(P14-002-20) Developing Caregiver Led mHealth Solutions for Screening and Managing Childhood Wasting in the Mama Aweza Trial in Kenya

Objectives: Globally, only 17% of children with wasting receive treatment. In Kenya, 4% of the 7 million children under-5 years of age are wasted and 26% are stunted. The Mama Aweza trial will test whether a two-way short message service (SMS) mobile health system, the Maternal Administered Malnutrition Monitoring System (MAMMS), can increase the coverage of malnutrition management programs in low-and-middle income countries.

Methods: Five formative focus group discussions (FGDs) were conducted with caregivers at an immunization clinic in Migori County, Kenya to inform feasibility and content of SMS messages in the MAMMS system. Caregivers were asked to explain anticipated facilitators and barriers to participation in a SMS program to facilitate home-based mid upper-arm circumference (MUAC) monitoring. FGDs also reviewed educational messages that accompany weekly SMS reminders to measure and report their child’s MUAC. The feedback from these FGDs was included in the clinical trial, which begun in August 2019.

Results: The most anticipated challenge to responding to weekly messages was the use of a shared phone particularly that the SMS would be deleted or the caregiver would not be informed of the message. The greatest anticipated challenge for sending messages was and not knowing how to send a SMS. Overall, 52 messages were written on the following topics: developmental milestones, encouragement, fever, diarrhea, malaria, ear infections, sanitation and hygiene, vaccinations, respiratory illness, and kitchen gardening. To date, 144 mother-infant dyads have been enrolled and 77 randomly assigned to the MAMMS arm. Sixty-nine (90%) caregivers have responded to ≥1 message and 503 (68%) of 742 automated messages have received a response. At enrollment, 21 (27%) of caregivers in the MAMMS arm reported a shared phone, with no current evidence that caregivers sharing a phone respond less than those with their own phone.

Conclusions: Caregivers found SMS-based malnutrition screening to be acceptable and engaging. In regions with high literacy and high mobile phone ownership, such as Kenya, SMS supported home MUAC monitoring may improve malnutrition screening coverage and lead to earlier identification and treatment.
