Har koffein en omedelbar effekt på energiintaget? En systematisk litteraturöversikt Malin Foxing
Does caffeine have an immediate effect on energy intake? A systematic review.
Abstract
Syfte: Syftet med denna systematiska litteraturöversikt var att undersöka evidensen för huruvida koffein kan ha en omedelbar effekt på energiintaget hos vuxna ≥ 18 år.
Metod: Litteratursökningen genomfördes i databaserna Pubmed och Scopus den 21 mars 2023. Tillvägagångssättet för artikelurvalet var systematiskt och innefattade randomiserade kontrollerade humanstudier på en vuxen population. Artiklar som haft övervikt och/eller obesitas som specifikt inklusionskriterium exkluderades. Studierna skulle undersöka koffeininnehållande drycker och/eller koffein i kapsel- eller tablettform i kombination med dryck jämfört med placebo. Utfallsmåttet var det omedelbara energiintaget efter koffein- administration. Energiintaget skulle ha uppmätts vid efterterföljande ad libitum-måltid, senast tolv timmar efter intag av koffein. Studier som uppfyllde fastställda inklusions- och exklusionskriterier kvalitetsgranskades enligt SBU:s mall Bedömning av randomiserade studier (effekt av att tilldelas en intervention (ITT)). Resultatets tillförlitlighet bedömdes enligt GRADE, The Grading of Recommendations Assessment, Development and Evaluation.
Resultat: Litteratursökningen resulterade i 342 unika artiklar. Av dessa lästes 14 artiklar i fulltext, varav fem inkluderades i den systematiska översikten. Risken för bias bedömdes som måttlig i samtliga studier. Ingen signifikant effekt av koffein på omedelbart energiintag vid ad libitum-måltid kunde påvisas. Resultaten hos ingående studier var samstämmiga, men viss variation förekom. Resultatet bedömdes ha måttlig tillförlitlighet enligt GRADE.
Slutsats: Resultatet av denna systematiska litteraturöversikt visar på att koffein inte har någon omedelbar signifikant effekt på energiintaget. Tillförlitligheten till det sammanvägda resultatet bedömdes som måttlig (+++) enligt GRADE.

Other description
Aim: The purpose of this systematic literature review was to examine the evidence for whether cafffeine may have an immediate effect on energy intake in adults
≥ 18 years.
Methods: The literature search was performed in the databases Pubmed and Scopus, on mars 21 2023. The procedure for the article selection was performed systematically and included randomized controlled human trials in an adult population. Articles that had overweight and/or obesity as a specific inclusion criterion were excluded. The studies would examine caffeinated beverages and/or caffeine in form of a capsule or tablet in combination with beverages, compared to placebo. The outcome measure was immediate energy intake after caffeine administration. The energy intake would have been measured at the following ad libitum meal, a maximum of twelve hours after caffeine intake. Studies that met established inclusion- and exclusion criterias were reviewed in regards to quality using the SBU´s template Assessment of randomized studies (effect of being assigned an intervention (ITT)). The reliability of the result was assessed according to GRADE, The Grading of Recommendations Assessment, Development and Evaluation.
Results: The literature search resulted in 342 unique articles. Of these, 14 articles were red in full text, of which five were included in this systematic review. The risk of bias were assessed as moderate for all studies. No significant effect of caffeine on immeadiate energy intake at ad libitum meal were found. The results of the included studies were consistent, even though some variations were observed. The reliability of the result were assessed as moderate according to GRADE.
Conclusion: The result of this systematic literature review shows that caffeine does not have an immediate significant effect on energy intake. The reliability of the result were assessed as moderate (+++) according to GRADE.
