Objective: To record the prevalence of overweight and obesity in urban primaryschool children in relation to several socio-economic and demographic factors. Design: Cross-sectional. Setting/subjects: A representative sample of 729 schoolchildren (379 male and 350 female), aged 9-13 years, stratified by parental educational level, was examined in the urban region of Athens. Weight and height were measured using standard procedures. The International Obesity Task Force thresholds were used for the definition of overweight and obesity. Several socio-economic and demographic data and the child's 'popularity' score were also recorded with specifically designed standardized questionnaires.

The present study shows that obese children and adolescents were at greater risk for ID and IDA than their normal-weight peers. Low grade inflammation induced by excessive adiposity may be a reason for the observed low iron levels. This is also strengthened by the elevated serum ferritin levels, comprising an acute phase protein that is plausibly increased in inflammation.

Aim: Weight loss is shown to improve obesity-related health problems as long as it is maintained for a long term. The purpose of this systematic review was to investigate the association between binge eating disorder and weight management in overweight and obese adults. Methods: A systematic search following the preferred reporting items for systematic reviews and meta-analyses guidelines was conducted across PubMed, Ebsco and Cochrane Library from inception through December 2020 to identify studies that assessed the association between binge eating disorder and weight management (e.g., weight loss, weight gain and weight loss maintenance) in overweight and obese adults. We included studies that examined adults (≥18 years old) being overweight and obese with and without binge eating behaviour. Two authors independently screened and evaluated studies for methodological quality. Results: Nine articles were selected, including 3685 participants. Three of the included studies were randomised control trials and the remaining were observational studies. The majority of the studies included support that people who have binge eating disorder may have an additional barrier maintaining their weight loss compared to people who do not suffer from binge eating disorder. Conclusion: Our systematic review revealed that binge eating disorder may have a negative association with weight loss maintenance. Further well-conducted prospective cohort studies and randomised clinical trials are required to investigate the possible mechanisms and whether any such mechanisms are modifiable. These will lead us to more efficient strategies targeting weight management.
