title: [Protein-energy malnutrition. Diagnostic methods and epidemiology].
abstract: BACKGROUND
  Protein-calorie malnutrition (PCM) is highly prevalent among elderly persons living in the community (4%), hospitalized in acute care units or geriatric rehabilitation units (50%), or in long-term care facilities (30-40%). PCM is the first predictor of poor prognosis in the elderly.
  
  
  METHODS
  Parameters used to establish the diagnosis of PCM and identify its pathophysiology are both simple and inexpensive: body mass index, plasma albumin and CRP, arm circumference and skin fold thickness.
  
  
  CONCLUSIONS
  Because of its frequency and consequences on morbidity and mortality in the elderly, PCM is an important public health problem in industrialized countries.
