Digital behavioral dietary interventions to promote a healthy diet among children and adolescents: a scoping review of technologies, design, behavioral theory, and assessed outcomes.

Background: Childhood overweight and obesity prevalence steeply increased during recent decades, prompting the development of many digital behavioral dietary interventions (DBDIs). However, a coherent overview is lacking, which is crucial for delineating research in this field.

Objective: This scoping review outlines the landscape of DBDIs for improving dietary behaviors in children and adolescents, including delivery modes, design and development approaches, behavioral theory, and outcomes assessed.

Impact of play restriction during the COVID-19 pandemic on mental well-being in children with a chronic condition.

Unlabelled: This study is to investigate the effects of social restrictions, induced by the COVID-19 pandemic, on play behavior, and the associations with mental well-being in children with a chronic physical condition. Additionally, we explored potential moderating effects of environmental factors. Data from the PROactive cohort study including children with a chronic physical condition was used.

Early-Life Risk Factors for Carotid Intima-Media Thickness and Carotid Stiffness in Adolescence.

Importance: Atherogenesis starts during childhood, making childhood and adolescence an important window of opportunity to prevent atherosclerotic cardiovascular disease later in life.

Objective: To identify early-life risk factors for preclinical atherosclerosis in adolescence.

Design, Setting, And Participants: This cohort study is part of the ongoing Wheezing Illness Study in Leidsche Rijn (WHISTLER) prospective birth cohort study, which includes 3005 healthy newborns born between December 2001 and December 2012 in the Leidsche Rijn area of Utrecht, the Netherlands.

Lower hair cortisol concentration in adolescent and young adult patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome and Q-Fever Fatigue Syndrome compared to controls.

Background: In patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), momentary cortisol concentrations in blood, urine, and saliva are lower compared to healthy controls. Long-term cortisol concentration can be assessed through hair, but it is unclear whether these concentrations are also lower. Additionally, it is unknown if lower cortisol extends to other patients suffering from persistent fatigue and how hair cortisol concentration (HCC) relates to fatigue levels.
