Mer än 60 % av den europeiska vuxna befolkningen anses vara överviktiga (Body Mass Index (BMI) 25-29.9 kg/m2) eller obesa (BMI ≥ 30 kg/m2). Det är välkänt att högre BMI i medelåldern är förknippat med negativa hälsoeffekter och högre dödlighet. Därför rekommenderas vuxna (oavsett ålder) att sträva efter ett BMI mellan 18.5 och 24.9 kg/m2. Det finns dock ett omvänt samband i hög ålder där samband mellan högre BMI och bättre hälsa och högre överlevnad har påvisats. Det omvända sambandet kallas för fetma paradox och väcker frågan om de nuvarande BMI rekommendationerna gäller äldre människor.

Utifrån longitudinella befolkningsbaserade studier som har sitt ursprung från svenska Tvillingregistret där det finns uppgifter om BMI från tidig vuxen ålder till slutet av livet studerar Anna Dahl Aslan faktorer som påverkar att man utvecklar fetma och hur fetma och förändringar i fetma relaterar till förändringar i hälsa och överlevnad. 

Några av Anna Dahl Aslans viktigaste fynd är att hon har kartlagt hur BMI förändras på populations nivå från tidig vuxen ålder till ålderdomen och död. Både män och kvinnors BMI ökar upp till 65-års ålder och där efter avstannar ökningen för män medan kvinnor fortsätter att öka lite i vikt, men med betoning på lite. Vid 80-års ålder börjar både män och kvinnor att gå ner markant i vikt. Faktorer som är kopplade till förändring i BMI före 65 års ålder, som genetiska markörer och vissa sjukdomar, är ofta inte kopplat till förändringar i BMI senare i livet eller så finns det ett omvänt samband. 

Anna Dahl Aslan är engagerad i flera nationella och internationella forskningssamarbeten, bl.a. 

the Swedish Adoption/Twin Study of Aging (SATSA)

IGEMS; the consortium on Interplay of Genes and Environment across Multiple Studies

The National E-infrastructure for Aging Research (NEAR)
