Does Depression and Anxiety Mediate the Relation between Limited Health Literacy and Diet Non-Adherence?

Online screening for excessive daytime sleepiness: a feasibility study

Purpose

Excessive daytime sleepiness (EDS) can have a significant impact on health and quality of life but may remain undiagnosed due to low awareness and underestimation of the clinical impact of the symptoms. An online screening tool supported by media campaigns might increase awareness and help detect undiagnosed cases of EDS and narcolepsy. The aim of this study was to develop an online screening method, along with a media campaign focusing on EDS, and evaluate its feasibility.

Methods

Online screening supported by a media campaign targeting young and middle-aged adults (18-45 years old) were developed and implemented over a period of 1 year starting from November 2022. The Epworth Sleepiness Scale was used to identify EDS, and the Swiss Narcolepsy Scale was used to identify narcolepsy. In addition, the data on sociodemographic characteristics, selected sleep and health indicators and lifestyle behaviors were collected to indicate the etiology of the EDS. Feasibility, e.g., implementation and practicality, was assessed by the response rate, response to the promotion strategy, time spent on the tool, sample characteristics, and the prevalence of identified EDS and narcolepsy cases.

Results

A total of 2,390 people opened the screening link; 568 of them completed the online screening (23.8%), and most of them (n = 437, 76.9%) left their contact data to receive feedback. We identified 171 (30.1%) respondents at risk of EDS and 61 (10.7%) at risk of narcolepsy. The mean time of the screening was 15 min.

Conclusion

An online screening tool supported with a campaign seems to be a feasible way to increase awareness about EDS and prevent delayed detection of EDS cases.

Depression mediates the association between health literacy and health-related quality of life after myocardial infarction

Introduction

So far, health literacy (HL) and its related factors in patients with acute myocardial infarction received little attention. Thus, the objective of this study was to investigate the associations between the different dimensions of HL and disease-specific health-related quality of life (HRQOL), and factors that may affect these relations in patients after acute myocardial infarction (AMI).

Methods

All survivors of AMI between June 2020 and September 2021, from the Myocardial Infarction Registry Augsburg (n=882) received a postal questionnaire on HL [Health Literacy Questionnaire (HLQ)], HRQOL (MacNew Heart Disease HRQOL questionnaire) and depression (Patient Health Questionnaire). From the 592 respondents, 546 could be included in the analysis. Multivariable linear regression models were performed to investigate the associations between the nine subscales of the HLQ and the total score and three subscales of the MacNew questionnaire. A mediation analysis was performed to estimate direct and indirect effects of HL on HRQOL taking into account the mediating effect of depression.

Results

In the sample of 546 patients (72.5% male, mean age 68.5 ± 12.2 years), patients with poor education showed significantly lower HLQ scores. Significant associations between the subscales of the HLQ and the MacNew were found, which remained significant after adjustment for sociodemographic variables with few exceptions. More than 50% of the association between HL and HRQOL was mediated by depression in seven HLQ subscales and a complete mediating effect was found for the HLQ subscales 'Actively managing my health' and 'Appraisal of health information'.

Discussion

Depression mediates the associations between HL and disease-specific HRQOL in patients with myocardial infarction.

Anxiety and depression in geriatric hemodialysis patients: factors that influence the border of diseases

INTRODUCTION

The two main psychological issues that people with end-stage renal disease (ESRD) experience are depression and anxiety. We conducted this study to determine both the prevalence of depression and anxiety, and the factors associated with them, among hemodialysis patients.

METHODS

Patients aged 18 years or older, who had received hemodialysis in a hemodialysis center in Elbasan, for at least 3 months were included in this study. Beck Anxiety Inventory and Beck Depression Inventory Instruments were used to assess hemodialysis patients levels of depression and anxiety.

RESULTS

Overall, 107 hemodialysis patients (men 65.4%) with a mean age of 57 ± 8.9 years were enrolled in the study. The prevalence of anxiety and depression resulted to be 85.98, and 84.11%, respectively. We found a significant difference in depression and anxiety scores in patients age groups of 61-70 years old (OR = 1.8; 95% CI [0.7-3.7]; p = 0.041), in non-smoking patients (OR 3.4; 95% CI [1.09-8.2]; p = 0.04), in diabetic patients (OR 3.4; 95% CI [1.09-8.2]; p = 0.04), and in patients with a time in dialysis of 6-10 years and >11 years, respectively, (OR 3.4; 95% [1.5-9.0]; p = 0.01), (OR1.3; 95% CI [0.4-3.6]; p = 0.04).

CONCLUSION

Our study shows that the prevalence of mental disorders (depression and anxiety) is high among patients with ESRD on maintenance hemodialysis. We recommend a routine screening and referral to psychological health specialists to evaluate the mental health disorders among hemodialysis patients with the primary aim of improving their quality of life.

Factors affecting the levels of anxiety and depression among patients with end-stage renal disease undergoing hemodialysis

BACK GROUND

Hemodialysis (HD) is a lifesaving procedure required for many patients with end stage renal disease (ESRD) who are not able to undergo a kidney transplant. However, HD could cause anxiety and depression for those patients. This study aimed to assess the levels of anxiety and depressive symptoms and find out the predictors affecting them.

MATERIALS AND METHODS

A cross-sectional, descriptive correlational design was adopted on a sample of 230 patients who received HD. Patients answered the Hospital Anxiety and Depression Scale along with demographic and clinical variables.

RESULTS

The study found that patients with ESRD undergoing HD had a high level of anxiety (mean = 10.59 SD = 2.78) and depression (mean = 10.86 SD = 2.49). There were significant differences in anxiety and depressive symptoms in regard to comorbidity, vascular access type, fatigue, fear, and financial status. Predictors of anxiety and depressive symptoms were: creatinine level, fatigue level, HD duration, number of dialysis sessions, blood urea nitrogen level, and age.

CONCLUSIONS

Anxiety and depression are under-diagnosed in patients with ESRD undergoing HD in Jordan. Screening and referral to psychological health specialists are needed.

The Relationship Between Health Literacy Level and Neuropathic Pain Level in Patients With Diabetic Neuropathy

Background This study aimed to analyze the current situation of health literacy (HL), neuropathic pain, and Neuropathic Pain Impact on Quality of Life (NePIQoL) questionnaire in patients with diabetic neuropathy (DN). Methodology This study was conducted among 60 patients with diabetic peripheral distal neuropathy on electroneuromyography (ENMG) and 47 patients without diabetic peripheral distal neuropathy on ENMG. The Turkish version of the European Health Literacy Scale (EHLS-TR) for HL levels, Visual Analog Scale (VAS) and Douleur Neuropathique 4 Questions (DN4) for pain level, and NePIQoL for health-related quality of life were used in participants. Results A total of 107 type 2 diabetes mellitus patients were included in the study with a mean age of 57.12 ± 4.12 years. The EHLS-TR significantly decreased in the DN group compared to the control group (p = 0.004). There was a significant difference between the two groups in the EHLS-TR classification (p = 0.024). Glycosylated hemoglobin (HbA1c), VAS, and DN4 values were found to be significantly higher in the DN group compared to the control group (p = 0.001). While there was a negative correlation between EHLS-TR scores and DN4 and HbA1c in the DN group, a positive correlation was found between EHLS-TR and NePIQoL. Conclusions HL has an effect on HbA1c, neuropathic pain level, and quality of life in DN patients. By increasing the level of HL, glycemic control can be achieved in this patient population, while the level of neuropathic pain decreases and the quality of life increases.

Correlation between health literacy and health‐related quality of life in patients with diabetic peripheral neuropathy: The mediating role of self‐management

AIM

The aims of the study were to analyse the current situation of health literacy (HL), self-management and health-related quality of life (HRQOL) in patients with diabetic peripheral neuropathy (DPN), to explore the correlation between the three and to verify the mediating role of self-management in HL and HRQOL.

DESIGN

A cross-sectional survey.

METHODS

The convenience sampling method was used to select 401 DPN patients attending the First Hospital of Jinzhou Medical University in Liaoning Province, China, from December 2020 to December 2021 as the study population. The research instrument included socio-demographic characteristics questionnaire, Health Literacy Management Scale (HeLMS), Summary of Diabetes Self-Care Activities (SDSCA) and Short-Form 12-item Health Survey (SF-12). SPSS 25.0 was applied to the data for descriptive analysis, Pearson correlation analysis and stratified multiple regression analysis. Mediating effects were tested using SPSS PROCESS macro 4.0 software.

RESULTS

HL and self-management of DPN patients correlated positively with HRQOL. The mediation role of self-management was significant in the relationship between HL and physical and mental HRQOL (physical component summary: β = 0.26, P < 0.01; mental component summary: β = 0.18, P < 0.01), with mediating effects accounting for 35.62% and 34.62% of the total effect.

CONCLUSIONS

There was a positive correlation between HL, self-management and HRQOL in patients with DPN. Self-management plays a partially mediating role in the relationship between HL and HRQOL in DPN patients. It means that HRQOL in this population can be improved by increasing HL and thus self-management in DPN patients.

Low Health Literacy Is Associated with Poorer Physical and Mental Health-Related Quality of Life in Dialysed Patients

Health-related quality of life (HRQoL) is an important health indicator in chronic diseases like kidney diseases. Health literacy (HL) may strongly affect HRQoL, but evidence is scarce. Therefore, we assessed the associations of HL with HRQoL in dialysed patients. We performed a cross-sectional study in 20 dialysis clinics across Slovakia (n = 542 patients, mean age = 63.6 years, males = 60.7%). We assessed the association of categorised HL (low, moderate, high) with the SF36 physical component score (PCS) and mental component score (MCS) using generalised linear models adjusted for age, gender, education, and comorbidity (Charlson Comorbidity Index, CCI). We found significant associations of HL with PCS and MCS in dialysed patients, adjusted for age, gender, education, and CCI. Low-HL patients had a lower PCS (B = -3.27, 95%-confidence interval, CI: -5.76/-0.79) and MCS (B = -6.05, 95%-CI: -8.82/-3.29) than high-HL patients. Moderate-HL patients had a lower MCS (B = -4.26, 95%-CI: -6.83/-1.69) than high-HL patients. HL is associated with physical and mental HRQoL; this indicates that dialysed patients with lower HL deserve specific attention and tailored care to have their HRQoL increased.

The Associations of Suspected COVID-19 Symptoms with Anxiety and Depression as Modified by Hemodialysis Dietary Knowledge: A Multi-Dialysis Center Study

During the COVID-19 pandemic, it is essential to evaluate hemodialysis patients’ dietary knowledge, especially among those with COVID-19 related symptoms, in order to identify appropriate strategies in managing their mental health. The study’s purposes were to test the psychometric properties of the hemodialysis dietary knowledge (HDK) scale, and to investigate the modifying impact of HDK on the associations of suspected COVID-19 symptoms (S-COVID-19-S) with anxiety and depression among hemodialysis patients. A cross-sectional study was conducted from July 2020 to March 2021 at eight hospitals across Vietnam. Data of 875 hemodialysis patients were analyzed, including socio-demographic, anxiety (the generalized anxiety disorder scale, GAD-7), depression (the patient health questionnaire, PHQ-9), S-COVID-19-S, HDK, health literacy, and digital healthy diet literacy. Confirmatory factor analysis (CFA) and logistic regression models were used to analyze the data. The HDK scale demonstrates the satisfactory construct validity with good model fit (Goodness of Fit Index, GFI = 0.96; Adjusted Goodness of Fit Index, AGFI = 0.90; Standardized Root Mean Square Residual, SRMR = 0.05; Root Mean Square Error of Approximation, RMSEA = 0.09; Normed Fit Index, NFI = 0.96; Comparative Fit Index, CFI = 0.96, and Parsimony goodness of Fit Index, PGFI = 0.43), criterion validity (as correlated with HL (r = 0.22, p < 0.01) and DDL (r = 0.19, p < 0.01), and reliability (Cronbach alpha = 0.70)). In the multivariate analysis, S-COVID-19-S was associated with a higher likelihood of anxiety (odds ratio, OR, 20.76; 95% confidence interval, 95%CI, 8.85, 48.70; p < 0.001) and depression (OR, 12.95; 95%CI, 6.67, 25.14, p < 0.001). A higher HDK score was associated with a lower likelihood of anxiety (OR, 0.70; 95%CI, 0.64, 0.77; p < 0.001) and depression (OR, 0.72; 95%CI, 0.66, 0.79; p < 0.001). In the interaction analysis, the negative impacts of S-COVID-19-S on anxiety and depression were mitigated by higher HDK scores (p < 0.001). In conclusion, HDK is a valid and reliable tool to measure dietary knowledge in hemodialysis patients. Higher HDK scores potentially protect patients with S-COVID-19-S from anxiety and depression during the pandemic.

Health Literacy and Change in Health-Related Quality of Life in Dialysed Patients

Health-related quality of life (HRQoL) is likely to deteriorate with the progression of chronic kidney disease (CKD). This change may be worsened by low health literacy (HL). We performed a longitudinal study at over 20 dialysis clinics in Slovakia (n = 413; mean age = 64.8 years; males = 58.4%). We assessed the association of three HL groups with a change in HRQoL over two years using binary logistic regression adjusted for type of vascular access, dialysis effectiveness, comorbidity, age and gender. We found that patients with low HL had poorer HRQoL at baseline in comparison to high-HL patients. We did not find significant associations of lower HL with the deterioration of mental or physical HRQoL after two years. In the adjusted model, patients with lower HL were not more likely to have deteriorated physical (low-HL patients: odds ratio/95% confidence interval: 0.99/0.53–1.84; moderate-HL patients: 0.97/0.55–1.73) or mental HRQoL (low-HL patients: 1.00/0.53–1.87; moderate-HL patients: 0.95/0.53–1.70) in comparison to high-HL patients. The HRQoL of lower-HL patients is worse at baseline but develops similarly to that of high-HL patients during dialysis treatment. Their relative HRQoL, thus, does not worsen further, but it does not improve either. Tailoring care to their needs may help to decrease the burden of low HL in dialysed patients.
