Depression, diabetes, and glycemic control in an American Indian community

Screening depression and anxiety in Indigenous peoples: A global scoping review

Indigenous peoples' worldviews are intricately interconnected and interrelated with their communities and the environments in which they live. Their worldviews also manifest in a holistic view of health and well-being, which contrasts with those of the dominant western biomedical model. However, screening depression and/or anxiety in Indigenous peoples often occurs using standard western tools. Understandably, the cultural appropriateness of these tools has been questioned. The purpose of this scoping review was to map the literature that used any type of tool to screen depression or anxiety in Indigenous adults globally. A systematic scoping review method was used to search databases including, but not limited to, CINAHL, PubMed, Scopus and Google. Database-specific search terms associated with Indigenous peoples, depression and anxiety, and screening tools were used to identify literature. In addition, citation searches of related systematic reviews and relevant websites were conducted. The data set was limited to English language publications since database inception. Fifty-four publications met the review's inclusion criteria. Most studies were completed in community settings using standard western depression and anxiety screening tools. Thirty-three different tools were identified, with the Patient Health Questionnaire-9 being the most frequently used. The review's findings are concerning given repeated calls for culturally appropriate screening tools to be used with Indigenous peoples. Although there has been some work to cross-culturally adapt depression screening tools for specific Indigenous populations, clearly more clinicians and researchers need to be aware of, and use, culturally appropriate approaches to screening.

Comparison of the incidence of depression before and after endovascular treatment in patients with lower limb peripheral artery disease

Depression is a chronic illness that affects mood, physical health, and overall vitality and quality of life. Depression has been associated with an increased risk of all-cause and cardiovascular mortality among patients with peripheral arterial disease (PAD). Therefore, this study aimed to compare the incidence of depression before and after endovascular treatment in patients with lower limb PAD. This is an important clinical issue considering the worldwide increase in PAD with the aging population and the known negative impact of depression on recovery. This was a retrospective sub-analysis of data from the Tokyo Peripheral Vascular Intervention Study using the TOMA-CODE registry. The presence and extent of depressive symptoms were evaluated using the patient health questionnaire (PHQ-9), with a depressive tendency score of ≥ 5. The PHQ-9 score was evaluated before endovascular treatment (EVT) and at 4 (± 1) weeks after EVT. The study population consisted of 87 patients who completed the PHQ-9 before EVT, with 76 completing the post-EVT PHQ-9. Of these 76, 19 had a pre-EVT score ≥ 5. Overall, there was no difference in the pre- and post-EVT scores (P = 0.091). There was no significant change in the 19 patients with a pre-EVT score ≥ 5 (mean 9.2 ± 4.4); however, there was a tendency to improve in the pre- to post-EVT score (mean, 6.9 ± 5.2; P = 0.059). Diabetes was a significant negative factor for pre- to post-EVT score improvement (P = 0.023). Overall, symptoms of depression showed the tendency to improve at 30 days post-EVT. However, diabetes was associated with lower improvement in symptoms.

Epidemiology of Type 2 Diabetes in Indigenous Communities in the United States

PURPOSE OF REVIEW

The present review focuses on the epidemiology of type 2 diabetes (T2D) in Indigenous communities in the continental United States (U.S.)-including disease prevention and management-and discusses special considerations in conducting research with Indigenous communities.

RECENT FINDINGS

Previous studies have reported the disparately high prevalence of diabetes, especially T2D, among Indigenous peoples in the U.S. The high prevalence and incidence of early-onset T2D in Indigenous youth relative to that of all youth in the U.S. population pose challenges to the prevention of complications of diabetes. Behavioral, dietary, lifestyle, and genetic factors associated with T2D in Indigenous communities are often investigated. More limited is the discussion of the historical and ongoing consequences of colonization and displacement that impact the aforementioned risk factors. Future research is necessary to assess community-specific needs with respect to diabetes prevention and management across the diversity of Indigenous communities in the U.S.

American Indian Alcohol Use from a Sex-Specific Wellness Approach: Exploring Its Associated Physical, Behavioral, and Mental Risk and Protective Factors

PURPOSE

The top causes of death for American Indians (AIs), including heart and liver disease, are associated with alcohol use. Using the culturally based Framework of Historical Oppression, Resilience, and Transcendence (FHORT), the purpose of this article was to examine AI alcohol use from a sex-specific wellness approach, exploring its associated physical, behavioral, and mental risk and protective factors.

METHOD

Data were drawn from a cross-sectional survey with 479 AI adults in South Dakota. We employed a series of multiple hierarchical regression analyses to assess the associations of demographic (sex, age, marital status, income, and educational attainment), physical (Body Mass Index and cardiovascular risk), behavioral (smoking and health self-efficacy) and mental (depressive symptoms) factors with alcohol use.

RESULTS

Results indicated that surveyed males tended to drink three times that of females, and depressive symptoms were associated with higher levels of alcohol use.

DISCUSSION

This study highlights the need to examine AI alcohol use with sex in mind.

Non-alcoholic fatty liver disease (NAFLD) as a neglected metabolic companion of psychiatric disorders: common pathways and future approaches

BACKGROUND

Non-alcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis in over 5% of the parenchyma in the absence of excessive alcohol consumption. It is more prevalent in patients with diverse mental disorders, being part of the comorbidity driving loss of life expectancy and quality of life, yet remains a neglected entity. NAFLD can progress to non-alcoholic steatohepatitis (NASH) and increases the risk for cirrhosis and hepatic carcinoma. Both NAFLD and mental disorders share pathophysiological pathways, and also present a complex, bidirectional relationship with the metabolic syndrome (MetS) and related cardiometabolic diseases.

MAIN TEXT

This review compares the demographic data on NAFLD and NASH among the global population and the psychiatric population, finding differences that suggest a higher incidence of this disease among the latter. It also analyzes the link between NAFLD and psychiatric disorders, looking into common pathophysiological pathways, such as metabolic, genetic, and lifestyle factors. Finally, possible treatments, tailored approaches, and future research directions are suggested.

CONCLUSION

NAFLD is part of a complex system of mental and non-communicable somatic disorders with a common pathogenesis, based on shared lifestyle and environmental risks, mediated by dysregulation of inflammation, oxidative stress pathways, and mitochondrial function. The recognition of the prevalent comorbidity between NAFLD and mental disorders is required to inform clinical practice and develop novel interventions to prevent and treat these complex and interacting disorders.

Cardiovascular Health among U.S. Indigenous Peoples: A Holistic and Sex-Specific Systematic Review

PURPOSE

The purpose of this systematic review is to examine mental, sociocultural, behavioral, and physical risk and protective factors related to cardiovascular disease (CVD) and related outcomes among U.S. Indigenous peoples.

METHODS

A total of 51 articles met the inclusion criteria of research focusing factors for CVD among U.S. Indigenous peoples (Mental n= 15; Sociocultural, n =17; Behavioral/Physical, n =19).

RESULTS

This review reveals clear risks for CVD, which tended to be elevated for females. Mental health problems (depression, anxiety, PTSD/trauma, alcohol and other drug (AOD) abuse) were clearly associated with CVD, along with enculturation, social support, and the social environment-including discrimination and trauma. Poor diet and obesity, diabetes, hypertension, cholesterol were behavioral or physical factors.

DISCUSSION

Overall, identified research was limited and in beginning stages, lacking more information on etiology of the interconnections across sex and the mental, sociocultural, and behavioral determinants of CVD.

The Relation Between Depressive Symptoms and Self-Care in Patients with Diabetes Mellitus Type 2 in Kosovo

Background:

The depression is a significant problem in patients with diabetes. This research is the first of it’s kind conducted in the Republic of Kosovo to determine the prevalence of depression diagnosed in people with diabetes mellitus type 2 (DMT2) and interrelation between depressive symptoms and behavior of diabetes self-care (glucose monitoring, exercise, diet, and self- health care).

Methods:

Research was conducted in the University Clinical Center of Kosovo (UCCK), in Pristine. The sample consisted of 200 individuals. Data collection was done through structured questionnaires. HANDS (Harvard Department of Psychiatry / National Depression Screening Day Scale) questionnaire was used to assess depressive symptoms and DSMQ (The Diabetes Self-Management Questionnaire) was used to assess self-care behavior. Data analysis was run through SSPS program, version 21.

Results:

The results showed that the prevalence of depression in diabetic patients was 66.5% in Kosovo. Being a woman, a resident of rural areas or with low level of education, there were significant predictors and were associated with increased chance of developing the symptoms of major depression. Significant relations were found between major depression and physical activity (p<0.05). While between major depression and management of blood glucose level, dietary control and self health care, no significant correlation was found.

Conclusion:

This paper concluded the involvement of psychological aspect in health care plan for diabetics, in order to reduce the number of individuals affected by depression, to diagnose and to treat these individuals for a better quality of life.

Association between low serum 25-hydroxyvitamin D and depression in a large sample of Chinese patients with type 2 diabetes mellitus

BACKGROUND

Because of the absence of data on the direct association between vitamin D and depression in patients with diabetes, we examined the association between vitamin D state (assessed by 25-hydroxyvitamin D [25(OH)D]) and the prevalence of depression in adult patients with type 2 diabetes mellitus(T2DM).

METHOD

Cross-sectional data were obtained from 2786 patients with T2DM recruited from a Chinese diabetes registry. Patients' records were reviewed to obtain data pertaining to age, sex, Body Mass Index (BMI), marital status, level of education, smoking status, duration of diabetes mellitus, use of insulin, and presence of additional illnesses. A multiple logistic regression analysis adjusted for potential confounders was used to assess independent associations between serum levels of 25 (OH)D and depression (defined by the Patient Health Questionnaire-9).

RESULTS

Using the PHQ-9 cutoff value of ≥10, 5.71% (159/2786; 95% CI: 4.85-6.57%) were considered to have depression. The serum 25(OH)D levels were significantly lower in diabetic patients with depression than those patients without depression [10.2(IQR, 7.6-15.2)ng/ml vs. 14.6(IQR, 10.7-19.8)ng/ml, respectively; P<0.0001]. Multivariate logistic regression analysis considering traditional risk factors and other biomarkers showed an inverse relationship between serum 25 (OH)D levels and depression when serum 25 (OH)D were used as a continuous variable (OR, 0.84; 95% CI, 0.77-0.90; P<0.001). Compared with the first quartile of serum 25 (OH)D levels, the second quartile OR for depression was 0.83 (95% CI, 0.75-0.92, P=0.012). For the third and fourth quartiles, it was 0.40 (95% CI, 0.33-0.52, P<0.001) and 0.15 (95% CI, 0.08-0.22; P<0.001), respectively.

CONCLUSIONS

We observed a significant negative association between serum levels of 25 (OH)D and depression in Chinese patients with T2DM.

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.

Rates and consequences of posttraumatic distress among American Indian adults with type 2 diabetes

This study examined the prevalence of screened posttraumatic stress disorder (PTSD) and associated diabetes-related outcomes. A sample of American Indian adults with type 2 diabetes (n = 218) participated in interviewer-administered surveys. Using a cutoff of 3 on the Primary Care PTSD screener, 21.8 % of participants screened positive for PTSD. PTSD symptoms were negatively associated with self-rated health status and positively associated with past year hospitalization after controlling for several demographic factors, but not after controlling for depressive symptoms. Past month frequency of hyperglycemia symptoms was not related to PTSD symptoms. When grouped by mental health conditions (neither screened PTSD nor depressive symptoms, screened PTSD only, depressive symptoms only, and both), those with both screened PTSD and depressive symptoms reported the highest proportion of any past month hyperglycemia, past year hospitalization, and low self-rated health status. Screened PTSD, especially in those with comorbid depressive symptoms, is an important consideration in diabetes care.

Psychiatric referral and glycemic control of Egyptian type 2 diabetes mellitus patients with depression

OBJECTIVE

To evaluate the relationship between psychiatric referral acceptance for fluoxetine treatment and glycemic control in type 2 diabetes mellitus (T2DM) Egyptian patients with depression.

METHODS

Patients with T2DM who attended the diabetes outpatients clinic at Zagazig University Hospital, Egypt, between May 2013 and April 2015 and who scored ≥20 on screening with the Major Depression Inventory (MDI) (n=196) were offered a psychiatric referral for fluoxetine treatment and monitoring. Decliners (56.1%) received time/attention matched care via diabetologist visits (attentional controls). Fluoxetine patients and controls were compared at the time of the offer (T1) and 8weeks later (T2). Factors that significantly correlated with glycemic control were used in a linear regression analysis as the independent variables.

RESULTS

Eighty-six patients (43.9%) accepted psychiatric referral. Most of them (97.7%) remained throughout the study adherent to fluoxetine (mean daily dose=31.9mg). At T2, these patients, in comparison to controls, showed a reduction from baseline in MDI, fasting plasma glucose and glycosylated hemoglobin (HbA1c) levels (P for all comparisons <.001). In the final model of a regression analysis, 65.9% of the variation in percentage change in HbA1c was explained by adherence to antidiabetics, psychiatric referral acceptance and Internalized Stigma of Mental Illness (ISMI) and MDI scores.

CONCLUSION

In T2DM patients with depression, psychiatric referral acceptance for fluoxetine treatment is a significant predictor of both depression and glycemic control improvements.

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.

The effect of problem solving and decision making skills on tendency to depression and anxiety in patients with type 2 diabetes

BACKGROUND

Diabetes is the most prevalent disease that has involved 177 million people all over the world and, due to this, these patients suffer from depression and anxiety and they should use special methods for controlling the same. The aim of this research is the study of the effect of problem solving and decision making skill on the rate of the tendency to depression and anxiety.

MATERIALS AND METHODS

This research is a quasi-experimental (case-control) study. Statistically, the population of the present study was all diabetic patients of Qaemshahr who were controlled by physicians in 2011-2012. Thirty files were selected randomly from them and divided into two 15 patients' groups (control and subject group) randomly. The measurement tools were Back depression inventory (21 items) and Zank anxiety questionnaire that were distributed among two groups. Then, the subject group participated in eight sessions of teaching problem solving and decision making courses separately, and the second group (control group) did not receive any instruction.

RESULTS

Finally, both groups had passed post-test and the data obtained from the questionnaires were studied by variance analysis statistical methods.

CONCLUSION

The results showed that teaching problem solving and decision making skills was very effective in reducing diabetic patients' depression and anxiety and resulted in reducing their depression and anxiety.

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.

Prevalence and influencing factors of co-morbid depression in patients with type 2 diabetes mellitus: a General Hospital based study

BACKGROUND

Depression and diabetes have been recognized as major public health issues in China, however, no studies to date examined the factors associated with the development of depression in patients with diabetes in China. This study aimed to estimate the prevalence of co-morbid depression among adults with type 2 diabetes mellitus (DM) and to examine the influence factors of co-morbid depression in a group of patients with type 2 DM.

METHODS

The study was conducted from March l to May 31, 2012, in the Department of Endocrinology of the First Affiliated Hospital of the General Hospital of the People's Liberation Army (PLA). A systematic random sample of 412 type 2 DM patients aged over 18 years was selected. A structured questionnaire was used for collecting the information about socio-demographic data, lifestyle factors and clinical characteristics. Depression and social support was evaluated by using the Chinese version of Beck Depression Inventory (BDI) and Social Support Rate Scale (SSRS), respectively. Weights and heights were measured. Hemoglobin A1c (HbA1c) was abstracted from each patient directly after the interview.

RESULTS

Of the total sample, 142 patients had depression according to the BDI scores (BDI scores ≥14), the prevalence of co-morbid depression in this study population was 5.7 % (142/2500). Of which, 56 had major depression (BDI ≥ 21), and 86 had moderate depression (BDI ≥ 14&BDI < 21). Logistic regression analysis indicated that a high HbA1c level, a high BMI, low quality health insurance, and being single, were significantly associated with the development of depression. However, a family history of diabetes and a high social support level are likely protective factors.

CONCLUSIONS

The prevalence of co-morbid depression was 5.7 % among Chinese subjects with type 2 DM in this study. High HbA1c level, high BMI score, being single, low social support level, and low quality health insurance were associated with the presence of depression. These findings support a recommendation for routine screening and management in China for depression in patients with diabetes, especially for those in primary care, to reduce the number of the depressed or the misrecognized depressed diabetic patients.

Association of depression with type 2 diabetes and relevant factors

BACKGROUND

Based on the high prevalence of diabetes and depression in Rasht, we conducted a study to evaluate the prevalence of depression in type 2 diabetic patients, and its association with glycemic control, chronic complications, and some clinical and paraclinical parameters in this northern state of Iran.

MATERIALS AND METHODS

Beck depression inventory was used for evaluating depression on 90 type 2 diabetics and 90 healthy controls selected. Information on demographic and clinical and paraclinical characteristics was collected by interviews and from medical records.

RESULTS

This cross-sectional study was performed on 90 type 2 diabetic patients (63 female and 27 male with a mean age of 54.17 ± 10.57 years) and 90 healthy matched controls. Overall, depression was significantly more prevalent in case group [37.8% vs. 16%, odds ratio (OR) = 3.29, P = 0.001]. The prevalence of depression in diabetic women was significantly higher than nondiabetic ones (39.7% vs. 15%, P = 0.002). We could not find any significant correlation between depression and positive family history of depression, duration of diabetes, HBA1c level, and body mass index. The prevalence of depression was prominently more in diabetic patients with retinopathy than in those without this complication (55.6% vs. 24%, P = 0.015). Logistic regression analysis indicated that diabetes itself was the only significant determinant of having depression (OR = 3.29, P = 0.005, 95% confidence interval: 0.118-0.667).

CONCLUSION

There was a prominent prevalence of depression in type 2 diabetics overall. Depression was not correlated with duration of diabetes and glycemic control. There was a significant association between depression and retinopathy in diabetic patients. Diabetes itself was the only significant determinant of having depression after matching with other variables.

The Prevalence and Correlates of Mental and Emotional Health Among American Indian Adults With Type 2 Diabetes

AIMS

The purpose of this study was to examine the prevalence and correlates of mental and emotional health factors among a sample of American Indian (Indigenous) adults diagnosed with type 2 diabetes.

METHODS

Data are from a community-based participatory research project involving 2 Indigenous reservation communities. Data were collected from 218 Indigenous adults diagnosed with type 2 diabetes via in-person paper-and-pencil survey interviews.

RESULTS

Reports of greater numbers of mental/emotional health problems were associated with increases in self-reported hyperglycemia, comorbid health problems, and health-impaired physical activities.

CONCLUSIONS

This study addresses a gap in the literature by demonstrating the associations between various mental/emotional health factors and diabetes-related health problems for Indigenous Americans. Findings underscore the importance of holistic, integrated primary care models for more effective diabetes care.

Prevalence of depression among people with type 2 diabetes mellitus: a cross sectional study in Palestine

BACKGROUND

Diabetes mellitus is a common chronic metabolic disorder and one of the main causes of death in Palestine. Palestinians are continuously living under stressful economic and military conditions which make them psychologically vulnerable. The purpose of this study was to investigate the prevalence of depression among type II diabetic patients and to examine the relationship between depression and socio-demographic factors, clinical factors, and glycemic control.

METHODS

This was a cross-sectional study at Al-Makhfiah primary healthcare center, Nablus, Palestine. Two hundred and ninety-four patients were surveyed for the presence of depressive symptoms using Beck Depression Inventory (BDI-II) scale. Patients' records were reviewed to obtain data pertaining to age, sex, marital status, Body Mass Index (BMI), level of education, smoking status, duration of diabetes mellitus, glycemic control using HbA1C test, use of insulin, and presence of additional illnesses. Patients' medication adherence was assessed using the 8-item Morisky Medication Adherence Scale (MMAS-8).

RESULTS

One hundred and sixty four patients (55.8%) of the total sample were females and 216 (73.5%) were < 65 years old. One hundred and twenty patients (40.2%) scored ≥ 16 on BDI-II scale. Statistical significant association was found between high BDI-II score (≥ 16) and female gender, low educational level, having no current job, having multiple additional illnesses, low medication adherence and obesity (BMI ≥ 30 kg/m2). No significant association between BDI score and glycemic control, duration of diabetes, and other socio-demographic factors was found. Multivatriate analysis showed that low educational level, having no current job, having multiple additional illnesses and low medication adherence were significantly associated with high BDI-II scores.

CONCLUSION

Prevalence of depression found in our study was higher than that reported in other countries. Although 40% of the screened patients were potential cases of depression, none were being treated with anti-depressants. Psychosocial assessment should be part of routine clinical evaluation of these patients at primary healthcare clinics to improve quality of life and decrease adverse outcomes among diabetic patients.

Prevalence of depression and associated risk factors among persons with type-2 diabetes mellitus without a prior psychiatric history: a cross-sectional study in clinical settings in urban Nepal

BACKGROUND

Diabetes is a growing health problem in South Asia. Despite an increasing number of studies exploring causal pathways between diabetes and depression in high-income countries (HIC), the pathway between the two disorders has received limited attention in low and middle-income countries (LMIC). The aim of this study is to investigate the potential pathway of diabetes contributing to depression, to assess the prevalence of depression, and to evaluate the association of depression severity with diabetes severity. This study uses a clinical sample of persons living with diabetes sequelae without a prior psychiatric history in urban Nepal.

METHODS

A cross-sectional study was conducted among 385 persons living with type-2 diabetes attending tertiary centers in Kathmandu, Nepal. Patients with at least three months of diagnosed diabetes and no prior depression diagnosis or family history of depression were recruited randomly using serial selection from outpatient medicine and endocrine departments. Blood pressure, anthropometrics (height, weight, waist and hip circumference) and glycated hemoglobin (HbA1c) were measured at the time of interview. Depression was measured using the validated Nepali version of the Beck Depression Inventory (BDI-Ia).

RESULTS

The proportion of respondents with depression was 40.3%. Using multivariable analyses, a 1-unit (%) increase in HbA1c was associated with a 2-point increase in BDI score. Erectile dysfunction was associated with a 5-point increase in BDI-Ia. A 10 mmHg increase in blood pressure (both systolic and diastolic) was associated with a 1.4-point increase in BDI-Ia. Other associated variables included waist-hip-ratio (9-point BDI-Ia increase), at least one diabetic complication (1-point BDI-Ia increase), treatment non-adherence (1-point BDI-Ia increase), insulin use (2-point BDI-Ia increase), living in a nuclear family (2-point BDI-Ia increase), and lack of family history of diabetes (1-point BDI-Ia increase). Higher monthly income was associated with increased depression severity (3-point BDI-Ia increase per 100,000 rupees, equivalent US$1000).

CONCLUSIONS

Depression is associated with indicators of more severe diabetes disease status in Nepal. The association of depression with diabetes severity and sequelae provide initial support for a causal pathway from diabetes to depression. Integration of mental health services in primary care will be important to combat development of depression among persons living with diabetes.

Health and psychosocial outcomes in U.S. adult patients with diabetes from diverse ethnicities

Within the United States, diabetes is a serious public health concern and patients with diabetes are more likely to experience clinical depression, psychological distress, and depressive symptoms than those without. Negative psychosocial factors are associated with poorer diabetes management and glycemic control. Overall, both the rates of diabetes and related psychological distress are greater for persons of diverse ethnicities than for non-Latino whites, and have reached epidemic proportions in certain groups. The following article will provide an overview across ethnicities of the rates of diabetes, health outcomes, psychosocial outcomes, and unique cultural and linguistic challenges that contribute to disparities within US diabetes patients of diverse ethnicities. Using this information, our hope is that health care practitioners and researchers alike can better respond to the psychosocial needs of ethnically diverse patients.

Epidemiology of depression in diabetes: international and cross-cultural issues

INTRODUCTION

This paper reviews the most up-to-date epidemiological evidence of the relationship between depression and diabetes, and considers the risk factors for the development of depression and the consequences of depression in diabetes with an emphasis on international and cross-cultural data. The difficulties that researchers face when epidemiological studies require assessment of psychological phenomena, such as depression, across different cultural settings are explored.

METHODS

Relevant papers were sought on the epidemiology of diabetes and depression in people with diabetes by undertaking a literature search of electronic databases including MEDLINE, Psych-INFO, CINAHL and EMBASE. These papers were assessed by the authors and a narrative review of the relevant literature was composed.

RESULTS

Systematic reviews of the prevalence of depression in people with diabetes have focused on studies conducted in English speaking countries and emerging data suggest that there may be international variations in prevalence and also in how symptoms of depression are reported. There appears to be a bi-directional relationship between depression and diabetes, with one influencing the other; however, research in this area is further complicated by the fact that potential risk factors for depression in people with diabetes often interact with each other and with other factors. Further research is needed to elucidate the causal mechanisms underlying these associations.

LIMITATIONS

Data from non-English speaking countries remain scarce and so it is difficult to come to any firm conclusions as to the international variation in prevalence rates of co-morbid diabetes and depression in these countries until further research has been conducted.

CONCLUSION

It is important to take a culture-centered approach to our understanding of mental health and illness and consider the key issues related to the development of culturally sensitive depression screening tools. In order to come to any firm conclusions about the international variation in prevalence of co-morbid diabetes and depression, issues of culture and diversity must be taken into account prior to conducting international epidemiological studies.

Correlation of magnesium intake with metabolic parameters, depression and physical activity in elderly type 2 diabetes patients: a cross-sectional study

BACKGROUND

Type 2 diabetes mellitus is a major global public health problem in the worldwide and is increasing in aging populations. Magnesium intake may be one of the most important factors for diabetes prevention and management. Low magnesium intake may exacerbate metabolic abnormalities. In this study, the relationships of magnesium intake with metabolic parameters, depression and physical activity in elderly patients with type 2 diabetes were investigated.

METHODS

This cross-sectional study involved 210 type 2 diabetes patients aged 65 years and above. Participants were interviewed to obtain information on lifestyle and 24-hour dietary recall. Assessment of depression was based on DSM-IV criteria. Clinical variables measured included anthropometric measurements, blood pressure, and biochemical determinations of blood and urine samples. Linear regression was applied to determine the relationships of magnesium intake with nutritional variables and metabolic parameters.

RESULTS

Among all patients, 88.6% had magnesium intake which was less than the dietary reference intake, and 37.1% had hypomagnesaemia. Metabolic syndromes and depression were associated with lower magnesium intake (p < 0.05). A positive relationship was found between magnesium intake and HDL-cholesterol (p = 0.005). Magnesium intake was inversely correlated with triglyceride, waist circumference, body fat percent and body mass index (p < 0.005). After controlling confounding factor, HDL-cholesterol was significantly higher with increasing quartile of magnesium intake (p for trend = 0005). Waist circumference, body fat percentage, and body mass index were significantly lower with increase quartile of magnesium intake (p for trend < 0.001). The odds of depression, central obesity, high body fat percentage, and high body mass index were significantly lower with increasing quartile of magnesium intake (p for trend < 0.05). In addition, magnesium intake was related to high physical activity level and demonstrated lower serum magnesium levels. Serum magnesium was not significantly associated with metabolic parameters.

CONCLUSIONS

The majority of elderly type 2 diabetes who have low magnesium intake may compound this deficiency with metabolic abnormalities and depression. Future studies should determine the effects of increased magnesium intake or magnesium supplementation on metabolic control and depression in elderly people with type 2 diabetes.

Depression prevalence and associated factors among Alaska Native people: the Alaska education and research toward health (EARTH) study

BACKGROUND

Few studies have investigated depression among Alaska Native people (ANs). Depression prevalence and associated factors among EARTH Alaska study participants are described.

METHODS

The nine-item Patient Health Questionnaire (PHQ-9) assessed depression among 3771 ANs. Participants with PHQ-9 scores≥10 out of 27 were classified as positive for depression. Logistic regression analyses evaluated odds of scoring positive versus negative for depression by demographic, cultural, then health and lifestyle factors.

RESULTS

Twenty percent of women and 13% of men scored positive for depression. Univariate and multivariate models were fit separately for men and women. Among demographic factors, below median income was associated with positive depression scores for both genders. Among men, odds of depression were higher if unmarried and/or if highest educational level was less than high school. Women 34 to 59 years of age had increased odds of scoring positive. Little or no identification with tribal tradition was associated with increased odds of depression in women and decreased odds in men. For both genders, chronic physical conditions and poorer self-reported health were associated with positive depression scores then binge alcohol drinking and current tobacco use increased odds of depression among women only.

LIMITATIONS

Factors analyzed were self-reported without clinician follow-up in a non-random convenience sample of adults.

CONCLUSIONS

Depression is common among ANs with rates comparable to other indigenous cross-sectional investigations. Depression is associated with lower income and poorer physical health. Prevention and intervention efforts should consider gender as other associated factors varied between men and women.

[Clinical aspects of the link between diabetes and depression]

Diabetes mellitus and depression are public health concerns of the present and, as predicted, also the future. The observation that depression is seen more frequently in diabetic patients compared to the non-diabetic population has been proven by several recent studies. The co-occurrence carries further risks for the affected patients, as depression in diabetics may affect sufficient treatment of diabetes and enhance the development of diabetic complications. These may further worsen depressive symptoms causing a vicious cycle in these patients. In the present paper authors discuss in detail the theoretic and practical issues of the complex two directional relationships between diabetes and depression. Their goal is to draw attention to depression as co-morbidity of diabetes that may interfere with the optimization of diabetic patient's carbohydrate metabolism. If sufficient glycaemic control is not achieved using routine clinical methods depression should be evaluated as a probable cause. If needed, depression should be treated to improve the medical outcomes and quality of life of diabetic patients.

Association of depression with treatment outcomes in Type 2 Diabetes Mellitus: a cross-sectional study from Karachi, Pakistan

BACKGROUND

To assess the associations of depression with glycemic control and compliance to self-care activities in adult patients with Type 2 Diabetes Mellitus

METHODS

This cross-sectional study was conducted at a tertiary-care hospital in Karachi (Aga Khan University Hospital). Equal numbers of depressed and non-depressed patients were consecutively recruited from the diabetic clinic. Information on demographic and clinical characteristics was collected in face-to-face interviews and from medical records. Hospital Anxiety Depression Scale (HADS) was used to measure depression. Associations of depressed status (HADS ≥ 8) with poor glycemic control (Hemoglobin A1c level ≥ 7%) and compliance to self-care activities were assessed by logistic regression analyses.

RESULTS

A total of 286 patients were included in this study with a male-female ratio of 1.2:1. Mean age was 52 years and in 64.7% of them, the duration of diabetes was more than 3 years. Depressed patients were more likely to be female (adjusted odds ratio [OR] = 1.88; 95% confidence interval [95%CI] = 1.07-3.31), had a family history of diabetes (OR = 2.64; 95%CI = 1.26-5.55), and poor glycemic control (OR = 5.57; 95%CI = 2.88-10.76) compared with non-depressed patients. Depression was also associated with low compliance to self-care activities such as taking dose as advised (OR = 0.32; 95%CI = 0.14-0.73), dietary restrictions (OR = 0.45; 95%CI = 0.26-0.79) and foot care (OR = 0.38; 95%CI = 0.18-0.83).

CONCLUSIONS

Adult patients with Type 2 Diabetes who have depression were more likely to have poor glycemic control and lower compliance to self-care activities, and they might need particular attention during follow-up visits.

Staying Connected: A Feasibility Study Linking American Indian and Alaska Native Trauma Survivors to their Tribal Communities

The objective of this investigation was to assess the feasibility of a culturally tailored care management intervention for physically injured American Indian/Alaska Native (AI/AN) patients. The intervention was initiated at a Level I trauma center and aimed to link AI/AN patients to their distant tribal communities. Thirty AI/AN patients were randomized to the intervention or to usual care. Assessments at baseline, 3 months, and 6 months included self-reported lifetime cumulative trauma burden, Native healing requests, and symptoms of posttraumatic stress, depression, and alcohol use. Generalized estimating equations ascertained differences between groups over time. Ninety-four percent of eligible patients participated; follow-up at 3 and 6 months was 83%. Participants had high numbers of lifetime traumas (mean = 5.1, standard deviation = 2.6). No differences between the intervention and control groups were observed in posttraumatic stress symptoms, depression symptoms, or alcohol use at baseline or follow-up time points. Among intervention patients, 60% either requested or participated in traditional Native healing practices and 75% reported that the intervention was helpful. This effectiveness trial demonstrated the feasibility of recruiting and randomizing injured AI/AN patients. Future efforts could integrate evidence-based interventions and traditional Native healing into stepped collaborative care treatment programs.

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

OBJECTIVES

To examine the relationship between depression and glycemic control in the Strong Heart Study (SHS), a longitudinal study of cardiovascular disease in American Indians.

METHODS

This cross-sectional analysis focused on the relationship between depression, diabetes and glycemic control among 2832 individuals aged > or =15 years. Depression was measured by the Center for Epidemiologic Studies of Depression Scale and diabetes by American Diabetes Association criteria. An ordered logit regression model was used to assess whether diabetes was related to level of depression (none, mild, moderate, severe). Multiple logistic regression was used to explore the relationship between A1c and severe depression in participants with diabetes.

RESULTS

Rates of depression were higher in men and women with diabetes when compared to those without diabetes, respectively (P<.05). For every 1-U increase in A1c, the odds of severe depression increased by 22% (OR 1.22, 95% CI: 1.05-1.42). Female sex (OR 2.97, 95% CI: 1.32-6.69) and body mass index (BMI) (OR 1.04, 95% CI: 1.00-1.08) also were significantly associated with increased risk for severe depression. Although BMI appears to be significantly associated with increased risk for severe depression, the magnitude of this effect was small.

CONCLUSIONS

Individuals with diabetes have higher rates of depression than those without diabetes, consistent with other populations. There is a positive relationship between severity of depression and A1c levels; men and women with severe depression have higher A1c levels than those with moderate-to-no depression.

The role of public health in addressing racial and ethnic disparities in mental health and mental illness

Racial/ethnic minority populations are underserved in the American mental health care system. Disparity in treatment between whites and African Americans has increased substantially since the 1990s. Racial/ethnic minorities may be disproportionately affected by limited English proficiency, remote geographic settings, stigma, fragmented services, cost, comorbidity of mental illness and chronic diseases, cultural understanding of health care services, and incarceration. We present a model that illustrates how social determinants of health, interventions, and outcomes interact to affect mental health and mental illness. Public health approaches to these concerns include preventive strategies and federal agency collaborations that optimize the resilience of racial/ethnic minorities. We recommend strategies such as enhanced surveillance, research, evidence-based practice, and public policies that set standards for tracking and reducing disparities.

Cardiovascular disease and diabetes in people with severe mental illness position statement from the European Psychiatric Association (EPA), supported by the European Association for the Study of Diabetes (EASD) and the European Society of Cardiology (ESC)

People with severe mental illnesses, such as schizophrenia, depression or bipolar disorder, have worse physical health and reduced life expectancy compared to the general population. The excess cardiovascular mortality associated with schizophrenia and bipolar disorder is attributed in part to an increased risk of the modifiable coronary heart disease risk factors; obesity, smoking, diabetes, hypertension and dyslipidaemia. Antipsychotic medication and possibly other psychotropic medication like antidepressants can induce weight gain or worsen other metabolic cardiovascular risk factors. Patients may have limited access to general healthcare with less opportunity for cardiovascular risk screening and prevention than would be expected in a non-psychiatric population. The European Psychiatric Association (EPA), supported by the European Association for the Study of Diabetes (EASD) and the European Society of Cardiology (ESC) published this statement with the aim of improving the care of patients suffering from severe mental illness. The intention is to initiate cooperation and shared care between the different healthcare professionals and to increase the awareness of psychiatrists and primary care physicians caring for patients with severe mental illness to screen and treat cardiovascular risk factors and diabetes.
