Maternal Obesity Management using Mobile Technology (MOMTech): the results from a feasibility study

Background: Maternal obesity and excessive gestational weight gain (GWG) are increasing in prevalence with a negative impact on pregnancy and birth outcomes. This study aimed to evaluate the feasibility and acceptability of a text messaging based complex intervention designed to support obese women to avoid excessive GWG through healthy eating and physical activity. Methods: The complex intervention consisted of diet and activity goal setting and review (in four appointments with a midwife), weekly self-monitoring of diet and physical activity, and the receipt of daily preselected text messages. Interviews and focus groups were conducted postnatally. Findings: Fourteen women completed the study. Participants had a lower mean GWG (6.65kg compared to a comparison group 9.74kg). Interviews/focus groups revealed that participants were positive about the intervention, and reported that the text messages served as good reminders of their goals. Suggested improvements included more variety in the text messages. Discussion: MOMTech appears to be feasible within a clinical setting and an acceptable intervention to support women to limit GWG. The findings will be used to refine and simplify the intervention prior to trial.
