Abstract	Background It has been hypothesized that deficiencies in social cognition might influence the onset or maintenance of eating disorders. Deficits in two subdomains of social cognition are well documented in eating disorder patients: emotion perception and Theory of Mind (ToM). However, the causal direction is unclear, and the association between impaired social cognition and problematic eating prior to the development of any eating disorder has only been sparsely studied. Aim The aim of the present study is to investigate possible associations between problematic eating and social cognition in a general population of preadolescents. Methods & Materials The study is part of the Copenhagen Child Cohort 2000 (CCC2000) following 6090 children prospectively from birth. The cohort has been assessed in infancy (0-1y), preschool-age (5-7y), and preadolescence (11-12y), including measures of problematic eating and mental difficulties. At 11-12 years 1630 children attended a test of ToM (the Storybook Frederik), while problematic eating was measured using the Eating Pattern Inventory for Children. Mental disorders were assessed using the Development and Well-Being Assessment (DAWBA). Also, register data of hospital diagnosed eating or autism-spectrum disorders from 0-12 years of age are available. Results Analyses will be carried out during the winter/spring 2017 including logistic regression adjusting for possible moderators and mediators (gender, onset of puberty, mental disorders, cognitive function, socio-economic status, and body weight). The results will be ready for presentation at the congress. We expect to find cross-sectional associations between problematic eating and poor ToM in preadolescence, especially concerning restrictive eating patterns. Associations are expected to be only partly explained by weight-status, cognitive function, and comorbidity. With a significance level of 5% and power of 80% the study will be able to detect an association between impaired ToM and problematic eating with an OR of 2.
