Bone quality in older adults with intellectual disabilities

Bone Mineral Density Screening in People With Epilepsy and Intellectual Disability

Vitamin D measurements and dual energy x-ray absorptiometry (DXA) scans are recommended in people with intellectual disability and/or epilepsy in order to prevent bone-linked harm. The prevalence of vitamin D supplementation and bone mineral density screening were evaluated in 68 people with epilepsy and intellectual disability (EID) and 68 matched controls with epilepsy without intellectual disability. DXA scans were not performed in any of the people with EID but were performed in 11.8% of the people in the control group. People with EID had a higher vitamin D supplementation rate and were treated with more antiepileptic drugs (AEDs) and more AED combinations, including first generation AEDs. Increased awareness of bone health screening in people with epilepsy and especially EID is warranted.

Low Muscle Strength, Low Bone Mineral Density, and High Body Mass Index Among Adult Special Olympics Athletes: A Cross-Sectional Examination

Adults with intellectual disabilities have increasing life expectancy but may be susceptible to early aging-related conditions. The purpose of this study was to examine associations between the presence of low muscle strength, low bone mineral density, and high body mass index with age and sex in adult Special Olympics athletes. Grip strength (n = 6,477; 40.9% female), chair stand time (n = 6,444; 40.5% female), body mass index (n = 7,824; 43.7% female), and bone mineral density (n = 3,091; 43.2% female) measurements were provided by Special Olympics International. Poor grip strength, chair stand time, bone mineral density, and body mass index were identified in 43.8%, 46.2%, 28.7%, and 50.3% of each sample, respectively. Increasing age was a risk factor for all conditions (odds ratio = 1.30-10.89; p < .05). High rates of adverse health conditions were observed in a sample of adults with intellectual disabilities. Increased risk was observed as early as the fourth decade of life.

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. Longitudinal data about the health of this vulnerable and relatively unhealthy group are needed so that policy and care can be prioritised and for guiding clinical decision making about screening, prevention and treatment to improve healthy ageing.

METHODS AND ANALYSIS

This article presents a summary of the previous findings of the HA-ID study and describes the design of the 10-year follow-up in which a wide range of health data will be collected within five research themes: (1) cardiovascular disease; (2) physical activity, fitness and musculoskeletal disorders; (3) psychological problems and psychiatric disorders; (4) nutrition and nutritional state; and (5) frailty.

ETHICS AND DISSEMINATION

Ethical approval for the 10-year follow-up measurements of the HA-ID study has been obtained from the Medical Ethics Review Committee of the Erasmus MC, University Medical Centre Rotterdam (MEC-2019-0562).

TRIAL REGISTRATION NUMBER

This cohort study is registered in the Dutch Trial Register (NTR number NL8564) and has been conducted according to the principles of the Declaration of Helsinki.

Nutritional and bone health status in young men with mild-to-moderate intellectual disability and without intellectual disability residing in community setting in Malaysia

BACKGROUND

This study aimed to compare the nutritional and bone health status between young men with mild-to-moderate intellectual disability and those without intellectual disability and to determine predictors for their bone health status.

METHOD

A total of 95 men (47 men with intellectual disability; 48 men without intellectual disability), aged 20-39 years, participated in this study. Anthropometric profile, dietary intake, physical activity level and calcaneal speed of sound (SOS) were collected.

RESULTS

The men with intellectual disability had moderate diet quality whilst the men without intellectual disability had poor diet quality. More participants with intellectual disability (97.9%) were inactive compared with their counterparts (10.4%). The SOS value was similar between groups and was lower than the reference. Increasing age and low physical activity level were negative predictors for bone health status.

CONCLUSION

Both young men with and without intellectual disability have suboptimal nutritional and bone health status. Strategies to improve their nutritional and bone health status are warranted.

Observed Dietary Intake in Adults with Intellectual Disability Living in Group Homes

Background: There is limited information on the dietary intakes of people with intellectual disability (ID) living in group homes. Objective: To describe and evaluate dietary intake in people with ID. Method: Dietary intake was assessed in a convenience sample of people with ID living in group homes. Dietary assessment used three-day weighed food records and digital food photography. Intakes were compared to the Nutrient Reference Values (NRVs) and dietary recommendations. Results: A sample of 33 adults, (men (M): n = 14; women (W): n = 19), mean age 51 ± 14 years, was recruited from seven group homes. Mean daily energy intake was low (M: 7.4 MJ; W: 7.0 MJ; p = 0.46), similar to levels recommended for bed rest. Many participants had intakes below the estimated average requirements (EARs) for the nutrients, magnesium (M: 86%; W: 63%), calcium (M: 43%; W: 78%), iodine (M: 43%; W: 47%) and zinc (M: 43%). Less than half of the recommended daily servings were consumed for vegetables (men and women) and dairy foods (women). Conclusion: Nutrient intake and diet quality of the participants in the group homes studied was poor. Education and policy to support healthier diets is required to improve dietary intake of people with intellectual disability, living in group homes.

Quantitative examination of the bone health status of older adults with intellectual and developmental disability in Ireland: a cross-sectional nationwide study

OBJECTIVES

(1) To investigate the prevalence of osteopenia and osteoporosis among adults with intellectual disabilities (IDs) and (2) to examine alternative optimal bone screening techniques.

DESIGN

Observational cross-sectional study.

SETTING

Wave 2 (2013-2106) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing.

PARTICIPANTS

A national representative sample of 604 male and female persons with ID aged 43 years and over. In total, 575 participants completed quantitative ultrasound (QUS) measurements for one or both feet.

OUTCOME MEASURES

Participants underwent health assessments consisting of eight objective health measures including the standardised QUS of the calcaneus bone using a GE Lunar Achilles. A preinterview questionnaire and face-to-face interview were also completed.

RESULTS

Objectively QUS identified poorer rates of bone health in people with ID overall with 74% indicating evidence of osteopenia (33.2%) or osteoporosis (41%). Females scored lower than males in the QUS t-scores -2.208 (±1.77) versus -1.78(±1.734). Bone status was stratified by gender (p=0.114), age (p=0.003), level of ID (p<0.0001) and living circumstance (p<0.0001).

CONCLUSIONS

This study has shown the prevalence of poor bone health in people with ID is substantial implying an increased risk of fracture due to reduced skeletal integrity. QUS screening has been shown to be useful when combined with clinical risk factors.

General nutrition knowledge among carers at group homes for people with intellectual disability

BACKGROUND

Good nutrition knowledge among carers of people with intellectual disability (ID) living in group homes is essential as they have a primary role in food provision for residents. Research on the nutrition knowledge of carers is limited.

METHOD

This cross-sectional study assessed the level of general nutrition knowledge in a convenience sample of Australian carers (C) of people with ID and compared this to the general Australian community (CM). Nutrition knowledge was evaluated using the validated General Nutrition Knowledge Questionnaire. Total knowledge score as well as performance on instrument sub-sections (dietary guidelines, nutrient sources, healthy food choices and diet disease relationships) were assessed (expressed as %). Knowledge scores were adjusted for known confounders (age, sex, education level, BMI, living arrangement and English spoken at home) using generalised linear modelling.

RESULTS

A total of 589 participants were recruited (C: n = 40; CM: n = 549). Age (C: 40.8 ± 12.1 year; CM: 37.8 ± 13.3 years; P = 0.145), sex distribution (C: 62.5%; CM: 67.2% female; P = 0.602) and English spoken at home (C: 82.5%; CM: 89.6%; P = 0.183) were similar between groups, but BMI (C: 28.5 ± 5.7 kgm^-2 ; CM: 25.3 kgm^-2 ; P = 0.002) was significantly lower and tertiary education (C: 52.5%; CM: 85.1%; P < 0.0005) significantly higher for CM. Total knowledge score (C: 56.6 ± 12.6%; CM: 67.2 ± 12.6%; P < 0.0005) and performance on all instrument sub-sections (P ≤ 0.004) were significantly lower for carers. This remained after confounder adjustment except for the knowledge of dietary guidelines sub-section (P = 0.116).

CONCLUSION

Limited carer nutrition knowledge may compromise their ability to plan and adapt meals to support a healthy and appropriate diet for people with ID in group homes.

An evaluation of the effectiveness of annual health checks and quality of health care for adults with intellectual disability: an observational study using a primary care database

Background

People with intellectual disability (ID) have poorer health than the general population; however, there is a lack of comprehensive national data describing their health-care needs and utilisation. Annual health checks for adults with ID have been incentivised through primary care since 2009, but only half of those eligible for such a health check receive one. It is unclear what impact health checks have had on important health outcomes, such as emergency hospitalisation.

Objectives

To evaluate whether or not annual health checks for adults with ID have reduced emergency hospitalisation, and to describe health, health care and mortality for adults with ID.

Design

A retrospective matched cohort study using primary care data linked to national hospital admissions and mortality data sets.

Setting

A total of 451 English general practices contributing data to Clinical Practice Research Datalink (CPRD).

Participants

A total of 21,859 adults with ID compared with 152,846 age-, gender- and practice-matched controls without ID registered during 2009–13.

Interventions

None.

Main outcome measures

Emergency hospital admissions. Other outcomes – preventable admissions for ambulatory care sensitive conditions, and mortality.

Data sources

CPRD, Hospital Episodes Statistics and Office for National Statistics.

Results

Compared with the general population, adults with ID had higher levels of recorded comorbidity and were more likely to consult in primary care. However, they were less likely to have long doctor consultations, and had lower continuity of care. They had higher mortality rates [hazard ratio (HR) 3.6, 95% confidence interval (CI) 3.3 to 3.9], with 37.0% of deaths classified as being amenable to health-care intervention (HR 5.9, 95% CI 5.1 to 6.8). They were more likely to have emergency hospital admissions [incidence rate ratio (IRR) 2.82, 95% CI 2.66 to 2.98], with 33.7% deemed preventable compared with 17.3% in controls (IRR 5.62, 95% CI 5.14 to 6.13). Health checks for adults with ID had no effect on overall emergency admissions compared with controls (IRR 0.96, 95% CI 0.87 to 1.07), although there was a relative reduction in emergency admissions for ambulatory care-sensitive conditions (IRR 0.82, 95% CI 0.69 to 0.99). Practices with high health check participation also showed a relative fall in preventable emergency admissions for their patients with ID, compared with practices with minimal participation (IRR 0.73, 95% CI 0.57 to 0.95). There were large variations in the health check-related content that was recorded on electronic records.

Limitations

Patients with milder ID not known to health services were not identified. We could not comment on the quality of health checks.

Conclusions

Compared with the general population, adults with ID have more chronic diseases and greater primary and secondary care utilisation. With more than one-third of deaths potentially amenable to health-care interventions, improvements in access to, and quality of, health care are required. In primary care, better continuity of care and longer appointment times are important examples that we identified. Although annual health checks can also improve access, not every eligible adult with ID receives one, and health check content varies by practice. Health checks had no impact on overall emergency admissions, but they appeared influential in reducing preventable emergency admissions.

Future work

No formal cost-effectiveness analysis of annual health checks was performed, but this could be attempted in relation to our estimates of a reduction in preventable emergency admissions.

An exploration of the bone health of older adults with an intellectual disability in Ireland

BACKGROUND

Many risk factors have been confirmed for poor bone health among the general population including age, gender and corticosteroid use. There is a paucity of investigation among people with intellectual disability; however, research points to differing risks namely anti-epileptic medication use, Down syndrome and poor behaviour lifestyle.

METHODS

Data was extracted from the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing in Ireland. In total, 753 participants took part, and data was gathered on participants' health status, behavioural health, health screenings and activities of daily living. The prevalence of osteoporosis and related risk factors were specifically examined.

RESULTS

Overall, 8.1% reported a doctor's diagnosis of osteoporosis with over 20% reporting history of fracture. Risk identified included older age (P < 0.0001), female gender (P < 0.0001), difficulty walking (P < 0.0001) with older age and being female the stronger predictors for osteoporosis, odds ratio = 6.53; 95% confidence interval 2.82-15.11 and odds ratio = 4.58; 95% confidence interval 2.29-9.17, respectively. There was no gender difference regarding the level of fractures; however, epilepsy and anti-epileptic medication were strong predictors. Overall, 11.1% attended for bone screening diagnostics.

CONCLUSION

Despite low levels of reported doctor's diagnosis of osteoporosis risk factor prevalence was high. Considering the insidious nature of osteoporosis and the low levels of diagnostic screening, prevalence could be possibly higher.

Prevalence of reported physical health problems in people with severe or profound intellectual and motor disabilities: a cross-sectional study of medical records and care plans

BACKGROUND

People with severe or profound intellectual and motor disabilities (SPIMD) experience numerous serious physical health problems and comorbidities. Knowledge regarding the prevalence of these problems is needed in order to detect and treat them at an early stage. Data concerning these problems in individuals with SPIMD are limited. Therefore, the aim of this study was to determine the prevalence of reported physical health problems in adults with SPIMD through a review of medical records and care plans.

METHOD

We conducted a cross-sectional study employing data obtained from medical and support records. A sample of adults with SPIMD was recruited in eight residential care settings. Physical health problems that had occurred during the previous 12 months or were chronic were recorded.

RESULTS

The records of 99 participants were included. A wide range of physical health problems were found with a mean of 12 problems per person. Very high prevalence rates (>50%) were found for constipation, visual impairment, epilepsy, spasticity, deformations, incontinence and reflux.

CONCLUSIONS

The results suggest that people with SPIMD simultaneously experience numerous, serious physical health problems. The reliance on reported problems may cause an underestimation of the prevalence of health problems with less visible signs and symptoms such as osteoporosis and thyroid dysfunction.

The use of a frailty index to predict adverse health outcomes (falls, fractures, hospitalization, medication use, comorbid conditions) in people with intellectual disabilities

Frailty in older people can be seen as the increased likelihood of future negative health outcomes. Lifelong disabilities in people with intellectual disabilities (ID) may not only influence their frailty status but also the consequences. Here, we report the relation between frailty and adverse health outcomes in older people with ID (50 years and over). In a prospective population based study, frailty was measured at baseline with a frailty index in 982 older adults with ID (≥50 yr). Information on negative health outcomes (falls, fractures, hospitalization, increased medication use, and comorbid conditions) was collected at baseline and after a three-year follow-up period. Odds ratios or regression coefficients for negative health outcomes were estimated with the frailty index, adjusted for gender, age, level of ID, Down syndrome and baseline adverse health condition. The frailty index was related to an increased risk of higher medication use and several comorbid conditions, but not to falls, fractures and hospitalization. Frailty at baseline was related to negative health outcomes three years later in older people with ID, but to a lesser extent than found in the general population.

Risk for osteopenia and osteoporosis in institution-dwelling individuals with intellectual and/or developmental disabilities

The purpose of this study was to investigate the prevalence of and contributing factors to osteopenia and osteoporosis among people with intellectual disabilities (ID) or/and developmental disabilities (DD) residing in a disability institution in Taiwan. The present study was conducted at one disability institution in Taiwan and recruited 184 institutionalized residents with ID and/or DD (115 men and 69 women aged 18-72 years) for analysis. For all residents with ID and/or DD, information was obtained about their age, gender, level of ID, BMI, and bone mineral density (BMD). BMD is a measurement of calcium levels in bones that can estimate the risk of osteoporosis and bone fractures. Bone tests were divided into three outcome categories based on their calcaneal BMD T-scores: Normal BMD, a T-score≧-1; Osteopenia, -2.5≦T-score<-1; and Osteoporosis, a T-score<-2.5. The results revealed that 46.2% of cases were normal and that 27.7% and 26.1% of cases had osteopenia and osteoporosis, respectively. Multiple logistic regression analyses found that male gender (OR=2.482, 95% CI=1.04-5.93, p<0.05), age≧40 years (OR=3.051, 95% CI=1.07-8.69, p<0.05) and being overweight/obese (OR=0.395, 95% CI=0.17-0.93, p<0.05) were more likely to be associated with osteoporosis. Another model indicated that males (OR=2.169, 95% CI=1.12-4.19, p<0.05) and those aged≧40 years (OR=3.026, 95% CI=1.32-7, p<0.01) tended to have an increased risk for osteopenia and osteoporosis. To improve the bone quality of individuals with ID or/and DD and to decrease the occurrence of osteopenia and osteoporosis, this study highlights that we should pay much attention to the potential risk factors for bone quality in these vulnerable populations.
