ABSTRACT
OBJECTIVE: Food addiction is a phenotype characterised by an addiction-like attraction to highly processed foods. Adolescence is a sensitive period for developing addictive disorders. Therefore, a valid measure to assess food addiction in adolescents is needed. Accordingly, the aim of the study was to establish a categorical scoring option for the full version of the Yale Food Addiction Scale for Children 2.0 (YFAS-C 2.0), and to psychometrically validate the full YFAS-C 2.0. METHOD: The data stem from the Food Addiction Denmark (FADK) Project. Random samples of 3750 adolescents from the general population aged 13-17 years, and 3529 adolescents with a history mental disorder of the same age were invited to participate in a survey including the full version of the YFAS-C 2.0. A confirmatory factor analysis was carried out and the weighted prevalence of food addiction was estimated. RESULTS: The confirmatory factor analysis of the YFAS-C 2.0 supported a one-factor model in both samples. The weighted prevalence of food addiction was 5.0% in the general population, and 11.2% in the population with a history of mental disorder. CONCLUSIONS: The full version of the YFAS-C 2.0 is a psychometrically valid measure for assessing clinically significant food addiction in adolescents.

BACKGROUND & AIMS: Individuals can develop an addiction-like attraction towards highly processed foods, which has led to the conceptualization of food addiction, a phenotype linked to obesity. In this study, we investigated whether food addiction is associated with type 2 diabetes (T2D). METHODS: 1699 adults from the general population and 1394 adults from a population with clinically verified mental disorder completed a cross-sectional survey including the Yale Food Addiction Scale 2.0. Logistic regression was employed to examine the association between food addiction and T2D, the latter operationalized via Danish registers. RESULTS: Food addiction was strongly associated with T2D in the general population (adjusted odds ratio (AOR) = 6.7) and among individuals with mental disorder (AOR = 2.4) in a dose-response-like manner. CONCLUSION: This is the first study to demonstrate a positive association between food addiction and T2D in a general population sample. Food addiction may be a promising target for prevention of T2D.

Background: High rejection rates for referrals to child and adolescent mental health services (CAMHS) are common. The most cited reasons for rejection are that the child does not have a clinical need for assessment and poor quality of the referrals. However, studies of interventions aimed at improving appropriateness of referrals are sparse. Methods: In this randomized feasibility trial, we tested if the Development and Well-Being Assessment (DAWBA) as an adjunct to referral letters could improve accuracy of referral decisions made by CAMHS. The primary outcome of the study was the proportion of "correct" referral decisions. Results: The study included 160 children referred to CAMHS. Almost all (95.6%) participants fulfilled criteria for a mental disorder and 82.1% also reported high impact of symptoms. Compared to the group who did not complete the DAWBA, referral decisions for the DAWBA group showed higher sensitivity (0.63 vs. 0.83), specificity (0.30 vs. 0.42), and negative predictive value (0.14 vs. 0.36) as well as slightly higher positive predictive value (0.81 vs. 0.86). Conclusions: The use of the DAWBA as an adjunct to standard referral letters could lead to more correct referral decisions and reduce the proportion of wrongful rejection referrals to CAMHS.

PURPOSE: Adolescence is a high-risk period for development of addictive behavior. This may also apply to addiction-like eating of highly processed foods-commonly referred to as "food addiction". Adolescents with mental disorder may be at particularly elevated risk of developing food addiction as addiction often accompanies mental disorder. However, there are only few studies in adolescents investigating this potential comorbidity. Therefore, the primary aim of this study was to examine the food addiction symptom load, as measured by the dimensional Yale Food Addiction Scale for Children-version 2.0 (dYFAS-C 2.0), among adolescents with a clinically verified mental disorder. METHOD: A total of 3529 adolescents aged 13-17 were drawn from the Danish Psychiatric Central Research Register, stratified on six major diagnostic categories of mental disorders; psychotic disorders, affective disorders, anxiety disorders, eating disorders, autism spectrum disorders, and attention deficit disorders. Via their parents, these adolescents were invited to participate in a web-based survey. Data on health and socioeconomic factors from the Danish registers were linked to both respondents and non-respondents, allowing for thorough attrition analysis and estimation of weighted dYFAS-C 2.0 scores. RESULTS: A total of 423 adolescents participated in the survey (response rate 12.0%). The mean weighted dYFAS-C 2.0 total score was 13.9 (95% CI 12.6; 14.9) for the entire sample and varied substantially across the diagnostic categories being highest for those with psychotic disorder, mean 18.4 (95% CI 14.6; 14.9), and affective disorders, mean 19.4. (95% CI 16.3; 22.5). Furthermore, the dYFAS-C 2.0 total score was positively correlated with body mass index (BMI) (r = 0.33, p < 0.05). CONCLUSION: Food addiction symptomatology seems to be prevalent among adolescents with mental disorder, particularly affective and psychotic disorders. As obesity is a tremendous problem in individuals with mental disorder further investigation of food addiction in young people with mental disorder is called for. This could potentially aid in the identification of potential transdiagnostic targets for prevention and treatment of obesity in this group. LEVEL OF EVIDENCE: Level IV, Observational cross-sectional descriptive study combined with retrospective register data.

Studies have identified a higher prevalence of co-existing psychiatric and medical disorders in children with ADHD. There is a shortage of longitudinal studies providing an overview of potential medical disorders in children with ADHD. The objective of this study was to provide a broad overview of lifetime prevalence and relative risk of medical disorders in a nationwide Danish cohort of children with and without ADHD during the first 12 years of life. A population-based prospective follow-back cohort study used data from Danish national health registries to identify a cohort of all children born in Denmark between 1995 and 2002. The children were followed from birth until 12 years of age in two national registries. Children with ADHD had a significantly higher prevalence of recorded diagnoses across all included chapters of medical disorders in the ICD-10, except for neoplasms, where the association with ADHD was non-significant. The highest relative risk was observed for the chapter concerning diseases of the nervous system, with episodic and paroxysmal disorders being the most frequently registered underlying category. The findings indicate that children with ADHD have an increased risk of a broad range of medical disorders compared to the general population during the first 12 years of life, except for neoplasms.

AIM: To investigate parental help-seeking patterns prior to referral to outpatient child and adolescent mental health services (CAMHS), and whether type of symptoms or duration of mental health problems prior to referral influence help-seeking. SETTING: Child mental health services in Denmark involve several sectors collaborating based on stepped-care principles. Access to CAMHS is free of charge but requires a formal referral. METHODS: In this cross-sectional observational study, parents of 250 children were interviewed about pathways to outpatient CAMHS using the Children's Services Interview. RESULTS: The median parent-reported duration of mental health problems prior to referral to CAMHS was 6.0 (IQR 3.4-8.5) years for children referred for neurodevelopmental disorders compared to 2.8 (IQR 1.0-6.5) years for children referred for emotional disorders. Educational services were the first help-seeking contact for the majority (57.5%) but referrals to CAMHS were most frequently from healthcare services (56.4%), predominantly general practitioners. Educational services played a greater part in help-seeking pathways for children referred for neurodevelopmental disorders. CONCLUSION: The majority of children referred to CAMHS have mental health problems for years before referral. The delay in time-to-referral was most pronounced for children referred for neurodevelopmental disorders. Help-seeking pathways differ by symptom duration and type of symptoms.

PURPOSE: Obesity among adolescents is becoming increasingly prevalent and "food addiction" (addiction-like attraction to foods with high content of fat and refined carbohydrates) may be a potential contributor to this development. This study aimed to investigate the psychometric properties of the dimensional Yale Food Addiction Scale for Children version 2.0 (dYFAS-C 2.0) and to estimate the weighted mean score on the dYFAS-C 2.0 (as a measure of food addiction symptom load) among adolescents from the general Danish population. METHODS: A total of 3,750 adolescents aged 13-17 were randomly drawn from the general Danish population and invited to participate in a web-based survey. Data on health and socioeconomic factors from the Danish registers were linked to both respondents and non-respondents, which allowed for analysis of attrition. The total- and sex-stratified weighted mean dYFAS-C 2.0 scores were estimated using augmented inverse probability weighted estimation. RESULTS: A total of n = 576 (15.4%) adolescents participated in survey of whom 55.6% were female. The confirmatory factor analysis of the dYFAS-C 2.0 supported a one-factor model. The dYFAS-C 2.0 total score was associated with eating pathology, BMI z-scores, and ADHD symptomatology. The weighted mean dYFAS-C 2.0 score was 12.1 (95% CI: 11.2;12.9), 15.0 (95% CI: 13.9;16.2) for females and 9.5 (95% CI: 8.3;10.6) for males. CONCLUSIONS: The dYFAS-C 2.0 appears to be a psychometrically valid tool to assess symptoms of food addiction among adolescents. Food addiction symptom severity correlated positively with eating pathology (including restrained eating), BMI z-scores, and ADHD symptomatology. Level IV, observational cross-sectional descriptive study combined with retrospective register data.

OBJECTIVE: Substance use disorder is highly prevalent among individuals with mental disorders. However, it remains largely unknown whether this is also the case for "food addiction"-a phenotype characterized by an addiction-like attraction to predominantly highly processed foods with a high content of refined carbohydrates and fat. Therefore, the primary aim of this study was to estimate the weighted prevalence of food addiction among individuals with mental disorders. METHOD: A total of 5,000 individuals aged 18-62 were randomly drawn from eight categories of major mental disorders from the Danish Psychiatric Central Research Register and invited to participate in an online questionnaire-based survey, which included the Yale Food Addiction Scale 2.0. Data on health care and sociodemographics from the Danish registers were linked to all invitees-enabling comprehensive attrition analysis and calculation of the weighted prevalence of food addiction. RESULTS: A total of 1,394 (27.9%) invitees participated in the survey. Across all diagnostic categories, 23.7% met the criteria for food addiction. The weighted prevalence of food addiction was highest among individuals with eating disorders (47.7%, 95%CI: 41.2-54.2), followed by affective disorders (29.4%, 95%CI: 22.9-36.0) and personality disorders (29.0%, 95%CI: 22.2-35.9). When stratifying on sex, the prevalence of food addiction was higher among women in most diagnostic categories. DISCUSSION: Food addiction is highly prevalent among individuals with mental disorders, especially in those with eating disorders, affective disorders and personality disorders. Food addiction may be an important target for efforts aimed at reducing obesity among individuals with mental disorders.

BACKGROUND: The number of patients calling for an ambulance increases. A considerable number of patients receive a non-specific diagnosis at discharge from the hospital, and this could imply less serious acute conditions, but the mortality has only scarcely been studied. The aim of this study was to examine the most frequent sub-diagnoses among patients with hospital non-specific diagnoses after calling 112 and their subsequent mortality. METHODS: A historical cohort study of patients brought to the hospital by ambulance after calling 112 in 2007-2014 and diagnosed with a non-specific diagnosis, chapter R or Z, in the International Classification of Diseases, 10th edition (ICD-10). 1-day and 30-day mortality was analyzed by survival analyses and compared by the log-rank test. RESULTS: We included 74,847 ambulance runs in 53,937 unique individuals. The most frequent diagnoses were 'unspecified disease' (Z039), constituting 47.0% (n 35,279). In children 0-9 years old, 'febrile convulsions' was the most frequent non-specific diagnosis used in 54.3% (n 1602). Overall, 1- and 30-day mortality was 2.2% (n 1205) and 6.0% (n 3258). The highest mortality was in the diagnostic group 'suspected cardiovascular disease' (Z035) and 'unspecified disease' (Z039) with 1-day mortality 2.6% (n 43) and 2.4% (n 589), and 30 day mortality of 6.32% (n 104) and 8.1% (n 1975). CONCLUSION: Among patients calling an ambulance and discharged with non-specific diagnoses the 1- and 30-day mortality, despite modest mortality percentages lead to a high number of deaths.

BACKGROUND & AIMS: Food addiction (FA) is likely to contribute to the global obesity epidemic. Most studies of FA have been conducted within clinical and/or highly selected populations, suggesting that prevalence estimates of FA may be biased. This is problematic as valid estimates of the population prevalence of FA is a requirement for informing and designing public health initiatives focusing on this phenotype. Therefore, we aimed to estimate the weighted prevalence of food addiction in the adult general population of Denmark. METHODS: A random sample of 5000 individuals aged 18 to 62 from the Danish population was invited to participate in a survey, which included the Yale Food Addiction Scale (YFAS 2.0) and several rating scales measuring eating pathology and other psychopathology. Health, demographic and socioeconomic data from the Danish registers were linked to all invitees to allow for attrition analysis. The analysis had three steps: I) Psychometric validation of the Danish version of YFAS 2.0 II) Attrition analysis to examine selection bias, and III) Estimation of the weighted prevalence of FA taking attrition into account. RESULTS: The confirmatory factor analysis of the YFAS 2.0 supported a one-factor model, and the scale had good internal consistency. The YFAS 2.0 score correlated with eating pathology including binge eating frequency, impulsivity and body mass index (BMI). The survey response rate was 34.0% (n = 1699) with a slight overrepresentation of respondents with higher socioeconomic status. The crude prevalence of FA was 9.0%. When taking attrition into account, the weighted prevalence of FA was 9.4% CI 95% [7.9-10.9]. CONCLUSIONS: The psychometric properties of the Danish version of the YFAS 2.0 were good. The weighted prevalence of FA was very similar to the crude prevalence estimate. This suggests that attrition may not be a large problem when estimating the prevalence of FA with the YFAS 2.0.

BACKGROUND: Emergency departments handle a large proportion of acute patients. In 2007, it was recommended centralizing the Danish healthcare system and establishing emergency departments as the main common entrance for emergency patients. Since this reorganization, few studies describing the emergency patient population in this new setting have been carried out and none describing diagnoses and mortality. Hence, we aimed to investigate diagnoses and 1- and 30-day mortality of patients in the emergency departments in the North Denmark Region during 2014-2016. METHODS: Population-based historic cohort study in the North Denmark Region (580,000 inhabitants) of patients with contact to emergency departments during 2014-2016. The study included patients who were referred by general practitioners (daytime and out-of-hours), by emergency medical services or who were self-referred. Primary diagnoses (ICD-10) were retrieved from the regional Patient Administrative System. For non-specific diagnoses (ICD-10 chapter 'Symptoms and signs' and 'Other factors'), we searched the same hospital stay for a specific diagnosis and used this, if one was given. We performed descriptive analysis reporting distribution and frequency of diagnoses. Moreover, 1- and 30-day mortality rate estimates were performed using the Kaplan-Meier estimator. RESULTS: We included 290,590 patient contacts corresponding to 166 ED visits per 1000 inhabitants per year. The three most frequent ICD-10 chapters used were 'Injuries and poisoning' (38.3% n = 111,274), 'Symptoms and signs' (16.1% n = 46,852) and 'Other factors' (14.52% n = 42,195). Mortality at day 30 (95% confidence intervals) for these chapters were 0.86% (0.81-0.92), 3.95% (3.78-4.13) and 2.84% (2.69-3.00), respectively. The highest 30-day mortality were within chapters 'Neoplasms' (14.22% (12.07-16.72)), 'Endocrine diseases' (8.95% (8.21-9.75)) and 'Respiratory diseases' (8.44% (8.02-8.88)). CONCLUSIONS: Patients in contact with the emergency department receive a wide range of diagnoses within all chapters of ICD-10, and one third of the diagnoses given are non-specific. Within the non-specific chapters, we found a 30-day mortality, surpassing several of the more organ specific ICD-10 chapters. TRIAL REGISTRATION: Observational study - no trial registration was performed.
