Description
Summary:•Obesity, based on body fat percentage, reduces the length of hospital stay•Higher hydration status lowers the chance of death in older adults•Abdominal obesity lowers the chance of death in older adults. The objective of this study was to assess the association between different anthropometric and body composition techniques for defining obesity status and to investigate their clinical implications in older hospitalized patients, both during their hospitalization and after discharge. This prospective study included patients aged 60 years and older. They were followed up for 18 months to assess mortality and length of hospital stay. Anthropometric measurements and body composition were evaluated, including Body Mass Index (BMI), waist circumference, waist-to-height ratio, percentage of body fat, total body water percentage, and muscle mass. These measurements are associated with prognosis and survival. A higher BMI, excessive body fat, higher total body water percentage, and abdominal obesity were associated with a lower risk of death (p
