Har intag av fet fisk effekt på kognitiv funktion hos barn under tio år?

En systematisk översiktsartikel

Does the intake of oily fish have an effect on cognitive function in children under ten years of age? – A systematic review article

Abstract
Syfte: Syftet med denna systematiska översiktsartikel var att undersöka det vetenskapliga underlaget för om intag av fet fisk har effekt på kognitiv funktion hos barn under tio år. Metod: Sökningar gjordes i databaserna PubMed och Scopus efter randomiserade kontrollerade studier. Inkluderad population var barn i åldrarna noll till tio år utan diagnostiserad sjukdom eller funktionsnedsättning. Interventionen var fet fisk. Utfallsmåttet var kognitiv funktion mätt med kognitionstestet Wechsler Preschool and Primary Scales of Intelligence, third edition (WPPSI-III). Studier som var skrivna på annat språk än engelska eller svenska exkluderades. Även studier där interventionen var tillskott av omega-3-fettsyror, fiskolja eller fiskmjöl exkluderades samt djurstudier. Slutsökning gjordes 25:e januari 2022 med sökorden “fishes”, “cognition”, “child”, “child, preschool”, “cognitive” och “fish”. Detta resulterade i 63 unika sökresultat varav fyra artiklar som lästes i fulltext. Av dessa inkluderades två studier som ligger till underlag för denna översikt. Artiklarna granskades med granskningsmall för att bedöma risk för bias, framtagen av Statens beredning för medicinsk och social utvärdering (SBU). Tillförlitlighet bedömdes enligt Grading of Recommendations, Assessment, Development and Evaluations (GRADE) för utfallsmåttet kognitiv funktion mätt med WPPSI-III. Resultat: Risken för bias bedömdes låg respektive måttlig för de inkluderade studierna. Resultatet visade samstämmigt att intag av fet fisk inte har effekt på kognitiv funktion mätt med WPPSI-III hos barn under tio år. Slutsats: Enligt GRADE finns det en måttlig tillförlitlighet (+++) att intag av fet fisk inte har effekt på kognitiv funktion hos barn under tio år.

Does the intake of oily fish have an effect on cognitive function in children under ten years of age? – A systematic review article. Abstract: Aim: The aim of this systematic review article was to investigate the scientific basis for whether intake of fatty fish has an effect on cognitive function in children under ten years of age. Methods: Searches were conducted in the databases PubMed and Scopus for randomized controlled trials. The included population was children aged zero to ten years without a diagnosed disease or disability. The intervention was oily fish. The outcome measure was cognitive function measured with the cognition test Wechsler Preschool and Primary Scales of Intelligence, third edition (WPPSI-III). Studies written in a language other than English or Swedish were excluded. Studies in which the intervention was supplement with omega-3 fatty acids, fish oil or fishmeal were also excluded, as well as animal studies. Final search was conducted on January 25, 2022 with the keywords "fishes", "cognition", "child", "child, preschool", "cognitive" and "fish". This resulted in 63 unique search results, four of which were read in full text. Of these, two studies were included and form the basis for this systematic review. The articles were reviewed with a review template to assess the risk of bias designed by the Swedish Agency for Health Technology Assessment and Assessment of Social Services (SBU). Reliability was assessed according to Grading of Recommendations, Assessment, Development and Evaluations (GRADE) for the outcome measure cognitive function measured with WPPSI-III. Results: The risk of bias was assessed as low respectively moderate for the included studies. The results consistently showed that the intake of oily fish does not have an effect on cognitive function measured with WPPSI-III in children under ten years of age. Conclusion: According to GRADE, there is a moderate certainty (+++) that the intake of oily fish does not have an effect on cognitive function in children under ten years.
