About

eCHANGE Research

Read full description

eCHANGE er utviklet for å støtte vektstabilisering etter vekttap. Etter å ha gått ned i vekt, er det mange som opplever det utfordrende å holde vekten nede over tid. Avdeling for Digital Helseforskning (DIG) ved Oslo universitetssykehus har, sammen med Sykehuset i Vestfold og Sørlandet Sykehuset, utviklet eCHANGE et digitalt program for vektstabilisering. Verktøyet er basert på forskning, evidensbaserte metoder, og brukererfaringer.    Ved å bruke eCHANGE til å regulere daglige rutiner og adferd kan nye levevaner tilegnes og opprettholdes over tid, med stabilisering av vekt som et langvarig resultat. eCHANGE benytter seg av HealthKit-integrasjon på din enhet slik at du om ønskelig kan hente enkelte data fra andre helseapper og bruke disse i eCHANGE.   Her finner du mer informasjon om forskningsprosjektet eCHANGE: https://www.digitalhealth.no/prosjekter/echange/index.html
