ABSTRACT

Cross-sectional data allow the investigation of how genetics influence health at a single time point, but to understand how the genome impacts phenotype development, one must use repeated measures data. Ignoring the dependency inherent in repeated measures can exacerbate false positives and requires the utilization of methods other than general or generalized linear models. Many methods can accommodate longitudinal data, including the commonly used linear mixed model and generalized estimating equation, as well as the less popular fixed-effects model, cluster-robust standard error adjustment, and aggregate regression. We simulated longitudinal data and applied these five methods alongside naïve linear regression, which ignored the dependency and served as a baseline, to compare their power, false positive rate, estimation accuracy, and precision. The results showed that the naïve linear regression and fixed-effects models incurred high false positive rates when analyzing a predictor that is fixed over time, making them unviable for studying time-invariant genetic effects. The linear mixed models maintained low false positive rates and unbiased estimation. The generalized estimating equation was similar to the former in terms of power and estimation, but it had increased false positives when the sample size was low, as did cluster-robust standard error adjustment. Aggregate regression produced biased estimates when predictor effects varied over time. To show how the method choice affects downstream results, we performed longitudinal analyses in an adolescent cohort of African and European ancestry. We examined how developing post-traumatic stress symptoms were predicted by polygenic risk, traumatic events, exposure to sexual abuse, and income using four approaches-linear mixed models, generalized estimating equations, cluster-robust standard error adjustment, and aggregate regression. While the directions of effect were generally consistent, coefficient magnitudes and statistical significance differed across methods. Our in-depth comparison of longitudinal methods showed that linear mixed models and generalized estimating equations were applicable in most scenarios requiring longitudinal modeling, but no approach produced identical results even if fit to the same data. Since result discrepancies can result from methodological choices, it is crucial that researchers determine their model a priori, refrain from testing multiple approaches to obtain favorable results, and utilize as similar as possible methods when seeking to replicate results.

ABSTRACT

The body of scientific knowledge accumulated by the scholarly disciplines such as Developmental Psychopathology can achieve meaningful public impact if wielded and used in policy decision-making. Scientific study of how policymakers use research evidence underscores the need for researchers' policy engagement; however, barriers in the academy create conditions in which there is a need for infrastructure that increases the feasibility of researchers' partnership with policymakers. This need led to the development of the Research-to-Policy Collaboration model, a systematic approach for developing "boundary spanning" infrastructure, which has been experimentally tested and shown to improve policymakers' use of research evidence and bolster researchers' policy skills and engagement. This paper presents original research regarding the optimization of the RPC model, which sought to better serve and engage scholars across the globe. Trial findings shed light on ways to improve conditions that make good use of researchers' time for policy engagement via a virtual platform and enhanced e-communications. Future directions, implications, and practical guidelines for how scientists can engage in the political process and improve the impact of a collective discipline are also discussed.

ABSTRACT

Telomere length (TL) is an important biomarker of cellular aging, yet its links with health outcomes may be complicated by use of different tissues. We evaluated within- and between-individual variability in TL and quality metrics of DNA across five tissues using a cross-sectional dataset ranging from 8 to 70 years (N = 197). DNA was extracted from all tissue cells using the Gentra Puregene DNA Extraction Kit. Absolute TL (aTL) in kilobase pairs was measured in buccal epithelial cells, saliva, dried blood spots (DBS), buffy coat, and peripheral blood mononuclear cells (PBMCs) using qPCR. aTL significantly shortened with age for all tissues except saliva and buffy coat, although buffy coat was available for a restricted age range (8 to 15 years). aTL did not significantly differ across blood-based tissues (DBS, buffy coat, PBMC), which had significantly longer aTL than buccal cells and saliva. Additionally, aTL was significantly correlated for the majority of tissue pairs, with partial Spearman's correlations controlling for age and sex ranging from ⍴ = 0.18 to 0.51. We also measured quality metrics of DNA including integrity, purity, and quantity of extracted DNA from all tissues and explored whether controlling for DNA metrics improved predictions of aTL. We found significant tissue variation: DNA from blood-based tissues had high DNA integrity, more acceptable A260/280 and A260/230 values, and greater extracted DNA concentrations compared to buccal cells and saliva. Longer aTL was associated with lower DNA integrity, higher extracted DNA concentrations, and higher A260/230, particularly for saliva. Model comparisons suggested that incorporation of quality DNA metrics improves models of TL, although relevant metrics vary by tissue. These findings highlight the merits of using blood-based tissues and suggest that incorporation of quality DNA metrics as control variables in population-based studies can improve TL predictions, especially for more variable tissues like buccal and saliva.

ABSTRACT

Background: Evolving and emerging contexts require interventions to respond and adapt. The COVID-19 pandemic necessitated a quick adaptation from in-person to virtual delivery. Not only were there few programs able to transition to virtual delivery, there was a lack of parent-focused CSA-prevention programs. The current study describes the responsive adaptation of a parent-focused child sexual abuse (CSA) prevention module (Smart Parents-Safe and Healthy Kids; SPSHK) for virtual delivery. Design and methods: This two-phase study used mixed-methods to inform and pilot test adaptations to the virtual module. In Phase 1, parenting providers with and without experience delivering SPSHK (N = 110) completed anonymous surveys and a subsample (n = 27) subsequently participated in brief interviews elaborate on challenges and needed adaptations for virtual platforms. Results: Providers indicated the greatest technological difficulties with parents' access to technology noting the inability to use a screensharing function. Thus, providers recommended no adaptations for the virtual delivery of SPSHK. In Phase 2, the virtual SPSHK module was piloted with nine parents. Results demonstrated virtual SPSHK was acceptable and feasibly implemented. Pre-posttest assessments indicated increases in parents' CSA-related awareness and use of protective behaviors. Conclusion: The current study suggests the promise of virtual SPSHK implementation and may act as a blueprint for other parent-focused CSA-prevention programs, but also more general parenting programs, considering virtual delivery.

ABSTRACT

BACKGROUND: Young adults with a history of foster care have higher risk for substance use disorders. Social systems can deliver substance use prevention to youth; however, the timing of intervention delivery and how needs differ for youth in foster care are unclear. OBJECTIVE: To compare initiation and rates of substance use among adolescents in foster care to demographically similar adolescents never in foster care as identified by the healthcare system, and identify factors associated with increased substance use. PARTICIPANTS AND SETTING: Youth in foster care (n = 2787, ages 10-20, inclusive) and demographically matched youth never in foster care (n = 2787) were identified using linked child welfare and electronic health records from a single pediatric children's hospital and county over a five-year period (2012-2017). METHODS: All healthcare encounters were reviewed and coded for substance use by type (alcohol, tobacco, cannabis, other). Age of first reported or documented substance use was also captured. Demographic and child welfare information was extracted from administrative records. Survival and logistic regression models were estimated. RESULTS: In adjusted models, youth in foster care initiated substance use at earlier ages (HR = 2.50, p < .01) and had higher odds of engaging in use (AOR = 1.54; p < .01) than youth never in care. By age 12, substance use initiation was more likely while youth were in foster care than when they were not in foster care (HR = 1.42, p < .01). Placement stability and family care settings reduced odds of lifetime substance use. CONCLUSIONS: Foster care placement is associated with substance use. Screening may be important for prevention.

ABSTRACT

Since the 1980s, school-based child sexual abuse (CSA) prevention programs have been the prevailing prevention strategy in the United States. Despite demonstrated effectiveness, there is a lack of infrastructure and educational policy ensuring all students receive these programs. A pragmatic application of the RE-AIM implementation framework, this study provides an overview of a multi-county implementation effort of the school-based CSA prevention program, Safe Touches. Implementation efforts across five counties in a Mid-Atlantic state are described at three levels: organizational (school districts), child, and program facilitator. Children's CSA-related knowledge was measured at four time points: pre-workshop, immediately post-workshop, and then 6 and 12 months post-workshop. Facilitators completed an anonymous survey post-implementation. Over the course of one and a half academic years, Safe Touches was implemented in 718 public school districts, reaching in total 14,235 second-grade students. Students' significantly increased knowledge from pre- to post-workshop and gains were maintained at 6 and 12 months (ps <.001). A total of 29 disclosures of maltreatment were made by students to facilitators during or after the workshop. Facilitators generally adopted Safe Touches and attested to the feasibility and benefits of its large-scale implementation as well as the negligible negative impacts for children. When implemented systematically, school-based CSA prevention is able to reach a high number of students, effectively increase CSA-related knowledge, and facilitates disclosures. To maximize the potential public health impact, it is suggested that state funds be allocated to support the implementation of such programs as part of standard education costs.

ABSTRACT

School-based child sexual abuse (CSA) programs effectively increase students' CSA-related knowledge. This study focuses on an implementation trial of Safe Touches, an empirically supported, school-based CSA prevention program, that was disrupted by the COVID-19 pandemic. We sought to demonstrate gains in CSA-related knowledge following Safe Touches but were limited to a pre-post design. A total of 2,210 students across five counties in a Mid-Atlantic state received the Safe Touches workshop between September 2019 and March 2020. McNemar's chi-square test was used to assess changes in the proportion of correct responses pre-workshop (Time 1) and one-week post-workshop (Time 2). Students' CSA-related knowledge increased significantly based on changes in mean CSA knowledge scores and the number of correct item-level responses assessed at Time 1 and Time 2 (p < .000). Leveraging the experience of the facilitators' who delivered these workshops prior to the disruption of implementation, we gathered facilitators' perspectives to explore the viability of offering Safe Touches virtually. In July 2020, 16 facilitators completed an electronic survey designed to understand the viability of a virtual Safe Touches workshop. Three themes emerged from facilitator feedback on virtual programming: student engagement concerns, handling disclosures, and technology access to a virtual program. The findings of this study indicate that the Safe Touches workshop significantly increased CSA-related knowledge and, overall, facilitators supported further exploration and development of a virtual Safe Touches workshop. The transition of empirically supported school-based CSA prevention programs to a virtual delivery modality is necessary to maintain an effective means of primary prevention and opportunity for disclosure.

ABSTRACT

Background: Early life adversity and psychiatric disorders are associated with earlier declines in neurocognitive abilities during adulthood. These declines may be preceded by changes in biological aging, specifically epigenetic age acceleration, providing an opportunity to uncover genome-wide biomarkers that identify individuals most likely to benefit from early screening and prevention. Methods: Five unique epigenetic age acceleration clocks derived from peripheral blood were examined in relation to latent variables of general and speeded cognitive abilities across two independent cohorts: 1) the Female Growth and Development Study (FGDS; n = 86), a 30-year prospective cohort study of substantiated child sexual abuse and non-abused controls, and 2) the Biological Classification of Mental Disorders study (BeCOME; n = 313), an adult community cohort established based on psychiatric disorders. Results: A faster pace of biological aging (DunedinPoAm) was associated with lower general cognitive abilities in both cohorts and slower speeded abilities in the BeCOME cohort. Acceleration in the Horvath clock was significantly associated with slower speeded abilities in the BeCOME cohort but not the FGDS. Acceleration in the Hannum clock and the GrimAge clock were not significantly associated with either cognitive ability. Accelerated PhenoAge was associated with slower speeded abilities in the FGDS but not the BeCOME cohort. Conclusions: The present results suggest that epigenetic age acceleration has the potential to serve as a biomarker for neurocognitive decline in adults with a history of early life adversity or psychiatric disorders. Estimates of epigenetic aging may identify adults at risk of cognitive decline that could benefit from early neurocognitive screening.

ABSTRACT

Life course epidemiology seeks to understand the intricate relationships between risk factors and health outcomes across different stages of life to inform prevention and intervention strategies to optimize health throughout the lifespan. However, extant evidence has predominantly been based on separate analyses of data from individual birth cohorts or panel studies, which may not be sufficient to unravel the complex interplay of risk and health across different contexts. We highlight the importance of a multi-study perspective that enables researchers to: (a) Compare and contrast findings from different contexts and populations, which can help identify generalizable patterns and context-specific factors; (b) Examine the robustness of associations and the potential for effect modification by factors such as age, sex, and socioeconomic status; and (c) Improve statistical power and precision by pooling data from multiple studies, thereby allowing for the investigation of rare exposures and outcomes. This integrative framework combines the advantages of multi-study data with a life course perspective to guide research in understanding life course risk and resilience on adult health outcomes by: (a) Encouraging the use of harmonized measures across studies to facilitate comparisons and synthesis of findings; (b) Promoting the adoption of advanced analytical techniques that can accommodate the complexities of multi-study, longitudinal data; and (c) Fostering collaboration between researchers, data repositories, and funding agencies to support the integration of longitudinal data from diverse sources. An integrative approach can help inform the development of individualized risk scores and personalized interventions to promote health and well-being at various life stages.

ABSTRACT

Child sexual abuse (CSA) is a public health problem of considerable magnitude. The prevailing primary prevention strategies are universal, school-based CSA prevention programs, some of which have been designated as evidence-based, such as Safe Touches. However, to reach their public health impact potential, effective universal school-based CSA prevention programs require effective and efficient dissemination and implementation strategies. The purpose of this study was to demonstrate the reach and effectiveness of a school-based CSA prevention curriculum, Safe Touches, when implemented on a wide scale. Using a longitudinal cohort design, children in second grade classrooms in public elementary schools in five counties received the Safe Touches workshop and completed surveys designed to assess gains in knowledge at four timepoints (one week prior, immediately post-workshop, 6- and 12-months post-workshop). In total, the Safe Touches workshop was delivered in 718 classrooms in 92% of school districts, reaching ~14,235 second graders. Multilevel models (n = 3,673) revealed that Safe Touches significantly increased CSA-related knowledge, and that these gains were maintained 12-months post-workshop (ps < .001). There were some small but significant time-varying effects among participants in schools with a greater percentage of low income and minority students, but these effects largely disappeared 12-months post workshop. This study demonstrates that a single-session, universal school-based CSA prevention program can effectively increase children's knowledge when implemented and disseminated on a wide scale and knowledge gains can be retained 12-months post intervention.

ABSTRACT

BACKGROUND: Immune cell proportions can be used to detect pathophysiological states and are also critical covariates in genomic analyses. The complete blood count (CBC) is the most common method of immune cell proportion estimation, but immune cell proportions can also be estimated using whole-genome DNA methylation (DNAm). Although the concordance of CBC and DNAm estimations has been validated in various adult and clinical populations, less is known about the concordance of existing estimators among stress-exposed individuals. As early life adversity and acute psychosocial stress have both been associated with unique DNAm alterations, the concordance of CBC and DNAm immune cell proportion needs to be validated in various states of stress. RESULTS: We report the correlation and concordance between CBC and DNAm estimates of immune cell proportions using the Illumina EPIC DNAm array within two unique studies: Study 1, a high-risk pediatric cohort of children oversampled for exposure to maltreatment (N = 365, age 8 to 14 years), and Study 2, a sample of young adults who have participated in an acute laboratory stressor with four pre- and post-stress measurements (N = 28, number of observations = 100). Comparing CBC and DNAm proportions across both studies, estimates of neutrophils (r = 0.948, p < 0.001), lymphocytes (r = 0.916, p < 0.001), and eosinophils (r = 0.933, p < 0.001) were highly correlated, while monocyte estimates were moderately correlated (r = 0.766, p < 0.001) and basophil estimates were weakly correlated (r = 0.189, p < 0.001). In Study 1, we observed significant deviations in raw values between the two approaches for some immune cell subtypes; however, the observed differences were not significantly predicted by exposure to child maltreatment. In Study 2, while significant changes in immune cell proportions were observed in response to acute psychosocial stress for both CBC and DNAm estimates, the observed changes were similar for both approaches. CONCLUSIONS: Although significant differences in immune cell proportion estimates between CBC and DNAm exist, as well as stress-induced changes in immune cell proportions, neither child maltreatment nor acute psychosocial stress alters the concordance of CBC and DNAm estimation methods. These results suggest that the agreement between CBC and DNAm estimators of immune cell proportions is robust to exposure to child maltreatment and acute psychosocial stress.

ABSTRACT

This study used longitudinal data to elucidate how trajectories of negative parenting across adolescence are associated with young adult health risk behaviors (HRBs) by testing difficulties with emotion regulation and externalizing symptomatology as sequential underlying mediators. The sample included 167 adolescents (53% males, Mage  = 14 at Time 1 and Mage  = 18 at Time 5) who were assessed five times. Adolescents self-reported on negative parenting, emotion regulation, externalizing symptomatology, and engagement in HRBs. Results suggest that increasingly negative parenting across adolescence has adverse consequences for emotion regulation development and in turn, externalizing symptomatology, which confers risk for young adult HRBs. Results offer insights towards mechanisms for prevention and intervention and public health policy aimed at reducing the prevalence and consequences of engagement in HRBs.

ABSTRACT

Child maltreatment (CM) is a robust risk factor for adolescent depressive and post-traumatic stress disorder (PTSD) symptoms. Quality attachment relationships have been posited as a protective factor but findings are equivocal and studies have not adequately considered the complex network of interpersonal relationships that adolescents rely on. The current study applied a person-centered approach to (a) identify subgroups of adolescent females characterized by distinct patterns of attachment quality with peers, fathers, and mothers and (b) determine if the effect of maltreatment on depressive and PTSD symptoms varied as a function of distinct patterns of attachment quality. Data came from a prospective, longitudinal cohort study of 464 racially diverse and adolescent females designed to examine the developmental sequelae of substantiated CM (260 maltreated and 204 demographically matched, nonmaltreated comparisons). Latent profile analysis (LPA) revealed four profiles of attachment characterized by: (a) above-average attachment quality across all three relationships (N = 207, 44.6%); (b) below-average quality with father and friends and above-average quality with mothers (N = 128, 27.6%); (c) below-average quality across all three relationships (N = 106, 22.9%); and (d) very low-(-1 SD) quality with mothers and above-average quality with fathers and friends (N = 23, 5.0%). Moderation models revealed that cumulative maltreatment exposure resulted in greater adolescent depressive symptoms only for those with a profile of attachment consisting of very low-quality maternal attachment and high-quality father and friend attachments. Profiles did not significantly moderate the effect of maltreatment on PTSD symptoms. Results identify subgroups of maltreatment survivors most vulnerable to the development of depression in adolescence. Such groups should be targets for the provision of finite clinical resources with clinical interventions that seek to promote healthy maternal attachment relationships to mitigate the impact of maltreatment on depression.

ABSTRACT

BACKGROUND: As constant figures in children's lives, parents are key in protecting children from sexual abuse. One barrier to reaching parents is that the topic can be difficult to broach and is sensitive in nature. Such barriers can interfere with implementation and fidelity of evidence-based prevention strategies that are focused on reducing rates of childhood sexual abuse (CSA). AIMS: In this exploratory study, we examine provider attitudes about delivering CSA-specific content in an evidence-based prevention module and their self-efficacy. METHOD: Thirty-three providers participated in three surveys: prior to a skills-oriented training on how to deliver the CSA prevention module (pretraining), immediately posttraining, and 6 months posttraining. Changes in self-reported willingness to deliver content, beliefs about parents' role in CSA prevention, and confidence about their ability to deliver content were assessed over time. Open-ended questions were coded thematically to reinforce quantitative findings. RESULTS: Prior to training, providers were worried that parents would respond negatively to CSA content and were concerned about their comfort level discussing victimization and sexual development. Findings suggest that skill-oriented training and provision scripts effectively supported providers and improved confidence in delivering CSA prevention content. DISCUSSION: Provider self-efficacy is an important element of implementation fidelity. This exploratory study demonstrated that, though providers may approach CSA content with wariness and trepidation, adequate skills-oriented training can reduce negative attitudes and increase perceived efficacy in the actual delivery of CSA content that persists through implementation. CONCLUSION: Skills-based training can significantly enhance fidelity in the delivery of difficult content included in parent-focused preventative interventions.

ABSTRACT

Flexible self-regulation has been shown to be an adaptive ability. This study adapted and validated the adult Flexible Regulation of Emotional Expression (FREE) Scale for use with youth (FREE-Y) in community and maltreatment samples. The FREE-Y measures the ability to flexibly enhance and suppress emotion expression across an array of hypothetical social scenarios. Participants (N = 654, 8-19 years) were included from three studies. Confirmatory factor analysis (CFA) confirmed a theoretically appropriate higher order factor structure. Using multiple-group CFAs, measurement invariance was achieved across maltreatment status, age, and gender. Reliabilities were adequate and construct validity was demonstrated through associations with measures of emotion regulation, psychopathology, IQ, and executive functioning. Group comparisons indicated lower Suppression and Flexibility scores for maltreated versus comparison participants. Findings suggest that the FREE-Y is a valid measure of expressive regulation ability in youth that can be applied across a range of populations.

ABSTRACT

Adolescent pregnancy (AP) is a significant public health issue. Child maltreatment (CM) represents an established risk factor, yet little is known about the explanatory mechanisms linking the phenomena. Informed by developmental theory, this study prospectively tested seven multi-level, indirect pathways that could plausibly explain the relationship between CM and AP: (1) substance use (polysubstance use and frequency); (2) sexual risk behavior; (3) depressive symptoms; (4) posttraumatic stress disorder symptoms; (5) cognitive dysregulation; (6) pregnancy desire and difficulty expectancies; and (7) age at menarche. Data came from a prospective, longitudinal cohort study of 469 ethnically diverse, nulliparous adolescent females, designed to examine the impact of substantiated CM on reproductive outcomes such as pregnancy and childbirth (265 maltreated and 204 demographically matched comparison adolescents). A multiple-mediator structural equation model was conducted to simultaneously test multiple indirect effects while accounting for confounding variables. Maltreatment had an indirect effect on pregnancy via substance use and higher pregnancy desire/lower perceived difficulty. Findings represent a step towards elucidating pathways linking CM with AP. Recommendations are offered to prevent pregnancy by addressing the pregnancy-specific mechanisms that are part of the maltreatment sequelae.

ABSTRACT

Heterogeneity in the course of posttraumatic stress symptoms (PTSS) following a major life trauma such as childhood sexual abuse (CSA) can be attributed to numerous contextual factors, psychosocial risk, and family/peer support. The present study investigates a comprehensive set of baseline psychosocial risk and protective factors including online behaviors predicting empirically derived PTSS trajectories over time. Females aged 12-16 years (N = 440); 156 with substantiated CSA; 284 matched comparisons with various self-reported potentially traumatic events (PTEs) were assessed at baseline and then annually for 2 subsequent years. Latent growth mixture modeling (LGMM) was used to derive PTSS trajectories, and least absolute shrinkage and selection operator (LASSO) logistic regression was used to investigate psychosocial predictors including online behaviors of trajectories. LGMM revealed four PTSS trajectories: resilient (52.1%), emerging (9.3%), recovering (19.3%), and chronic (19.4%). Of the 23 predictors considered, nine were retained in the LASSO model discriminating resilient versus chronic trajectories including the absence of CSA and other PTEs, low incidences of exposure to sexual content online, minority ethnicity status, and the presence of additional psychosocial protective factors. Results provide insights into possible intervention targets to promote resilience in adolescence following PTEs.

ABSTRACT

OBJECTIVES: Deviations from normative trajectories of receptive language abilities following early life adversity (ELA) may indicate an elevated risk for advanced cognitive aging and related morbidities. Accelerated epigenetic aging at midlife may further identify those at greatest risk for advanced cognitive aging following ELA. We examined whether accelerations in epigenetic aging at midlife can identify those individuals who demonstrated the greatest change in receptive language abilities following ELA. METHODS: Data were drawn from the Female Growth and Development Study (n = 86), a 30-year prospective cohort study of females exposed to substantiated child sexual abuse (CSA), a severe ELA, and a non-CSA comparison condition. The Peabody Picture Vocabulary Test-Revised (PPVT-R) measured receptive language abilities on 6 occasions from childhood to mid-life. Interindividual differences in PPVT-R trajectories were examined in relation to CSA exposure and across 5 independent measures of epigenetic age acceleration derived from first (Horvath DNAmAge, Hannum DNAmAge) and second (GrimAge, PhenoAge, Dunedin Pace of Aging) generation epigenetic clocks. RESULTS: Quadratic growth models revealed that PPVT-R scores were significantly lower at age 25 for females exposed to CSA. Specifically, CSA exposed females had lower intercepts when GrimAge was accelerated and a smaller quadratic trend when PhenoAge was accelerated. DISCUSSION: ELA is associated with significant differences in development of receptive language abilities with the most pronounced differences observed for females with accelerated epigenetic ages at mid-life. These findings suggest that epigenetic age acceleration could serve as an indicator of differences in cognitive aging and portend to later adulthood cognitive functioning.

ABSTRACT

The present study elucidates heterogeneity in post-traumatic stress symptoms (PTSS) across adolescence in a sample of youth who have experienced myriad types and combinations of potentially traumatic events (PTEs), including substantiated physical abuse, sexual abuse, neglect and/or at least one other self-reported PTE. A machine learning technique was used to assess a multivariate set of variables (e.g., PTEs, individual risk and protective factors, social risk and protective factors, and racial and ethnic minority status) as predictors of PTSS trajectory group membership. The sample included 498 maltreated (n = 275) and comparison (n = 223) 14-19-year-old female adolescents (M = 15.27, SD = 1.06 at Time 1) assessed annually until age 19. 45.7% of participants were White, 45.3% Black, 0.4% Native American, 0.8% Hispanic, and 7.7% other. Growth mixture modeling identified three distinct trajectories of PTSS: (1) recovery (56%); (2) moderate, chronic (25%); and (3) high, chronic (19%). An elastic net model was used to test predictors of membership in the recovery versus the high, chronic PTSS trajectory groups. Results demonstrated that the recovery trajectory was characterized by the absence of sexual abuse, physical abuse, and other traumas, higher self-esteem, less affective dysregulation, less risky peers, lower levels of parent depression, and being of racial/ethnic minority status. Findings help to characterize individual variation in trajectories of PTSS following PTEs by underscoring the unique trauma responses of racial and ethnic minority youth and offering possible targets of interventions to promote recovery from PTSS.

ABSTRACT

An association between adverse childhood experiences (ACEs) and elevated body mass index (BMI) has been found in previous investigations. ACEs' effects on BMI have been primarily considered via individual-level physiological and behavioral frameworks. Neighborhood factors, such as greenspace, are also associated with BMI and may merit consideration in studies examining ACEs-BMI associations. This exploratory study examined associations of BMI with ACEs and neighborhood greenspace and tested whether greenspace moderated ACEs-BMI associations. Methods entailed secondary analysis of cross-sectional data. ACEs and BMI were captured from 2012/2013 Philadelphia ACE Survey and 2012 Southeastern Household Heath Survey data; greenspace percentage in participants' (n = 1,679 adults) home neighborhoods was calculated using National Land Cover Database data. Multi-level, multivariable linear regression 1) examined associations between BMI, ACEs, (0 ACEs [reference], 1-3 ACEs, 4 + ACEs), and neighborhood greenspace levels (high [reference], medium, low) and 2) tested whether greenspace moderated the ACEs-BMI association (assessed via additive interaction) before and after controlling for sociodemographic and health-related covariates. Experiencing 4 + ACEs (ß = 1.21; 95 %CI: 0.26, 2.15; p = 0.01), low neighborhood greenspace (ß = 1.51; 95 %CI: 0.67, 2.35; p < 0.01), and medium neighborhood greenspace (ß = 1.37; 95 %CI: 0.52, 2.21; p < 0.01) were associated with BMI in unadjusted models. Only low neighborhood greenspace was associated with BMI (ß = 0.95; 95 %CI: 0.14, 1.75; p = 0.02) in covariate-adjusted models. The ACEs-greenspace interaction was not significant in unadjusted (p = 0.89-0.99) or covariate-adjusted (p = 0.46-0.79) models. In conclusion, when considered simultaneously, low neighborhood greenspace, but not ACEs, was associated with BMI among urban-dwelling adults in covariate-adjusted models.
