Little research on the prevalence and correlates of adult ADHD has been conducted outside the United States. The aim of the present study was to estimate the prevalence and correlates of adult ADHD in a large representative sample of the German population aged 18-64 years (n = 1,655). Two self-rating screening instruments to assess childhood and adult ADHD symptomatology were used to estimate the prevalence of ADHD. A 4-item screening tool was used to assess probable cases of current depression and anxiety (Patient Health Questionnaire). The estimated crude prevalence rate of current ADHD was 4.7%. Adult ADHD was significantly associated with lower age, low educational level, unemployment, marital status (never married and divorced), and rural residency. No association was found with gender. Adult ADHD was strongly associated with positive screening results for depression and anxiety. ADHD is a common disorder of adulthood, is associated with significant social impairment and psychiatric co-morbidity, and should receive further research attention.

Objective: The goal of the present study was to examine the association between attention-deficit/hyperactivity disorder (ADHD) and obesity in a representative community based sample of the German population. Method: Participants were 1,633 German residents (53.6% female) aged 18–64 years. A retrospective assessment of childhood ADHD and a self-report assessment of adult ADHD were administered for diagnosis of adult ADHD. In addition, binge eating and purging behaviors as well as depression and anxiety were assessed using selfrating instruments. Results: The estimated prevalence of ADHD in obese participants was 9.7% compared to 3.8% in overweight and 4.3% in under-/normal-weight participants. The prevalence of obesity was 22.1% among adults with ADHD and 10.2% among persons without ADHD. Adult ADHD was significantly associated with a greater likelihood of being obese but not overweight even after adjusting for sociodemographic characteristics. Results were similar when adjusting for depression and anxiety symptoms and for purging behaviors. Odds ratios decreased after adjusting for binge eating; however, the results were still significant which shows that the relationship between obesity and ADHD in adulthood is not fully explained by binge eating. Conclusion: Overall, the results indicate that adult ADHD is associated with obesity in a community-based sample of the adult German population.

Our results suggest that carers themselves have high levels of needs which are usually not addressed in clinical practice.

BackgroundA constant preoccupation with food and restrictive eating are main symptoms of anorexia nervosa (AN). Imaging studies revealed aberrant neural activation patterns in brain regions processing hedonic and reward reactions as well as–potentially aversive–emotions. An imbalance between so called “bottom-up” and “top-down” control areas is discussed. The present study is focusing on neural processing of disease-specific food stimuli and emotional stimuli and its developmental course in adolescent and adult AN patients and could offer new insight into differential mechanisms underlying shorter or more chronic disease.Methods33 adolescents aged 12–18 years (15 AN patients, 18 control participants) and 32 adult women (16 AN patients, 16 control participants) underwent functional magnetic resonance imaging (fMRI, 3T high-field scanner) while watching pictures of high and low-calorie food and affective stimuli. Afterwards, they rated subjective valence of each picture. FMRI data analysis was performed using a region of interest based approach.ResultsPictures of high-calorie food items were rated more negatively by AN patients.Differences in activation between patients and controls were found in “bottom up” and “top down” control areas for food stimuli and in several emotion processing regions for affective stimuli which were more pronounced in adolescents than in adults.ConclusionA differential pattern was seen for food stimuli compared to generally emotion eliciting stimuli. Adolescents with AN show reduced processing of affective stimuli and enhanced activation of regions involved in “bottom up” reward processing and “top down” control as well as the insula with regard to food stimuli with a focus on brain regions which underlie changes during adolescent development. In adults less clear and less specific activation differences were present, pointing towards a high impact that regions undergoing maturation might have on AN symptoms.
