A description of medical conditions in adults with autism spectrum disorder: A follow-up of the 1980s Utah/UCLA Autism Epidemiologic Study

Health economic evaluation of Autism Adapted Safety Plans: findings on feasibility of tools from a pilot randomised controlled trial

BACKGROUND

Autism Adapted Safety Plans (AASP) have been proposed to help prevent self-harm and suicidality among autistic adults. The introduction of such plans not only needs to be clinically effective but also cost-effective. The aim of this work was to establish how the cost-effectiveness of AASP could be assessed. Specifically, whether tools and techniques used to collect data for health economic evaluation of the intervention are feasible and acceptable to autistic people.

METHODS

A feasibility and external pilot randomised controlled trial of the AASP intervention was conducted. Autistic adults recruited from diverse locations in England and Wales were randomised to either: AASP and usual care, or usual care only. Health economics tools (bespoke and adapted) were developed and focus groups were undertaken with participants, including autistic adults (n = 15), their family members/carers (n = 5), and service providers (n = 10), to determine their acceptability and feasibility. Tools considered worth further exploration were interviewer administered to participants during the pilot trial at baseline and at 6 months. Interviewer notes were used to record any issues reported while completing the tools. Response rates on the questions and completeness of the tools, along with participant feedback in the interviewer notes was assessed.

RESULTS

Standard Gamble and Time-Trade Off approaches to measure health status were judged inappropriate to measure health outcomes with autistic adults experiencing suicidal ideation and with a history of self-harm. Contingent valuation and discrete choice experiments were also considered inappropriate, due to the heavy cognitive burden on respondents. The EQ-5D-5L/VAS, resource utilisation questionnaire and time-travel questionnaire were considered acceptable by participants. Response and completion rates (as a percentage of all returned questionnaires) for resource utilisation questionnaire (> 85%), time-travel questionnaire (> 79%), EQ-5D-5L (> 96%) and EQ-5D-VAS (> 87%) were good in general. Participants needed clear guidance and interviewer support to enable questionnaire completion.

CONCLUSIONS

It is feasible and acceptable to collect relevant data on resource utilisation, and costs of accessing care and the EQ-5D-5L in a future definitive trial. Clear guidance and interviewer support on how to complete the questionnaires and explanations of the importance of questions to the research would help autistic participants completing the health economic tools.

A scoping review of clusters of multiple long-term conditions in people with intellectual disabilities and factors impacting on outcomes for this patient group

People with intellectual disabilities (ID) are vulnerable to multiple long-term conditions (MLTC). However, in the UK, there are no individual strategies tailored for them. This study synthesised evidence on prevalence of MLTC in people with ID alongside risk factors, outcomes and preventative strategies. The scoping review used the tool Abstrackr to search retrieved articles from three bibliographic databases. Of 933 articles initially screened and further identified, 20 papers met our inclusion criteria. Our findings revealed significant data on prevalence of MLTC in people with ID across the studies, but very limited data on clusters or patterns of co-occurrence in this population. The majority of papers explored risk factors and strategies for prevention of MLTC, but far fewer compared outcomes by MLTC. The identified gaps in the literature indicate the need for further research to identify clusters of MLTC and tailored prevention strategies to reduce poor outcomes in this population.

Sleep disturbances in subjects with autism spectrum disorder: A parental perspective

OBJECTIVE

To investigate the prevalence of sleep disturbances (SDs), their related comorbidities, interventions and the impact on the family for individuals with current SDs and those who had SDs in the past.

METHODS

Members of the Italian national association of parents of persons with autism (ANGSA) completed an anonymous online survey collecting demographic data, the presence of comorbidities and specific information on sleep arrangement and sleep disorders using a modified version of the of the Sleep Disturbance Scale for Children (SDSC).

RESULTS

The final sample consisted of 143 participants, 90 patients presented current SDs (C_SDs) and 53 reported previous SDs (P_SDs). In the C_SDs group, the most prevalent sleep disorders were related to insomnia and, especially, difficulty falling asleep; a high number of individuals presented with restless sleep. Also, the parents in the P_SDs group retrospectively reported a high prevalence of insomnia with difficulty falling asleep, night awakenings and restless sleep. Parents reported that sleep hygiene practice were effective in less than one third of cases in both groups and the most used compound was immediate-release melatonin, followed by antihistamines and then benzodiazepines, antipsychotics, and antidepressants, with approximately 60-70% reported efficacy. Parents of both groups reported that insomnia negatively affected their children behavior and caused stress, mood changes or physical fatigue in their daily life.

CONCLUSION

Our study shows that insomnia is most prevalent in individuals with autism with several consequences on children and family behavior and quality of life. As reported by parents, melatonin might be helpful for sleep disturbances in these children and the causes of restless sleep need further investigations.

ECHO autism adult healthcare: Training community clinicians to provide quality care for autistic adults

Autistic adults experience significant unmet healthcare needs, with opportunities for improvement in both the systems and the practitioners who serve this population. Primary care physicians/practitioners (PCPs) are a natural choice to provide comprehensive care to autistic adults but often lack experience in serving this population. This pilot study developed and tested an Extension for Community Healthcare Outcomes (ECHO) Autism model adapted from our previous work, focused specifically on training PCPs in best-practice care for autistic adults. The project was informed directly by the perspectives and preferences of autistic adults, caregivers, and PCPs. Two consecutive cohorts of PCPs participated in ECHO Autism Adult Healthcare sessions. Each cohort met 1 h twice a month for 6 months, with 37 PCPs (n = 20 in Cohort 1, and n = 17 in Cohort 2) participating. Based on findings from the first cohort, adjustments were made to refine the session preparation, curriculum, conduct of the ECHO, resources, and evaluation. After participation in the ECHO Autism program, PCP self-efficacy and satisfaction improved, while the number of perceived barriers did not change. Knowledge did not improve significantly in Cohort 1, but after adjustments to the training model, participants in Cohort 2 showed significant knowledge gains. While attention to systems of care is critical to addressing barriers in healthcare in the autistic population, the ECHO Autism Adult Healthcare model is feasible and holds promise for improving PCP satisfaction and self-efficacy in working with autistic adults.

Health conditions in autism: Defining the trajectory from adolescence to early adulthood

Autistic adults, as compared to non-autistic adults, have increased rates of nearly all medical and psychiatric conditions. Many of these conditions begin in childhood, although few longitudinal studies have been conducted to examine prevalence rates of these conditions from adolescence into early adulthood. In this study, we analyze the longitudinal trajectory of health conditions in autistic youth, compared to age and sex-matched non-autistic youth, transitioning from adolescence into early adulthood in a large integrated health care delivery system. The percent and modeled prevalence of common medical and psychiatric conditions increased from age 14 to 22 years, with autistic youth having a higher prevalence of most conditions than non-autistic youth. The most prevalent conditions in autistic youth at all ages were obesity, neurological disorders, anxiety, and ADHD. The prevalence of obesity and dyslipidemia rose at a faster rate in autistic youth compared to non-autistic youth. By age 22, autistic females showed a higher prevalence of all medical and psychiatric conditions compared to autistic males. Our findings emphasize the importance of screening for medical and psychiatric conditions in autistic youth, coupled with health education targeted at this population, to mitigate the development of adverse health outcomes in autistic adults.

Autism in Women

Relative to males, women with autism spectrum disorder (ASD) have neurobiological and clinical presentation differences. Recent research suggests that the male/female ASD prevalence gap is smaller than previously reported. Sex differences in symptom presentation as well as the male bias of ASD account for delayed/missed diagnosis among women. Investigating ASD and providing psychological evaluation referrals for women who are struggling socially and present with complex mental health conditions (e.g., ADHD, depression), even when they do not show typical autistic characteristics, is important. Accurate diagnosis facilitates understanding of challenges, increases access to treatments, and alleviates the burden of ASD.

Quality of Life, Neurosensory Disorders and Co-Occurring Medical Conditions in Individuals on the Spectrum, with a Special Focus on Females Diagnosed with Autism: A Systematic Review

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that has a high prevalence and a significant economic impact. Our knowledge regarding neurosensory disorders and co-occurring medical conditions in the ASD population is limited, particularly for autistic women. Most of the studies include male participants or do not make comparisons with their female counterparts. The objective of this systematic review article is to explore the quality of life as well as the prevalence of neurosensory disorders and co-occurring medical conditions in individuals on the spectrum, with a special focus on autistic females. The literature search was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. A protocol of this systematic review was designed a priori and was registered in the PROSPERO database (registration number: CRD42022330368). We concluded that numerous medical areas were of concern. Autistic females are more likely than their male counterparts with ASD to suffer from psychiatric conditions such as post-traumatic stress syndrome, depression, and eating disorders. They are also more likely to report GI-related disturbances and chronic pain. Further investigations are warranted to determine quality of life, as well as the prevalence and severity of neurosensory disorders in individuals with ASD, specifically studies comparing autistic females with their male counterparts. The information derived from these studies will help develop better support systems for individuals with autism, particularly females on the spectrum, in pursuit of improving their quality of life.

A practical approach to identifying autistic adults within the electronic health record

The electronic health record (EHR) provides valuable data for understanding physical and mental health conditions in autism. We developed an approach to identify charts of autistic young adults, retrieved from our institution's de-identified EHR database. Clinical notes within two cohorts were identified. Cohort 1 charts had at least one International Classification of Diseases (ICD-CM) autism code. Cohort 2 charts had only autism key terms without ICD-CM codes, and at least four notes per chart. A natural language processing tool parsed medical charts to identify key terms associated with autism diagnoses and mapped them to Unified Medical Language System Concept Unique Identifiers (CUIs). Average scores were calculated for each set of charts based on captured CUIs. Chart review determined whether patients met criteria for autism using a classification rubric. In Cohort 1, of 418 patients, 361 were confirmed to have autism by chart review. Sensitivity was 0.99 and specificity was 0.68 with positive predictive value (PPV) of 0.97. Specificity improved to 0.81 (sensitivity was 0.95; PPV was 0.98) when the number of notes was limited to four or more per chart. In Cohort 2, 48 of 136 patients were confirmed to have autism by chart review. Sensitivity was 0.95, specificity was 0.73, and PPV was 0.70. Our approach, which included using key terms, identified autism charts with high sensitivity, even in the absence of ICD-CM codes. Relying on ICD-CM codes alone may result in inclusion of false positive cases and exclusion of true cases with autism.

Coping-resilience profiles and experiences of stress in autistic adults

Emerging studies allude to high stress in autistic adults. Considering the detrimental impact of stress on health outcomes, examining individual resources which may influence the extent to which stress is experienced (e.g., coping and resilience) is vital. Using a person-focused approach, this study aimed to identify coping-resilience profiles, and examine their relations to general perceived stress and daily hassles in a sample of autistic adults (N = 86; aged 19-74 years). Cluster analysis identified four coping-resilience profiles (i.e., high cope/ low resilience, low cope/ high resilience, engage cope/ high resilience, and disengage cope/ low resilience). The high cope/ low resilience and disengage cope/ low resilience groups had significantly higher general perceived stress than the remaining groups. No significant group differences were noted in relation to daily hassles. Jointly addressing coping and resilience may be beneficial on the perceived stress experienced in autistic adults. The use of coping-resilience profiles may also allow for the personalization of stress management and support options in the autistic adult population.

Prevalence and factors associated with overweight, obesity, and hypertension in a large clinical sample of adults with autism spectrum disorder

Adults with autism spectrum disorder (ASD) are at risk for excess bodyweight and hypertension, yet the prevalence of and clinical predictors for these health conditions remain unknown. The objective of this study was to assess the prevalence of overweight, obesity, and hypertension in a large clinical sample of adults with a confirmed diagnosis of ASD and to examine potential clinical predictors. This retrospective chart review study included adult subjects (≥ 20 years) with ASD who had been seen within the past 5 years at a multidisciplinary developmental disorders clinic. Data collected from the electronic health record included age, sex, race and ethnicity, cognitive ability, language ability, body mass index (BMI), hypertension, and use of second generation antipsychotic medications (SGAs). Of 622 adults with a confirmed diagnosis of ASD potentially eligible for the study, 483 (78%) had one or more notes in their records from the past 5 years. Those with recent notes were 23% female, 89% White, and had a mean (SD) age of 28.1 (7.1) years. Overall prevalence estimates for adults represented by this predominantly male, White, and young clinical sample were 28% (95% CI 24%, 32%) for overweight (BMI 25-29.9 kg/m²), 35% (95% CI 31%, 40%) for obesity (≥ 30 kg/m²), and 11% (95% CI 9%, 15%) for hypertension. Controlling for age and sex, intellectual disability (ID) was significantly associated with BMI (p = 0.003) but not hypertension (p = 0.69); those with moderate or more severe ID had a mean BMI that was 2.26 kg/m² (95% CI 0.96, 3.57) lower than those with no ID. Controlling for age and sex, neither language ability, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) subtype of autism, nor past or current use of SGAs were significantly associated with BMI or hypertension. The study identified a high prevalence of overweight and obesity in adults with ASD consistent with the prevalence of these medical comorbidities in the U.S. population.

Autism and chronic ill health: an observational study of symptoms and diagnoses of central sensitivity syndromes in autistic adults

BACKGROUND

Autistic adults, particularly women, are more likely to experience chronic ill health than the general population. Central sensitivity syndromes (CSS) are a group of related conditions that are thought to include an underlying sensitisation of the central nervous system; heightened sensory sensitivity is a common feature. Anecdotal evidence suggests autistic adults may be more prone to developing a CSS. This study aimed to investigate the occurrence of CSS diagnoses and symptoms in autistic adults, and to explore whether CSS symptoms were related to autistic traits, mental health, sensory sensitivity, or gender.

METHODS

The full sample of participants included 973 autistic adults (410 men, 563 women, mean age = 44.6) registered at the Netherlands Autism Register, who completed questionnaires assessing autistic traits, sensory sensitivity, CSS, physical and mental health symptoms. The reliability and validity of the Central Sensitization Inventory (CSI) in an autistic sample was established using exploratory and confirmatory factor analyses. Chi2 analyses, independent t-tests, hierarchical regression and path analysis were used to analyse relationships between CSS symptoms, autistic traits, measures of mental health and wellbeing, sensory sensitivity, age and gender.

RESULTS

21% of participants reported one or more CSS diagnosis, and 60% scored at or above the clinical cut-off for a CSS. Autistic women were more likely to report a CSS diagnosis and experienced more CSS symptoms than men. Sensory sensitivity, anxiety, age and gender were significant predictors of CSS symptoms, with sensory sensitivity and anxiety fully mediating the relationship between autistic traits and CSS symptoms.

LIMITATIONS

Although this study included a large sample of autistic adults, we did not have a control group or a CSS only group. We also could not include a non-binary group due to lack of statistical power.

CONCLUSIONS

CSS diagnoses and symptoms appear to be very common in the autistic population. Increased awareness of an association between autism and central sensitisation should inform clinicians and guide diagnostic practice, particularly for women where CSS are common and autism under recognised.

Co-occurring conditions and racial-ethnic disparities: Medicaid enrolled adults on the autism spectrum

Evidence suggests that autistic adults have higher odds of developing several co-occurring conditions, but less is known about disparities by race and ethnicity in this population. Using 2008-2012 Medicaid Analytic eXtract (MAX) data, we (i) identify the prevalence of co-occurring conditions among the population of autistic adult Medicaid beneficiaries compared to a matched sample of those without an autism spectrum disorder (ASD) diagnosis, (ii) conduct logistic regression to estimate odds ratios for these health conditions predicted by an autism diagnosis, and (iii) estimate odds of having these health conditions as predicted by racial/ethnic group among the autistic population only. Overall, autistic adults did not have higher prevalence of some major health conditions (cardiovascular conditions, stroke, cancer, cardiovascular disease), but they did have higher odds of others (nutrition conditions, epilepsy, disorders of the central nervous system). Analysis by racial/ethnic group, however, shows that Black, Hispanic, and Asian autistic beneficiaries had higher odds of diabetes, hospitalized cardiovascular diseases, and hypertension, among other conditions. Policymakers should be aware that racial disparities found in the general population persist in the autistic population and should work to implement systems and programs to improve screening and preventive care for minority autistic populations. LAY SUMMARY: Autistic adults may have several co-occurring physical and mental health conditions, which could differ by racial/ethnic group. We find that, compared to the general Medicaid population, autistic adult Medicaid beneficiaries have elevated odds of some health conditions, like epilepsy and nutrition conditions, as well as some psychiatric conditions, such as anxiety and attention disorders. We also find that many of the same health disparities by racial/ethnic group in the general population persist among the autistic adult Medicaid population. For example, Black, Hispanic, and Asian Medicaid autistic beneficiaries have higher odds of diabetes, and Black and Hispanic autistic beneficiaries have higher odds of obesity and nutrition conditions than white autistic beneficiaries.

The Association Between Obesity and Key Health or Psychosocial Outcomes Among Autistic Adults: A Systematic Review

Obesity is linked with health and psychosocial outcomes among many populations. However, it is unclear the extent to which obesity is linked with these outcomes among autistic adults. We searched seven research databases for articles examining the association between obesity and autistic adults' health and psychosocial outcomes. Three studies found that obesity was associated with health outcomes, including: in-hospital mortality, risk of type II diabetes, cardiovascular disease, and number of co-occurring medical conditions. One study found no significant association between autism diagnosis, mental health conditions, and body mass index. Obesity increases the risk of in-hospital mortality and some chronic conditions among autistic adults, highlighting the need for clinicians trained to promote weight management among autistic adults.

Health profiles of adults with autism spectrum disorder: Differences between women and men

The purpose of the present study was to investigate the hypothesis that women with autism have poorer health compared with men with autism, and compared with women without autism. Utilizing electronic health records drawn from a single health care system serving over 2 million individuals, 2119 adults with diagnosed autism spectrum disorders were compared with age- and sex-matched controls. When considering health care utilization, we found evidence of multiplicative risk for conditions within some domains (i.e., nutrition conditions, neurologic disease, psychiatric conditions, and sleep disorders) such that women with autism spectrum disorder (ASD) experienced double jeopardy-meaning they had greater rates of health care utilization within a domain than what would separately be expected by virtue of being a woman and having ASD. For other domains (i.e., endocrine disorders, gastrointestinal disorders), the risk was additive such that being a female and having ASD were both associated with higher health care utilization, but there were no significant interaction effects. It was only with respect to one domain (cardiovascular) that rates of health care utilization were reflective of neither ASD diagnosis nor sex. Overall, our findings suggest that women with ASD are a vulnerable subgroup with high levels of health care utilization. LAY SUMMARY: This study asked whether women with autism have poorer health compared with men with autism, and compared with women without autism. To answer this question, we used data from electronic health records. We found that women with autism spectrum disorder (ASD) were at the greatest risk for health problems such as nutrition conditions, neurologic disease, psychiatric conditions, and sleep disorders. More research on health of women with ASD is needed.

Practice Tools for Screening and Monitoring Insomnia in Children and Adolescents with Autism Spectrum Disorder

Between 50-80% of children with autism spectrum disorder (ASD) have insomnia, which adversely affects their mental and physical health. However, there is no consensus to-date on suitable tools for insomnia screening and monitoring in daily clinical practice. An expert panel of child neuropsychiatry and sleep specialists, with expertise in children with neurodevelopmental disabilities, recommends: (1) performing insomnia screening of all children with ASD; (2) considering discussion or referral to a sleep specialist when comorbid sleep disorders are suspected. The panel further developed structured, brief screening and monitoring tools to facilitate insomnia screening and management in daily practice, monitor treatment effectiveness and standardize and compare outcomes across clinical settings to improve care and well-being of children with ASD and their families.

Autistic Adult Health and Professional Perceptions of It: Evidence From the ASDEU Project

The Autism Spectrum Disorders in the European Union (ASDEU) survey investigated the knowledge and health service experiences of users and providers to generate new hypotheses and scientific investigations that would contribute to improvement in health care for autistic adults. An online survey designed for autistic adults, carers of autistic adults, and professionals in adult services was translated into 11 languages and distributed electronically by organizations and in-country adult service facilities in 2017; 522 autistic adults, 442 carers, and 113 professionals provided answers to the health questions. Professionals, the majority in non-medical services, appeared to be poorly informed about whether certain co-occurring conditions were more frequent in autistic adults than typical adults-especially some medical conditions, suicide attempts, accidents, and pain. A minority of autistic adults reported preventive health behaviors such as routine health check-ups. The majority of users and providers expressed the desire to make health care services more user-friendly for autistic adults. Among the three groups, <20% of responders knew an organization or clinician which has developed a way to monitor health, and prevent poor health, that works well for adults on the autism spectrum. The results point to means for better management of co-occurring conditions associated with autism in adulthood in order to reduce hospital admissions and potential areas of improvement in health and social services for autistic adults. Specifically, efforts should be focused on (1) professionals' education on risks for co-occurring conditions in autistic adults; (2) promoting preventive health behaviors; (3) making services user-friendly for autistic adults and their families; and (4) encouraging knowledge of good local services.

Health Status of Adults with Autism Spectrum Disorder

Individuals diagnosed with autism spectrum disorder (ASD) have a higher probability of developing co-occurring mental or physical health conditions. However, little is known about how these health conditions develop and impact the lives of the adult ASD population. This paper reviewed existing studies concerning factors affecting the health status of adults with ASD and described their outcomes and prevalence. A systematic search of electronic databases yielded 21 studies eligible to be included. The most common physical problems affecting health were epilepsy and immune, gastrointestinal, and sleep disorders. Mental health disorders, most prominently mood and anxiety disorders and OCD, were also strong factors for determining health in adults. Future research should focus on measuring the overall health status of the adult ASD population.

Impact of COVID-19 on Community Participation and Mobility in Young Adults with Autism Spectrum Disorders

Transportation and mobility for community participation is difficult for persons with Autism Spectrum Disorders (ASD) under normal circumstances, but the impact of COVID-19 made access even more challenging. Researchers used a single-subject design to examine patterns of change from before and after the COVID-19 pandemic in community mobility and participation as measured by GPS and daily participation questionnaires. Participants were young adults with ASD between the ages of 21 and 27 (4 males, 2 females) who were enrolled in a subsequent study. Community mobility and participation decreased for all participants in both essential and non-essential activities. Additionally, the number of trips for participants decreased substantially in the after COVID-19 periods, as did the variability in modes of transit.

A Systematic Review of Healthcare Professionals’ Knowledge, Self-Efficacy and Attitudes Towards Working with Autistic People

Healthcare professionals play a vital role in identifying and supporting autistic people. This study systematically reviewed empirical research examining healthcare professionals’ knowledge, self-efficacy and attitudes towards working with autistic people. Thirty-five studies were included. The included studies sampled a range of countries and professional backgrounds. A modified quality assessment tool found the quality of the included studies was moderately good. Narrative synthesis indicated that healthcare professionals report only moderate levels of autism knowledge and self-efficacy, and often lack training. Variation within and between countries and professional background was not explained by demographic factors. The reviewed evidence suggests health professionals’ limited knowledge and self-efficacy in working with autistic people is a challenge to the provision of healthcare for autistic individuals.

The Prevalence of Diabetes in Autistic Persons: A Systematic Review

Background:

It has been proposed that autistic individuals are at an increased risk of type 1 and type 2 diabetes. Improved understanding of diabetes prevalence in autistic persons will help inform resource allocation for diabetes-related public health measures for this patient group.

Objective:

To conduct a systematic review of published literature pertaining to type 1 and type 2 diabetes prevalence in autistic individuals, including comparison with their non-autistic peers.

Methods:

Eligibility criteria included studies investigating the prevalence of diabetes in autistic individuals, as well as having been published in the English language. A systematic search of online databases (MEDLINE, PsycINFO, CINAHL, EMBASE and PubMed) was conducted on 4^th April 2020. Additional approaches included the ancestry method, grey literature searches and expert consultation. Studies were qualitatively analysed with reporting quality appraised.

Results:

19 eligible studies were identified, 7 of which provided type-specific diabetes prevalence data. Of 15 studies that included a non-autistic control group, 9 reported a higher diabetes prevalence among autistic persons, with a statistically significant difference in 4 studies. Studies demonstrating a higher diabetes prevalence in autistic groups had higher average study population sizes and reporting quality ratings.

Conclusion:

It is uncertain whether diabetes is significantly more prevalent in autistic persons relative to their non-autistic peers, though larger studies suggest a trend in this direction. Nevertheless, diabetes is a significant public health issue for the autistic community, which may require a tailored approach for identification and management.

Global prevalence of obesity, overweight and underweight in children, adolescents and adults with autism spectrum disorder, attention-deficit hyperactivity disorder: A systematic review and meta-analysis

Individuals with autism spectrum disorder (ASD) or attention-deficit hyperactivity disorder (ADHD) may have unhealthy bodyweight. This meta-analysis was performed to understand the weight status in individuals with ASD or ADHD. PubMed, Embase, Cochrane and ISI Web of Science databases were searched from inception until June 2020 to identify relevant studies. Prevalence estimates and their 95% confidence intervals (CIs) of obesity, overweight and underweight were separately pooled using random-effects models. A total of 95 studies were included in the meta-analysis. The pooled estimates of the prevalence of obesity, overweight and underweight were 21.8%, 19.8% and 6.4% in individuals with ASD and 14.7%, 20.9% and 4.0% in individuals with ADHD. In subgroup analyses, an increasing trend in the prevalence of unhealthy weight was observed from children aged 2 to 5 years to adults with ASD (obesity: from 16.7% to 31.3%, overweight: from 16.2% to 27.2%, underweight from 5.3% to 8.6%) and from children aged 6 to 12 years to adults with ADHD (obesity: from 13.5% to 19.3%, overweight: from 18.8% to 31.2%). The worrisome epidemic of obesity and overweight in individuals with ASD, ADHD highlighted the need for weight management.

Physical health of autistic girls and women: a scoping review

BACKGROUND

There is a growing recognition of sex and gender influences in autism. Increasingly, studies include comparisons between sexes or genders, but few have focused on clarifying the characteristics of autistic girls'/women's physical health.

METHODS

A scoping review was conducted to determine what is currently known about the physical health of autistic girls/women. We screened 1112 unique articles, with 40 studies meeting the inclusion criteria. We used a convergent iterative process to synthesize this content into broad thematic areas.

RESULTS

Autistic girls/women experience more overall physical health challenges compared to non-autistic girls/women and to autistic boys/men. Emerging evidence suggests increased prevalence of epilepsy in autistic girls/women compared to non-autistic girls/women and to autistic boys/men. The literature also suggests increased endocrine and reproductive health conditions in autistic girls/women compared to non-autistic girls/women. Findings regarding gastrointestinal, metabolic, nutritional, and immune-related conditions are preliminary and inconsistent.

LIMITATIONS

The literature has substantial heterogeneity in how physical health conditions were assessed and reported. Further, our explicit focus on physical health may have constrained the ability to examine interactions between mental and physical health. The widely differing research aims and methodologies make it difficult to reach definitive conclusions. Nevertheless, in keeping with the goals of a scoping review, we were able to identify key themes to guide future research.

CONCLUSIONS

The emerging literature suggests that autistic girls/women have heightened rates of physical health challenges compared to non-autistic girls/women and to autistic boys/men. Clinicians should seek to provide holistic care that includes a focus on physical health and develop a women's health lens when providing clinical care to autistic girls/women.

Aging Well on the Autism Spectrum: An Examination of the Dominant Model of Successful Aging

There is a gap in our knowledge of aging with autism. The present study examined the applicability of the popular gerontology concept of "aging well" to autistic adults. Using survey data, a model of "aging well" was operationalised and applied to 92 autistic adults and 60 controls. A very small proportion (3.3%) of autistic adults were found to be aging well. Significantly less autistic adults were "maintaining physical and cognitive functioning" and "actively engaging with life" in comparison to controls. Whilst important differences in health and functioning status were found, the current dominant model of "aging well" is limited for examining autistic individuals. Suggested adjustments include development of a broader, more flexible and strengths -based model.

Psychiatric and Medical Profiles of Autistic Adults in the SPARK Cohort

This study examined lifetime medical and psychiatric morbidity reported by caregivers of 2917 autistic adults participating in the US research cohort SPARK. Participants were 78.4% male, 47.3% had intellectual disability, and 32.1% had persistent language impairments. Childhood language disorders (59.7%), speech/articulation problems (32.8%), sleep (39.4%) and eating problems (29.4%), motor delays (22.8%) and history of seizure (15.5%) were the most frequently reported clinical features. Over two thirds (67.2%) had been diagnosed with at least one psychiatric disorder (anxiety disorders: 41.1%; ADHD: 38.7%). Compared to verbally fluent participants, those with language impairments had lower frequencies of almost all psychiatric disorders. Female sex and older age were associated with higher medical and psychiatric morbidity.

Barriers to Healthcare for Persons with Autism: A Systematic Review of the Literature and Development of A Taxonomy

Purpose: This review aimed to 1) synthesize extant research on barriers to healthcare access experienced by persons with autism, their caregivers, and health-care providers; and 2) present a taxonomy of barriers to physical healthcare for individuals with autism.Method: Systematic searches were conducted in five electronic databases. Methodological rigor was assessed using the Quality Assessment Tool for Studies with Diverse Designs. Thematic analysis was used to classify barriers and to develop a taxonomy.Results: In total, 31 articles were included in the review. The resulting taxonomy consisted of four themes: 1) Challenges Associated with Autism-related Characteristics; 2) Health-care Provider-based Issues; 3) Healthcare System Issues; and 4) Patient-related factors.Conclusions: Barriers to healthcare access for persons with autism are prevalent and occur at the patient, provider, and system levels. The taxonomy developed may facilitate measurement of barriers within health-care facilities and prompt identification of areas where interventions are warranted to improve care.

Caring for Adult Patients With Autism in the Critical Care Setting

Many adults with autism spectrum disorders (ASDs) are admitted as an inpatient, and much has been reported on their ASD-related characteristics and aggressive behaviors that complicate their care during hospitalizations. A variety of surgical and medical clinical conditions have required their admissions in the critical care unit. A limited number of case studies are present for hospitalized adults with ASD; most literature about young children was on how to provide care for them. An interdisciplinary approach with a focus on determining information specific to adult patients with ASD, medical problems or common causes of challenging behaviors, and medication history, as well as nutritional needs, is essential in meeting the care needs of autistic adults. Suggestions informed by multiple sources of evidence are presented to assist critical care nurses on how to provide support to care needs of adult patients with ASD during their hospital stay and transition to home.

The Mental and Physical Health of Older Adults With a Genetic Predisposition for Autism

Autism commonly aggregates in families, with twin studies estimating heritability to be around 80%. Subclinical autism-like characteristics have also been found at elevated rates in relatives of autistic probands. Physical and psychiatric conditions have been reported at elevated rates in autistic children and adults, and also in their relatives. However, to date, there has been no exploration of how aging may affect this pattern. This study examined cross-sectional data from the ongoing online PROTECT study. A total of 20,220 adults aged 50 years and older reported whether they have an autistic first-degree relative. In total, 739 older adults reported having an autistic first-degree relative (AFDR group) and 11,666 were identified as having no family history of any neurodevelopmental disorder (NFD group). The AFDR group demonstrated significantly higher frequencies of self-reported psychiatric diagnoses and a greater total number of co-occurring psychiatric diagnoses than the NFD group. Furthermore, the AFDR group reported elevated current self-report symptoms of depression, anxiety, traumatic experience, and post-traumatic stress than the NFD group. By contrast, few differences between AFDR and NFD groups were observed in physical health conditions, and no differences were observed in the total number of co-occurring physical health diagnoses. These findings suggest that adults who have an AFDR may be at greater risk of poor mental, but not physical, health in later life. Older adults with autistic relatives may benefit from close monitoring to mitigate this susceptibility and to provide timely intervention. Autism Res 2020, 13: 641-654. © 2020 The Authors. Autism Research published by International Society for Autism Research published by Wiley Periodicals, Inc. LAY SUMMARY: Children and adults with an autistic relative have been found to experience more psychiatric difficulties than those with no family links to autism. However, a few studies have explored what happens when these individuals get older. Examining over 20,000 adults age 50+, we found that older adults with an autistic relative experienced elevated rates of most psychiatric conditions but not physical conditions. Older adults with autistic relatives may benefit from close monitoring to mitigate this susceptibility and to provide timely intervention.

Aging and Autism: Understanding, Intervention and Proposals to Improve Quality of Life

BACKGROUND

The population with autism spectrum disorder (ASD) has been increasing and is currently estimated to be 1 in 58 births. The increased prevalence of ASD together with the lack of knowledge on the processes of aging in this population, the support needed at this stage of life, and the associated risk factors, have led to an urgent need for further research.

METHODS

This study provides a review of the literature on social- and health-related conditions that may appear when persons with ASD grow old.

RESULTS

In addition to the autism-related conditions, different neurological, genetic, and environmental factors may be involved in the process of aging. In this complex setting, this study provides proposals that may guide the development of support services that may improve the quality of life for aging people with ASD.

CONCLUSION

Aging in ASD is emerging as a growing problem, which requires immediate planning and targetted treatment development.

Cohort profile: the Australian Longitudinal Study of Adults with Autism (ALSAA)

​PURPOSE: There is a significant knowledge gap regarding the lives of adults on the autism spectrum. Some literature suggests significant health and mental health inequalities for autistic adults, yet there is a lack of comprehensive longitudinal studies exploring risk factors. Further, most research does not include the perspective of autistic adults in its conduct or design. Here, we describe the baseline characteristics and inclusive research approach of a nationwide longitudinal study. ​PARTICIPANTS: The Autism Cooperative Research Centre for Living with Autism's Australian Longitudinal Study of Adults with Autism (ALSAA) is a questionnaire-based longitudinal study of autistic adults (25+ years old) with follow-up at 2-year intervals. Autistic advisors were involved in each stage of research apart from data analysis. Three questionnaires were developed: self-report, informant report (ie, proxy report) and carers (ie, carer experiences and characteristics). ​FINDINGS TO DATE: An inclusive research protocol was developed and agreed with autistic advisors. Baseline data were collected from 295 autistic adults (M=41.8 years, SD=12.0) including 42 informant responses, 146 comparison participants and 102 carers. The majority of autistic participants (90%) had been diagnosed in adulthood (M=35.3 years, SD=15.1). When compared with controls, autistic adults scored higher on self-report measures of current depression and anxiety. Participant comments informed ongoing data gathering. Participants commented on questionnaire length, difficulty with literal interpretation of forced response items and expressed gratitude for research in this area. ​FUTURE PLANS: A large comprehensive dataset relating to autistic adults and their carers has been gathered, creating a good platform for longitudinal follow-up repeat surveys and collaborative research. Several outputs are in development, with focus on health service barriers and usage, caregivers, impact of diagnosis in adulthood, further scale validations, longitudinal analyses of loneliness, suicidal ideation, mental illness risk factors and other areas. Baseline data confirm poorer mental health of autistic adults. The ALSAA demonstrates a working approach to inclusive research.

The risk of overweight and obesity in children with autism spectrum disorders: A systematic review and meta-analysis

Multiple studies have suggested that autism spectrum disorders seem to increase the risk of overweight and obesity. We examined the pooled prevalence and relative risk of developing overweight or obesity among children with autism spectrum disorders in a systematic review and meta-analysis. We searched PubMed, Scopus, ProQuest, and Web of Science databases and subsequently screened the records to identify studies that reported prevalence of overweight and/or obesity in children with ASD and matched groups of neurotypical children. DerSimonian-Laird random-effects meta-analyses were performed to examine pooled prevalence and relative risk of obesity in children with autism spectrum disorders using the "meta" package in R software. Among children with autism spectrum disorders, the prevalence of obesity was 22.2%. Children with ASD had a 41.1% greater risk (P = .018) of development of obesity. Non-Caucasian race, increasing age, female sex, and living in the United States emerged as positive moderators of the association between autism spectrum disorders and prevalence of overweight or obesity. Autism spectrum disorders seem to increase the risk of childhood obesity. Increased awareness of this association may allow the implementation of early interventions to reduce obesity and prevent potential deterioration of quality-of-life in this population.

Evaluation of agomelatine for the treatment of sleep problems in adults with autism spectrum disorder and co-morbid intellectual disability

PURPOSE

Intellectual disability (ID) and autism spectrum disorder (ASD) are common, co-occurring developmental disorders and are frequently associated with sleep problems. This study aimed to assess the effectiveness and tolerability of agomelatine as a pharmacotherapy for sleep problems in ASD adults with ID.

METHOD

A randomised, crossover, triple-blind, placebo-controlled clinical trial, with two three-month periods of treatment starting with either agomelatine or placebo and a washout period of two weeks. Ambulatory circadian monitoring (24 hours/7 days) evaluated total sleep time (TST) as the primary outcome variable.

RESULTS

Participants (N=23; 35±12 years old; 83% male) had a median of three (interquartile range (IQR) 1-4) co-morbidities and were taking a median of five (IQR 2-7) prescribed drugs. Before agomelatine or placebo treatment, all subjects presented with insomnia symptoms, including sleep latency (100% abnormal, 55±23 minutes) or TST (55% abnormal, 449±177 minutes), and 66% had circadian rhythm sleep-wake abnormalities with rhythm phase advancements according to the M5 sleep phase marker values. During the three-month agomelatine treatment, night TST significantly increased by a mean of 83 minutes (16% abnormal, 532±121 minutes), together with a phase correction (M5 1:45±2:28 hours vs. 3:15±2:20 hours), improving sleep stability in wrist temperature rhythm (0.43±0.29 vs. 0.52±0.18 AU). Adverse events were mild and transient.

CONCLUSIONS

Agomelatine was effective and well tolerated for treating insomnia and circadian rhythm sleep problems present in adults with ASD and ID.

Impact of environmental pollution, dietary factors and diabetes mellitus on Autism Spectrum Disorder (ASD)

Autism spectrum disorder (ASD) is complex neurodevelopmental condition described by impairments in three main behavioral areas: social deficits, impaired communication, and repetitive behaviors. Despite many years of vast study, the causes of ASD are still unknown. Various risk factors including genetic, infectious, metabolic and immunological have been investigated however, environmental, nutritional and diabetes related risk factors have not received sufficient attention. This study has provided an insight into the comprehensive interaction between environmental pollution, dietary factors and diabetes mellitus that could lead to the advancement of this debilitating neurodevelopment disorder. The literature search was done using PubMed and Google Scholar databases up to October 2018. Key words "Environmental Pollution", "Nutritional Factors", "Diabetes Mellitus", "Autism Spectrum Disorder" were selected.

Autism aging

Many people perceive autism spectrum disorder (ASD) as a childhood disorder, yet ASD is a lifelong condition. Although little is known about the mental and physical health issues of aging individuals with ASD, there are increasing numbers of older adults being diagnosed with ASD. Although there has been a recent "call to action" (to address lack of knowledge and the dearth of services and programs for aging individuals with autism, the authors think it is also important for those who are involved in educational programs related to gerontology and geriatrics settings to be aware of "autism aging." This term conceptualizes the demographics, person and contextual factors, and intellectual awareness of the trends and patterns of ASD as a life course challenge and opportunity for well-being and quality of life. The purposes of this article are to (1) provide a general overview of autism issues and to examine several dimensions of ASD in the context of the emergent and relevant scholarship in the adult and aging domain, (2) propose how to address the "gap" in the literature on autism and aging in terms of a conceptual model and by improving the methodology, and (3) to discuss the implications of these dimensions for educators in gerontology and geriatrics, and for those professionals who work in clinical and health care services. It is the goal of the authors to have this article represent a general introduction to ASD and to be a part of the foundation for educational awareness for educators in gerontology and geriatrics.

Patient-Level Medication Regimen Complexity in an Adolescent and Adult Population with Autism Spectrum Disorders

BACKGROUND

Adults with autism spectrum disorder (ASD) frequently experience polypharmacy. However, there is limited understanding of how to quantify medication complexity in this vulnerable population.

OBJECTIVES

This study examined medication administration difficulty using the Medication Regimen Complexity Index (MRCI) tool in adolescents and adults with ASD. The outcomes compared the mean total MRCI score with the medication count, described MRCI contributions for over-the-counter medication (OTC), and compared MRCI scores by patient characteristics.

METHODS

This was a retrospective chart review of patients aged 7-45 years (mean = 20.1) enrolled in a primary care ASD transitions program. Each patient's listed medications were counted and then scored using the validated MRCI tool.

RESULTS

For the 142 patients studied, mean total MRCI was 14.6 ± 14.6 (range 0-89) and mean medication count was 6.3 ± 5.4 (range 0-38). For patients on 0-4 medications (66 of 142; 46.5%), the mean MRCI was 5.5 ± 4.2, 5-9 medications (50 of 142; 35.2%) the mean MRCI was 15.2 ± 6.8, and 10-38 medications (26 of 142; 18.3%) the mean MRCI was 36.5 ± 18.9 (p<0.001). Sixty percent (85 of 142) reported OTC use, which contributed 26.6% to the mean total MRCI. Reported benzodiazepine (mean MRCI 25.8 ± 17.2), antiepileptic (mean MRCI 23.7 ± 16.9), antipsychotic (mean MRCI 19.7 ± 15.9), or antidepressant (mean MRCI 17.0 ± 14.8) use received higher MRCI scores compared to nonuse (p<0.001 for all except antidepressants [p=0.004]). Total MRCI did not differ significantly by age group, sex, or attention-deficit-hyperactivity disorder (ADHD) medication use (stimulant or nonstimulant).

CONCLUSIONS

Medication regimen complexity in adolescents and adults with ASD was increased significantly for individuals taking ≥ 5 medications. Central nervous system agent use, other than ADHD therapy, identified patients with higher regimen complexity. The related clinical effects of these findings warrant further investigation.

Interoceptive impairments do not lie at the heart of autism or alexithymia

Quattrocki and Friston (2014) argued that abnormalities in interoception—the process of representing one’s internal physiological states—could lie at the heart of autism, because of the critical role interoception plays in the ontogeny of social-affective processes. This proposal drew criticism from proponents of the alexithymia hypothesis, who argue that social-affective and underlying interoceptive impairments are not a feature of autism per se, but of alexithymia (a condition characterized by difficulties describing and identifying one’s own emotions), which commonly co-occurs with autism. Despite the importance of this debate for our understanding of autism spectrum disorder (ASD), and of the role of interoceptive impairments in psychopathology, more generally, direct empirical evidence is scarce and inconsistent. Experiment 1 examined in a sample of 137 neurotypical (NT) individuals the association among autistic traits, alexithymia, and interoceptive accuracy (IA) on a standard heartbeat-tracking measure of IA. In Experiment 2, IA was assessed in 46 adults with ASD (27 of whom had clinically significant alexithymia) and 48 NT adults. Experiment 1 confirmed strong associations between autistic traits and alexithymia, but yielded no evidence to suggest that either was associated with interoceptive difficulties. Similarly, Experiment 2 provided no evidence for interoceptive impairments in autistic adults, irrespective of any co-occurring alexithymia. Bayesian analyses consistently supported the null hypothesis. The observations pose a significant challenge to notions that interoceptive impairments constitute a core feature of either ASD or alexithymia, at least as far as the direct perception of interoceptive signals is concerned.

This article suggests that impairments in interoception—the process of representing one’s internal physiological states—do not lie at the heart of either autism or alexithymia.

Prevalence of long-term health conditions in adults with autism: observational study of a whole country population

OBJECTIVES

To investigate the prevalence of comorbid mental health conditions and physical disabilities in a whole country population of adults aged 25+ with and without reported autism.

DESIGN

Secondary analysis of Scotland's Census, 2011 data. Cross-sectional study.

SETTING

General population.

PARTICIPANTS

94% of Scotland's population, including 6649/3 746 584 adults aged 25+ reported to have autism.

MAIN OUTCOME MEASURES

Prevalence of six comorbidities: deafness or partial hearing loss, blindness or partial sight loss, intellectual disabilities, mental health conditions, physical disability and other condition; ORs (95% CI) of autism predicting these comorbidities, adjusted for age and gender; and OR for age and gender in predicting comorbidities within the population with reported autism.

RESULTS

Comorbidities were common: deafness/hearing loss-14.1%; blindness/sight loss-12.1%; intellectual disabilities-29.4%; mental health conditions-33.0%; physical disability-24.0%; other condition-34.1%. Autism statistically predicted all of the conditions: OR 3.3 (95% CI 3.1 to 3.6) for deafness or partial hearing loss, OR 8.5 (95% CI 7.9 to 9.2) for blindness or partial sight loss, OR 94.6 (95% CI 89.4 to 100.0) for intellectual disabilities, OR 8.6 (95% CI 8.2 to 9.1) for mental health conditions, OR 6.2 (95% CI 5.8 to 6.6) for physical disability and OR 2.6 (95% CI 2.5 to 2.8) for other condition. Contrary to findings within the general population, female gender predicted all conditions within the population with reported autism, including intellectual disabilities (OR=1.4).

CONCLUSIONS

Clinicians need heightened awareness of comorbidities in adults with autism to improve detection and suitable care, especially given the added complexity of assessment in this population and the fact that hearing and visual impairments may cause additional difficulties with reciprocal communication which are also a feature of autism; hence posing further challenges in assessment.

A scoping review of what is known of the physical health of adults with autism spectrum disorder

Little research has been carried out on the physical health of people with autism spectrum disorder (ASD). From the studies conducted with both children and adults, few studies have moved beyond retrospective record analysis and survey and conducted health assessment. The majority of the studies are from the United States of America with a small number conducted in Europe. A scoping review was conducted to determine what is known of the physical health of adults with ASD and to identify research gaps. In addition to studies of adults, this review includes studies of children to determine possible health trajectories. From the findings, it can be stated with confidence that people with ASD have a high rate of comorbidity and increased risk for chronic disease.

Genetic analysis of very obese children with autism spectrum disorder

Autism spectrum disorder (ASD) is defined by the triad of deficits in social interactions, deficits in communication, and repetitive behaviors. Common co-morbidities in syndromic forms of ASD include intellectual disability, seizures, and obesity. We asked whether very obese children with ASD had different behavioral, physical and genetic characteristics compared to children with ASD who were not obese. We found that very obese children with ASD had significantly poorer scores on standardized behavioral tests. Very obese boys with ASD had lower full scale IQ and increased impairments with respect to stereotypies, communication and social skills. Very obese girls with ASD had increased impairments with respect to irritability and oppositional defiant behavior. We identified genetic lesions in a subset of the children with ASD and obesity and attempted to identify enriched biological pathways. Our study demonstrates the value of identifying co-morbidities in children with ASD as we move forward towards understanding the biological processes that contribute to this complex disorder and prepare to design customized treatments that target the diverse genetic lesions present in individuals with ASD.

Mid-life social outcomes for a population-based sample of adults with ASD

Adults with autism spectrum disorders (ASD) fall short of social outcomes of non-ASD peers in mid-life, as documented by currently published research. The aim of the current study was to extend what is known about social functioning, employment, independent living, and use of social services by examining details of the current life status for a population-based sample of adults with ASD (mean age = 35.5 years, range = 22.2-51.4). We collected outcome data via direct assessment and informant report for 169 individuals. Three-fourths of the sample had cognitive abilities in the intellectually disabled range. Social functioning outcomes, as a single measure, mirror those reported previously for other samples, including samples with a high proportion of individuals with normal range intellectual abilities, with 20% achieving the most independent outcomes and 46% requiring high levels of support across most life areas. Participant subgroups who achieved maximal outcomes represented a range of social and intellectual abilities for several outcome metrics. Participants used high levels of public and private supports, yet specific areas of clear, unmet need were also identified. Autism Res 2018, 11: 142-152. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.

LAY SUMMARY

This paper describes the social functioning outcomes for 169 adults with autism spectrum disorders in mid-life. Adult participants spanned the full range of functional and cognitive ability levels, with over 75% functioning in the cognitively impaired range. While summary descriptions of outcomes for this sample were similar to those reported for other groups of adults, this report provides detailed information regarding employment outcomes, social relationships, leisure activities, participation in the community, residential situations, public service use, and involvement with law enforcement.

Problems managed and medications prescribed during encounters with people with autism spectrum disorder in Australian general practice

Autism spectrum disorder is associated with high rates of co-occurring health conditions. While elevated prescription rates of psychotropic medications have been reported in the United Kingdom and the United States, there is a paucity of research investigating clinical and prescribing practices in Australia. This study describes the problems managed and medications prescribed by general practitioners in Australia during encounters where an autism spectrum disorder was recorded. Information was collected from 2000 to 2014 as part of the Bettering the Evaluation and Care of Health programme. Encounters where patients were aged less than 25 years and autism spectrum disorder was recorded as one of the reasons for encounter and/or problems managed ( n = 579) were compared to all other Bettering the Evaluation and Care of Health programme encounters with patients aged less than 25 years ( n = 281,473). At 'autism spectrum disorder' encounters, there was a significantly higher management rate of psychological problems, and significantly lower management rates of skin, respiratory and general/unspecified problems, than at 'non-autism spectrum disorder' encounters. The rate of psychological medication prescription was significantly higher at 'autism spectrum disorder' encounters than at 'non-autism spectrum disorder' encounters. The most common medications prescribed at 'autism spectrum disorder' encounters were antipsychotics and antidepressants. Primary healthcare providers need adequate support and training to identify and manage physical and mental health concerns among individuals with autism spectrum disorder.

Assessment of Sleep in Children with Autism Spectrum Disorder

Sleep disturbances in children with autism spectrum disorder (ASD) are significantly more prevalent than found in typically developing (TD) children. Given the detrimental impact of poor sleep on cognitive, emotional, and behavioral functioning, it is imperative to screen and assess for sleep disturbances in this population. In this paper, we describe the screening and assessment process, as well as specific measures commonly used for assessing sleep in children with ASD. Advantages and limitations for use in children with ASD are discussed. While subjective measures, such as parent-report questionnaires and sleep diaries, are the most widely used, more objective measures such as actigraphy, polysomnography, and videosomnography provide additional valuable information for both diagnostic purposes and treatment planning. These objective measures, nonetheless, are limited by cost, availability, and feasibility of use with children with ASD. The current review provides an argument for the complementary uses of both subjective and objective measures of sleep specifically for use in children with ASD.

Addressing medical needs of adolescents and adults with autism spectrum disorders in a primary care setting

Little has been reported about how to improve health care access and delivery for adolescents and adults with autism spectrum disorder. To understand the contributions to the health disparities in the autism spectrum disorder population, we conducted two independent research approaches to learn about current medical needs. A retrospective chart review was performed to evaluate medical comorbidities and medication use. A focus group was also created to address barriers faced in providing medical care. Of 126 charts reviewed, 49% (n = 62) had intellectual disability, 49% (n = 62) had attention-deficit hyperactivity disorder, 52% (n = 65) had anxiety, 41% (n = 52) had obesity, 31% (n = 39) with a history of aggressive behavior, 31% (n = 31) had depression, 22% (n = 28) had seizures, and 9% (n = 11) had hypertension. A Medical Regimen Complexity Index score was determined to examine medication use trends in the autism spectrum disorder population. Medical Regimen Complexity Index scores were significantly higher for patients with intellectual disability, patients with seizures, and patients with a history of aggressive behavior. Both the focus group and our pre-visit assessment identified the waiting room and waiting time as barriers to care. Understanding the comorbidities, polypharmacy, and medical barriers should provide a better understanding of the current health care access and delivery needs of adolescents and adults with autism spectrum disorder.

Priority service needs and receipt across the lifespan for individuals with autism spectrum disorder

Individuals with Autism Spectrum Disorder (ASD) have a range of health, community, and social support needs across the lifespan that create age‐specific challenges in navigating service sectors. In this study, we set out to identify the priority needs of individuals with ASD across the lifespan, and the factors that predict receiving priority services. Participants included 3,317 individuals with ASD from a Canada‐wide online caregiver survey, stratified into five age groups (preschool, elementary school age, adolescence, emerging adulthood, adulthood). Priority receipt was calculated as a ratio of current services that corresponded to individualized priority need. Age‐stratified Poisson regression analyses were used to identify the sociodemographic, clinical and systemic predictors of priority receipt. Results indicate that the distribution of priority need varied by age, except for social skills programming, which was a high across all groups. The number of high and moderate priority needs diversified with age. Overall, 30% of individuals had none of their priority needs met and priority receipt decreased with age. Systemic factors were most consistently related to priority receipt across the lifespan. Understanding patterns and correlates of priority needs and use that currently exist in different age groups can inform policies to improve service access.
