Summary
Improving dietary adherence in hemodialysis patients requires interventions that enhance self-efficacy and perceived benefits while reducing perceived barriers. This study explored the links between dietary knowledge, health beliefs, and practice in this population.
Area of Science:
- Nephrology
- Public Health
- Health Psychology
Background:
- Hemodialysis patients often struggle with dietary adherence, impacting their health outcomes.
- Understanding the factors influencing dietary practices is crucial for developing effective interventions.
Purpose of the Study:
- To investigate the correlation between dietary knowledge, health belief, and practice in hemodialysis patients using structural equation modeling.
- To identify key determinants of dietary practice among individuals undergoing hemodialysis.
Main Methods:
- A multicenter, cross-sectional study involving 558 hemodialysis patients.
- Data collected using validated questionnaires on dietary knowledge, practice, and health beliefs (perceived susceptibility, severity, benefits, barriers, self-efficacy).
- Structural equation modeling and multiple linear regression analyses were employed.
Main Results:
- Female gender, higher perceived benefits, and higher self-efficacy were associated with better dietary practice.
- Lower perceived susceptibility and lower perceived barriers also correlated with improved dietary practice.
- Dietary knowledge significantly influenced perceived severity, perceived benefits, and self-efficacy.
Conclusions:
- Dietary interventions should prioritize enhancing self-efficacy and perceived benefits.
- Minimizing perceived barriers is essential for improving dietary adherence in hemodialysis patients.
- Targeted educational strategies can positively impact dietary practices and health outcomes.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

1.7K
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
