Om mig

Min forskning på Institutionen för försäkringsmedicine handlar om
konsekvenser av lång sjukfrånvaro i termer av hälsa, förtidspension och
dödlighet samt riskfaktorer för sjukfrånvaro. Jag jobbar med data från
det Svenska tvillingregistret, andra nationella register samt
frågeformulär.
Jag jobbar även på Gymnastik- och idrottshögskoaln där min
forskningsfokus är på fysisk aktivitet och stillasittande bland
skolungdomar och hur det är relaterat till hjärnhälsa d.v.s. kognition och
psykisk hälsa. Projektet kallas Hjärnhälsa i skolan och innehåller både
tvärssnittsstudier samt försök i labbmiljö.
Min doktorsavhandling handlade om hur man kan behandla deprimerade människor
med fysisk aktivitet. Data kom från en stor RCT, Regassa studien, som bland
annat hade tre träningsgrupper med olika intensitet samt en sedvanlig
behandlingsgrupp.
