"Every pregnancy is different"

This is the authors' abstract. We don't add key points for this paper.

This paper presents the results of an ongoing study into the potential role of mobile or wireless health applications for targeting the prevention of excessive gestational weight gain in pregnant lower-income American women. Informed by a qualitative study of pregnant women's experiences, we develop a set of design requirements for designing mobile health (mHealth) interventions related to healthy pregnancies. We identify a disconnection between physical activity and food tracking application design paradigms, and the reality of pregnant women's lives and capacities. We introduce the concept of an individualized pregnancy ecology, which provides an alternative paradigm for design of health and wellness management tools for lower-income pregnant women.
