Significant regional inequalities in the prevalence of intellectual disability and trends from 1990 to 2019: a systematic analysis of GBD 2019

The influence of assistance in home-based exercise programmes for individuals with intellectual disabilities

BACKGROUND

Regular physical activity (PA) decreases the risk of comorbidities associated with a sedentary lifestyle in individuals with intellectual disabilities (IDs). They also may experience additional barriers that may prevent PA, including access, proper instruction and support. At-home PA programming is a feasible alternative to long-term adherence. This study aimed to determine (1) how an at-home DVD programme affects PA adherence and (2) the extent to which caregiver support influences PA.

METHODS

Thirty-one adolescent or adult-aged participants with mild or moderate ID were randomised into a DVD or control group exercise intervention. Participants were given autonomy to choose what type of PA modality from the intervention they would like to participate in. Caregiver support during the PA was also measured.

RESULTS

The two-way repeated-measures MANOVA demonstrated that the intervention DVD group was statistically significant, with a large effect size in PA minutes (P = 0.014, ηP2 = 0.236) and rate of perceived exertion (P = 0.002, ηP2 = 0.342) compared with the control group.

CONCLUSIONS

The findings demonstrated that using an adapted DVD increased PA minutes and the rate of perceived exertion without high levels of caregiver support.

Barriers and facilitators influencing implementation of care technology for people with intellectual disabilities: A cross-sectional study among care professionals

BACKGROUND

Implementation issues often hinder reaching the potential of care technology to improve daily lives of people with intellectual disabilities. We investigated barriers to and facilitators of implementing different technology modalities (app/social robot/sensor/domotics) in long-term care.

METHOD

Care professionals (N = 83) from 12 Dutch disability care organisations completed a customised measurement instrument for determinants of innovations (MIDI) questionnaire.

RESULTS

Out of 27 determinants, 20 were identified as facilitators and 16 as barriers. We highlight common barriers: few colleagues who work with the technology; no (awareness of) formal ratification of technology use; no arrangements regarding turnover of staff using the technology; unsettling organisational changes; technological defects and limited IT preconditions.

CONCLUSIONS

The results, which could be combined and compared across study sites, provide insight into which implementation determinants were already well addressed, and where there is ground to gain when implementing care technology in disability care organisations.

Comprehensive evaluation of the child with global developmental delays or intellectual disability

Global developmental delay (GDD) and intellectual disability (ID) are relatively common neurodevelopmental disorders that significantly impact affected children, their families, and society. The etiology of GDD/ID is notably diverse, encompassing both genetic and acquired factors. Although the precise cause of most GDD/ID cases remains unclear, an estimated half of all cases can be attributed to genetic factors. Thus, a detailed medical history and comprehensive physical examination remain pivotal for guiding diagnostic investigations into the underlying causes of GDD/ID. Advancements in genetic testing have supplanted traditional methods such as karyotyping and fluorescence in situ hybridization with chromosomal micro arrays, which are now the primary genetic tests for children with idiopathic GDD/ID. Moreover, the evaluation of Fragile X and Rett syndrome should be an integral component of initial diagnostic assessments. In recent years, whole-exome sequencing and whole-genome sequ-encing have emerged as important diagnostic tools for evaluating children with GDD/ID and have substantially enhanced the diagnostic yield rates. Gene therapy has emerged as a promising avenue and is poised to become a cornerstone in addressing various genetic developmental and epilepsy disorders. Early intervention facilitated by a proficient multidisciplinary team can markedly enhance the prognosis and outcomes of GDD/ID, particularly when parents or caregivers are actively engaged in the interventional process. This review discusses risk factors and common underlying causes, explores recent evidence and recommendations for genetic evaluation, and offers management strategies for children with GDD/ID.

The unmet need for mental health support among persons with disabilities in Somalia: Principal correlates and barriers to access

Disability and mental ill-health may be especially prevalent in Somalia, largely due to a protracted armed conflict and its consequent humanitarian crises. Little, if any, research to date, however, has simultaneously explored disability- and mental health-related factors in the Somali context. Using both descriptive and regression analytical techniques, we aimed to determine how increasing levels of functional impairment reported across different disability domains (i.e., visual, hearing and cognition), number of concomitant disabilities, and other empirically supported variables (such as employment and sex) are associated with the likelihood of self-identifying the need for mental health support among a sample (N = 1,355) of Somalis with disabilities, as well as identify the common barriers to such support. Despite most participants self-identifying a need for mental health support, only 15% were able to access it, with the most common barriers being the cost of services and the unavailability of local services. Being female, married, and having increasing levels of functional difficulty in the cognitive, mobility and self-care domains of disability were each significantly associated with an increased likelihood of the self-identified need for mental health support. This study's findings highlight potential points of prioritisation for mental health policy and programming in Somalia. A Somali version of this abstract can be found in the Supplementary Material.

The inequity of education, health and care plan provision for children and young people with intellectual and developmental disabilities

BACKGROUND

Children and young people (CYP) with intellectual and developmental disabilities (IDDs) have significant additional educational needs compared with the general population. In England, the government has established a system of education, health and care plans (EHCPs) to support children with special educational needs and disabilities, but disparities exist between the degree of need and the availability of support. We conducted a prospective UK national cohort study (IMAGINE) of children with rare pathogenic genomic variants, all of which are associated with IDD, to investigate associated neuropsychiatric risk. Subsequently, we obtained information from the UK's National Pupil Database on their educational progress through the state school system. We aimed to identify whether they had received EHCP provision and whether that support was associated with their family's socioeconomic status, region of domicile, ethnicity, sex, primary special educational needs (SEN) type, academic performance and mental health well-being.

METHODS

We recruited 2738 CYP from England into the IMAGINE study between 2014 and 2019. The educational histories of the participants (6-28 years old, mean ± standard deviation = 14 ± 4 years, 56% male) were obtained from the Department for Education's National Pupil Database in 2021. Educational data included attainment scores from the Early Year Foundation Stage (<5 years) to key stage 4 (15-16 years). Each family was assigned an index of multiple deprivation (IMD) score based on their home address postcode. Parents or carers rated their child's emotional and behavioural adjustment on the Strengths and Difficulties Questionnaire (SDQ). The association between receiving an EHCP and the child's IMD score, eligibility for free school meals, English region of domicile, ethnicity, sex, primary SEN type, academic attainment and SDQ score was investigated.

RESULTS

In this cohort, 78% of participants had received an EHCP. CYP living in the most deprived IMD deciles were substantially less likely to receive EHCP support than those in the least deprived decile, irrespective of their degree of intellectual developmental disability, academic performance or associated mental health problems. There were no sex differences. Children of Asian heritage were more likely to have been granted an EHCP than White children from equivalent IMD deciles. There were striking regional disparities. Participants living in London were significantly more likely to have been awarded an EHCP than participants living anywhere else in England, regardless of their IMD decile; those in the least deprived decile had almost 100% EHCP provision.

CONCLUSIONS

This study found evidence for nationwide regional inconsistencies in the awarding of EHCP to CYP with significant intellectual impairments of known genetic aetiology. Disparities in funds available to education authorities could be a contributory factor. EHCP support was potentially influenced by how strongly a parent advocates for their child.

Identifying victimization clusters across people with intellectual disabilities: A latent class analysis

BACKGROUND

Research has shown high rates of victimization among people with intellectual disabilities (ID), but victimization clusters have been barely explored.

OBJECTIVE

We address the gap by examining how reported victimization experiences are grouped into different classes and identifying differences in the characteristics of the individuals in each class.

METHODS

We conducted a cross-sectional self-report study with a sample of adults with an ID diagnosis (n = 260). We gathered data about the participants' victimization experiences and socio-demographics, and then subjected the data to latent class analysis (LCA).

RESULTS

Three different classes were detected: High victimization (n = 27, 10.4 %); medium victimization, low sexual (n = 97, 37.3 %); and low victimization (n = 136, 52.3 %). The results highlight the experiences of sexual and physical victimization among the high-victimization class, in which women are overrepresented, and physical victimization among the medium-victimization class. The study also found that experiences of assault and bias attacks occur to a varying extent across all three classes. The LCA and poly-victimization methods showed substantial agreement but also differences when identifying the most victimized participants. In addition, we detected significant differences between classes in gender, type of school attended, place of residence, legal incapacity, type of support needed, secondary disability and poly-victimization status.

CONCLUSION

We identified distinct underlying ingroup patterns of victimization and sociodemographic inter-class differences that contribute to a better understanding of victimization within the population in question. The results have prevention and intervention implications for caregivers and providers of services for people with ID.

Evaluation of Individuals with Non-Syndromic Global Developmental Delay and Intellectual Disability

Global Developmental Delay (GDD) and Intellectual Disability (ID) are two of the most common presentations encountered by physicians taking care of children. GDD/ID is classified into non-syndromic GDD/ID, where GDD/ID is the sole evident clinical feature, or syndromic GDD/ID, where there are additional clinical features or co-morbidities present. Careful evaluation of children with GDD and ID, starting with detailed history followed by a thorough examination, remain the cornerstone for etiologic diagnosis. However, when initial history and examination fail to identify a probable underlying etiology, further genetic testing is warranted. In recent years, genetic testing has been shown to be the single most important diagnostic modality for clinicians evaluating children with non-syndromic GDD/ID. In this review, we discuss different genetic testing currently available, review common underlying copy-number variants and molecular pathways, explore the recent evidence and recommendations for genetic evaluation and discuss an approach to the diagnosis and management of children with non-syndromic GDD and ID.
