This study aimed to identify binge-eating behavior and food addiction in Korean population and to determine their associations with obesity, eating behaviors, mental health and cognitive characteristics. We collected clinical questionnaire scores related to eating problems (e.g. binge eating, food addiction, food cravings), mental health (e.g. depression), and cognitive functions (e.g. impulsivity, emotion regulation) in 257 Korean adults in the normal and the obese weight ranges. Binge-eating and food addiction were most frequent in obese women (binge-eating: 46.6%, food addiction: 29.3%) when we divided the participants into 4 groups depending on gender and obesity status. The independence test using the data with propensity score matching confirmed that binge-eating and food addiction were more prevalent in obese individuals. Finally, we constructed the logistic regression models using forward selection method to evaluate the influence of various clinical questionnaire scores on binge-eating and food addiction respectively. Binge-eating was significantly associated with the clinical scales of eating disorders, food craving, state anxiety, and emotion regulation (cognitive reappraisal) as well as food addiction. Food addiction demonstrated the significant effect of food craving, binge-eating, the interaction of obesity and age, and years of education. In conclusion, we found that binge-eating and food addiction are much more frequent in females and obese individuals. Both binge-eating and food addiction commonly involved eating problems (e.g. food craving), but there was difference in mental health and cognitive risk factors. Therefore, it is required to distinguish food addiction from binge-eating and investigate intrinsic and environmental risk factors for each pathology.

Objects：It is difficult to differentiate between attention deficit hyperactivity disorder(ADHD) and mania because of similar symptoms and atypical symptoms of mania in children and adolescents. The purpose of this study is to identify the characteristics and to clarify the relationship by comparing the clinical features and comorbidities of ADHD and manic patients. Methods：The subjects consisted of 35 patients with ADHD and 19 manic patients. To Compare the characteristic symptoms between the two disorders, we selected 29 patients with ADHD and 14 patients with manic disorders. 6 ADHD patients who had manic disorders as comorbid disorder, and 5 manic patients who had ADHD as comorbid disorders were manic disorders were excluded. Results：1) There were significant differences in ages of onset and state anxiety scale scores, birth weights, numbers of perinatal problem, gestational ages, school behavioral problems between ADHD patients and manic patients(p<0.01). 2) There were significant differences in loses things(p<0.05) of ADHD-symptoms and grandiosity(p<0.01), decrease in sleep(p<0.05), delusions(p<0.01), hallucinations(p<0.05) of mania-symptoms between ADHD patients and manic patients. 3) The comorbid disorders of ADHD patients are significantly high(p<.05) than that of manic patients in major depression. 4) The familial loading of manic patients are significantly high(p<.05) than that of ADHD patients in mood disorder. Conclusions：The above results suggest that ADHD and mania are different disorders, considering the significant differences of clinical features and characteristics, familial loadings of the two disorders.
