Autistic adult outcomes on weight and body mass index: a large-scale online study

Exploring Collaborative Efforts Toward Promoting Better Eating Habits among Autistic Children in the United Arab Emirates

According to the principle of duty of care, adults in the lives of children with disabilities such as autistic children are expected to promote their development. The Nutbeam's health literacy model was adopted to explore the efforts of special education teachers and parents toward promoting better eating habits among autistic children in the United Arab Emirates (UAE). Twenty-one participants, comprising fifteen special education teachers and six parents with autistic children, were examined in this study. The results indicated that some special education teachers' and parents' limited understanding of unhealthy food might impact the development of autistic children. Furthermore, the findings also highlight the lack of collaboration and communication between teachers regarding the nutrition and healthy living of autistic children. The findings have practical consequences, such as urging UAE health policymakers to provide professional development for special education instructors and parents of autistic children.

The Potential Usefulness of the Expanded Carrier Screening to Identify Hereditary Genetic Diseases: A Case Report from Real-World Data

Expanded carrier screening (ECS) means a comprehensive genetic analysis to evaluate an individual's carrier status. ECS is becoming more frequently used, thanks to the availability of techniques such as next generation sequencing (NGS) and array comparative genomic hybridization (aCGH), allowing for extensive genome-scale analyses. Here, we report the case of a couple who underwent ECS for a case of autism spectrum disorder in the male partner family. aCGH and whole-exome sequencing (WES) were performed in the couple. aCGH analysis identified in the female partner two deletions involving genes associated to behavioral and neurodevelopment disorders. No clinically relevant alterations were identified in the husband. Interestingly, WES analysis identified in the male partner a pathogenic variant in the LPL gene that is emerging as a novel candidate gene for autism. This case shows that ECS may be useful in clinical contexts, especially when both the partners are analyzed before conception, thus allowing the estimation of their risk to transmit an inherited condition. On the other side, there are several concerns related to possible incidental findings and difficult-to-interpret results. Once these limits are defined by the establishment of specific guidelines, ECS may have a greater diffusion.

Dietary recommendations to customize canteen menus according to the nutritional and sensory needs of individuals with autism spectrum disorder

Individuals with autism spectrum disorders (ASD) are often characterized by food-selectivity, food-neophobia and a marked preference for mild flavor, semi-liquid foods with pale colors. Therefore, they adopt a monotonous dietary pattern, and they prefer ultra-processed food, leading to a high risk of developing malnutrition. In Italy, where 75,072 individuals are diagnosed with ASD, center-based services play a crucial role in their daily management. Despite the centrality of nutrition in maintaining a good state of health, even more for vulnerable subjects, no validated protocol at collective catering level has been developed yet. The manuscript presents customized dietary recommendations aimed at managing the meals for individuals with ASD at collective catering service, derived from a non-systematic literature review exploring food behaviors and nutritional needs in individuals with ASD. Simple practical tips for mealtimes, such as eating together, proper seating, lighting, smell control, presenting food in a simple manner and using the same type of tableware at each meal, to meet the needs of individuals with ASD, were described. The proposal could represent a starting point in developing official guidelines aimed at ASD individuals, in collective catering service.Level of Evidence: Level V.

Accessibility of nutritional services for children with autism spectrum disorder in the United Arab Emirates: Insights from special education teachers and parents

BACKGROUND

Goal 2 of United Nation's Sustainable Development Goals exhorts countries to provide guidelines on better nutrition for all children. In response, the United Arab Emirates (UAE) government designed a national nutrition framework to encourage better eating habits. However, large body of literature has reported that children with ASD are at high risks of malnutrition and poor eating habits. Yet, in the UAE and other contexts, there is limited research on accessibility of nutritional services to adults in the lives of children with ASD.

AIMS

As parents and teachers spend the most time with children with ASD, this study sought to understand their perceptions of the availability of nutritional services for such children in the UAE.

METHOD AND PROCEDURES

Penchansky and Thomas' (1981) health access theory served as the theoretical framework; its five tenets (geography, finance, accommodation, resources and acceptability) informed the design of a semi-structured interview guide. Data were collected from 21 participants, comprising 6 parents and 15 teachers of children with ASD.

OUTCOMES AND RESULTS

Thematic analysis revealed that participants perceived accommodation, acceptability, and human resource availability as barriers to accessibility. However, geographical and financial accessibility were not identified as challenges.

CONCLUSIONS AND IMPLICATIONS

The study calls for health policymakers to formalise nutritional services as an integrated part of the UAE health system, while also extending services to children with ASD.

CONTRIBUTION

This study makes a substantial contribution to the literature. First, it addresses the needs for nutritional services for children with ASD. There is a limited body of knowledge on whether children with ASD have access to the requisite nutrition for development This study sheds light on an area that has received limited scholarly insight. Second, it adds to the usage of health access theory in studies on nutritional services for children with ASD.

Assessment of Feeding Behaviors and Parents' Frustrations of Children with Autism Spectrum Disorder in Lebanon: A Case-Control Study

Children with autism spectrum disorder (ASD) exhibit restrictive and repetitive behaviors that affect their eating habits. The purpose of this study is to identify the behavioral feeding problems and eating habits among ASD children compared to typically developed (TD) children age/gender-matched controls, along with their parents'/caregivers' strategies for dealing with them. It included 43 ASD children and 43 TD children aged two to eleven years. The analysis was performed based on two valid questionnaires: the Behavior Pediatrics Feeding Assessment Scale (BPFA) and "My Child Eating Habits" (MCEH). The BPFA and MCEH scores conceded three manifestations that fall into food selectivity and problematic mealtime behavior in both groups of children. Compared to TD children, children with ASD exhibited higher BPFA scores, which indicated food-related behavioral and skill-based problems (p = 0.004). Children with ASD were less likely to consume fruits, vegetables, and milk than TD children, which may lead to nutritional deficiencies (p = 0.003, p = 0.003, and p = 0.010, respectively). Parents of ASD children were concerned about their behavioral problems and expressed their intention of an early intervention. These findings highlight the importance of nutritional clinical routines that incorporate the evaluation of the nutritional status and feeding behaviors of ASD children.

Nutritional needs of children with disabilities in the UAE: understanding predictors and mediators of nutritional knowledge and practices

Background

There is a high estimated prevalence of obesity and poor eating habits among children with disabilities. Unfortunately, the extent of parental and teachers’ awareness of the dietary needs and nutritional requirements of children with disabilities has been understudied. This study aims to explore the predictors and mediators of nutritional knowledge and practices among parents and teachers of children with disabilities in the United Arab Emirates (UAE) using Nutbeam’s hierarchical health literacy model as a framework to test three hypotheses.

Methods

A total of 149 parents and teachers were recruited from rehabilitation centres in two of the seven Emirates in the UAE. The revised Food and Nutritional Literacy Scale (FNLIT) was used for data collection. The revised scale was validated and its reliability was assessed using SPSS and AMOS version 28 to compute exploratory factor analysis and structural equation modelling (confirmatory factor analysis and path analysis), respectively.

Results

The results confirmed a four-factor structure for FNLIT, and all three hypotheses were supported by the study findings. We confirmed a relationship between understanding and practical nutritional skills (Hypothesis I), and found that two practical nutritional skills, functional and interactive, combined to predict the understanding of nutritional needs of children with disabilities (Hypothesis II). Hypothesis III was partially supported in that participant type mediated the relationship between functional, interactive, and understanding factors. The convergent and discriminant validities of the scale were confirmed, and path analysis showed the ability of practical skills to predict knowledge.

Conclusion

The study concludes on the need for public education on nutritional needs as well as developing the capacity of teachers and parents to implement appropriate eating programmes for children with disabilities.

Different pathways, same goals: A large-scale qualitative study of autistic and non-autistic patient-generated definitions of recovery from an eating disorder

BACKGROUND

Definitions of recovery from an eating disorder (ED) have generally been formulated around clinical conceptualisations, rather than based on the views of patients. This paper therefore asked those with lived experience of ED for their own definitions of recovery.

METHOD

Data were collected as part of an online study looking at EDs, autism and relationships. About 173 participants identified as recovered from ED and gave free-response definitions of recovery. Responses were subject to thematic analysis.

RESULTS

Seven major themes were identified: Weight restoration, lack of ED behaviours, thoughts and behaviours, cognitions, emotional responses, getting on with life, and ongoing challenges.

CONCLUSIONS

Many definitions of recovery given by those who have lived experience of ED echoed those used by clinicians and researchers. There were also points of divergence around the ongoing challenges of recovery. Our findings highlight the need for continuing support post-weight restoration to facilitate the successful long-term recovery for those with ED.

Mild Hypophagia and Associated Changes in Feeding-Related Gene Expression and c-Fos Immunoreactivity in Adult Male Rats with Sodium Valproate-Induced Autism

A core yet understudied symptom of autism is aberrant eating behaviour, including extremely narrow food preferences. Autistic individuals often refuse to eat despite hunger unless preferred food is given. We hypothesised that, apart from aberrant preference, underfeeding stems from abnormal hunger processing. Utilising an adult male VPA rat, a model of autism, we examined intake of ‘bland’ chow in animals maintained on this diet continuously, eating this food after fasting and after both food and water deprivation. We assessed body weight in adulthood to determine whether lower feeding led to slower growth. Since food intake is highly regulated by brain processes, we looked into the activation (c-Fos immunoreactivity) of central sites controlling appetite in animals subjected to food deprivation vs. fed ad libitum. Expression of genes involved in food intake in the hypothalamus and brain stem, regions responsible for energy balance, was measured in deprived vs. sated animals. We performed our analyses on VPAs and age-matched healthy controls. We found that VPAs ate less of the ‘bland’ chow when fed ad libitum and after deprivation than controls did. Their body weight increased more slowly than that of controls when maintained on the ‘bland’ food. While hungry controls had lower c-Fos IR in key feeding-related areas than their ad libitum-fed counterparts, in hungry VPAs c-Fos was unchanged or elevated compared to the fed ones. The lack of changes in expression of feeding-related genes upon deprivation in VPAs was in contrast to several transcripts affected by fasting in healthy controls. We conclude that hunger processing is dysregulated in the VPA rat.

COVID-19 and UK family carers: policy implications

Informal (unpaid) carers are an integral part of all societies and the health and social care systems in the UK depend on them. Despite the valuable contributions and key worker status of informal carers, their lived experiences, wellbeing, and needs have been neglected during the COVID-19 pandemic. In this Health Policy, we bring together a broad range of clinicians, researchers, and people with lived experience as informal carers to share their thoughts on the impact of the COVID-19 pandemic on UK carers, many of whom have felt abandoned as services closed. We focus on the carers of children and young people and adults and older adults with mental health diagnoses, and carers of people with intellectual disability or neurodevelopmental conditions across different care settings over the lifespan. We provide policy recommendations with the aim of improving outcomes for all carers.

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

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

Use of allied-health services and medication among adults with ASD in Latin America

ASD is a neurodevelopmental disorder that affects people across the entire lifespan, yet most of the research identifying the health and medical needs for autistic individuals have been among minors. As individuals with ASD transition to emerging adulthood, the services, already limited, become less available. This study aimed to identify the use of services for Latin American adults on the spectrum. We surveyed 295 caregivers of adults with ASD from six Latin American countries. Comparing the results for all the possible services observed in this study, the adults in our sample were primarily underserved: 84.4%-95.9% were receiving zero hours per week, 3.7%-12.9% 1%-10 h, 0%-1.7% 11-20, and only 0%-1% above 20 h of services. Almost half of the sample used medication, and neurologists were the most consulted health providers. Next to inexistent health care usage in Latin American adults with ASD highlights socioeconomic and health disparities in service provision for ASD in the region. The lack of services places adults with ASD in Latin America at a higher risk of worse symptom severity than autistic adults from regions with broader access to services. LAY SUMMARY: This study aimed to identify the quantity of services received by adults with autism in Latin America. Most of our sample was not receiving health services yet almost half had access to medication. This could mean that adults with autism in Latin America are at higher risk for poorer health.

Autistic Traits Mediate Reductions in Social Attention in Adults with Anorexia Nervosa

Anorexia nervosa (AN) is associated with difficulties in social and emotional functioning. A significant proportion of individuals with AN show autistic traits, which may influence social attention. This study examined attention to faces and facial features in AN, recovered AN (REC), and healthy controls, as well as relationships with comorbid psychopathology. One hundred and forty-eight participants' eye movements were tracked while watching a naturalistic social scene. Anxiety, depression, alexithymia, and autistic traits were assessed via self-report questionnaires. Participants with AN spent significantly less time looking at faces compared to REC and controls; patterns of attention to individual facial features did not differ across groups. Autistic traits mediated the relationship between group and time spent looking at faces.

Comparison of gut microbiota between adults with autism spectrum disorder and obese adults

Background

Autism spectrum disorder (ASD) and obesity are serious global public health problems. Studies have shown that ASD children are at a higher risk of obesity than the general population. To investigate the gut microbe characteristics of adults ASD and obese adults, we compared the gut microbiota of adults with ASD to obese adults.

Methods

The fecal samples were collected from 21 adult patients with ASD and 21 obese adults, and V3–V4 regions of 16S rRNA genes were sequenced by high-throughput DNA sequencing. The gut microbiota of adults with ASD and obese adults was compared.

Results

We observed the proportion of Firmicutes/Bacteroidetes in ASD was significantly increased, with families Lachnospiraceae and Ruminococcaceae significantly enriched in adult ASD. Eighteen genera, including Lachnospiracea incertae sedis, Ruminococcus, Blautia, and Holdemanella were significantly increased in adult ASD, whereas Megamonas and Fusobacterium were significantly increased in obesity. At the species level, we found six species enriched in ASD and three species enriched in obesity, including Phascolarctobacterium succinatuten producing propionate. Dialister succinatiphilus may be as a biomarker for predicting obesity, as well as Prevotella copri may be a common-owned pathogens of ASD and obesity.

Conclusions

Some conflicting results have been reported in microbiota studies of ASD, which may be related to age and obesity. Thus, the body mass index should be evaluated before analyzing the gut microbiota of patients with ASD, as obesity is prevalent in these individuals and gut microbiota is severally affected by obesity.

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

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

Exploring Self-Reported Eating Disorder Symptoms in Autistic Men

Background

Although research suggests a relationship between restrictive eating disorders (EDs) and autism, there is a lack of research in this area from the perspective of autistic men. Our aim was to explore whether ED symptoms are heightened in autistic men compared with nonautistic men.

Methods

We recruited 103 autistic and nonautistic participants through an online study. We assessed ED symptoms, autistic features, anxiety, depression, and body mass index (BMI) using self-report measures.

Results

Autistic men (n = 54) exhibited significantly higher levels of ED symptoms in the areas of eating (p < 0.001), shape (p = 0.005), and weight (p = 0.001) concerns, and the global score (p = 0.046) than nonautistic men (n = 49). However, autistic men scored significantly lower in the area of dietary restraint (p = 0.032). Global ED scores did not correlate with autistic traits, but did correlate with anxiety (p < 0.001) and BMI (p < 0.001) in the autistic group.

Conclusions

This exploratory study suggests that heightened ED symptoms in autistic men may be related to heightened levels of anxiety and higher BMIs, rather than autistic traits. It also highlights that autistic men may experience symptoms not relating to dietary restraint. Future research should consider further exploring the relationship between anxiety, BMI, and disordered eating in autism.

Lay Summary

Why was this study done?: There is a lot of interest in the relationship between autism and eating disorders (EDs). Research suggests that as many as one in four people with anorexia could be autistic. However, most research has been done (1) on women and (2) looking at autistic traits in women with anorexia. There is less research looking at the relationship from the perspective (1) of men and (2) looking at ED symptoms in autistic people.What was the purpose of this study?: We aimed to explore whether autistic men experience more ED symptoms than nonautistic men.What did the researchers do?: This was an online study. We asked participants to fill out self-report measures of autistic traits and ED symptoms. We also asked participants to self-report whether they were autistic, and whether they had been previously diagnosed with an ED. We included 54 autistic men and 49 nonautistic men.What were the results of the study?: We found that although autistic men did experience higher levels of ED symptoms than nonautistic men, this did not appear to be related to autistic traits. Instead ED symptoms were related to anxiety and higher rates of being overweight or obese. In addition, autistic men in fact experienced significantly lower levels of ED symptoms associated with dietary restraint than nonautistic men.What do these findings add to what was already known?: Our findings reflect some previous research findings that ED symptoms may be heightened in autistic people. They also suggest that these symptoms are related to higher levels of anxiety or body mass indexes (BMIs) in autistic people, rather than autistic traits themselves. Also, most previous research has focused on symptoms of restraint in EDs and autism, for example, limiting the amount you eat or not eating certain foods. In our study, restraint was not found to be heightened, suggesting that focusing on restraint symptoms might be less relevant to autistic men.What are potential weaknesses in the study?: One key weakness is our use of self-report measures, particularly asking participants to self-report their autism diagnosis. An additional limitation is the small sample size, which makes it hard to generalize findings.How will these findings help autistic adults now or in the future?: More research is needed to understand the relationship between anxiety, BMI, autism, and ED symptoms. Our findings could help our understanding of disordered eating in autistic adults as they suggest we need to pay more attention to autistic adults experiencing ED symptoms that are not related to dietary restriction, such as binge eating.
