executed individual risk-benefit evaluation, doing so as part of clinical studies or research projects, as currently done in England, can be of value in terms of generation of new research data. The electronic supplement (ESM) 1 is an adapted and abreviated English version of this work.

RESUMEN

BACKGROUND: Undergoing puberty ahead of peers ('earlier pubertal timing') is an important risk factor for mental health problems during early adolescence. The current study examined pathways between pubertal timing and mental health via connectivity of neural systems implicated in emotional reactivity and regulation (specifically corticolimbic connections) in 9- to 14-year-olds. METHOD: Research questions were examined in the Adolescent Brain Cognitive Development (ABCD) Study, a large population representative sample in the United States. Linear mixed models examined associations between pubertal timing and resting-state corticolimbic connectivity. Significant connections were examined as potential mediators of the relationship between pubertal timing and mental health (withdrawn depressed and rule-breaking) problems. Exploratory analyses interrogated whether the family environment moderated neural risk patterns in those undergoing puberty earlier than their peers. RESULTS: Earlier pubertal timing was related to decreased connectivity between limbic structures (bilateral amygdala and right hippocampus) and the cingulo-opercular network, left amygdala and somatomotor (mouth) network, as well as between the left hippocampus and ventral attention network and visual network. Corticolimbic connections also mediated the relationship between earlier pubertal timing and increased withdrawn depressed problems (but not rule-breaking problems). Finally, parental acceptance buffered against connectivity patterns that were implicated in withdrawn depressed problems in those undergoing puberty earlier than their peers. CONCLUSION: Findings highlight the role of decreased corticolimbic connectivity in mediating pathways between earlier pubertal timing and withdrawn depressed problems, and we present preliminary evidence that the family environment may buffer against these neural risk patterns during early adolescence.

RESUMEN

This exploratory study examined the relation between pubertal timing and dimensions of ethnic-racial identity among adopted Korean Americans raised transracially in White families. The study also examined whether internalized racism moderated the association between pubertal timing and ethnic-racial identity. Adopted Korean American adolescents (N = 202; 108 females; ages 13-19 years) completed measures of pubertal development, ethnic-racial identity, and internalized racism in 2007. There was no significant main effect of pubertal timing for either male or female adolescents. Internalized racism moderated the relation between pubertal timing and ethnic-racial identity clarity (B = -.16, p = .015) among male adolescents. Specifically, earlier pubertal timing was significantly associated with lower ethnic-racial identity clarity for male adolescents with higher levels of internalized racism.

RESUMEN

Variations in pubertal timing and tempo have relevance to psychosocial development. Accounting for pubertal timing, tempo, and psychosocial development simultaneously in a model remains challenging. This study aimed to document the typology of pubertal development in a cohort of Taiwanese adolescent boys and then to examine how the associations between psychosocial variables across time vary by the patterns of pubertal development. A group of adolescent boys (n = 1,368) reported pubertal signs and psychosocial variables for 3 years since seventh grade. The growth mixture model revealed three major classes of pubertal transition: average pubertal growth, late-onset with rapid catch-up, and late-onset with slow catch-up. In a cross-lagged panel model, the multigroup analysis found the regression coefficients mostly invariant across all three classes, except those between deviant behavior and subsequent changes in depressive symptoms that were significantly positive only in the late-onset with slow catch-up group. Adolescent boys in this group were estimated to have the highest marginal level of depressive symptoms and deviant behavior in ninth grade among the three classes. Our study highlights the heterogeneity in boys' pubertal development and the role of the pubertal development pattern in their psychosocial development.

RESUMEN

Across nonhuman species, pubertal timing is affected by the social environment, with consequences for reproductive success and behavior. In human beings, variations in pubertal timing have not been systematically examined in relation to social environmental antecedents, although their psychological consequences are well documented. This paper focuses on links in human beings between pubertal timing and the childhood social environment, with several sections: A review of studies relating pubertal timing to the family context, a key aspect of the social environment; challenges in studying the issue; and opportunities for future work that takes advantage of and creates links with evidence in other species. The review shows that pubertal timing in girls is accelerated by adversity in aspects of the early family social context, with effects small in size; data in boys are not sufficient to enable conclusions. Inferences from existing studies are limited by variations in conceptualizations and measurement of relevant aspects of puberty and of the family social environment, and by methodological issues (e.g., reliance on existing data, use of retrospective reports, nonrandom missing data). Open questions remain about the nature, mechanisms, and specificity of the links between early family social environment and pubertal timing (e.g., form of associations, consideration of absence of positive experiences, role of timing of exposure). Animal studies provide a useful guide for addressing these questions, by delineating potential hormonal mechanisms that underlie links among social context, pubertal timing, and behavior, and encouraging attention to aspects of the social environment outside the family, especially peers.

RESUMEN

Adolescent females are at elevated risk for the development of depression. In this study, we addressed two questions: Are pubertal hormones associated with adolescent mental health? Might this association depend on pubertal development? We tested the hypothesis that estradiol, which has been associated with adolescent social sensitivity, might interact with pubertal stage to predict depression risk at three time points in ninth and tenth grade. Hormones and pubertal development were measured ninth-grade females. Linear regression analyses were used to predict fall ninth-grade (N = 79), spring ninth-grade (N = 76), and spring tenth-grade (N = 67) Children's Depression Inventory (CDI) scores. The hypothesized model was not statistically significant, but exploratory analyses revealed that two- and three-way interactions incorporating estradiol, puberty (stage and perceived onset), and cortisol predicted current and future CDI scores. Our exploratory model did not predict changes in CDI but did account for future (spring of ninth grade) CDI scores. Specifically, estradiol was positively correlated with fall and spring ninth-grade depressive symptoms in participants with high cortisol who also reported earlier stages and later perceived onset of pubertal development. These findings suggest that hormones associated with sensitivity to the social environment deserve consideration in models of adolescent depression risk.

RESUMEN

OBJECTIVE: Previous empirical research on pubertal development among Black boys is limited. The present study examined the ethnic-racial composition of neighborhoods as a moderator in the relation between pubertal indicators and depressive symptoms among a nationally representative sample of African American and Caribbean Black boys. METHOD: The present study utilized the male sample (N = 559) from the National Survey of American Life Adolescent sample (Jackson et al., 2004). The sample consists of 395 African American and 164 Caribbean Black boys ages 13-17 years who completed measures of relative pubertal timing, voice changes, pubic hair growth, and depressive symptoms. RESULTS: The results indicate that Black boys with early developing hair growth who lived in neighborhoods with higher percentages of Black residents had higher depressive symptoms compared to their early developing counterparts in neighborhoods with fewer Black residents. African American males with early developing hair growth had higher depressive symptoms compared to Caribbean Black males with early developing hair growth regardless of neighborhood context. CONCLUSION: Early pubertal timing is a risk for African American boys' mental health regardless of neighborhood context. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMEN

BACKGROUND: Puberty is a biologically and psychologically unstable period, and pubertal changes differ by sex. However, most previous studies on pubertal timing and suicide have focused on girls. This study investigated the association between early spermarche and suicide attempts in boys. METHODS: We analyzed a nationally representative sample of Korean adolescents (The Korea Youth Risk Behavior Web-Based Survey, KYRBS) that included approximately 35,000 boys annually from 2011 to 2015. Pubertal timing in boys was defined by spermarche. Complex sampling logistic regression analyses were performed to evaluate the odds ratios (ORs) for suicide attempts between the early and average spermarche groups. RESULTS: The ORs for suicide attempts in boys with early spermarche were significantly higher than those in boys with average spermarche after adjustment for age, perceived stress, depressive symptoms, and suicidal ideation. The ORs from 2011 to 2015 were as follows: 1.782 (P < 0.001), 1.490 (P = 0.002), 1.693 (P < 0.001), 1.541 (P = 0.001), and 1.393 (1.024-1.895; P = 0.035), respectively. CONCLUSION: These findings suggest that early pubertal timing is a risk factor for suicide attempts in Korean boys after adjustment for depressive symptoms, perceived stress, and suicidal ideation, which have been previously reported as risk factors for suicide attempts. Therefore, careful attention should be paid to the prevention of suicide in boys who experience early spermarche in Korea.

RESUMEN

OBJECTIVE: Evidence stemming largely from retrospective studies suggests that childhood adversity (CA) is associated with earlier age at menarche, a marker of pubertal timing, among girls. Little is known about associations with pubertal tempo among boys or racial/ethnic minorities. We examined the association between CA and timing and tempo of pubertal development among boys and girls. METHODS: The Boricua Youth Study is a longitudinal study of Puerto Rican youth residing in the San Juan metro area in Puerto Rico and the South Bronx, New York. CA was based on caretaker reports of parental loss and parental maladjustment and youth reports of child maltreatment and exposure to violence. Youth completed the Pubertal Development Scale (PDS) yearly for 3 years. In linear mixed models stratified by sex, we examined the association between CA and pubertal timing and tempo, adjusting for site, socioeconomic status, and age. RESULTS: Among the 1949 children who were 8 years or older by wave 3, cumulative CA was associated with higher PDS scores among girls compared with girls not exposed to CA (PDS score: 2.63 [95% confidence interval {CI} = 2.55-2.71] versus 2.48 [95% CI = 2.37-2.58]). In contrast, among boys, experiencing adversities was associated with lower pubertal developmental stage or later timing (PDS: 1.77 [95% CI = 1.67-1.87] versus 1.97 [95% CI = 1.85-2.10]) compared with those not exposed to adversities. CONCLUSIONS: Associations between CA and pubertal development may vary by sex. Understanding the etiological role of adversities on pubertal development and identifying targets for intervention are of utmost importance in ameliorating the impact of CA on child health.

RESUMEN

BACKGROUND: Cross-sectional evidence suggests females in late adolescence exhibit higher rates of post-traumatic stress symptoms (PTSS) than males and younger age groups. However, longitudinal evidence is limited, and underlying factors are not well understood. We investigated the emergence of sex differences in PTSS from childhood to adolescence in a large, longitudinal UK cohort, and tested whether these could be explained by overlap between PTSS and depressive symptoms, or onset of puberty. METHODS: Trauma exposure and PTSS were assessed at ages 8, 10, 13 (parent-report) and 15 (self-report) years in a sub-sample of 9966 children and adolescents from the ALSPAC cohort-study. Analyses of PTSS focused on those who reported potential trauma-exposure at each time-point (ranged from n = 654 at 15 years to n = 1231 at 10 years). Age at peak-height velocity (APHV) was used as an indicator of pubertal timing. RESULTS: There was no evidence of sex differences in PTSS at ages 8 and 10, but females were more likely to show PTSS at ages 13 (OR 1.54, p = 0.002) and 15 (OR 2.04, p = .001), even once symptoms related to depression were excluded. We found little evidence that the emergence of sex differences was related to pubertal timing (as indexed by APHV). CONCLUSIONS: Results indicate that females show higher levels of PTSS in adolescence but not during childhood. The emergence of this sex difference does not seem to be explained by overlap with depressive symptoms, while the influence of pubertal status requires further investigation.

RESUMEN

Experiments in male rodents demonstrate that sensitivity to the organizational effects of steroid hormones decreases across the pubertal window, with earlier androgen exposure leading to greater masculinization of the brain and behavior. Similarly, some research suggests the timing of peripubertal exposure to sex steroids influences aspects of human psychology, including visuospatial cognition. However, prior studies have been limited by small samples and/or imprecise measures of pubertal timing. We conducted 4 studies to clarify whether the timing of peripubertal hormone exposure predicts performance on male-typed tests of spatial cognition in adulthood. In Studies 1 (n = 1095) and 2 (n = 173), we investigated associations between recalled pubertal age and spatial cognition in typically developing men, controlling for current testosterone levels in Study 2. In Study 3 (n = 51), we examined the relationship between spatial performance and the age at which peripubertal hormone replacement therapy was initiated in a sample of men with Isolated GnRH Deficiency. Across Studies 1-3, effect size estimates for the relationship between spatial performance and pubertal timing ranged from. -0.04 and -0.27, and spatial performance was unrelated to salivary testosterone in Study 2. In Study 4, we conducted two meta-analyses of Studies 1-3 and four previously published studies. The first meta-analysis was conducted on correlations between spatial performance and measures of the absolute age of pubertal timing, and the second replaced those correlations with correlations between spatial performance and measures of relative pubertal timing where available. Point estimates for correlations between pubertal timing and spatial cognition were -0.15 and -0.12 (both p < 0.001) in the first and second meta-analyses, respectively. These associations were robust to the exclusion of any individual study. Our results suggest that, for some aspects of neural development, sensitivity to gonadal hormones declines across puberty, with earlier pubertal hormone exposure predicting greater sex-typicality in psychological phenotypes in adulthood. These results shed light on the processes of behavioral and brain organization and have implications for the treatment of IGD and other conditions wherein pubertal timing is pharmacologically manipulated.

RESUMEN

As a period of heightened plasticity, puberty may provide a window of opportunity for recalibration of the hypothalamic-pituitary-adrenal (HPA) axis to current conditions. Our group has recently documented evidence for pubertal recalibration of HPA axis reactivity among children internationally adopted as infants from institutions into supportive, well-resourced homes. As a first step at examining potential mechanisms by which puberty may facilitate recalibration of the HPA axis, the current study assessed whether previously-institutionalized (PI) children differed from non-adopted (NA) comparison children in levels of the adrenal steroid hormone dehydroepiandrosterone (DHEA) and in its intra-individual covariation (coupling) with cortisol by adrenal pubertal stage. In an accelerated longitudinal design, 7- to 15-year-olds completed up to 3 annual assessments, which included nurse-conducted pubertal staging and the Modified Trier Social Stress Test for Children (TSST-M). Adrenal (pubic hair) rather than gonadal pubertal stage scores were used in the analysis. Paired salivary cortisol-DHEA samples were available at 60-80 min post-TSST-M. NA and PI children did not differ in DHEA levels, which were higher among children at more advanced pubertal stages (averaged across the sessions) for both groups. For NA children, post-stressor cortisol and DHEA were positively coupled across sessions at all average adrenal pubertal stages. For PI children who were, on average, at earlier adrenal pubertal stages, post-stressor cortisol and DHEA were not coupled, but PI children who were at later pubertal stages demonstrated positive cortisol-DHEA coupling similar to that of the NA children. We suggest that these findings provide insights into processes which may underlie pubertal recalibration of the HPA axis.
