The objectives of the present study are: 1) to characterize the energy-protein intake of the elderly during hospitalization; 2) to verify the influence of energy-protein intake during hospitalization on muscular (i.e., cross-sectional area of the rectus femoris and vastus lateralis muscles, muscle strength, functionality and level of independence) and clinical (i.e., length of hospital stay, hospital readmission and mortality) at the time of hospital discharge, 2 and 6 months after hospital discharge and; 3) to verify whether energy-protein intake during hospitalization is a significant predictor of loss of function and muscle mass, length of hospital stay, hospital readmission rate and mortality.

RECRUITINGVastus Lateralis Muscle Cross-sectional Area
Vastus Lateralis Muscle Cross-sectional Area will be assessed through ultrasound
Time frame: From date of admission until the date of medical discharge. Up to 30 days.
Handgrip strength
Strength will be evaluated using handgrip strength test
Time frame: From date of admission until the date of medical discharge. Up to 30 days.
Muscle function
Muscle function evaluated trough battery of test
Time frame: From date of admission until the date of medical discharge. Up to 30 days.
Functional independence
Functional independence will be assessed using Barthel Index. The scores range from 0 to 100. A score of 100 means the individual is fully independent, while lower scores indicate increasing levels of dependence.
Time frame: From date of admission until the date of medical discharge. Up to 30 days.
Length of hospital stay
Length of hospital stay will be the time (in days) until medical discharge.
Time frame: From date of admission until the date of medical discharge. Up to 30 days.
Mortality
Mortality rate in percent
Time frame: From date of admission until the date of medical discharge. Up to 30 days.
Hospital readmission post-medical discharge
Hospital readmission post-medical discharge will be the number of times that he is admitted in the hospital post-medical discharge.
Time frame: 1- and 2- months post-medical discharge
