BMI Misclassifies Over a Third of Adults Study Finds Body Fat Errors - grandgoldman.com

Et stort nyt studie offentliggjort i april 2026 har vist, at Body Mass Index (BMI)—en af de mest anvendte målemetoder i klinisk medicin og folkesundhed—fejlklassificerer sundhedstilstanden for mere end en tredjedel af voksne. Ved at sammenligne BMI-baserede klassifikationer med præcise kropsfedtmålinger opnået via dual-energy røntgenabsorptiometri (DXA)-scanninger, afslørede forskerne systematiske fejl, der har dybtgående konsekvenser for klinisk praksis.

Videnskaben bag studiet

DXA-scanning giver en direkte, yderst præcis måling af fedtvæv, muskelmasse og knogletæthed—information som BMI, et simpelt forhold mellem vægt og højde, ikke kan indfange. Studiet viste, at en betydelig andel af personer klassificeret som "normalvægtige" ifølge BMI faktisk havde overskydende kropsfedt, mens andre klassificeret som "overvægtige" havde sunde fedtniveauer og høj muskelmasse. Disse fejl forekommer på tværs af alder, køn og etniske grupper.

Hvem bliver mest påvirket?

Ældre voksne, især kvinder, bliver uforholdsmæssigt ofte fejlklassificeret, fordi aldersrelateret muskeltab reducerer vægten, selv mens fedtet ophobes. Atleter og personer med høj muskelmasse registreres ofte som overvægtige eller svært overvægtige på BMI-skalaen, på trods af at de har en lav og sund kropsfedtprocent. Forskerne fandt også systematiske race- og etniske skævheder i BMI-grænseværdierne, som i høj grad var baseret på studier af befolkninger med europæisk afstamning.

Kliniske og politiske implikationer

Resultaterne udfordrer sundhedsvæsener til at bevæge sig væk fra BMI som et primært screeningsredskab. Forskerne anbefaler at integrere taljemål, kropssammensætningsanalyse og metaboliske biomarkører i rutinemæssige vurderinger for at opnå et mere præcist billede af individuel sundhedsrisiko. Forsikringsbaserede BMI-grænser – brugt til at bestemme dækning for vægttabsbehandlinger – kan også have behov for at blive revideret.

Hvad patienter bør gøre

Personer, der er bekymrede for deres metaboliske helbred, opfordres til at anmode om en mere omfattende kardiometabolisk vurdering hos deres sundhedsudbydere, herunder fastende glukose, lipidprofiler og blodtryksmålinger. I sidste ende understreger undersøgelsen budskabet om, at sundhed ikke kan reduceres til et enkelt tal – og at personlig, evidensbaseret evaluering er afgørende for præcis diagnose og effektiv forebyggende behandling.
