The prevalence of depression and anxiety in adults with Type 1 diabetes

Diabulimia: A Risky Trend Among Adults with Type 1 Diabetes Mellitus

OBJECTIVE

Poor adherence leads to worse glycemic control and increased complications in patients with type 1 diabetes mellitus (T1DM). Diabulimia characterizes patients with T1DM who skip or use less insulin for weight loss purposes. The study objectives were to determine: (1) the prevalence of diabulimia among adult patients with T1DM, (2) compare patients with and without diabulimia, and (3) identify factors that may place individuals at higher risk of diabulimia.

METHODS

A 40-item, web-based survey was administered to 21 T1DM discussion boards, Listservs, and social media outlets. The survey assessed demographics, diabetes management, psychiatric diagnoses, and screened for diabulimia. Individuals who reported intentionally skipping or using less insulin than directed for the purpose of weight loss or to prevent weight gain in the past 12 months were classified as having diabulimia.

RESULTS

Of the 225 participants who completed the survey, 8.9% had diabulimia. Patients with diabulimia had elevated hemoglobin A1C (A1C) levels (8.4% vs 6.9%; P = .014), higher rates of a diabetes-related emergency department visits or hospitalization (30.0% vs 13.2%; P = .042), and higher rates of a major depressive disorder diagnosis (40.0% vs 11.5%; P < .001) than patients without diabulimia. Factors associated with diabulimia included high A1C levels (odds ratio, 1.43; 95% CI [1.08-1.91]; P = .014) and a major depressive disorder diagnosis (odds ratio, 4.87; 95% CI [1.31-18.22]; P = .018).

CONCLUSION

Approximately 1 in 11 adult patients with T1DM screened positive for diabulimia. Higher A1C levels and a diagnosis of major depressive disorder were associated with diabulimia.

The impact of hypoglycaemia on quality of life among adults with type 1 diabetes: Results from "YourSAY: Hypoglycaemia"

AIMS

Research on hypoglycaemia and quality of life (QoL) has focused mostly on severe hypoglycaemia and psychological outcomes, with less known about other aspects of hypoglycaemia (e.g., self-treated episodes) and impacts on other QoL domains (e.g., relationships). Therefore, we examined the impact of all aspects of hypoglycaemia on QoL in adults with type 1 diabetes (T1DM).

METHODS

Participants completed an online survey, including assessment of hypoglycaemia-specific QoL (using the 12-item Hypoglycaemia Impact Profile). Mann-Whitney U tests examined differences in hypoglycaemia-specific QoL by hypoglycaemia frequency, severity, and awareness. Hierarchical linear regression examined associations with QoL.

RESULTS

Participants were 1028 adults with T1DM (M ± SD age: 47 ± 15 years; diabetes duration: 27 ± 16 years). Severe and self-treated hypoglycaemia and impaired awareness negatively impacted on overall QoL and several QoL domains, including leisure activities, physical health, ability to keep fit/be active, sleep, emotional well-being, spontaneity, independence, work/studies, and dietary freedom. Diabetes distress was most strongly associated with hypoglycaemia-specific QoL, followed by generic emotional well-being, fear of hypoglycaemia, and confidence in managing hypoglycaemia. Hypoglycaemia frequency and awareness were no longer significantly associated with QoL once psychological factors were considered.

CONCLUSIONS

Hypoglycaemia negatively impacts on several QoL domains. Psychological factors supersede the effect of hypoglycaemia frequency and awareness in accounting for this negative impact.

Viewpoint: Supporting mental health in the current management of rheumatoid arthritis: time to act!

Although clinical outcomes of RA have vastly improved in recent years, the disease's mental health impact has seemingly not decreased to the same extent. Even today, learning to live with RA is an active process involving several psychological, cognitive, behavioural and emotional pathways. Consequently, mental health disorders are more common in the context of RA than in the general population, and can be particularly detrimental both to patients' quality of life and to clinical outcomes. However, mental health is a spectrum and represents more than the absence of psychological comorbidity, and supporting patients' psychological wellbeing should thus involve a more holistic perspective than the mere exclusion or specific treatment of mental health disorders. In this viewpoint article, we build on mechanistic and historical insights regarding the relationship between RA and mental health, before proposing a practical stepwise approach to supporting patients' mental health in daily clinical practice.

Exploring the Interrelationships between Diabetes, Nutrition, Anxiety, and Depression: Implications for Treatment and Prevention Strategies

Across the world, diabetes, depression, and anxiety symptoms have gained widespread recognition as significant public health issues. Recent research has unveiled a mutually influential relationship between diabetes and these two mental health conditions, where each disorder impacts the course and outcomes of the others. The role of nutrition emerges as pivotal in preventing and treating depression, anxiety, and diabetes. A thorough literature review was undertaken to investigate the reciprocal effects between anxiety, depression, and diabetes, including their impact on the development and severity of each condition. Additionally, the effects of nutrition on the prevention and management of depression, anxiety, diabetes, and related complications in at-risk individuals were assessed. Our findings show that mental disorders, such as depression and anxiety, increase the risk of developing type 2 diabetes and are associated with poorer glycemic control, increased diabetes-related complications, and higher mortality rates. Conversely, diabetes is also linked with an increased risk of developing depression and anxiety. The biological, psychological, and social factors that contribute to the comorbidity between these two conditions are complex and multifaceted. Therefore, an integrated approach to the management of both conditions is critical for improving patient outcomes and reducing the overall burden of disease. Nutritional interventions should be utilized to reduce the risk of diabetes in patients with anxiety and depression as well as enhance mental health in patients with diabetes.

Relationship between depressive and anxiety symptoms and fear of hypoglycemia among adolescents and adults with type 1 diabetes mellitus

BACKGROUND AND AIMS

Emotional problems including anxiety, depression and fear of hypoglycemia (FOH) are common in patients with type 1 diabetes mellitus (T1DM). The aim of this study was to determine the prevalence of depressive and anxiety symptoms among patients with T1DM and their relation to glycemic control, diabetes complications and to FOH.

METHODS

This study included 325 patients with T1DM. Anxiety and depressive symptoms were assessed by Hospital Anxiety and Depression Scale (HADS) and FOH was assessed by Hypoglycemia Fear Survey II (HFS-II). Glycemic control was assessed by both fasting plasma glucose and HbA1c. A subsample of 75 patients was screened for diabetes complications.

RESULTS

The prevalence of anxiety symptoms, depressive symptoms and FOH was 76.3%, 61.8% and 20% respectively. Female sex was related to depressive symptoms but not to anxiety symptoms. Logistic regression analysis showed that both HbA1c and HFS-II total score were independently correlated with both anxiety symptoms and depressive symptoms. Age showed independent correlation with both HFS-II (total score) and with Hypoglycemia Fear Survey-worry (HFS-W) while HbA1c showed independent correlation with Hypoglycemia Fear Survey-behavior (HFS-B). Both anxiety and depressive symptoms were positively correlated to HFS-B score, HFS-W score and HFS-II total score.

CONCLUSIONS

FOH is not uncommon among Egyptian patients with T1DM and it seems to be one of the factors contributing to the increased prevalence of anxiety and depressive symptoms among those individuals. Addressing and managing the different psychological aspects of diabetes should be integrated within the routine diabetes care services for people with T1DM.

Neuromodulatory effect of the combination of metformin and vitamin D3 triggered by purinergic signaling in type 1 diabetes induced-rats

Several studies have indicated the vitamin D deficiency in the development of macro- and microvascular complications of diabetes mellitus (DM) including DM-related cognitive dysfunction. The purinergic system plays an important role in the modulation of a variety of mechanisms, including neuroinflammation, plasticity, and cell-cell communication. In addition, purines, their receptors, and enzymes can regulate the purinergic axis at different levels in type 1 DM (T1DM). This study evaluated the effects of vitamin D₃ alone or in combination with metformin in the behavioral performance of streptozotocin-induced T1DM rats. The effects of this combination on the metabolism of ATP and ADP were also studied by NTPDase (CD39), AMP by 5'-nucleotidase (CD73), and adenosine by adenosine deaminase (E-ADA) in the brain and peripheral lymphocytes of type 1 diabetic STZ-induced rats. The results showed that anxiety and memory loss from the DM condition reverted after 30 days of vitamin D₃ treatment. Furthermore, the DM state affected systemic enzymes, with no effect on the central enzymes hydrolyzing extracellular nucleotides and nucleosides. Vitamin D₃ treatment positively regulated ectonucleotidase (NTPDase and 5'-nucleotidase) activity, E-ADA, and the purinergic receptors as a mechanism to prevent oxidative damage in the cerebral cortex of T1DM rats. A neuroprotector effect of vitamin D₃ through adenosine signaling was also observed, by regulating A1 and A_2A receptors proteins levels. The present findings suggest that purinergic signaling through vitamin D₃ modulation may be a novel alternative strategy for T1DM treatment, and may compensate for the negative changes in the central nervous system.

A review of risk factors associated with insulin omission for weight loss in type 1 diabetes

Research suggests that as many as 60% of people with type 1 diabetes (T1D) admit to misusing insulin. Insulin omission (IO) for the purpose of weight loss, often referred to as diabulimia, is a behaviour becoming increasingly recognised, not least since prolonged engagement can lead to serious vascular complications and mortality. Several risk factors appear to be relevant to the development of IO, most notably gender, anxiety and depression and increased weight concerns and body dissatisfaction. Evidence suggests that women, especially young girls, are more likely to omit insulin as a method of weight loss compared to men. Mental health conditions such as anxiety and depression are increasingly prevalent in people with T1D compared to their peers, and appear to contribute to the risk of IO. Increased weight concerns and body dissatisfaction are further prominent risk factors, especially given increases in weight which often occur following diagnosis and the monitoring of weight by diabetes teams. This review presents evidence examining these risk factors which increase the likelihood of a person with T1D engaging in IO and highlights the complications associated with prolongment of the behaviour. Further research looking at the comorbidities of these risk factors, alongside other factors, would provide greater insight into understanding IO in people with T1D.

Psychosocial factors associated with HbA1c in adults with insulin pump-treated type 1 diabetes: a systematic review

AIMS

To identify currently available studies on the association between psychosocial factors and HbA_1c in adults with insulin pump-treated type 1 diabetes, by performing a systematic review of the literature.

METHODS

MEDLINE, Embase, CINAHL and PsycINFO were searched for original studies on the association between psychosocial factors and HbA_1c in ≥ 50 adult, non-pregnant, insulin pump users with type 1 diabetes.

RESULTS

The search resulted in 1777 unique records, of which eight were eligible for inclusion. All identified studies were observational, with sample sizes ranging from 51 to 214. Seven different psychosocial factors were investigated in the eight studies. Study analysis suggested that HbA_1c may be associated with diabetes numeracy and quality of life. There were no indications of associations between HbA_1c and fear of hypoglycaemia or self-efficacy. Results regarding associations between HbA_1c and coping style, diabetes distress and locus of control were inconsistent.

CONCLUSIONS

This systematic review summarizes the currently limited information on the association between psychosocial factors and HbA_1c during insulin pump therapy. The evidence base of the included studies was weak, and this review highlights the need for more research in these areas, with improved methodological and theoretical frameworks, including exploration of a broader spectrum of psychosocial variables and their potential association with HbA_1c and other metabolic outcomes.

Adherence to Medication, Physical Activity and Diet in Older Adults With Diabetes: Its Association With Cognition, Anxiety and Depression

Background

Adherence to medication, physical activity (PA) and diet in diabetes mellitus (DM) patients is crucial for its good management, avoiding acute and chronic complications. There are several risk factors associated with non-adherence, including cognitive impairment, depression and anxiety. Nevertheless, studies on therapeutic adherence in older patients with DM are scarce. In this context, the present study aimed to analyze whether adherence to medication, PA and diet are associated with cognitive impairment, anxiety and depression. It also aimed to identity predictors of medication non-adherence.

Methods

A cross-sectional study of older patients (≥ 65 years old) with DM was carried out in the Outpatient Department of Internal Medicine Service of CHUSJ-Porto, Portugal. Those unable to communicate were excluded. Cognition (mini-mental state examination), anxiety and depression (hospital anxiety and depression scale) were assessed. Adherence to medication, PA and diet was measured, based on self-reporting patient/family, questionnaires, physician clinical opinion, hemoglobin test and pharmacy records. Patient groups were compared, using the Mann-Whitney or the Kruskal-Wallis test for continuous variables and the Chi-square test for paired categorical variables (significance level of 0.05). The odds ratio (OR) was calculated to identify independent predictors of non-adherence to medication.

Results

The final sample (n = 94) had a mean age of 75.2 years (standard deviation: 6.7) and mostly were female (53.2%), married (63.8%) and with a low education level (61.7%). Also, 22.3% with cognitive impairment, 16% with depression and 23.4% with anxiety were found. Patients non-adherent to medication had higher depression (P = 0.048) and anxiety (P = 0.010), compared to adherents/partial adherents. Patients non-adherent to PA showed higher anxiety (P = 0.035) and depression (P = 0.004), compared to adherents. Non-adherents to PA had more cognitive impairment than adherents (26.3% vs. 0%; P = 0.034). Patients who had insulin prescribed presented a higher risk of non-adherence to medication (OR: 4.041, 95% confidence interval (CI): 1.404 - 11.628; P = 0.010). Also, the risk of non-adherence to medication is higher by an increase of one unit in anxiety (OR: 1.252, 95% CI: 1.046 - 1.499; P = 0.014).

Conclusions

Higher anxiety and depression were associated with non-adherence to medication and to PA. Insulin prescribed and high anxiety scores were predictors of medication non-adherence. This study appears to contribute to the knowledge about the influence of cognitive and psychological factors in therapeutic adherence in these older diabetic patients.

Diabetes and anxiety symptoms: A systematic review and meta-analysis

Although some studies have been conducted on the association between diabetes and anxiety symptoms, the data on this association remain controversial. The purpose of this meta-analysis was to examine the association between diabetes and anxiety symptoms. The authors systematically searched PubMed, Scopus, and Google Scholar databases until July 2018. After the screening process, 23 studies were included in the meta-analysis. Stata-14 was used for meta-analyzing. Forest plot was calculated for the whole 23 studies and subgroups, and publication bias was also examined. Overall, diabetes was positively associated with anxiety; pooled odds ratio was equal to1.48; 95% confidence interval was 1 .27-1.74. In cross-sectional study, the result was odds ratio = 1.50; 95% confidence interval = 1.26-1.77, and in prospective-cohort study, the result was odds ratio = 1.34; 95% confidence interval = 1.21-1.49. There was small evidence of publication bias. Overall, our findings indicate that diabetes is a risk factor for anxiety symptoms. Therefore, having a healthy medical condition can be an anxiety prevention agent.

Transcultural, transdiagnostic, and concurrent validity of a revised metacognitions about symptoms control scale

Anxiety and depression add to the burden of chronic fatigue syndrome (CFS), fibromyalgia (FM), and type 1 diabetes mellitus (T1DM). Metacognitions play a role in this distress. The metacognitions about symptoms control scale (MaSCS) measure metacognitive beliefs regarding symptoms but have weaknesses. The current study created a revised MaSCS (MaSCS-R) in English, German, and Arabic versions using CFS, FM, and T1DM samples and examined the transcultural, transdiagnostic, and concurrent validity of metacognitions about symptom control. This study used data from 563 participants clinically diagnosed with CFS (n = 124; English), FM (n = 348; German), or T1DM (n = 91; Lebanese). CFS and FM data had been used in earlier published studies but were subjected to new analyses. CFS data were used to create the English version of the MaSCS-R and FM and T1DM data for German and Arabic versions. Metacognitions about worry, anxiety, depression, and symptom severity were measured. The three MaSCS-R versions, consisting of two factors (each with four items), had adequate psychometric properties, possessing configural and metric invariance. Metacognitive factors were associated with distress and symptom severity in all three samples. Metacognitions about symptom control have transcultural, transdiagnostic, and concurrent validity.

Identification of Psychological Factors Associated with Adherence to Self-Care Behaviors amongst Patients with Type 1 Diabetes

PURPOSE

To explore the factors involved in adherence to self-care behaviors in patients with type 1 diabetes.

MATERIALS AND METHODS

Patients with type 1 diabetes (age range: 14-71 years) were invited to participate at seven Spanish hospitals. They completed a dossier which recorded sociodemographic and clinical variables and also measured personality variables, emotional state, beliefs, and concerns regarding the illness, by means of questionnaires.

RESULTS

A total of 428 patients with type 1 diabetes were included (58% women, age 36 (11.8) years, diabetes duration 18.3 (10.2) years, HbA1c 7.9 +/-1.3%). A total of 60.1% of patients found it difficult to follow the treatment recommendations for the care of their disease. The reasons given were mood (25.2%), lack of motivation (13.4%), work (12%), and economic difficulties (3.8%). Other personal reasons were reported by 5.7%. Motivation, training in diabetes management, importance the patient attributed to the disease, and self-efficacy were the variables that predicted adherence to self-care behaviors, together accounting for 32% of its variance. Anxiety and depression were highly prevalent in this study population (57.1% and 23.1%, respectively) and were associated with lower adherence.

CONCLUSION

In the present study assessing patients with type 1 diabetes, motivation, training in diabetes management, beliefs regarding the disease, and self-efficacy were the main contributors to adherence to self-care behaviors. On the other hand, anxiety and depression were highly prevalent and associated with lower adherence. Thus, supplementing therapeutic education with strategies designed to raise levels of motivation, discussion of beliefs about the disease, and encouragement of self-efficacy might be a useful way to increase patient involvement in self-care.

Reestablishment of the hyperglycemia to the normal levels seems not to be essential to the anxiolytic-like effect induced by insulin

Diabetes is a chronic metabolic disease accompanied by several comorbidities, including neuropsychiatric conditions. Since the hyperglycemia appears to be the primary factor involved in diabetic conditions, we examined the effect of insulin treatment in diabetic rats on behavioral responses related to anxiety and aversive memory extinction. For this, normoglycemic (NGL) or streptozotocin-diabetic (DBT) rats were submitted to the elevated T maze (ETM) and the contextual conditioned fear (CCF) tests. Therefore, animals were subjected to the prolonged treatment with insulin (6 IU/day, s.c.) to investigate the effect of the treatment on distinct behaviors. When anxiety-like responses such as the inhibitory avoidance (IA) on the ETM and the time of freezing in the first session of the CCF test were evaluated, our data showed a more pronounced anxiogenic-like behavior in DBT animals when compared to NGL ones. In addition, an increased freezing time was observed in DBT animals exposed to the CCF test (sessions 2 and 3) when compared to the NGL group, suggestive of an impairment in the extinction of aversive memory. Insulin treatment induced an anxiolytic-like effect when IA and freezing time (session 1) was evaluated, but did not alter the impaired extinction of aversive memory (sessions 2 and 3). To better understand the involvement of a rigorous control of glycaemia, we also investigated the effect of a lower dose of insulin (3 IU/day, s.c.), unable to reestablish the hyperglycemia to the normal levels, on the same behavioral parameters. Our data show that independent of the dose of insulin, the same effects were observed when animals were evaluated in the ETM and CCF tests. However, only the highest dose of insulin was able to reduce the hyperglycemia to the normal levels. To conclude, our data suggest that a severe glycemic control by insulin treatment seems to be important, but not essential in improving diabetes-induced anxiety.

Anxiety symptoms and the risk of diabetes mellitus in Australian women: evidence from 21-year follow-up

OBJECTIVES

This study aimed to explore the association between transitions in anxiety symptoms and the risk of diabetes in women, using longitudinal data.

STUDY DESIGN

This longitudinal study measured diabetes, and transitions in anxiety symptoms, using validated instruments.

METHODS

Data obtained by the Mater-University of Queensland Study of Pregnancy were analysed. Anxiety was measured using the Delusion Symptoms States Inventory (DSSI). To examine possible transitions over different time periods, anxiety was grouped into four categories and assessed at different phases over a 21-year period.

RESULTS

Three hundred and one women reported diabetes 21 years after the index pregnancy. Almost half of the women who reported anxiety symptoms continued to report these at a subsequent follow-up (FU) phase. About 1 in 10 women who had not reported anxiety symptoms at 5-year FU did so at the subsequent 14-year FU. In prospective analyses, we did not find significant association of diabetes with negative transition (no anxiety to anxiety at subsequent phase) or with positive history of anxiety symptom, but an increasing risk was evident. Women with persistent symptoms had a 1.85-fold greater risk of diabetes (95% CI: 1.18-2.90). The cross-sectional analysis did not produce significant results.

CONCLUSIONS

Despite some limitations, this study provides insight into the long-term association between events of anxiety and the risk of diabetes across the reproductive life of women. However, the evidence is not strong enough to support a direct effect of anxiety in causing diabetes.

Insulin reverses anxiety-like behavior evoked by streptozotocin-induced diabetes in mice

Clinical and preclinical data suggest that diabetes is often associated with anxiety. Insulin, a peptide hormone has been reported to have key functions in the brain and in alleviating several psychological impairments, occur as a consequence of diabetes. However, its effects in diabetes-induced anxiety are scanty. The present study examined whether; insulin can reverse the anxiety-like behavior in streptozotocin (STZ)-induced diabetes in mice. After 8-weeks of diabetes induced by STZ (200 mg/kg, intraperitoneally (i.p.)), mice were given insulin (1-2 IU/kg/day, i.p.)/ diazepam (1 mg/kg/day, i.p.)/ vehicle for 14 days and evaluated for behavioral effects in three validated models of anxiety viz. elevated plus maze (EPM), light-dark (L/D) and hole board (HB) tests. STZ-induced diabetic mice elicited significant behavioral effects which include, decreased percentage open arm entries and time in EPM, reduced latency and time spent in light chamber in L/D, decreased number of head dips, squares crossed and rearings in HB tests respectively. Insulin treatment attenuated the behavioral effects evoked by STZ-induced diabetes in mice as indicated by increased open arms activity in EPM, decreased aversion in light chamber during L/D test and increased exploratory behavior in HB test. In conclusion, this study revealed that insulin can reverse anxiety-like behavior in STZ-induced diabetes in mice.

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.

Quality of Life among Egyptian Patients with Upper and Lower Limb Amputation: Sex Differences

Background. Limb amputation is a life-changing event that can cause significant disruptions in many important areas of existence. Aim of this study. To evaluate the quality of life (QOL) of patients with limb amputation and identify the factors affecting the quality of life of patients with limb amputation among Egyptian patients. Research Design. It was a descriptive exploratory design. Setting. The study was conducted in Orthopedics and Surgical Department in Emergency Hospital at Mansoura University Hospitals. Sample. A sample of convenience of 100 adult male and female patients who met the inclusion criteria was included. Tools. (a) Structured interview questionnaire (SIQ) was used to collect personal data, (b) short form (36) health status questionnaires: this part was utilized to assess the quality of life among Egyptian patients with amputation. Results. The result of this study indicates that most participants experienced a change in the quality of life. There is a statistically significant difference between total QOL aspects and each of the following: age, gender, educational level, and type of work. Conclusion. Limb amputation tends to cause increased disability for those amputated patients. The age, gender, place of amputation, and marital status are found as statistically significant factors with physical component and psychological component.

Prevalence and characteristics of depressive disorders in type 1 diabetes

BACKGROUND

Persons with diabetes and depression have increased risk of complications and increased mortality. We aimed to investigate the prevalence, clinical characteristics and impact with regard to glycosylated haemoglobin (HbA1c) of depressive disorders in persons with type 1 diabetes at an outpatient specialist diabetes clinic.

FINDINGS

A total of 51 persons with type 1 diabetes were diagnosed according to Mini International Neuropsychiatric Interview (M.I.N.I) with regard to dysthymia and previous or ongoing depressive episodes during spring 2005. HbA1c was measured at the day of the interview, and self-reported information on family history of depressive disorders was obtained. Eight persons (16%; 95% CI: 7%, 29%) were in the midst of a major depressive episode, 4 of these also reported a previous episode of depression. Seven of the 8 persons with an ongoing major depressive episode met the criteria for melancholia. Three persons (6%) met the criteria for dysthymia, and 6 persons (12%) had previous episode(s) of depression, without being currently depressed. The 17 (33%; 95% CI: 21%, 48%) persons with ongoing and/or previous depressive disorder had increased HbA1c (8.5%; 95% CI: 7.6%, 9.4%) compared to those without depressive disorders (7.9%; 95% CI: 7.5%, 8.3%), although the difference did not reach statistical significance.

CONCLUSIONS

Persons with type 1 diabetes had a high prevalence of depressive disorders, mainly depressive episodes that also met the criteria for melancholia, a subtype often considered a more serious and "biologic" form of depression. We were not able to demonstrate that persons with depressive disorders had poorer regulated diabetes compared to those without depressive disorders.

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.

A psychological support program for individuals with Type 1 diabetes

We aimed to test the effects of a psychological support program on the psychological distress, mood, and quality of life of well-educated individuals with type 1 diabetes. A newly developed support program was offered to 60 patients with type 1 diabetes on intensive insulin treatment, previously enrolled in group-care educational programs. Thirty-three subjects participated (experimental group, in groups of 8-12 subjects); 22, who postponed their entry, were used as controls. The program consisted of 7 weekly work sessions of 2 hours chaired by a psychologist and covered aspects of daily living with diabetes using role-playing, metaplan, and problem solving. At baseline and approximately 6 months later, all participants completed a battery of questionnaires, and the differences between the experimental and the control group were analyzed by repeated-measurements ANOVA. In response to the psychological support program, subjects in the experimental group reduced their depressive mood (Beck Depression Inventory and depression scales of the Psychological Well-Being Index) and anxiety (Self-rating Anxiety Scale), improved disease-specific quality of life (Symptom and Well-Being scales of the Well-Being Enquiry for Diabetes), increased their internal and decreased their external locus of control. These changes were accompanied by a 0.3% decrease in glycosylated hemoglobin, whereas no significant changes were observed in the control group (ANOVA, P = 0.032). These results underline the importance of psychological aspects in individuals with type 1 diabetes; treating the psychological aspects related to the disease may be as important as medical control in order to improve living with diabetes.

Prevalence of depression in consecutive patients with type 2 diabetes mellitus of 5-year duration and its impact on glycemic control

CONTEXT

Type 2 diabetes mellitus doubles the odds of suffering from depressive illness. Co-morbid depression is associated with poorer outcomes in diabetes mellitus in terms of glycemic control, medication adherence, quality of life, physical activity, and blood pressure control.

AIM

The present study aims to estimate the prevalence of depression among a consecutive group of patients with type 2 diabetes and assess its impact on glycemic and blood pressure control.

SETTING

Outpatient department of the endocrinology department of a university affiliated teaching hospital in north India.

SUBJECTS

Consecutive adult patients (18-65 years) with type 2 diabetes mellitus of over 5-year duration with no prior history of psychiatric illnesses or intake of anti-depressants.

MATERIALS AND METHODS

A semi-structured questionnaire was used for demographic data, HbA1c was obtained to assess glycemic control, and blood pressure was recorded twice during patient interview to assess blood pressure control. Depression was assessed with the Major Depression Inventory and scores obtained were classified as consistent with mild, moderate and severe depression. Data was analyzed with SPSS v16, and multiple logistical regression test was done to compare the effect of depression on glycemic control after adjusting for age and sex.

RESULTS

Of the 80 patients interviewed, 31 (38.8%) had depressive symptoms. Among them 20 (25%) had mild depression, 10 (12.5%) had moderate depression, and 1 (1.3%) had severe depression.

CONCLUSIONS

Over one third of patients with type 2 diabetes mellitus of over 5-year duration had depressive symptoms. The presence of depressive symptoms was associated with a significant worsening of glycemic control.

Improved biomedical and psychological outcomes 1 year after structured education in flexible insulin therapy for people with type 1 diabetes: the U.K. DAFNE experience

OBJECTIVE

DAFNE (Dose Adjustment For Normal Eating), a structured education program in flexible insulin therapy, has been widely adopted in the U.K. after validation in a randomized trial. To determine benefits in routine practice, we collected biomedical and psychological data from all participants attending during a 12-month period.

RESEARCH DESIGN AND METHODS

HbA(1c), weight, self-reported hypoglycemia awareness, severe hypoglycemia frequency, PAID (Problem Areas In Diabetes), HADS (Hospital Anxiety and Depression Scale), and EuroQol Group 5-Dimension Self-Report Questionnaire scores were recorded prior to DAFNE and after 1 year.

RESULTS

Complete baseline and follow-up HbA(1c) data were available for 639 (54.9%) of 1,163 attendees. HbA(1c) fell from 8.51 ± 1.41 (mean ± SD) to 8.24 ± 1.29% (difference 0.27 [95% CI 0.16-0.38]; P < 0.001), with a greater mean fall of 0.44% from baseline HbA(1c) >8.5%. Severe hypoglycemia rate fell from 1.7 ± 8.5 to 0.6 ± 3.7 episodes per person per year (1.1 [0.7-1.4]) and hypoglycemia recognition improved in 43% of those reporting unawareness. Baseline psychological distress was evident, with a PAID score of 25.2 and HADS scores of 5.3 (anxiety) and 4.8 (depression), falling to 16.7 (8.5 [6.6-10.4]), 4.6 (0.7 [0.4-1.0]), and 4.2 (0.6 [0.3-0.8]), respectively (all P < 0.001 at 1 year). Clinically relevant anxiety and depression (HADS ≥ 8) fell from 24.4 to 18.0% and 20.9 to 15.5%, respectively.

CONCLUSIONS

A structured education program delivered in routine clinical practice not only improves HbA(1c) while reducing severe hypoglycemia rate and restoring hypoglycemia awareness but also reduces psychological distress and improves perceived well-being.

Correlates of anxiety and depression among patients with type 2 diabetes mellitus

CONTEXT

Research has established the relation between diabetes and depression. Both diabetes and anxiety/depression are independently associated with increased morbidity and mortality.

AIMS

The present study aims at assessing the prevalence of anxiety/depression among outpatients receiving treatment for type 2 diabetes.

SETTINGS AND DESIGN

The study was conducted in the endocrinology outpatient department of an urban tertiary care center.

MATERIALS AND METHODS

The instruments used included a semi-structured questionnaire, HbA1c levels, fasting blood glucose and postprandial blood glucose, Brief Patient Health Questionnaire, and Hospital Anxiety and Depression Scale (HADS).

STATISTICAL ANALYSIS USED

Analysis was carried out using the SPSS version 16.0. Pearson's correlation coefficient was calculated to find out the correlations. ANOVA was carried out for the in between group comparisons.

RESULTS

There was a significant correlation between the HADS-Anxiety scale and Body Mass Index (BMI) with a correlation coefficient of 0.34 (P = 0.008). Also, a significant correlation existed between HADS-Depression scale and BMI (correlation coefficient, 0.36; P = 0.004). Significant correlation were observed between the duration of daily physical exercise and HADS-Anxiety (coefficient of correlation, -0.25; P = 0.04) scores. HADS-Anxiety scores were found to be related to HbA1c levels (correlation-coefficient, 0.41; P = 0.03) and postprandial blood glucose levels (correlation-coefficient, 0.51; P = 0.02).

CONCLUSIONS

Monitoring of biochemical parameters like HbA1c and postprandial blood glucose levels and BMI could be a guide to development of anxiety in these patients. Also, physical exercise seems to have a protective effect on anxiety in those with type 2 diabetes mellitus.

The relationship between adult neuropsychological profiles and diabetic patients' glycemic control

The purpose of this study was to assess, in relation to metabolic control, the cognitive, depressive, and anxiety symptoms among 40 adult patients (age: 18-60 years) with either type 1 (n = 28) or type 2 (n = 12) diabetes mellitus (DM1, DM2). Nineteen healthy subjects matched for age, gender, and education served as the control group. For most cognitive domains, no significant performance differences were found between subjects from the diabetic groups and control subjects. However, diabetes patients demonstrated reduced information processing accuracy along with impaired visual and verbal working memory performance. In addition, psychopathology scores were significantly elevated but did not reach the clinical criteria for depression or anxiety. Overall, there were no significant differences between diabetic subgroups, and no significant correlation was found between cognitive performance, psychopathology scores, and HbA1c values for either subgroup. Thus, patients with DM1 or DM2 may show mild-to-moderate cognitive impairment as well as subtle psychopathological symptoms. While cognitive impairments may be understood in terms of diabetes-associated cognitive dysfunction, psychopathological symptoms may also result from unsuccessful coping with high task demands in everyday life activities. The outcome of the current study underscores the importance of early clinical neuropsychological standardized assessment as well as the diagnosis of cognitive and psychopathological symptoms in adult patients with diabetes.

Moderating effects of coping styles on anxiety and depressive symptoms caused by psychological stress in Chinese patients with Type 2 diabetes

AIMS

This study aimed to assess possible interactive effects of coping styles and psychological stress on depression and anxiety symptoms in Chinese patients with Type 2 diabetes.

METHODS

Three hundred and four patients with Type 2 diabetes underwent a face-to-face interview by trained research staff according to a standardized questionnaire including information on socio-demographic characteristics, psychological stress, coping styles and anxiety and depressive symptoms. The interactive effects of coping styles and psychological stress on depression and anxiety symptoms were assessed by hierarchical multiple regression analyses.

RESULTS

There were significant associations of the four domains of psychological stress with anxiety and depressive symptoms, except for the relationship between 'reduced economic condition' and depressive symptoms. 'Negative coping style' significantly increased the level of both anxiety and depressive symptoms; whereas, 'active coping style' and 'avoidant coping style' decreased the risk of depressive symptoms. The interactions of 'negative coping style' with 'worrying about decline in body/physical function' and 'reduced economic condition' significantly increased the risk of anxiety and depressive symptoms, and the interaction of 'social/family crisis caused by the disease' with 'avoidance coping style' and 'worrying about decline in body/physical function' with 'active coping style' significantly decreased the risk of depressive symptoms.

CONCLUSIONS

The results of this study suggest that certain coping styles might moderate the association of psychological stress with anxiety and depressive symptoms in Chinese patients with Type 2 diabetes.

A cognitive behavior therapy-based intervention among poorly controlled adult type 1 diabetes patients--a randomized controlled trial

OBJECTIVE

To examine the impact of a Cognitive Behavior Therapy (CBT)-based intervention on HbA(1c), self-care behaviors and psychosocial factors among poorly controlled adult type 1 diabetes patients.

METHODS

Ninety-four type 1 diabetes patients were randomly assigned to either an intervention group or a control group. The intervention was based on CBT and was mainly delivered in group format, but individual sessions were also included. All subjects were provided with a continuous glucose monitoring system (CGMS) during two 3-day periods. HbA(1c), self-care behaviors and psychosocial factors were measured up to 48 weeks.

RESULTS

Significant differences were observed with respect to HbA(1c) (P<0.05), well-being (P<0.05), diabetes-related distress (P<0.01), frequency of blood glucose testing (P<0.05), avoidance of hypoglycemia (P<0.01), perceived stress (P<0.05), anxiety (P<0.05) and depression (P<0.05), all of which showed greater improvement in the intervention group compared with the control group. A significant difference (P<0.05) was registered with respect to non-severe hypoglycemia, which yielded a higher score in the intervention group.

CONCLUSION

This CBT-based intervention appears to be a promising approach to diabetes self-management.

PRACTICE IMPLICATIONS

Diabetes care may benefit from applying tools commonly used in CBT. For further scientific evaluation in clinical practice, there is a need for specially educated diabetes care teams, trained in the current approach, as well as cooperation between diabetes care teams and psychologists trained in CBT.

Anxiety and depression levels of patients undergoing liver transplantation and their need for training

The purpose of this research was to determine the levels of anxiety and depression and the need for training of patients who had undergone liver transplantation. This descriptive research included patients who had undergone liver transplantation at least 1 month prior and had follow-up between June and November 2006. The sample consisted of 64 patients who completed a questionnaire consisting of 14 semistructured questions to determine levels of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) developed by Zigmond and Snaith (Acta Psychiatr Scan 67:361, 1983). Paired Student t test was used to assess the need for patient training and to compare the mean scores of the scale Chi-square tests were used for data. Eighty-nine point five percent of anxious patients depressed; numerical 44.4% of those who were not anxietic were depressed. To determine the need for patient training, issues that are worrisome/aggrieving for patients were asked, but a priority of issues was not associated with depression and anxiety of patients. The scale was more sensitive to depression than to anxiety. I will be more appropriate to professionally evaluate anxiety and depression and consider the need for patient training.

Anxiety symptoms in adolescents with type 1 diabetes: association with blood glucose monitoring and glycemic control

OBJECTIVE

To examine the prevalence of anxiety symptoms and their association with blood glucose monitoring (BGM) and glycemic control in adolescents with type 1 diabetes.

METHODS

276 adolescents and their caregivers completed measures of anxiety symptoms. Adolescents completed a measure of depressive symptoms. Demographic and family characteristics were obtained from caregiver report. Diabetes duration, regimen type, BGM frequency, and glycemic control were also collected.

RESULTS

Trait anxiety symptoms that suggest further clinical assessment is needed were present in 17% of adolescents; the rate was 13% for state anxiety symptoms. Higher levels of state anxiety symptoms were associated with less frequent BGM F(14, 261) = 6.35, p < .0001, R(2) = .25, and suboptimal glycemic control, F(15, 260) = 7.97, p < .0001, R(2) = .32. State anxiety symptoms were correlates of BGM frequency and glycemic control independent of depressive symptoms.

CONCLUSIONS

State anxiety symptoms are associated with less frequent BGM and suboptimal glycemic control in adolescents with type 1 diabetes.

Food restriction and streptozotocin differentially modify sensitivity to the hypothermic effects of direct- and indirect-acting serotonin receptor agonists in rats

Food restriction and experimentally-induced diabetes (streptozotocin) can modify serotonin (5-HT) neurotransmission and sensitivity to drugs acting on 5-HT systems. This study examined the effects of food restriction and streptozotocin on the hypothermic effects of the 5-HT(1A) receptor agonist (+)-8-hydroxy-2-(dipropylamino)tetralin hydrobromide (8-OH-DPAT), the 5-HT(2) receptor agonist (+/-)-2,5-dimethoxy-4-methylamphetamine hydrochloride (DOM), the 5-HT releaser fenfluramine, and the selective 5-HT reuptake inhibitor (SSRI) fluoxetine. All four drugs significantly decreased body temperature in free feeding rats. Limiting rats to 10 g/day of food for 7 days decreased body weight and sensitivity to 8-OH-DPAT induced hypothermia, without affecting sensitivity to DOM, fenfluramine, or fluoxetine induced hypothermia. Subsequently, 7 days of free feeding restored body weight and sensitivity to 8-OH-DPAT. Sensitivity to all drugs was significantly decreased 7 days after 50 mg/kg streptozotocin; subsequently, 10 days of insulin replacement restored sensitivity to all drugs. These results extend to body temperature the observation that food restriction and experimentally-induced diabetes differentially modify sensitivity to drugs acting on 5-HT systems and they further suggest that the clinical response to therapeutic drugs acting on 5-HT systems might be impacted by nutritional and insulin status.

Associations between smoking cessation and anxiety and depression among U.S. adults

Many studies have shown a relationship between smoking and depression. However, few studies have examined the association between current depression and smoking and even fewer used large cross-sectional data to support these findings. Using the 2006 Behavioral Risk Factor Surveillance System data (n=248,800), we compared rates of lifetime depression, lifetime anxiety, current depression, and current depressive symptoms among smokers who unsuccessfully attempted to quit (unsuccessful quitters), former smokers (successful quitters), and smokers who made no attempts to quit (non-quitters). Unsuccessful quitters experienced more lifetime depression and anxiety than non-quitters (OR=1.2; 95% CI, 1.0-1.4), whereas successful quitters experienced less (OR=0.7, 95% CI, 0.6-0.8). Current depression prevalence was 14.3% among non-quitters, 18.8% among unsuccessful quitters, and 8.0% among successful quitters. On average, unsuccessful quitters also experienced more days of depressive symptoms during the previous month than either non-quitters or successful quitters. Our results suggest that smokers who attempt to quit unsuccessfully may experience lifetime depression as well as current depression at a higher rate than other smokers and former smokers.

Experience from a behavioural medicine intervention among poorly controlled adult type 1 diabetes patients

AIM

To describe experience from a behavioural medicine intervention among poorly controlled adult type 1 diabetes patients, in terms of feasibility, predictors and associations of improved glycaemic control.

METHODS

Data were collected on 94 poorly controlled adult type 1 diabetes patients who were randomised to a study evaluating the effects of a behavioural medicine intervention. Statistics covered descriptive and comparison analysis. Backward stepwise regression models were used for predictive and agreement analyses involving socio-demographic and medical factors, as well as measures of diabetes self-efficacy (DES), diabetes locus of control (DLOC), self-care activities (SDSCA), diabetes-related distress (Swe-PAID-20), fear of hypoglycaemia (HFS), well-being (WBQ), depression (HAD) and perceived stress (PSS).

RESULTS

The participation rate in the study was 41% and attrition was 24%. Of those patients actually participating in the behavioural medicine intervention, 13% withdrew. From the regression models no predictors or associations of improvement in HbA(1c) were found.

CONCLUSIONS

The programme proved to be feasible in terms of design and methods. However, no clear pattern was found regarding predictors or associations of improved metabolic control as the response to the intervention. Further research in this area is called for.

Anxiety and depression symptoms in patients with diabetes

AIMS

To identify the prevalence and major determinants of anxiety and depression symptoms in patients with diabetes.

METHODS

A cross-sectional study of 2049 people with Types 1 and 2 diabetes, selected from patients experiencing three different models of care in Ireland: (i) traditional mixed care; (ii) hospital/general practitioner (GP) shared care; (iii) structured GP care. Anxiety and depression symptoms were assessed with the Hospital Anxiety and Depression Scale (HADS). Analyses were conducted primarily using logistic regression with adjustment for relevant confounders.

RESULTS

The overall response rate was 71% (n = 1456). Based on the HADS, there was evidence of high levels of anxiety and depression symptoms in patients with diabetes; 32.0% (95% confidence interval = 29.5-34.6%) exceeded the HADS cut-off score of 'mild to severe' anxiety and 22.4% (95% confidence interval = 20.2-24.7%) exceeded the HADS cut-off score of 'mild to severe' depression. Diabetes complications, smoking, uncertainty about glycaemic control and being an ex-drinker or a heavy drinker were risk factors for both higher anxiety and depression scores in multivariate analysis. Female gender and poor glycaemic control were risks factors associated only with higher anxiety scores. Higher socio-economic status and older age were protective factors for lower anxiety and depression scores. Type of diabetes, insulin use, marital status and models of care were not significant predictors of anxiety and depression scores.

CONCLUSIONS

The prevalence of anxiety and depression symptoms in patients with diabetes is considerably higher than in general population samples. These data serve as a benchmark for the prevalence of anxiety and depression symptoms in patients with diabetes.

Association between depression and subclinical carotid atherosclerosis in patients with Type 1 diabetes

AIMS

Recent studies have suggested an association between depression and subclinical atherosclerosis as measured by presence of carotid atherosclerotic plaque and increased intima-media thickening in non-clinical populations. Given the high prevalence of depression in patients with Type 1 diabetes and the diabetes-related risk factors for atherosclerosis, we hypothesized that this relation might also be of special relevance in Type 1 diabetic patients.

METHODS

Intima-media thickness (IMT) and the presence of plaques in the carotid arteries were quantitatively assessed by high-resolution ultrasound in 175 adults (89 men, 86 women) with an established diagnosis of Type 1 diabetes. Having been treated for depression or current Beck Depression Inventory scores > 10 were considered to indicate depression.

RESULTS

In men, the risk of plaque was higher in depressed subjects relative to non-depressed participants after adjustment for age, smoking status, systolic blood pressure, dyslipidaemia and body mass index [odds ratio (OR) 5.19; 95% confidence interval (CI) 1.29, 20.81]. Depressed women did not have an increased risk of plaque compared with non-depressed women (OR 0.97; 95% 95% CI 0.22, 4.34). We did not observe an association between depression and IMT, in men or in women.

CONCLUSIONS

In line with previous research, our findings suggest a link between depression and subclinical atherosclerosis in Type 1 diabetic men, but not in women.

Psychotherapy intervention to reduce depressive symptoms in patients with diabetic foot syndrome

AIMS

Compared to the population as a whole, patients with diabetes mellitus suffer a significantly higher rate of depressive symptoms, especially when they develop complications. Psychotherapy treatments in diabetes mellitus can lead to improvements in both depressive symptoms and glycaemic control. The objective of this study was to investigate whether depressive symptoms can be reduced by psychotherapy treatment delivered as a joint interdisciplinary service to in-patients with diabetic foot syndrome and comorbid depression.

METHODS

Thirty in-patients with diabetic foot syndrome and comorbid depression were randomized to either an intervention group (n = 15) with supportive psychotherapy treatment or a control group (n = 15) that received only standard medical treatment. Patients completed a set of questionnaires at the beginning and end of treatment. These recorded sociodemographic variables, anxiety and depression (Hospital Anxiety and Depression Scale) and diabetes-related problems (Problem Areas in Diabetes Scale).

RESULTS

Although the diabetic foot syndrome improved significantly in 75% of patients, the extent of depressive symptoms and anxiety reported by the control group did not decrease by the end of treatment. In contrast, in the intervention group, anxiety, depression and diabetes-related problems were all reduced. The extent of anxiety and depression was not, as had been anticipated, associated with the severity of the physical symptoms.

CONCLUSIONS

These results indicate that psychotherapeutic intervention during in-patient treatment can have a positive influence on anxiety, depressive symptoms and diabetes-related problems in patients with diabetic foot syndrome.

Prevalence and associations of psychological distress in young adults with Type 1 diabetes

AIMS

To determine the prevalence of psychological distress in young adults with Type 1 diabetes and to explore associated factors.

METHODS

Ninety-two participants with Type 1 diabetes (46 male, 46 female) attending a young adult clinic completed two psychological self-report assessments; the Centre for Epidemiological Studies-Depression Scale (CES-D) and Adult Self-Report Scale (ASR). The mean age was 21.6 +/- 2.8 years (sd) and mean duration of diabetes was 9.3 +/- 5.4 years. A questionnaire identified the method of insulin delivery, the frequency of blood glucose monitoring and hypoglycaemia requiring third-party assistance. HbA(1c) was measured.

RESULTS

Of the participants, 35.2% reported depressive symptoms (CES-D > or = 16), 23.1% indicating severe depressive symptoms (CES-D > or = 24), and 32.2, 40.4 and 35.5% of participants reported significant distress (ASR > or = 60) on the ASR total problem scales, ASR internalizing and ASR externalizing scores, respectively. Mean HbA(1c) levels were higher in participants with depressive symptoms compared with those with normal scores (CES-D > or = 16, HbA(1c)= 9.4% vs. CES-D < 16, HbA(1c)= 8.4%, P = 0.01). Factors associated with psychological distress included use of continuous subcutaneous insulin infusion (CSII) (P = 0.02) and increased frequency of hypoglycaemic episodes (P = 0.03). CSII users had higher CES-D (21.3 vs. 11.9, P = 0.001) and ASR-Total (59.7 vs. 53.0, P = 0.02) scores than non-CSII users.

CONCLUSIONS

Approximately one-third of young adults with Type 1 diabetes experience psychological distress, which is associated with poorer glycaemic control. Psychological distress was related to frequency of hypoglycaemic episodes and method of insulin administration, with significantly greater distress being observed in those using CSII. These findings support inclusion of a psychologist in the diabetes team.

The role of resilience on psychological adjustment and physical health in patients with diabetes

OBJECTIVE

This study used a longitudinal design to investigate the buffering role of resilience on worsening HbA(1c) and self-care behaviours in the face of rising diabetes-related distress.

METHOD

A total of 111 patients with diabetes completed surveys and had their glycosylated haemoglobin (HbA(1c)) assessed at baseline and at 1-year follow-up. Resilience was defined by a factor score of self-esteem, self-efficacy, self-mastery and optimism. Diabetes-related distress and self-care behaviours were also assessed.

RESULTS

Baseline resilience, diabetes-related distress and their interaction predicted physical health (HbA(1c)) at 1 year. Patients with low, moderate and high resilience were identified. Those with low or moderate resilience levels showed a strong association between rising distress and worsening HbA(1c) across time (r=.57, .56, respectively). However, those with high resilience scores did not show the same associations (r=.08). Low resilience was also associated with fewer self-care behaviours when faced with increasing distress (r=-.55). These correlation coefficients remained significant after controlling for starting-points.

CONCLUSION

In patients with diabetes, resilience resources predicted future HbA(1c) and buffered worsening HbA(1c) and self-care behaviours in the face of rising distress levels.

Depression in patients with systemic sclerosis: A systematic review of the evidence

OBJECTIVE

To assess the prevalence, course, and predictors of depression in patients with systemic sclerosis (SSc).

METHODS

We conducted a comprehensive search in November 2006 of MEDLINE, PsycINFO, and CINAHL databases to identify original research studies published in any language that used a structured interview or validated questionnaire to assess major depressive disorder or clinically significant symptoms of depression in patients with SSc. The search was augmented by hand searching 26 selected journals through December 2006 and references from identified articles and reviews. Studies were excluded if only an abstract was provided or if depression was not measured by a validated method.

RESULTS

No studies used a structured clinical interview to assess the prevalence of major depressive disorder. The prevalence of clinically significant depressive symptoms was 51-65% based on 2 studies that used a Beck Depression Inventory (BDI) score >or=10 and 46-56% based on 2 studies that used a BDI score >or=11. These rates and those reported in 4 other studies that used different assessment tools (36-43%) were consistently high compared with other medical patient groups assessed with the same instruments and cutoffs. Methodologic issues limited the ability to draw strong conclusions from studies of predictors.

CONCLUSION

Symptoms of depression are common among patients with SSc. The high rates reported across studies suggest that routine screening is recommended. There is a need for studies that examine depression at different time points from the diagnosis of SSc and that systematically investigate factors associated with high levels of depressive symptoms.
