Abstract
Mobile health technologies (mHealth) promote the trend towards personal responsibility and self-management. By using the example of type 2 diabetes mellitus (T2DM), the article aims to deepen the discussion on mHealth, personal responsibility and justice-which has so far only been rudimentary-from a public health ethical perspective. It shows that in the field of T2DM, mHealth can on the one hand improve social health justice, but on the other hand can also exacerbate social health injustices. From a justice-focused, public health ethical perspective on T2DM mHealth, it is necessary to better understand whether and how vulnerable population groups are considered in mHealth development and implementation, how these groups experience the use of the technology, what social-epidemiological impacts the increasing use of mHealth can have, which health inequalities in the area of T2DM are unfair, to what extent personal responsibility should be placed in the hands of the users, and where the limits of personal responsibility lie. Considering social diversity and the social determinants of health is an ongoing process and must permeate all phases of mHealth development and implementation.
