Diabetes-Associated Factors as Predictors of Nursing Home Admission and Costs in the Elderly Across Europe

Prevalence of Diagnosed Diabetes Among U.S. Adults Aged ≥18 Years With Disabilities, 2021-2022

OBJECTIVE

To compare the prevalence of diagnosed diabetes among U.S. adults with and without disabilities, overall and by subgroups.

RESEARCH DESIGN AND METHODS

We used data on adults aged ≥18 years from the cross-sectional 2021-2022 National Health Interview Survey to report the prevalence of diagnosed diabetes by functional disability status and for each disability type (hearing, seeing, mobility, cognition, self-care, and communication) separately. With use of the Washington Group Short Set on Functioning indicator, disability was defined according to the categories of milder (reporting some difficulty), moderate (reporting a lot of difficulty), and severe (cannot do at all) by disability type. Crude prevalence and age-standardized prevalence of diabetes were also calculated for adults with any difficulty with any disability by age, sex, race/ethnicity, education, insurance, and poverty-to-income ratio.

RESULTS

Diabetes prevalence increased with number of disability types, was lower among adults with no disability (5.8%) than among those with milder (9.5%) or moderate to more severe (18.3%) disability, and was 4.0-10.3 percentage points higher among those with moderate to more severe disability than among those with milder disability for vision, hearing, mobility, and cognitive disabilities. Diabetes prevalence was similar for adults with milder and moderate to more severe self-care and communication disabilities.

CONCLUSIONS

Prevalence of diabetes was higher among adults with any functional disability than without and increased with increasing number of disability types. Adults with multiple disability types, or those who have difficulty with self-care or communication or other moderate to more severe disabilities, may benefit from diabetes prevention programs.

Associations between diabetes and risk of short-term and long-term nursing home stays among older people receiving home care services: A nationwide registry study

BACKGROUND

Older people with diabetes who live at home and receive home care services (HCS) are vulnerable, which may result in a need for more care than the HCS can provide. In this study we aimed to explore associations between pharmacologically treated diabetes and the risk of short-term and long-term nursing home stays (NHS) among older people receiving HCS.

METHODS

This nationwide registry study included older people ≥ 65 years receiving HCS, as registered in the Norwegian Information System for the Nursing and Care Sector (IPLOS) (2010-2014). Data from IPLOS were merged with data from the Norwegian Prescription Database and the Norwegian Patient Registry. Pharmacologically treated diabetes (hereafter referred to as diabetes) was defined based on prescriptions of glucose-lowering drugs (GLD) (≥ 1 prescription in the current or previous year). Persons not prescribed GLD were defined as not having diabetes. Based on Anatomical Therapeutic Chemical (ATC) codes we identified the following subgroups: persons without diabetes, persons using "non-insulin GLD only", "insulin and non-insulin GLD" and "insulin only". An NHS was defined as at least one stay during a given calendar year, where a short-term NHS is temporary, and a long-term NHS is permanent. Log-binomial regression was used to test for differences in NHS and results are reported as risk ratios (RR) with 95% CIs.

RESULTS

Both insulin-treated subgroups had a higher risk of a short-term NHS ("insulin only" users RR 1.06 (CI 1.03-1.09) and "insulin and non-insulin GLD" users RR 1.04 (CI 1.02-1.06)) compared to those without diabetes. In general, persons with diabetes had a lower risk of a long-term NHS than those without diabetes (RR 0.92 (CI 0.89-0.94)). The subgroup using "insulin and non-insulin GLD" had the lowest risk of a long-term NHS (RR 0.86 (CI 0.81-0.91)).

CONCLUSION

Despite a lower risk of a long-term NHS among older people with diabetes, we found an increased risk of a short-term NHS among persons with insulin-treated diabetes who live at home and receive HCS. This calls for attention when planning health care, in order to provide coordinated and individualized care to prevent short-term NHS's.

Mediation role of anxiety on social support and depression among diabetic patients in elderly caring social organizations in China during COVID-19 pandemic: a cross-sectional study

BACKGROUND

Diabetes has become a prominent global public health problem, which is an important cause of death, disease burden, and medical and health economic burden. Previous studies have reported that majority of persons diagnosed with diabetes later presented with psychological and mental health diseases. The study aimed to explore the mediation role of anxiety on social support and depression among diabetic patents in elderly caring social organizations (SOs).

METHODS

A multi-stage stratified cluster random sampling method was used in this cross-sectional study, and a questionnaire consisting of demographic questionnaire, MSPSS, GAD-7, and CES-D-10 was utilized to gather data. SPSS 22.0 and MPLUS 7.4 were used for statistical analysis. Spearman correlation analysis was employed to investigate correlations of key variables. A generalized linear model was used to exam factors associated with depression. Finally, the mediation effect among study variables was investigated by structural equation modeling (SEM).

RESULTS

The average scores of social support, anxiety, and depression were 58.41 ± 14.67, 2.95 ± 3.95, and 7.24 ± 5.53, respectively. The factors of gender, social support, and anxiety were identified as significantly influential factors related to depression among diabetic patients in elderly caring SOs. The effect of social support on depression was significantly mediated by anxiety (β = -0.467, 95%CI: -0.813 to -0.251). Furthermore, anxiety partially mediated the relationship between family support and depression (β = -0.112, 95%CI: -0.229 to -0.012), and anxiety functioned as a complete mediator in the effect of significant others' support and depression (β = -0.135, 95%CI: -0.282 to -0.024).

CONCLUSIONS

The indirect effect of social support on depression through anxiety among diabetic patients in elderly caring SOs was elucidated. Social support played a key role in maintaining and regulating their mental health, particularly from family and significant others. Social support provided by both family and significant others exerted an important influence on maintaining and regulating their mental health. In light of this pathway, the elderly caring SOs should enhance the magnitude of social support from these two sources, thereby diminishing the likelihood of experiencing anxiety and depression.

Integrated health system to assess and manage frailty in community dwelling: Co-design and usability evaluation

Objective

We aimed to co-create and evaluate an integrated system to follow-up frailty in a community dwelling environment and provide a multi-modal tailored intervention. Frailty and dependency among the older population are a major challenge to the sustainability of healthcare systems. Special attention must be paid to the needs and particularities of frail older persons as a vulnerable group.

Methods

To ensure the solution fits all the stakeholders' needs, we performed several participatory design activities with them, such as pluralistic usability walkthroughs, design workshops, usability tests and a pre-pilot. The participants in the activities were older people; their informal carers; and specialized and community care professionals. In total, 48 stakeholders participated.

Results

We created and evaluated an integrated system consisting of four mobile applications and a cloud server, which has been evaluated through a 6-months clinical trial, where secondary endpoints were both usability and user experience evaluation. In total, 10 older adults and 12 healthcare professionals participated in the intervention group using the technological system. Both patients and professionals have positively evaluated their applications.

Conclusion

Both older adults and healthcare professionals have considered the resulted system easy to use and learn, consistent and secure. In general terms, they also would like to keep using it in the future.

Potential Overtreatment and Undertreatment of Type 2 Diabetes Mellitus in Long-Term Care Facilities: A Systematic Review

OBJECTIVE

To investigate the prevalence, outcomes, and factors associated with potential glycemic overtreatment and undertreatment of type 2 diabetes mellitus (T2DM) in long-term care facilities (LTCFs).

DESIGN

Systematic review.

SETTING AND PARTICIPANTS

Residents with T2DM and aged ≥60 years living in LTCFs.

MEASURES

Articles published between January 2000 and September 2020 were retrieved following a systematic search of MEDLINE, EMBASE, Cochrane Library, CINAHL plus, and gray literature. Inclusion criteria were the reporting of (1) potential overtreatment and undertreatment quantitatively defined (implicitly or explicitly) based on hemoglobin A1c (HbA1c) and/or blood glucose; (2) prevalence, outcomes, and associated factors of potential glycemic overtreatment and undertreatment; and (3) the study involved residents of LTCFs.

RESULTS

Fifteen studies were included. Prevalence of potential overtreatment (5%-86%, n = 15 studies) and undertreatment (1.4%-35%, n = 8 studies) varied widely among facilities and geographical locations, and according to definitions used. Prevalence of potential overtreatment was 16%-74% when defined as treatment with a glucose-lowering medication in a resident with ≥1 hypoglycemia risk factor or serious comorbidity, together with a HbA1c <7% (n = 10 studies). Potential undertreatment was commonly defined as residents on glucose-lowering medication having HbA1c >8.5% and the prevalence 1.4%-14.8% (n = 6 studies). No studies prospectively measured resident health outcomes from overtreatment and undertreatment. Potential overtreatment was positively associated with use of oral glucose-lowering medications, dementia diagnosis or dementia severity, and/or need for assistance with activities of daily living (n = 2 studies). Negative association was found between potential overtreatment and use of insulin/combined insulin and oral glucose-lowering medication. No studies reported factors associated with potential undertreatment.

CONCLUSIONS AND IMPLICATIONS

The prevalence of potential glycemic overtreatment and undertreatment varied widely among residents with T2DM depending on the definition(s) used in each study. Longitudinal studies examining associations between glycemic management and health outcomes, and the use of consensus definitions of overtreatment and undertreatment are required to establish findings about actual glycemic overtreatment and undertreatment in LTCFs.

Healthcare Costs Associated with Complications in Patients with Type 2 Diabetes among 1.85 Million Adults in Beijing, China

We aimed to provide reliable regression estimates of expenditures associated with various complications in type 2 diabetics in China. In total, 1,859,039 type 2 diabetes patients with complications were obtained from the Beijing Medical Claim Data for Employees database from 2008 to 2016. We estimated costs for complications using a generalized estimating equation model adjusted for age, sex, and the incidence of various complications. The average total cost for diabetic patients with complications was 17.12 thousand RMB. Prescribed drugs accounted for 63.4% of costs. We observed a significant increase in costs in the first year after the onset of complications. Compared with costs before the incidence of complications, the additional costs per person in the first year and >1 year after the event would be 10,631.16 RMB and 1150.71 RMB for cardiovascular disease, 1017.62 RMB and 653.82 RMB for cerebrovascular disease, and 301.14 RMB and 624.00 RMB for kidney disease, respectively. The estimated coefficients for outpatient visits were relatively lower than those of inpatient visits. Complications in diabetics exert a significant impact on total healthcare costs in the first year of their onset and in subsequent years. Our estimates may assist policymakers in quantifying the economic burden of diabetes complications.

Diabetes management of older adults in nursing homes: A retrospective study

AIM

To examine the diabetes management of older adults in nursing homes.

BACKGROUND

Diabetes is an increasing problem in nursing homes, and diabetes care is defined as a neglected clinical area.

METHODS

A retrospective collected data review of 166 older adults with known diabetes from four nursing homes.

RESULTS

65% older than 75 years had HbA1c levels lower than 7.5% (58 mmol/mol), 74% older than 85 years had HbA1c levels lower than 8% (64 mmol/mol). The HbA1c levels were 7.3% (56 mmol/mol) for those who had three and more chronic disorders and 6.8% (51 mmol/mol) for those who had less than three chronic disorders. Individuals treated with insulin had higher HbA1c levels (p < .001) and glycaemia (p = .002). Age was associated with a number of chronic disorders (p = .031), a number of regularly prescribed medications (p = .038) and a number of medications as needed (p = .009).

CONCLUSIONS

More than half to three quarters have diabetes well-managed. Nevertheless, there is still some potential for improving diabetes care, and these findings warrant further research for improving diabetes management of older adults in nursing homes.

IMPLICATIONS FOR NURSING MANAGEMENT

Interventions designed to promote a healthy lifestyle, documenting individuals' target level and regular monitoring of glycaemia and HbA1c levels may help to improve diabetes management, which may result in better well-being and quality of life for older adults with diabetes in nursing homes.

Predictive factors for entry to long-term residential care in octogenarian Māori and non-Māori in New Zealand, LiLACS NZ cohort

BACKGROUND

Long-term residential care (LTC) supports the most vulnerable and is increasingly relevant with demographic ageing. This study aims to describe entry to LTC and identify predictive factors for older Māori (indigenous people of New Zealand) and non-Māori.

METHODS

LiLACS-NZ cohort project recruited Māori and non-Māori octogenarians resident in a defined geographical area in 2010. This study used multivariable log-binomial regressions to assess factors associated with subsequent entry to LTC including: self-identified ethnicity, demographic characteristics, self-rated health, depressive symptoms and activities of daily living [ADL] as recorded at baseline. LTC entry was identified from: place of residence at LiLACS-NZ interviews, LTC subsidy, needs assessment conducted in LTC, hospital discharge to LTC, and place of death.

RESULTS

Of 937 surveyed at baseline (421 Māori, 516 non-Māori), 77 already in LTC were excluded, leaving 860 participants (mean age 82.6 +/- 2.71 years Māori, 84.6 +/- 0.52 years non-Māori). Over a mean follow-up of 4.9 years, 278 (41% of non-Māori, 22% of Māori) entered LTC; of the 582 who did not, 323 (55%) were still living and may yet enter LTC. In a model including both Māori and non-Māori, independent risks factors for LTC entry were: living alone (RR = 1.52, 95%CI:1.15-2.02), self-rated health poor/fair compared to very good/excellent (RR = 1.40, 95%CI:1.12-1.77), depressive symptoms (RR = 1.28, 95%CI:1.05-1.56) and more dependent ADLs (RR = 1.09, 95%CI:1.05-1.13). For non-Māori compared to Māori the RR was 1.77 (95%CI:1.39-2.23). In a Māori-only model, predictive factors were older age and living alone. For non-Māori, factors were dependence in more ADLs and poor/fair self-rated health.

CONCLUSIONS

Non-Māori participants (predominantly European) entered LTC at almost twice the rate of Māori. Factors differed between Māori and non-Māori. Potentially, the needs, preferences, expectations and/or values may differ correspondingly. Research with different cultural/ethnic groups is required to determine how these differences should inform service development.

Are older patients with diabetes still being overtreated in French long-term care homes?

BACKGROUND

Diabetes management has not been evaluated in French nursing homes (NHs) for 10 years.

OBJECTIVES

The present study aimed to compare the management of diabetes with guidelines in older patients living in NHs.

DESIGN

Observational, retrospective and multicentre study carried out in 13 NH in the Cote d'Or region of France.

SETTINGS AND SUBJECTS

Between January and June 2018, all NH residents older than 65 years and known to have diabetes (n = 148) were included.

METHODS

Epidemiological, clinical and biological data and diabetes characteristics were collected from the medical records.

RESULTS

The average glycated haemoglobin (HbA1C) was 7.2 ± 1.2%. In total, 51% of patients had HbA1C < 7% (n = 70), of which 39 took one or more antidiabetic drugs. In total, 28 of those patients (40%) were at risk of developing hypoglycaemia as a result of their treatment. In all, 44.6% of patients were treated with insulin. Glinides were the most commonly prescribed oral antidiabetic drug (OAD) (27%). Capillary blood glucose monitoring (CBGM) was not carried out daily for 75% of patients taking a potentially hypoglycaemia-inducing OAD.

CONCLUSIONS

We found that glycaemic control was too tight in at least 36.5% of the total population and that 40% of patients with HbA1C < 7% were potentially overtreated. The use of dipeptidyl peptidase 4 (DPP-4) inhibitors was still insufficient, as was CBGM. Avoiding hypoglycaemia is one of the priorities in the management of older patients with diabetes. Therefore, NHs should focus on improving the use of glycaemic targets and antidiabetic drugs that do not induce hypoglycaemia, as well as better monitoring of capillary blood glucose.

Economic evaluation of a multimodal intervention in pre-frail and frail older people with diabetes mellitus: the MID-FRAIL project

Background: The aim of this study was to estimate the incremental cost-utility ratio (ICUR) of a multi-modal intervention in frail and pre-frail subjects aged ≥70 years with type-2 diabetes versus usual care group focused on quality adjusted life years (QALYs) in different European countries. Methods: The MID-FRAIL study was a cluster randomized multicentre trial conducted in seven European countries. A cost-utility analysis was carried out based on this study, conducted from the perspective of the health care system with a time horizon of one year. Univariate and probabilistic analysis were carried out to test the robustness of the results. Results: The cost estimation showed the offsetting health effect of the intervention program on total health care costs. The mean annual health care costs were 25% higher among patients in usual care. The mean incremental QALY gained per patient by the intervention group were 0.053 QALY compared with usual care practice. Conclusions: The MID-FRAIL intervention program showed to be the dominant option in comparison with usual care practice. It saved costs to the health care system and achieved worthwhile health gains. This finding should encourage its implementation, at least, in the trial participant countries.

Monitoring and Intervention Technologies to Manage Diabetic Older Persons: The CAPACITY Case-A Pilot Study

Diabetes Mellitus is a chronic disease with a high prevalence among older people, and it is related to an increased risk of functional and cognitive decline, in addition to classic micro and macrovascular disease and a moderate increase in the risk of death. Technology aimed to improve elder care and quality of life needs to focus in the early detection of decline, monitoring the functional evolution of the individuals and providing ways to foster physical activity, to recommend adequate nutritional habits and to control polypharmacy. But apart from all these core features, some other elements or modules covering disease-specific needs should be added to complement care. In the case of diabetes these functionalities could include control mechanisms for blood glucose and cardiovascular risk factors, specific nutritional recommendations, suited physical activity programs, diabetes-specific educational contents, and self-care recommendations. This research work focuses on those core aspects of the technology, leaving out disease-specific modules. These central technological components have been developed within the scope of two research and innovation projects (FACET and POSITIVE, funded by the EIT-Health), that revolve around the provision of integrated, continuous and coordinated care to frail older population, who are at a high risk of functional decline. Obtained results indicate that a geriatric multimodal intervention is effective for preventing functional decline and for reducing the use of healthcare resources if administered to diabetic pre-frail and frail older persons. And if such intervention is supported by the CAPACITY technological ecosystem, it becomes more efficient.

Cholinesterase inhibitors in patients with diabetes mellitus and dementia: an open-cohort study of ~23 000 patients from the Swedish Dementia Registry

OBJECTIVE

Cholinesterase inhibitors (ChEIs) and memantine are the only approved pharmacological treatments for Alzheimer's disease (AD). Recent literature suggests reductions in cardiovascular burden and risk of stroke in ChEI users. However, the clinical effectiveness of these drugs in patients with diabetes mellitus (DM) and dementia has not been evaluated.

RESEARCH DESIGN AND METHODS

We conducted a registry-based open-cohort study of 22 660 patients diagnosed with AD and mixed-pathology dementia registered in the Swedish Dementia Registry until December 2015. Information on drug use, comorbidity and mortality was extracted using the linkage with the National Patient Registry, the Prescribed Drug Registry and the Cause of Death Registry. In total, 3176 (14%) patients with DM and 19 484 patients without DM were identified. Propensity-score matching, Cox-regression and competing-risk regression models were applied to produce HRs with 95% CIs for differences in all-cause, cardiovascular and diabetes-related mortality rates in ChEI users and non-users.

RESULTS

After matching the ChEI use in patients with DM was associated with 24% all-cause mortality reduction (HR 0.76 (95% CI 0.67 to 0.86)), compared with 20% reduction (0.80 (0.75 to 0.84)) in non-DM users. Donepezil and galantamine use were associated with a reduced mortality in both patients with DM (0.84 (0.74 to 0.96); 0.80 (0.66 to 0.97)) and patients without DM (0.85 (0.80 to 0.90); 0.93 (0.86 to 0.99)). Donepezil was further associated with reduction in cardiovascular mortality, however only in patients without DM (0.84 (0.75 to 0.94)). Rivastigmine lowered mortality only in the whole-cohort analysis and in patients without DM (0.82 (0.75 to 0.89)). Moreover, ChEI use was associated with 48% reduction in diabetes-related mortality (HR 0.52 (0.32 to 0.87)) in the whole-cohort analysis. Last, low and high doses were associated with similar benefit.

CONCLUSIONS

We found reductions in mortality in patients with DM and AD or mixed-pathology dementia treated with ChEIs, specifically donepezil and galantamine were associated with largest benefit. Future studies should evaluate whether ChEIs help maintain self-management of diabetes in patients with dementia.

Developing and validating models for predicting nursing home admission using only RAI-HC instrument data

OBJECTIVE

In recent years research has identified important predictors for nursing home admission (NHA). However, as far as we know, the previous risk models use complex variable sets from many sources and the output is a single risk value. The objective of this study was to develop an NHA risk model with a variable set from single data source and richer output information.

METHODS

In this study, we developed a model selecting variables only from the RAI-HC (Resident Assessment Instrument - Home Care) system. Furthermore, we used principal component analysis and K-means clustering to target proper interventions for high-risk clients.

RESULTS

The performance of the model was close to the complex previous model (recall [Formula: see text] vs. [Formula: see text] and specificity [Formula: see text] vs. [Formula: see text]). For the risk clients, three intervention clusters (deficiency in physical functionality, deficiency in cognitive functionality and depression and mood disorders) were found.

CONCLUSION

The NHA risk model and intervention clusters are important because they enable the identification of proper interventions for the right clients. The fact that the model with RAI-HC data alone was accurate enough simplifies the integration of the NHA risk model into practice because it uses data from one system and the algorithm can be integrated easily into the source system.

Lower dietary variety is a relevant factor for malnutrition in older Japanese home-care recipients: a cross-sectional study

Background

Nutritional status of the older people is affected by various life-style factors. Although dietary habit is one of the life-style factors, it is unknown which of older home-care recipients’ dietary habits are associated with malnutrition.

The purpose of this study was to examine the association of dietary variety, as an evaluation index for dietary habits, with malnutrition in Japanese older home-care recipients.

Methods

This cross-sectional study was conducted in a single city, Hyogo Prefecture, Japan between July and October 2016. Three hundred thirty-three community-dwelling older care recipients (aged 65 years or older who were receiving home-visit nursing care services) were enrolled. Their nutritional status (Mini Nutritional Assessment®-short form: MNA®-SF), dietary variety (Food frequency score [FFS]), socio-demographic characteristics (age, sex, marital status, etc.), health indicators (comorbidity [Charlson Comorbidity Index] and dysphagia status [Dysphagia Severity Scale]) were assessed. The participants were classified into two groups: malnourished (0–7 points) and non-malnourished (8–14 points), according to their MNA®-SF scores. Multivariate logistic regression analysis was used to examine the factors associated with malnutrition.

Results

A total of 317 participants were analyzed (118 men, 199 women, median age: 84 years). Compared to the fourth (highest) quartile of FFS, odds ratios (OR) (95% confidence intervals [CI]) of the third, second, and first (lowest) quartiles of FFS were 1.08 (0.42–2.80), 1.29 (0.56–2.98), and 2.30 (1.02–5.19), respectively (p for trend = 0.049). Higher Charlson Comorbidity Index score and the presence of dysphagia were also significantly associated with malnutrition (OR: 2.08, 95% CI: 1.08–4.00 and OR: 3.86, 95% CI: 2.08–7.17, respectively).

Conclusion

Lower dietary variety was significantly associated with malnutrition in Japanese older home-care recipients.

Health systems strengthening for noncommunicable disease control and healthy aging: integrated actions in Aruba and Curaçao

Caribbean countries are experiencing social, epidemiological, and demographic transitions shaped by the growing elderly population and the rise of noncommunicable diseases (NCDs)-now responsible for 78% of all deaths. These circumstances demand rethinking the model of care to improve health outcomes and build more sustainable health systems with new orientations in policy, service delivery, organization, training, technology, and financing. Policy must be aimed towards healthy living, leveraging interventions that ensure healthy aging. The health system must proactively structure interventions to reduce the incidence of new NCD cases and to prevent related complications. Interventions should be focused on optimizing the individual's capacity, functional ability, and autonomy within adapted environments, as well as with the necessary preventive, long-term care, self-care, community care, and health system support.

Socioeconomic differences in the associations between diabetes and hospital admission and mortality among older adults in Europe

The aim of this study is to explain the trends in socioeconomic inequality and diabetes outcomes in terms of hospital admission and death in old European people. The sample includes 73,301 individuals, across 16 European countries taken from the Survey of Health, Ageing and Retirement in Europe (SHARE). People being diagnosed of diabetes were more likely to be admitted to hospital than those without diabetes, although its effect dropped after controlling for clinical and functional complications. Largest asscociations were observed in women, people aged 50-65 years old, with medium educational level and medium household income. Diabetes was significant and positively related to mortality in the whole sample. Diabetes is significantly associated with mortality risk especially in males, oldest old people, low education and medium income people. These findings have important implications for public policies to reduce socioeconomic-related health inequalities.

Is quality of life different between diabetic and non-diabetic people? The importance of cardiovascular risks

Background

To analyse and compare the impact of cardiovascular risk factors and disease on health-related quality of life (HRQoL) in people with and without diabetes living in the community.

Methods

We used data of 1,905 people with diabetes and 19,031 people without diabetes from the last Spanish National Health Survey (years 2011–2012). The HRQoL instrument used was the EuroQol 5D-5L, based on time trade-off scores. Matching methods were used to assess any differences in the HRQoL in people with and without diabetes with the same characteristics (age, gender, education level, and healthy lifestyle), according to cardiovascular risk factors and diseases. Disparities were also analysed for every dimension of HRQoL: mobility, daily activities, personal care, pain/discomfort, and anxiety/depression.

Results

There were no significant differences in time trade-off scores between people with and without diabetes when cardiovascular risk factors or established cardiovascular disease were not present. However, when cardiovascular risk factors were present, the HRQoL score was significantly lower in people with diabetes than in those without. This difference was indeed greater when cardiovascular diseases were present. More precisely, people with diabetes and any of the cardiovascular risk factors, who have not yet developed any cardiovascular disease, report lower HRQoL, 0.046 TTO score points over 1 (7.93 over 100 in the VAS score) compared to those without diabetes, and 0.14 TTO score points of difference (14.61 over 100 in the VAS score) if cardiovascular diseases were present. In fact, when the three risk factors were present in people with diabetes, HRQoL was significantly lower (0.10 TTO score points over 1 and 10.86 points over 100 in VAS score), obesity being the most influential risk factor.

Conclusions

The presence of established cardiovascular disease and/or cardiovascular risk factors, specially obesity, account for impaired quality of life in people with diabetes.
