This feasibility study has been designed to provide unique data regarding the suitability of an mHealthdelivered intervention to promote healthy diet, activity and weight in pregnant women. Results of comparisons will help assess relevance, applicability and feasibility of
the programme.
A potential limitation of the study is
the reliance on the self-reported pre-pregnancy weight
and nutrition intake and physical activity measures with
the potential for recall bias, and hence, biased analyses.
This is a common concern for GWG, nutrition and
physical activity studies but given the purpose, size and
budget of this study, more detailed assessments were
not considered feasible. Importantly, the study strengths
include the use of multiple technological elements to
appeal to a range of preferences and learning styles and
the potential for sustainable provision within models of
antenatal care
