Aim: To investigate the prevalence of attention‐deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in a population‐based birth cohort and correlate the findings with prenatal and perinatal factors. We hypothesized that children born preterm, having experienced preeclampsia or maternal overweight, would have an increased risk of ADHD or ASD. Method: A Swedish cohort of 2666 children (1350 males, 1316 females) has been followed from birth with parental and perinatal data. The National Board of Health and Welfare's registries were used to collect data regarding perinatal status and assigned diagnoses at the age of 12 years. Results: The prevalence of ADHD and ASD was 7.6% and 1.1% respectively. Maternal obesity early in pregnancy resulted in a three‐fold increased risk of ADHD in the child. Similarly, paternal obesity resulted in a two‐fold increased risk. The association was significant also when adjusted for sex, preterm birth, smoking, and lower educational level. The prevalence of ASD was too low for statistically relevant risk factor analyses. Interpretation: Our results corroborate earlier findings regarding prevalence and sex ratio for both ADHD and ASD. Maternal body mass index and preterm birth were correlated with an ADHD diagnosis at the age of 12 years. [ABSTRACT FROM AUTHOR]

Aim: Treatment of childhood obesity is often insufficient and may be aggravated by high co‐occurrence of attention‐deficit/hyperactivity disorder (ADHD). We aimed to investigate whether children with overweight or obesity normalised in weight when receiving stimulant treatment for ADHD. Methods: Growth data of 118 children were obtained from medical records at outpatient paediatric and children's psychiatric services in the Gothenburg area, Sweden. The children were diagnosed with ADHD and were between 6 and 17 years at the start of stimulant treatment. The pre‐treatment data act as an internal control where every child is their own control. Results: At the start of treatment, 74 children had normal weight and 44 had either overweight or obesity. During the year with stimulants, the mean (SD) body mass index (BMI) in standard deviation score (SDS) decreased significantly: −0.72 (0.66) compared with 0.17 (0.43) during the year before treatment (p < 0.01). After one year with treatment, 43% of those with overweight or obesity had reached normal weight. Conclusions: Stimulant treatment for ADHD yields significant weight loss. In children with overweight or obesity and ADHD, this is an important finding showing additional benefit in terms of weight management. [ABSTRACT FROM AUTHOR]

Objective: To examine Facial Emotion Recognition (FER) and visual scanning behavior (eye‐tracking) during FER in women long‐term recovered from teenage‐onset anorexia nervosa (recAN) with and without autism spectrum disorder (±ASD) and age‐matched comparison women (COMP), using a sensitive design with facial emotion expressions at varying intensities in order to approximate real social contexts. Method: Fifty‐seven 38–47‐year‐old women (26 recAN of whom six with ASD, 31 COMP) participated in the study. They completed a non‐verbal FER task, consisting of matching basic emotions at different levels of expression intensity with full emotional expressions. Accuracy, response time and visual scanning behavior were measured. Results: There were no differences between recAN‐ASD and COMP in FER accuracy and visual scanning behavior during FER, including eye viewing and hyperscanning. In an exploratory analysis, recAN+ASD were more accurate than recAN‐ASD in identifying expressions at low intensity, but not at medium or high expression intensity. Accuracy was not associated with the extent of attention to the eye region. Discussion: Our data indicate that women long‐term recovered from adolescent‐onset AN do not have deficits in basic FER ability and visual scanning behavior during FER. However, the presence of comorbid ASD might affect face processing in recovered AN. Future studies investigating basic FER in acute and recovered AN and other conditions need to ensure that the stimuli used are sensitive enough to detect potential deficits. [ABSTRACT FROM AUTHOR]

Objective A finding consistent with the transdiagnostic approach to eating disorders is that about half of those with restricting anorexia nervosa (AN) eventually undergo a transition to the binge/purge (BP) subtype or to bulimia nervosa. Given evidence that individuals with bulimic symptoms exhibit elevated weights premorbidly, we tested the hypothesis that among those with AN, highest premorbid BMI would predict which individuals with AN would develop AN-BP. Method The current study used longitudinal data from a community sample of adolescents with AN in Sweden. Premorbid weights were obtained from growth charts, and participants were re-assessed at 6, 10, and 18 years after first presentation with AN. Results A greater highest premorbid BMI z score predicted a greater likelihood of developing binge/purge symptoms over 18 years. Discussion Among individuals who develop an eating disorder, premorbid BMI may be implicated in the type and course of the eating disorder that emerges. [ABSTRACT FROM AUTHOR]

Objective: To investigate prevalence of neurodevelopmental disorders in children with obesity and to compare body mass index (BMI) and metabolic profile in the children.Methods: Seventy-six children (37 girls, 39 boys) were consecutively recruited from a university outpatient clinic specialized in severe obesity. Neurodevelopmental disorders including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and developmental coordination disorder (DCD) were assessed using interviews and questionnaires. Neurodevelopmental diagnoses were collected retrospectively in medical records.Results: BMI ranged between 1.9 and 5.9 SDS and age between 5.1 and 16.5 years. In 13.2% and 18.4% ASD and ADHD was assigned, respectively. In addition, 25% screened positive for DCD, 31.6% had at least one neurodevelopmental disorder, and 18.4% had a parent who screened positive for adult ADHD. Girls with ASD/ADHD had higher BMI SDS than girls without neurodevelopmental disorder (P = 0.006).Conclusions: One third of children with obesity referred to specialist centers have a neurodevelopmental disorder including deviant motor skills, and these problems may deteriorate weight status. One fifth of the parents exhibit ADHD symptomatology which could partly explain the poor adherence by some families in obesity units. Future obesity therapy could benefit from incorporating a neurodevelopmental treatment approach. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Although weight history is relevant in predicting eating disorder symptom severity, little is known about its role in the etiology of anorexia nervosa (AN). This study aimed to determine whether BMI or BMI trajectory differed between individuals who later developed adolescent-onset AN and a comparison group of HCs between school grades 1 through 6. Method This study was based on longitudinal data that identified 51 adolescents with AN and 51 matched HCs. Cases were identified through community screening in Sweden and included individuals born in 1969 through 1977. Measured weights and heights were retrieved and BMIs and weight trajectories of the AN and HC groups were compared using growth curve analysis. Main outcome measures included measured BMI and BMI trajectories from grades 1-6. Secondary outcomes examined included ponderal index at birth and maternal body weight. Results Individuals who later developed AN had higher BMIs than HCs between grades 1 and 6, by an average of 1.42 BMI-units. There was no difference in rate of weight gain between groups. Ponderal index at birth was higher for the AN as compared with HC group. Maternal weight did not differ significantly between groups. Discussion These findings, combined with those previously reported on the premorbid BMIs of those with bulimia nervosa, suggest that a predisposition toward elevated premorbid BMIs during childhood characterizes those who later develop anorexia or bulimia nervosa. These findings are consistent with a transdiagnostic perspective and suggest shared risk factors for AN and obesity. © 2016 Wiley Periodicals, Inc.

Aims To investigate cognitive abilities and adaptive skills in children and adolescents with myotonic dystrophy type 1 (DM1) and correlate the findings to the cytosine-thymine-guanine (CTG) repeat expansion size. Method Cognitive level was assessed in 55 children and adolescents with DM1 (31 males, 24 females; mean age 12y 1mo, SD 5y 1mo; range 2y 7mo–21y 5mo) divided into the following categories: severe congenital DM1 ( n=19), mild congenital DM1 ( n=18), and childhood DM1 ( n=18). The Griffiths Mental Developmental Scale, the Wechsler Scales, and the Vineland Adaptive Behavior Scales (VABS) for adaptive skills were used for this purpose. Results Learning disability was found in 95% of the severe congenital group, 83% of the mild congenital group, and 89% of the childhood DM1 group. The more severe the form of DM1, the lower the full-scale IQ (FSIQ; rs=0.28, p=0.044). The individuals with severe congenital and childhood DM1 had a significantly higher verbal IQ than performance IQ (severe congenital: mean difference 5.7, SD 5.7, p=0.008; childhood DM1: mean difference 9.8, SD 18.0, p=0.038). CTG repeat expansion correlated negatively with FSIQ ( rs=−0.63, p<0.006). Almost all participants showed poor results on the VABS. There was a positive relationship between cognitive level and adaptive skills in the mild congenital ( rs=0.95, p<0.01) and childhood DM1 groups ( rs=0.92, p<0.01). Interpretation Children and adolescents with DM1 exhibit significant cognitive and adaptive problems. [ABSTRACT FROM AUTHOR]

Objective: To study reproduction in a representative group of anorexia nervosa (AN) cases. Method: Fifty-one adolescent-onset AN cases (48 women; three men), originally recruited after community screening, and 51 matched comparison cases (COMP) were interviewed 18 years after AN onset at a mean age of 32 years, regarding pregnancies and early development of the children. Results: The results of the 48 AN and 48 COMP group women are reported in the present study. Six women still had an eating disorder (ED), none of whom had become a mother. Twenty-seven women in the AN group and 31 women in the COMP group had children. Three women had an ED during pregnancy. Mean age at birth of the first child was lower in the AN group. Five AN women reported postpartum depression. Children in the AN group had significantly lower birth weight than the children in the COMP group. No other complications during pregnancy and the neonatal period differed across groups. Feeding difficulties were not overrepresented among the children of the AN group. Discussion: Adults who had recovered from teenage-onset AN did not differ in most aspects from matched controls with respect to pregnancies and development of their offspring. © 2009 by Wiley Periodicals, Inc.

Objective To follow up bone mineral density (BMD) 4 years after decreased BMD was diagnosed in adult individuals with teenage-onset anorexia nervosa (AN). Method In a previous study BMD was assessed in 39 individuals (36 women, 3 men) 11 years after AN onset. Decreased BMD occurred in a minority. In the present study, a 4-year follow-up of individuals with decreased BMD, 11 AN women were reassessed by using dual energy X-ray absorptiometry (DXA). Two women still had an eating disorder (ED). Results Eight out of eleven women met criteria for decreased BMD/osteoporosis. There was an increase in BMD of total body and lumbar spine (LS). There was a relationship between lumbar BMD and BMI. Conclusion At follow-up of decreased BMD in adult women with teenage-onset of AN, there is a possibility of improvement of BMD. © 2007 John Wiley & Sons, Ltd and Eating Disorders Association.

Objective We studied fertility and history of child sexual abuse (CSA) in a representative group of anorexia nervosa (AN) cases. Method Fifty-one adolescent-onset AN cases recruited after community screening and 51 matched comparison cases were interviewed 10 years after reported AN onset, at mean age 24 years, regarding children, miscarriages, and fertility problems. They completed anonymously the Finkelhor self-report questionnaire regarding history of CSA. Results There were few fertility problems in our AN population. There was a tendency towards more subjects in the AN group to give birth to a child (10 AN and 4 comparison mothers). The prevalence of CSA was equal between groups. For example, 6% in each group had experienced CSA before the age of 10 years, and 14% of the AN and 12% of the comparison cases reported CSA. Discussion Infertility and history of CSA may not be overrepresented in a population-based AN sample at long-term follow-up. © 2005 by Wiley Periodicals, Inc. [ABSTRACT FROM AUTHOR]

Deals with a study which evaluated bone mineral density and body composition 11 years after the onset of anorexia nervosa. Methods; Results; Discussion.

The aim of this study was to assess prospectively the long-term outcome in a representative sample of teenage-onset anorexia nervosa (AN) in respect of psychiatric disorders and overall outcome. Fifty-one AN cases, recruited by community screening, with a mean age of onset of 14 years, was contrasted with 51 matched comparison cases at a mean age of 24 years (10 years after AN onset). All 102 cases had been examined at ages 16 and 21 years. At 24 years all probands were interviewed regarding psychiatric disorders (SCID-I) and overall outcome (Morgan-Russell assessment schedule, the GAF). There were no deaths at 10-year follow-up. One in four in the AN group had a persisting eating disorder (ED), including three who still had anorexia nervosa. Lifetime diagnoses of affective disorders and obsessive-compulsive disorder were over-represented in the AN group. Outcome according to Morgan-Russell was poor in 27%, intermediate in 29%, and good in 43%. According to the GAF, half the AN group had a poor psychosocial functioning. These were subjects with either a persisting ED or lifelong problems with social interaction or obsessive-compulsive behaviour. Ten-year outcome of teenage-onset AN is favourable in the majority of cases; most individuals have recovered from their ED and have no other axis I disorder. However, half the AN group reported poor psychosocial outcome, in most cases explained by a persisting ED or chronic obsessive-compulsive behaviour/social interaction problems.

The article discusses the importance of Attention-deficit hyperactivity disorder (ADHD) in children and adolescents with obesity. It mentions that the quality of parent-child attachment and interaction are important in children growth and development. It examines the possible risks of ADHD in obese children and adults. It also highlights the possible environmental risks in children with deficient parental attachment .

Myotonic dystrophy type 1 (DM1) is an autosomal dominant disorder, caused by an expansion of a CTG triplet repeat in the DMPK gene. The aims of the present study were to classify a cohort of children with DM1, to describe their neuropsychiatric problems and cognitive level, to estimate the size of the CTG expansion, and to correlate the molecular findings with the neuropsychiatric problems. Fifty-seven children and adolescents (26 females; 31 males) with DM1 (CTG repeats > 40) were included in the study. The following instruments were used: Autism Diagnostic Interview-Revised (ADI-R), 5-15, Griffiths Mental Development Scales, and the Wechsler Scales. Based on age at onset and presenting symptoms, the children were divided into four DM1 groups; severe congenital (n = 19), mild congenital (n = 18), childhood (n = 18), and classical DM1 (n = 2). Forty-nine percent had an autism spectrum disorder (ASD) and autistic disorder was the most common diagnosis present in 35% of the subjects. Eighty-six percent of the individuals with DM1 had mental retardation (MR), most of them moderate or severe MR. ASD was significantly correlated with the DM1 form; the more severe the form of DM1, the higher the frequency of ASD. The frequency of ASD increased with increasing CTG repeat expansions. ASD and/or other neuropsychiatric disorders such as attention deficit hyperactivity disorder, and Tourette's disorder were found in 54% of the total DM1 group. In conclusion, awareness of ASD comorbidity in DM1 is essential. Further studies are warranted to elucidate the molecular etiology causing neurodevelopmental symptoms such as ASD and MR in DM1., (2008 Wiley-Liss, Inc.)
