Patterns in the prevalence of diabetes and incidence of diabetic complications in people with and without an intellectual disability in Dutch primary care: Insights from a population-based data-linkage study

Participation in Special Olympics reduces the rate for developing diabetes in adults with intellectual and developmental disabilities

AIM

Adults with intellectual and developmental disabilities (IDD) have a significantly higher prevalence of Type 2 diabetes than the general population. Evidence that lifestyle and/or behavioural interventions, such as participation in Special Olympics, decreases the risk of developing diabetes in adults with IDD could help minimize health disparities and promote overall health in this population.

METHODS

This was a 20-year retrospective cohort study of adults with IDD (30-39 years) in the province of Ontario, Canada, that compared hazard rates of diabetes among Special Olympics participants (n = 4145) to non-participants (n = 31,009) using administrative health databases housed at ICES. Using cox proportional hazard models, crude and adjusted hazard ratios were calculated for the association between the primary independent variable (Special Olympics participation status) and the dependent variable (incident diabetes cases).

RESULTS

After controlling for other variables, the hazard ratio comparing rates for developing diabetes between Special Olympics participants and non-participants was 0.85. This represents a 15% reduction in the hazard among Special Olympics participants when followed for up to 20 years. This result was statistically significant and represents a small effect size.

CONCLUSIONS

Special Olympics could be considered a complex intervention that promotes physical activity engagement through sport participation, health screenings, and the promotion of healthy eating habits through educational initiatives. This study provides evidence that Special Olympics participation decreases the rate for developing diabetes.

Pattern of multimorbidity in middle-aged and older-aged people with mild intellectual disability in Australia

BACKGROUND

Non-communicable diseases (NCDs), also known as chronic diseases, now constitute a major proportion of ill-health across most adult and older populations including in people with intellectual disability. The current paper is a comparative analysis of prevalence of NCDs across mid-aged and older-aged people with mild intellectual disability.

METHOD

Comparative data comes from two cross-sectional surveys using similar methodology and timeframes. The analysis sample comprises mid-aged group (30-50 years, N = 291) and older-aged group (≥60 years, N = 391).

RESULTS

People with mild intellectual disability start developing NCDs in early to mid-adulthood and increases with age. The mean number of NCDs in mid-aged group was 0.86 (SD, 0.84) compared to 3.82 in older group (SD, 2.67).

CONCLUSION

There needs to be early identification and management of NCDs using relevant health promotion and preventative measures at optimal intervention points. The training of healthcare professionals needs improvement.

A Scoping Review of Wearable Technologies for Use in Individuals With Intellectual Disabilities and Diabetic Peripheral Neuropathy

BACKGROUND

Individuals with intellectual disabilities (IDs) are at risk of diabetes mellitus (DM) and diabetic peripheral neuropathy (DPN), which can lead to foot ulcers and lower-extremity amputations. However, cognitive differences and communication barriers may impede some methods for screening and prevention of DPN. Wearable and mobile technologies-such as smartphone apps and pressure-sensitive insoles-could help to offset these barriers, yet little is known about the effectiveness of these technologies among individuals with ID.

METHODS

We conducted a scoping review of the databases Embase, PubMed, and Web of Science using search terms for DM, DPN, ID, and technology to diagnose or monitor DPN. Finding a lack of research in this area, we broadened our search terms to include any literature on technology to diagnose or monitor DPN and then applied these findings within the context of ID.

RESULTS

We identified 88 articles; 43 of 88 (48.9%) articles were concerned with gait mechanics or foot pressures. No articles explicitly included individuals with ID as the target population, although three articles involved individuals with other cognitive impairments (two among patients with a history of stroke, one among patients with hemodialysis-related cognitive changes).

CONCLUSIONS

Individuals with ID are not represented in studies using technology to diagnose or monitor DPN. This is a concern given the risk of DM complications among patients with ID and the potential for added benefit of such technologies to reduce barriers to screening and prevention. More studies should investigate how wearable devices can be used among patients with ID.

Improving palliative care for people with intellectual disability: a self-assessment of policies, practices and competencies in care services

BACKGROUND

Providing care for ageing and vulnerable people with intellectual disability (ID) is challenging, and professionals working in ID care often have limited experience in palliative care. The current study provides insight into palliative care practices in ID care services and competencies of professionals and identifies ways to improve palliative care for people with ID.

METHODS

For this study ten services in the Netherlands were recruited that provide care for people with mild to profound ID. Professionals in each of these services conducted a self-assessment of their palliative care policies and practices based on nine core element of palliative care described in the Dutch Quality Framework for Palliative Care. The self-assessment included a medical file review of a total of 100 people with ID who died non-suddenly. In addition, 424 professionals from the services returned a digital questionnaire on palliative care competencies and training needs.

RESULTS

The self-assessments showed that individual care plans were recorded for people with ID and that multidisciplinary teams provided physical, psychological, social and spiritual care. However, other core elements of palliative care, such as cooperation with other organisations and expertise in palliative care, were less present in ID care services. Only half of the services collaborated with regional organisations in palliative care, and most services listed no requirements for the palliative care skills of their professionals. The questionnaire showed that almost 10% of the professionals reported that they were not at all competent in providing palliative care, and 74% felt that they needed training in palliative care. Reported areas for improvement in the provision of palliative care were increasing the quality of palliative care, improving the expertise of professionals and identifying palliative care needs earlier.

CONCLUSIONS

To improve palliative care in ID care services changes are required both in competencies of professionals, and organisational policies and practices. Services should enhance awareness about palliative care for people with ID, strengthen collaboration with palliative care services, and offer training or support for professionals in assessing and meeting the needs of people with ID at the end of life.

The role of mental disorders in precision medicine for diabetes: a narrative review

This narrative review aims to examine the value of addressing mental disorders as part of the care of people with type 1 and type 2 diabetes in terms of four components of precision medicine. First, we review the empirical literature on the role of common mental disorders in the development and outcomes of diabetes (precision prevention and prognostics). We then review interventions that can address mental disorders in individuals with diabetes or at risk of diabetes (precision treatment) and highlight recent studies that have used novel methods to individualise interventions, in person and through applications, based on mental disorders. Additionally, we discuss the use of detailed assessment of mental disorders using, for example, mobile health technologies (precision monitoring). Finally, we discuss future directions in research and practice and challenges to addressing mental disorders as a factor in precision medicine for diabetes. This review shows that several mental disorders are associated with a higher risk of type 2 diabetes and its complications, while there is suggestive evidence indicating that treating some mental disorders could contribute to the prevention of diabetes and improve diabetes outcomes. Using technologically enabled solutions to identify mental disorders could help individuals who stand to benefit from particular treatments. However, there are considerable gaps in knowledge and several challenges to be met before we can stratify treatment recommendations based on mental disorders. Overall, this review demonstrates that addressing mental disorders as a facet of precision medicine could have considerable value for routine diabetes care and has the potential to improve diabetes outcomes.

Cancer-related mortality among people with intellectual disabilities: A nationwide population-based cohort study

Background

Concerns have been raised about access to cancer screening and the timely receipt of cancer care for people with an intellectual disability (ID). However, knowledge about cancer mortality as a potential consequence of these disparities is still limited. This study, therefore, compared cancer‐related mortality patterns between people with and without ID.

Methods

A historical cohort study (2015‐2019) linked the Dutch adult population (approximately 12 million people with an ID prevalence of 1.45%) and mortality registries. Cancer‐related mortality was identified by the underlying cause of death (according to the chapter on neoplasms in the International Classification of Diseases, Tenth Revision). Observed mortality and calculated age‐ and sex‐standardized mortality ratios (SMRs) with 95% confidence intervals (CIs) were reported.

Results

There were 11,102 deaths in the ID population (21.7% cancer‐related; n = 2408) and 730,405 deaths in the general population (31.2%; n = 228,120) available for analysis. Cancer was noted as the cause of death more often among people with ID in comparison with the general population (SMR, 1.48; 95% CI, 1.42‐1.54), particularly in the young age groups. High‐mortality cancers included cancers within the national screening program (SMRs, 1.43‐1.94), digestive cancers (SMRs, 1.24‐2.56), bladder cancer (SMR, 2.07; 95% CI, 1.61‐2.54), and cancers of unknown primary (SMR, 2.48; 95% CI, 2.06‐2.89).

Conclusions

Cancer was reported as the cause of death approximately 1.5 times more often in people with ID compared with the general population. This mortality disparity may indicate adverse effects from inequalities in screening and cancer care experienced by people with ID.

Lay Summary

People with an intellectual disability (ID) may find it challenging to participate in cancer screening or to receive timely cancer care.

To understand potential consequences in terms of mortality, this study compared cancer‐related mortality between people with and without ID in the Netherlands.

Cancer was reported as the cause of death approximately 1.5 times more often among people with ID than others.

Because large differences were found that were related to screening cancers and cancers for which the primary tumor was unknown, this study's results raise concerns about equality in screening practices and cancer care for people with ID.

Cancer is reported as the cause of death approximately 1.5 times more often in people with an intellectual disability compared with those without one. Differences are particularly noted for deaths related to cancers within the national screening program and cancers of unknown primary.

Prevalence and incidence of physical health conditions in people with intellectual disability - a systematic review

OBJECTIVE

To synthesize evidence on the prevalence and incidence of physical health conditions in people with intellectual disability (ID).

METHODS

We searched Medline, PsycInfo, and Embase for eligible studies and extracted the prevalence, incidence, and risk of physical health conditions in people with ID.

RESULTS

Of 131 eligible studies, we synthesized results from 77 moderate- to high-quality studies, which was mainly limited to high-income countries. The highest prevalence estimates were observed for epilepsy, ear and eye disorders, cerebral palsy, obesity, osteoporosis, congenital heart defects, and thyroid disorders. Some conditions were more common in people with a genetic syndrome. Compared with the general population, many health conditions occur more frequently among people with ID, including asthma and diabetes, while some conditions such as non-congenital circulatory diseases and solid cancers occur at the same or lower rate. The latter associations may reflect under-detection.

CONCLUSIONS

People with ID have a health profile more complex than previously known. There is a pressing need for targeted, evidence-informed population health initiatives including preventative programs for this population.

Linking national public services data to estimate the prevalence of intellectual disabilities in The Netherlands: results from an explorative population-based study

OBJECTIVES

Individuals with intellectual disabilities (ID) depend on public services for daily support and medical care; however, this group of individuals can be difficult to identify within population data. This therefore limits the opportunities to accurately estimate the size of the population with ID, monitor trends and tailor public health interventions according to the needs and characteristics of this group. By linking relevant databases, this study sought to identify individuals with ID in national data, to estimate the prevalence of ID based on public service use and to explore how this method can be used to better monitor the population with ID.

STUDY DESIGN

Explorative data linkage study using the Dutch population register and databases from public services accessible with an ID diagnosis.

METHODS

The overall prevalence of ID in the Dutch adult population was estimated, specified by age group and sex, and the identified ID groups were also characterised by their support needs. Participants included the entire adult Dutch population who were alive on 1 January 2015.

RESULTS

After linking databases, 187,149 adults with ID were identified within a population of almost 12.7 million Dutch adults, giving an ID prevalence estimate of 1.45%. Prevalence of ID was higher among males (1.7%) than females (1.2%). Most individuals with ID were identified through the use of residential care services (n = 91,064; 0.7%). Non-residential ID-related care was used by 27,007 individuals (0.2%). Social, employment or income support due to a (mild) ID was received by 69,078 individuals (0.5%); the mean age in these ID groups was between 8 and 10 years which is younger than that in the general Dutch population. ID prevalence declined with increasing age across all ID subgroups.

CONCLUSIONS

The ID prevalence in The Netherlands, as determined by ID-related public service usage, aligns with international estimates. This suggests that national supportive services are accessible and used by individuals with ID. Moreover, this demonstrated that databases from national supportive services can be a useful resource to identify individuals with ID at the population level and can enable structural monitoring of the ID population through linking national databases.
