Background
People with Down syndrome (DS) may exhibit several musculoskeletal disorders, including alterations in muscle tone and activation. Strength training could mitigate the loss of muscle strength and, therefore, improve strength values in this population. Additionally, it may influence health-related outcomes such as physical function, body composition and biochemical markers.
Objective
This systematic review and meta-analysis of randomised controlled trials (RCTs) aimed to analyse the characteristics and effects of strength training in people with DS.
Methods
A search was conducted from inception to 22 April 2025. The methodological quality of the included RCTs was assessed using the 15-item Tool for the assEssment of Study qualiTy and reporting in EXercise (TESTEX). In addition, the risk of bias was assessed using the Cochrane's risk of bias 2 (RoB2).
Results
A total of 10 RCTs (n = 233 participants) were included in the systematic review, of which three (n = 111 participants) could be meta-analysed. The pooled effect showed statistically significant benefits for upper (mean difference [MD] = 5.66 kg, 95% CI 2.42–8.91) and lower (MD = 20.43 kg, 95% CI 1.76–39.10) body strength. The TESTEX scores for most RCTs ranged from 3 to 12 points. The risk of bias analysis indicated that eight RCTs had a low risk of bias, whereas the remaining studies were classified as high risk.
Conclusion
Strength training may significantly improve muscle strength in people with DS. However, further research is needed to assess the long-term effects on physical function, body composition and biochemical markers.
背景：唐氏综合征（DS）患者可能表现出几种肌肉骨骼疾病，包括肌肉张力和激活的改变。力量训练可以减轻肌肉力量的损失，从而提高该人群的力量值。此外，它还可能影响与健康相关的结果，如身体功能、身体成分和生化指标。目的：对随机对照试验（RCTs）进行系统回顾和荟萃分析，旨在分析退行性椎体滑移患者力量训练的特点和效果。方法：从开始到2025年4月22日进行检索。采用15项研究质量评估工具（TESTEX）评估纳入的随机对照试验的方法学质量。此外，采用Cochrane's risk of bias 2 （RoB2）评估偏倚风险。结果：系统评价共纳入10项rct （n = 233名受试者），其中3项（n = 111名受试者）可进行meta分析。综合效应显示，较高（平均差异[MD] = 5.66 kg, 95% CI 2.42-8.91）和较低（MD = 20.43 kg, 95% CI 1.76-39.10）的身体力量有统计学意义的益处。大多数随机对照试验的TESTEX分数在3到12分之间。偏倚风险分析显示，8项rct为低偏倚风险，其余研究为高风险。结论：力量训练可显著提高退行性椎体滑移患者的肌力。然而，需要进一步的研究来评估对身体功能、身体成分和生化指标的长期影响。

Background
Children with Down syndrome (DS) have an increased frequency of co-occurring medical complications compared to the typically developing population; however, incidence rates of co-occurring medical conditions in a large paediatric population-based study are limited. The goal of this study was to further investigate the frequencies of concomitant medical conditions, as well as newborn complications in children with DS.
Methods
This is a retrospective, large cohort review of children with DS (n = 2321) receiving care at a referral centre specialising in DS to identify common patterns of co-occurring conditions in children and young adults with DS. Participants from birth to 24 years of age received care from the Anna and John J. Sie Center for Down Syndrome at Children's Hopsital Colorado, which serves 88% of the State of Colorado’s paediatric population with DS. Records reviewed included demographics, birth history, and medical conditions of each patient.
Results
Neonatal complications requiring admission to the neonatal intensive care unit (NICU) were present in 80.0% of the population. Complications leading to these admissions include oxygen requirement (53.7%), feeding problems (49.7%), respiratory distress syndrome (14.7%), and persistent pulmonary hypertension of the newborn (12.6%). Incidence of medical complications for children and young adults with DS includes obstructive sleep apnea (56.8%), cardiac defect requiring surgical repair (48.9%), feeding problems (42.3%), and dysphagia (26.2%). Recently identified co-occurring conditions lacking in the literature, such as keratoconus (3.6%) and Wolff–Parkinson–White syndrome (3.4%), are also reported. Testing, labs and procedures were also common amongst children to meet American Academy of Pediatrics (AAP) DS Guidelines.
Conclusion
Children with DS have unique phenotypic clinical patterns of co-occurring conditions and medical complications. Some conditions present clinically in the neonatal period and require close monitoring and anticipation for a higher level of care for newborns with DS. Our results, using a large sample of over 2300 patients, provide information to improve evidence-based early identification and timely intervention for children and young adults with DS.

Background
People with intellectual disabilities often use psychotropic medications. Recognising side effects in this population can be challenging while they can negatively impact the quality of life. An accurate screening instrument is crucial to identify side effects of psychotropic medication in people with intellectual disabilities. For this purpose, the Matson Evaluation of Drug Side Effects (MEDS) is the most reliable and well-researched instrument. We translated the MEDS into Dutch, considering that the Dutch version of the MEDS must be accurate and aligned with its intended meaning, avoiding multiple interpretations; this study aimed to assess its intrarater and interrater reliabilities in people with intellectual disabilities using psychotropic medication.
Methods
A certified medical translation agency performed translation and back-translation of the MEDS. Two researchers administered the MEDS three times on the same day. Participants were people with intellectual disabilities using psychotropic medication. Demographic and medical data were collected via questionnaires. Scoring and calculation of total domain scores, severity domain scores, duration domain scores and composite scale scores followed the MEDS manual. Intraclass correlation coefficients (ICC) and 95% confidence intervals of these scores were used to assess intrarater and interrater reliabilities.
Results
The study sample included 40 adults with intellectual disabilities. Intrarater reliability was good to excellent for total domain scores (ICCs ranging from 0.873 to 1.000) and excellent for the total composite scale score (ICC = 0.945). Interrater reliability was moderate to excellent for total domain scores (ICCs ranging from 0.713 to 0.922) and good for the total composite scale score (ICC = 0.894).
Conclusions
This study demonstrated moderate to excellent intrarater and interrater reliabilities for the Dutch version of the MEDS. This confirms its potential as a valuable instrument for clinicians to identify and monitor side effects in people with intellectual disabilities using psychotropic medication. We recommend the use of the Dutch version of the MEDS in both Dutch clinical practice and research for this purpose.

Background
Adults with intellectual disabilities (ID) and autism spectrum disorders (ASD) have a higher risk of fracture; yet little is known about key fracture characteristics that may inform fracture prevention efforts. The objective was to describe the reported activities that lead to a fracture event, the energy of fractures (e.g., low-energy such as fragility fractures and high-energy such as fractures from a motor vehicle accident) and the location of fractures for adults with ID and ASD.
Methods
In this retrospective cohort study from the United States, medical records from a single clinical site were abstracted to gather information on fracture characteristics (i.e., fracture location, energy of fracture and activities that lead to the fracture event) from adults ≥ 18 years old with intellectual disabilities (ID) and/or autism spectrum disorders (ASD) that sustained ≥ 1 fracture between 1 November 2012 and 2 November 2021. The fracture characteristics were described for the entire cohort and by the following subgroups: ID only, ASD only and ID + ASD.
Results
Of the 126 adults with ID and/or ASD, there were a total of 147 fractures for analysis: 84.9% had one fracture, 13.5% had two fractures and 1.6% had three fractures. For the entire cohort, 32.0% were defined as high-energy fractures, but this varied by subgroup: 24.1% for ID only (n = 69 participants, n = 87 fractures), 50.0% for ASD only (n = 35 participants, n = 36 fractures) and 33.3% for ID + ASD (n = 22 participants, n = 24 fractures). The remaining fractures were defined as low-energy or unknown energy. The most common activities that lead to a fracture event were broadly categorised as ‘low-impact falls, unwitnessed falls, transfers’ for ID only (47.1%), ASD only (27.8%) and ID + ASD (41.7%). The most common skeletal region of fractures occurred in the lower extremities for ID only (42.5%) and ID + ASD (50.0%) and in the upper extremities for ASD only (33.3%).
Conclusions
Despite the age being 18 years and older (i.e., not exclusively elderly), most fractures were considered to be low-energy and occurred in the extremities, but this varied by subgroup. This study identified the activities that led to a fracture event, which may inform fracture prevention efforts such as adjunct therapies.

Background
The estimation of physical activity (PA) and sedentary behaviour with accelerometers is typically based on the relationship between accelerometer output and metabolic equivalents (METs)—an index of PA intensity. But for adults with Down syndrome (DS), PA intensity may be better reflected in the percent oxygen uptake reserve (%VO2Reserve), as it accounts for their lower aerobic fitness. This study examined if the relationship between accelerometer output and METs or %VO2Reserve across various PAs and sedentary behaviours differs between adults with and without DS.
Methods
Forty-one adults with DS (age 35 ± 9 years; 18 women) and 41 adults without DS (age 24 ± 5 years; 18 women) performed 17 tasks of varying intensity. We estimated aerobic fitness with a submaximal treadmill test. We measured oxygen uptake with portable calorimetry and expressed it as METs and %VO2Reserve. Output from triaxial accelerometers on the nondominant hip and wrist was determined as Vector Magnitude (VM). We used multilevel modelling to evaluate the relationships of METs or %VO2Reserve with VM, controlling for body mass index (BMI) and age.
Results
For the hip accelerometer, VM and the group-by-VM interaction significantly predicted METs (p < 0.001; conditional R2 = 0.82), but between-group differences were small. For the wrist accelerometer, VM and age significantly predicted METs (p < 0.035; conditional R2 = 0.76). For both the hip and the wrist accelerometer, VM, the group-by-VM interaction and BMI significantly predicted %VO2Reserve (p ≤ 0.047; conditional R2 = 0.82 and 0.74, respectively). Between-group differences in the response to VM were larger for VO2Reserve than METs models.
Conclusion
The relationship between accelerometer output and %VO2Reserve across PAs and sedentary behaviours is different between adults with and without DS. Calibrating accelerometer output against %VO2Reserve may be preferable to METs.

Background
The diagnosis of an intellectual disability is suggested to have particularly stigmatising connotations, particularly within the criminal justice system (CJS). This paper aims to synthesise qualitative studies investigating the attitudes of CJS professionals to people with intellectual disabilities (PWID), specifically offenders with intellectual disabilities, and to appraise their methodological quality.
Methods
A systematic search was conducted using PsychINFO, Web of Science, MEDLINE, EMBASE, CINAHL Complete and EThOS databases. Articles were screened for inclusion by title, abstract and full text to ensure predefined inclusion criteria were met. Individual study quality was rated using the 10-item Critical Appraisal Skills Programme (CASP) checklist, with the addition of an eleventh item to capture included studies' theoretical underpinnings and optimise the value of the quality appraisal. Thematic synthesis was then used to explore and synthesise the findings of the included studies.
Results
Ten papers were included in the review, spanning 766 participants. Studies included utilised mixed methods surveys (n = 3), qualitative surveys (n = 1), semistructured interviews (n = 3), semistructured focus groups (n = 1), unstructured interviews (n = 1) and secondary analysis of previously collected research data (n = 1). Methodological quality was broadly of a high standard; however, all included papers failed to reflect on the relationship between the researchers and participants. Five themes were identified: conflating diagnoses, perceptions of PWID as offenders, procedural issues affecting PWID, development and maintenance of perceptions, and impact of training.
Conclusions
This review highlights pervasive negative perceptions of offenders with intellectual disabilities within CJS staff groups. Clinician- and system-level factors are considered in the development and maintenance of such attitudes and suggestions made for improving CJS staff perceptions and knowledge of offenders with intellectual disabilities.

Background
Challenging behaviours such as self-injury and aggression are prevalent among individuals with intellectual disability (ID), significantly impacting quality of life. Cardiofaciocutaneous syndrome (CFCS), a rare multisystem genetic disorder caused by variants in the BRAF, MAP2K1, MAP2K2, or KRAS genes, commonly presents with ID and other neurobehavioural features. To inform effective clinical management, we aimed to characterise and quantify challenging and repetitive behaviours in CFCS, identify functions that may maintain the behaviours, and examine associations with genotype and neurological comorbidities.
Methods
In this cross-sectional cohort study, caregivers of 61 individuals with CFCS (mean age = 14.2 years; 61% female) completed an electronic survey to capture information regarding demographics, adaptive skills, and neurological history. Genotype was determined from molecular genetic testing results. The frequency, severity, topography, and function of challenging behaviours were assessed with behaviour questionnaires validated for children and adults with developmental disabilities. We evaluated trends using descriptive analyses and examined mean differences across age, genotype, and neurological variables.
Results
The cohort consisted primarily of individuals with BRAF variants (62%), followed by MAP2K1 (28%) and MAP2K2 (10%) variants. Prevalence of challenging behaviour was high (77%), and self-injurious and aggressive behaviours were most frequent and severe among adolescents with CFCS relative to younger children or adults. Escape (seeking to avoid an unwanted situation or task) was the most endorsed behavioural function to maintain self-injurious and aggressive/destructive behaviours. BRAF gene variants were associated with the most frequent and variable challenging behaviours, followed by MAP2K1, and then MAP2K2. Challenging and repetitive behaviours were most prevalent among individuals with moderate adaptive functioning, clinically significant sleep disturbance, higher levels of pain interference, and more substantial sensory modulation differences. Individuals with epilepsy also exhibited more frequent repetitive and self-injurious behaviours.
Conclusion
Caregivers reported a high prevalence of challenging behaviours among individuals with CFCS, especially in late childhood and adolescence. Therapeutic approach

Background
Hearing and visual impairments are common in individuals with Down syndrome (DS), yet it remains unclear whether sensory impairments are associated with cognitive and behavioural functioning such as language, memory and socialisation. This literature review examines those associations.
Methods
A scoping review of four databases was conducted to examine associations between sensory impairments and cognitive or behavioural outcomes in individuals with DS. Study evidence was assessed based on design, sample size, assessment modalities and statistical significance.
Results
Of 1471 studies screened, 38 met inclusion criteria. Hearing impairments were associated with delays in language and motor development during infancy, lower overall cognitive ability and social communication difficulties in childhood and reduced adaptive functioning and intellectual decline in adulthood. Visual impairments were linked to learning difficulties in childhood and to declines in adaptive behaviour, visual-motor integration and cognitive performance in adulthood. Subdomains of cognitive functioning such as memory, reasoning or processing speed were not reported for adults.
Conclusion
Uncorrected hearing and visual impairments in individuals with DS are associated with a range of cognitive and behavioural outcomes across the lifespan. The strongest associations were observed between hearing impairments and language delays in infancy and childhood, and between visual impairments and adaptive behaviour challenges in childhood and adulthood. Sensory impairments were associated with challenges in similar domains—particularly language, adaptive functioning and learning—across the lifespan. This suggests a potential continuity of these associations over time and that long-standing uncorrected impairments may be associated with reduced cognitive reserve and increased vulnerability to decline—highlighting the need for early identification and intervention.

Background
Self-determination has seen increasing interest in literature worldwide, in terms of its contextualisation, operationalisation and assessment. Developing sound and robust instruments will enable valid assessment both within individual countries and in cross-cultural comparisons.
Methods
The new Self-Determination Inventory (SDI) was translated and adapted into Portuguese, for people with intellectual and developmental disabilities (IDD) and our goal was to analyse the SDI Portuguese Translation's factorial structure. The inventory was administered to 408 participants, between 13 and 73 years old (27 ± 13.6), 246 females and 162 males, with (n = 146) and without IDD (n = 262). Factor structure, measurement invariance and latent difference between persons with and without IDD were analysed.
Results
The confirmatory factor analysis supported the SDI Portuguese Translations' psychometric properties. The data fit a unidimensional model, indicating that the 21 items represent the construct better than a three-factor model. The measurement invariance across groups confirms that the latent construct can be measured and the assessment used with both groups. However, participants with IDD experience greater variability in scores and tend to report lower levels of self-determination.
Conclusions
Findings provide support for the use of SDI Portuguese Translation for persons with and without IDD. Implications for research and practice are discussed.
