Objective: To assess prevalence and socioeconomic context of overweight and obesity in a cohort of Scottish children.
Design: Cross-sectional study.
Setting: Primary schools in Dundee, Angus, and Fife, Eastern Scotland, UK.
Participants: A total of 1240 boys and 1214 girls aged between 4-10 y.
Main Outcome Measure: Weight, height and body mass index (weight/height2).
Results: Overall overweight or obesity prevalence was 24.6%, while prevalence of obesity alone was 6.1%. Individuals from schools with a high level of low-income families were 65% more likely to be overweight as judged by BMI. However, these children weighed the same as more affluent children of the same age, but were 1.26 cm shorter.
Conclusion: These data confirm the continued increase in childhood obesity in the UK and reveal a role for height-growth limitation in the absence of overall growth restriction, among children from low-income groups. This observation raises important questions regarding socioeconomic environmental factors in promoting the currently increasing levels of obesity.

Pediatric obesity and the risk of multiple sclerosis: a nationwide prospective cohort study.
Int J Obes (Lond)

Background: Emerging evidence implies a link between high pediatric body mass index (BMI) and an increased risk of multiple sclerosis (MS). However, previous research suggests this association is only present for adolescent obesity and not childhood obesity. The present study aimed to assess the association between pediatric obesity and risk of developing MS, and to investigate if degree of obesity and age at obesity treatment initiation affects the risk.

Brown and beige adipocytes express uncoupling protein-1 (UCP1), which is located in the inner mitochondrial membrane and facilitates the dissipation of excess energy as heat. The activation of thermogenic adipocytes is a potential therapeutic target for treating type 2 diabetes mellitus, obesity, and related co-morbidities. Therefore, identifying novel approaches to stimulate the function of these adipocytes is crucial for advancing therapeutic strategies.

Purpose: The purpose of this study is to describe the association between the volume and intensity of accelerometer-assessed physical activity (PA) and markers of obesity.
Method: Forty-seven children (20 girls) took part in this investigation. Children wore accelerometers on their nondominant wrists for 7 days.
Introduction: Metabolic and bariatric surgery (MBS) is increasingly used for obesity and metabolic disease, with safety profiles showing it is among the safest major operations. The last 20 + years have noted significantly improved safety that has been accompanied by decreasing length of stay and select populations electing for outpatient surgery, leading to continued decreases in cost. Regardless, readmissions and complications still occur, requiring inpatient postoperative care (IP-POC).

Background: Precision nutrition-based methods develop tailored interventions and/or recommendations accounting for determinants of intra- and inter-individual variation in response to the same diet, compared to current 'one-size-fits-all' population-level approaches. Determinants may include genetics, current dietary habits and eating patterns, circadian rhythms, health status, gut microbiome, socioeconomic and psychosocial characteristics, and physical activity. In this systematic review, we examined the evidence base for the effect of interventions based on precision nutrition approaches on overweight and obesity in children and adolescents to help inform future research and global guidelines.
