Nutritional Risk Screening in Hospitalized Adults Using the Malnutrition Universal Screening Tool at a Tertiary Care Hospital in South India

Abstract

Background and objectives Malnutrition is still widely prevalent in India. Various nutritional screening tools have been developed to screen for nutritional risk status but no one tool is considered the best. The Malnutrition Universal Screening Tool (MUST) is accepted by the European Society for Clinical Nutrition and Metabolism and validated for use in hospitalized adults. Hence, it was used in this study to estimate the prevalence of malnutrition in hospitalized adults and its association with socioeconomic inequality. Methods A sample of randomly selected 358 ambulatory hospitalized patients above 18 years of age was used in the study. Data pertaining to demography, socioeconomic status, medical history, and MUST were collected using a structured questionnaire. The height and weight of the patients were measured, and their BMI was determined. The patients were classified into five socioeconomic classes and their MUST scores were determined. Results Statistically significant (P < 0.05) increasing trend was observed in the height, weight, and BMI of patients with increasing socioeconomic status. Diabetes mellitus (39%) followed by hypertension (30%) were the predominant comorbid conditions. According to MUST, the overall prevalence of medium and high risk of malnutrition was 11% and 24%, respectively, and the socioeconomic class that was most impacted was Class 4 (1,130-2,259 INR per capita monthly income). Interpretation and conclusions Socioeconomic status influences the prevalence of malnutrition, comorbid conditions, and the anthropometric measurements of admitted patients. The prevalence of nutritional risk status irrespective of sex was found to be 34.91% (24.3% in males and 10.61% in women) in the study.
