Prevalence of malnutrition in hospitalised children: retrospective study in a Spanish tertiary-level hospital.

Objective: To analyse the prevalence of malnutrition among paediatric patients at the time of hospital admission throughout a calendar year in a tertiary-level hospital and to identify those patients and/or groups of pathologies with a higher risk of malnutrition.

Design: Observational (retrospective evaluation of nutrition status).

Setting: Navarra Hospital Complex, Pamplona, Spain.

Participants: A total of 852 patients hospitalised in 2013 in a Spanish tertiary-level paediatric hospital (462 males and 390 females).

Main Outcome Measures: Sex, age, body mass index at the moment of admission and days of hospitalisation and diagnosis codified according to the International Classification of Diseases were registered.

Results: The prevalence of malnutrition patients registered at the moment of admission was 8.2%. Diseases of the nervous system (22.9%), together with diseases of the respiratory system (22.9%), infectious diseases (18.6%), congenital malformations (11.4%) and diseases of the genitourinary system (8.6%) account for 84.4% of the cases with malnutrition.

Conclusions: The overall prevalence rate for malnutrition in paediatric patients at the moment of admission in our hospital was 8.2%, being a figure similar to those published in occidental countries. It should be mandatory to accomplish an initial screening and follow-up during hospitalisation of younger patients and those suffering from diseases of the nervous and/or respiratory system and, especially, from congenital diseases.
