The mass growth of protostars is a central element to the determination offundamental stellar population properties such as the initial mass function.Constraining the accretion history of individual protostars is therefore animportant aspect of star formation research. The goal of the study presentedhere is to determine whether high-mass (proto)stars gain their mass from acompact (<0.1pc) fixed-mass reservoir of gas, often referred to as dense cores,in which they are embedded, or whether the mass growth of high-mass stars isgoverned by the dynamical evolution of the parsec-scale clump that typicallysurrounds them. To achieve this goal, we performed a 350micron continuummapping of 11 infrared dark clouds, along side some of their neighbouringclumps, with the ArT\'eMiS camera on APEX. By identifying about 200 compactArT\'eMiS sources, and matching them with Herschel Hi-GAL 70micron sources, wehave been able to produce mass vs. temperature diagrams. We compare the nature(i.e. starless or protostellar) and location of the ArT\'eMiS sources in thesediagrams with modelled evolutionary tracks of both core-fed and clump-fedaccretion scenarios. We argue that the latter provide a better agreement withthe observed distribution of high-mass star-forming cores. However, a robustand definitive conclusion on the question of the accretion history of high-massstars requires larger number statistics.
