Abstract
Background: Older adults represent a substantial portion of the population in India. Chronic kidney disease (CKD) is one of the major noncommunicable diseases in India. Older adults are one of the most vulnerable groups that suffer from CKD. The prognosis of the CKD often worsens with chronic protein-energy wasting (PEW). Thus, to address the imbalances of the amino acid and suboptimal intake of nutrients in older adults, the impact of oral nutritional supplements (ONS) was assessed in the study.
Methods and Materials: A total of 41 samples were selected based on the inclusion and exclusion criteria. Several nutritional, biochemical, haematological, and renovascular parameters were assessed during the initiation and at the end of 30 days of the study.
Results: The results revealed that calorie and protein intake have improved in the participants who received the ONS. The positive impacts were also observed in the biochemical, haematological, and renovascular parameters.
Conclusion: It can be concluded that a controlled intervention under the guidance of a clinical dietitian can be useful in the management of CKD, especially for older adults.
