Disentangling associations between pubertal development, healthy activity behaviors, and sex in adolescent social networks.

With the onset of puberty, youth begin to choose their social environments and develop health-promoting habits, making it a vital period to study social and biological factors contextually. An important question is how pubertal development and behaviors such as physical activity and sleep may be differentially linked with youths' friendships. Cross-sectional statistical network models that account for interpersonal dependence were used to estimate associations between three measures of pubertal development and youth friendships at two large US schools drawn from the National Longitudinal Study of Adolescent to Adult Health. Whole-network models suggest that friendships are more likely between youth with similar levels of pubertal development, physical activity, and sleep. Sex-stratified models suggest that girls' friendships are more likely given a similar age at menarche. Attention to similar pubertal timing within friendship groups may offer inclusive opportunities for tailored developmental puberty education in ways that reduce stigma and improve health behaviors.

Inequalities in emerging adult college students' sleep quality during the COVID-19 pandemic.

OBJECTIVE: To examine inequalities in sleep quality during the COVID-19 pandemic by gender, sexual orientation, race/ethnicity, and socioeconomic position (SEP), and test associations between discrimination and sleep quality in a national longitudinal cohort of emerging adult college students. PARTICIPANTS: Participants were enrolled in college full-time and were aged 18-22 at baseline. METHODS: Participants completed online surveys in spring 2020 (N = 707) and summer 2021 (n = 313). Measures included the Pittsburgh Sleep Quality Index (PSQI) and the Everyday Discrimination Scale. RESULTS: Most students reported poor sleep quality (78% in 2020; 82% in 2021) and those from marginalized groups generally experienced worse sleep quality. Discrimination was associated with poorer concurrent sleep quality at both time points. CONCLUSIONS: Sleep inequalities among college students continued to manifest during the pandemic, even when students were not necessarily on campus. Colleges should take a multi-pronged approach to promote sleep quality through individual, community, and institutional interventions.

Novel Assessment of the Impact of Irritability on Physiological and Psychological Frustration Responses in Adolescents.

OBJECTIVE: Irritability, typically defined as a proneness to anger, particularly in response to frustration, falls at the intersection of emotion and disruptive behavior. Despite well-defined translational models, there are few convergent findings regarding the pathophysiology of irritability. Most studies utilize computer-based tasks to examine neural responses to frustration, with little work examining stress-related responding to frustration in social contexts. The present study is the first to utilize the novel Frustration Social Stressor for Adolescents (FSS-A) to examine associations between adolescent irritability and psychological and physiological responses to frustration. METHOD: The FSS-A was completed by a predominantly male, racially, ethnically, and socioeconomically diverse sample of 64 12- to 17-year-olds, who were originally recruited as children with varying levels of irritability. Current irritability was assessed using the Multidimensional Assessment Profiles-Temper Loss scale (MAP-TL-Youth). Adolescents rated state anger and anxiety before and after the FSS-A, and usable salivary cortisol data were collected from 43 participants. RESULTS: Higher MAP-TL-Youth scores were associated with greater increases in anger during the FSS-A, but not increases in anxiety, or alterations in cortisol. Pre-task state anger negatively predicted the slope of the rise in cortisol observed in anticipation of the FSS-A. CONCLUSIONS: Results provide support for unique associations between adolescent irritability and anger during, and in anticipation of, frustrating social interactions. Such findings lay a foundation for future work aimed at informing physiological models and intervention targets.

Trajectories of sociopolitical stress during the 2020 United States presidential election season: Associations with psychological well-being, civic action, and social identities.

Sociopolitical stress arises in reaction to awareness of, exposure to, and/or involvement in political events. Among a longitudinal cohort of 628 college students from 10 universities across the U.S., we explored trajectories of sociopolitical stress during the 2020 United States presidential election season and examined relationships to psychological well-being. Growth mixture modeling classified our sample into four subgroups each with distinct trajectories of sociopolitical stress: High and Decreasing, Moderate and Increasing, Consistently Low, and High-to-Low. Participants with lower levels of sociopolitical stress expressed higher psychological well-being (high flourishing, high optimism, low anxiety symptoms, low depressive symptoms). The High and Decreasing subgroup was associated with the highest levels of civic action. Participants in the High and Decreasing trajectory were 20 times more likely to identify as LGBQ+, and 4 times more likely to be a woman or a transgender/gender diverse student, compared to participants in the Consistently Low subgroup.

Internalizing the COVID-19 pandemic: Gendered differences in youth mental health.

We review research on gendered patterns of internalizing behaviors in adolescents and emerging adults during the COVID-19 pandemic. We find that young women reported worse mental health than young men. Transgender and gender-diverse (TGD) youth are underrepresented in mental health research but often report the highest internalizing disorders of any gender group. Finally, we use intersectionality as a lens to acknowledge how gender and other social identities (e.g., race, socioeconomic position) impact mental health. Overall, this review points to gender as a meaningful social construct that is relevant for understanding young people's internalizing symptoms during the pandemic. We call attention to the structural factors underlying gender disparities and the need for intersectionality-informed approaches to work towards mental health equity.

Opportunities, challenges, and contextual supports to promote enacting maturing during adolescence.

Conceptions of adolescent "storm and stress" may be tied to a developmental mismatch that exists between young people's need for meaningful roles and autonomy - which we refer to as a need for enacting maturity - and the lack of such opportunities in most adolescents' contexts. First, we summarize our previous work on enacting maturity, including a review of the key components, links to wellbeing, and the nuances and limitations of this construct. Next, we extend this work by considering how the ecological contexts (e.g., family, school, community) young people are embedded in and their various intersecting social positions and identities (e.g., race/ethnicity, gender, immigrant origin) influence their experiences with enacting maturity. In this section, we pose several key questions for developmental scientists around: (a) identifying a young person's desire for, and phenomenological processing of, their adult-like roles, (b) understanding how complex and unequal responses to physical maturation shape opportunities for enacting maturity, and (c) attending to disparities in curricular and extracurricular pathways to leadership, responsibility, and autonomy. Finally, we discuss spaces with high potential to support enacting maturity, including both specially designed programs (e.g., youth participatory action research, leadership programs) as well as routine, everyday opportunities (e.g., interactions with teachers, training for companies that employ youth). We offer two levers for supporting enacting maturity across both types of spaces: adult allies and responsive organizations. Looking to exemplary programs, innovative leaders, social media, and case studies, we re-imagine how adults and organizations can promote young people enacting maturing in ways that are safe, worthwhile, and equitable.

Election-related sociopolitical stress and coping among college students in the United States.

Objective: The present study examines sociopolitical stress, coping, and well-being among college students. Participants: Young adult college students (N = 588; ages 18-29; 72% cisgender women) from 10 universities in the USA participated in this study. Methods: Participants completed a 45-minute online survey with closed-ended and open-ended questions, administered via Qualtrics. Results: Election-related sociopolitical stress was high with notable differences across students' demographic backgrounds (e.g., Hispanic/Latinx students, women, and sexual minority students reported high sociopolitical stress). Among those who reported being stressed by the election (N = 448), closed-ended and open-ended data reveal coping strategies including self-care, drugs and alcohol, and further civic action/political participation. Higher sociopolitical stress predicted more depression and many coping strategies were related with flourishing. Conclusions: Young adult college students are experiencing election-related sociopolitical stress and are coping in different ways. More work is needed to understand what coping strategies support well-being. Implications for colleges are discussed.

White adolescents' racial contexts: Associations with critical action.

This study takes a person-centered approach to investigate White youths' racial contexts by utilizing a latent profile analysis among a sample of White adolescents (N = 323, ages 16-17; 52% female, 48% male; data collected 1996-1998). Racial contexts were composed of parent, peer, and school influences, which revealed three distinct profiles: a Race Conscious profile, a Race Silent profile, and a Low Race Engagement profile. These profiles predicted White adolescents' critical action during emerging adulthood, where adolescents in the Race Conscious profile were engaged in more critical action as compared to the other two profiles. These findings suggest that the racial contexts in which White adolescents develop have direct implications on their desire to work toward, and take action for, social change.

Understanding patterns of heterogeneity in executive functioning during adolescence: Evidence from population-level data.

Executive functioning (EF) is fundamental to positive development. Yet, little is known about how to best characterize constellations of EF skills that may inform disparate associations between EF and behavior during adolescence. In the current study, cross-validated latent profile analysis (LPA) was used to derive profiles of EF based on measures of inhibitory control, working memory, and cognitive flexibility using data from 11,672 youth (52.2% male, mean age = 9.91 years) in the Adolescent Brain and Cognitive Development study. Four meaningful EF profiles emerged from the data representing Average EF, High EF, Low Inhibitory Control, and Low EF. Boys, youth from low-income households, and early developing youth were more likely to be in profiles distinguished by lower EF. Profile membership also predicted differences in externalizing, internalizing, and other problem behaviors assessed one year later. Findings indicate that youth may have distinct constellations of EF skills, underscoring the need for person-centered approaches that focus on patterns of individual characteristics.

Identifying diurnal cortisol profiles among young adults: Physiological signatures of mental health trajectories.

Previous research has used cortisol, the major hormonal byproduct of the hypothalamic pituitary adrenal (HPA) axis system, to explore how environmental stressors influence daily physiological functioning. Most of the research focused on diurnal cortisol has examined specific cortisol markers, with little consideration of how different components of the diurnal pattern may co-occur. Morning level, cortisol awakening response (CAR), bedtime level, as well as the diurnal slope and total cortisol exposure throughout the day (area under the curve; AUC), are five common parameters of diurnal HPA axis functioning that have been individually linked to physical and mental health outcomes, with mixed results. The current study introduces a novel approach to capture heterogeneity in HPA axis activity by using latent profile analysis to generate empirically-derived, theoretically supported diurnal cortisol profiles based on all five indicators. We analyzed salivary cortisol data from 278 young adults during a time of heightened sociopolitical stress - the 2016 U.S. presidential election - and examined whether profiles differentially predicted mental health trajectories across six months. Findings suggest that a specific combination of cortisol parameters (i.e., flat slope, high AUC, and high CAR) may predict worse mental health risk over time. Overall, this work suggests that diurnal cortisol profiles likely reflect distinct physiological underpinnings with unique health consequences that may not be observed by studying individual cortisol parameters.

Can White Guilt Motivate Action? The Role of Civic Beliefs.

Limited research has investigated factors that shape White youth's civic action aimed at social change. Investigating the relation between Whiteness and civic action is an essential step toward identifying and cultivating environments that encourage White youth to use their racial privilege to combat inequality through civic engagement. To address this gap in the literature, across two distinct samples, this study investigates the role of White guilt in motivating civic action and the moderating role of civic beliefs. Participants included all young adults who self-identified as White from two online survey studies (Study 1, N = 219 college students, 71.9% Women, 28.1% Men, mean age = 19.6; Study 2, N = 185, 50% current college students, 54.6% Women, 45.4% Men, mean age = 23.9). In Study 1, White guilt related to more civic action. In the context of high social responsibility, White guilt related to more civic action; in the context of low social responsibility, White guilt corresponded with less civic action. In Study 2, White guilt also related to more civic action, and civic efficacy emerged as a potential moderator. Collectively, these results highlight the potential for White guilt to be turned into meaningful civic action, particularly when coupled with civic beliefs.

"Constant Stress Has Become the New Normal": Stress and Anxiety Inequalities Among U.S. College Students in the Time of COVID-19.

PURPOSE: The purpose of this study is to document young adults' perceived stress and anxiety in a diverse sample of college students across the U.S. during the COVID-19 pandemic. METHODS: We recruited, via Instagram, a sample of full-time college students aged 18-22 from across the U.S. We surveyed them in April (baseline; N = 707; mean age = 20.0, SD = 1.3) and July (follow-up) 2020. This study presents overall levels of perceived stress and general anxiety symptoms and inequalities across each of these outcomes by gender, sexual orientation, race/ethnicity, and household income. We also explore potential explanations for these health issues by analyzing baseline qualitative data. RESULTS: All students, on average, were suffering from perceived stress and anxiety, with especially high levels in April. We also identified inequalities in college student mental well-being, particularly by gender identity and sexual orientation. Women reported worse well-being compared with men; transgender and gender diverse and sexual minority youths reported worse outcomes than their cisgender, heterosexual peers at both time points. Qualitative data illustrate how the COVID-19 pandemic has generated educational, economic, and environmental stressors that are affecting college students' well-being. CONCLUSIONS: As colleges and universities think about how to manage and mitigate the infectious disease dimensions of COVID-19 among their student populations, they must also consider who is most at risk for increased stress and anxiety during the pandemic.

The interaction between pubertal timing and childhood maltreatment on the risk of human papillomavirus infection among adolescent girls and young women.

PURPOSE: The goal of this study was to evaluate the effect of pubertal timing, and its interaction with prior childhood maltreatment, on the risk of cervical human papillomavirus (HPV) among sexually active adolescent minority female adolescents and young adults. METHODS: This cross-sectional study includes 842 adolescent girls and young women (aged 12 to 20 years; predominately Black and Hispanic) enrolled in an HPV vaccine surveillance study at a large adolescent health clinic in New York City between 2007 and 2016. Pubertal timing was assessed by self-reported age at menarche at baseline, with "early" and "late" defined as one standard deviation below (<11 years) or above (>13 years) the mean. Childhood exposure to abuse (sexual, physical and emotional) and neglect (physical and emotional) was assessed using the Childhood Trauma Questionnaire. Over 40 types of HPV infection were detected using the polymerase chain reaction in cervical Pap specimens. RESULTS: Results from multivariable logistic regression showed that early and late pubertal timing were marginally associated with a higher risk of HPV infection, adjusting for demographic and health covariates. Childhood maltreatment moderated the association between early pubertal timing and HPV infection: early pubertal timing was associated with a higher risk for HPV infection among maltreated girls (OR = 3.32, 95%CI:1.61-6.85), but not among non-maltreated girls (OR = 0.96, 95%CI:0.61-1.50; p-interaction<0.01). CONCLUSIONS: Variation in the timing of puberty and history of childhood maltreatment may have implications for adolescent sexual and reproductive health. Findings suggest that clinicians need to assess the biological and psychosocial risks in caring for youth.

Context Matters: Adolescent Neighborhood and School Influences on Young Adult Body Mass Index.

PURPOSE: Both schools and neighborhoods play important roles in determining adolescent weight status, but little is known about their relative importance, particularly in predicting long-term weight outcomes. We assessed the impacts of both school and neighborhood socioeconomic composition, social connectedness, and built environment during adolescence on weight status in young adulthood. METHODS: The study sample consisted of 14,625 respondents from Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health. Data were analyzed using cross-classified multilevel modeling to examine the joint effect of adolescents' school and neighborhood predictors on body mass index (BMI) 13 years later. RESULTS: Living in a neighborhood with lower average parent education during adolescence, and attending a school with lower average parent education, were each associated with higher BMI in young adulthood. Living in a neighborhood with more physical activity resources predicted lower young adult BMI, independent of adolescent weight, parent obesity status, and demographic characteristics. School physical activity resources and perceptions of social connectedness (in the school or neighborhood) were not significantly associated with young adult BMI. CONCLUSIONS: These findings highlight the importance of school and neighborhood socioeconomic composition during adolescence on young adult weight status. Results also suggest that improving neighborhood infrastructure may promote healthy weight.

Adolescent Sleep Barriers: Profiles within a Diverse Sample of Urban Youth.

Most adolescents face numerous obstacles to good sleep, which may undermine healthy development. In this study, we used latent class analysis and identified four categories of sleep barriers in a diverse sample of 553 urban youth (57% female). The majority profile, School/Screens Barriers, reported the most homework and extracurricular barriers, along with high screen time. The Home/Screens Barriers class (i.e., high environmental noise, light, screen use) and the High/Social Barriers class (i.e., high barriers across domains, particularly social) reported the poorest sleep quality and highest depressive/anxiety symptoms. The Minimal Barriers class-predominately male, with low depressive/anxiety symptoms-reported more sleep per night. We discuss implications of our findings for targeting interventions to address poor adolescent sleep among specific clusters of students.

Girls' Sleep Trajectories Across the Pubertal Transition: Emerging Racial/Ethnic Differences.

PURPOSE: This study aims to examine the longitudinal association between puberty and sleep in a diverse sample of girls and explore racial/ethnic differences in this association. METHODS: Using latent growth curve modeling, the present study measured pubertal development (timing and rate) and sleep (wake time and bedtime) in 1,239 socioeconomically and ethnically diverse girls starting when they were 6-8 years old and followed longitudinally for up to 8 years. Pubertal assessment was conducted annually in clinic by physical examination, classified by sexual maturation stage for breast and pubic hair development by trained raters. RESULTS: In line with previous research, black girls had the earliest pubertal development, followed by Hispanic, white, and Asian girls. Black girls, on average, reported significantly shorter sleep duration than Hispanic (ß = -.20, p < .001), Asian (ß = -.29, p = .002), and white (ß = -.35, p < .001) girls. In a series of dual-process models, we found that early pubertal timing predicted shorter sleep duration for early-maturing black girls (breast development: ß = .13, p = .005; pubic hair development: ß = .14, p = .012). There was no evidence of any association between pubertal rate and sleep. All models controlled for family socioeconomic status and body mass index. CONCLUSION: Sleep is essential for many aspects of youth development, including emotional, cognitive, and physical functioning. Developmental changes associated with puberty may put some early maturing girls at risk of shorter sleep duration in adolescence and exacerbate racial/ethnic disparities in health and well-being.

The long arm of childhood: Preschool associations with adolescent health.

The current study examines the extent to which participation in preschool at age 4 is associated with blood pressure, body mass index, and awakening cortisol at age 15. We capitalize on data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development to examine differences in adolescent health among children who attended preschool, parental care, or home-based care at age 4 (n = 742). Using quasi-experimental methods, we found that preschool participation was associated with multiple positive health outcomes in adolescence. In particular, preschool participation was associated with lower systolic and diastolic blood pressure and lower arterial pressure during adolescence compared with children in parental care (but not home-based care). Preschool participation was also related to lower levels of cortisol (measured at waking) compared with youth who did not attend preschool. More hours in preschool was associated with higher body mass index and more teacher education is associated with lower teacher education. Results are discussed in terms of how early preschool experiences may help to explain long-term health trajectories. (PsycINFO Database Record

Balancing scientific accuracy and participant burden: testing the impact of sampling intensity on diurnal cortisol indices.

Despite the increasing popularity of incorporating salivary cortisol measurement into health and social science research, relatively little empirical work has been conducted on the number of saliva samples across the day required to capture key features of the diurnal cortisol rhythm, such as the diurnal cortisol slope, the area under the curve (AUC), and the cortisol awakening response (CAR). The primary purpose of this study is to compare slope, AUC, and CAR measures obtained from an intensive sampling protocol with estimates from less intensive protocols, to identify sampling protocols with minimal participant burden that still provide reasonably accurate assessment of each of these measures. Twenty-four healthy adults provided samples four times in the first hour awake, and then every hour throughout the rest of the day until bedtime (M = 17.8 samples/day; SD = 2.0), over two consecutive days (N = 862 total samples). We compared measures calculated from this maximum intensity protocol to measures calculated from two to six sampling points per day. Overall, results show that salivary cortisol protocols with two fixed samples (waking and bedtime) and three additional daily samples, closely approximates the full cortisol decline (slope). Abbreviated sampling protocols of total cortisol exposure across the day (AUC), however, were not well approximated by reduced sampling protocols. CAR measures based on only two samples, including waking cortisol and a second sample measured at a fixed time point between 30 and 60 min after waking, provided a measure of the CAR that closely approximated CAR measures obtained from 3 or 4 sampling points.

Puberty and perimenopause: reproductive transitions and their implications for women's health.

This scoping review synthesizes existing research on two major transitions in females' lives: puberty and perimenopause. These two periods of vast physiological change demarcate the beginning and the end of the reproductive life cycle and are associated with major neuroendocrine reorganization across two key systems, the hypothalamic-pituitary-gonadal (HPG) axis the hypothalamus-pituitary-adrenal (HPA) axis. Despite growing evidence suggesting that the timing and experience of puberty and perimenopause are related to various physical and mental health outcomes (e.g., mood disorders, metabolism, cardiovascular health, autoimmune conditions, and cancer), these two processes are rarely examined together. In this paper, we bridge these disparate literatures to highlight similarities, isolate inconsistencies, and identify important areas for future research in women's health.

Quality of relationships with parents and friends in adolescence predicts metabolic risk in young adulthood.

OBJECTIVE: This study was designed to examine whether family and peer relationships in adolescence predict the emergence of metabolic risk factors in young adulthood. METHOD: Participants from a large, nationally representative cohort study (N = 11,617 for these analyses) reported on their relationship experiences with parents and close friends during adolescence. Fourteen years later, interviewers collected blood samples, as well as anthropometric and blood pressure measurements. Blood samples were analyzed for HbA1c. RESULTS: Ordered logistic regressions revealed that for females, supportive parent-child relationships and close male friendships in adolescence were associated with reduced odds of having elevated metabolic risk markers in young adulthood. These effects remained significant even after controlling for baseline measures of body mass index (BMI) and health and demographic covariates. The protective effects of close relationships were not significant for males, however. Exploratory analyses with 2-parent families revealed that supportive father-child relationships were especially protective for females. CONCLUSIONS: These findings suggest that, for females, close and supportive relationships with parents and male friends in adolescence may reduce the risk of metabolic dysregulation in adulthood.
