Sex-related psychological effects on metabolic control in type 2 diabetes mellitus

Social networks, perceived social support, and HbA1c in individuals with type 2 diabetes mellitus in urban Ghana

OBJECTIVES

Although links between social relationships and health are well established, few studies have concurrently examined the effects of compositional, structural, and functional dimensions of social networks on glycemic (HbA1c) control in low- and middle-income countries such as Ghana. In these settings where informal social relationships are critical for access to resources, evaluating the links between social network characteristics, social support, and glycemic control may provide clarity about important relationships that facilitate the well-being of individuals with type 2 diabetes mellitus (T2DM).

DESIGN

In 2018, we conducted a hospital-based, cross-sectional survey of noninstitutionalized adults with T2DM in Ghana. Using data from 247 study participants, multivariable linear regression models were used to estimate associations between: 1) HbA1c and three social network characteristics (kin composition, household composition, and network density); 2) social support and the three social network characteristics; and 3) HbA1c and social support. We also examined gender differences in these associations and applied mediation techniques to determine if network characteristics operated through social support to affect HbA1c.

RESULTS

Findings indicated that higher kin composition and higher household composition were each significantly associated with increased social support. Neither social support nor social network characteristics were significantly related to HbA1c, and there were no gender differences in any of these associations.

CONCLUSION

Although family and household members were identified as important sources of social support for diabetes management, the ways in which they influence HbA1c control among Ghanaians require further investigation. Future studies can examine whether changes in social support over time, social support satisfaction, or other dimensions of social relationships improve T2DM outcomes in countries like Ghana.

[Sex and gender-specific aspects in prediabetes and diabetes mellitus-clinical recommendations (Update 2023)]

Metabolic diseases dramatically affect the life of men and women from infancy up to old age in different and manifold ways and are a major challenge for the healthcare system. The treating physicians are confronted with the different needs of women and men in the clinical routine. Gender-specific differences affect pathophysiology, screening, diagnostic and treatment strategies of diseases as well as the development of complications and mortality rates. Impairments in glucose and lipid metabolism, regulation of energy balance and body fat distribution and therefore the associated cardiovascular diseases, are greatly influenced by steroidal and sex hormones. Furthermore, education, income and psychosocial factors play an important role in the development of obesity and diabetes differently in men and women. Males appear to be at greater risk of diabetes at a younger age and at a lower body mass index (BMI) compared to women but women feature a dramatic increase in the risk of diabetes-associated cardiovascular diseases after the menopause. The estimated future years of life lost owing to diabetes is somewhat higher in women than men, with a higher increase in vascular complications in women but a higher increase of cancer deaths in men. In women prediabetes or diabetes are more distinctly associated with a higher number of vascular risk factors, such as inflammatory parameters, unfavourable changes in coagulation and higher blood pressure. Women with prediabetes and diabetes have a much higher relative risk for vascular diseases. Women are more often morbidly obese and less physically active but may have an even greater benefit in health and life expectation from increased physical activity than men. In weight loss studies men often showed a higher weight loss than women; however, diabetes prevention is similarly effective in men and women with prediabetes with a risk reduction of nearly 40%. Nevertheless, a long-term reduction in all cause and cardiovascular mortality was so far only observed in women. Men predominantly feature increased fasting blood glucose levels, women often show impaired glucose tolerance. A history of gestational diabetes or polycystic ovary syndrome (PCOS) as well as increased androgen levels and decreased estrogen levels in women and the presence of erectile dysfunction or decreased testosterone levels in men are important sex-specific risk factors for the development of diabetes. Many studies showed that women with diabetes reach their target values for HbA_1c, blood pressure and low-density lipoprotein (LDL)-cholesterol less often than their male counterparts, although the reasons are unclear. Furthermore, sex differences in the effects, pharmacokinetics and side effects of pharmacological treatment should be taken more into consideration.

IMAGINE: A Trial of Messaging Strategies for Social Needs Screening and Referral

INTRODUCTION

Health-related social needs are associated with poor health outcomes. Many primary care practices now screen and refer patients with health-related social needs to assistance organizations, but some patients decline screening or assistance. Improving communication about health-related social needs screening and referral could increase screening response and assistance acceptance rates.

STUDY DESIGN

This is a pragmatic, nonrandomized 3-stage trial of messages and communication strategies for health-related social needs screening and referral. Messages and strategies were informed by qualitative analysis of stakeholder interviews and were developed through an iterative, patient-, and stakeholder-engaged process.

SETTING/PARTICIPANTS

Settings included 3 primary care clinics serving primarily low-income patients in western Colorado.

INTERVENTION

Stage 1 includes usual clinic processes for health-related social needs screening (form given to patients at the front desk without additional explanation), Stage 2 includes adding written patient-friendly messages regarding the purpose of health-related social needs screening and referral to usual clinic processes, and Stage 3 includes adding verbal messages delivered by a medical assistant (form given to patients by a medical assistant during the rooming process).

MAIN OUTCOME MEASURES

Primary outcomes include (1) screening form response rate and (2) acceptance of referral for assistance rate among patients with health-related social needs. Secondary outcomes include (1) comfort with screening, (2) perceived helpfulness of screening, and (3) receipt of explanation about screening.

RESULTS

All data collection and analysis occurred in 2021. Study Stage 2 was not associated with significant changes in any outcomes. Stage 3 was associated with decreased odds of screening form response at 2 of the 3 clinics relative to those of Stage 1 (OR=0.1, 95% CI=0.1, 0.3; OR=0.4, 95% CI=0.2, 0.7) but with increased odds of assistance acceptance (OR=2.1, 95% CI=1.1, 4.0) among patients with needs who responded to the screening form. Stage 3 was also associated with higher odds of patients perceiving screening as helpful and receiving an explanation about screening.

CONCLUSIONS

Altering practice workflows to provide verbal explanations of health-related social needs screening may reduce response rates but may encourage responders to accept assistance referrals. Optimal communication strategies and workflows will likely differ depending on the intended goals of health-related social needs screening and referral.

Socio-economic inequalities in glycaemic control in recently diagnosed adults with type 1 and type 2 diabetes

BACKGROUND AND AIMS

It is unclear whether socio-economic status (SES) is associated with glycaemic control in people with recently diagnosed diabetes. The aim was to investigate whether SES is related to haemoglobin A1c (HbA1c) during the first year after diagnosis in people with type 1 and type 2 diabetes and if metabolic, quality of care or mental factors may explain the association.

METHODS

In the German Diabetes Study, people with type 1 (n = 274, median age 36 [25th; 75th percentile: 28; 48] years) and type 2 diabetes (n = 424, 54 [47; 60] years) underwent detailed metabolic characterisation within the first year after diagnosis. SES was documented using a standardised questionnaire. Associations between SES and HbA1c were assessed using multivariable linear regression and restricted cubic spline regression analyses. Additional covariables were patient characteristics, laboratory measurements, health behaviour, quality of care and depression variables. Models were separately fitted for diabetes type, SES and its dimensions (income, education, occupation).

RESULTS

Higher SES score was associated with lower HbA1c (-0.7 mmol/mol per unit increase in SES, 95% CI: -1.1; -0.2 mmol/mol [-0.1%, 95% CI: -0.1; 0.0%]) in people with type 1 diabetes. Included covariates did not attenuate this association. In people with type 2 diabetes, effect estimates were close to zero indicating no relevant difference.

CONCLUSION

Socio-economic inequalities in HbA1c already exist during the first year after diagnosis in people with type 1 diabetes. The absence of association between glycaemic control and SES in type 2 diabetes could be due to the lower complexity of diabetes therapy compared to type 1 diabetes.

Spousal Influence on Diabetes Self-care: Moderating Effects of Distress and Relationship Quality on Glycemic Control

BACKGROUND

Spouses often attempt to influence patients' diabetes self-care. Spousal influence has been linked to beneficial health outcomes in some studies, but to negative outcomes in others.

PURPOSE

We aimed to clarify the conditions under which spousal influence impedes glycemic control in patients with type 2 diabetes. Spousal influence was hypothesized to associate with poorer glycemic control among patients with high diabetes distress and low relationship quality.

METHODS

Patients with type 2 diabetes and their spouses (N = 63 couples) completed self-report measures before patients initiated a 7-day period of continuous glucose monitoring. Mean glucose level and coefficient of variation (CV) were regressed on spousal influence, diabetes distress, relationship quality, and their two- and three-way interactions.

RESULTS

The three-way interaction significantly predicted glucose variability, but not mean level. Results revealed a cross-over interaction between spousal influence and diabetes distress at high (but not low) levels of relationship quality, such that spousal influence was associated with less variability among patients with low distress, but more among those with high distress. Among patients with high distress and low relationship quality, a 1 SD increase in spousal influence predicted a difference roughly equivalent to the difference between the sample mean CV and a CV in the unstable glycemia range.

CONCLUSIONS

This was the first study to examine moderators of the link between spousal influence and glycemic control in diabetes. A large effect was found for glucose variability, but not mean levels. These novel results highlight the importance of intimate relationships in diabetes management.

Social Support, Self-Efficacy, and Psychological Wellbeing of Adults with Type 2 Diabetes

Social support improves self-efficacy, which in turns enhances self-management that lead to better psychological outcomes of persons with type 2 diabetes (T2D). The purpose of this study was to examine the relationship between social support and psychological outcomes of adults with T2D. A cross-sectional design was used to recruit a sample of 339 participants from a diabetes clinic. The participants responded to a series of questionnaires on demographics, social support dimensions, and self-management; self-efficacy; and psychological outcomes. The function and quality of social support were positively associated with self-efficacy. Self-efficacy was significantly associated with both self-management and psychological outcomes. In addition, self-efficacy demonstrated successful mediation role in the relationship between social support and psychological outcomes of T2D, however, self-management failed to mediate this relationship. The quality and functionality of social support are distinctive variables that should be recognized to promote social support interventions to reduce or prevent T2D-related psychological outcomes.

Cognitive illness representation and anxiety in older men and women with type 2 diabetes

AIM

In the elderly, type 2 diabetes is a frequent chronic condition that requires the attention of health care. As patient involvement is a prerequisite for treatment, it seems crucial to assess psychosocial aspects, including patient's cognitive component of attitude towards the condition, as early as upon diagnosis. The aim of this study was to examine whether the cognitive illness representation in older female and male patients with type 2 diabetes is differentiated. Considering disease duration, we determined the effect of cognitive illness representation on older diabetes emotional wellbeing.

METHODS

The study in 99 older adults with type 2 diabetes used Disease-Related Appraisals Scale (Skala Oceny Własnej Choroby; SOWCh) to assess cognitive illness representation and State-Trait Anxiety Inventory (STAI) to assess the severity of state anxiety.

RESULTS

In a subgroup with short-standing diagnosis, women scored significantly higher than men on subscales of Threat, Obstacle/Loss and Profit. In a subgroup with long-standing diagnosis, women scored significantly higher than men on the subscale of Threat and significantly lower than men on the subscale of Value. The associations between the individual dimensions of cognitive illness representation and anxiety were also determined. These correlations differed between sexes and stages of the disease.

CONCLUSION

Both at early and late stages of type 2 diabetes, women perceive their illness as a threat significantly more than men do. This appraisal persists throughout the entire duration of the illness. Men with long-standing diagnosis, attribute higher value to diabetes than women do, perceiving it as an opportunity to appreciate values they did not pay attention to before. Anxiety reported by older women and men can be explained to a significant extent by certain dimensions of their respective cognitive illness representation.

Sex-related differences in self-care behaviors of adults with type 2 diabetes mellitus

PURPOSE

To describe sex-related differences in self-care; to identify determinants of self-care according to sex, and to investigate how sex interacts with the effect of clinical and socio-demographic variables on self-care in adults with Type 2 Diabetes Mellitus (T2DM).

METHODS

Cross-sectional multicentre study with a consecutive sampling recruitment strategy, enrolling 540 adults with T2DM at six outpatient diabetes services. Clinical and socio-demographic variables were collected by medical records. Self-care maintenance, monitoring, management, and confidence were measured by the self-care of diabetes inventory.

RESULTS

Females reported higher disease prevention behaviors (P < 0.001), health-promoting behaviors (P < 0.001), body listening (P < 0.001), and symptom recognition (P = 0.010), but lower health-promoting exercise behaviors (P < 0.001). Determinants of self-care were different in male and female patients, where the role of task-specific self-care confidence predicted self-care monitoring (RR = 0.98; P < 0.001) and management (RR = 0.99; P < 0.001) among males, while persistence self-care confidence predicted self-care maintenance (RR = 0.97; P = 0.016) and management (RR = 0.99; P = 0.009) among females.

CONCLUSIONS

Males and females differently perform self-care. Self-care confidence plays a different role predicting self-care behaviors in males and females. Future research should longitudinally describe self-care and its determinants in males and females with T2DM. Sex-specific self-care confidence interventions should be developed to improve self-care in male and female patients with T2DM.

Elucidating factors associated with non-adherence among Type 1 diabetes patients in primary care setting in Southeastern Brazil

AIMS

To explore the factors associated with adherence and non-adherence to the pharmacological treatment of patients with T1DM in primary care setting southeast Brazil.

METHODS

We conducted a cross-sectional study with 158 patients attending in the primary health care in the city of Franca southeast Brazil and measure adherence to antidiabetic medication. Adherence was measure using Morisky-Green Test modified.

RESULTS

The majority of patients was adherence to antidiabetic medication (63.2%). More than one third of patients were non-adherent treated pharmacologically and comorbidities most prevalent were hypertension (63.8%), dyslipidemia (43.1%) and depression (32.8%). Depression were strongest predictor OR=2.8 (1.2-6.5) of non-adherence.

CONCLUSION

Depression is a factor associated with non-adherence to pharmacological treatment in patients with T1DM, and in clinical practice, screening for depression and intervention as well as pharmaceutical care may improve adherence to pharmacotherapy.

Sex-differences in factors and outcomes associated with adherence to statin therapy in primary care: Need for customisation strategies

Despite the invaluable efficacy of statins, adherence to therapy is extremely poor in clinical practice. Improvement interventions should be as personalized as possible, but it is necessary to know factors that most influence adherence, and sex seems to be a key determinant. Thus, we aimed at exploring potential areas of sex-differences in statin adherence in a real-world population. For this purpose, we assessed adherence (as proportion of days covered) on a wide cohort of new statin users aged >40 years, and we evaluated its association with several covariates through sex-stratified log-binomial regression models. In addition, to compare also the benefits of optimal statin adherence in primary prevention of cardiovascular disease between men and women, we implemented sex-stratified Cox proportional hazard models. Our study showed that women are more likely to stop or be less adherent to statin treatment than men. Moreover, we observed significant sex-differences on effect size of several factors associated with adherence that should be taken into consideration for the management of patients. Finally, we observed no significant difference between men and women regarding statin efficacy in terms of reduction of incident hospitalization for ischemic heart disease and/or non-haemorrhagic cerebrovascular disease. These results invoke the responsibility of physicians to a prompt and personalized intervention. Physicians should consider routine screening for non-adherence in their clinical practice, target patients at higher risk of non-adherence, and improved motivation and communication.

[Sex and gender-specific aspects in prediabetes and diabetes mellitus-clinical recommendations (Update 2019)]

Metabolic diseases dramatically affect the life of men and women from infancy up to old age in different and manifold ways and are a major challenge for the healthcare system. The treating physicians are confronted with the different needs of women and men in the clinical routine. Gender-specific differences affect screening, diagnostic and treatment strategies as well as the development of complications and mortality rates.

Disturbed eating, illness perceptions, and coping among adults with type 1 diabetes on intensified insulin treatment, and their associations with metabolic control

This study investigated associations between psychological aspects and metabolic control among adults with type 1 diabetes ( n = 282). Linear regression analyses demonstrated that the illness perception personal control and the coping strategy seeking emotional social support explained 23.2 percent of the variance in hemoglobin A1c among females ( β = 0.40, p < 0.001 and β = −0.22, p < 0.01, respectively). Among males, only personal control remained significant, explaining 13.9 percent of the variance in hemoglobin A1c ( β = 0.37, p < 0.001). The associations between psychological correlates and hemoglobin A1c indicate that addressing such aspects clinically may facilitate metabolic control, thereby potentially contributing to reduce the risk of complications.

Sex-related illness perception and self-management of a Thai type 2 diabetes population: a cross-sectional descriptive design

BACKGROUND

Increased knowledge concerning the differences in the illness perception and self-management among sexes is needed for planning proper support programs for patients with diabetes. The aim of this study was to investigate the illness perception and self-management among Thai women and Thai men with type 2 diabetes and to investigate the psychometric properties of the translated instruments used.

METHODS

In a suburban province of Thailand, 220 women and men with type 2 diabetes participated in a cross-sectional descriptive study. The participants were selected using a multistage sampling method. Data were collected through structured interviews and were analyzed using group comparisons, and psychometric properties were tested.

RESULTS

Women and men with type 2 diabetes demonstrated very similar experiences regarding their illness perception and no differences in self-management. Women perceived more negative consequences of the disease and more fluctuation in the symptoms than men, whereas men felt more confident about the treatment effectiveness than women. Furthermore, the translated instruments used in this study showed acceptable validity and reliability.

CONCLUSIONS

The Thai sociocultural context may influence people's perceptions and affect the self-care activities of Thai individuals, both women and men, with type 2 diabetes, causing differences from those found in the Western environment. Intervention programs that aim to improve the effectiveness of the self-management of Thai people with diabetes might consider a holistic and sex-related approach as well as incorporating Buddhist beliefs.

Depressive symptoms are associated with poor glycemic control among women with type 2 diabetes mellitus

Objective

In patients with type 2 diabetes mellitus, depressive symptoms may be associated with metabolic deterioration. The impact of sex on this association is unclear. The aim of this study is to analyze the relationship between depression and metabolic control by sex. The data presented is the side product of the clinical investigation by Rui Duarte, MD, Treatment Response in Type 2 Diabetes Patients with Major Depression from 2007.

Results

A sample of 628 outpatients with type 2 diabetes mellitus was taken from a specialized diabetes outpatient clinic. In a univariate analysis: women’s glycohemoglobin mean levels were 8.99% whereas men’s were 8.41% and the difference was statistically significant. The proportion of women (34.3%) with pathological levels of depression (Hospital Anxiety Depression Scale score ≥ 8) was significantly higher than men’s (15.2%). A linear regression analysis performed by sex and controlling for demographic, clinical and psychological variables, showed poorer metabolic control in women with depressive symptoms. No association was observed in men. These results support depression as a predictor for poor metabolic control in women and the need for detecting depressive symptoms when glycemic levels deteriorate.

Sex and gender differences in therapy of type 2 diabetes

Clinical guidelines for the management of type 2 diabetes recommend individual therapy considering age, duration of disease, presence of complication and risk of hypoglycaemia. However, at present, the patient's sex has no impact on clinical decisions. Yet, there is mounting data pointing at biological and psychosocial differences between men and women with great impact on progression of disease and complications. Moreover, choices and preferences of therapeutic strategies as well as adherence to lifestyle and pharmacological interventions differ in both sexes. In addition, drug therapy may have sex-specific side effects. Therefore, there is need of more research on biological differences and of evidence-based individualised targeted sex-sensitive therapeutic concepts. Clinical guidelines must consider relevant sex-differences. Development and implementation of sex-specific programs may help to improve adherence to therapy and to reduce progression of disease and development of complications. A more gender-sensitive clinical approach may improve quality of life and increase health and life expectancy in men and women with type 2 diabetes.

[Sex- and gender-aspects in regard to clinical practice recommendations for pre-diabetes and diabetes]

Metabolic diseases dramatically affect life of men and women from infancy up to old age and are a major challenge for clinicians. Health professionals are confronted with different needs of women and men. This article aims at an increase of gender awareness and the implementation of current knowledge of gender medicine in daily clinical practice with regard to pre-diabetes and diabetes. Sex and gender affect screening and diagnosis of metabolic diseases as well as treatment strategies and outcome. Impaired glucose and lipid metabolism, regulation of energy balance and body fat distribution are related to steroid hormones and therefore impose their influence on cardiovascular health in both men and women. Furthermore, education, income and psychosocial factors relate to development of obesity and diabetes differently in men and women. Males appear to be at greater risk of diabetes at younger age and at lower BMI compared to women, but women feature a dramatic increase of their cardiometabolic risk after menopause. The estimated future years of life lost owing to diabetes is somewhat higher in women than men, with higher increase of vascular death in women, but higher increase of cancer death in men. In women pre-diabetes or diabetes are more distinctly associated with a higher number of vascular risk factors, such as inflammatory parameters, unfavourable changes of coagulation and blood pressure. Pre-diabetic and diabetic women are at much higher relative risk for vascular disease. Women are more often obese and less physically active, but may even have greater benefit from increased physical activity than males. Whereas men predominantly feature impaired fasting glucose, women often show impaired glucose tolerance. A history of gestational diabetes or the presence of a PCOS or increased androgen levels in women, on the other hand the presence of erectile dysfunction (ED) or decreased testosterone levels in men are sex specific risk factors for diabetes development. ED is a common feature of obese men with the Metabolic Syndrome and an important predictor of cardiovascular disease. Diabetic women also feature sexual dysfunctions much more frequently than non-diabetic women which should be addressed in clinical care. Several studies showed that diabetic women reach their targets of metabolic control (HbA1c), blood pressure and LDL-cholesterol less often than their male counterparts, although the reasons for worse treatment outcome in diabetic females are not clear. Furthermore, sex differences in action, pharmacokinetics, and side effects of pharmacological therapy have to be taken into account.

Health Related Quality of Life among Omani Men and Women with Type 2 Diabetes

The aim of this study was to explore predictors of health related quality of life (HRQoL) among men and women with type 2 diabetes. This cross-sectional descriptive study consisted of a random sample of 300 adults with type 2 diabetes in a selected public hospital. Euro-QoL and Revised Summary of Diabetes Self-Care Activities scales were used to collect data between January and June 2010. Schooling and ability to manage positively were highly significant predictors of quality of life (QoL) among women as compared to men. Age, prevention of activities of daily living and knowledge/management of diabetes were significant predictors of Health state among women as compared to men. Findings demonstrate that 30.6% (versus 35.7%) of the variance in the total QoL and 14% (versus 23%) of the variance in health state could be explained by personal and clinical characteristics among women and men, respectively. The study underlines the importance for nurse educators to assess HRQoL among men and women and to develop effective self-care management strategies based on personal and clinical characteristics.

Prediction of therapy response in acromegalic patients under pegvisomant therapy within the German ACROSTUDY cohort

PURPOSE

This study aimed at investigating predicting factors for therapy response under growth hormone receptor antagonist therapy with a focus on subjective and patient-oriented measures.

METHODS

Observational, multicenter nested-cohort study including 271 selected patients with the diagnosis of acromegaly and a minimum of one-year follow-up period within the German ACROSTUDY cohort (total cohort: n = 514). Outcome measures were the change of the biomarker IGF-1 (IGF-1 change and IGF-1 normalisation) between baseline and after 1 year of pegvisomant therapy (12 ± 6 months). Main predictors were patient-assessed subjective measures according to the Patient-Assessed Acromegaly Symptom Questionnaire (PASQ) in conjugation with age, gender, BMI, max. dosage of pegvisomant at follow-up and IGF-1 before the start of pegvisomant therapy.

RESULTS

The mean age of the study population was 51.2 (13.9) years and the mean BMI was 29.5 (5.1) kg/m(2). In adjusted analyses, none of the individual perceived health (PASQ) scores, but age, BMI and IGF-1 at baseline were predictive for an IGF-1 decrease after 1 year of pegvisomant therapy and BMI and IGF-1, but equally none of the PASQ items, were predicting IGF-1 normalisation.

CONCLUSIONS

Age, BMI and baseline IGF-1 but not subjective perceived health measures predict therapy response under second line medical therapy with pegvisomant.

Gender, Illness-Related Diabetes Social Support, and Glycemic Control Among Middle-Aged and Older Adults

OBJECTIVES

This study examined whether the association between illness-related diabetes social support (IRDSS) and glycemic control among middle-aged and older adults is different for men and women.

METHOD

This cross-sectional analysis included 914 adults with diabetes who completed the Health and Retirement Study's 2003 Mail Survey on Diabetes. IRDSS is a composite score of 8 diabetes self-care measures. Hemoglobin A1c levels were obtained to measure good glycemic control (<8.0%). Gender-stratified multivariate log-binomial regression models were used to estimate prevalence ratios and examine the association between IRDSS and glycemic control after controlling for sociodemographic, lifestyle, and clinical characteristics.

RESULTS

The prevalence of good glycemic control was 48.9% among women and 51.1% among men. Mean composite IRDSS scores did not differ by gender. Among women, composite IRDSS was associated with adequate glycemic control (prevalence ratio: 1.06; 95% confidence interval: 1.02, 1.08), and all individual components of IRDSS, with the exception of keeping appointments, were positively associated with adequate glycemic control. No significant associations were observed in men for composite or individual components of IRDSS.

DISCUSSION

Determining the gender-specific impact derived from IRDSS is a worthwhile approach to highlighting factors that differentially predict optimal glycemic control among middle-aged and older adults.

The effect of a Diabetes-Specific Cognitive Behavioral Treatment Program (DIAMOS) for patients with diabetes and subclinical depression: results of a randomized controlled trial

OBJECTIVE

Subclinical depression is one of the most frequent mental comorbidities in patients with diabetes and is associated with a poorer long-term prognosis. Since there is a lack of specific intervention concepts for this patient group, a self-management-oriented group program (DIAMOS [Diabetes Motivation Strengthening]) was newly developed and evaluated in a randomized trial.

RESEARCH DESIGN AND METHODS

DIAMOS is composed of cognitive behavioral interventions aiming at the reduction of diabetes distress. The active control group (CG) received diabetes education. The primary outcome was depressive symptoms. Secondary outcomes were diabetes distress, well-being, self-care behavior, diabetes acceptance, diabetes treatment satisfaction, HbA1c, and subclinical inflammation.

RESULTS

Two hundred fourteen participants (mean age 43.3 ± 13.3 years, female sex 56.5%, type 2 diabetes 34.1%, mean diabetes duration 14.2 ± 10.5 years, HbA1c 8.9 ± 1.8%, BMI 28.7 ± 71 kg/m(2)) were randomized. The 12-month follow-up revealed a significantly stronger reduction of depressive symptoms (Center for Epidemiologic Studies Depression Scale score) in the DIAMOS group compared with the CG (Δ3.9 [95% CI 0.6-7.3], P = 0.021). Of the secondary variables, the Patient Health Questionnaire-9 (Δ1.7 [95% CI 0.2-3.2], P = 0.023), Problem Areas in Diabetes scale (Δ8.2 [95% CI 3.1-13.3], P = 0.002), and Diabetes Distress Scale scores (Δ0.3 [95% CI 0.1-0.5], P = 0.012) displayed significant treatment effects. Moreover, the risk of incident major depression in the DIAMOS group was significantly reduced (odds ratio 0.63 [95% CI 0.42-0.96], P = 0.028). Inflammatory variables were not substantially affected.

CONCLUSIONS

DIAMOS is more effective in lowering depressive symptoms and diabetes-related distress in diabetic patients with subclinical depression. DIAMOS also has a preventive effect with respect to the incidence of major depression.

Health-related quality of life in women and men with type 2 diabetes: a comparison across treatment groups

AIM

This study compares health-related quality of life (HRQL) in patients with type 2 diabetes (T2DM) across treatment groups and explores gender differences.

METHODS

Four regional surveys (KORA, CARLA, SHIP, DHS) and a national survey (GNHIES98) were pooled at individual level. HRQL was assessed with the SF-12/-36v1. Linear regression models were used to assess the effect of T2DM by treatment type (no medication; oral; oral/insulin combination; insulin) on the physical (PCS-12) and mental summary score (MCS-12) and the SF-6D, controlling for age, sex, study and covariates. We also performed an explanatory analysis of single items.

RESULTS

PCS-12 scores and treatment type were associated (P-value 0.006), with lowest values for insulin treatment (-4.44 vs. oral; -4.41 vs. combination). MCS-12 scores were associated with treatment type and gender (P-value <0.012), with lower scores for women undergoing oral (-4.25 vs. men) and combination treatment (-6.99 vs. men). Similar results were observed for SF-6D utilities and single items, related to mental health, social functioning, vitality and role limitation (emotional). Comorbidities were predictors of lower PCS-12 and SF-6D scores.

CONCLUSIONS

T2DM treatment impacts differently on physical and mental HRQL and on women and men. Further studies of gender-specific perceptions of T2DM treatment regimens are needed.

Impact of social determinants of health on outcomes for type 2 diabetes: a systematic review

Social determinants of health include the social and economic conditions that influence health status. Research into the impact of social determinants on individuals with type 2 diabetes has largely focused on the prevention of or risk of developing diabetes. No review exists summarizing the impact of social determinants of health outcomes in patients with type 2 diabetes. This systematic review examined whether social determinants of health have an impact on health outcomes in type 2 diabetes. Medline was searched for articles that (a) were published in English (b) targeted adults, ages 18 + years, (c) had a study population which was diagnosed with type 2 diabetes, (d) the study was done in the United States, and (e) the study measured at least one of the outcome measures-glycemic control, cholesterol (LDL), blood pressure, quality of life or cost. Using a reproducible strategy, 2,110 articles were identified, and 61 were reviewed based on inclusion criteria. Twelve were categorized as Economic Stability and Education, 17 were categorized as Social and Community Context, 28 were categorized as Health and Health Care, and three were categorized as Neighborhood and Built Environment. Based on the studies reviewed, social determinants have an impact on glycemic control, LDL, and blood pressure to varying degrees. The impact on cost and quality of life was not often measured, but when quality of life was investigated, it did show significance. More research is needed to better characterize the direct impact of social determinants of health on health outcomes in diabetes.

Validity and reproducibility of an interviewer-administered food frequency questionnaire in Austrian adults at risk of or with overt diabetes mellitus

Food frequency questionnaires (FFQs) provide an inexpensive tool for dietary assessment. Given the scarcity of data on their validity for nutritional analysis in persons with overt diabetes mellitus or with increased risk of diabetes (relatives of patients with diabetes), this study tests the hypothesis that an FFQ, adapted to local dietary habits, yields a reliable estimate of nutrient intake when compared with 7-day food record (7DR) in healthy, prediabetes, and diabetes cohorts. One hundred three volunteers (50 persons with overt diabetes mellitus, 24 relatives of patients with diabetes, and 29 nondiabetic individuals without a family history of diabetes) completed both FFQ and 7DR. A second FFQ was completed by 100 of these volunteers after 3 months to evaluate its reproducibility. Data were compared by correlation and Bland-Altman analyses. Across the entire group, estimates for gram intakes of nutrients and total energy were associated with wide limits of agreement between FFQ and 7DR (correlation coefficients, 0.23-0.72; P < .02). Compared with 7DR, the FFQ overestimated intakes of saturated fat in the entire group (+6.6 ± 14 g; P < .001) and in persons with overt diabetes mellitus (+7.6 ± 15 g; P < .001) but underestimated protein intake in relatives of patients with diabetes (-16.36 ± 31 g; P = .01). The repeated FFQ revealed variable agreement (correlation coefficients, 0.34-0.72; P < .001) and underestimated (P < .01) macronutrient and total energy intakes, with slightly better performance in persons with overt diabetes mellitus and relatives of patients with diabetes than in nondiabetic individuals without a family history of diabetes. Hence, the FFQ allows measuring intakes of total energy and macronutrients in prediabetes and diabetes cohorts but reveals limitations when assessing dietary composition.

Social support and glycemic control in type 2 diabetes: a systematic review of observational studies

OBJECTIVE

We aim to systematically review observational studies examining the association between social support and glycemic control in adults with type 2 diabetes.

METHODS

We searched MEDLINE, PsycINFO, EMBASE, Scopus, Web of Science and Sociological Abstracts to July 2012 for observational studies investigating the association between structural or functional aspects of social support (social networks, community ties, marital status, family support, perceived, actual, emotional or instrumental social support) and glycemic control (HbA1c).

RESULTS

From electronic and reference searches, 29 studies were eligible. Twenty different assessments of social support were used. Family support and composite measures of support were most frequently associated with reduced HbA1c. There was no evidence for a beneficial effect of other support measures on HbA1c.

CONCLUSION

We found marked variation in population, setting, measurement of social support and definition of outcome, limiting the methodological validity of research. Social support may be important in the management of type 2 diabetes, the need for consensus and standardization of measures is highlighted.

PRACTICE IMPLICATIONS

The presence of informal support should be explored in routine diabetes care.

[Sex- and gender-aspects in regard to clinical practice recommendations for pre-diabetes and diabetes]

Metabolic diseases dramatically affect life of men and women from infancy up to old age and are a major challenge for clinicians. Health professionals are confronted with different needs of women and men. This article aims at an increase of gender awareness and the implementation of current knowledge of gender medicine in daily clinical practice with regard to pre-diabetes and diabetes. Sex and gender affect screening and diagnosis of metabolic diseases as well as treatment strategies and outcome. Impaired glucose and lipid metabolism, regulation of energy balance and body fat distribution are related to steroid hormones and therefore impose their influence on cardiovascular health in both men and women. Furthermore, education, income and psychosocial factors relate to development of obesity and diabetes differently in men and women. Males appear to be at greater risk of diabetes at younger age and at lower BMI compared to women, but women feature a dramatic increase of their cardiometabolic risk after menopause. The estimated future years of life lost owing to diabetes is somewhat higher in women than men, with higher increase of vascular death in women, but higher increase of cancer death in men. In women pre-diabetes or diabetes are more distinctly associated with a higher number of vascular risk factors, such as inflammatory parameters, unfavourable changes of coagulation and blood pressure. Pre-diabetic and diabetic women are at much higher risk for vascular disease (3-6 times compared to non-diabetic women) than diabetic men (2-3 times compared to healthy males). Women are more often obese and less physically active, but may even have greater benefit from increased physical activity than males. Whereas men predominantly feature impaired fasting glucose, women often show impaired glucose tolerance. A history of gestational diabetes or the presence of a PCOS or increased androgen levels in women, on the other hand the presence of erectile dysfunction (ED) or decreased testosterone levels in men are sex specific risk factors for diabetes development. ED is a common feature of obese men with the Metabolic Syndrome and an important predictor of cardiovascular disease. Several studies showed that diabetic women reach their targets of metabolic control (HbA1c), blood pressure and LDL-cholesterol less often than their male counterparts, although the reasons for worse treatment outcome in diabetic females are not clear. Furthermore, sex differences in action, pharmacokinetics, and side effects of pharmacological therapy have to be taken into account.

Gender differences in diabetes self-management among African American adults

The rising incidence of diabetes complications among African Americans is a major health concern. Few studies have addressed gender differences in diabetes self-management in this population. The purpose of this study was to determine whether gender differences in facilitators and barriers to self-management exist among African American adults with type 2 diabetes. Thirty-eight participants were recruited from community agencies and each participated in one of seven audio-recorded focus group sessions. Regular health care visits, positive outlook, prioritization of health, and independence facilitated self-management behaviors in men, whereas acceptance of diabetes was a facilitator for women. Lack of time at work, lack of family support, and lack of knowledge were barriers for men, whereas lack of finances, embarrassment, negative outlook, perceived lack of disease control, and adverse effects of medications were barriers for women. Further research is necessary to design and test gender-specific tailored interventions to improve diabetes self-management in this population.

A psychoeducational intervention (SWEEP) for depressed women with diabetes

BACKGROUND

Clinically significant depression is present in 25 % of individuals with type 2 diabetes, its risk being doubled in women.

PURPOSE

To examine the effectiveness of the Study of Women's Emotions and Evaluation of a Psychoeducational (SWEEP), a group therapy for depression treatment based on cognitive behavioral therapy principles that was developed for women with type 2 diabetes was conducted.

METHODS

Women with significantly elevated depression symptoms (Center for Epidemiologic Studies Depression Scale ≥16) were randomized to SWEEP (n = 38) or usual care (UC, n = 36).

RESULTS

Multilevel modeling indicated that SWEEP was more effective than UC in reducing depression (mean difference of -15 vs. -7, p < .01), decreasing trait anxiety (mean difference of -15 vs. -5, p < .01), and improving anger expression (mean difference of -12 vs. -5, p < .05). Although SWEEP and UC had improvements in fasting glucose (mean difference of -24 vs. -1 mg/dl) and HbA1c (mean difference of -0.4 vs. -0.1 %), there were no statistically significant differences between groups.

CONCLUSIONS

SWEEP was more effective than UC for treating depressed women with type 2 diabetes. Addition of group therapy for depression meaningfully expands the armamentarium of evidence-based treatment options for women with diabetes.

A systematic review of patient-reported and economic outcomes: value to stakeholders in the decision-making process in patients with type 2 diabetes mellitus

BACKGROUND

The need for an approach to measuring health results that incorporates patients' and payers' perspectives has generated a wide range of health care outcomes (HCOs), but it is yet unknown whether these HCOs are appropriate or valid for the health care decision-making process.

OBJECTIVE

The goal of this study was to assess HCOs, patient-reported outcomes (PROs), and economic outcomes in terms of validity and appropriateness to health care decision making in type 2 diabetes mellitus (T2DM).

METHODS

This systematic review of studies published between January 1, 1996, and November 1, 2010, comprised an electronic literature search of MEDLINE and Centre for Reviews and Dissemination databases. Studies included were clinical trials, observational studies, economic analyses, and studies on the development and validation of HCOs in T2DM in the adult population. HCOs were assessed and classified according to their relevance for decision makers in terms of feasibility for routine use, validity, sensitivity, reliability, understanding, and scope.

RESULTS

Two independent reviewers screened 4497 citations. Of these, 281 potentially eligible full articles were retrieved, and 185 met the inclusion criteria. A total of 121 HCOs in T2DM were identified: 80 (66.1%) PROs and 41 (33.9%) economic outcomes. Only 44.6% of the outcomes assessed were appropriate and valid for health care decision making. Greater deficiencies in evidence were found for PROs (61.3%), followed by economic outcomes (43.9%).

CONCLUSIONS

A large number of HCOs are being used in the health care decision-making process, but a significant proportion of these new outcomes have not been properly validated. Despite the fact that appropriate measures will depend on the specific needs of the decision makers, researchers need to use HCOs for which evidence of quality and appropriateness is available.

Sex-specific differences in glycemic control and cardiovascular risk factors in older patients with insulin-treated type 2 diabetes mellitus

BACKGROUND

Because women have been excluded from many study populations in investigations of diabetes care, there is insufficient information on sex-specific differences in glycemic control.

OBJECTIVE

The aim of the present study was to assess whether treatment goals for glycemic and cardiovascular risk factor control are achieved equally in older, Central European, female and male patients with type 2 diabetes mellitus (T2DM).

METHODS

In a retrospective cross-sectional study, data were analyzed from consecutive older (aged ≥60 years) female and male patients with insulin-treated T2DM who attended a diabetes outpatient clinic between January 2007 and April 2008 at the Medical University of Vienna, Austria. Sex-specific differences in glycosylated hemoglobin (HbA₁(c)) levels were assessed as the primary outcome. LDL-C and HDL-C, as well as systolic and diastolic blood pressure (SBP and DBP, respectively), were assessed as secondary outcomes and were adjusted for age, duration of diabetes, duration of insulin treatment, body mass index, insulin units per kilogram per day, and secondary causes of diabetes. P values were adjusted using the Bonferroni correction.

RESULTS

Data were analyzed from 183 female and 209 male patients with insulin-treated T2DM. In multivariate linear regression models, women had significantly higher levels of LDL-C (P = 0.008), HDL-C (P < 0.001), SBP (P < 0.001), and DBP (P = 0.034), but not HbA₁(c) (P = NS). Multivariate logistic regression models revealed that women were significantly less likely to meet treatment goals for blood pressure (SBP, P = 0.044; DBP, P = 0.024), but not for cholesterol or HbA₁(c) levels (P = NS for LDL-C, HDL-C, and HbA₁(c)).

CONCLUSION

In this study of older patients with insulin-treated T2DM, whereas glycemic control was comparable between women and men, a more adverse cardiovascular risk factor profile was observed in female patients.

Measuring health-related quality of life in non-complicated diabetes patients may be an effective parameter to assess patients at risk of a more serious disease course: a cross-sectional study of two diabetes outpatient groups

AIM

To describe health-related quality of life in diabetes outpatients and investigate the impact of diabetic foot ulcers, by comparing a group of patients with and without diabetic foot ulcers complications. Secondary to study the impact of sociodemographic and clinical variables in the two groups.

DESIGN

Cross-sectional study.

METHODS

The study involved 130 diabetes outpatients and 127 diabetic foot ulcers patients. Health-related quality of life was measured with the generic questionnaire Short Form-36, consisting of eight dimensional scores. All scores were adjusted for differences in age and gender (estimated marginal means). Differences were compared with anova calculations, by the use of Predictive Analytics Software, PASW (version 17.0).

RESULTS

This study confirms that health-related quality of life differs significantly between disease subgroups when measured with Short Form-36. Diabetic foot ulcers had a major negative impact on 7/8 subscales on the Short Form-36 compared to the diabetes outpatients group. health-related quality of life decreased with increasing amount of complications and comorbidity in the diabetes outpatients group, with cardiovascular complications being the most pronounced predictor of lower health-related quality of life scores.

CONCLUSION

Patients who have developed diabetic foot ulcers reports much poorer health-related quality of life than compared to diabetes outpatients. Factors linked to the development of late complications were not detected in the diabetic foot ulcers group, such as cardiovascular comorbidity and neuropathy.

RELEVANCE TO CLINICAL PRACTICE

Health-related quality of life measurement in early stages of disease may detect patients at risk of a more serious disease course and who consequently are in need of a more intensive follow-up.

Coping style and depression influence the healing of diabetic foot ulcers: observational and mechanistic evidence

AIMS/HYPOTHESIS

Experimental evidence suggests that the healing of diabetic foot ulcers is affected by psychosocial factors such as distress. We examined this proposal in a prospective study, in which we considered the role of psychological distress and coping style in the healing of diabetic foot ulcers over a 24 week period. We also explored the role of salivary cortisol and matrix metalloproteinases (MMPs) as potential mechanisms.

METHODS

For this prospective observational study we recruited 93 (68 men; mean age 60 years) patients with neuropathic or neuroischaemic diabetic foot ulcers from specialist podiatry clinics in secondary care. Clinical and demographic determinants of healing, psychological distress, coping, salivary cortisol and both MMP2 and MMP9 were assessed at baseline. Ulcers were assessed at baseline and at 6, 12 and 24 weeks post-baseline. The primary outcome was ulcer status at 24 weeks, i.e. healed vs not healed.

RESULTS

After controlling for clinical and demographic determinants of healing, ulcer healing at 24 weeks was predicted by confrontation coping, but not by depression or anxiety. Patients with unhealed ulcers exhibited greater confrontation coping (model including depression: OR 0.809, 95% CI 0.704-0.929, p = 0.003; model including anxiety: OR 0.810, 95% CI 0.704-0.930, p = 0.003). However, change in ulcer size over the observation period was associated with depression only (p = 0.04, d = 0.31). Healed ulcers by 24 weeks were also associated with lower evening cortisol, higher precursor MMP2 and a greater cortisol awakening response.

CONCLUSIONS/INTERPRETATION

Confrontation coping and depression predict ulcer healing. Our preliminary enquiry into biological mechanisms suggests that cortisol and precursor MMP2 may underlie these relationships.

Family influences on self-management among functionally independent adults with diabetes or heart failure: do family members hinder as much as they help?

OBJECTIVES

Among functionally independent patients with diabetes or heart failure, we examined family member support and family-related barriers to self-care. We then identified patient characteristics associated with family support and family barriers and how each was associated with self-management adherence.

METHODS

Cross-sectional survey of 439 patients with diabetes or heart failure (74% response rate).

RESULTS

75% of respondents reported supportive family involvement in self-care; however, 25% reported frequent family-related barriers to self-care. Women reported family support less often (64% v. 77%) and family barriers to self-care more often (30% v. 21%) than men. 78% of respondents reported involved family members nagged or criticized them about illness care. In multivariate models, low health literacy, partnered status and higher family function were associated with higher family support levels, while female gender, older age, higher education, and more depression symptoms were associated with family barriers to self-care. Family barriers were associated with lower disease care self-efficacy (p<0.01), and both barriers and family support were associated with patients' self-management adherence (both p<0.05).

DISCUSSION

Family members are highly involved in the self-care of these higher functioning patients. Interventions should help patients with chronic illness overcome family barriers to self-care and help families use positive and effective support techniques.
