Cardiovascular risk and treatment for adults with intellectual or developmental disabilities

Training responsiveness of cardiorespiratory fitness and arterial stiffness following moderate-intensity continuous training and high-intensity interval training in adults with intellectual and developmental disabilities

BACKGROUND

Cardiorespiratory fitness (CRF) prompts antiatherogenic adaptations in vascular function and structure. However, there is an extraordinary interindividual variability in response to a standard dose of exercise, wherein a substantial number of adults with intellectual and developmental disabilities (IDD) do not improve CRF. We (1) evaluated the effects of 12-month of moderate-intensity continuous training (MICT) on CRF and arterial stiffness and (2) tested whether an additional 3-month of high-intensity interval training (HIIT) would add to improvements in CRF responsiveness and arterial stiffness.

METHODS

Fifteen adults with mild-to-moderate IDD (male adults = 9, 30.1 ± 7.5 years old) met 3 days per week for 30 min MICT for 12 months, after which the incidence of CRF responsiveness was calculated (≥5.0% change in absolute peak VO₂ ). Thereafter, responders and non-responders started HIIT for 3 months with identical daily training load/frequency. Peak VO₂ , local and regional indices of arterial stiffness were assessed prior to and after each period.

RESULTS

Sixty per cent of the participants were non-responders following MICT, but the incidence dropped to 20% following HIIT (P = 0.03). Absolute peak VO₂ values reached significant difference from pre-intervention (+0.38 ± 0.08 L min^-1 , P = 0.001) only when HIIT was added. Lower limb pulse wave velocity (PWV) decreased following MICT (-0.8 ± 1.1 m s^-1 , P = 0.049), whereas central PWV only decreased following HIIT (-0.8 ± 0.9 m s^-1 , P = 0.013).

CONCLUSIONS

Cardiorespiratory fitness responsiveness and reductions in PWV to a 12-month MICT period in adults with IDD improved following a period of HIIT programme inducing higher metabolic stress.

Exploring chronic disease prevalence in people with intellectual disabilities in primary care settings: A scoping review

BACKGROUND

Primary care providers require accurate evidence on chronic disease prevalence in people with intellectual disabilities in order to apply this information into practice. This study aimed to map the broadness of literature on chronic disease prevalence in people with and without intellectual disabilities, and to explore main characteristics of these studies.

METHOD

A scoping review of peer-reviewed literature was conducted, covering 2000 to February 2020, including literature that discussed chronic disease prevalence in people with and without intellectual disabilities, with similar data collection method for both groups.

RESULTS

Nineteen studies were included. Chronic disease prevalence varied considerably between people with and without intellectual disabilities. Studies differed in their methodologies, country and age groups that were enrolled.

CONCLUSIONS

Primary care providers should interpret results on disease prevalence among people with intellectual disabilities in light of the study characteristics. Researchers should always interpret prevalence rates in the context of methodology.

Caregiver resource utilization: Intellectual and development disability and dementia

BACKGROUND

Adults with intellectual and developmental disabilities and their families have high need for support services. This study assessed resource utilization among caregivers of intellectual and developmental disabilities and other conditions.

METHODS

We assessed 366 caregivers of adults with intellectual and developmental disabilities, dementia or other conditions Regressions assessed group differences in number of agency contacts and frequency of service use. A secondary analysis assessed reasons for underutilization of services.

RESULTS

Caregivers of individuals with dementia contacted twice as many agencies as other caregivers and were more likely to report using suggested services. Agency contact and service utilization were similar among caregivers of adults with intellectual and developmental disabilities compared to other caregivers. Caregivers of adults with intellectual and developmental indicated that suggested services were unavailable to them.

CONCLUSION

The findings of this study shed light on challenges with access to and utilization of support services.

The prevalence, awareness, treatment, and control of hypertension in older adults with an intellectual disability in Ireland: a cross sectional study

Aims

Hypertension is a leading risk factor for cardiovascular disease, accounting for almost 50% of ischaemic heart disease mortality. This study aims to identify the prevalence, awareness, treatment, and control of hypertension and their predictors in older adults with an intellectual disability (ID).

Methods and results

This cross-sectional study utilized data from the ID Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA). Participants were drawn from the nationally representative sample and included those who completed the self/informant report measures, in addition to objective blood pressure (BP) measurement. From the 551 individuals with ID, aged ≥40 years, hypertension prevalence was 35.2% [95% confidence interval (CI) 31.2–39.2%]. Of those with hypertension, 44.3% (95% CI 37.1–51.5%) were aware of their hypertensive status, and 64.2% (95% CI 57.3–71.1) were taking antihypertensive medication. Among those on treatment, 70.8% (95% CI 61.8–78.2%) had their BP controlled to below 140/90 mmHg. Significant predictors of awareness were age (P = 0.036) and level of ID (P = 0.004), predictors of treatment were age (P = 0.002), level of ID (P = 0.019), and diabetes (P = 0.001). Both diabetes and female gender were predictors of control of hypertension (P = 0.013 and P = 0.037, respectively).

Conclusion

The prevalence of hypertension in older adults with ID was lower than reports for the general Irish population, with overall levels of treatment and control, when identified, higher in the ID population. There was under-treatment and lower levels of awareness among those with more severe ID, which requires addressing. The finding, that when diagnosed, people with ID respond well to treatment should encourage addressing the under-treatment found here.

Testing a Wellness Indicators Measure for People with Intellectual and Developmental Disabilitiesa

BACKGROUND AND PURPOSE

People with intellectual and developmental disabilities (IDD) often have health and wellness issues that are not as good as people without disabilities. States are required to monitor health and wellness for people with IDD who use many disability services. However, there are few ways to monitor wellness between states or at different points in time. In this study, we share a new model that states may use to monitor wellness of people with IDD.

METHODS

We used data from a survey called the National Core Indicators (NCI) to develop this model. First, we developed the model using our state's data. Then, after we found a model that worked well, we tested that model using the National Core Indicators from the entire U.S.

RESULTS

Our final model worked well in both our state NCI data and the national NCI data. This is important because policies at both levels can affect the services that people with disabilities can use. Our model had three parts: heart health, mental health, and behavioral wellness. These are described more in the paper. We also used statistics to test some factors that might predict outcomes related to heart health, mental health, and behavioral wellness. Age, sex, where someone lives, and level of intellectual disability were all good predictors of all three categories of wellness that we studied.

IMPLICATIONS

The model of wellness that we developed worked well but should be tested using data from other individual states. It is very important to know about health and wellness right now since the services people with disabilities can use are changing in many states. We think our model can help planners and advocates understand how services affect wellness in a way that is easy to compare from state to state and at different points in time.

Chronic Health Conditions in Aging Individuals with Intellectual Disabilities

Life expectancy of people with intellectual disability (ID) has increased in recent decades. However, there is little evidence of whether these extra years of life are spent in good health. The aim of this study, conducted in Spain, is to obtain information about the prevalence of chronic health conditions in people with ID over the age of 44 and compare it with that of their peers without disability. Twenty health conditions were analyzed in 1040 people with ID and 12,172 people without ID through a study of their prevalence. The findings show that chronic constipation, urinary incontinence, thyroid disorders and obesity are the most prevalent chronic diseases among individuals with ID. In addition, this population group suffers these health conditions more frequently than older adults without ID. Detection and early intervention in these health conditions will improve adequate access to social health services and subsequent treatment of aging adults with ID.

Disparities in the Use of Guideline-Based Pharmacotherapy Exist for Atherosclerotic Cardiovascular Disease and Heart Failure Patients Who Have Intellectual/Developmental Disabilities in a Commercially Insured Database

BACKGROUND

Patients who have intellectual/developmental disabilities (IDDs) develop atherosclerotic cardiovascular disease (ASCVD) or heart failure (HF) at rates similar to or higher than the general population. They also face disparities accessing and using health care services.

OBJECTIVE

To determine if disparities exist in the use of guideline-based pharmacotherapy (GBP) for ASCVD or HF for adults with IDD.

METHODS

Using the 2014 Clinformatics Data Mart Database, adults with ASCVD or HF were divided into IDD or non-IDD groups. Patients with contraindications for GBP medications were excluded. Use of GBP between IDD and non-IDD groups was examined. Subgroup analysis included comparisons between IDD groups.

RESULTS

For HF, 1011 patients with IDD and 236,638 non-IDD patients were identified. For ASCVD, 2190 IDD and 790,343 non-IDD patients were identified. We found that 47.9%, 35.8%, and 13.1% of IDD and 58.7%, 48.4%, and 18.9% of non-IDD patients had pharmacy claims for statins (P < 0.001), β-blockers (P < 0.001), or antiplatelet therapy (P < 0.001), respectively. For HF, 46.8% and 50.3% of IDD and 59.8% and 55.4% of non-IDD patients had pharmacy claims for β-blockers (P < 0.001) and angiotensin-converting enzyme (ACE) inhibitors or angiotensin-receptor blockers (ARBs; P = 0.003), respectively. In all but one multivariate regression models patients with IDD were less likely to use GBP than patients in the non-IDD group. Subgroup analysis revealed that patients who had Down syndrome had lower GBP use in 4 of the 5 measures.

CONCLUSION AND RELEVANCE

Disparities exist in the use of GBP for patients with IDD with ASCVD or HF. Patients who have an IDD should be examined by clinicians to ensure appropriate access to and use of GBP.

The risk, burden, and management of non-communicable diseases in cerebral palsy: a scoping review

AIM

To examine the risk, burden, and management of non-communicable diseases (NCDs) among people with cerebral palsy (CP).

METHOD

Databases (Ovid MEDLINE, Embase Ovid, CINAHL Plus) were systematically searched up to August 2017. Data on the prevalence of risk factors for, and the burden and management of, cardiovascular diseases, diabetes, cancers, and respiratory diseases were extracted.

RESULTS

Thirty-six studies that examined the prevalence of risk factors among people with CP were identified. There was inconsistent evidence that people with CP had higher prevalence of metabolic risk factors such as hypertension, hyperlipidaemia, and obesity, but strong evidence that they participated in low levels of physical activity, compared with people without CP. Seven studies reported on the burden of NCDs. Adults with CP had a higher risk of NCDs, including stroke, chronic obstructive pulmonary disease, and other heart conditions, and death due to NCDs, including cancers, chronic obstructive pulmonary disease, stroke, and ischaemic heart disease, compared with the general population. Only one study reported on the management of NCD, specifically the uptake of breast cancer screening among females.

INTERPRETATION

The burden of NCDs is higher among adults with CP compared with the general population. Further research is required to determine the prevalence of metabolic risk factors and management of NCDs among people with CP.

WHAT THIS PAPER ADDS

Adults with cerebral palsy (CP) have an increased risk of non-communicable diseases (NCDs) and increased risk of death because of NCDs. Evidence is inconsistent about the elevated prevalence of metabolic risk factors for NCDs. Evidence is consistent that people with CP participate in reduced physical activity. Only one study reported on management of NCD among people with CP. Available evidence suggests people with CP are less likely to receive preventive medicine.

Stress Measured by Allostatic Load in Neurologically Impaired Children: The Importance of Nutritional Status

BACKGROUND

Allostatic load (AL) is the cumulative physiological wear and tear that results from repeated efforts to adapt to stressors over time. The life stress response is modified by nutritional status.

AIM

We estimated AL scores among neurologically impaired (NI) children; the association with malnutrition was also evaluated.

METHODS

Forty-one patients with severe disabilities were included. Data based on 15 biomarkers were used to create the AL score. A dichotomous outcome of high AL was defined for those who had ≥6 dysregulated components. Body mass index (BMI)-standard deviation score (SDS) <-2 or SDS ≥2 and biochemical markers (≥4) defined malnutrition.

RESULTS

High AL was noted in 17/41 of the whole sample (41.47%). Malnutrition occurred in 36.6% of the subjects. A significant correlation between high AL and malnutrition was observed (p = 0.01; ar ea under the receiver operating characteristic curve, 0.7457). High AL subjects had a significantly higher BMI (p = 0.009) and lower BMI-SDS (p = 0.003) than low AL subjects. AL score correlated with fat mass (p ≤ 0.01) and negatively correlated with fat-free mass (p ≤ 0.02).

CONCLUSION

In NI children, high AL was associated with malnutrition. Body composition is a better indicator than BMI of allostatic adjustments. AL estimation should be considered a measure of health risk and be used to promote quality of life in at-risk disabled populations.

Epicardial Fat Thickness in Non-Obese Neurologically Impaired Children: Association with Unfavorable Cardiometabolic Risk Profile

Background: Cardiovascular risk is reported in disabled children and epicardial fat (EF) is considered an independent predictor of cardiovascular disease (CVD). No data on the EF thickness (EFT) evaluation in disabled children have been published. Objective: We investigated EFT in neurologically impaired (NI) children; its relationship with their metabolic profile was also considered. Methods: Clinical data, body composition estimation, biochemical profile, and ultrasound-measured EFT were performed in 32 disabled patients (12.4 ± 6.3 years). Pathological parameters were defined using the following criteria: waist circumference >95th percentile, waist to height ratio (WHtR) >0.5, total cholesterol and triglycerides (TG) values >95th percentile, high density lipoprotein cholesterol <5th percentile, fasting blood glucose >100 mg/dL, homeostasis model assessment for insulin resistance (HOMA) >97.5th percentile, and EFT >3.6 mm. Results: EFT values in NI children were higher compared with control group values (p = 0.02). EFT correlated with gender (p < 0.001), age (p = 0.02), pubertal stage (p = 0.04), as well as WHtR (p = 0.03). A correlation between EFT and leptin was also noted (p = 0.04). EFT levels significantly correlated with pathological TG (p = 0.01) and HOMA-IR (p = 0.04). Conclusions: Higher EFT was observed in NI children compared with controls. EFT values correlated with clinical, metabolic, and endocrinological parameters. Ultrasound-measured EFT could be used to promptly detect subclinical CVD and to prevent adverse outcomes in disabled children.

Changes in Energy Intake and Diet Quality during an 18-Month Weight-Management Randomized Controlled Trial in Adults with Intellectual and Developmental Disabilities

BACKGROUND

Previous research indicates that individuals with intellectual and developmental disabilities (IDDs) are at risk for poor diet quality.

OBJECTIVE

The purpose of this secondary analysis was to determine whether two different weight-loss diets affect energy intake, macronutrient intake, and diet quality as measured by the Healthy Eating Index-2010 (HEI-2010) during a 6-month weight-loss period and 12-month weight-management period, and to examine differences in energy intake, macronutrient intake, and HEI-2010 between groups.

DESIGN

Overweight/obese adults with IDDs took part in an 18-month randomized controlled trial and were assigned to either an enhanced Stop Light Diet utilizing portion-controlled meals or a conventional diet consisting of reducing energy intake and following the 2010 Dietary Guidelines for Americans. Proxy-assisted 3-day food records were collected at baseline, 6 months, and 18 months, and were analyzed using Nutrition Data System for Research software. HEI-2010 was calculated using the data from Nutrition Data System for Research.

PARTICIPANTS/SETTING

The study took place from June 2011 through May 2014 in the greater Kansas City metropolitan area.

MAIN OUTCOME MEASURES

This was a secondary analysis of a weight-management intervention for adults with IDDs randomized to an enhanced Stop Light Diet or conventional diet, to examine differences in energy intake, macronutrient intake, and HEI-2010 across time and between groups.

STATISTICAL ANALYSES PERFORMED

Independent- and paired-samples t tests and general mixed modeling for repeated measures were performed to examine group differences and changes at baseline, 6 months, and 18 months between the enhanced Stop Light Diet and conventional diet groups.

RESULTS

One hundred and forty six participants (57% female, mean±standard deviation age=36.2±12.0 years) were randomized to either the enhanced Stop Light Diet or conventional diet group (77 enhanced Stop Light Diet, 69 conventional diet) and provided data for analysis at baseline, 124 completed the 6-month weight-loss period, and 101 completed the 18-month study. Participants on the enhanced Stop Light Diet diet significantly reduced energy intake at 6 and 18 months (both P<0.001), but those on the conventional diet did not (both P=0.13). However, when accounting for age, sex, race, education level, and support level (mild vs moderate IDD), there was a significant decrease during the 18-month intervention in energy intake for the enhanced Stop Light Diet and conventional diet groups combined (P<0.01 for time effect), but no significant group difference in this change (P=0.39 for group-by-time interaction). There was no significant change in total HEI-2010 score at 6 and 18 months (P=0.05 and P=0.38 for the enhanced Stop Light Diet group; P=0.22 and P=0.17 for the conventional diet group), and no significant group difference at 6 and 18 months (P=0.08 and P=0.42). However, when participants' age, sex, race, education level, and support level were accounted for, mixed modeling indicated a significant increase in total HEI-2010 scores for the enhanced Stop Light Diet and conventional diet groups combined during the 18-month intervention (P=0.01 for time effect).

CONCLUSIONS

The results of this study found that after controlling for demographic factors, individuals with IDDs can decrease their energy intake and increase their diet quality, with no significant differences between the enhanced Stop Light Diet and conventional diet groups.
