Article Synopsis
- The study aimed to analyze how increasing sleep duration for one week affects insulin sensitivity (IS) in adolescents at risk for type 2 diabetes (T2D).
- Participants aged 13-18, who were at risk due to obesity and other factors, underwent a crossover study where their sleep time was manipulated over a structured period.
- Results showed that increasing sleep by 1 hour 30 minutes per night significantly improved insulin sensitivity by 20% compared to their usual and decreased sleep, suggesting that even small increases in sleep duration are beneficial for youth at risk of T2D.
Article Synopsis
- The study investigates the occurrence of severe obesity (SO) and global developmental delay (GDD) in Canadian preschool children, focusing on incidence, onset age, risk factors, and healthcare utilization.
- A total of 47 cases were identified, with an average age of 3.5 years; common issues included behavioral problems and respiratory concerns, and a significant percentage of affected children had mothers with obesity.
- Findings emphasize the need for early identification and referral for affected children, along with potential genetic testing to exclude known syndromic obesity conditions.
Background: There are well-recognized benefits of behavioral interventions that include exercise for children and adolescents with obesity. However, such behavioral weight management programs may precipitate unintended consequences. It is unclear if different exercise modalities impact eating behaviors differently in youth with obesity.

Study Objectives: Behavioral characteristics and outcomes of positive airway pressure (PAP) therapy in children with obesity and moderate-severe sleep-disordered breathing (SDB) have not been reported. Our aims were to 1) determine baseline behavioral/emotional symptoms of this population and characterize changes over time with PAP, and 2) examine associations between baseline behavioral/emotional symptoms and PAP adherence.
Methods: This multicenter prospective cohort study of children with obesity prescribed PAP for moderate-severe SDB assessed PAP adherence (≥ 4 h/night, >50% of nights, usage diaries, downloads) and compared behavioral/emotional characteristics with parent- and child-reported Conners Rating Scale (Conners) and the Child Behavior Checklist (CBCL) at baseline and 1 year after PAP prescription between adherent and nonadherent participants; scores at baseline were compared retrospectively between adherence groups.
Context: Resistance exercise training (strength training) and aerobic exercise training are both recommended for people with type 1 diabetes, but it is unknown whether adding resistance exercise provides incremental benefits in people with this condition who already perform aerobic exercise regularly.
Objective: This work aimed to evaluate the incremental effect of resistance training on glycated hemoglobin A1c (HbA1c), fitness, body composition, and cardiometabolic risk factors in aerobically active people with type 1 diabetes.
Methods: The Resistance Exercise in Already-active Diabetic Individuals (READI) trial (NCT00410436) was a 4-center, randomized, parallel-group trial.
