A Universal Program to Improve Mental Health among Youth from Low-Income Predominantly Minority Communities: Implementation of Advocates 4 ALL Youth (ALLY).

Disparities in mental health care and access to care disproportionately affect youth from minoritized and low-income communities. School-based prevention programs have the potential to offer a non-stigmatized approach to mental health care as well as the ability to reach many students simultaneously. Advocates 4 All Youth (ALLY) is a program developed for 5-6th grade students aimed at improving self-efficacy and resilience via individualized sessions with a trusted adult (ALLYs).

A call to create evidence-based mental health promotion interventions for youth that are equitable across ethnic/racial subgroups: Advocates 4-ALL Youth.

Background: Adolescents from historically racial and ethnic minoritized and low-income communities have higher rates of early-life and chronic difficulties with anxiety and depression compared to non-Hispanic White youth. With mental health distress exacerbated during and in the wake of the COVID-19 pandemic, there is a need for accessible, equitable evidence-based programs that promote psychological well-being, strengthen one's ability to adapt to adversity, and build self-efficacy prior to adolescence.

Methods: An evidenced-based resiliency-focused health coaching intervention was adapted using a health equity implementation framework to meet the needs of a Title I elementary school in rural Alabama (AL) that serves over 80% Black and Hispanic students.

The Effects of Virtual Zumba ® on Functional Outcomes in Adults with Developmental Disabilities.

Introduction: Few studies have examined the comprehensive impact of adaptive exercise interventions across multiple functional domains (i.e., physical and cognitive health) in adults with developmental disabilities (DD).

Academic learning time in physical education (ALT-PE) during an adapted tennis program for children with autism spectrum disorders.

As the prevalence of autism spectrum disorder (ASD) increases, there is a growing need to develop physical activity interventions that address the behavioral challenges experienced by individuals with ASD. Physical education teachers have employed behavioral supports that add more structure and adapt the environment for individuals with ASD, which are associated with increased engagement for individuals with ASD during PE. The purpose of this study was to quantify motor engaged behaviors (i.

Improvements in Swim Skills in Children with Autism Spectrum Disorder Following a 5-Day Adapted Learn-To-Swim Program (iCan Swim).

Drowning is one of the leading causes of death in children and teenagers. Individuals with autism spectrum disorder (ASD) are at increased risk for drowning. Improvements in swim skills have been observed in children with ASD participating in learn-to-swim programs.

Effects of music tempo on perceived exertion, attention, affect, heart rate, and performance during isometric strength exercise.

This study examined the effects of slow and fast music tempi on effort-related thoughts, rating of perceived exertion (RPE), affect, heart rate, and performance during isometric strength exercises. Participants were randomly assigned to one of three conditions (no-music control, fast-tempo music, and slow-tempo music) and performed two isometric strength exercises (wall-sit and plank). RPE, attention allocation, and affect were measured during each exercise task.

A Systematic Review of the Effectiveness of Concussion Education Programs for Coaches and Parents of Youth Athletes.

Coach and parent concussion education programs are essential for the prevention, diagnosis, management, and return to play of youth athletes. This systematic review examined the content and efficacy (changes in knowledge, impact on concussion incidence) of concussion education programs for coaches and parents of youth and high school athletes. Six databases were searched: SPORTDiscus, Academic Search Premiere, CINAHL, PsycINFO, PubMed, and Google Scholar.

Intervention Strategies to Elicit MVPA in Preschoolers during Outdoor Play.

Approximately 50% of preschoolers do not meet physical activity recommendations and children who reside in low-income rural communities may be further at risk for higher levels of sedentary behavior. Outdoor play is essential for preschool children; however, literature is unclear as to which types of interventions elicit moderate-to-vigorous physical activity (MVPA) for all preschoolers. The aim of this study was to determine which type of intervention, physical activity or fundamental motor skill focus, elicits MVPA during outdoor play.

A Systematic Review and Meta-Analysis of School-Based Stress, Anxiety, and Depression Prevention Programs for Adolescents.

Given the recent rise in adolescent mental health issues, many researchers have turned to school-based mental health programs as a way to reduce stress, anxiety, and depressive symptoms among large groups of adolescents. The purpose of the current systematic review and meta-analysis is to identify and evaluate the efficacy of school-based programming aimed at reducing internalizing mental health problems of adolescents. A total of 42 articles, including a total of 7310 adolescents, ages 11-18, met inclusion for the meta-analyses.

A systematic review of acute concussion assessment selection in research.

Several organisations developed guidelines and assessments for aiding in the diagnosis of concussions. The growing number of concussion assessments increases the difficulty for researchers and clinicians to determine the best method of concussion diagnosis. To systematically review the current assessments selected for acute sports-related concussion.

Effects of cannabinoid administration for pain: A meta-analysis and meta-regression.

Chronic pain states have resulted in an overreliance on opioid pain relievers, which can carry significant risks when used long term. As such, alternative pain treatments are increasingly desired. Although emerging research suggests that cannabinoids have therapeutic potential regarding pain, results from studies across pain populations have been inconsistent.

Motor skills assessments: support for a general motor factor for the Movement Assessment Battery for Children-2 and the Bruininks-Oseretsky Test of Motor Proficiency-2.

Objective: To evaluate the construct validity and model-based reliability of general and specific contributions of the subscales of the Movement Assessment Battery for Children-2 (MABC-2) and Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) when evaluating motor skills across a range of psychiatric disorders.

Methods: Confirmatory factor analysis (CFA) and bifactor analysis were conducted on BOT-2 data from 187 elementary school students (grades 1 to 6) (mean age: 113 ± 20 months; boys: n = 117, 62.56%) and on MABC-2 data from 127 elementary school students (grade 1) (mean age: 76 ± 2 months; boys: n = 58, 45.

The trajectory of balance skill development from childhood to adolescence was influenced by birthweight: a latent transition analysis in a British birth cohort.

Objective: To identify classes of balance skills and their trajectories from childhood to adolescence and the association of birthweight with these trajectories.

Study Design And Setting: Participants (n = 13,443) from the 1970 British Cohort Study were assessed for four balance skills in childhood and adolescence. Latent class analysis was used to determine classes of balance skills over time, and latent transition analysis was used to explain the association between birthweight and the probabilities of changing classes over time.

A new motor screening assessment for children at risk for motor disorders: construct validity.

Objective: To develop a motor screening assessment and provide preliminary evidence of its psychometric properties.

Methods: A sample of 365 elementary school students was assessed, with structural equation modeling applied to obtain evidence of the adequacy of the factor structure of the motor screening assessment. As well, differential item functioning was used to evaluate whether various identifiable subgroups of children (i.

Influence of birthweight on childhood balance: Evidence from two British birth cohorts.

Background: Birthweight is an important predictor of various fundamental aspects of childhood health and development.

Aim: To examine the impact of birthweight on childhood balance performance classification and verify if this is replicable and consistent in different populations.

Study Design: Prospective birth cohort study.

Motor skills intervention research of children with disabilities.

Background: Physical inactivity and obesity among children with physical and cognitive disabilities is an emerging public health issue. Children's motor skill development is a determinant of lifelong physical activity and obesity.

Aims: The purpose of this article is to critically evaluate motor skill intervention literature among children with physical and cognitive disabilities.

Associations between prenatal, childhood, and adolescent stress and variations in white-matter properties in young men.

Objective: Previous studies have shown that both pre- and post-natal adversities, the latter including exposures to stress during childhood and adolescence, explain variation in structural properties of white matter (WM) in the brain. While previous studies have examined effects of independent stress exposures within one developmental period, such as childhood, we examine effects of stress across development using data from a prospective longitudinal study. More specifically, we ask how stressful events during prenatal development, childhood, and adolescence relate to variation in WM properties in early adulthood in young men recruited from a birth cohort.

Age- and sex-related variations in vocal-tract morphology and voice acoustics during adolescence.

Distinct differences in the human voice emerge during adolescence, with males producing deeper and more resonant voices than females by the end of sexual maturation. Using magnetic resonance images of heads and voice recordings obtained in 532 typically developing adolescents, we investigate what might be the drivers of this change in voice, and the subjective judgment of the voice "maleness" and "femaleness". We show clear sex differences in the morphology of voice-related structures during adolescence, with males displaying strong associations between age (and puberty) and both vocal-fold and vocal-tract length; this was not the case in female adolescents.

Early Cannabis Use, Polygenic Risk Score for Schizophrenia and Brain Maturation in Adolescence.

Importance: Cannabis use during adolescence is known to increase the risk for schizophrenia in men. Sex differences in the dynamics of brain maturation during adolescence may be of particular importance with regard to vulnerability of the male brain to cannabis exposure.

Objective: To evaluate whether the association between cannabis use and cortical maturation in adolescents is moderated by a polygenic risk score for schizophrenia.

The effect of lifelong bilingualism on regional grey and white matter volume.

Lifelong bilingualism is associated with the delayed diagnosis of dementia, suggesting bilingual experience is relevant to brain health in aging. While the effects of bilingualism on cognitive functions across the lifespan are well documented, less is known about the neural substrates underlying differential behaviour. It is clear that bilingualism affects brain regions that mediate language abilities and that these regions are at least partially overlapping with those that exhibit age-related decline.

Puberty and testosterone shape the corticospinal tract during male adolescence.

Some of the known sex differences in white matter emerge during adolescence. Here, we replicate and extend our previous findings of sex differences in the structure of the corticospinal tract (Perrin et al. 2009; Hervé et al.

Adiposity is associated with structural properties of the adolescent brain.

Obesity, a major risk factor for cardiometabolic disease, is associated with variations in a number of structural properties in the adult brain, as assessed with magnetic resonance imaging (MRI). In this study, we investigated the cross-sectional relationship between visceral fat (VF), total body fat (TBF) and three MRI parameters in the brains of typically developing adolescents: (i) T1-weighted (T1W) signal intensity; (ii) T1W signal contrast between white matter (WM) and gray matter (GM); and (iii) magnetization transfer ratio (MTR). In a community-based sample of 970 adolescents (12-18 years old, 466 males), VF was quantified using MRI, and total body fat was measured using a multifrequency bioimpedance.

Differences in movement-related cortical activation patterns underlying motor performance in children with and without developmental coordination disorder.

Behavioral deficits in visuomotor planning and control exhibited by children with developmental coordination disorder (DCD) have been extensively reported. Although these functional impairments are thought to result from "atypical brain development," very few studies to date have identified potential neurological mechanisms. To address this knowledge gap, electroencephalography (EEG) was recorded from 6- to 12-yr-old children with and without DCD (n = 14 and 20, respectively) during the performance of a visuomotor drawing task.
