Malnutrition in hospitalized patients is a critical healthcare globally. It affects a patient’s quality of life, thereby increasing mortality and morbidity. In a hospital setting, where patients are admitted for a long term stay, infection rate increases and expenditure is also increased. The increase in malnutrition-related diseases in people with multiple comorbidities is a growing health concern, and it is strictly related to both the aging of the general population and the improvement in healthcare of note, this population group more often needs hospitalization. Between 20 and 50% of patients are present with malnutrition before hospital admission. Of note, 49% of malnourished patients that are hospitalized for more than a week maintain or face a deterioration of their previous nutritional status. Moreover, about a third of patients with a preserved nutritional status before hospital admission will develop malnutrition during hospital stay (Reziean et al, 2025). In the present study, fifty six patients were thus selected for nutritional assessment, but for anthropometry, it was possible to include only 50 patients, as 6 patients were bedridden and their weight and height measurements were not feasible. The values obtained for height and weight status in this study showed that the patients’ initial nutritional status was quite satisfactory, and compared fairly well with the ICMR (2010) values for reference man and woman and patients did not appear to be at a nutritional risk. Weight loss observed in 40% patients after 10-15 days of hospitalization was of a small magnitude and not significant (p=<0.05) but was a matter of concern, as it could possibly increase over a 3-6 month period (as stipulated by Malnutrition Universal Screening Tool or MUST), with continued hospitalization. Inappropriate nutrition as one of the contributory factors for this weight loss thus may be one of the causes that may need to be addressed, although iatrogenic malnutrition may be due to several factors. The average change in BMI over a 10-15 day showed that 58% of patients showed no change in BMI whereas 40% percent showed reduction in BMI which ranged from 0.1-3.9 (0.43- 16.18%) after 10-15 days, but the BMI being still in the normal range. This was as expected and in consonance with changes observed in body weight and a possible cause of concern. It was also seen from the study that in one patient, BMI had increased minimally by 0.38%. Several factors contribute to the worsening of nutritional status during hospitalization: illness-related loss of appetite, fasting for diagnostic procedures, drug-related side effects, diseases that compromise the regular functioning of the digestive system, and the poor management of patient nutrition. Nutritional anthropometry defined by Jelliffe (1989) and WHO (2023) involves “measurements of the variations of the physical dimensions and the gross composition of the human body at different age levels and degrees of nutrition.” Common measurements especially in the hospital setting include MUAC, height, weight and BMI. BMI indicates the weight status and MUAC indicates subcutaneous fat which shows nutritional status of a person.
