Abstract
AIM The aim was to assess the rate and overlap of language and other neurodevelopmental problems in children aged 9-12 years with unilateral or mild to moderate bilateral sensorineural hearing loss. METHODS Caregivers of 24 of the 58 eligible children, born 2004-2007, registered at the regional audiology department in Gothenburg, Sweden, with these types of hearing loss completed the Five-to-Fifteen questionnaire, a comprehensive screening instrument for neurodevelopmental problems. Of these 24 children, 21 were assessed with the Clinical Evaluation of Language Fundamentals-Fourth Edition (CELF-4). Children with scores indicating definite problem on the Five-to-Fifteen questionnaire and their parents were invited to a clinical neuropaediatric assessment. RESULTS Of the 24 children, 13 (54%) screened positive for definite neurodevelopmental problems. Clinical assessments confirmed the presence of at least one neurodevelopmental disorder in eight of these 24, corresponding to 33%. Seven (33%) of the 21 children participating in the CELF-4 had scores indicating a language disorder, of whom four children had a neurodevelopmental disorder according to the neuropaediatric assessment. CONCLUSION The results support that schoolchildren with unilateral or mild to moderate bilateral sensorineural hearing loss should undergo neurodevelopmental screening to identify possible coexisting neurodevelopmental problems or disorders.

Abstract
Recent research has suggested that temporal sequencing of narrative events might be a domain-general ability that underlies oral narrative capacities. The current study investigated this issue in a group of children with known pragmatic and narrative difficulties, namely Autism Spectrum Disorder (ASD). We hypothesized (1) that children with ASD (n = 45) would retell narratives of poorer quality than both chronological age-matched (CAM) children and younger children matched on sentence-level language skills (LM), and (2) that nonverbal temporal sequencing skills would uniquely predict individual differences in oral narrative performance in children with ASD. The results show that children with ASD performed poorer on all measures of oral narrative quality compared with the CAM group, and on eight of ten measures compared with the LM group. Thus, our first hypothesis was confirmed, suggesting that narrative difficulties in ASD cannot be fully explained by impaired language. The second hypothesis was only partly confirmed: nonverbal temporal sequencing explained significant or marginally significant variance in some, but not all, aspects of oral narrative performance of children with ASD. These results are discussed from theoretical and clinical/educational perspectives, in relation to the heterogeneity of language skills in ASD and to domain-general features of narrative processing.

Abstract
AIM To analyse cognitive functioning in 4-5-year-old children who had experienced febrile seizures (FS) and to assess the importance of complex, recurrent and early vs late onset FS. METHODS The sample consisted of 73 children, screen positive for FS, drawn from the general child population of 4-year-old children attending their health check-up at child healthcare centres in Gothenburg, Sweden. They were assessed as regards general cognitive ability, visual memory and attention and were contrasted with age norms and with results obtained in 20 children without FS from the same healthcare centres. RESULTS Of the 73 children, two had a previously diagnosed intellectual disability (ID) (one mild, one moderate) and two further children tested within the study had results corresponding to mild ID. Children with early onset of FS (before age 12 months)-who often had recurrent FS-had lower full-scale, verbal and processing speed IQ than those who had later onset of FS. CONCLUSION Children with early onset of FS and particularly those with recurrent FS may be at increased risk for poorer verbal and processing speed functioning and therefore at risk of developing cognitive, executive dysfunctions. They would probably benefit from neuropaediatric and neuropsychological follow-up.

Abstract
AIM Our aim was to extend the validity of a questionnaire developed for screening and identifying early symptomatic syndromes eliciting neurodevelopmental clinical examinations-questionnaire (ESSENCE-Q) in young children. METHODS Early symptomatic syndromes eliciting neurodevelopmental clinical examinations-questionnaire data for 207 children, living in Aki City, Japan, in 2014-2015, were obtained from mothers, public health nurses and psychologists at 20- and 40-month routine check-ups at child healthcare centres. These were checked against subsequent ESSENCE diagnoses made by physicians. Receiver operating characteristic curves were constructed, and the area under the curves was compared. Sensitivity, specificity, positive predictive values (PPVs) and negative predictive values were calculated at optimal cut-off values. The clinical utility index was also calculated. RESULTS When the ESSENCE-Q was used by public health nurses, it demonstrated good validity, in terms of high sensitivity and high NPVs, at the 20-month check-up, but not at 40 months. Psychologists demonstrated good validity at both ages, but mothers did not. Good negative utility indexes, indicating screening accuracy, were obtained from the psychologists at both check-ups and from nurses at 20 months. CONCLUSION The ESSENCE-Q results used by nurses and psychologists showed good validity. Future studies should confirm the effectiveness of this tool to identify children in need of clinical detailed neurodevelopmental assessment.

Abstract
We integrate recent findings from neuro-anatomy, electroencephalography, quantum biology and social/neurodevelopment to propose that the brain surface might be specialised for communication with other brains.
Ground breaking, but still small-scale, research has demonstrated that human brains can act in synchrony and detect the brain activity of other human brains. Group aggregation, in all species, maximises community support and safety but does not depend on verbal or visual interaction. The morphology of the brain’s outermost layers, across a wide range of species, exhibits a highly folded fractal structure that is likely to maximise exchange at the surface: in humans, a reduced brain surface area is associated with disorders of social communication. The brain sits in a vulnerable exposed location where it is prone to damage, rather than being housed in a central location such as within the ribcage.
These observations have led us to the hypothesis that the brain surface might be specialised for interacting with other brains at its surface, allowing synchronous non-verbal interaction. To our knowledge, this has not previously been proposed or investigated.

Abstract
BACKGROUND Little is known about the long-term outcome of anorexia nervosa. AIMS To study the 30-year outcome of adolescent-onset anorexia nervosa. METHOD All 4291 individuals born in 1970 and attending eighth grade in 1985 in Gothenburg, Sweden were screened for anorexia nervosa. A total of 24 individuals (age cohort for anorexia nervosa) were pooled with 27 individuals with anorexia nervosa (identified through community screening) who were born in 1969 and 1971-1974. The 51 individuals with anorexia nervosa and 51 school- and gender-matched controls were followed prospectively and examined at mean ages of 16, 21, 24, 32 and 44. Psychiatric disorders, health-related quality of life and general outcome were assessed. RESULTS At the 30-year follow-up 96% of participants agreed to participate. There was no mortality. Of the participants, 19% had an eating disorder diagnosis (6% anorexia nervosa, 2% binge-eating disorder, 11% other specified feeding or eating disorder); 38% had other psychiatric diagnoses; and 64% had full eating disorder symptom recovery, i.e. free of all eating disorder criteria for 6 consecutive months. During the elapsed 30 years, participants had an eating disorder for 10 years, on average, and 23% did not receive psychiatric treatment. Good outcome was predicted by later age at onset among individuals with adolescent-onset anorexia nervosa and premorbid perfectionism. CONCLUSIONS This long-term follow-up study reflects the course of adolescent-onset anorexia nervosa and has shown a favourable outcome regarding mortality and full symptom recovery. However, one in five had a chronic eating disorder.

Abstract
Borderline intellectual functioning (BIF), that is to say, tested IQ levels in the range of 70-84/85, is prevalent, affecting about 12%-14% of the population depending on the exact level for "diagnostic" cutoff. In the current Diagnostic and Statistical Manual of Mental Disorders, BIF does not have a separate diagnostic category but can be categorized with a V-code. Children and adolescents with BIF usually struggle both as regards school performance and in respect of social functioning. BIF is common in attention deficit hyperactivity disorder, but sometimes attention problems in schoolchildren with BIF may be a consequence of nonadapted academic demands. Autism and BIF may also coexist, and there are many cases of so-called high-functioning autism who are high functioning only in the sense that they do not meet criteria for intellectual disability, but function in the area of BIF. Currently, too little attention is given to the negative effects of BIF on child development and adaptation. Learning, academic, and behavioral problems and grade retention may be markers of BIF. Our diagnostic and classification manuals need to have specific categories that clarify the problems that BIF entails so that affected individuals can avail themselves of better educational support and understanding.

Abstract
OBJECTIVE Rating scales and neuropsychological tests including continuous performance tests (CPTs) are widely used to assess executive functions (EFs). Event-related potentials (ERPs) are also used to index certain EFs such as action preparation and inhibition. In this descriptive study, we examined the associations between results on an EF rating scale, a CPT and ERP components in ADHD as a function of age. METHODS Fifty-nine patients with ADHD (and more often than not with comorbid disorders) in two age groups (9-12 years and 13-17 years) were assessed using EF ratings, a visual CPT and ERPs (CueP3, P3go and P3no-go). RESULTS There were age related changes in the ERPs with the CueP3 amplitude being stronger in children, and the P3no-go amplitude stronger in adolescents. The associations between the EF measures were different in the two age groups. In particular, the P3no-go seemed to reflect different EF-related processes in children versus adolescents. CONCLUSION Age group effects were seen on a selection of ERP amplitudes in this sample of patients with ADHD. Ratings, test scores and EF-related ERPs seem to capture different aspects of EF in ADHD, and the associations differed depending on age group. The results show that different measures of EF are not interchangeable and highlight the importance of age when interpreting ERPs.

Abstract
Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are more common in children with cerebral palsy (CP) than in the general population, but may still be underdiagnosed. This study aimed to estimate screen-positive ASD and ADHD in a population-based group of 264 school-aged children with CP born 1999-2006 from the CP register of western Sweden. Validated parent-completed questionnaires were used at a median age of 12 years 11 months (range 8-17 years). Three different scales were used to detect signs of ASD and ADHD, respectively. Response rate was 88% (232/264). In 19 children, all in the most disabled group, the screening procedure was not feasible due to too few questionnaire items completed, leaving 213 for analyses. One third (74/213) of the children screened positive for ASD and half of the children (106/213) for ADHD, which was about twice as often as ASD/ADHD diagnoses had been clinically identified. Children with intellectual disability, epilepsy and/or impaired speech ability more often screened positive for ASD as well as ADHD. Severe motor impairment was more frequently associated with screen-positive ASD, but not ADHD. Neither sex nor CP type was associated with screen-positive ASD/ADHD. In conclusion, school-aged children with CP very often screened positive for ASD and/or ADHD. The prevalence of ASD and ADHD is most likely underestimated in children with CP. These screening findings require further investigations.

Abstract
Autism spectrum disorder (ASD) is diagnosed more often in boys than girls. Here, we compared the degree of autism - and related disorders - symptomatology in boys and girls with a registered diagnosis of ASD. We used parent telephone interview A-TAC (Autism-Tics, ADHD and other Comorbidities) ratings of 30,392 twins aged 9 or 12 (including 308 boys and 122 girls with National Patient Register diagnoses of ASD) participating in the Child and Adolescent Twin Study in Sweden. We used z-scores for ASD-symptoms, standardized separately for boys and girls. Boys with a diagnosis of ASD had a higher raw mean score than girls with a diagnosis on the A-TAC ASD domain. However, utilizing the z-scores, girls with a diagnosis of ASD deviated further away from the female population mean than did the boys with ASD from the male population mean. Girls also had higher standardized mean values for symptoms of Attention-Deficit/Hyperactivity Disorder, Learning Disabilities and Oppositional Defiant Disorder. The findings suggest that girls diagnosed with autism may represent an even more extreme end of the female population autistic features distribution, than diagnosed boys from the male population autistic features distribution. Future studies may benefit from examining the use of sex-specific cut-off scores.

Abstract
BACKGROUND Anxiety disorders in adolescence have been associated with several psychiatric outcomes. We sought to describe the prospective relationship between various levels of adolescent anxiety and psychiatric diagnoses (anxiety-, bipolar/psychotic-, depressive-, and alcohol and drug misuse disorders) and suicidal ideation in early adulthood while adjusting for childhood attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and developmental coordination disorder (DCD). Furthermore, we aimed to estimate the proportion attributable to the various anxiety levels for the outcomes. METHODS We used a nation-wide population-based Swedish twin study comprising 14,106 fifteen-year-old twins born in Sweden between 1994 and 2002 and a replication sample consisting of 9211 Dutch twins, born between 1985 and 1999. Adolescent anxiety was measured with parental and self-report. Psychiatric diagnoses and suicidal ideation were retrieved from the Swedish National Patient Register and via self-report. RESULTS Adolescent anxiety, of various levels, predicted, in the Swedish National Patient Register, anxiety disorders: hazard ratio (HR) = 4.92 (CI 3.33-7.28); depressive disorders: HR = 4.79 (3.23-7.08), and any psychiatric outcome: HR = 3.40 (2.58-4.48), when adjusting for ADHD, ASD, and DCD. The results were replicated in the Dutch data. The proportion of psychiatric outcome attributable to adolescent anxiety over time (age 15-21) was 29% for any psychiatric outcome, 43-40% for anxiety disorders, and 39-38% for depressive disorders. CONCLUSION Anxiety in adolescence constitutes an important risk factor in the development of psychiatric outcomes, revealing unique predictions for the different levels of anxiety, and beyond the risk conferred by childhood ADHD, ASD, and DCD. Developmental trajectories leading into psychiatric outcomes should further empirically investigated.

Abstract
BACKGROUND Brief screening instruments focusing on autism spectrum disorder (ASD) that can be administered in primary care are scarce; there is a need for shorter and more precise instruments. The Autism-Tics, AD/HD and other Comorbidities inventory (A-TAC) has previously been validated for ASD reporting excellent validity. This study aims to determine the psychometric properties of each item in the ASD domain (17 items) in the A-TAC using item response theory (IRT), and thereby construct and validate a short form that could be used as a screening instrument in the general population. METHODS Since 2004, parents of all 9-year-old Swedish twins have been invited to participate in a telephone interview in the Child and Adolescent Twin Study in Sweden (CATSS). The CATSS is linked to the National Patient Register (NPR), which includes data from in- and outpatient care. Data on ASD (A-TAC) collected in CATSS were compared with diagnoses from the NPR. Diagnoses that had been made both before (previous validity) and after (predictive validity) the interviews were included. The sample was divided into a developmental sample and a validation sample. An IRT model was fitted to the developmental sample and item parameters were used to select a subset of items for the short form. The performance of the proposed short form was examined in the validation sample by the use of receiver operation characteristic curves. RESULTS Four items which were able to discriminate among individuals with more autism traits were deemed sufficient for use in the short form. The values of the area under the receiver operating characteristic curve for a clinical diagnosis of ASD was .95 (previous validity) and .72 (predictive validity). CONCLUSIONS The proposed short form with 4 out of the original 17 items from A-TAC, showed excellent previous validity while the predictive validity was fair. The validity of the short form was in agreement with previous validations of the full ASD domain. The short form can be a valuable screening instrument in primary care settings in order to identify individuals in need for further assessment and for use in epidemiological studies.

Abstract
AIM To describe motor function and associated impairments, particularly autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), in school-aged children with cerebral palsy (CP). METHODS Population-based study of all children with CP born 1999-2006 from the county of Västra Götaland, Sweden; 264 children (141 males, 123 females). Information was obtained from the CP Register of western Sweden (data collected at 4-8 years of age) and all medical records at 10-17 years of age. RESULTS Cerebral palsy was spastic in 76%, dyskinetic in 17% and ataxic in 7% of all children. Sixty-three per cent were independent walkers. Associated impairments were present in 75%. Vision was impaired in 19%, hearing in 8% and speech in 54%. Intellectual disability (ID) was present in 53% and epilepsy in 41%. ID had increased from 42% to 53% since preschool-age. Neuropsychiatric impairments were present in 32% of the children; ASD in 18%; and ADHD in 21%. All impairments, except for ASD and ADHD, increased with more severe motor impairment. CONCLUSION Three in four school-aged children with CP have associated impairments, underscoring the need to broadly assess every child. The high rate of ASD and ADHD points to the importance of in-depth studies of such impairments in CP.

Abstract
Purpose To investigate the prevalence of chronic pain and its association with health-related quality of life (HRQoL) in a group of women, diagnosed with autism spectrum disorder (ASD) and/or attention deficit hyperactive disorder (ADHD) in childhood. Patients and methods Prospective longitudinal 16–19 years follow-up study of 100 Swedish females diagnosed with ASD and/or ADHD in childhood/adolescence. Seventy-seven of the women were included in the current sub-study, using validated measures of pain perception and quality of life. Results A large majority of the women (76.6%) reported chronic pain. HRQoL was low overall and lower still for those reporting chronic pain. Women with ADHD who had ongoing treatment with stimulants reported a significant lower prevalence of chronic widespread pain (CWP) than those not treated. Conclusion Comorbidity with chronic pain is common in women with ASD and/or ADHD and important to address in the clinic since it is associated with an already low HRQoL. Treatment for ADHD might reduce the pain in some cases.

Abstract
Autism spectrum disorders (ASD) comprises heterogeneous neurodevelopmental conditions with symptom onset usually during infancy. However, about 10%-30% of affected cases experience a loss of language and social skills around 18-30 months, so-called regressive autism. In this subset with regression, immune dysfunctions including inflammation and autoimmunity have been proposed to be at risk factors. Given the implication of the human histocompatibility antigens (HLA) system in various aspects of immune responses, including autoimmunity, and in ASD, we investigate here the distribution of the HLA Class I and Class II haplotypes in 131 children with ASD meeting DSM-IV TR criteria, with and without regression. We found that 62 of the 98 non-regressive ASD patients carry the HLA-DPA1*01-DPB1*04 sub-haplotype as compared to 14 of the 33 patients with regression (63% vs. 43% respectively, Pc = 0.02), suggesting that this HLA haplotype may exert a protective effect against regression. Similarly, the HLA-DPA1*01-DPB1*04 has also been found to be more represented in healthy controls as compared to patients affected with common nonpsychiatric autoimmune disorders. Overall our findings suggest a possible involvement of HLA polymorphism in the context of regressive ASD. Autism Res 2020, 13: 182-186. © 2019 The Authors. Autism Research published by International Society for Autism Research published by Wiley Periodicals, Inc. LAY SUMMARY: Immune dysfunctions including inflammatory and autoimmune processes have been reported in autism, particularly in regressive forms. In this study, we analyzed the distribution of HLA haplotypes among children with autism spectrum disorder (ASD), with and without regression from Sweden and observed that HLA-DPA1*01-DPB1*04 sub-haplotype was less represented in patients with regressive autism as compared with those without regression. Such possible protective effect, also observed in other common autoimmune disorders, may constitute a link between HLA-mediated immune processes and regressive ASD.

Abstract
In a Swedish sample of persons eligible for disability services and aged 55 years or older in 2012, persons (n = 601) with autism spectrum disorder diagnoses registered in specialist care were identified. Register data concerning diagnoses of other psychiatric disorders, psychiatric care, and psychiatric medication were reviewed. More than 60% had been in contact with psychiatric care. The majority had no intellectual disability (ID) diagnosis recorded during the study period. Apart from ID, affective disorders, anxiety and psychotic disorders were most commonly registered; alcohol/substance abuse disorders were uncommon. Psychotropic drug prescriptions were very common, especially in the ID group. Professionals need awareness of this vulnerable group; studies concerning their life circumstances and service requirements should be conducted.

Autism, ADHD and parent-reported behavioural difficulties in young children with epilepsy. Seizure 2019; 71:233-239.

Abstract
PURPOSE To provide data on the prevalence of Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), and parent reported behaviour difficulties in young children with epilepsy, and to compare results with children with neurodisability (neurodevelopmental/neurological difficulties) without epilepsy. METHOD Children with epilepsy (1-7 years, n = 48) and children with neurodisability (1-7 years, n = 48) matched for gender, chronological and developmental age underwent psychological assessment. Parents completed measures of behaviour including the Strengths and Difficulties Questionnaire (SDQ). DSM-5 diagnoses of ASD and ADHD were made at consensus case conferences. Factors associated with child behaviour were analysed using linear regression. RESULTS Of the children with epilepsy, 18% met ASD criteria and 40% met ADHD criteria (corresponding figures in the non-epilepsy group were 41% and 27%). A large proportion (76%-78%) in both groups scored in the at-risk range on the SDQ and frequently had difficulties across multiple behavioural domains. Children with epilepsy had more concerns expressed regarding attention and mood. None of the epilepsy factors were significantly associated with scores on the behavioural measures. SIGNIFICANCE Young children with epilepsy had a very high level of parent reported behavioural difficulties and a high risk for ADHD and ASD highlighting the need for comprehensive multidisciplinary assessment. Behavioural concerns were not greater than for other children with non-epilepsy related neurodisability with the exception of attention and mood. Epilepsy related factors were not associated with child behaviour, suggesting that seizures per se do not confer a unique risk for behavioural difficulties.

Abstract
Two community-based cohorts of children with autism spectrum disorder, examined using similar assessment protocols, were pooled (n = 301) and subdivided according to history of regression. Those with regression (n = 62), 20.5% of the combined cohort, were contrasted with those without regression (n = 241) at first assessment (age range 19–60 months) and at 2-year follow-up on a range of measures. The regression group was significantly more functionally impaired, with regard to intellectual function (p < .001), language development (p < .001), and to severity of autism (p < .01) at both T1 and T2. Only 14 (23.3%) had a clearly identified underlying etiology [24 (18.6%) in the non-regressive group]. There were no significant differences between those who had regressed ‘from normal’ and those who had regressed ‘from low’ functioning.

Abstract
AIM Clinical developmental phenotyping of four- to five-year-old children with febrile seizures (FSs). METHODS Children with FS (n = 157, corresponding to 3.7% of the targeted general population of four-five-year-olds) had been identified at child healthcare centres in Gothenburg. Parents of 73 children (41 boys, 32 girls) accepted participation in the present study. The assessments included a neuropaediatric assessment, Movement ABC, Wechsler Preschool and Primary Scale of Intelligence-III and parent questionnaires (Five-to-Fifteen (FTF) and Strengths and Difficulties Questionnaire (SDQ)). Hospital records were reviewed, when applicable. RESULTS One-third of the children had at least one DSM-5 neurodevelopmental disorder diagnosis or marked developmental problems within areas of attention, activity regulation, behaviour, speech and language, general cognition or motor functioning. No differences were found between children with single vs recurrent or simple vs complex FS. CONCLUSION Febrile seizure are relatively often associated with Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations (ESSENCEs). We found no indications that ESSENCE might be caused by FS per se. However, the results suggest that child healthcare professionals should consider the possibility of ESSENCE in children with a history of FS.

Abstract
INTRODUCTION Recent evidence suggests an underlying movement disruption may be a core component of autism spectrum disorder (ASD) and a new, accessible early biomarker. Mobile smart technologies such as iPads contain inertial movement and touch screen sensors capable of recording subsecond movement patterns during gameplay. A previous pilot study employed machine learning analysis of motor patterns recorded from children 3-5 years old. It identified those with ASD from age-matched and gender-matched controls with 93% accuracy, presenting an attractive assessment method suitable for use in the home, clinic or classroom. METHODS AND ANALYSIS This is a phase III prospective, diagnostic classification study designed according to the Standards for Reporting Diagnostic Accuracy Studies guidelines. Three cohorts are investigated: children typically developing (TD); children with a clinical diagnosis of ASD and children with a diagnosis of another neurodevelopmental disorder (OND) that is not ASD. The study will be completed in Glasgow, UK and Gothenburg, Sweden. The recruitment target is 760 children (280 TD, 280 ASD and 200 OND). Children play two games on the iPad then a third party data acquisition and analysis algorithm (Play.Care, Harimata) will classify the data as positively or negatively associated with ASD. The results are blind until data collection is complete, when the algorithm's classification will be compared against medical diagnosis. Furthermore, parents of participants in the ASD and OND groups will complete three questionnaires: Strengths and Difficulties Questionnaire; Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations Questionnaire and the Adaptive Behavioural Assessment System-3 or Vineland Adaptive Behavior Scales-II. The primary outcome measure is sensitivity and specificity of Play.Care to differentiate ASD children from TD children. Secondary outcomes measures include the accuracy of Play.Care to differentiate ASD children from OND children. ETHICS AND DISSEMINATION This study was approved by the West of Scotland Research Ethics Service Committee 3 and the University of Strathclyde Ethics Committee. Results will be disseminated in peer-reviewed publications and at international scientific conferences. TRIAL REGISTRATION NUMBER NCT03438994; Pre-results.

Abstract
OBJECTIVES Reported childhood prevalence of autism varies considerably between studies and over time, and general health status has been little investigated. We aimed to investigate contemporary prevalence of reported autism by age, and general health status of children/young people with and without autism. DESIGN Secondary analysis of Scotland's Census, 2011 data. Cross-sectional study. SETTING General population of Scotland. PARTICIPANTS All children (n=916 331) and young people (n=632 488) in Scotland. MAIN OUTCOME MEASURES Number (%) of children/young people reported to have autism and their general health status; prevalence of autism; prevalence of poor health (fair, bad and very bad health); odds ratios (95% confidence intervals) of autism predicting poor health, adjusted for age and gender and OR for age and gender in predicting poor health within the population with reported autism. RESULTS Autism was reported for 17 348/916 331 (1.9%) children aged 0-15, and 7715/632 488 (1.2%) young people aged 16-24. The rate increased to age 11 in boys and age 10 in girls, reflecting age at diagnosis. Prevalence was 2.8% at age 10 (4.4% for boys; 1.1% for girls), and 2.9% at age 11 (4.5% for boys; 1.1% for girls). 22.0% of children and 25.5% of young people with autism reported poor health, compared with 2.0% and 4.4% without autism. Autism had OR=11.3 (11.0 to 11.7) in predicting poor health. Autistic females had poorer health than autistic males, OR=1.6 (1.5 to 1.8). CONCLUSION Accurate information on the proportion of autistic children and their health status is essential plan appropriate prevention and intervention measures and provide resources for those who may put demand on services designed for autistic people.
