Determinants of Resting Energy Expenditure in Very Old Nursing Home Residents

Objectives This study aimed to measure resting energy expenditure (REE) in institutionalized old persons and to determine factors possibly related to change in REE as a basis for estimating energy requirements. Design and Settings A monocentric cross-sectional study was conducted. Statistical approaches were conducted to determine independent factors associated with REE. Various published predictive equations of REE were compared to our population. Participants 72 residents of a nursing home, mostly women (80.5%) aged 87.4±6.6 years were included. Measurements REE (indirect calorimetry), body composition (bio-impedance analysis), biological and anthropometric data were collected. Results Mean REE was 1006±181 kcal/d and was higher in men than in (1227±195 vs. 953±131 kcal/d, p 25 mg/l). Significant differences (p
