Factors Affecting Fatigue in Patients with Type II Diabetes Mellitus in Korea

Prevalence and correlates of insomnia and fatigue in patients with type 2 diabetes in Jordan

Objective: The present study examined the prevalence and correlates of insomnia and fatigue in patients with type-2 diabetes in Jordan.Methods: This was a cross-sectional online study involving a convenience sample of 390 patients with type-2 diabetes. Insomnia was assessed by the Insomnia-Severity Index (ISI-A) and fatigue by the Brief Fatigue Inventory (BFI-A).Results: Severe insomnia was present in 132 patients (33.8%), and was correlated with length of diabetes (diagnosis >5 years) (OR = 2.13, 95% CI = 1.19-3.81, P = 0.01), presence of uncontrolled diabetes (OR = 1.97, 95% CI = 1.45-2.69, P < 0.001), taking gabapentin (OR = 2.07, 95% CI = 1.07-4.01, P = 0.003), and age (<40 years) (OR = 0.30, 95% CI = 0.13-0.69, P = 0.005). Significant fatigue was also prevalent and correlated with gender (female) (B = 9.25, t = 4.48, P < 0.001), age (<40 years) (B = 7.56, t = 2.56, P = 0.01), a diagnosis of hypertension (B = 4.74, t = 2.03, P = 0.04), uncontrolled diabetes (B = 7.21, t = 4.82, P < 0.001), and taking a sulfonylurea (B = 8.03, t = 3.37, P < 0.001), carbamazepine (B = 10.93, t = 2.65, P = 0.008), or gabapentin (B = 12.60, t = 3.83, P < 0.001).Conclusion: Given the high prevalence of insomnia and fatigue in this population, increased attention by primary healthcare providers to these symptoms in diabetic patients is required, particularly in developing countries such as Jordan.

Impact of Fatigue and Its Influencing Factors on Diabetes Self-Management in Adults With Type 2 Diabetes: A Structural Equation Modeling Analysis

PURPOSE

The purposes of this study were to (1) examine the relationships between fatigue, its influencing factors, and diabetes self-management and (2) test the mediation effects of fatigue on the link between the influencing factors and diabetes self-management in adults with type 2 diabetes.

METHODS

This cross-sectional, correlational study was guided by the theory of unpleasant symptoms. Data were collected using structured questionnaires. Fatigue was measured by the Fatigue Symptom Inventory and the Multidimensional Fatigue Inventory. Diabetes self-management was measured by the Summary of Diabetes Self-Care Activities. From March to July 2021, a convenience sample of 150 participants was recruited from 2 diabetes outpatient clinics of a regional hospital in Taiwan. Data were analyzed using structural equation modeling.

RESULTS

A more recent diagnosis of diabetes, more depressive symptoms, and lower sleep quality were related to higher fatigue. Higher fatigue correlated with less performance in diabetes self-management. Fatigue mediated the relationship between depressive symptoms, sleep quality, and diabetes self-management.

CONCLUSIONS

Fatigue had a mediating effect on the link between psychological influencing factors and diabetes self-management. Future development of fatigue interventions integrating depressive symptoms and sleep management will likely increase the performance of diabetes self-management and improve the health outcomes in adults with type 2 diabetes. The study tested the theory of unpleasant symptoms using empirical data and will assist in building theory-guided fatigue interventions to improve diabetes self-management in people with type 2 diabetes.

Effects of Insulin Combined with Traditional Chinese Medicine Assisted Comprehensive Nursing Intervention on Oxidative Stress State, Cell Adhesion Factor, and Pregnancy Outcome of Patients with Gestational Diabetes Mellitus

Objectives

The changes of oxidative stress state, cell adhesion factor (sICAM-1) level, blood glucose, and blood lipid of patients with gestational diabetes mellitus (GDM) assisted by insulin combined with traditional Chinese medicine (TCM) prescription were detected to explore the effect of TCM treatment on maternal and infant outcomes of GDM.

Methods

A total of 60 patients diagnosed with GDM from January 2019 to December 2019 were selected. Among them, 30 patients were treated with insulin combined with TCM prescription (control group), and 30 patients were treated with nursing intervention based on control group (study group). Serum of maternal vein and fetal umbilical vein was collected. The contents of superoxide dismutase (SOD) and lipid oxide (MDA) were determined. The content of intercellular adhesion factor (ICAM-1) was measured, and the differences of fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c), triglyceride (TG), cholesterol (CHO) and low density lipoprotein (LDL-C) between 2 groups were compared. The incidence of maternal and infant adverse outcomes was assessed.

Results

After treatment, blood glucose indexes in 2 groups were decreased, and the study group was lower than the control group. After treatment, LDL-C, TC and TG in 2 groups were lower than before, and the study group was lower than the control group. HDL-C was higher than before treatment, and the study group was higher than the control group. After treatment, oxidation-related substances SOD and GSH-Px in 2 groups were higher than before, and those in study group were higher than those in control group. ROS and MDA were lower than before treatment, and the level of sICAM-1 in the study group was significantly higher than that in the control group. Clinical application of insulin combined with TCM prescription assisted comprehensive nursing intervention in the treatment of gestational diabetes, pregnancy outcome is improved.

Conclusions

Oxidative stress imbalance exists in GDM and the causes of adverse pregnancy outcomes are closely related to oxidative stress and vascular endothelial injury. TCM can improve the oxidative stress imbalance and the pregnancy outcome of patients with GDM from the perspective of reducing vascular endothelial injury. Comprehensive nursing intervention for pregnant women with GDM can optimize the outcome of pregnancy and is worthy of clinical application.

An integrative review of fatigue in adults with type 2 diabetes mellitus: Implications for self-management and quality of life

AIMS AND OBJECTIVES

To synthesise empirical studies on factors related to fatigue and its impact on diabetes self-management (DSM) and quality of life (QOL) in adults with type 2 diabetes mellitus (T2DM).

BACKGROUND

Fatigue is commonly reported in people with T2DM, a chronic condition that is highly prevalent worldwide. However, a holistic understanding of the consequences and factors related to fatigue in adults with T2DM is not well synthesised.

DESIGN

This integrative review used Whittemore and Knafl's methodology and was reported according to the Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and checklist.

METHODS

The theory of unpleasant symptoms (TOUS) was used as a conceptual model to guide the review. The PubMed, PsychINFO and CINAHL databases were searched to identify studies that recruited adults with T2DM, were peer-reviewed, written in English and investigated fatigue as a primary or secondary outcome. Two investigators independently appraised the quality of the studies and extracted the data.

RESULTS

Twenty-nine articles met the inclusion criteria: 23 observational studies, two randomised controlled trials, one quasi-experimental study and three qualitative studies. All articles were of high quality. Physiological (e.g. T2DM duration, complications and inflammatory biomarkers), psychological (e.g. diabetes distress, depression and sleep quality) and situational factors (e.g. race/ethnicity, education and social support) were related to fatigue. Studies reported fatigue as a barrier to physical activity, healthy eating behaviours and the physical aspect of QOL.

CONCLUSIONS

Multiple factors are related to fatigue in adults with T2DM. Gaps in the literature include the multiple dimensions of fatigue, the effectiveness of interventions to alleviate fatigue and fatigue experiences in under-represented populations.

RELEVANCE TO CLINICAL PRACTICE

This integrative review supports the complex origin of fatigue and its impact on adults with T2DM. Nurses should evaluate modifiable factors related to fatigue and provide support to help improve DSM and QOL in this population.

Diagnosis of Muscle Fatigue Using Surface Electromyography and Analysis of Associated Factors in Type 2 Diabetic Patients with Neuropathy: A Preliminary Study

Diabetic neuropathy (DN) is a major complication associated with diabetes mellitus (DM) and results in fatigue. We investigated whether type 2 diabetic patients with or without neuropathy experienced muscle fatigue and determined the most influencing factor on muscle fatigue. Overall, 15 out of 25 patients with type 2 DM were diagnosed with DN using a nerve conduction study in the upper and lower extremities, and the composite score (CS) was calculated. We obtained the duration of DM and body mass index (BMI) from subjects, and they underwent a series of laboratory tests including HbA1c, fasting plasma glucose, triglycerides, and high- and low-density lipoprotein. To qualify muscle fatigue, this study used surface electromyography (sEMG). Anode and cathode electrodes were attached to the medial gastrocnemius. After 100% isometric maximal voluntary contracture of plantarflexion, the root mean square, median frequency (MDF), and mean power frequency (MNF) were obtained. We showed a correlation among laboratory results, duration of DM, BMI, CS, and parameters of muscle fatigue. The duration of DM was related to fatigue of the muscle and CS (p < 0.05). However, CS was not related to fatigue. The MDF and MNF of muscle parameters were positively correlated with HbA1c and fasting plasma glucose (p < 0.05). In conclusion, we suggest that the duration of DM and glycemic control play important roles in muscle fatigue in patients with DN. Additionally, sEMG is useful for diagnosing muscle fatigue in patients with DN.

Contributing factors of fatigue in patients with type 2 diabetes: A systematic review

Remarkable evidence supports the link between type 2 diabetes (T2DM) and fatigue. However, a unifying recommendation to identify and prevent fatigue or to prevent its clinical consequences in T2DM is not available at present. Therefore, this study aimed to conduct a systematic review to summarize the definition, measurement tools, and contributing factors of fatigue in T2DM. Nine articles were included for analysis, and results showed that T2DM fatigue was associated with five major factors, including sociodemographic factors, clinical disease factors, inflammatory factors, psychological factors, and behavior and lifestyle. The contributing factors of T2DM fatigue are reviewed, and clinical benefits provide a theoretical basis for further clinical intervention to prevent the occurrence of fatigue and improve the patient's treatment compliance and self-management ability and may be beneficial to their quality of life.

Determinants of Quality of Life in Individuals With a Dual Diagnosis of Resectable Pancreatic Cancer and Diabetes Mellitus

OBJECTIVES

To explore the associations among clinical characteristics, fatigue, diabetes mellitus (DM) self-care activities, and quality of life (QOL) in individuals with resectable pancreatic cancer and DM.

SAMPLE & SETTING

57 individuals with resectable pancreatic cancer and DM from an outpatient pancreatic surgical department in Taiwan were included in the final analysis.

METHODS & VARIABLES

A cross-sectional, correlational design was used. QOL, fatigue, and DM self-care were measured by the European Organisation for Research and Treatment of Cancer QOL Questionnaire-Core 30, the Fatigue Symptom Inventory, and the Summary of Diabetes Self-Care Activities.

RESULTS

Participants who had a shorter duration of DM and higher levels of fatigue (including intensity, duration, and interference) reported lower QOL scores. Participants who performed more DM self-care activities and physical activity per week had higher QOL scores. Fatigue, DM self-care activities, and DM duration were significant factors related to QOL.

IMPLICATIONS FOR NURSING

Shorter DM duration, increased fatigue, and fewer DM self-care activities were determinants of worse QOL in individuals with resectable pancreatic cancer and DM.

Real-Time Associations Between Glucose Levels and Fatigue in Type 2 Diabetes: Sex and Time Effects

OBJECTIVE

Fatigue is a pervasive and serious complaint among aging adults with type 2 diabetes. Anecdotally, hyperglycemia was thought to cause fatigue, but prior cross-sectional analyses failed to find any relationship between glucose levels and fatigue. However, study methodology may have caused this relationship to be missed. Our aim was to use concurrent and continuous data across 5 days to examine real-time momentary relationships between glucose and fatigue levels by week, day, and time of day. Additionally, we explored how these relationships differed by sex.

METHOD

Participants (N = 54, 51% male, 54% non-White) wore continuous glucose monitors and wrist actigraphy into which they inputted fatigue ratings 6-8 times daily during waking hours across 5 days. Generalized estimation equation models were used to explore the relationship between glucose and fatigue when averaged by week, day, and time of day. Differences by sex were also explored.

RESULTS

HbA1c and baseline and real-time fatigue were higher in women than in men. Baseline HbA1c and self-reported general fatigue were unrelated. Fatigue levels averaged by day and time of day were higher in women than in men (p < .05). Glucose and fatigue were significantly related at all levels of data (weekly, daily, and time of day) in women but not men.

CONCLUSIONS

Our findings suggest that, when measured concurrently, glucose excursions may affect fatigue levels in women.

Fatigue-Related Factors for Community-Dwelling Older Adults with Diabetes: A Theory-Guided Multi-Dimensional Approach Using the Dynamic Biopsychosocial Model

Older adults with diabetes appear more susceptible to fatigue compared to younger adults with diabetes or healthy older adults, since aging and diabetes independently and synergistically influence fatigue. Few studies have investigated fatigue in older adults with diabetes using a multidimensional approach. This study explored the influences of physical, psychological, interpersonal, and contextual factors on diabetes fatigue using a dynamic biopsychosocial model. Face-to-face surveys were administered to community-dwelling older adults with diabetes and included variables across four domains (i.e., physical, psychological, interpersonal, and contextual factors). Univariate analyses and multiple linear regression were used. The mean fatigue score was 3.94 (standard deviation (SD) = 1.81) out of 7, and the prevalence of fatigue was 48.8%. Significant differences in fatigue severity by psychological, interpersonal, and contextual factors were found. Comorbidity and psychological factors were significant predictors of fatigue in the model, explaining 31.9% of the variance. As nearly half the sample experienced moderate or severe fatigue, which was significantly influenced by both comorbidity and psychological factors, including depression, sleep quality, and diet-related psychological characteristics, assessing patients' psychological status may be important. Awareness of fatigue could be incorporated into dietary interventions for older adults with diabetes.

The association of diabetes-related self-care activities with perceived stress, anxiety, and fatigue: a cross-sectional study

PURPOSE

Many people with type 2 diabetes (T2DM) do not sustain sufficient diabetes-related self-care activities (DRSCA) in their daily lives. To provide additional information about the positive influence of DRSCA, this study was conducted to examine whether DRSCA were associated with reduced perceived stress, anxiety, and fatigue among people with T2DM and to explore the level of DRSCA, perceived stress, anxiety, and fatigue and their association with background information.

PATIENTS AND METHODS

This study was a cross-sectional survey including 251 participants aged 18 years and older recruited from two hospitals in the eastern part of China. The study utilized self-report questionnaires that consisted of background information, DRSCA, perceived stress, anxiety, and fatigue. Hierarchical multiple regression analysis was conducted to explore the association of DRSCA with perceived stress, anxiety, and fatigue while adjusting for background information.

RESULTS

The results indicated that the level of self-care activities, stress, and fatigue was around middle level. The prevalence of anxiety was 19%. A high level of DRSCA was likely to reduce perceived stress but was not linked to anxiety and fatigue. Women were more susceptible to stress and anxiety, and people who had diabetes for >5 years were more likely to have anxiety. The background information included diabetes duration, standardized diabetes education, and high social support, all of which are factors that may influence DRSCA.

CONCLUSION

The findings suggest that improving the level of DRSCA might effectively reduce perceived stress. The potential benefits of DRSCA can provide both motivational and evaluative data for self-care programs. In addition, the findings show that DRSCA were not linked to anxiety and fatigue, which implies that their positive influence on anxiety and fatigue may be offset by the load of frequent DRSCA. It is suggested that helping patients to make tailored plans to integrate DRSCA into their daily lives is needed. Meanwhile, in the background information, it is suggested that standardized diabetes education and high social support can benefit DRSCA; in improving psychological health, more attention should be paid to women and patients with diabetes duration <5 years.

Validity and reliability of functional assessment of chronic illness treatment-fatigue scale in Turkish patients with type 2 diabetes

BACKGROUND

A long-term diabetic complication, fatigue, which is a direct result of treatment and psychological processes, is a common symptom in diabetic individuals.

AIMS

To determine the reliability and validity of Functional Assessment of Chronic Illness Treatment-Fatigue Scale in Turkish patients with type 2 diabetes.

STUDY DESIGN

A methodological study.

METHODS

The sample consisted of 133 patients with type 2 diabetes who agreed to participate in the study and met the criteria for the study. Data were collected using the descriptive information form prepared by the researcher and the Scale obtained from FACIT System. The research data were collected by face-to-face interviews with the patients. Language and content validity of the Turkish version of the Scale was provided, Cronbach's Alpha coefficient, test-retest analysis and item analysis methods were used as reliability analysis.

RESULTS

The total Cronbach Alpha coefficient of the scale was found to be 0.92. According to the results of factor analysis, unlike the original scale, two sub-dimensions emerged in the Turkish version of the scale.

CONCLUSIONS

As a result of the validity and reliability analysis of the FACIT-Fatigue Scale, it can be said that it provides psychometric measures that can be used to determine the level of fatigue of type 2 diabetes patients in Turkish society.

The Contribution of Vascular Risk Factors in Prevalence of Fatigue Four Years Following Stroke: Results from a Population-Based Study

BACKGROUND

Fatigue is a debilitating symptom after stroke, which may persist for many years. Survivors of stroke commonly have comorbid medical conditions such as hypertension and diabetes mellitus that may produce fatigue by themselves. The contribution of vascular and other risk factors on long-term poststroke fatigue (PSF) has not been sufficiently investigated at a population-based level.

METHODS

Adults (N = 256) with stroke, who consented into the Auckland Regional Stroke Outcomes Study (ARCOS-IV), completed assessments including the Fatigue Severity Scale (FFS) at 4 years poststroke. A mean score greater than 4 was indicative of fatigue. A multiple regression model identified baseline associations (reported as adjusted odds ratio [AOR] with 95% confidence intervals [CI]) with long-term fatigue.

RESULTS

Fatigue was present in 141 stroke survivors (55%) 4 years after stroke, with a mean FSS score of 5.2 ± 1.3. Having hypertension (AOR = 2.05, 95% CI: 1.05-3.99, P < .05), diabetes mellitus (AOR = 2.15, 95% CI: 1.09-4.25, P < .05), and arrhythmia (AOR = 3.01, 95% CI: 1.46-6.20, P < .01) at the time of stroke were associated with increased PSF at 4 years. Nonvascular risk factors including female sex (AOR = 1.99, 95% CI: 1.06-03.70, P < .05) and depression (AOR = 1.18, 95% CI: 1.01-1.39, P < .05) were related to PSF.

CONCLUSIONS

PSF was prevalent in the majority of survivors, with comorbid vascular factors significantly contributing to persistent fatigue. The implications of these findings are important as potentially modifiable factors can be targeted and treated from acute onset. Additional research examining PSF predictors in other populations and trialing targeted interventions to control predictors of PSF are warranted.
