Puberty and Girls' Delinquency: A Test of Competing Models Explaining the Relationship between Pubertal Development and Delinquent Behavior

Early puberty: a review on its role as a risk factor for metabolic and mental disorders

Accumulating evidence indicates that there is a trend of early puberty onset in humans. The early timing of puberty has raised concerns due to its association with significant negative health outcomes. However, overall impact and potential risk of early puberty remain uncertain. In this study, we conducted a comprehensive review of existing epidemiological studies to gain insights into the long-term adverse health effects associated with early puberty. Our objective was to provide a consolidated summary of these outcomes at a population level by considering studies that encompass various indicators of puberty. In all, early puberty has been identified as a potential risk factor for various metabolic diseases, such as obesity, diabetes, cardiovascular diseases (CVD). Children who experience early puberty are more likely to have a higher body mass index (BMI) during adulthood, increasing their risk of obesity. Early puberty also has been found to be an independent risk factor for diabetes mellitus, including gestational diabetes mellitus (GDM) and type 2 diabetes mellitus (T2DM), as earlier onset of menarche in girls and voice breaking in boys is associated with a higher prevalence of T2DM. Furthermore, evidence suggests that early puberty may contribute to an elevated risk of CVD, including conditions like coronary heart disease (CHD), stroke, angina, and hypertension. In addition, adolescents who experience early puberty, particularly girls, are more likely to suffer from mental problems, such as behavioral dysfunction and depression. Notably, early puberty has a more significant impact on girls than boys. Further research should consider the underlying mechanisms and potential preventive measures.

Latent heterogeneity of deviant behaviors and associated factors among ethnic minority adolescents: a latent class analysis

BACKGROUND

Deviant behaviors are common during adolescence. Despite the diversity of juvenile delinquency, the patterns of deviant behaviors remain unclear in ethnic minorities. The present study aimed to evaluate the latent heterogeneity of deviant behaviors and associated factors in ethnic minority Yi adolescents.

METHODS

The present study recruited a large sample of 1931 ethnic minority Yi adolescents (53.4% females, mean age = 14.7 years, SD 1.10) in five secondary schools in 2022 in Sichuan, China. The participants completed measures on 13 deviant behaviors and demographic characteristics, attitudinal self-control, and psychological distress. Sample heterogeneity of deviant behaviors was analyzed via latent class analysis using class as the cluster variable.

RESULTS

The data supported three latent classes with measurement invariance by sex. 68.2%, 28.0%, and 3.8% of the sample were in the Normative, Borderline, and Deviant class, with minimal, occasional, and extensive deviant behaviors, respectively. The Deviant class was more prevalent in males (6.5%) than females (1.6%). There were significant class differences in domestic violence, school belonging, self-control, anxiety, and depressive symptoms. Males, domestic violence, low school belonging, and impaired self-control significantly predicted higher odds of the Deviant and Borderline classes compared to the normative class.

CONCLUSION

This study provided the first results on three latent classes of deviant behaviors with distinct profiles in ethnic minority adolescents in rural China. These results have practical implications to formulate targeted interventions to improve the psycho-behavioral functioning of the at-risk adolescents in ethnic minorities.

The Influence of Pubertal Development on Early Adolescent Sleep and Changes in Family Functioning

Pubertal development has been separately linked to adolescents' sleep problems and larger family functioning, but research connecting these inter-related processes remains sparse. This study aimed to examine how pubertal status and tempo were related to early adolescents' sleep and their family functioning. Using longitudinal data from the Adolescent Brain and Cognitive Development study, the study's sample (N = 4682) was 49.2% female, was an average of 9.94 years old at baseline, and was 60.1% white. Analyses in the current study modeled the indirect associations between pubertal change and changes in family conflict via adolescent sleep duration and variability of duration. The results suggested that pubertal status and tempo predicted shorter adolescent sleep durations and greater variability in those durations, which predicted residual increases in family conflict. The findings highlight the role of adolescents' pubertal changes in their sleep and how such changes can negatively affect family functioning.

Endocrine Health and Health Care Disparities in the Pediatric and Sexual and Gender Minority Populations: An Endocrine Society Scientific Statement

Endocrine care of pediatric and adult patients continues to be plagued by health and health care disparities that are perpetuated by the basic structures of our health systems and research modalities, as well as policies that impact access to care and social determinants of health. This scientific statement expands the Society's 2012 statement by focusing on endocrine disease disparities in the pediatric population and sexual and gender minority populations. These include pediatric and adult lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) persons. The writing group focused on highly prevalent conditions-growth disorders, puberty, metabolic bone disease, type 1 (T1D) and type 2 (T2D) diabetes mellitus, prediabetes, and obesity. Several important findings emerged. Compared with females and non-White children, non-Hispanic White males are more likely to come to medical attention for short stature. Racially and ethnically diverse populations and males are underrepresented in studies of pubertal development and attainment of peak bone mass, with current norms based on European populations. Like adults, racial and ethnic minority youth suffer a higher burden of disease from obesity, T1D and T2D, and have less access to diabetes treatment technologies and bariatric surgery. LGBTQIA youth and adults also face discrimination and multiple barriers to endocrine care due to pathologizing sexual orientation and gender identity, lack of culturally competent care providers, and policies. Multilevel interventions to address these disparities are required. Inclusion of racial, ethnic, and LGBTQIA populations in longitudinal life course studies is needed to assess growth, puberty, and attainment of peak bone mass. Growth and development charts may need to be adapted to non-European populations. In addition, extension of these studies will be required to understand the clinical and physiologic consequences of interventions to address abnormal development in these populations. Health policies should be recrafted to remove barriers in care for children with obesity and/or diabetes and for LGBTQIA children and adults to facilitate comprehensive access to care, therapeutics, and technological advances. Public health interventions encompassing collection of accurate demographic and social needs data, including the intersection of social determinants of health with health outcomes, and enactment of population health level interventions will be essential tools.

The Distinct Roles of Biological and Perceived Pubertal Timing in Delinquency and Depressive Symptoms from Adolescence to Adulthood

Pubertal timing is a robust predictor of externalizing and internalizing problems in adolescence, but controversies remain whether only early or off-time (both early and late) pubertal timing is associated with negative developmental outcomes and whether effects differ across perceptions of pubertal timing and actual biological pubertal timing. Additionally, less is known about the longevity of pubertal timing effects and mediators of effects that persist through adolescence and into adulthood. This longitudinal study investigated the effects of early and off-time pubertal timing, in form of perceived pubertal timing relative to peers and reported biological pubertal timing relative to age, on delinquency and depressive symptoms in adolescence and young adulthood between 2003 and 2022. Peer deviance and school connectedness were examined as mediators of any persisting effects. The sample included 704 youth (52% male, 76% African American, 22% Non-Hispanic White) who were assessed at four time points from early adolescence (Mean ages: 11.8, 13.2) to late adolescence (Mean age: 17.6) and young adulthood (Mean age: 27.7). Perceived off-time pubertal timing in males and early biological pubertal timing in both males and females were risk factors for persistent delinquency into young adulthood, but neither form of pubertal timing was associated with depressive symptoms. None of the effects were mediated by peer deviance or school connectedness. These findings advance the understanding of more nuanced effects of pubertal timing on adjustment problems in diverse youth as they develop from early adolescence to adulthood.

Early pubertal maturation and externalizing behaviors: Examination of peer delinquency as mediator and cognitive flexibility as a moderator

INTRODUCTION

While peer delinquency is a known mediator between early pubertal timing and externalizing behaviors, little is known about factors that could protect against the adverse influence of peer delinquency. This study assesses the possible moderating role of cognitive flexibility, which is one index of executive functioning that facilitates flexible and adaptive responses to challenging situations. We assessed the interactive influence of peer delinquency and cognitive flexibility in the association between pubertal maturation and externalizing behaviors in boys and girls.

METHOD

Participants were 220 adolescents (111 boys) from the United States, between the ages of 11 and 16 years (M = 13.2, SD = 1.53) who participated in the Adolescent Emotion Study (AES).

RESULTS

Findings from the cross-sectional path modeling analyses provided evidence for the mediating role of peer delinquency for boys and girls, indicating that early maturing adolescents tend to affiliate with delinquent peers, which in turn exacerbates externalizing problems. Additionally, the moderating role of cognitive flexibility was also demonstrated for both boys and girls. Region of significance tests revealed that relatively well-developed cognitive flexibility skills could protect against the adverse influences of peer delinquency, whereas lower levels could exacerbate those negative influences.

CONCLUSION

These findings suggest that involvement with deviant peers increases vulnerability for both early maturing boys and girls. Additionally, cognitive flexibility was an important moderating factor for adolescents, such that youths with less developed skills would be at a higher risk for psychopathology, whereas those with better development could be protected.

Disentangling the Effects of Boys' Pubertal Timing: The Importance of Social Context

Some prior studies have found that, for boys, earlier puberty is linked to higher crime and delinquency, while other studies have found that earlier puberty is associated with greater social competence and beneficial psychosocial development. The current study suggests that these seemingly contradictory results actually represent two divergent pathways by which earlier pubertal timing can affect adjustment. Which pathway boys take is highly dependent on psychosocial context. Using a sample of 310 African American boys and their primary caregivers tracked across three waves of data collection from ages 10.55-18.84 from the Family and Community Health Study (FACHS), the current study utilizes Latent Moderated Structural Equation Modeling (LMS) to analyze effects of interactions between pubertal timing and social contextual factors on criminal behavior and social competence. Results suggest that criminogenic effects of early puberty are contingent on deviant peer group, poor school experience, harsh parenting, and neighborhood disorganization, whereas the association between earlier puberty and social competence is attenuated by harsh parenting. Results suggest that modeling both positive and negative development outcomes together may give a clearer picture of the developmental consequences of pubertal timing for boys. In addition, this study shows the importance of social context in shaping the meaning and consequences of biological variables like pubertal timing.
