Depression in diabetics: a critical appraisal

The risk of experiencing depression among older adults in India: A cross-sectional study

Background

The comorbidity of diabetes and depression poses a major challenge to older adults. While a few small scale studies have investigated the diabetes associated risk of experiencing depression, there is no national-level study available for India on the same. In this context, this study estimates the burden and risk of depression due to diabetes among older adults aged 45 and above in India while adjusting for socio-economic and demographic characteristics of the individuals.

Methods

Longitudinal Ageing Study in India (LASI), 2017-2018 wave 1 data was utilised in this study. The prevalence of depression and diabetes were estimated by background characteristics using bivariate cross-tabulation. In addition, multivariate logistic regression was applied to examine the likelihood of depression associated with diabetes and other covariates.

Result

Empirical estimation demonstrated that 14% of males and 8% of females with diabetes suffer from depression in the 45-59 age group. A diabetic person aged 45 and above was 16% more likely to suffer from depression than a non-diabetic person; whereas, a diabetic elderly aged 60 and above was 24% more likely to experience depression than their non-diabetic counterparts. The multivariate analysis confirmed a highly statistically significant association between diabetes and depression indicating a substantial risk to experience depression among those older adults and elderly who suffer from diabetes.

Conclusion

Elderly population (60 +) is at higher risk of experiencing depression due to diabetes. Therefore, public health care awareness should be raised, particularly among endocrinologists or specialist doctors who provide treatment at the tertiary-care hospitals in India. The health care experts should refer/recommend the diabetic patients to screen for depressive symptoms.

Six-month and lifetime prevalences of psychiatric disorders in inpatients with diabetes mellitus

The Composite International Diagnostic Interview (CIDI) was used to assess the prevalence of psychiatric disorders in a French population of 46 inpatients with diabetes mellitus. According to DSM-III-R criteria, 52.2% of subjects presented at least one psychiatric diagnosis in their lifetime and 41.3% did so less than six months before the study. Affective and anxiety disorders represented at least 83% of the psychiatric diagnoses. The risk for those disorders seems to be restricted to a predisposed group as only one of the 16 subjects who had suffered from an anxiety or depressive episode within the previous six months had never experienced such an episode before.

Vanadium-Enriched Cordyceps sinensis, a Contemporary Treatment Approach to Both Diabetes and Depression in Rats

This article studies a contemporary treatment approach toward both diabetes and depression management by vanadium-enriched Cordyceps sinensis (VECS). Streptozotocin-induced hyperglycemic rats were used in the study. After the rats were administered with VECS, a significant reduction in blood glucose levels was seen (P < .05) and the levels of serum insulin increased significantly (P < .05). At the same time, the study revealed a significant decrease in immobility with a corresponding increase in the swimming and climbing behavior in hyperglycemic rats following VECS treatment. The results described herein demonstrate that VECS is a contemporary treatment approach that advocates an aggressive stance toward both diabetes and depression management.

A Contemporary Treatment Approach to Both Diabetes and Depression by Cordyceps sinensis, Rich in Vanadium

Diabetes mellitus is accompanied by hormonal and neurochemical changes that can be associated with anxiety and depression. Both diabetes and depression negatively interact, in that depression leads to poor metabolic control and hyperglycemia exacerbates depression. We hypothesize one novel vanadium complex of vanadium-enriched Cordyceps sinensis (VECS), which is beneficial in preventing depression in diabetes, and influences the long-term course of glycemic control. Vanadium compounds have the ability to imitate the action of insulin, and this mimicry may have further favorable effects on the level of treatment satisfaction and mood. C. sinensis has an antidepressant-like activity, and attenuates the diabetes-induced increase in blood glucose concentrations. We suggest that the VECS may be a potential strategy for contemporary treatment of depression and diabetes through the co-effect of C. sinensis and vanadium. The validity of the hypothesis can most simply be tested by examining blood glucose levels, and swimming and climbing behavior in streptozotocin-induced hyperglycemic rats.

Depressive und Angststörungen bei somatischen Krankheiten

Depressiv-ängstliche Störungen sind bei den unterschiedlichen somatischen Erkrankungen häufig. Sie sind nicht nur als Reaktion auf die Situation der Erkrankung zu verstehen, sondern in ein komplexes Bedingungsgefüge eingebettet. Sie sind besonders häufig bei Erkrankungen, die das Zentralnervensystem oder endokrine Regulationssysteme direkt betreffen. Es besteht ein enger Zusammenhang zur Chronizität, Schwere und Prognose der Erkrankung. Eigenständige Effekte von diversen pharmakologischen Substanzgruppen sind wahrscheinlich.

Type 1 Diabetes

Type 1 diabetes is a tremendously challenging and complex disease for children and families to manage. Advances in research are constantly bringing about changes in therapies and treatments with the hope of improving the quality of life for youth with type 1 diabetes and their families. Accurate diagnosis, education, treatment, and referral to a certified diabetes educator, endocrinologist, dietitian, social worker, and psychologist are needed to provide the child with the skills necessary to manage diabetes over a lifetime. Nurses and nurse practitioners must be informed of the most current treatments and research available for their patients so that they can encourage their patients to live full and healthy lives.

Disease-focused or integrated treatment: diabetes and depression

This article reviewed the literature on the adverse health outcomes of the coexistence of diabetes and depression, the challenges of treating coexisting diabetes and depression in a fragmented health care system, and the need for integrated care as a strategy to improve the quality of care for patients who have complex medical illnesses (eg, patients who have coexisting diabetes and depression).

Is depression related to subsequent diabetes mellitus?

OBJECTIVE

To compare the risk of developing diabetes mellitus (DM) in the general population between subjects who had a depression and subjects who never had a depression.

METHOD

Retrospective cohort design. People with depression were diagnosed with a depression between 1975 and 1990; controls never had a depression. Both groups were followed for a diagnosis of type II diabetes until 2000. Data on 1334 depressed and 66 670 non-depressed subjects were available from a large general practice-based database.

RESULTS

No overall relation was found, but among males below age 50 there was a 78% increase in the rate of development of DM compared with non-depressed patients (hazard ratio 1.78, 95% CI: 1.21-2.62).

CONCLUSION

Depression in males between the age of 20 and 50 years is related to an increased risk of developing DM.

Relationship of depression to diabetes types 1 and 2: epidemiology, biology, and treatment

This article reviews the rapidly accumulating literature on the relationship between mood disorders and diabetes mellitus. Recent studies have demonstrated that depression and its associated symptoms constitute a major risk factor in the development of type 2 diabetes and may accelerate the onset of diabetes complications. Since the mid-1980s, multiple longitudinal and cross-sectional studies have scrutinized the association of diabetes with depressive symptoms and major depression. Utilizing the search terms depressive disorders, psychiatry, diabetes, and pathophysiology in MEDLINE searches (1966-2003), this article reviews studies investigating pathophysiological alterations related to glucose intolerance and diabetes in depressed patients. The few randomized, controlled studies of treatment of depression in patients with diabetes are also described. Short-term treatment of depression in patients with diabetes improves their dysphoria and other signs and symptoms of depression. Future research will confirm whether response to psychotherapy and/or psychopharmacologic treatment improves glucose control, encourages compliance with diabetes treatment, and perhaps even increases longevity.

Depression and chronic diabetic foot disability. A case report of suicide

Evidence at the scene of death and the postmortem examination led the pathologist to conclude suicide by intentional insulin overdose. The examination was conducted one day after the patient's death. The amount of insulin injected is not known, but levels of insulin in the vitreous gel were extremely high. While glucose and insulin are more stable in vitreous than in postmortem blood, the longer the delay between death and sample collection, the greater the uncertainty of the exact concentrations of substances at the time of death [42]. Patients with diabetes may have at their disposal the resources to end their lives; misuse of insulin and suicide by insulin overdose are presumably underreported events. Not only do diabetics have insulin available, but they may also have narcotics, tricyclic antidepressants or other drugs that are toxic at high doses. Even in the absence of depression, all patients with diabetes face multiple emotional issues related to the diagnosis and course of the disease. Diabetes often requires significant lifestyle changes, such as diet and physical activity, upon its diagnosis. Patients face the possibility of long-term, possibly debilitating, complications: vision loss, sexual dysfunction, and amputation. Any podiatrist who treats a large number of diabetic patients will encounter the situation of a patient at risk of losing a limb. A patient may consciously or unconsciously view amputation as punishment; limb loss interferes physically with bodily function and has extensive emotional consequences as well. It is important for patients to be involved with a healthcare team (including primary care physician, nurse educator, ophthalmologist, and podiatrist) that provides support throughout their lives [3]. As learned early on in podiatry school, podiatric physicians don't treat feet; they treat patients who have foot problems. It is as important to know when to refer a patient to the primary care physician or a psychiatrist for mental health complaints as it is to know when to refer a patient to an orthopedic surgeon for hip pain or to an ophthalmologist for vision problems. We do not propose that this patient's diabetic foot disease was the direct cause of his depression and suicide; however, the prevalence of depression in the general population and its even higher rates in patients with chronic medical illness require awareness of these problems by all members of the medical profession.

Treatment of depression in diabetes: impact on mood and medical outcome

Depression is prevalent as a co-morbid condition in diabetes. The efficacy of depression treatment with either pharmacological agents or psychotherapy has been demonstrated in the few available controlled trials. Depression has been associated with poor glycemic control and with accelerated rates of coronary heart disease in diabetic patients. Reported depression treatment trials demonstrate benefits of depression remission on glycemic control as well as mood and the potential for improvement in the course and outcome of diabetes. Because adverse effects of pharmacological agents on glycemic control have been observed, optimal therapies that improve both depression and measures of diabetes are still being sought. This review critically examines the efficacy of depression treatment in diabetes patients, the effects of depression treatment on the medical condition, and methodological issues important in the performance of treatment trials in the patient population.

Acute effect of different antidepressants on glycemia in diabetic and non-diabetic rats

Diabetic patients have a 20% higher risk of depression than the general population. Treatment with antidepressant drugs can directly interfere with blood glucose levels or may interact with hypoglycemic agents. The treatment of depression in diabetic patients must take into account variations of glycemic levels at different times and a comparison of the available antidepressant agents is important. In the present study we evaluated the interference of antidepressants with blood glucose levels of diabetic and non-diabetic rats. In a first experiment, male adult Wistar rats were fasted for 12 h. Imipramine (5 mg/kg), moclobemide (30 mg/kg), clonazepam (0.25 mg/kg), fluoxetine (20 mg/kg) sertraline (30 mg/kg) or vehicle was administered. After 30 min, fasting glycemia was measured. An oral glucose overload of 1 ml of a 50% glucose solution was given to rats and blood glucose was determined after 30, 60 and 90 min. Imipramine and clonazepam did not change fasting or overload glycemia. Fluoxetine and moclobemide increased blood glucose at different times after the glucose overload. Sertraline neutralized the increase of glycemia induced by oral glucose overload. In the second experiment, non-diabetic and streptozotocin-induced diabetic rats were fasted, and the same procedures were followed for estimation of glucose tolerance 30 min after glucose overload. Again, sertraline neutralized the increase in glycemia after glucose overload both in diabetic and non-diabetic rats. These data raise the question of whether sertraline is the best choice for prolonged use for diabetic individuals, because of its antihyperglycemic effects. Clonazepam would be useful in cases with potential risk of hypoglycemia.

Ethopharmacology of the antidepressant effect of clonazepam in diabetic rats

Diabetes-associated depression may occur due to changes in the quality of life imposed by treatment, or may be a consequence of the biochemical changes accompanying the disease. It was our objective to evaluate the behaviors of diabetic rats through an animal model of depression, and determine if a positive GABA modulator agent, clonazepam, is an effective antidepressant. Wistar male rats were submitted to the forced-swimming test after 26 days of the induction of diabetes with streptozotocin (60 mg/kg). Test and retest days analyzed with an ethological approach. Clonazepam (control, 0.25, 0. 5, and 1.0 mg/kg) was administered IP 24, 5, and 1 h before the retest. Diabetic rats presented longer immobility duration during test and retest of forced swimming. Diabetic rats dived significantly less during the test. Clonazepam 0.25 and 0.5 mg/kg decreased immobility of diabetic rats with no consequences on the behaviors of nondiabetic rats. These results demonstrate that diabetic rats present more intense depressive-like behavior, such as immobility and lack of interest in exploring the environment, when exposed to the forced-swimming test. It is possible that decreased GABA function is involved in depression associated with diabetes, because a benzodiazepine partially counteracts these changes without modifying blood glucose and glycogen parameters.

Relationship between depressive symptoms and diabetes among native Hawaiians

Increased prevalence of depression has been reported among diabetes patients. We examined this association between diabetes and depressive symptoms in a population-based study where glucose tolerance status was determined with World Health Organization (WHO) criteria. Fasting plasma glucose (FPG) was determined from blood collected from 574 native Hawaiians. The Centers for Epidemiological Studies-Depression (CES-D) scale was used to assess depressive symptoms in association with diabetes history and hemoglobin A1c (HbA1c). A significant association was observed between depressive symptoms and HBA1c that persisted after adjusting for age, BMI, gender, education, and after exclusion of participants reporting a history of diabetes. Diabetes history was no longer associated with CES-D depressive symptoms after adjusting for HbA1c. These results support the hypothesis that depressive symptoms associated with diabetes may be partially explained by a shared neuroendocrinological disturbance.

[Insulin-dependent diabetes mellitus in children and in adolescents: value of pedopsychiatric follow-up]

To assess the type of mental disorders met in the medical follow-up of insulin-dependent diabetic children (IDDM) and adolescents and their relationships with metabolic control (HbA1C) in young IDDM patients who consult in a department of child psychiatry.

POPULATION AND METHODS

Twenty boys and 37 girls (mean age: 14.7 +/- 4.1 years and mean duration of IDDM: 5.6 +/- 4.3 years were followed during 1 year by the same child psychiatrist (mean duration of follow-up: 22 months). They were assessed with several clinical interviews (mean: three by subject); mental disorders were classified according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, third edition revised (DSM III-R).

RESULTS

The study showed the importance of emotional disorders, 30 patients presenting at least an anxiety disorder and 17 an affective disorder, 11 a major depressive disorder and eight a dysthymic disorder. The most frequent anxiety disorders were phobias and overanxious disorders. Two patients had an anorexia nervosa, one a bulimia nervosa and nine an eating disorder not otherwise specified. There were ten diagnoses of disruptive behaviour disorders, one toxic substance abuse and 11 adaptation disorders. Seven subjects had a reading and writing learning disorder, three a coordination disorder and three a borderline IQ. Familial factors seemed very important. Nine patients had a parent-child problem, four sibling rivalry disorder and two an attachment disorder. Family problems (conflicts, separations, economical difficulties...) were found in 63% of cases. The mother or the father had mental disorders in 24 cases (42%). The diabetic patients with mental disorders had poor metabolic control (HbA1C = 9.9 +/- 2.4%) and ten subjects (18%) had already somatic complications. Some mental disorders were significantly associated with high HbA1C. The poorer metabolic controls were observed for eating disorders. Somatic complications were associated only with IDDM duration.

CONCLUSIONS

This study shows the presence of typical DSM III-R mental disorders in IDDM children and adolescents, principally emotional disorders, and their association with a higher somatic risk, maximum for eating disorders. It shows the interest of collaboration between diabetologist and child psychiatrist. The exact prevalence of these disorders should be assessed by epidemiological studies.

Diabetes Mellitus: Experiencing a Chronic Illness

Diabetes is a chronic, complex disease involving numerous pathophysiological features. There is a paucity of studies relating to psychological factors. The available research is not conclusive and in addition is largely quantitative in nature. The aim of this investigation was to gain an understanding of the life-world of people with diabetes and to acquire insight into the demanding aspects of their lives. The research procedure involved interviewing subjects who suffer from diabetes. A pilot study was conducted in order to test a number of open-ended questions. On the basis of these results, a set of semi-structured questions was formulated for the main study. The main study involved interviews with 13 subjects aged between 20 and 45 years who belonged to a diabetic organization and who volunteered for the investigation. The interviews were recorded on audiotape and later transcribed. Five of the protocols obtained were analyzed according to the method outlined by Giorgi and they produced an encompassing description of the life-world of a diabetic. The themes which emerged included the appearance of the first symptoms and their effect on people with diabetes, the impact of the diagnosis, the emerging pattern of the life-world of people with diabetes and the prospects for the future. The phenomenological approach proved valuable in highlighting many aspects of diabetes. Recommendations are made which may be of benefit to people with diabetes and their families.

Hormonal and blood glucose responsiveness as an indicator of specific emotional arousal in type 1 diabetics

The aim of the present study was to examine, whether individual emotional arousal induced by a specific stress interview may effect growth hormone (GH), cortisol, catecholamine and blood glucose levels in diabetes patients. To test the validity of this hypothesis we subjected 18 Type 1 diabetics and 18 healthy controls to a life event interview which produces individual arousal. During this stress interview catecholamines and plasma cortisol levels showed no significant increase, whereas there was a significant increase of GH over time in both group (p < 0.04), with a trend in diabetics to have a more marked GH response than controls (p < 0.10). Blood glucose levels remained unaffected by the interview. Depressed diabetics showed significantly higher cortisol increases (p < 0.004) than non-depressed diabetics, whereas there was no difference among depressed and non-depressed controls. Depression was not associated with an increase of other hormones or blood glucose levels in both groups. The results of our study confirm specific pathways in which individual emotional arousal and depression may lead to chronic metabolic disturbances as a result of GH and cortisol hypersecretion.

Diabetes support groups improve health care of older diabetic patients

OBJECTIVE

To assess whether knowledge or psychosocial and glycemic benefits of a diabetes education program are enhanced by a support group for older patients.

DESIGN

A partially randomized controlled trial involving two groups of patients: Group A, subjects who received an education program followed by 18 months of support group sessions; Group B, only the diabetes education program. A third convenience sample, Group C, received neither intervention. Groups A and B were assessed before and immediately after the education program, and all groups were assessed 2 years after the education program.

SETTING

Diabetes clinic at a Veterans Affairs Medical Center.

PATIENTS

All subjects were male (mean age = 68 +/- 1.3 years, range = 57-82 years; duration of diabetes = 10 +/- 2 years, range 3-16). Sample sizes were 11 in Group A, 13 in Group B, and 8 in Group C.

INTERVENTION

The education program consisted of six weekly sessions covering aspects of diabetes self-care. The support group consisted of 18 monthly sessions for continuing education, discussion, and structured social activities.

OUTCOME MEASURES

Diabetes knowledge, psychosocial factors (self-care-related quality of life, stress, family involvement in care, and social involvement), depression, and glycemic control.

RESULTS

Group A scored better (at least P less than 0.05) on knowledge, quality of life, and depression than the other groups. Groups A and B showed less stress, greater family involvement, better glycemic control, but less involvement in social activities than Group C.

CONCLUSION

Diabetes education programs can have long term benefits on knowledge, psychosocial functioning, and glycemic control for older diabetic patients. The addition of support groups enhances diabetes knowledge and psychosocial functioning.

Psychiatric morbidity in young adults with insulin-dependent diabetes mellitus

Psychiatric disorder and sub-threshold psychological distress were more common in 113 young men and women with insulin-dependent diabetes living in a defined area than in comparable general population samples. Twelve per cent of men and 19% of women were classified by the PSE as psychiatric 'cases'. Forty per cent of women and 47% of men reported at least one major social problem; effects of diabetes on everyday activities were common. There were associations between medical and social variables. The clinical implications are discussed.

Strategies for evaluating treatments for major depression in primary care patients

Primary care physicians are being urged to provide patients experiencing a major depression treatments validated with psychiatric patients. The propriety of transferring clinical technologies from one care-giving sector to another is questionable, however, as it has little scientific support. We suggest that clinical trials be initiated so as to expand the available knowledge base. This paper analyzes the methodologic issues involved in pursuing such experimental research and urges that it be conducted despite the possible need for initial design compromises.

Behavior of streptozotocin-diabetic mice in tests of exploration, locomotion, anxiety, depression and aggression

The present study examined behavior of streptozotocin-diabetic mice in Porsolt's swim test, a putative animal model of depression, in the holeboard test of exploration and locomotor activity, in the plus maze test of anxiety, and in the resident-intruder paradigm of aggression. Two weeks after an IP injection of 200 mg/kg streptozotocin, which caused a 20% weight loss and increased fluid consumption and urination, male NIH Swiss mice were found to show lengthened duration of immobility in the swim test. One week of insulin treatment (0.1 IU/g/day) partially antagonized this change. The locomotor activity scores in the streptozotocin-treated mice were lower in the holeboard but higher in the plus maze than in the controls; therefore, the lengthened immobility was not likely to be due to a general motor impairment. No significant changes in the time spent in social interaction or aggressive behavior were found in the streptozotocin-treated mice. The results indicate that streptozotocin-treated mice show lengthened immobility in the swim test.

Measures of psychological well-being and treatment satisfaction developed from the responses of people with tablet-treated diabetes

Psychological outcome measures of Well-being and Treatment Satisfaction have been designed and developed for people with tablet-treated Type 2 diabetes. The Well-being scale includes three six-item sub-scales to measure Depression, Anxiety, and Positive Well-being. A prime consideration when selecting items for the psychological well-being measures was to minimize the confounding of diabetic symptomatology with the somatic symptoms of depression and anxiety. Cronbach's alpha indicated that each of the Well-being sub-scales and the Treatment Satisfaction scale was internally reliable (alphas ranged from 0.70 to 0.88) and evidence for construct validity was provided by predicted associations with other variables collected at the time of the study. For example, lower Well-being scores were associated with being overweight (Depression: p less than 0.05; Anxiety: p less than 0.001) while greater Satisfaction with Treatment was associated with lower HbA1 levels (p less than 0.001) and lower percent ideal body weight (p less than 0.01). These scales should prove particularly useful where measures of quality of life are required to complement metabolic variables when evaluating new treatments, education programmes, and other interventions, or in the routine auditing of established methods of treatment.

Effects of self-monitoring of blood glucose on quality of life in elderly diabetic patients

Self-monitoring of blood glucose (SMBG) has been associated with improvement in diabetes knowledge and glycemic control in young and middle-aged diabetic patients. This study investigated the influences of SMBG on the quality of life in 20 older diabetic individuals, aged 60 to 79 years with duration of diabetes 15.6 +/- 2.3 (SD) years. Questionnaires (Cronbach's alpha reliability = .93) were administered regarding the impact of four aspects of diabetic self-care--general factors, diet, medications, and monitoring blood or urine--on quality of life. Each category was scored separately. Data were analyzed comparing individuals using SMBG with those monitoring glycosuria. Older patients showed acceptance of SMBG with respect to performance, lack of time consumption, ease of record keeping, and less embarrassment. Individuals performing SMBG reported better medication compliance than those monitoring glycosuria. No differences were observed between the two groups for general factors, diet, or the overall perception of quality of life. Both groups of patients reported that diabetes and performing self-care techniques did not significantly interfere with their life-style. In conclusion, this study demonstrates that self-care techniques, such as SMBG, do not negatively influence the perception of quality of life in older people.

Psychosocial correlates of hemoglobin Alc in young adults with type I diabetes

To determine whether psychosocial variables are related to long-term glycemic control; trait anxiety, depression, loneliness and life stress were assessed in 48 Type I diabetic patients. Hemoglobin A1c (HbA1c), an indicator of long-term glycemic utilization, was assayed from blood samples drawn shortly before the self-report instruments were administered. Of the psychosocial variables, anxiety was significantly related to current values of HbA1c. The association between anxiety and current HbA1c remained after statistically controlling for potentially confounding variables, including the previous value of HbA1c. Despite the stability of HbA1c values over time, anxiety scores were not significantly correlated with follow-up HbA1c. The implications of the significant relationships between psychological constructs and glycemic control are discussed.

Depressive symptomatology and medical co-morbidity in a primary care clinic

Most primary care patients exhibiting significant depressive symptomatology fail to meet DSM-III criteria for a major depressive disorder (MDD). Yet, such patients have substantial morbidity and dysfunction attributable to their affective syndrome. Since surprisingly little is known about this group's clinical characteristics, we studied 618 general medicine patients aged eighteen to sixty-four years. In this population, fifty-seven (9.2%) scored quite high when screened on the Center for Epidemiological Studies Depression Scale (greater than or equal to 27) while not meeting MDD criteria on the Diagnostic Interview Schedule. Membership in the "depression symptoms only" (DSO) group was predicted by a logistic regression model including female gender, more severe medical illness, higher likelihood of operative procedures, and less frequent cardiovascular diagnoses. Our findings suggest that the DSO state is associated with substantial "medical" morbidity. Prospective studies of subclinical depression in the primary care setting are urged to clarify etiologic and treatment concerns.

A bibliography of the neurobehavioral aspects of diabetes mellitus

Several authors have proposed that diabetes may represent a form of accelerated aging and therefore may be useful as a general model for studying changes with age. It is the purpose of this bibliography to present those research articles which have considered the cognitive or neuropsychological correlates of diabetes mellitus as differentiated from the effects of medical and organismic variables.

The effectiveness of diabetes education programs for older patients and their spouses

Improvements in diabetes knowledge, psychosocial functioning, and metabolic control were assessed following a six-week diabetes education program for older male patients (aged 65 to 82 years) and their spouses. Before and after the program, scored questionnaires were administered to patients and their wives regarding knowledge, quality of life, stress, family involvement in diabetes care, and patient involvement in social activities. The patients were again assessed six months later. Results were compared to those of younger adult male patients (aged 28 to 64 years). The older patients significantly increased their knowledge of diabetes (P less than .05), and to an extent equal to that of younger individuals. Reduction in stress correlated with their increase in knowledge (r = 0.9; P less than .05) and their improved diet-related quality of life (r = 0.7; P less than .02). A decrease in stress was still evident six months after the program P less than .01). Perceived quality of life for areas requiring greater life-style modification (diet and exercise) increased (P less than .01), and was maintained at six months. In contrast, younger patients reported decreases in perceived quality of life (P less than .05). Older patients with participating spouses, compared to those without, showed greater improvement in knowledge (P less than .02), increase in family involvement (P less than .05), less stress (P less than .02), and improvement in metabolic control of diabetes (P less than .001). The program increased spouses' knowledge and perceived involvement in the care of their diabetic partners (P less than .01). This study suggests that diabetes education is an effective intervention for elderly patients and their spouses.(ABSTRACT TRUNCATED AT 250 WORDS)

Affective, substance use, and anxiety disorders in persons with arthritis, diabetes, heart disease, high blood pressure, or chronic lung conditions

The authors estimated the sex- and age-adjusted prevalence of affective, substance use, and anxiety disorders in persons in a general population sample who identified themselves as having arthritis, diabetes, heart disease, high blood pressure, chronic lung disease, or no chronic medical conditions. Persons who reported ever having arthritis, heart disease, chronic lung disease, or high blood pressure had a significantly increased adjusted prevalence of each of the three groups of lifetime psychiatric disorders, relative to a no-chronic conditions comparison group (each p less than 0.05). Persons who ever had diabetes had an increased adjusted prevalence of lifetime affective and anxiety but not substance use disorder. Persons with current (i.e., active) arthritis, heart disease, or high blood pressure had a significantly increased adjusted prevalence of recent (6-month) anxiety disorder, whereas those with current chronic lung disease had an increased adjusted prevalence of recent affective and substance use but not anxiety disorder.

Psychiatric disorders and diabetes--results from a community study

In the Upper Bavarian Field Study a total of 1536 persons (15 years and older) were interviewed by research psychiatrists. The prevalence of diabetes (ICD 250) identified by the interviewer and/or the primary care physician was 4.0%. Since the number of diabetics among the younger age groups was relatively low (n = 7) and in order to obtain a more homogeneous study group, only those over the age of 55 were considered in further analysis. Diabetics were compared with a control group of persons with another chronic medical condition of similar clinical severity and a control group without a somatic disorder. The sex- and age-adjusted prevalence of psychiatric disorders identified with the aid of the Clinical Interview Schedule was significantly higher among diabetics (43.1%) and persons with other chronic medical conditions (50.7%) in comparison to the healthy control group (26.2%). The difference was mainly due to mild psychiatric disorders and those suffering from depression. No statistically significant association was found between diabetes and moderate to severe mental disorders, the use of psychotropic drugs and previous psychiatric treatment.

Counseling patients who have diabetes and psychological problems (continuing education credit)

Patients with diabetes have been found to have a higher incidence of psychiatric symptoms than the general population. Schizo phrenia, major depression, and situational depression are described and relevant counseling skills are introduced to enable the diabetes educator to work more effectively and more comfortably with patients who also have psychological problems. Through the use of nondirective inter viewing and counseling skills, diabetes educators can help patients communicate their feelings and cope more effectively with the compounded problems of diabetes and mental illness.

Depression and diabetes

The incidence and prevalence of depression in diabetic patients in the United Kingdom is unknown. Since depression may influence blood glucose control which in turn may be related to the development of diabetic complications, it is important to estimate its prevalence in diabetic patients. The prevalence of depression was investigated in a group of Caucasian and West Indian, insulin-(IDDM) and non-insulin-dependent (NIDDM) adult diabetics and a non-diabetic comparison group. Prevalence of depression was 8.5% for both groups and a further 19.2% and 14.6%, respectively, had borderline depression. Presence of depression was unrelated to sex, ethnic group, duration or type (IDDM or NIDDM) of diabetes and social class but significantly related to type of accommodation, marital status, and amount of social contact. A higher percentage of diabetics with psychiatric symptoms had one or more current complications compared to 'normal' diabetics. Diabetics suffer from a similar amount of depression to non-diabetics, but psychiatric symptoms may be related to the frequency of diabetic complications.

Depression and diabetic neuropathy: a complex relationship

In a group of 64 non-insulin-dependent diabetic females, a significant positive correlation between Zung self-rated depression scores and objective measurements of diabetic peripheral neuropathy was limited to those women with Zung scores greater than 50 (depressed group, n = 12). In the overall group, there was no significant linear or quadratic relationship between peripheral neuropathy and depression scores. The associations between depression, peripheral neuropathy, and diabetes are discussed.

Initial coping responses and psychosocial characteristics of children with insulin-dependent diabetes mellitus

School-aged children with newly diagnosed insulin-dependent diabetes mellitus (IDDM) were studied longitudinally in order to document how they adjusted to the medical illness and to assess salient background factors. The extent of life stress and the prevalence of psychiatric disorders that predated the IDDM were within normative ranges, and there was no characteristic preexisting "diabetic personality." The initial strain of living with IDDM elicited two general modes of coping. The prototypical and subdued reaction (seen in 64% of the children) consisted of mild sadness, anxiety, feeling of friendlessness, and social withdrawal. The rest of the children (36%) exhibited reactions that met criteria for a psychiatric disorder; depressive syndromes were the most common presentations. Anamnestic factors and the parents' initial responses to their children's IDDM were unrelated to how the children themselves coped. However, psychiatrically diagnosable reactions were more likely among children whose parents were of low socioeconomic status and had marital distress. Coping with the diagnosis and the early impact of IDDM took no more than 7 to 9 months, no matter how severe the child's response was initially.
