Estimating energy requirements in hospitalised underweight and obese patients requiring nutritional support: a survey of dietetic practice in the United Kingdom

摘要

BACKGROUND: Many methods are available to determine energy requirements, however, all have limitations, particularly when used for the obese. OBJECTIVES: The aim of this survey was to investigate current practice in the estimation of energy requirements in an underweight and obese hospitalised patient in a large cohort of UK dietitians. SUBJECT/METHODS: A cross-sectional anonymous online survey of UK registered dietitians was performed. RESULTS: A total of 672 responses were received. Underweight patient: prediction equations with adjustment for metabolic stress and physical activity were most commonly used (90%). The median estimated energy requirement was 2079 kcals/day. The estimated energy requirement using calorie per kilogram method was significantly lower compared with equations (P
