Measurement protocols and determinants of peak oxygen consumption in adults with Down syndrome: a systematic review.

This systematic review aimed to provide an overview of test protocols used to measure peak oxygen uptake (VOpeak) in adults with Down syndrome (DS) and to determine how generalisable the outcomes are for the entire population of adults with DS by describing the sample characteristics of these studies and their impact on VOpeak. A literature search (PROSPERO CRD42022309560) was performed (18 July 2023) using the following databases: PubMed, CINAHL, APA PsycINFO, Web of Science, Embase and SPORTDiscus. For articles to be included, they had to be peer-reviewed pubications, reporting VOpeak or VOmax for individuals with DS separately, with a sample of n ≥ 5 and a mean age ≥18 years.

Effects of a 12-week telehealth exercise intervention on gait speed and gait deviations in adults with Down syndrome.

Background: Altered gait patterns and reduced walking speed are commonly reported in adults with Down syndrome (DS). Research on the effects of DS-specific exercise programmes on adults with DS is lacking. The purpose of this quasi-experimental study was to evaluate the changes in gait deviations and walking speed in adults with DS after a DS-specific exercise programme.

A questionnaire to measure direct support professionals' attitude towards healthy nutrition of people with intellectual disabilities.

Background: Direct support professionals' (DSPs') attitudes toward nutrition are important for supporting a healthy lifestyle of persons with intellectual disabilities. However, there are no instruments to measure it. The aim of this study was to compose a questionnaire and determine its internal validity.

Associations between physical fitness and cardiovascular disease in older adults with intellectual disabilities: Results of the Healthy Ageing and Intellectual Disability study.

Background: Reduced physical fitness is a cardiovascular disease (CVD) risk factor in the general population. However, generalising these results to older adults with intellectual disabilities (ID) may be inappropriate given their pre-existing low physical fitness levels and high prevalence of co-morbidities. Therefore, the aim of this study is to investigate the difference in physical fitness between older adults with ID with and without CVD.

Development of a Physical Therapy-Based Exercise Program for Adults with Down Syndrome.

In adults with Down syndrome, the combination of low physical activity and fitness levels and the high prevalence of musculoskeletal co-morbidities stresses the need for specialized exercise programs. The goal of this research study was to develop a specialized exercise program for individuals with Down syndrome using the physical therapy approach of a systems review as the foundation. We first conducted an overview of the literature on co-morbidities in adults with Down syndrome using the systems review method to categorize these findings.

The effect of a telehealth exercise intervention on balance in adults with Down syndrome.

Background: People with Down syndrome often present with balance deficits, which compromise safety during daily activity. While evidence shows that exercise can improve balance in the Down syndrome population, it is unclear if a telehealth method will elicit similar benefits. We aimed to examine the effects of a virtual exercise program on balance in adults with Down syndrome.

Cardiac Structure and Function in Adults with Down Syndrome.

Various factors may alter the risk for cardiovascular disease in adults with Down syndrome (Ds), yet few studies have examined differences in cardiac physiology in this population. Previous research suggested lower systolic and diastolic function, but inconsistent methodologies and younger samples warrant research in adults with Ds. Our aim is to compare the cardiac structure and function of adults with Ds to age- and sex-matched adults without Ds.

Comprehensive cardiopulmonary profile of individuals with Down syndrome.

Background: Individuals with Down syndrome (DS) have low levels of cardiorespiratory fitness and previous studies have shown that these low levels of fitness have a physiological cause. During exercise, the cardiovascular, ventilatory and muscular systems are simultaneously active. While individual parameters of these systems have been investigated in DS before, the interaction between these parameters and systems have not been discussed in detail.

Behaviour change techniques used in lifestyle support of adults with mild intellectual disabilities.

Background: Professional caregivers are important in the daily support of lifestyle change for adults with mild intellectual disabilities; however, little is known about which behaviour change techniques (BCTs) are actually used. This study aims to gain insight in their use for lifestyle behaviour change using video observations.

Methods: Professional caregivers (N = 14) were observed in daily work supporting adults with mild intellectual disabilities.

The responsiveness of muscle strength tests in adults with intellectual disabilities.

Background: Muscle strength is both a strong predictor for future negative health outcomes and a prerequisite for physical fitness and daily functioning of adults with ID. Therefore, it is important to be able to monitor the muscle strength of adults with ID over time. The aim of this study is to assess the responsiveness of five field tests that measure muscle strength and endurance (grip strength, hand-held dynamometry of leg extension and arm flexion, 10RM-test of the seated squat and the biceps curl, 30-s chair stand and the 5-times Chair stand) in adults with ID after a 24-week resistance-exercise training (RT) programme.

Development of a Dutch Training/Education Program for a Healthy Lifestyle of People With Intellectual Disability.

Individuals with intellectual disability (ID) need support from direct support professionals (DSPs) to engage in a healthy lifestyle. However, literature shows DSPs feel insufficiently equipped to support a healthy lifestyle. Therefore, the aim of this study is to develop a theory-based program for DSPs to support physical activity and healthy nutrition for people with moderate to profound levels of ID, and to design its evaluation.

Healthy Ageing and Intellectual Disability study: summary of findings and the protocol for the 10-year follow-up study.

Introduction: The Healthy Ageing and Intellectual Disability (HA-ID) study is a prospective multicentre cohort study in the Netherlands that started in 2008, including 1050 older adults (aged ≥50) with intellectual disabilities (ID). The study is designed to learn more about the health and health risks of this group as they age. Compared with the amount of research in the general population, epidemiological research into the health of older adults with ID is still in its infancy.

Implementation of a program to support direct support professionals to promote a healthy lifestyle for people with moderate to profound intellectual disabilities.

Background: There is a lack of theory-based interventions for direct support professionals (DSPs) to support a healthy lifestyle for people with moderate to profound intellectual disabilities (ID) despite their major role in this. This study aims to evaluate the preparation, implementation, and preliminary outcomes of a theory-based training and education program for DSPs to learn how to support these individuals.

Methods: The program consisting of e-learning, three in-person sessions, and three assignments was implemented.

Development and validation of a shortened and practical frailty index for people with intellectual disabilities.

Background: There is no widely used instrument to detect frailty in people with intellectual disabilities (IDs). We aimed to develop and validate a shorter and more practical version of a published frailty index for people with IDs.

Method: This study was part of the longitudinal 'Healthy Ageing and Intellectual Disability' study.

Gaining actionable knowledge to improve local health-promoting capacities in long-term care support settings for people with intellectual disabilities.

Objective: People with intellectual disabilities (ID) are largely dependent on their environment to live healthily and, in this, ID-support organizations play a vital role. An environmental asset mapping tool for ID-support settings has been developed. This study aims to provide insight into whether or not the tool can provide a comprehensive view on assets in the system and actionable knowledge to improve health-promoting capacities in ID-support settings.

Blunted autonomic response to standing up and head-up tilt in individuals with intellectual disabilities.

Previous research suggests individuals with intellectual disabilities (ID) may experience autonomic dysfunction, however, this has not been thoroughly investigated. The aim of this study was to compare the autonomic response to standing up (active orthostasis) and head-up tilt (passive orthostasis) in individuals with ID to a control group without ID. Eighteen individuals with and 18 individuals without ID were instrumented with an ECG-lead and finger-photoplethysmography for continuous heart rate and blood pressure recordings.

Determining Frailty in People With Intellectual Disabilities in the COVID-19 Pandemic.

Background: Across the world, frailty is part of the guidelines that are being developed in the COVID-19 pandemic for triaging in crisis situations. The Clinical Frailty Scale (CFS) evaluates the ability to perform daily tasks to identify frail individuals, potentially excluding those from intensive care (IC) treatment. Individuals with intellectual disabilities (ID) experience varying degrees of dependence, distinct from age-related physical deterioration.

Anthropometry does not fully explain low fitness among adults with Down syndrome.

Background: Cardiorespiratory fitness, expressed as peak oxygen uptake during exercise (VO peak), is an important predictor of cardiovascular health and is related to anthropometry in the general population. Individuals with Down syndrome (DS) have reduced cardiorespiratory fitness and often exhibit different anthropometrics compared with the general population. Interestingly, the relation between anthropometry and cardiorespiratory fitness found in the general population is not apparent in individuals with DS.

Use of behaviour change techniques by direct support professionals to support healthy lifestyle behaviour for people with moderate to profound intellectual disabilities.

Background: Behaviour change techniques (BCTs) can be employed to support a healthy lifestyle for people with intellectual disabilities. The aim of this study is to determine whether and which BCTs are used by direct support professionals (DSPs) for supporting healthy lifestyle behaviour of people with moderate to profound intellectual disabilities.

Method: Direct support professionals (n = 18) were observed in their daily work using audio-visual recordings.

The association between medication use and gait in adults with intellectual disabilities.

Background: Adults with intellectual disabilities (ID) often have polypharmacy and often use antipsychotics. Both polypharmacy and antipsychotics have a negative effect on gait in the general population, but this has not been studied in adults with ID. These negative effects may add to pre-existing gait disturbances in adults with ID and increase the risk for adverse health outcomes in this population.

Hemodynamic Response to Isometric Handgrip Exercise in Adults with Intellectual Disability.

Introduction: Individuals with intellectual disability (ID) have an increased risk of cardiovascular disease and reduced work capacity, which could partly be explained by alterations to autonomic and hemodynamic regulation. The measurement of heart rate and blood pressure during isometric handgrip (HG) exercise, a sympathoexcitatory stimulus, is a noninvasive method to investigate autonomic and hemodynamic alterations. The purpose of this study was to assess alterations to autonomic and associated hemodynamic regulation between individuals with ID and a matched control group during isometric HG exercise.

How can care settings for people with intellectual disabilities embed health promotion?

Background: People with intellectual disabilities (ID) depend on their environment to live healthily. Asset-based health promotion enhances a settings' health-promoting capacity starting with identifying protective or promotive factors that sustain health.

Method: This inclusive mixed-methods study used group sessions to generate and rank ideas on assets supporting healthy nutrition and physical activity in Dutch intellectual disability care settings.

Is fatness or fitness key for survival in older adults with intellectual disabilities?

Background: Overweight/obesity and poor physical fitness are two prevalent lifestyle-related problems in older adults with intellectual disabilities, which each require a different approach. To improve healthy ageing, we assessed whether fatness or fitness is more important for survival in older adults with intellectual disabilities.

Methods: In the HA-ID study, we measured obesity and fitness of 874 older adults with intellectual disabilities (61.

Hypertension in Adults With Intellectual Disability: Prevalence and Risk Factors.

Introduction: Individuals with intellectual disability have a high prevalence of obesity and low physical activity levels, which are risk factors for hypertension. This study estimated the prevalence of hypertension in a global data set of adults with intellectual disability participating in Special Olympics and investigated the role of physical activity and obesity in hypertension risk.

Methods: A total of 33,122 individuals aged ≥18 years with intellectual disability who participated in Special Olympic events from 2014 to 2018 had their brachial blood pressure, BMI, and self-reported physical activity assessed.
