We calculate the finite-temperature thermal effective mass for one-dimensional systems within the plasmon-pole approximation. We find that the calculated temperature denpendent effective mass including exchange and correlation is non-monotonic. In quantum wire systems at low-density the mass effective decreases as first with increasing the density, but after reaching a minimum it increases as the density is raised further. We find the leading order temperature correction to the mass effective within the plasmon-pole approximation to be increase at low temperature for all the densisty.
