Background: Type 2 diabetes (T2D) and depression co-occur, and rates are on the rise in adolescents, disproportionately affecting teenagers in rural communities and those who identify as members of historically disadvantaged racial/ethnic groups. Addressing the promotion of health behaviors is important for prevention of these comorbid health concerns; however, disparities in their prevalence highlight that a healthy lifestyle is not equally accessible for all individuals. Thus, holistic and multi-level approaches that address structural inequities, leverage cultural and family assets, and are effectively integrated into the community are critically needed.

Introduction: Sleep is an essential factor for health and wellbeing in people across the age spectrum; yet many adolescents do not meet the recommended 8-10 h of nightly sleep. Unfortunately, habitually insufficient sleep, along with the metabolic changes of puberty, puts adolescents at increased risk for a host of adverse health outcomes such as obesity and type 2 diabetes (T2D). Furthermore, individuals from historically minoritized racial and ethnic groups (e.

Background: Negative affect is prevalent among adolescents with type 1 diabetes (T1D) and may impact diabetes self-management and outcomes through stress-related behaviors such as disordered eating.

Methods: We describe the development of and design for the adaptation of a mindfulness-based intervention (MBI) for adolescents with T1D and negative affect. BREATHE-T1D is an MBI designed to target negative affect that has been tailored to address the unique lived experiences of adolescents with T1D.

Objective: Among adolescents, disinhibited eating and anxiety commonly co-occur. Precision intervention approaches targeting unique mechanistic vulnerabilities that contribute to disinhibited eating and anxiety may therefore be helpful. However, the effectiveness of such interventions hinges on knowledge of between- and within-person associations related to disinhibited eating, anxiety, and related processes.

Objective: Asthma disproportionately impacts youth who have been systemically marginalized and underserved, henceforth termed underserved for brevity. Disparities are driven by systemic and structural racism and social determinants of health. We aimed to synthesize findings from interventions delivered among youth who have been underserved, highlight effective intervention strategies, and provide recommendations to promote health equity.

Objective: Loss-of-control and overeating are common in adolescents with high body mass index (BMI). Mindfulness may affect negative affect, and both may relate to loss-of-control and overeating. Yet, there is limited understanding of these associations in adolescents' daily lives.

(1) Background: Standard-of-care lifestyle interventions show insufficient effectiveness for the prevention and treatment of excess weight and its associated cardiometabolic health concerns in adolescents, necessitating more targeted preventative approaches. Anxiety symptoms are common among adolescents, especially girls at risk for excess weight gain, and have been implicated in the onset and maintenance of disinhibited eating. Thus, decreasing elevated anxiety in this subset of adolescent girls may offer a targeted approach to mitigating disinhibited eating and excess weight gain to prevent future cardiometabolic health problems.

Objective: The extent to which tailored executive functioning (EF) interventions lead to improvements in other areas of functioning in adolescents with epilepsy is unknown. The types of problems that youth select to practice EF skills during tailored interventions has not been documented. This study aimed to systematically evaluate: 1) the EF problems and strategies selected during a tailored EF intervention for youth with epilepsy, and 2) impact of a tailored intervention on specific problems for subgroups who choose to practice EF skills in those areas.

Background: Pediatric solid organ transplant recipients are susceptible to posttraumatic stress symptoms (PTSS), given the presence of a life-threatening chronic medical condition and potential for complications. However, little is known about what individual characteristics are associated with an increased risk for PTSS among youth who received an organ transplant. The aim of the current study was to evaluate PTSS and its associations with executive functioning (EF) and personality (i.

Background: It is widely assumed that pediatric solid organ transplantation results in better caregiver-reported outcomes, including reduced caregiver psychological distress and increased child health-related quality of life (HRQOL), yet little empirical evidence of this expectation exists. The current investigation aims to fill this gap and identify key clinical course factors predictive of caregiver-reported outcomes.

Methods: Forty-nine caregivers of children (M  = 10.

Adolescents with epilepsy are at risk for deficits in working memory, which could lead to learning difficulties and poor academic outcomes. We used task-based functional magnetic resonance imaging (fMRI) to examine potential disruption in working memory function in adolescents with epilepsy as compared to healthy controls. We recruited 29 adolescents (13-17 years) with non-lesional epilepsy and 20 healthy controls.
