Relationship between glycemic control and depression among American Indians in the Strong Heart Study

Depression, physical activity, and incident cardiovascular disease among American Indians: The strong heart family study

Background

Little is known about the relationship of depression with incident cardiovascular disease (CVD) among American Indians (AIs), a population with a high burden of depressive symptoms and CVD. In this study, we examined the association of depressive symptoms with CVD risk among AIs and assessed whether an objective marker of ambulatory activity influenced the relationship.

Methods

The study comprised participants from the Strong Heart Family Study, a longitudinal study of CVD risk among AIs free of CVD at baseline (2001-2003) and who participated in a follow-up examination (n = 2209). The Center for Epidemiologic Studies of Depression Scale (CES-D) was used to assess depressive symptoms and depressive affect. Ambulatory activity was measured using Accusplit AE120 pedometers. Incident CVD was defined as new myocardial infarction, coronary heart disease, or stroke (through 2017). Generalized estimating equations were used to examine the association of depressive symptoms with incident CVD.

Results

27.5% of participants reported moderate or severe depressive symptoms at baseline and 262 participants developed CVD during follow-up. Compared to participants who reported no depressive symptoms, the odds ratios for developing CVD among those who reported mild, moderate, or severe symptoms were: 1.19 (95% CI: 0.76, 1.85), 1.61 (95% CI: 1.09, 2.37), and 1.71 (95% CI: 1.01, 2.91), respectively. Adjustment for activity did not alter findings.

Limitations

CES-D is a tool used to identify individuals with depressive symptoms and not a measure of clinical depression.

Conclusion

Higher levels of reported depressive symptoms were positively associated with CVD risk in a large cohort of AIs.

Increased Levels of HbA1c in Individuals with Type 2 Diabetes and Depression: A Meta-Analysis of 34 Studies with 68,398 Participants

Glycosylated hemoglobin is used to diagnose type 2 diabetes mellitus and assess metabolic control. Depression itself has been associated with high levels of HbA1c in individuals with T2DM. The association between diabetes and depression suggests the usefulness of determining HbA1c as a biological marker of depressive symptoms. The aim of this study was to determine HbA1c levels in individuals with T2DM with vs. without depression. Additionally, we analyzed the influence of pharmacological treatments, time of evolution, and complications of disease. We performed a literature search in different databases published up to January 2020. A total of 34 articles were included. Our results showed that individuals with T2DM with depression showed increased levels of HbA1c in comparison to individuals with T2DM without depression (d = 0.18, 95% CI: 0.12−0.29, p(Z) < 0.001; I2 = 85.00). We also found that HbA1c levels remained elevated in individuals with T2DM with depression who were taking hypoglycemic drugs (d = 0.20 95% CI: 0.11−0.30, p(Z) < 0.001; I2 = 86.80), in individuals with less than 10 years of evolution (d = 0.17 95% CI: 0.09−0.26, p(Z) = 0.001; I2 = 66.03) and in individuals with complications of the disease (d = 0.17, 95% CI: 0.07−0.26, p(Z) < 0.001; I2 = 58.41). Our results show that HbA1c levels in individuals with T2DM with depression are significantly increased compared to controls with T2DM without depression. Additionally, these levels remained elevated in individuals who were taking hypoglycemic drugs, those with less than 10 years of disease evolution, and those with complications related to diabetes. It is necessary to examine the existence of a diabetes−HbA1c−depression connection.

Synergistic effects of depression and obesity on type 2 diabetes incidence in Chinese adults

BACKGROUND

Cross-sectional studies have supported the association among depression, obesity, and type 2 diabetes, but the causality remains controversial in Chinese adults. In this longitudinal study, we evaluated the synergistic effect of depression and obesity on the risk of type 2 diabetes.

METHODS

This study included 2809 participants randomly selected from the Qingdao Diabetes Prevention Program, and their type 2 diabetes incidence was determined over a follow-up period of 3 years. The WHO 2006 criteria and the Zung Self-Rating Depression Scale score were employed to identify type 2 diabetes and depression at baseline, respectively. Multivariable-adjusted logistic regression was used to evaluate the synergistic effects of depression and obesity indicators on type 2 diabetes, with adjustment for age, sex, family history of diabetes, and other potential risk factors.

RESULTS

During 3-year follow-up, 316 new incident cases were identified. The relative risk and 95% confidence interval of depression for diabetes incidence was 1.52 (1.05-2.21), after controlling for potential confounders. Sensitivity analysis showed that depression was significantly associated with diabetes incidence in women, younger people, and obese people (1.82 [1.14-2.92], 1.94 [1.25-3.02], and 4.29 [1.44-12.78], respectively]. The synergistic effects of positive depression and body mass index ≥30 kg/m² on type 2 diabetes incidence were observed, with a synergy index of 5.49 (1.75-17.19).

CONCLUSIONS

Depression was associated with a 52% increased risk of type 2 diabetes incidence and exerts synergistic effects with obesity on diabetes incidence in Chinese adults. Early identification and intervention for depression and obesity can reduce the risk of diabetes.

Evaluation of factors related to glycaemic control among South Korean patients with type 2 diabetes

Aims

To examine specific self‐care behaviours, depression, and diabetes‐related stress among South Korean patients with type 2 diabetes and to evaluate whether these factors are related to glycaemic control.

Methods

This cross‐sectional study included 171 patients with type 2 diabetes who visited an endocrinology clinic. A structured questionnaire and electronic medical records were used to collect data regarding self‐care behaviours, depression, diabetes‐related distress, and glycaemic control between May 2015 and July 2015.

Results

Compared with the group with good glycaemic control, the group with poor glycaemic control had significantly lower values for medication adherence and significantly greater values for regimen‐related distress. Depression was not significantly associated with glycaemic control. In logistic regression analysis, only medication adherence was independently associated with glycaemic control.

Conclusions

Medication adherence should be continuously emphasized and monitored in clinical practice to effectively manage glycaemic control among patients with type 2 diabetes. Furthermore, consideration of diabetes‐related distress may help improve glycaemic control among patients with type 2 diabetes.

What is already known about this topic?

To control glycaemic levels, patients with type 2 diabetes should practice self‐care (medication, diet, exercise, and blood glucose monitoring). However, patients with type 2 diabetes complain that self‐care is complicated and difficult to follow in daily life.

Many people with type 2 diabetes experience high levels of depression and distress stemming from concerns associated with diabetes and its management.

Diabetes‐related distress, depression, and self‐care behaviours have been thought to be related to glycaemic levels. However, data from cross‐sectional studies on this relationship are not consistent. There are few studies on these variables in patients with type 2 diabetes in South Korea.

What this paper adds?

Diabetes‐related distress was only associated with glycaemic control, whereas depression and self‐care behaviours were not significantly associated with glycaemic control among South Korean patients with type 2 diabetes.

We subcategorized diabetes‐related distress into emotional burden, physician‐related distress, regimen‐related distress, and diabetes‐related interpersonal distress, but only regimen‐related distress was significantly associated with glycaemic control. We subcategorized self‐care behaviours into medication, diet, exercise, and blood glucose monitoring, but only medication was significantly associated with glycaemic control.

Our findings suggest that among patients with type 2 diabetes, glycaemic control was only associated with medication adherence among the self‐care behaviours that we evaluated.

The implications of this paper:

In the clinical setting, health‐care providers, including nurses, should assess and address regimen‐related distress as this is a known barrier to accomplishment of optimal glycaemic control.

Health‐care providers, including nurses, should explain the need for medication adherence to patients so that they can manage type 2 diabetes, and they should continuously reassess adherence to medications.

Future research in diabetes should include assessment of specific domains of diabetes‐related distress and specific domains of self‐care, along with measures of blood glucose control.

Depressive symptoms are associated with leukocyte telomere length in American Indians: findings from the Strong Heart Family Study

Patients with depression have an increased risk for many aging-related disorders, but the biological mechanisms underlying this link remain to be determined. Here we examined the association between depressive symptoms and leukocyte telomere length (LTL), a marker of biological aging, among 2,175 American Indians participating in the Strong Heart Family Study. Depressive symptoms were assessed by the Center for Epidemiologic Studies of Depression Scale (CES-D), which was categorized into four levels: none (< 10), mild (10-15), moderate (16-24), and severe (> 24). LTL (T/S ratio) was quantified by qPCR. The association between depressive symptoms and LTL was examined by multivariate generalized estimating equation models, adjusting for sociodemographic factors, lifestyle factors, and chronic conditions. Results showed that individuals with a higher level of depressive symptoms had shorter LTL. Specifically, LTL in participants reporting none, mild, moderate, and severe depressive symptoms were 1.000, 0.999, 0.988, and 0.966, respectively (P for trend = 0.0278). Moreover, gender appears to modulate the effect of reported depressive symptoms that fall in the severe range (CES-D > 24) on LTL (P for interaction = 0.0346). Our results suggest that depressive symptoms may accelerate biological aging through pathways beyond traditional risk factors in American Indians.

Association of depressive symptomology and psychological trauma with diabetes control among older American Indian women: Does social support matter?

AIMS

Among older American Indian women with type 2 diabetes (T2DM), we examined the association between mental health and T2DM control and if social support modifies the association.

METHODS

Survey data were linked to T2DM medical record information. Mental health measures were the Center for Epidemiologic Studies - Depression Scale and the National Anxiety Disorders Screening Day instrument. T2DM control was all HbA1c values taken post mental health measures.

RESULTS

There was not a significant association between depressive symptomatology and higher HbA1c although increased depressive symptomatology was associated with higher HbA1c values among participants with low social support. There was a significant association between psychological trauma and higher HbA1c values 12months [mean 7.5, 95% CI 7.0-8.0 for no trauma vs. mean 7.0, 95% CI 6.3-7.6 for trauma with no symptoms vs. mean 8.4, 95% CI 7.7-9.1 for trauma with ≥1 symptom(s)] and 6months later [mean 7.2, 95% CI 6.7-7.7 for no trauma vs. mean HbA1c 6.8, 95% CI 6.2-7.4 for trauma with no symptoms vs. mean 8.4, 95% CI 7.6-9.2 for trauma with ≥1 symptom(s)]. High social support attenuated the association between psychological trauma and HbA1c values.

CONCLUSIONS

T2DM programs may consider activities that would strengthen participants' social support and thereby building on an intrinsic community strength.

Emotional and Behavioral Aspects of Diabetes in American Indians/Alaska Natives

American Indians and Alaska Natives (AI/ANs) bear a disproportionate burden of diabetes and associated long-term complications. Behavioral interventions play a vital role in promoting diabetes medical and psychological outcomes, yet the development of interventions for AI/AN communities has been limited. A systematic review was conducted of studies focused on the psychosocial and behavioral aspects of diagnosed diabetes among AI/ANs. Ovid and PubMed databases and published reference lists were searched for articles published between 1987 and 2014 that related to the psychosocial and behavioral aspects of type 1 or type 2 diabetes in the AI/AN population. Twenty studies were identified that met the inclusion criteria. Nineteen studies were observational and one study was intervention based. Two of the studies used community-based participatory research methodology. Of the 20 studies, 2 discussed cultural influences associated with diabetes self-management and 10 identified the specific tribes that participated in the study. Tribal affiliations among the studies were broad with the number of AI/AN participants in each study ranging from 30 to 23,529 participants. Emotional and behavioral topics found in the literature were adherence ( n = 2), depression ( n = 9), physical activity ( n = 3), psychosocial barriers ( n = 1), social support ( n = 3), and stress ( n = 2). Relatively few studies were identified using AI/AN populations over a 27-year period. This is in stark contrast to what is known about the prevalence and burden that type 1 and type 2 diabetes mellitus place on AI/AN communities. Future research should promote community engagement through the use of community-based participatory research methodologies, seek to further understand and describe the emotional and behavioral context for diabetes self-management in this population, and develop and test innovative interventions to promote the best possible diabetes outcomes.

Mental health service and provider preference among American Indians with type 2 diabetes

In this study, we investigated mental health service and provider preferences of American Indian adults with type 2 diabetes from two tribes in the northern Midwest. Preferences were determined and compared by participant characteristics. After controlling for other factors, living on reservation lands was associated with increased odds of Native provider preference, and decreased odds of biomedical service preference. Anxiety also was associated with decreased odds of biomedical service preference. Spiritual activity engagement and past health care discrimination were associated with increased odds of traditional service preference. We discuss implications for the types of mental health services offered and characteristics of providers who are recruited for tribal communities.

Attitudes Toward Mental Health Services Among American Indians by Two Age Groups

This study examined determinants of attitudes toward mental health services with a sample of American Indian younger-old-adults (aged 50-64, n = 158) and American Indian older-old adults (aged 65 and older, n = 69). Adapting Andersen's behavioral model of healthcare utilization, predisposing factors, mental health needs, and enabling factors were considered as potential predictors. Female and those with higher levels of social support tend to report more positive attitudes toward mental health services. Culture-influenced personal belief was associated with negative attitudes toward mental health services among American Indian younger-old -adults. Age and higher chronic medical conditions were significantly related to negative attitudes toward mental health services. Health insurance was positively associated with positive attitudes toward mental health services in the American Indian older-old adults. Findings indicate that practitioners should engage how culture, social support, and chronic conditions influence the response to mental health needs when working with older American Indians.

Stressors, Coping Resources, and Depressive Symptoms among Rural American Indian Older Adults

The purpose of this study was to examine the associations of physical health stressors and coping resources with depressive symptoms among American Indian older adults age 50 years or older. The study used a convenience sample of 227 rural American Indian older adults. A hierarchical multiple regression tested three sets of predictors on depressive symptoms: (a) sociodemographics, (b) physical health stressors (functional disability and chronic medical conditions), and (c) coping resources (social support and spirituality). Most participants reported little difficulty in performing daily activities (e.g., eating, dressing, traveling, and managing money), while presenting over two types of chronic medical conditions. Depressive symptoms were predicted by higher scores on perceived social support and lower scores on functional disability; women and those having no health insurance also had higher levels of depressive symptoms. Findings suggest that social work practitioners should engage family and community support, advocate for access to adequate health care, and attend to women's unique circumstances and needs when working with American Indian older adults.

Serious Psychological Distress and Diabetes Management among American Indians and Alaska Natives

OBJECTIVE

Our study examined associations between serious psychological distress and blood glucose level (HbA1c) and body mass index (BMI) among American Indian and Alaska Native (AI/AN) participants in a cardiovascular disease prevention program.

DESIGN

Using linear regression, we assessed the relationships between serious psychological distress and HbA1c and BMI at baseline and one year later. SETTING, PARTICIPANTS, AND INTERVENTION: AI/AN participants were aged 18 years, diagnosed with type 2 diabetes, and enrolled in the Special Diabetes Project for Indians Healthy Heart Project.

MAIN OUTCOME MEASURES

Outcomes were percentage of HbA1c and BMI, measured at enrollment and first annual exam. Both outcomes were continuous measures in all analyses.

RESULTS

Serious psychological distress was associated at baseline with increased HbA1c in the unadjusted and adjusted models (adjusted b = .17%, P < 0.01). Serious psychological distress also was associated at baseline with increased BMI (.635 kg/m2, P = .01) and at one year with increased BMI (0.174 kg/m2, P = .01) in the unadjusted model. After adjustment for demographic and health characteristics, these relationships were no longer significant.

CONCLUSIONS

Cross-sectional baseline findings are consistent with existing literature. One-year findings suggest need for further inquiry into mediators of psychological distress and examination of additional diabetes-specific health outcomes. Additional years of observation may be needed to disentangle relationships between serious psychological distress and BMI.

Mental Health in Diabetes Prevention and Intervention Programs in American Indian/Alaska Native Communities

American Indian and Alaska Natives youth and adults experience higher rates of type 2 diabetes and mental health problems than the general United States population. Few studies have explored the relationship other than detail the two issues independently. The present review aims to identify programs that seek to prevent/treat type 2 diabetes and mental health disorders in the American Indian and Alaska Native population. Available programs were reviewed for AI/AN adults and youth who suffer with both. As part of the review process, databases were searched for peer reviewed published studies. It was found that very few programs effectively incorporate mental health into the existing diabetes program. Four recommendations for future research are offered based on this literature review.

Depression, self-esteem, diabetes care and self-care behaviors among middle-aged and older Mexicans

AIMS

Examine the associations of depression and self-esteem on self-care activities and care received among Mexicans with diabetes.

METHODS

Using data from the Mexican Nutrition and Health Survey 2012, logistic regression models were fit to test the associations between each self-care activity and diabetes care, and self-esteem and depression.

RESULTS

People with low self-esteem were less likely to follow a diet, but no other associations were found. Contrary to what was expected, there were no relationships between depression and quality of care received or self-care behaviors.

CONCLUSION

Current findings support the importance of looking at mental health and emotional state among older adults with diabetes. Future studies should explore the relationship between different psychological barriers to proper diabetes management.

Glucose Levels and Depression in Hispanic Patients Admitted to the Cardiovascular Intensive Care Unit

Depression is frequently associated with diabetes mellitus (DM) and may worsen DM-related morbidity and mortality. We determined the potential association of glucose levels with depression in Hispanic patients admitted to the Cardiovascular Intensive Care Unit. Patients were given the Center for Epidemiologic Studies—Depression scale survey within 24 hours of admission. Glycated hemoglobin and fasting blood glucose levels within 30 days of admission were extracted. The HbA1c levels remained significantly associated with both presence of depression and depression levels. Histories of DM, myocardial infarction, and percutaneous coronary intervention as well as baseline brain natriuretic peptide levels were also significantly associated with depression levels. The presence of a significant association between glucose levels and depression in Hispanic patients indicates that there is a need for optimal management of glycemic levels. This may then lead to better health outcomes in Hispanics with cardiovascular disease.

Winter depression and diabetes

Depression is a common and often harmful disorder, which is frequently associated with the winter season. Research has shown a link between type 2 diabetes mellitus and depression. Furthermore, diabetics with depression have a higher rate of adverse outcomes. Little has been published regarding the seasonality of depression in diabetics. The case report described in this article concerns a 65-year-old woman with type 2 diabetes and a history of winter depression. Current evidence-based management options are reviewed.

Psychological trauma symptoms and Type 2 diabetes prevalence, glucose control, and treatment modality among American Indians in the Strong Heart Family Study

AIMS

The aims of this paper are to examine the relationship between psychological trauma symptoms and Type 2 diabetes prevalence, glucose control, and treatment modality among 3776 American Indians in Phase V of the Strong Heart Family Study.

METHODS

This cross-sectional analysis measured psychological trauma symptoms using the National Anxiety Disorder Screening Day instrument, diabetes by American Diabetes Association criteria, and treatment modality by four categories: no medication, oral medication only, insulin only, or both oral medication and insulin. We used binary logistic regression to evaluate the association between psychological trauma symptoms and diabetes prevalence. We used ordinary least squares regression to evaluate the association between psychological trauma symptoms and glucose control. We used binary logistic regression to model the association of psychological trauma symptoms with treatment modality.

RESULTS

Neither diabetes prevalence (22%-31%; p=0.19) nor control (8.0-8.6; p=0.25) varied significantly by psychological trauma symptoms categories. However, diabetes treatment modality was associated with psychological trauma symptoms categories, as people with greater burden used either no medication, or both oral and insulin medications (odds ratio=3.1, p<0.001).

CONCLUSIONS

The positive relationship between treatment modality and psychological trauma symptoms suggests future research investigate patient and provider treatment decision making.

Spousal loss and health in late life: moving beyond emotional trauma

OBJECTIVE

This study queries the linkage of older adults' spousal loss to multiple dimensions of their health.

METHODS

Data are from the 2005-2006 National Social Life, Health, and Aging Project, nationally representative of U.S. adults ages 57 to 85. Analyses examine associations of spousal loss and time since loss with multiple health dimensions.

RESULTS

Spousal loss is linked to a system of mental, social, behavioral, and biological issues, consistent with a stress-induced weathering process. Biological problems are more uniformly associated with women's than men's loss. While emotional sequelae may partially subside with time, a range of other outcomes remain worse even among individuals a decade or more past loss, than those with current partners.

DISCUSSION

Older adults' spousal loss influences multiple dimensions of their health. Gender differences in biological linkages suggest women's greater physiological vulnerability to this weathering event. Effects of loss are long term rather than transient, especially with biological conditions.

Environmental risk conditions and pathways to cardiometabolic diseases in indigenous populations

This review examines environments in relation to cardiometabolic diseases in Indigenous populations in developed countries. Environmental factors are framed in terms of context (features of places) and composition (features of populations). Indigenous peoples are seen to have endured sociopolitical marginalization and material disadvantage spanning generations. Past adverse collective experiences, modified by culture, are reflected by current heterogeneity in environmental context and composition. As risk conditions, unfavorable contextual and compositional exposures influence the expression of cardiometabolic risk for individuals. Minimal research has evaluated heterogeneity in risk conditions against heterogeneity in cardiometabolic diseases between or within Indigenous populations. Thus far, the features of populations, not of places themselves, have been implicated in relation to cardiometabolic diseases. Behavioral, psychosocial, and stress-axis pathways may explain the relationships between risk conditions and cardiometabolic diseases. Implications of environmental factors and their pathways as well as important research needs are discussed in relation to ecological prevention to reduce cardiometabolic diseases.
