Using mHealth to Deliver Behavior Change Interventions Within Prenatal Care at Community Health Centers.

<bold>Purpose: </bold>To test an iPad-delivered multiple behavior tailored intervention (Healthy Pregnancy: Step by Step) for pregnant women that addresses smoking cessation, stress management, and fruit and vegetable consumption.<bold>Design: </bold>A randomized 2 × 5 factorial repeated measures design was employed with randomization on the individual level stratified on behavior risk. Women completed three sessions during pregnancy and two postpartum at postdelivery months 1 and 4.<bold>Setting: </bold>Women were recruited from six locations of federally funded health centers across three states.<bold>Subjects: </bold>Participants (N = 335) were English- and Spanish-speaking women at up to 18 weeks gestation.<bold>Intervention: </bold>The treatment group received three interactive sessions focused on two priority health behavior risks. The sessions offered individually tailored and stage-matched change strategies based on the transtheoretical model of behavior change. The usual care group received March of Dimes brochures.<bold>Measures: </bold>The primary outcome was the number of behavior risks. Stage of change and continuous measures for all behaviors also were assessed.<bold>Analysis: </bold>Data were analyzed across all time points using generalized estimating equations examining repeated measures effects.<bold>Results: </bold>Women in the treatment group reported significantly fewer risks than those in usual care at 1 month (.85 vs. 1.20, odds ratio [OR] = .70) and 4 months postpartum (.72 vs. .91, OR = .81).<bold>Conclusion: </bold>Healthy Pregnancy is an evidence-based and personalized program that assists pregnant women with reducing behavior risks and sustaining healthy lifestyle behaviors.
