Although childhood maltreatment is associated with long-term impairment, some children function well despite this adversity. This study aimed to identify the key protective factors for good educational attainment and positive emotional health in adolescents who experienced maltreatment in early childhood. Data were analyzed from the Avon Longitudinal Study of Parents and Children, a large UK prospective cohort study. The sample was defined by maternally reported exposure to physical or emotional maltreatment by a parent prior to 5 years...

Objectives: Evidence in adults suggests that improvements in cognitive performance may follow weight loss resulting from bariatric surgery, and baseline cognitive performance may be associated with weight loss following surgery. This has not been evaluated in adolescents. Method: Participants were 38 adolescents of age 14-21 years composed of three groups: (1) 12 adolescents with severe obesity who received vertical sleeve gastrectomy during the study (VSG); (2) 14 adolescents with severe obesity who were wait-listed for VSG (WL); and (3) 12 healthy weight controls (HC)...

Cognitive control, which relies on the protracted development of frontal-parietal regions into adolescence, is a brain process that may be particularly vulnerable to the impact of childhood abuse. In this study, we used functional magnetic resonance imaging (fMRI) to examine associations between the age of onset of childhood abuse and alterations to the neural mechanisms supporting cognitive control in early adulthood, which have not been previously examined. During fMRI scanning, participants completed hybrid block/event-related versions of a classic color-word Stroop task as well as emotional Stroop tasks (threat and positive words)...

The exercise tolerance of Fontan patients is poorer than that of healthy people. Some previous studies reported that exercise tolerance can be improved in this population by cardiac rehabilitation. This study aimed to determine the factors associated with peak oxygen uptake (VO2) and to subsequently clarify the correlation between participation in sports club activities and variables related to exercise tolerance. Cardiopulmonary exercise tests were performed by 115 Fontan patients aged between 6 and 20 years...

BACKGROUND: Process evaluations are critical for interpreting and understanding outcome trial results. By understanding how interventions function across different settings, process evaluations have the capacity to inform future dissemination of interventions. The complexity of Get others Active (GoActive), a 12-week, school-based physical activity intervention implemented in eight schools, highlights the need to investigate how implementation is achieved across a variety of school settings...

Watching television or listening to music while exercising can serve as motivating factors, making it more pleasant to exercise for some people. However, it is unknown whether these stimuli influence food intake and/or physical activity energy expenditure (PAEE) for the remainder of the day, potentially impacting energy balance and weight control. We examined the effects of watching television or listening to music while exercising on post-exercise energy intake and expenditure. Our study was a randomized crossover design, in which 24 male adolescents (mean age: 14...
