body mass index and early PN-led support
Description
Data from a nationwide perspective observational study conducted between September and December 2014 were analyzed. A total of 379 patients with AGI were included and categorized into different BMI groups.Collected data included general demographics, primary diagnosis, Acute Physiology and Chronic Health Evaluation (APACHE II) score, AGI grade, total energy intake over a 72-hour period (TEI-72h), and 28-day mortality.For individuals with a BMI < 25 kg/m², actual body weight (ABW) was used to determine energy requirements. Moreover, for those with a BMI ≥ 25 kg/m², the reference (adjusted) body weight was replaced with the ideal body weight (IBW). The IBW was calculated by subtracting 100 (for males) or 106 (for females) from 0.9 multiplied by the height in centimeters. Additionally, when calculating energy requirements, it was considered to include 20% of the excess weight (the difference between the ABW and IBW) in addition to the IBW.
