Psychosocial Mediators between Socioeconomic Status and Dietary Restrictions among Patients Receiving Hemodialysis in Japan

Examining the Relationship between Dietary Intake, Socioeconomic Status, and Systolic Blood Pressure of Adults on Hemodialysis in Quito, Ecuador

Background

In Ecuador, the number of adults on hemodialysis (HD) continues to rise. Currently, the effect dietary habits and socioeconomic status (SES) have on blood pressure is not known for those on HD.

Objectives

The objectives of this study focused on adults on HD in Quito, Ecuador to 1) assess the relationship between dietary intake and SES; 2) compare dietary intake to the Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines; and 3) explore the relationship between dietary intake and systolic blood pressure.

Methods

This cross-sectional study was conducted at the dialysis center within Eugenio Espejo Specialties Hospital in Quito, Ecuador between May and June 2022 among 50 adults on HD. Three 24-h recalls were used to determine average dietary intake and the 25-item Instituto Nacional de Estadística y Censos-Stratification of SES was used to determine SES. Electrolytes and 2 blood pressure readings were collected. Qualitative narrative data analysis was performed to identify themes using NVivo v12. T-tests of independence, simple, and multiple linear regressions using age and sex as confounders were conducted using R and a P < 0.05 was deemed as statistically significant.

Results

On an average, 76% of participants consumed <25 kcal/kg body weight energy and 64% consumed <1 g protein/kg body weight. Participants consumed less energy and protein compared with the KDOQI guidelines (P < 0.05). Positive relationships were observed with potassium and blood pressure (β = 0.020, P < 0.05) and SES with energy, protein, and phosphorus (P < 0.05). Themes that were identified as contributing to dietary intake were limited knowledge, lack of consistency with dietary information, and limited appetite.

Conclusions

Findings from this study indicate that the focus should be on improving energy and protein intake for this population.

Influence of dialysis-related stigma on health-related indicators in Japanese patients undergoing hemodialysis

INTRODUCTION

Focusing on impacts to health-related indicators in older Japanese patients, this study analyzed both the direct influence of dialysis-related stigma and influences of its intersectionality with other stigmatized characteristics.

METHODS

Data were collected through a cross-sectional survey of 7461 outpatients in dialysis facilities. Other stigmatized characteristics include lower income, lower education, disabled activities of daily living, and diabetic end-stage renal disease (ESRD) as a cause for starting dialysis treatment.

RESULTS

The average rate of an "agree" response on dialysis-related stigma items was 18.2%. Dialysis-related stigma significantly influenced all three health-related indicators, including suspected depression, informal networks, and compliance with dietary therapy. In addition, each interaction between dialysis-related stigma and educational attainment, gender, and diabetic ESRD significantly influence one health-related indicator.

CONCLUSION

These results suggest that dialysis-related stigma has both a significant direct and synergic influence with other stigmatized characteristics on health-related indicators.

Discordance between hemodialysis patients' reports and their physicians' estimates of adherence to dietary restrictions in Japan

INTRODUCTION

This study examined the discordance between hemodialysis patients' reports and their physicians' estimates of dietary restriction adherence and related factors in Japan.

METHODS

In a cross-sectional survey of 6,644 outpatients, physicians who estimated higher and lower adherence than their patients' self-reported were categorized as overestimation and underestimation in terms of discordance, respectively. Possible factors included clinical indicators, patient characteristics related to negative stereotypes, and health beliefs related to statistical discrimination.

RESULTS

The concordance rate was .069 based on the weighted kappa coefficient. The coefficients of acceptable serum potassium, prevalence of diabetes, and self-efficacy on overestimates were .663 , -.126, and -.132, respectively. The coefficients of these factors on underestimates were -.589, .338, and .145, respectively. All these coefficients were significant.

CONCLUSIONS

The discordance may be high and is related to physicians' clinical data reliance, negative stereotypes about patient characteristics, and a lack of understanding of patients' health beliefs.

Factors affecting supportive needs in hemodialysis patients: A literature review

Background

Explaining the factors affecting supportive needs of patients under hemodialysis seems to be essential to supply their needs. Also, it can help healthcare providers to make favorite decisions about care planning to improve the patients' quality of life.

Objective

This study was conducted to determine the factors affecting supportive needs in hemodialysis patients using a literature review.

Methods

This literature review was carried out in PubMed, MEDLINE, SCOPUS, SID, Magiran, and Iranmedex. Data based were searched from 2000 to 2018 using the keywords of "Need", "Supportive Need", and "Hemodialysis". In a total of 239 full texts of published articles, 12 such relevant articles were selected.

Results

The finding showed that the factors affecting the supportive need of patients can be categorised into two: internal and external factors. Internal factors consist of patient-related factors, disease-related factors, and treatment-related factors. External factors consist of personal living circumstances, health system-related factors and socioeconomic factors.

Conclusion

By explaining the factors affecting supportive need in hemodialysis patients, it may help clinicians and researchers to identify the patients' need, developing an appropriate questionnaire, and implementing suitable intervention. As a result, it can improve their quality of life.

Illness Perceptions, Self-Care Management, and Clinical Outcomes According to Age-Group in Korean Hemodialysis Patients

Illness perception, formed in social-cultural contexts, is the driving force for health behavior. Age difference can affect health outcomes due to its association with socioeconomic status. The purpose of this study is to determine the relationship between illness perception, self-care management, and clinical outcomes according to the age group in hemodialysis patients. A cross-sectional study was conducted. Using the Brief Illness Perception Questionnaire (BIPQ) and Patient Activation Measure (PAM) 13, clinical outcomes, such as serum phosphorus, potassium, hemoglobin, and albumin were investigated in maintenance hemodialysis patients. Illness perception, self-care management, and clinical outcomes in 189 hemodialysis patients were different according to age group. Younger hemodialysis patients had the lowest illness perception and the highest serum phosphorus. Illness perception was associated with self-care management and clinical outcomes. After the adjusted age, the association between illness perception and self-care management and the association between illness perception and phosphorus were reduced, while the association between illness perception and potassium increased. Uncontrolled phosphorus in younger hemodialysis patients can increase the risk of cardiovascular complications and mortality. To improve self-care management and clinical outcomes in hemodialysis patients, reconstruction, or expansion of illness perception needs to be differentiated according to age group.
