- Abstract
<bold>Objective: </bold>To determine the feasibility and effectiveness of an mHealth intervention promoting healthy diet, physical activity and gestational weight gain in pregnant women.<bold>Design: </bold>Randomised controlled trial (RCT).<bold>Setting: </bold>Australian tertiary obstetric hospital.<bold>Population: </bold>One hundred pregnant women who were overweight or obese prior to pregnancy.<bold>Methods: </bold>Women recruited at the first antenatal clinic visit were randomised to either an intervention or a control group. The intervention consisted of a tailored suite of strategies delivered (from first antenatal visit until 36 weeks' gestation) via multiple modalities available on mobile devices.<bold>Main Outcome Measures: </bold>The primary outcome was intervention feasibility and secondary outcomes were objectively measured changes in gestational weight gain (GWG) and self-reported dietary intake and physical activity.<bold>Results: </bold>Ninety-one women completed the study. Delivery to protocol provides evidence of program feasibility. Most women engaged regularly with the program, with the majority (97.6%) reporting that the intervention was helpful. Secondary outcomes demonstrated a significantly lower GWG in the intervention group (7.8 kg ± 4.7 versus 9.7 kg ± 3.9; P =0.041) compared with the control group at intervention completion. Intervention group women reported significantly smaller reductions in total, light- and moderate-intensity physical activity from baseline to completion of the intervention (P = 0.001) compared with the control group, but no differences in consumption frequencies of key food groups.<bold>Conclusion: </bold>An intervention that aimed to deliver healthy diet, physical activity and GWG guidance utilising innovative technology can be feasibly implemented and produce positive physical activity and GWG outcomes. TWEETABLE ABSTRACT: txt4two mHealth study improved gestational weight gain and physical activity in pregnant women with high BMIs.
