Effectiveness of a Smartphone App (PRIMI) to Promote Healthy Diet and Physical Activity After Pregnancy in Migrant Women

The PRIMI trial (Promoting Reproductive health In MIgrant women) is a randomized controlled trial evaluating the effectiveness of a smartphone app designed to promote a healthy diet, physical activity, and health literacy among first-generation migrant women after pregnancy. The study will recruit 200 women within six months after pregnancy and randomize them into an intervention group, receiving access to the PRIMI app for six months, or a wait-list control group. The primary outcomes are diet quality and moderate-to-vigorous physical activity, while secondary outcomes include health literacy, body mass index, self-efficacy, and self-rated health. The intervention is expected to provide accessible and culturally tailored support to improve postpartum health behaviors.
