The Relationship Between Upper Arm Circumference and Phase Angle as a Marker of Quality of Life in Hemodialysis Patients

Introduction

Chronic Kidney Disease (CKD) is a condition that affects millions of people worldwide, and its progression to End-Stage Renal Disease (ESRD) often requires regular hemodialysis (HD) as a life-sustaining treatment. However, HD patients are at a higher risk of malnutrition due to various factors related to decreased kidney function. Malnutrition can have a significant impact on the quality of life and life expectancy of HD patients. Therefore, it is essential to assess the nutritional status of these patients accurately and effectively.

The Importance of Nutritional Status Assessment in Hemodialysis Patients

Nutritional status assessment is crucial in HD patients as malnutrition can lead to various complications, including muscle wasting, weakness, and increased risk of infections. The measurement of upper arm circumference (LLA) is a simple, inexpensive, and non-invasive method to assess nutritional status. However, LLA alone may not provide a comprehensive picture of nutritional status, as it does not account for the body's cellular composition.

Bioelectrical Impedance Analysis (BIA) and Phase Angle (PHA)

Bioelectrical Impedance Analysis (BIA) is a non-invasive technique that measures the body's electrical resistance to a small electrical current. BIA can provide information about the body's cellular composition, including fat mass, lean mass, and water content. Phase Angle (PHA) is a parameter derived from BIA that has been shown to have a strong correlation with quality of life and mortality. PHA is a measure of the body's cellular integrity and is influenced by factors such as muscle mass, body fat, and hydration status.

The Relationship Between Upper Arm Circumference and Phase Angle

This study aimed to investigate the relationship between upper arm circumference (LLA) and phase angle (PHA) as a marker of quality of life in hemodialysis patients. The study was conducted on 52 HD patients who underwent regular hemodialysis twice a week. The patients' nutritional status was assessed using LLA and BIA examination after a hemodialysis session.

Results

The results of the study showed that 15 (28.85%) of the 52 patients experienced malnutrition. There was a significant relationship between LLA and PHA (r = 0.666; p < 0.0001). This finding suggests that LLA can be used as a predictor of PHA in HD patients.

Conclusion

The study's findings suggest that upper arm circumference (LLA) is a significant predictor of phase angle (PHA) in hemodialysis patients. Considering that malnutrition is related to a decrease in quality of life, LLA measurements are recommended regularly in HD patients to evaluate nutritional status. The measurement of LLA and PHA can complement each other in providing information about the nutritional status and quality of life of HD patients.

The Importance of Early Detection of Malnutrition

Malnutrition in HD patients can have a serious impact on the quality of life and increase the risk of death. Early detection and timely intervention are very important to prevent complications. Medical personnel need to increase awareness about the importance of monitoring nutritional status in HD patients, including through the measurement of LLA and PHA.

Monitoring Policy

There is a need for policies that support routine monitoring of HD patient nutritional status, including the measurement of LLA and PHA. By understanding the relationship between LLA and PHA, we can improve the prevention and handling strategies of malnutrition in HD patients, so as to improve the quality of their lives and life expectancy.

Recommendations

Based on the study's findings, the following recommendations are made:

Regular measurement of upper arm circumference (LLA): LLA measurements should be taken regularly in HD patients to evaluate nutritional status.
Bioelectrical Impedance Analysis (BIA) examination: BIA examination should be performed regularly in HD patients to assess cellular composition and phase angle (PHA).
Increased awareness of medical personnel: Medical personnel need to increase awareness about the importance of monitoring nutritional status in HD patients, including through the measurement of LLA and PHA.
Monitoring policy: There is a need for policies that support routine monitoring of HD patient nutritional status, including the measurement of LLA and PHA.

By implementing these recommendations, we can improve the prevention and handling strategies of malnutrition in HD patients, so as to improve the quality of their lives and life expectancy.
