Meeting Report: The Role of Beliefs and Perception on Body Size. Proceedings of the 26th Aschauer Soiree, Held at Aschauhof, Altenhof, Germany, May 26th, 2018.

Thirty-one scientists met at Aschauhof, Germany to discuss the role of beliefs and self-perception on body size. In view of apparent growth stimulatory effects of dominance within the social group that is observed in social mammals, they discussed various aspects of competitive growth strategies and growth adjustments. Presentations included new data from Indonesia, a cohort-based prospective study from Merida, Yucatan, and evidence from recent meta-analyses and patterns of growth in the socially deprived. The effects of stress experienced during pregnancy and adverse childhood events were discussed, as well as obesity in school children, with emphasis on problems when using z-scores in extremely obese children. Aspects were presented on body image in African-American women, and body perception and the disappointments of menopause in view of feelings of attractiveness in different populations. Secular trends in height were presented, including short views on so called 'racial types' vs bio-plasticity, and historic data on early-life nutritional status and later-life socioeconomic outcomes during the Dutch potato famine. New tools for describing body proportions in patients with variable degrees of phocomelia were presented along with electronic growth charts. Bio-statisticians discussed the influence of randomness, community and network structures, and presented novel tools and methods for analyzing social network data.

Abnormal body weight and food-related behavior in school-aged children as measured by the Children's Binge Eating Disorder Scale.

Obesity in children is becoming a global epidemic. Health and emotional consequences can threaten life and health both during childhood and adulthood. In this study, we aimed to assess the coexistence of overweight and obesity, binge eating disorder and detrimental attitudes toward nutrition among school-age children. We also aimed to determine the usefulness of the Children's Binge Eating Disorder Scale (C-BEDS) as a screening tool. We examined a group of over 550 healthy children aged 6-12. In all, 15% were overweight, and 6% were obese. A total of 12% of the children presented an increased risk of eating disorders. The examined group of children significantly differed in the number of positive C-BEDS responses compared with the authors of the test. Test reliability as measured by the Cronbach's alpha coefficient was .008. Preliminary results indicate that the problem of excessive body weight affects every fifth child, consistent with previous reports. The C-BEDS used in this study did not permit the identification of children, neither with the risk of Binge Eating Disorder (BED) nor subthreshold BED. This may be due to the relatively low internal consistency of the questions contained in the scale.

Excessive Weight Gain and Dental Caries Experience among Children Affected by ADHD.

In recent years, attention has been paid to the co-occurrence of attention deficit hyperactivity disorder (ADHD) and obesity, but results in relation to dental caries outcomes differ. The study was conducted to determine obesity/overweight and dental caries in children suffering from ADHD and to draw comparisons with non-ADHD children. A total of 119 children under 11 years old (8.2 ± 1.2) were enrolled into a cross-sectional study: those with confirmed ADHD (n = 39), and healthy controls (n = 80). The behavioral evaluation included a parent interview directed at sweetened food/drink habits. The clinical evaluation included physical measurements (height, waist, hip circumference, body weight, body mass index (BMI), and dental examination (International Caries Detection and Assessment System-ICDAS). Results showed a higher prevalence of abnormal body weight, hip circumference, and BMI, and a higher frequency of caries (84.6%) in the ADHD group. Significant caries differences for primary (ICDAS 0, 1, 2, 5, 6 scores) and permanent teeth (ICDAS 1, 3 scores) were recorded. The questionnaire pinpointed interplays between sugar consumption and tooth decay, especially for primary dentition. It can be concluded that the consumption of sweetened foods/drinks among ADHD children may lead to an increased rate of overweight, but may also affect oral health. Limiting sugar consumption might be one of the important elements in prevention programmes against dental caries and overweight/obesity.

The association of the executive functions with overweight and obesity indicators in children and adolescents: A literature review.

The prevalence of obesity in children and adolescents has become an increasing health problem all over the world. Prior studies suggest there is a relationship between excess body mass in adults and executive functions (EF). The paper analyzes recent studies on the association of obesity indicators and EF performance in children and adolescents. We analyzed four types of studies: comparison studies with obese and healthy children, cross-sectional studies describing dependencies between EF and BMI, follow up studies applying EF as a predictor of overweight/obesity and studies describing the effect of weight reduction on improving EF. We interpreted the results based on the categorization of EF into three main processes: inhibitory control, working memory, cognitive flexibility, and higher-level EF such as reasoning, problem-solving and planning. The strongest evidence supports the relationship between poor inhibitory control and higher BMI, overweight or obesity. However, the mechanism of the association is still unclear. A better understanding of the EF-obesity link may be relevant for the prevention of obesity or help in EF deficits improvement.
