Nutritional risk in pediatrics by StrongKids: a systematic review

The nutritional risk in hospitalized children and adolescents is a frequent and under-diagnosed reality. There is still no consensus regarding the best nutritional screening method in pediatrics, with StrongKids being one of the existing proposals. A systematic review was performed to evaluate the scientific evidence about StrongKids, with emphasis on the world frequency of nutritional risk, associations of interest in health, validation and reproducibility studies. Databases Pubmed, Lilacs, Scielo, ScienceDirect, Web of Science, Scopus and Cochrane Library were searched, using keyword “StrongKids,” without limit on the year of publication, in English, Spanish, and Portuguese. From 125 papers initially identified, 22 original were included in analysis. The sample size ranged from 43 to 2874, with a maximum of 44 hospitals. The frequency of nutritional risk (medium or high) ranged from 35.7 to 100%. The nutritional risk was mainly associated with acute and/or chronic malnutrition already installed, lower anthropometric indexes and longer length of hospital stay. The method presented satisfactory inter-rater and intra-rater agreements and was validated in the three studies performed with this proposal. The prevalence of nutritional risk in hospitalized children and adolescents is high. StrongKids is a valid, easy-to-use, and reproducible method, with significant associations of interest in health.
