Health Conditions and Functional Status in Adults with Autism: A Cross-Sectional Evaluation

Involvement of Autistic Adults in Recreational Activities

PURPOSE

Participation in recreational activities (RA) has a positive impact on quality of life. The involvement of autistic adults in RA has rarely been documented. This study aimed to describe the RA involvement of autistic adults with and without intellectual disability (ID), and identify potential facilitators and barriers to their participation.

METHODS

We conducted a wide-ranging online survey of autistic people aged 16 years and over living in Québec, Canada. This study focused on the questions concerning RA. We recruited participants through social media and community partners.

RESULTS

The sample consisted of 316 participants. The most frequent activities engaged in were cultural outings, city walks, and nature walks. About 40% of participants frequently engaged in at least three different activities. About 12% did not engage in any frequent activity. Nearly 95% of participants reported participating in at least one activity with others, with family members identified most often as partners. For all participants, involvement in RA was facilitated by interest in the activity, a comfortable environment, and being accompanied by a friend or family member. Conversely, presence of a crowd, high cost of activities, and limited availability of RA restricted respondents' participation.

CONCLUSIONS

RA of autistic adults are diverse in terms of number and type of activities engaged in. Family members play a crucial role in the respondents' RA involvement. Parent proxy identified barriers stemming mainly from the environment. Barriers identified by self-respondents came from the interaction of autistic traits with the environment.

Transcallosal white matter and cortical gray matter variations in autistic adults ages 30-73 years: A bi-tensor free water imaging approach

Background: Autism spectrum disorder (ASD) has long been recognized as a lifelong condition, but brain aging studies in autistic adults aged >30 years are limited. Free water, a novel brain imaging marker derived from diffusion MRI (dMRI), has shown promise in differentiating typical and pathological aging and monitoring brain degeneration. We aimed to examine free water and free water corrected dMRI measures to assess white and gray matter microstructure and their associations with age in autistic adults. Methods: Forty-three autistic adults ages 30-73 years and 43 age, sex, and IQ matched neurotypical controls participated in this cross-sectional study. We quantified fractional anisotropy (FA), free water, and free water-corrected FA (fwcFA) across 32 transcallosal white matter tracts and 94 gray matter areas in autistic adults and neurotypical controls. Follow-up analyses assessed age effect on dMRI metrics of the whole brain for both groups and the relationship between dMRI metrics and clinical measures of ASD in regions that significantly differentiated autistic adults from controls. Results: We found globally elevated free water in 24 transcallosal tracts in autistic adults. We identified negligible differences in dMRI metrics in gray matter between the two groups. Age-associated FA reductions and free water increases were featured in neurotypical controls; however, this brain aging profile was largely absent in autistic adults. Additionally, greater autism quotient (AQ) total raw score was associated with increased free water in the inferior frontal gyrus pars orbitalis and lateral orbital gyrus in autistic adults. Limitations: All autistic adults were cognitively capable individuals, minimizing the generalizability of the research findings across the spectrum. This study also involved a cross-sectional design, which limited inferences about the longitudinal microstructural changes of white and gray matter in ASD. Conclusions: We identified differential microstructural configurations between white and gray matter in autistic adults and that autistic individuals present more heterogeneous brain aging profiles compared to controls. Our clinical correlation analysis offered new evidence that elevated free water in some localized white matter tracts may critically contribute to autistic traits in ASD. Our findings underscored the importance of quantifying free water in dMRI studies of ASD.

Diabetes mellitus in privately insured autistic adults in the United States

LAY ABSTRACT

Diabetes is a chronic health condition that is challenging to manage. Estimates of how common diabetes is among non-autistic adults are available, but improved estimates for autistic adults are needed. The purpose of this study was to obtain improved diabetes estimates for autistic adults. We analyzed a large private health insurance claims database to estimate how common diabetes was among autistic adults, and how likely autistic adults were to have diabetes compared to non-autistic adults at 5-year age intervals throughout adulthood (e.g. 18-22, 23-27). We found that diabetes was more common among autistic adults than non-autistic adults and that autistic adults were significantly more likely than non-autistic adults to have diabetes throughout most of adulthood. Our findings suggest that autistic adults may be more likely than non-autistic adults to experience diabetes in adulthood. The development of diabetes support services and programs that accommodate autistic adults' individual needs are important for future study to promote positive diabetes outcomes for autistic adults.

Sensory Profile-2 in Autism Spectrum Disorder: An Analysis within the International Classification of Functioning, Disability and Health Framework

Autism spectrum disorder (ASD) is characterized by impairments in many functional areas requiring long-term interventions to promote autonomy. This study aims to map The Sensory Profile™ 2 (SP-2), one of the most widely used assessment tools in children with ASD, with the International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY), developed by the World Health Organization (WHO). This will allow the identification of the functional dimensions covered by this instrument and the comparison with the ICF shortlist proposed for autism (ICF Core Set [ICF-CS]). The deductive content analysis described in the ICF Linking Rules was followed, along with a systematized process including statistical and reasoning techniques that could contribute to the improvement of ICF linking studies (Cohen's Kappa and percentage of agreement). 218 codes were identified, 71% of them were codes related to the body functions chapters, mainly linked to perceptual functions (b160), emotional functions (b152), and temperament and personality functions (b126). Concerning activities and participation chapters (29%) the most frequently used codes were: focusing attention (d160), carrying out daily routine (d230), and walking (d450). Even though the SP-2 items do not assess most of the functional features regarded as essential in the ASD ICF-CS, SP-2 encompasses a majority of problems concerning body functions. This instrument may be considered as part of a multidimensional assessment approach, to complement other sources that are more likely to assess activity and participation dimensions and guide a functional intervention.

Use of preventive service and potentially preventable hospitalization among American adults with disability: Longitudinal analysis of Traditional Medicare and commercial insurance

Objective

Examine the association between traditional Medicare (TM) vs. commercial insurance and the use of preventive care and potentially preventable hospitalization (PPH) among adults (18+) with disability [cerebral palsy/spina bifida (CP/SB); multiple sclerosis (MS); traumatic spinal cord injury (TSCI)] in the United States.

Methods

Using 2008-2016 Medicare and commercial claims data, we compared adults with the same disability enrolled in TM vs. commercial insurance [Medicare: n = 21,599 (CP/SB); n = 7,605 (MS); n = 4,802 (TSCI); commercial: n = 11,306 (CP/SB); n = 6,254 (MS); n = 5,265 (TSCI)]. We applied generalized estimating equations to address repeated measures, comparing cases with controls. All models were adjusted for age, sex, race/ethnicity, and comorbid conditions.

Results

Compared with commercial insurance, enrolling in TM reduced the odds of using preventive services. For example, adjusted odds ratios (OR) of annual wellness visits in TM vs. commercial insurance were 0.31 (95% confidence interval (CI): 0.28-0.34), 0.32 (95% CI: 0.28-0.37), and 0.19 (95% CI: 0.17-0.22) among adults with CP/SB, TSCI, and MS, respectively. Furthermore, PPH risks were higher in TM vs. commercial insurance. ORs of PPH in TM vs. commercial insurance were 1.50 (95% CI: 1.18-1.89), 1.83 (95% CI: 1.40-2.41), and 2.32 (95% CI: 1.66-3.22) among adults with CP/SB, TSCI, and MS, respectively. Moreover, dual-eligible adults had higher odds of PPH compared with non-dual-eligible adults [CP/SB: OR = 1.47 (95% CI: 1.25-1.72); TSCI: OR = 1.61 (95% CI: 1.35-1.92), and MS: OR = 1.80 (95% CI: 1.55-2.10)].

Conclusions

TM, relative to commercial insurance, was associated with lower receipt of preventive care and higher PPH risk among adults with disability.

Prevalence of current smoking and association with meeting 24-h movement guidelines: Results from a national convenience sample of autistic adults

LAY ABSTRACT

Cigarette smoking is a leading risk behavior for cardiovascular disease; yet its prevalence and determinants are not clear in autistic adults. We examined the prevalence of current smoking and its association between meeting 24-h movement (i.e. sleep, physical activity, and sedentary behavior) guidelines in a self-selecting convenience sample of 259 autistic adults in the United States. We found that current smokers met fewer 24-h movement guidelines. Most significant, those who had insufficient sleep and those with high levels of sedentary behavior were more likely to be current smokers. Therefore, targeting these movement behaviors may be potential intervention targets for smoking cessation.

Metabolic syndrome in adults with autistic traits: associated psychological, behavioral, and biological factors in females and males - a PharmLines initiative

Background

While cardiovascular diseases is highly prevalent and an important cause of mortality in autistic adults, knowledge on their increased cardiovascular risk is limited. Hence, this study aimed to investigate psychological, behavioral, and physical factors associated with metabolic syndrome (MetS) in adults with autistic traits.

Methods

In total, 17,705 adults from the Lifelines Cohort were included and categorized using Autism Spectrum Quotient-10 sum-scores. The quartiles with highest (HQ-traits-group females: n = 2,635; males: n = 1803) and lowest levels of autistic traits (LQ-traits-group, n = idem) were analyzed. Using multivariable logistic regression, the associations between MetS and (self-reported and interviewed) psychological, behavioral, and physically measured factors in these stratified groups were investigated.

Results

Among females, MetS was more common in the HQ-traits-group than in the LQ-traits-group (10.0% versus 7.5%, p < 0.01), while this was not the case among males (HQ-traits-group 13.8% versus LQ-traits-group 13.1%, p = 0.52). In both the female and male HQ-traits-group, the presence of MetS was associated with poorer self-reported health, less daily physical activity, and altered leukocyte counts.

Conclusion

These findings underline the relevance of adequate cardiovascular prevention in adults with higher levels of autistic traits. Future research could gain more insight into the relationship between cardiovascular risk and autistic traits in females, and into tailored cardiovascular prevention.

Sexually Transmitted Infection Among Adolescents and Young Adults with Autism Spectrum Disorder: A Nationwide Longitudinal Study

The association between autism spectrum disorder (ASD) and subsequent sexually transmitted infections (STIs) and the potential effects of medications on STI risk remain unknown. In all, 5076 adolescents and young adults with ASD and 57,060 age-/sex-matched individuals without ASD were enrolled between 2001 and 2009 and followed-up to the end of 2011 for identification of subsequent STIs. The results revealed that patients with ASD were prone to acquiring an STI [hazard ratio (HR) 3.36] compared with the comparison group. Long-term use of atypical antipsychotics was associated with a lower risk of acquiring an STI later in life compared with nonuse (HR 0.34). We recommend that clinicians closely monitor risky sexual behaviors and STI risk in patients with ASD.

Pregnancy in autistic women and social medical considerations: scoping review and meta- synthesis

Introduction

This article addresses a topic that has been largely overlooked by scientific literature, namely pregnancy in autistic women. Generally, the issue of sexuality in disability, particularly in disabled women, autistic or otherwise, has been underexplored. However, it is necessary to scientifically investigate this topic to propose adequate social and health policies. Therefore, we chose to conduct a scoping review to answer three main questions: "What does it mean for an autistic woman to be pregnant?"; "How do these two conditions coexist?"; "Are health services prepared to receive this population adequately or does autism become a stigma for pregnant women?"

Methods

We conducted a systematic review and qualitative thematic synthesis following the Preferred Reporting Guidelines for Systematic Reviews and Meta-Analyses on autistic women and pregnancy in the last 10 years.

Results

The studies included in our review are 7, extremely diverse in terms of methodologies and sample sizes. Despite the heterogeneity of samples and methodologies, all research tends to highlight the following results. For autistic women during pregnancy, three areas seem to be the most difficult: sensory issues, mood disorders, and relationships with specialists.

Discussion

Our study found that women with ASD face unique challenges during childbirth that differ from those of neurotypical women. Participants often felt belittled, ignored, and uninformed about the care they received, and being placed at the centre of attention was often seen as negative and hindering rather than positive. However, the research shows us how some "expected" results, such as difficulties in breastfeeding, have been disproven.

Factor associated with the occurrence of epilepsy in autism: a systematic review

This systematic review aimed to identify factors significantly associated with the occurrence of epilepsy in autistic individuals and to consider the impact of study quality on findings. Electronic databases were systematically searched on October 2nd, 2020 and records retrieved were limited to those published from 2000 onwards. Study quality was categorised as 'good', 'moderate' or 'weak'. Fifty-three studies were included and in studies where the prevalence of epilepsy was reported (n = 257,892), 18,254 (7%) had co-occurring epilepsy. Intellectual disability/cognitive impairment was the most commonly reported risk factor associated with occurrence of epilepsy in autistic individuals. The evidence supporting other, potentially relevant factors was weak and inconsistent and requires further evaluation. Only 9/53 studies were considered 'good' quality.

Measuring the prevalence of autistic traits in a cohort of adults living with HIV or taking HIV pre-exposure prophylaxis and mapping safer-sex barriers and facilitators: a study protocol

INTRODUCTION

Autistic individuals identify with a wider range of sexual orientations than non-autistic individuals, including higher rates of bisexual orientation in autistic men. Gay, bisexual and other men who have sex with men are at greater risk for HIV. Prevalence data of autistic traits in people living with HIV or using Pre-Exposure Prophylaxis (PrEP) for HIV are lacking so far. Such data, combined with insights in barriers and facilitators for safer sex in autistic people living with HIV or using PrEP, are a first step to improve health support for autistic people in HIV clinics. This support is crucial since autistic individuals have worse physical and mental health outcomes. The objective of this research is to determine the prevalence of autistic traits within the group of people living with HIV or using PrEP in Belgium and to describe specific facilitators and barriers for sexual safer behaviour in people living with HIV and PrEP users with autistic traits.

METHODS AND ANALYSIS

The research is a cross-sectional, observational and multicentre study with recruitment of individual participants. The research consists of two phases. In phase 1, adults coming for HIV/AIDS care or HIV PrEP in participating Belgian HIV Reference Centres will be invited to fill in the validated Autism Spectrum Quotient questionnaire. In phase 2, participants with a score above the predefined cut-off for autistic traits (>26), who agreed to be informed about this score, will be invited to complete an additional survey, inquiring facilitators and barriers for sexual safer behaviour.

ETHICS AND DISSEMINATION OF RESULTS

Study results will be published in peer-reviewed journals and presented to Belgian HIV Reference Centres and at conferences.

Increased rates of chronic physical health conditions across all organ systems in autistic adolescents and adults

BACKGROUND

The poorer physical health of autistic adults compared to non-autistic adults has been highlighted by several epidemiological studies. However, research has so far been limited to specific geographical areas and has primarily focused on young autistic individuals (aged 35 years and younger). Recent studies indicate a higher rate of mortality in autistic people, as well as poorer quality of self-reported healthcare interactions. This study aims to determine, first, whether autistic people experience greater levels of non-communicable health conditions and second, whether these are explained by differences in demographics (i.e. sex, country of residence, ethnicity, education level), alcohol use, smoking, body mass index (BMI), or family history of medical conditions.

METHOD

We employed a cross-sectional, convenience-sampling study via an anonymous, online survey of autistic and non-autistic adults (n = 2305, mean age = 41.6, 65.9% female, 49% autistic). The survey asked participants to self-report information about their demographics, autism diagnosis, diet, exercise, sleep, sexual health, substance use, personal medical history, and family medical history (for all first-degree, biological relatives). Binomial logistic regression across four iterative models of increasing complexity was applied to assess rates of physical health conditions. The Benjamini-Hochberg correction was used to account for multiple testing, and only physical health conditions that achieved at least 1% endorsement within the overall sample (n > 22) were included in the analysis to reduce risk of Type I errors. We also used novel network analysis methods to test whether there are increased levels of multimorbidity between autistic and non-autistic people.

RESULTS

There were significantly elevated rates of non-communicable conditions across all organ systems in autistic people, including gastrointestinal, neurological, endocrine, visual, ear/nose/throat, skin, liver and kidney, and haematological conditions. We confirmed previous findings by showing highly significant differences in rates of neurological and gastrointestinal symptoms (p < 0.0001). In addition, we established in the largest sample to date that Ehler-Danlos Syndrome (EDS) was more likely to occur among autistic females compared to non-autistic females. Finally, we found a higher prevalence of Coeliac's disease among autistic individuals compared to non-autistic individuals after controlling for sex, ethnicity, country of residence, alcohol use, smoking, and BMI, but these results became non-significant after accounting for family history.

LIMITATIONS

Our study is biased towards females, white individuals, highly educated people, and UK residents, likely due to sampling biases. Our self-report study design may also exclude those who lack access to computers, or those with intellectual disability. Our network analysis is also limited in size.

CONCLUSIONS

This study provides evidence of widespread, physical health comorbidity that spans nearly all major organ systems in autistic adults compared to non-autistic adults, using both binary logistic regression and network models. Healthcare professionals must be made aware of the range of co-occurring physical health conditions that may be more common among autistic people. However, our findings also point towards potential avenues requiring further exploration, such as the association of autism with both Coeliac's disease and EDS.

Neurological and psychiatric disorders among autistic adults: a population healthcare record study

BACKGROUND

Co-occurring psychiatric disorders are common in autism, with previous studies suggesting 54-94% of autistic individuals develop a mental health condition in their lifetime. Most studies have looked at clinically-recruited cohorts, or paediatric cohorts followed into adulthood, with less known about the autistic community at a population level. We therefore studied the prevalence of co-occurring psychiatric and neurological conditions in autistic individuals in a national sample.

METHODS

This retrospective case-control study utilised the SAIL Databank to examine anonymised whole population electronic health record data from 2001 to 2016 in Wales, UK (N = 3.6 million). We investigated the prevalence of co-occurring psychiatric and selected neurological diagnoses in autistic adults' records during the study period using International Classification of Diseases-10 and Read v2 clinical codes compared to general population controls matched for age, sex and deprivation.

RESULTS

All psychiatric conditions examined were more common amongst adults with autism after adjusting for age, sex and deprivation. Prevalence of attention-deficit hyperactivity disorder (7.00%), bipolar disorder (2.50%), obsessive-compulsive disorder (3.02%), psychosis (18.30%) and schizophrenia (5.20%) were markedly elevated in those with autism, with corresponding odds ratios 8.24-10.74 times the general population. Depression (25.90%) and anxiety (22.40%) were also more prevalent, with epilepsy 9.21 times more common in autism.

CONCLUSIONS

We found that a range of psychiatric conditions were more frequently recorded in autistic individuals. We add to understanding of under-reporting and diagnostic overshadowing in autism. With increasing awareness of autism, services should be cognisant of the psychiatric conditions that frequently co-occur in this population.

Mental health in autistic adults: A rapid review of prevalence of psychiatric disorders and umbrella review of the effectiveness of interventions within a neurodiversity informed perspective

BACKGROUND

Autistic adults have high risk of mental ill-health and some available interventions have been associated with increased psychiatric diagnoses. Understanding prevalence of psychiatric diagnoses is important to inform the development of individualised treatment and support for autistic adults which have been identified as a research priority by the autistic community. Interventions require to be evaluated both in terms of effectiveness and regarding their acceptability to the autistic community.

OBJECTIVE

This rapid review identified the prevalence of psychiatric disorders in autistic adults, then systematic reviews of interventions aimed at supporting autistic adults were examined. A rapid review of prevalence studies was completed concurrently with an umbrella review of interventions. Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were followed, including protocol registration (PROSPERO#CRD42021283570).

DATA SOURCES

MEDLINE, CINAHL, PsycINFO, and Cochrane Database of Systematic Reviews.

STUDY ELIGIBILITY CRITERIA

English language; published 2011-2022; primary studies describing prevalence of psychiatric conditions in autistic adults; or systematic reviews evaluating interventions for autistic adults.

APPRAISAL AND SYNTHESIS

Bias was assessed using the Prevalence Critical Appraisal Instrument and AMSTAR2. Prevalence was grouped according to psychiatric diagnosis. Interventions were grouped into pharmacological, employment, psychological or mixed therapies. Strength of evidence for interventions was assessed using GRADE (Grading of Recommendations, Assessment, Development and Evaluation). Autistic researchers within the team supported interpretation.

RESULTS

Twenty prevalence studies were identified. Many included small sample sizes or failed to compare their sample group with the general population reducing validity. Prevalence of psychiatric diagnoses was variable with prevalence of any psychiatric diagnosis ranging from 15.4% to 79%. Heterogeneity was associated with age, diagnosis method, sampling methods, and country. Thirty-two systematic reviews of interventions were identified. Four reviews were high quality, four were moderate, five were low and nineteen critically low, indicating bias. Following synthesis, no intervention was rated as 'evidence based.' Acceptability of interventions to autistic adults and priorities of autistic adults were often not considered.

CONCLUSIONS

There is some understanding of the scope of mental ill-health in autism, but interventions are not tailored to the needs of autistic adults, not evidence based, and may focus on promoting neurotypical behaviours rather than the priorities of autistic people.

Understanding the Relationship between Distress Behaviour and Health Status of People with Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is associated with complex distress and challenging behaviours that have a negative impact on the everyday life of those with ASD, as well as their parents and carers. These challenging behaviours include negative emotional behaviours, motor behaviours, and changes in routines. Even though challenging behaviours occur in most subjects with ASD, the cause of these largely remains unknown. It has been implicated that these challenging behaviours are associated with a change in the health of those with ASD. More research needs to be conducted that can establish a direct association. Towards this goal, the present study aimed to explore whether health status had an impact on the distressing behaviour in the subjects diagnosed with ASD. We analysed the response from the parents/carers in a Macedonian population of those with ASD, to determine which challenging behaviours were most likely to be observed during a change in health. Based on a scoring system, the manifestation of challenging behaviour was evaluated and compared with the changes in health. Changes in appetite or dietary preferences, irritability and low mood, and loss of previously acquired skills had the greatest association with a change in health. These findings provide early insight into types of challenging behaviours that are directly associated with a change in health. Our results demonstrate a relationship between health status and challenging behaviour in the subject with autism, suggesting that caregivers may need to consider this when choosing strategies for managing challenging behaviour.

[Early death and causes of death of patients with autism spectrum disorders: A systematic review]

To study of premature/early death of autistic patients from the perspective of life course can help families, medical institutions and policy makers better deal with the adverse effects of autism. Several studies have shown that autistic patients have a high risk of death, however, the results are still inconsistent. To assess the risk of mortality among the autistic patients, we undertook a comprehensive search of MEDLINE, Web of Science and EMBASE databases. This paper reviewed the studies on the negative disease outcomes of autism spectrum disorders, including the risk of death, causes of death and several research hotspots in this field. Strict inclusion/exclusion criteria were used. Information was extracted from selected papers, tabulated and synthesized. In the study, 15 studies were included, with a total of 216 045 individuals. The main outcome was all-cause mortality in association with autism and the secondary outcome was cause-specific mortality. The results showed that all-cause mortality was higher for the autistic patients (RR=2.32, 95%CI: 1.98-2.72, I²=87.1%, P < 0.001). Risk ratio showed a greater inequality for female than male (male: RR=2.00, 95%CI: 1.57-2.55, I²=93.2%, P < 0.001; female: RR=4.66, 95%CI: 3.30-6.58, I²=92.0%, P < 0.001). Compared with the unnatural death, the risk of natural death was higher (RR=3.44, 95%CI: 1.27-9.26, I²=80.2%, P=0.025). As autism had many comorbidities, which would bring more health risks and natural deaths possibilities. There were some structural differences in unnatural death. Accidental injury death and suicide were two kinds of causes. Lacking social skills would weaken the ability to ask for help when encountering injuries. This paper put forward some suggestions for futures. First, to well study the comorbidity can reduce the risk of death from a medical point of view. Second, the scientists and policymakers should pay attention to the social environment and provide a safer environment for the autistic patients. Third, for women and for adolescents without cognitive impairment, due to their high risk of suicide, the society should provide them with more supportive social networks and improve their life satisfaction. Fourth, it is necessary to balance the rehabilitation resources in various regions in China and provide more high-quality lifelong rehabilitation monitoring and care services.

Where Do Neurodevelopmental Disorders Go? Casting the Eye Away from Childhood towards Adulthood

Neurodevelopmental disorders (NDDs) encompass a group of complex conditions with onset during the early developmental period. Such disorders are frequently associated with a number of neuropsychiatric features, the most prevalent ones being autism spectrum disorder, attention-deficit/hyperactivity disorder, intellectual disability, communication and specific learning disorders, and motor disorders. These conditions are characterized by wide genetic and clinical variability, and although they were previously conceptualized as childhood-limited disorders, NDDs are progressively being recognized as persistent conditions with a potentially relevant impact on the quality of life and overall functioning during adult life. In addition, emerging evidence seems to point towards the hypothesis of a neurodevelopmental continuum, according to which NNDs could portray different time-dependent outcomes, depending on the severity of the altered brain development. Despite representing lifelong phenotypes, they are often not promptly identified and/or managed in adulthood. In this regard, specific guidelines on clinical and therapeutic approaches for these conditions have not yet been delineated. In this view, future research investigations should be encouraged to broaden available knowledge, characterize the clinical course of NDDs across an individual’s lifespan, and better understand the patterns of aging-related concerns in adults with an NDD diagnosis. Additionally, considering the difficulties many young adults encounter while transitioning from childhood to adult mental health services, new, specific programs should be developed and existing programs should be implemented to improve the transition process and for the management of NDDs in adulthood.

Alexithymia and intolerance of uncertainty predict somatic symptoms in autistic and non-autistic adults

LAY ABSTRACT

Autistic people have more physical health problems than non-autistic people. We were interested in whether autistic people experience more discomfort in their bodies than non-autistic people and whether certain psychological traits contribute to that. A survey was completed online by older adolescents and adults, 51 of whom were autistic, 32 of whom thought they might be autistic but were not diagnosed and 119 who were not autistic. They completed measures of somatic symptoms (daily experience of pain, discomfort, dizziness), alexithymia (difficulty identifying and expressing feelings), interoception (how much people are aware of their bodies) and intolerance of uncertainty (how people handle doubt or uncertainty), and reported any physical or mental health conditions. We found that the autistic participants had more physical and mental health conditions than the non-autistic participants, but even when we took account of this, they experienced higher levels of somatic symptoms. We looked at which psychological factors influenced levels of somatic symptoms across the whole sample, and found that alexithymia, intolerance of uncertainty, having physical health problems, being female and the number of mental health conditions predicted somatic symptoms, while interoception and autism diagnosis did not. The findings suggest that people may be more likely to experience physical discomfort if they are female, and have difficulty identifying and expressing feeling and difficulty tolerating doubt. As these psychological factors are more prominent in autism, we think this is important for physical and mental health providers to know about, so that these psychological factors can be considered when assessing and treating autistic people.

Results of a phase Ib study of SB-121, an investigational probiotic formulation, a randomized controlled trial in participants with autism spectrum disorder

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by core impairments in social communication as well as restricted, repetitive patterns of behavior and/or interests. Individuals with ASD, which includes about 2% of the US population, have challenges with activities of daily living and suffer from comorbid medical and mental health concerns. There are no drugs indicated for the core impairments of ASD. As such, there is a significant need for the development of new medication strategies for individuals with ASD. This first-in-human placebo-controlled, double-blind, crossover study investigated the safety (primary objective) and efficacy of oral SB-121, a combination of L. reuteri, Sephadex® (dextran microparticles), and maltose administered once daily for 28 days in 15 autistic participants. SB-121 was safe and well tolerated. SB-121-associated directional improvements in adaptive behavior measured by Vineland-3 and social preference as measured with eye tracking were noted. These results provide support for further clinical evaluation of SB-121 as a treatment in autistic patients. To evaluate the safety and tolerability of multiple doses of SB-121 in subjects with autism spectrum disorder. Single-center, randomized, placebo-controlled, double-blind, crossover trial. 15 patients with autism spectrum disorder were randomized and analyzed. Daily dosing of SB-121 or placebo for 28 days, followed by approximately a 14 day washout, then 28 days of dosing with other treatment. Incidence and severity of adverse events, presence of Limosilactobacillus reuteri and Sephadex® in stool, and incidence of bacteremia with positive L. reuteri identification. Additional outcomes include changes from baseline on cognitive and behavior tests as well as biomarker levels. Adverse event rates were similar between SB-121 and placebo, with most reported as mild. There were no severe or serious adverse events. No participants had features of suspected bacteremia or notable changes in vital signs, safety laboratory, or ECG parameters from baseline. There was a statistically significant increase from baseline in the Vineland-3 Adaptive Behavior Composite score (p = 0.03) during SB-121 treatment. There was a trend for increased social/geometric viewing ratio following SB-121 treatment compared to placebo. SB-121 was safe and well tolerated. SB-121-associated directional improvements in adaptive behavior measured by Vineland-3 and social preference as measured with eye tracking were noted.Trial registration: clinicaltrials.gov Identifier: NCT04944901.

Burnout among direct support workers of adults with autism spectrum disorder and intellectual disability

BACKGROUND

Direct support workers (DSWs) accompany adults with autism spectrum disorder (ASD) and intellectual disability (ID) in residential care homes. Such DSWs, without specialised ASD training, are exposed to chronic stress linked to supporting ASD-ID clients and must adjust by coping strategies adapted to the needs of the residents. Nevertheless, difficulties adjusting constitute a burnout risk for DSWs, characterised by high levels of emotional exhaustion, depersonalisation and loss of a sense of personal accomplishment. We aimed to describe the burnout of DSWs who support adults with ASD-ID and to identify personal variables (experience and specialised training for ASD) and transactional variables (perceived stress and coping strategies) that could predict and mediate burnout.

METHOD

In total, 125 DSWs accompanying ASD-ID adults on a daily basis were included. Each participant answered four questionnaires measuring burnout, sociodemographic and professional variables, coping strategies and perceived stress.

RESULTS

Five per cent of DSWs were in a state of burnout. Eighteen, six and fifty-nine per cent showed high average scores of emotional exhaustion, depersonalisation and loss of a sense of personal accomplishment, respectively. Being older, specialised training in ASD, stress perceived as a challenge and problem-focused coping strategies were associated with low levels of depersonalisation and loss of a sense of personal accomplishment.

CONCLUSIONS

Understanding the burnout process of ASD-ID DSWs may require the assessment of the organisational characteristics linked to the quality of life of the DSWs and the recognition of their specific needs when facing difficulties. The necessary ASD-focused training and support depends on an appraisal that would be individualised to adult ASD-ID DSWs.

Association between autistic traits and binge drinking: Findings from Japan

PURPOSE

Substance misuse may be elevated in some individuals with autism spectrum disorder (ASD). As yet, however, little is known about the association between autistic traits (AT) and substance use/misuse in adults. This study examined the association between AT and binge drinking (BD) among individuals in Japan.

METHODS

Data were analyzed from 1452 individuals aged 18 and above collected during an online survey in February 2021. Self-reported information was obtained on BD assessed as consuming 5 or more (males) or 4 or more (females) drinks containing any kind of alcohol within a 2-h period. AT were assessed with the Japanese version of the Autism Spectrum Quotient - the AQ-J-10. Logistic regression analysis was used to examine associations.

RESULTS

The prevalence of past-month BD was significantly higher in individuals with AT compared to those without AT (42.7% > 27.6%). In a fully adjusted analysis that controlled for mental health (anxiety, depression) and attention-deficit/hyperactivity disorder symptoms, individuals with AT had significantly higher odds for BD once a week or more often (OR: 1.54, 95%CI: 1.04-2.29). AT were also associated with significantly higher odds for BD among women (OR: 2.27, 95%CI: 1.08-4.76), and those aged 18-34 (OR: 2.37, 95%CI: 1.09-5.18) and aged 60 and above (OR: 2.15, 95%CI: 1.02-4.53).

CONCLUSION

Individuals with AT have higher odds for BD. Increased efforts to detect alcohol use/misuse in adults with AT and AT in adults misusing alcohol may be efficacious in efforts to manage symptoms and eliminate harmful alcohol misuse.

Characterizing the physical and mental health profile of children, adolescents and adults with autism spectrum disorder in Spain

Introduction

Autistic men and women are more likely to experience health issues than the general population, although the available epidemiological studies addressing co-occurrence conditions are limited. This is the first Spanish epidemiologic study addressing the health profile and poor-health exacerbating factors in individuals of all ages with autism spectrum disorder (ASD).

Methods

We analyzed 2,629 registries extracted from Autism Spain's sociodemographic registry (November 2017-May 2020). A descriptive health data analysis was conducted to assess the prevalence of other conditions associated to ASD in the Spanish population. Nervous system disorders (12.9%), mental health diagnoses (17.8%), and other comorbidities (25.4%) were reported. Men-to-women ratio was 4:1.

Results

Women, elder individuals and those with intellectual disability (ID) were at an increased risk of health comorbidities and psychopharmacological exposure. Women were also more prone to severe intellectual and functional impairment. Nearly all individuals had difficulties in their adaptative functioning, especially those with ID (50% of the population). Almost half of the sample received psychopharmacological treatments starting from infancy and early childhood, mostly antipsychotics and anticonvulsants.

Discussion

This study represents an important first approach to the health status of autistic people in Spain and can contribute to the development of public policies and innovative health strategies.

Views about primary care health checks for autistic adults: UK survey findings

BACKGROUND

Compared with the general population, autistic adults experience higher rates of physical and mental health conditions, premature morbidity and mortality, and barriers to health care. A health check for autistic people may improve their health outcomes.

AIM

To establish the views of autistic people towards a primary care health check for autistic people.

DESIGN & SETTING

Cross-sectional questionnaire study in England and Wales.

METHOD

A questionnaire was sent to autistic adults with physical health conditions in England and Wales. A total of 458 people (441 autistic adults and 17 proxy responders) completed the questionnaire.

RESULTS

Most responders (73.4%, n = 336) thought a health check is needed for all autistic people. Around half of the participants thought a health check should be offered from childhood and the health check appointment should last between 15 and 30 minutes. Autistic people were positive about providing primary care staff with contextual information regarding their health and the reasonable adjustments they would like before their health check appointment. Training about autism and the health check was considered important, alongside adequate time for discussions in the health check appointment (all by over 70% of responders). The clinician's autism knowledge, seeing a familiar clinician, environmental adaptations, appropriate information, and accessible appointments were considered particularly important in making a health check accessible.

CONCLUSION

Autistic people and relatives were supportive of a primary care health check for autistic people. Information gathered was used to support the design of a primary care health check for autistic adults.

Multimorbidity patterns and subgroups among autistic adults with intellectual disability: Results from the EFAAR study

LAY ABSTRACT

Multimorbidity relates to having multiple chronic health conditions. It is a risk factor for poor health and reduces life expectancy. Autistic people have multiple chronic health conditions and die prematurely, especially if they have an intellectual disability (autism spectrum disorder and intellectual disability). Certain pathophysiological processes observed in autism spectrum disorder are common to those related to the genesis and/or maintenance of multimorbidity. Furthermore, multimorbidity could be helpful in better identifying patient subgroups in autism spectrum disorder. It is therefore essential to better characterize multimorbidity and its consequences in the subgroup of autism spectrum disorder + intellectual disability individuals to offer them personalized care. We conducted a preliminary study of 63 autism spectrum disorder + intellectual disability adults to classify them according to their multimorbidity and search for a specific combination of chronic health conditions. We observed high and early multimorbidity in this sample and identified four classes of participants, distinguished by their multimorbidity status, independence and number of treatments. In addition, we observed a dominant combination of multimorbidity in our sample, combining immune dysfunction and gastrointestinal disorders, neurological and joint diseases. These findings support the hypothesis that an altered gut-brain relationship is involved in the risk of autism spectrum disorder, its outcome, and its association with chronic health conditions. Although larger studies are needed, our results suggest that subgroups of autism spectrum disorder + intellectual disability individuals can be identified based on their multimorbidity and potentially different ageing trajectories. A more comprehensive and personalized approach is needed to reduce the burden of multimorbidity and increase the quality of life and life expectancy in autism spectrum disorder/ intellectual disability.

Ageing and autism: A longitudinal follow-up study of mental health and quality of life in autistic adults

Background

Poor mental health is known to adversely affect functional abilities, social isolation, and quality of life (QoL). It is, therefore, crucial to consider the long-term impacts of mental health conditions as autistic adults grow older.

Objectives

To explore, in a group of community-based autistic adults, the extent of: (i) autistic traits, co-occurring physical and mental health conditions; (ii) age-related differences in those conditions, and changes over time; and (iii) their impact on everyday living and QoL.

Method

About Sixty-eight autistic adults (aged 19-80 years) participated in the first study (T1); 49 participants from T1 took part in a follow-up at T2 (mean retest interval 2.4 years). Standardised self-report measures of autistic traits, mental health, and QoL were completed at both time points.

Results

Over two-thirds (71%) of autistic adult participants experienced at least one co-occurring condition, and over a third (37%) met the criteria for three or more co-occurring conditions. Mental and physical health difficulties were related to autistic traits and difficulties in everyday life and were consistent predictors of poor QoL at T1 and T2.

Conclusion

Mental health difficulties in autism persisted into older age and did not improve over time. These findings have important implications for mental health provision for autistic adults in older age.

A scoping review of disparities in health and health-care service provisions experienced by adults with autism spectrum disorder

Purpose

Adults with autism spectrum disorder (ASD) are more likely to have a poor health status because of being diagnosed with a range of physical and mental health conditions and experience disparities in health care. The purpose of this study is to find barriers to health care experienced by adults with ASD and find gaps in health care which health-care providers can work to fill.

Design/methodology/approach

This scoping review aimed to identify studies that report on disparities in health and health-care service provisions experienced by adults with ASD. The authors included articles that described health-care disparities for patients with ASD and were published in peer-reviewed journals between January 2010 and April 2022. The authors searched the following databases and medical journals to search for eligible studies: Google Scholar, Pubmed, Elsevier, Sage Publications and Embase. The authors comprehensively searched key terms related to ASD, health care and disparities.

Findings

The core defining features of ASD, which include communication and social impairments and deficits in sensory processing, were found to be barriers in the health-care experience of adults with ASD. Continued research and changes in health care, such as developing interventions to empower patients, adequately training providers and increasing the accessibility of the health-care system, are necessary to ensure adults with ASD receive adequate medical care.

Research limitations/implications

Additionally, clarifying the current literature on this topic can guide future research efforts to explore the influence of factors such as gender and the spectrum of autism itself leading to various levels of abilities and their influence on the health-care experience of adults with ASD.

Practical implications

Overall, the findings from this scoping review underline the importance of providing readily accessible evidence-based, age-appropriate primary and hospital health care for adults with ASD.

Social implications

Further interventions are needed to empower patients, adequately train providers, increase the accessibility of the health-care system, increase support for ASD patients and decrease discrimination.

Originality/value

This paper is a scoping literature review of the original work done by researchers in the field of developmental disorders and health care.

Child and Parental Mental Health as Correlates of School Non-Attendance and School Refusal in Children on the Autism Spectrum

Children on the autism spectrum miss more school than their peers, but limited work has explored why this may be. This study aimed to document the frequency at which children on the autism spectrum miss half and full days of school and the reasons for these absences. Parents of 106 school-aged children on the autism spectrum completed online questionnaires on rates of school non-attendance, family factors, child anxiety, and parental mental health. On average across a four week period, children missed 6 full days of school. The most common reason for full-day absences was school refusal and for half-day absences was medical/therapy appointments. Parental employment status, increased child age, child anxiety, and differing aspects of parental mental health were identified as correlates of specific subtypes of school non-attendance.

Effects of a Gamified, Behavior Change Technique-Based Mobile App on Increasing Physical Activity and Reducing Anxiety in Adults With Autism Spectrum Disorder: Feasibility Randomized Controlled Trial

BACKGROUND

Physical activity (PA) has an impact on physical and mental health in neurotypical populations, and addressing these variables may improve the prevalent burden of anxiety in adults with autism spectrum disorder (ASD). Gamified mobile apps using behavior change techniques present a promising way of increasing PA and reducing sedentary time, thus reducing anxiety in adults with ASD.

OBJECTIVE

This study aimed to compare the effectiveness of a gamified and behavior change technique-based mobile app, PuzzleWalk, versus a commercially available app, Google Fit, on increasing PA and reducing sedentary time as an adjunct anxiety treatment for this population.

METHODS

A total of 24 adults with ASD were assigned to either the PuzzleWalk or Google Fit group for 5 weeks using a covariate-adaptive randomization design. PA and anxiety were assessed over 7 days at 3 different data collection periods (ie, baseline, intervention start, and intervention end) using triaxial accelerometers and the Beck Anxiety Inventory. Group differences in outcome variables were assessed using repeated-measures analysis of covariance, adjusting for age, sex, and BMI.

RESULTS

The findings indicated that the PuzzleWalk group spent a significantly longer amount of time on app use compared with the Google Fit group (F2,38=5.07; P=.01; partial η2=0.21), whereas anxiety was unfavorably associated with increases in light PA and decreases in sedentary time after intervention (all P<.05).

CONCLUSIONS

Further research is needed to clarify the determinants of physical and mental health and their interrelationship in adults with ASD to identify the factors that facilitate the use and adoption of mobile health technologies in these individuals. Despite these mixed results, the small changes in PA or anxiety may be clinically significant for adults with ASD.

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.

Autistic adults have poorer quality healthcare and worse health based on self-report data

BACKGROUND

Recent research suggests that autistic individuals have shorter lifespans and experience worse health (greater health burden) than non-autistic individuals. Small, qualitative studies suggest that autistic adults also experience poor self-reported healthcare quality.

METHODS

An anonymized, cross-sectional, self-report questionnaire was administered to n = 4158 individuals. The study assessed prevalence of chronic health conditions, healthcare quality, differences in overall health inequality score, and effects of the coronavirus pandemic on healthcare quality. We used Fisher's exact tests, binomial logistic regression, and predictive machine learning tools, as appropriate.

RESULTS

The final sample included n = 2649 participants (n = 1285 autistic) aged 16-96 years. Autistic adults reported lower quality healthcare than non-autistic adults across 50/51 items, including poorer access to healthcare and poorer communication, alongside increased anxiety, sensory sensitivity, system-level problems, shutdowns, and meltdowns. Differences between groups were stark: aggregated health inequality scores predicted autism diagnosis, even after stratifying by sex. Autistic adults were also more likely to have chronic health conditions than non-autistic adults. There were no significant differences in healthcare quality for autistic adults before and during the pandemic, although they received relatively poorer quality healthcare than non-autistic adults across both periods.

LIMITATIONS

The study's sampling methods are not likely to capture the perspectives of all autistic individuals, especially those with intellectual disability. Both the autistic and control samples are biased towards UK residents, white individuals, those assigned female at birth, and those who completed an undergraduate degree or higher education. As such, these results may limit their generalizability to other groups. Finally, these results relate to self-reported differences in healthcare quality between autistic and non-autistic adults. The observed group differences may in part reflect differences in perception and communication rather than differences in actual healthcare quality.

CONCLUSIONS

Autistic adults are more likely to have chronic health conditions alongside self-reported lower quality healthcare than others. Health inequalities between these groups are widespread and dramatic; unfortunately, they existed before and have persisted after the onset of the coronavirus pandemic.

The quality of life of people with ASD through physical activity and sports

Among the factors that influence the quality of life of people with Autism Spectrum Disorder (ASD), physical activity and sport are key dimensions of physical well-being. Few studies take into account the perspectives of people with ASD in order to understand the extent of physical well-being and their subjective perception of it. The development of a system of quality of life indicators related to physical activity and sport for people with ASD and their analysis is the aim of this study, providing guidelines for improvement. A study was carried out with a sample of 276 people, professionals (n = 143), family members (n = 73) and people with ASD (n = 60). The people with ASD in the sample belonged to three age categories: children aged 8-12 years, adolescents aged 12-18 years and adults over 18 years. The research team used a qualitative methodology in the collection of information. They adapted three questionnaires, with validated quality of life scales, to guide the interviews and also applied them in the design of the focus group protocols. Subsequently, the research team analysed the information collected in the focus groups with families and professionals using a DELPHI method. A system for coding the responses and qualitative analysis of the responses was also prepared for the analysis of the data by the research team. Finally, the information obtained was compared with a group of representative experts. The results concluded with the elaboration of a system of quality of life indicators related to the dimension of physical well-being, as well as guidelines and proposals that bring together the perspectives of people with ASD in relation to the practice of sport and physical activity. There is a need to increase the practice of sport among people with ASD in order to promote their health, social participation and personal satisfaction. It is concluded that it is not possible to obtain a broad picture of the quality of life of people with ASD and their families due to lack of information. However, the method and the results obtained represent a first approach at national level to increase knowledge about the quality of life of people with ASD.

Experiences of Performing Daily Activities in Middle-Aged and Older Autistic Adults: A Qualitative Study

This is the first study to investigate instrumental activities of daily living in older autistic adults. We conducted interviews with fifteen adults (mean age = 60.1, SD = 7.4, range = 50-73) from Australia with no intellectual disability. Analysis included both deductive and inductive steps, to categorise responses using the Occupational Performance Model Australia and identify themes across participants' experiences. Strengths and challenges were unique to the individual, as were the methods they had developed to manage tasks. Challenges occurred mostly at the interaction between aspects of the environment (sensory, cognitive, social and cultural) and personal factors such as health conditions and sensory sensitivities. Enhanced person-environment fit is needed, as is a shift in wider sociocultural attitudes to enable comfort and autonomy in later life.

Medical symptoms and conditions in autistic women

LAY ABSTRACT

Sex-steroids, such as testosterone, are thought to be one of the biological factors implicated in autism. This relies on the sex bias in the diagnosis of autism (boys are approximately four times more likely to be diagnosed than girls) and findings of associations with fetal testosterone levels in traits and abilities related to autism. The current study aimed to examine the association between medical conditions and physical symptoms, which tend to manifest in adulthood, and autism in females. Moreover, we examined their association with autistic traits throughout the spectrum. We focused on autistic women because there is little research focusing on the healthcare needs of autistic women, but those that exist suggest heightened vulnerability, and lower access to medical care. We find that conditions related to steroid hormones function are more frequent in autistic women and that they correlate with autistic traits. Specifically, we found that body mass index, reproductive system diagnoses, prediabetes symptoms, irregular puberty onset, and menstrual irregularities were significantly more frequent in autistic women and were significantly correlated with autistic traits in neurotypical women. The findings have important implications for raising awareness in autistic women of the possibility of medical conditions which might need medical attention. In addition, healthcare providers should consider these associations when performing healthcare maintenance checks and/or screening for autism.

Health Services Use and Costs in Individuals with Autism Spectrum Disorder in Germany: Results from a Survey in ASD Outpatient Clinics

Autism spectrum disorders (ASD) are associated with high services use, but European data on costs are scarce. Utilisation and annual costs of 385 individuals with ASD (aged 4-67 years; 18.2% females; 37.4% IQ < 85) from German outpatient clinics were assessed. Average annual costs per person were 3287 EUR, with psychiatric inpatient care (19.8%), pharmacotherapy (11.1%), and occupational therapy (11.1%) being the largest cost components. Females incurred higher costs than males (4864 EUR vs. 2936 EUR). In a regression model, female sex (Cost Ratio: 1.65), lower IQ (1.90), and Asperger syndrome (1.54) were associated with higher costs. In conclusion, ASD-related health costs are comparable to those of schizophrenia, thus underlining its public health relevance. Higher costs in females demand further research.

Barriers to Accessing Healthcare: Perspectives from Autistic Adults and Carers

Autistic adults have higher health needs compared to most, yet they continue to experience barriers to accessing appropriate healthcare. Presently, no qualitative research exists exploring these barriers which impact overall physical and mental health. We conducted a qualitative analysis in Victoria (Australia) of the perceived experiences of healthcare access for autistic adults (n = 9) and primary caregivers of autistic adults (n = 7). Specifically, a three-staged phenomenological approach was applied involving: (i) a communicative checklist, (ii) a health status survey and (iii) face-to-face interviews. Elements such as support, responsibilities and protective factors exhibited by caregivers, may impact healthcare access for autistic adults. Results indicate the need for further research exploring interdependent factors that impact healthcare access by caregivers, so evidence-based interventions can be developed to support caregivers in the future.

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.

Characterizing autistic traits in treatment-seeking young adults with substance use disorders

BACKGROUND AND OBJECTIVES

Recent work highlights an increase in the overlap of autism spectrum disorder (ASD) and substance use disorder (SUD). Little is known about the presence of ASD symptoms in SUD-treatment-seeking populations.

METHODS

The informant-rated Social Responsiveness Scale-2 (SRS-2) was completed at intake to an outpatient SUD clinic for youth aged 16-26 (N = 69). Comparisons were made between those with elevated SRS-2 scores on demographic, psychiatric, and substance use variables.

RESULTS

Parents of sixty-nine patients with SUD completed the SRS-2. Fourteen (20%) (average age 18.7 ± 2.5) had elevated SRS-2 Total T-scores (≥66) and 55 (average age 18.1 ± 2.8) had non-clinical SRS-2 Total T-scores. There were few differences between groups; however, those with elevated SRS-2 Total T-scores were more likely to have a stimulant use disorder (odds ratio [OR] = 7.59, 95% confidence interval [CI] = 0.77, 101.88; p = 0.05) or an opioid use disorder (OR = 5.02, 95% CI = 0.59, 43.27; p = 0.08) than patients with normal SRS-2 Total T-scores as well as alcohol use in the week prior to intake.

DISCUSSION AND CONCLUSIONS

A significant proportion of treatment-seeking SUD outpatients suffer from clinically elevated autistic traits. These findings highlight the importance of assessing for autistic traits in SUD treatment settings yet additional research is needed to determine if these findings are specific to the presence of ASD or secondary to sequelae of specific SUD presentations.

SCIENTIFIC SIGNIFICANCE

This study is, to our knowledge, the first to have examined the prevalence, morbidity, or clinical characteristics, associated with ASD symptoms in a SUD-specific population.

"Masking Is Life": Experiences of Masking in Autistic and Nonautistic Adults

Background

Autistic masking is an emerging research area, and so far, research has suggested that masking has a negative effect on autistic people. Masking relates to general social practices (such as identity management) and is often driven by stigma avoidance. Many nonautistic people also experience stigma that might drive them to suppress aspects of their identity. In this study, we investigate similarities and differences in experiences of masking in autistic and nonautistic people.

Methods

We conducted an online survey about experiences and views of masking in autistic people (n = 144), neurodivergent people without an autism diagnosis (n = 49), and neurotypical people (n = 45) recruited via social media. We used thematic analysis to analyze responses to open-ended items about masking, using an inductive approach, at a semantic level, with a critical realist paradigm.

Results

Thematic analysis revealed that some aspects of masking are shared across autistic and nonautistic people, such as utilizing mimicry of others as a social strategy or feeling exhausted from masking. All groups reported that masking made them feel disconnected from their true sense of identity and had a negative effect on them. Other aspects of masking seemed more specific to autistic people, such as sensory suppression, and masking leading to suicidal ideation.

Conclusions

Our findings suggest that many aspects of masking are experienced across different neurotypes and are likely related to outside perceptions of difference and stigma. It is likely that what we call "autistic masking" is similar to other forms of stigma management previously theorized. Some aspects of masking do seem more specific to the autistic neurotype (e.g., suppression of stimming) and should be explored further to provide support for autistic people recovering from the negative impact of masking.

Lay summary

Why was this study done?: Masking is the process of intentionally, or unintentionally, hiding aspects of yourself to avoid harm. Recent research has suggested that autistic people might mask a lot and that this can lead to long-term problems in mental health. At the moment, we do not know which parts of masking are specific to autistic people, and which parts might be experienced by others, especially other neurodivergent people who are not autistic, for example, people with attention-deficit hyperactivity disorder (ADHD).What was the purpose of this study?: The purpose of this study was to find out about masking in autistic and nonautistic people, to find out whether some parts of masking are specific to autistic people, or experienced by others.What did the researchers do?: We conducted an online survey about masking with three groups of people: autistic people, nonautistic people who have another neurodevelopmental or mental health diagnosis, such as dyslexia, ADHD, or depression, and nonautistic people who do not have any neurodevelopmental or mental health diagnoses. The survey included an open text box for people to write about their experiences of masking and their opinions about masking. We analyzed these responses using a method called "thematic analysis." This method helps us look for ideas that people commonly talk about in their answers.What were the results of this study?: We found out that autistic and nonautistic people think masking is very complicated and has a negative effect on them. Both autistic and nonautistic people said that masking made them exhausted and really unhappy and that it made them feel like people did not know the "real them." Only autistic people mentioned that masking sometimes makes them feel suicidal and that masking includes things that other groups did not mention (such as trying to hide being upset by sensory things such as loud noise).What do these findings add to what was already known?: Our findings suggest that some aspects of masking do not just affect autistic people (such as feeling like people do not know the real you), but other parts might be more unique to autistic people (such as hiding stims from other people).What are potential weaknesses in this study?: More women than men and nonbinary people took part, which means that we know more about women than other people. We also do not really know whether everyone in the nonautistic groups were really "not autistic." They could be autistic people who do not have a diagnosis, which might affect our results.How will these findings help autistic people now or in the future?: We hope our findings will help people to understand how masking affects autistic and nonautistic people. We also hope that people designing new studies will look at important things such as whether someone is autistic and nonbinary, or autistic and ADHD as these things might affect their experiences.

The sexual health, orientation, and activity of autistic adolescents and adults

Small studies suggest significant differences between autistic and nonautistic individuals regarding sexual orientation and behavior. We administered an anonymized, online survey to n = 2386 adults (n = 1183 autistic) aged 16-90 years to describe sexual activity, risk of sexually transmitted infections (STIs), and sexual orientation. Autistic individuals are less likely to report sexually activity or heterosexuality compared to nonautistic individuals, but more likely to self-report asexuality or an 'other' sexuality. Overall, autistic, and nonautistic groups did not differ in age of sexual activity onset or contraction of STIs. When evaluating sex differences, autistic males are uniquely more likely to be bisexual (compared to nonautistic males); conversely, autistic females are uniquely more likely to be homosexual (compared to nonautistic females). Thus, both autistic males and females may express a wider range of sexual orientations in different sex-specific patterns than general population peers. When comparing autistic males and females directly, females are more likely to have diverse sexual orientations (except for homosexuality) and engage in sexual activity, are less likely to identify as heterosexual, and have a lower mean age at which they first begin engaging in sexual activity. This is the largest study of sexual orientation of autistic adults. Sexual education and sexual health screenings of all children, adolescents, and adults (including autistic individuals) must remain priorities; healthcare professionals should use language that affirms a diversity of sexual orientations and supports autistic individuals who may have increased risks (affecting mental health, physical health, and healthcare quality) due to stress and discrimination from this intersectionality. LAY SUMMARY: This is the largest study on the sexual activity, orientation, and health of autistic adults. This study reaffirms that the majority of autistic adults are interested in sexual relationships and engage in sexual activity. Sexual education and sexual health screenings must remain a priority for all individuals, including those with autism; healthcare professionals should be aware that autistic patients may be more likely to identify as Lesbian, Gay, Bisexual, Trans, Queer, Asexual, and other identities not listed here (LGBTQA+) which may put them at greater risk of mental and physical health difficulties due to discrimination.

Health status of people with autism spectrum disorder

Purpose

The aim of this study is to determine what changes occur in the health status of people with autism spectrum disorder (ASD) compared to neurotypical controls.

Design/methodology/approach

The authors performed a comparative analysis of data collected from 72 subjects with ASD and 75 neurotypical controls aged 3–24 years using the Rochester Health Status Survey IV (RHSS-IV). A structured individual interview was conducted to compare the health status of subjects in Macedonia.

Findings

A majority of people with ASD take vitamins, supplements and use recommended drug therapies compared to the neurotypical population and experience a larger number of side effects (p = 0.000). Compared to people with neurotypical development, children with ASD have a higher prevalence of oral ulcers (31.9% vs 17.3%; p = 0.039), changes in neurological health status – epilepsy (19.4% vs 2.7%; p = 0.001) and ADD/ADHD (only persons with ASD-19.4%; p = 0.000); respiratory diseases – angina (30.5% vs 8%; p = 0.000), rhinitis and/or sinusitis (40.3% vs 17.3%; p = 0.02); changes in the gastrointestinal system – constipation (31.9% vs 10.6%; p = 0.02), intestinal inflammation (19.4% vs 8%; p = 0.043), permeable intestines (only persons with ASD – 13.9%; p = 0.000) and the presence of the fungus Candida albicans (19.4% vs 4%; p = 0.043); psychiatric disorders – sleep problems (only in people with ASD – 18%; p = 0.000) and tics (6.9% vs 2.6%; p = 0.25) and skin diseases – eczema/allergic skin rash (36.1% vs 18.7%; p = 0.02).

Originality/value

Many children with ASD have health problems. These findings support and complement the professional literature on their mutual causality.

COVID-19 risk: Adult Medicaid beneficiaries with autism, intellectual disability, and mental health conditions

LAY ABSTRACT

Autistic adults, adults with intellectual disability, and adults with other mental health conditions may have higher risk of contracting COVID-19 or experiencing more severe illness from COVID-19 if infected. We used data from Medicaid to look at whether autistic adults and other adults with intellectual disability and other mental health conditions were more likely to have risk factors for COVID-19, such as living in a residential facility, receiving services regularly in the home from outside caregivers, having had a long hospitalization, having had avoidable hospitalizations, and having high-risk health conditions. We found that autistic adults had higher odds of living in a residential facility, receiving in-home services from outside caregivers, having had an avoidable hospitalization, and having a high-risk health condition, compared to neurotypical adults without mental health conditions. Adults with intellectual disability had similar odds of having these conditions. Adults with other mental health conditions were also more likely to live in a residential facility, receive services from outside caregivers, and have had avoidable hospitalizations compared to the neurotypical population without mental health conditions. They had three times higher odds of having a high-risk health condition. High risk of COVID-19 among autistic adults and adults with intellectual disability and mental health conditions should be recognized by clinicians, and these groups should be prioritized for vaccine outreach.

Understanding the substance use of autistic adolescents and adults: a mixed-methods approach

BACKGROUND

Autistic individuals might be more likely to misuse substances than non-autistic individuals. Better understanding of these patterns can help clinicians identify strategies to reduce substance use, protecting physical and mental health. The aim of this study was to compare the experiences of substance use between autistic and non-autistic adolescents and adults.

METHODS

This study is a mixed-methods study, including both quantitative (closed-ended questions) and qualitative (one open-ended question) online assessments. Data were collected as part of a larger study, the Autism and Physical Health Survey, in which we administered an anonymised, online questionnaire to autistic and non-autistic individuals aged 16-90 years. In the present study, we investigated data on substance use or misuse, using two overlapping but separate samples from the survey (one sample with complete quantitative responses and one sample with complete qualitative responses). Binary measures of substance use were investigated using unadjusted and adjusted binomial logistic regression models. Content analysis was used to compare experiences of autistic and non-autistic adolescents and adults. We used Fisher's exact tests to assess differences in frequency of reporting particular qualitative themes and subthemes.

FINDINGS

Survey recruitment was done between Feb 7, 2018, and Aug 26, 2019. At the end of the recruitment, 3657 individuals had accessed the survey. After excluding duplicates as well as participants with missing or incomplete responses, we had data from 2386 participants (1183 autistic and 1203 non-autistic participants; 1571 female and 815 male participants) for the quantitative analyses and data from 919 participants (429 autistic and 490 non-autistic participants; 569 female and 350 male participants) in the qualitative analyses. The samples for the quantitative and qualitative analyses were predominantly composed of female individuals, White individuals, UK residents, and those without intellectual disability. Autistic individuals were less likely than non-autistic individuals to report consuming alcohol regularly (16·0% of autistic individuals vs 22·2% of non-autistic individuals; adjusted model: odds ratio [OR] 0·69, 95% CI 0·55-0·86; p=0·0022) or binge-drinking (3·8% vs 8·2%; adjusted model: OR 0·38, 0·26-0·56; p<0·0001). Autistic male participants were less likely than non-autistic male participants to report ever having smoked (50·8% of autistic male participants vs 64·6% of non-autistic male participants; adjusted OR 0·50; 0·32-0·76; p=0·0022) or ever using drugs (35·4% vs 52·7%; adjusted OR 0·53; 0·35-0·80; p=0·0022). Regarding our qualitative analyses, among participants who reported a specific motivation for drug use, compared with non-autistic individuals, autistic individuals were nearly nine times more likely to report using recreational substances to manage behaviour (OR 8·89, 2·05-81·12; p=0·0017) and more likely to report using recreational substances to manage mental health symptoms (OR 3·08, 1·18-9·08; p=0·032). Autistic individuals were also more likely to report vulnerability associated with substance use (OR 4·16, 1·90-10·05; p=0·00027), including childhood use of drugs and being forced or tricked into using drugs.

INTERPRETATION

Autistic individuals might be less likely than non-autistic individuals to report engaging in substance misuse. They also report using drugs to self-medicate. Clinicians should be aware of vulnerability linked to substance use among autistic patients and should work cooperatively with patients to effectively manage autistic and comorbid symptoms.

Demographic and psychological predictors of alcohol use and misuse in autistic adults

LAY ABSTRACT

Alcohol use and misuse are associated with a variety of negative physical, psychological and social consequences. The limited existing research on substance use including alcohol use in autistic adults has yielded mixed findings, with some studies concluding that autism reduces the likelihood of substance use and others suggesting that autism may increase an individual's risk for substance misuse. This study investigated demographic and psychological predictors of alcohol use and misuse in a sample of 237 autistic adults. An online survey was used to obtain data on demographic information, autistic traits, depression, generalised anxiety, social anxiety, mental well-being, social camouflaging and alcohol use. The sample was divided into three groups (non-drinkers, non-hazardous drinkers and hazardous drinkers) in order to investigate associations between alcohol use and demographic factors, autistic traits, mental health variables and social camouflaging. Our results demonstrated a U-shaped pattern among autistic adults, with non-drinkers and hazardous drinkers scoring higher than non-hazardous drinkers on levels of autistic traits, depression, generalised anxiety and social anxiety. Autistic non-drinkers were less likely to be male and had more autistic traits. Gender and level of autistic traits may be the most significant factors in predicting alcohol use in the autistic community.

Self-reported parkinsonism features in older autistic adults: A descriptive study

LAY ABSTRACT

Autistic adults without a suspected intellectual disability reported several motor features such as having tremors, and stiffness in one's legs which are considered to be part of a complex of motor features called parkinsonism. This so-called parkinsonism was remarkably prevalent in middle-aged and older autistic adults in two independent studies (Dutch study: 50-81 years, 183 males, 113 females, all adulthood diagnoses; the USA study: 50-83 years, 110 females, 109 males, majority adulthood diagnosis). Parkinsonism can be part of the progressive motor disease-Parkinson's disease. Therefore, it is important that future studies, including in-person neurological assessment, determine if (and if so, why) autistic adults who report these motor features are at increased risk for developing Parkinson's disease.

Autistic traits are associated with faster pace of aging: Evidence from the Dunedin study at age 45

Growing evidence indicates that the defining characteristics of autism spectrum disorder (ASD) are distributed throughout the general population; hence, understanding the correlates of aging in people with high autistic traits could shed light on ASD and aging. 915 members of the Dunedin longitudinal birth cohort completed a measure of autistic traits at age 45. A composite measure of the "pace of aging" was derived by tracking the decline in 19 biomarkers across ages 26, 32, 38, and 45 years. Facial age was also assessed. Reports of perceived health were collected from participants themselves, informants, and interviewers. Higher self-reported autistic traits significantly correlated with a faster pace of aging, older facial age, and poorer self-, informant-, and interviewer-rated health. After control for sex, SES and IQ, autistic traits were significantly associated with each variable: pace of aging (β = 0.09), facial age (β = 0.08), self- (β = -0.15), informant (β = -0.12), and interviewer-rated (β = -0.17) health. Autistic traits measured at age 45 are associated with faster aging. Participants with high autistic traits appear to be more vulnerable to poor health outcomes, as previously reported for those clinically diagnosed with ASD. Therefore, autistic traits may have important health implications. Replicating these findings in samples of autistic people is needed to identify the mechanism of their effect on aging and physical health to improve outcomes for those with ASD diagnoses or high autistic traits. LAY SUMMARY: The role that autistic traits have in relation to health outcomes has not been investigated. We looked at how physical health and aging (measured with self-reported questions and decline in multiple biological measures) were related to autistic traits (measured with a questionnaire, at age 45). We found that higher autistic traits were associated with poorer reports of physical health, and a faster pace of aging. This suggests that both those with autism and those with higher autistic traits may be more likely to experience poorer health outcomes.

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.

Types of dental procedures provided to adults with autism spectrum condition: A descriptive study

PURPOSE/AIM

To investigate demographic and systemic health characteristics, and the types of dental procedures performed for adults with autism that had sought care at a dental school.

MATERIALS AND METHODS

De-identified data were collected from the records of patients aged 18+ who have self-reported autism. Each patient's age, gender, BMI, mental health, heart disease, xerostomia, tobacco use, alcohol use, diabetes, use of drugs, seizures, and total number of medications, as well as the type and number of dental codes used in the care of that patient within each code category were included as variables.

RESULTS

The sample was composed by 244 patients. Mean age was 29.8 years (±12.3), 64.8% were males, and mean BMI was 29.9 (±8.1). Mental health condition was reported by 79.9%, heart disease by 25.4%, xerostomia by 21.7%, 20.9% reported using tobacco, 18.9% reported using alcohol, 14.8% reported having diabetes, 10.2% reported using drugs, and 3.7% reported having seizures. The median number of dental procedures per patient was nine, and exams, preventive, operative, and surgical procedures were the most common ones.

CONCLUSIONS

Adult patients with autism were overweight/obese young males. Most common dental procedures were exams, followed by preventive, operative, and surgical procedures.

Increased prevalence of non-communicable physical health conditions among autistic adults

LAY ABSTRACT

Previous research indicates autistic individuals die at a younger age than others and that this is possibly due in part to chronic physical health conditions. The present study used an anonymous, online survey to determine how common certain physical health conditions are among autistic adults, compared with non-autistic adults. We found autistic adults are more likely to develop heart conditions, lung conditions, and diabetes than non-autistic adults. Autistic females may be at higher risk of developing certain conditions (including respiratory conditions, asthma, and prediabetes) than autistic males. Finally, autistic individuals have increased health risks even when considering lifestyle factors (such as smoking, alcohol, and body mass index). This is still a relatively small study, and future research needs to confirm these findings and identify why these risks exist.

Development and psychometric testing of the AASPIRE Adult Autism Healthcare Provider Self-Efficacy Scale

LAY ABSTRACT

The adult healthcare system is ill-prepared to provide high-quality care to autistic adults. Lack of provider training may contribute to the problem, but there are few previously tested survey instruments to guide provider training efforts. Our objective was to develop and test a measure of healthcare providers' confidence (or "self-efficacy") in providing healthcare to autistic adults and to use it to better understand their training needs. We used a community-based participatory research (CBPR) approach, in partnership with academic researchers, autistic adults, supporters, and healthcare providers, throughout the project. We developed a one-page questionnaire and surveyed 143 primary care providers from eight primary care clinics in Oregon and California, United States. Preliminary testing of the AASPIRE Adult Autism Healthcare Provider Self-Efficacy Scale suggests that the measure is reliable and valid. Using this scale, we found only a minority of providers reported high confidence in communicating with patients (25%); performing physical exams or procedures (43%); accurately diagnosing and treating other medical issues (40%); helping patients stay calm and comfortable during visits (38%); identifying accommodation needs (14%); and making necessary accommodations (16%). While providers need training across all aspects of care related to autism in adulthood, interventions should pay particular attention to helping providers communicate with patients, and identify and make necessary accommodations. Future research is needed to further validate this scale and to understand how to meet providers' training needs most effectively.
