Prevalence and predictors of co-occurring diabetes and hypertension in community-dwelling older adults

High prevalence of comorbidities in older adult patients with type 2 diabetes: a cross-sectional survey

BACKGROUND

Diabetes is a global health problem, and its incidence and complications increase with the duration of the disease and over time. This increase in complications in older patients can lead to disability and a lower quality of life. This study aimed to investigate the rate of diabetes control and complications in older adults.

METHOD

This was a cross-section of an ongoing cohort of patients with type 2 diabetes mellitus (T2DM) aged 65 years and older. The clinical and laboratory characteristics of older adult patients with T2DM in good and intermediate health conditions were collected between 2010 and 2022.

RESULTS

A total of 2,770 older adult patients with T2DM were enrolled, including 1,530(55.3%) female and 1,240 (44.7%) male participants. Metabolic syndrome, hypertension, and coronary artery disease were the most common comorbidities, affecting 1,889 (71.4%), 1,495 (54.4%), and 786 (29.2%) patients, respectively. Albuminuria was present in 626 (22.6%) patients, while retinopathy was detected in 408 (14.7%) patients, including 6% with proliferative retinopathy. Most patients were treated with oral antidiabetic agents (88.9%), with metformin being the most prescribed medication (85.6%). Statins were prescribed to 71.8% of the patients. The most prescribed antihypertensive medications were angiotensin receptor blockers and angiotensin-converting enzyme inhibitors, prescribed to 54% and 15% of patients, respectively. The hemoglobin A1c (HbA1c) goal (HbA1c < 7.5%) was achieved in 1,350 (56.4%) patients, and the low-density lipoprotein cholesterol (LDL-C) goal (LDL < 100) was achieved in 1,165 (45.6%) patients. Blood pressure control (BP < 140/90) was achieved in 1,755 (65.4%) patients. All three goals were achieved in 278 (10.3%) patients. There were no significant differences in clinical laboratory results and the patients' characteristics based on gender.

CONCLUSION

The rate of progression of complications in older adult patients is higher than the effectiveness of the treatment, indicating the need for increased social support for this age group.

Body mass index and multimorbidity risk: A systematic review and dose-response meta-analysis

OBJECTIVE

To verify the dose-response relationship between body mass index (BMI) and multimorbidity risk.

METHODS

PubMed, CINAHL, and Embase were systematically studied until January 25, 2023. Original articles on BMI and multimorbidity risk were included. Random effects model and dose-response meta-analysis were used to estimate the pooled odds ratio (OR) with 95 % confidence interval (CI). Subgroup analysis was performed to explore potential heterogeneity.

RESULTS

A total of 43 studies involving 969,130 patients (94,978 with multimorbidity) were involved in the meta-analysis. In the longitudinal studies, the pooled results showed that, compared to being a normal BMI, being overweight was much similar with 1.32 times possibility of getting multimorbidity; in persons with obesity the risk was 1.93 times higher; and the risk decreased 0.80 times among underweight persons. Additionally, obesity was 1.75 times as likely to be multimorbidity than those non-obese persons. In the cross-sectional studies, the pooled results demonstrated that persons with overweight and obesity had a 1.38-fold and 2.38-fold risk for multimorbidity, respectively; and the risk decreased 0.90 times among underweight persons compared to those with normal BMI. Besides, obese people are 1.89 times more likely to have multimorbidity than non-obese people. Dose response analysis found the linear connection between BMI and multimorbidity risk (Pnon-linearity=0.762), that for each 1 kg/m2 and 5 kg/m2 increase in BMI, the multimorbidity risk increased by 6 % and 35 %, respectively.

CONCLUSIONS

Multimorbidity increased linearly with an increase in BMI. Clinicians should pay attention to persons with abnormal weight, to help them achieve normal BMI.

DASH diet vs. DASH diet plus physical activity in older patients with type 2 diabetes and high blood pressure: A randomized clinical trial

BACKGROUND AND AIMS

To evaluate the effect of lifestyle modification by adopting a DASH diet, with and without physical activity guidance, on blood pressure, glycemic control, lipid profile, weight, and body composition in older patients with type 2 diabetes mellitus (T2DM) and hypertension.

METHODS AND RESULTS

For this randomized clinical trial, we recruited patients aged 60 years or older with T2DM and uncontrolled hypertension. One group (DASH) received only DASH dietary guidance, while the other group (DASHPED) received dietary guidance and encouragement to walk with a pedometer. Outcomes of interest were (1) blood pressure, (2) physical activity, (3) weight, body mass index (BMI), and body composition, and (4) biochemical variables. Measurements were taken at baseline and 16 weeks after the intervention. We included 35 patients in the analysis. At the end of the study, the DASHPED group had an mean increase in physical activity of 1721 steps/day. Both groups displayed significantly reduced weight, BMI, and waking diastolic pressures on ambulatory blood pressure monitoring after the intervention. A trend of reduced sleeping diastolic pressure was found in the DASHPED group. Changes in weight, BMI, muscle mass, body fat, waist-hip ratio, glycemic control, lipid profile, and insulin sensitivity did not differ between the groups.

CONCLUSION

There was no difference in outcomes between the group that only dieted and the group that also performed increased physical activity, despite a significant increase in exercise. This reinforces the importance of dietary changes in immediate blood pressure control.

Peer Support as Part of Scaling-Up Integrated Care in Patients with Type 2 Diabetes and Arterial Hypertension at the Primary Healthcare Level: A Study Protocol

Introduction

Type 2 diabetes (T2D) and arterial hypertension (AH) are among the greatest challenges facing health systems worldwide and require comprehensive patient-centred care. The key to successful management in chronic patients is self-management support, which was found to be only weakly implemented in Slovenia. The aim of the study is to develop an evidence-based model of peer support for people with T2D and AH at the primary healthcare level in Slovenia, which could represent a potential solution for upgrading integrated care for these patients.

Methods

A prospective interventional, mixed-methods pilot study will begin by recruiting approximately 40 eligible people with T2D and AH through purposive sampling. The participants will receive structured training, led by a specialist nurse, to become trained peer supporters. Each will voluntarily share their knowledge and experience at monthly group meetings with up to 10 people with T2D and AH over a three-month period in the local community. Data will be collected through interviews and focus groups and questionnaires about socio-demographic and clinical data, knowledge about T2D and AH, participants’ quality of life, level of empowerment and acceptability of the intervention.

Expected results

The study will provide an evidence-based model for integrating peer support into the local community. It is expected that the intervention will prove feasible and acceptable with educational, psychosocial and behavioural benefits.

Conclusion

Peer support through empowerment of people with T2D and AH, family members and other informal caregivers in the local community could scale-up the integrated care continuum and contribute to sustainability of the healthcare system.

Social Determinants and Health Disparities Pertaining to Diabetes in Appalachia

CONTEXT

Diabetes poses a significant threat to public health in the United States, with an estimated total prevalence of 37.3 million individuals in 2019, of which 28.7 million were diagnosed and 8.5 million remained undiagnosed. The high prevalence of diabetes imposes a considerable economic burden on the U.S. healthcare system. Appalachian Ohio is disproportionately impacted with southeastern Ohio exhibiting a diabetes prevalence that exceeds the national average by more than twofold and a critical shortage of healthcare providers.

OBJECTIVE

To quantify the associations between diabetes prevalence and incidence in Ohio counties, considering various factors that impact health and quality-of-life outcomes.

METHODS

The data used in this study were obtained from the United States Diabetes Surveillance System (USDSS) on the 88 counties in Ohio. Pearson correlation tests were employed to investigate the relationship between diabetes (prevalence and incidence) and social determinants of health. A t-test and multivariate analysis of variance (MANOVA) test were performed to analyze the disparities in diabetes and social determinants between Appalachian and non-Appalachian counties.

RESULTS

The results of this study demonstrate notable disparities in diabetes prevalence between Appalachian and non-Appalachian counties (P < .001, α = .05). Furthermore, the MANOVA test revealed significant differences between these 2 groups regarding social determinants of health (P < .05).

CONCLUSION

These findings suggest that Appalachian counties may face a disproportionate impact from health-related factors and experience limited access to healthcare services. The data highlight the need for focused efforts to address the specific challenges faced by Appalachian counties. Improving access to healthcare services in the Appalachian region is paramount to ensure equitable healthcare and enhance the overall health outcomes of affected communities.

Increased Mortality Trends in Patients With Chronic Non-communicable Diseases and Comorbid Hypertension in the United States, 2000–2019

Background

According to the Sustainable Development Goals (SDGs), countries are required to reduce the mortality rates of four main non-communicable diseases (NCDs), including cardiovascular diseases (CVDs), diabetes mellitus (DM), chronic respiratory diseases (CRDs), and cancer (CA), by one-third in 2030 from the 2015 level. However, progress fell short of expectations, partly attributed to the high rates of hypertension-related NCD mortality. This study aimed to investigate the mortality trends of SDG-targeted NCDs with comorbid hypertension. In addition, the disparities in mortality rates among different demographic subgroups were further explored.

Methods

Mortality data from 2000 to 2019 were acquired from the Centers for Disease Control and Prevention in the United States. SDG-targeted NCDs were considered the underlying causes of death, and hypertension was considered a multiple cause of death. Permutation tests were performed to determine the time points of Joinpoints for mortality trends. The annual percent changes and average annual percent changes (AAPCs), as well as 95% confidence intervals (CIs), were calculated to demonstrate the temporary trend of mortality rates overall and by age, sex, ethnicity, and region.

Results

The hypertension-related DM, CRD, and CA mortality rates increased over the 20 years, of which the AAPCs were 2.0% (95% CI: 1.4%, 2.6%), 3.2% (95% CI: 2.8%, 3.6%), and 2.1% (95% CI: 1.6%, 2.6%), respectively. Moreover, despite decreasing between 2005 and 2015, the hypertension-related CVD mortality rate increased from 2015 to 2019 [APC: 1.3% (95% CI: 0.7%, 1.9%)]. The increased trends were consistent across most age groups. Mortality rates among men were higher and increased faster than those among women. The hypertension-related CVD, DM, and CA mortality rates among African American people were higher than those among White people. The increased mortality rates in rural areas, especially in rural south, were higher than those in urban areas.

Conclusion

In the United States, the hypertension-related DM, CRD, and CA mortality rates increased between 2000 and 2019, as well as hypertension-related CVD mortality between 2015 and 2019. Disparities existed among different sexes, ethnicities, and areas. Actions to prevent and manage hypertension among patients with NCDs are required to reduce the high mortality rates and minimize disparities.

Effect of Telemedicine on Quality of Care in Patients with Coexisting Hypertension and Diabetes: A Systematic Review and Meta-Analysis

Background: With the development of technology and the need for individualized and continuous support for patients with chronic conditions, telemedicine has been widely used. Despite the potential benefits of telemedicine, little is known about its effect on the quality of care (QoC) in people with hypertension and comorbid diabetes, who face more challenges in disease management than those with hypertension or diabetes alone. This study aimed to examine the effect of telemedicine on QoC for patients with hypertension and comorbid diabetes by synthesizing findings from clinical trials. Methods: This systematic review and meta-analysis were developed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Four major electronic databases from inception to March 2020 were searched. Studies were screened using predetermined criteria. Data were extracted and tabulated into tables. The primary outcomes were QoC indicators, including outcomes (e.g., blood pressure [BP] and glycemic control), process, and experience of care. Quantitative data were pooled and presented in forest plots. Qualitative narratives were also used. Results: Five studies from four clinical trials were included in this review, with intervention durations ranging from 3 to 6 months. Telemedicine significantly decreased BP by 10.4/4.8 mm/Hg, but its effect on glycemic control was inconsistent. Telemedicine also improved experience of care (e.g., patient perception and engagement). Various indicators for process of care were assessed, including medication adherence, BP monitoring, and self-efficacy, with mixed findings. Conclusions: Telemedicine has great potential to improve the QoC, particularly outcomes of care, for patients with hypertension and comorbid diabetes. Health care professionals may consider using available telemedicine to facilitate communication and interaction with their patients, thereby helping them with disease management. Long-term, large-scale studies are needed to test the generalizability and sustainability of the telemedicine programs.

Comparison of clinical outcomes and characteristics between patients with and without hypertension in moyamoya disease

OBJECTIVE

Our study aimed to compare the disparity of patients with moyamoya disease (MMD) between hypertension group and non-hypertension group. And we attempt to explore the risk factors for MMD with hypertension.

METHODS

We retrospectively analyze 542 adult patients with moyamoya disease admitted to our hospital from 2009 to 2016. In view of inclusion criteria, we divided patients with moyamoya disease into two groups (hypertension group and non-hypertension group) and summarized their clinical characteristics. Furthermore, we explore the risk factors for unfavorable outcomes in hypertension group.

RESULTS

Of 542 adult patients with moyamoya disease, we identified 156 patients (28.8%) with hypertension and 386 patients (71.2%) without hypertension. During follow-up, we hold the views that the prognosis of non-hypertension group was obviously better than hypertension group (P = 0.005) and the complications were prone to occurring to patients with hypertension (P = 0.037). In the multivariate analysis, severe hypertension (OR, 2.746; 95% CI, 1.096-6.822; P = 0.031) and no anti-hypertensive medication (OR, 0.342; 95% CI, 0.131-1.895; P = 0.029) were the independent predictors for postoperative unfavorable outcomes. The common surgical modalities of moyamoya disease (direct and indirect bypass) had no significant difference in future unfavorable outcomes prevention in adult MMD patients with hypertension.

CONCLUSIONS

We suggested severe hypertension and no anti-hypertensive medication as the independent risk factors for unfavorable clinical outcomes in adult MMD with hypertension.

Prevalence and Risk of Polypharmacy among Community-Dwelling, Elderly Kuwaiti Patients

OBJECTIVES

To estimate the prevalence of polypharmacy in community-dwelling, older Kuwaiti patients, describe the number and types of drugs used, and identify risk factors associated with polypharmacy.

SUBJECTS AND METHODS

This was a descriptive cross-sectional questionnaire-based survey in which we interviewed 500 community-dwelling Kuwaiti adults over 65 years of age. The data collection occurred during a 4-month period from March to July 2017.

RESULTS

Fifty-two percent (n = 260) of the patients were males, with a mean age of 71.73 ± 5.32 years. The prevalence of polypharmacy (5-8 drugs) and excessive polypharmacy (>8 drugs) was 58.4% (n = 292) and 10.2% (n = 51), respectively. The risk factors associated with an increased number of medicines used were: female gender (p = 0.019), a lower level of education (p = 0.003), a high number of hospital admissions (p = 0.000), clinics visited by the patient (p =0.000), and number of comorbidities (p = 0.000). The most commonly used medications (82.6% of the study population) were blood glucose-lowering agents, excluding insulin. Other commonly used medications were antihypertensive drugs and lipid-modifying agents.

CONCLUSION

A significant sector of the older Kuwaiti patient population has a high prevalence of polypharmacy and is thus exposed to its potential hazards. The current study highlights the need to revise the drug-dispensing policy among community-dwelling, older Kuwaiti people, as well as to initiate educational programs among healthcare practitioners concerning prescribing issues in older individuals.

Impact of social disadvantages in the presence of diabetes at old age

Background

Social disadvantages that start during childhood and continue into the later stages in life may be linked to the presence of diabetes during adulthood. Objective. To analyze whether the presence of social disadvantages in childhood and in the present affects the presence of diabetes in older adults.

Methods

The present study was based on longitudinal data from the third and fourth Mexican Health and Aging Study (MHAS) waves (2012 and 2015). Data on diabetes diagnosis, past (e.g. “no shoes during childhood”) and present (e.g. self-perception of economic status) social disparities, and other covariables were analyzed.

Results

From 8,848 older adults, 21.5% (n = 1903) were classified as prevalent cases (PG), 5.2% (n = 459) as incident cases (IG) and 77.4% (n = 6,486) were free of disease (NDG). The predictor variable “no shoes during childhood” was statistically significant in the model incident versus no diabetes group. Hypertension and body mass index (BMI) were the most relevant covariates as they were statistically significant in the three groups (PG, IG and NDG).

Conclusions

Not having shoes during childhood, an indicator of social disadvantages, is associated with the incidence and prevalence of diabetes in older adults. This suggests that social disadvantages can be a determinant for the presence of chronic diseases in adulthood.
