Mobile Health Intervention to Promote Positive Infant Health Outcomes in Guatemala

Promoting optimal development for children at risk in low- and middle-income countries (LMICs) is an important global health priority. Supporting caregivers to provide nurturing care is an evidence-based strategy, however feasibility of scaling-up this supporting is limited by competing demands on health workers' time. For infant development, mHealth technologies have the potential to solve this problem by providing tailored content directly to caregivers, involving and empowering them to promote infant development, promoting and facilitating interactions with health workers when areas of concern are identified and, therefore, expanding the reach of healthcare systems. This overall study is designed to explore this idea, by designing a caregiver-directed smartphone application to directly engage first-time caregivers in rural Guatemala in providing nurturing care and, after design, to conduct a prospective implementation trial of its use followed by an adequately-powered efficacy study.
