Maternal health outcomes is a global midwifery concern. This systematic review and meta-analysis evaluated the effectiveness of mobile health (mHealth) interventions on four key maternal and child health outcomes: antenatal care (ANC) attendance, facility delivery, exclusive breastfeeding at 5–6 months, and completion of childhood immunisation at 9 months. A literature search of electronic databases identified eligible randomised controlled trials published between 2020 and 2025. Data were synthesised using a random-effects model, with effect sizes reported as pooled relative risks and statistical significance assessed at p < 0.05. The review found that mHealth interventions significantly improved ANC attendance 50% (RR: 1.5 (95%CI: 1.02-2.18)). In contrast, mHealth did not significantly influence facility delivery, exclusive breastfeeding practices, or childhood vaccination completion at 9 months. The results underscore the differential impact of mHealth across the maternal care continuum. This review provides evidence that mHealth has substantial potential to improve ANC uptake but requires strategic adaptation to meaningfully influence other maternal and child health outcomes.
