Study summary

The goal of this study is to test if a two-way text-message (SMS) maternally administered malnutrition monitoring system (MAMMS) that delivers infant and young child feeding (IYCF) education and supports caregivers in monitoring their child's nutritional status at home can improve nutritional outcomes for HIV-exposed children.

The aims include 1) to determine whether the MAMMS IYCF intervention lowers the incidence of malnutrition, leads to a shorter time to recover for those that become malnourished and results in a lower incidence of hospitalizations, severe malnutrition and death, 2) to determine the cost and cost-effectiveness of the MAMMS IYCF intervention, and 3) to determine the effect of the MAMMS IYCF intervention on the behavior and attitudes of participants through change in age-appropriate feeding, IYCF knowledge, trust in the healthcare system, and intention to seek care if the child becomes wasted.

The study team will enroll 776 caregiver-child pairs aged between 6 and 24 months in Migori and Homa Bay County, Kenya. Each caregiver-child pair will be randomly assigned to either the MAMMS IYCF intervention or standard of care (SOC) and followed for 180 days (about 6 months).

Caregivers assigned to the intervention arm will be asked to respond to weekly messages with the color of the MUAC tape after measuring their child's arm after being trained on how to use the MUAC measuring tape. Weekly messages will include IYCF education and other age-appropriate child health related information. Caregivers in the SOC arm will receive clinic appointment and study visit reminders only. Caregivers in the intervention arm and the SOC arm will be asked to attend the study clinic for follow-up visits at Day 90 and Day 180. At enrollment and follow-up visits, the study team will administer a survey including a child's medical history, a standardized child clinical examination, and anthropometry.

Read the detailed description

The investigators propose an individually randomized trial of MAMMS-IYCF against a standard of care in which nutritional screening and treatment is undertaken in accordance with Kenyan national guidelines by MOH clinicians. This study will not be blinded as the two-way mHealth system requires active patient engagement.

All children attending EID or HIV-care clinics in each health facility will be screened by the study staff for eligibility. Eligible children will be 6 months to 2 years of age (24 months) and exposed to HIV. Children with moderate or severe wasting (MUAC \<12.5cm if older than 6-months, weight-for-height z-score \<-2, or nutritional edema) at the time of screening will be excluded and referred for care. Written informed consent will be obtained in the caregivers chosen language.

After consent is provided, the child and caregiver's full socioeconomic and medical history will be taken including information on uptake of HIV specific managements. All enrolled children will participate in a physical examination performed by a study clinician trained in anthropometry, including dual measurement of length, weight, and MUAC, with a third measurement if there is >10% variability. Anthropometry of enrolled caregivers will also be done at enrollment, which includes height, weight and MUAC measurements. No biological samples will be collected during this study. A caregiver questionnaire will be administered including assessments of caregiver IYCF knowledge, trust in nutritional services, and intention to seek care if they believed their child to be wasted. Finally, all caregivers will be given basic nutrition education prior to randomization and will be trained on the use of MUAC tapes using a swap validation exercise in which caregivers will measure their child's MUAC and a study staff member will measure MUAC and the measurements will be compared for consistency. Training prior to randomization prevents biased exclusion of caregivers unable to pass swap validation.

Block randomization (1:1) with random sized blocks of no more than 12 will be developed by an independent biostatistician. Intervention arm allocation will be concealed in envelopes until the point of randomization. To ensure adequate numbers of HEU or CLWH in both arms, randomization will be stratified by known HIV status at enrollment using separate sets of envelopes for each status.

All caregivers randomized to the MAMMS-IYCF arm will be given two MUAC tapes after being trained by skilled study staff and their contact information will be entered into the online MAMMS-IYCF platform. The frequency of messages will be weekly. This will be a two-way SMS system and the content of each message was determined during the intervention pilot (KEMRI/SERU/CCR/309/4754), including health messages on age appropriate IYCF. These messages will also prompt caregivers to measure their child's MUAC, return the color outcome of the measurement to the clinic via the SMS system, and they will also be able to ask any health questions that they may have through the SMS. Separate automated messages will provide reminders of upcoming clinical or research visits that the caregiver and child require, to ensure good attendance at these visits. The caregivers can choose to receive these SMS in any of the four languages commonly spoken in the region: English, Swahili, and Luo. They can also choose the day and time messages are sent to them. The SMS messaging service will be free of cost to the caregivers as they will not incur any charges to send or receive messages while enrolled in the trial.

During follow-up, any caregiver who returns a MUAC measurement via SMS that suggests their child is wasted (yellow/red on the MUAC tape), will receive an SMS response asking them to come to the clinic with their child as soon as possible and this request will be followed up with a phone call. At this visit, the wasting status of the child will be confirmed by a study staff, and if treatment is indicated they will be enrolled into nutritional care provided by MOH nutritionists. If the caregiver incorrectly measured the MUAC, repeat training will be offered.

To promote high fidelity to current guidelines, all families randomized to the SOC arm will be enrolled into a one-way SMS service that will send them automated reminders before necessary routine EID or HIV care visits and research clinic appointments on day 90 and 180. During these routine clinic visits, study staff will ensure that the MUAC of SOC children are measured, and that treating clinicians (MOH nutritionists) are made aware if wasting is identified. Staff will ensure that SOC children are enrolled into nutritional care if they are wasted. This additional support means it is likely that SOC children in this study will receive care that is more adherent to current recommendations than is typical for many children. This enhanced SOC is necessary to ensure the investigators are comparing the MAMMS-IYCF to current guidelines. The SMS messaging service will be free of cost to the caregivers as they will not incur any charges to send or receive messages while enrolled in the trial.

Caregiver-child pairs will be asked to attend the research clinic at 90 and 180 days after enrollment to administer a follow-up CRF, take anthropometry measurements (height, weight and MUAC measurements) and collect recalled morbidity events. Where possible these visits will immediately follow routine clinical appointments, minimizing the travel burden on families. The investigators will also take anthropometry measurements of caregivers (weight, height and MUAC measurements) at 90 and 180 days after enrollment. At the final study visit, an SMS acceptability questionnaire will be administered to caregivers in the intervention arm to record any challenges or discomfort they felt using the system along with the pre/post-intervention secondary outcome survey questions. Any child noted to have malnutrition at the final study visit will be referred for treatment (a MUAC less than 12.5cm or any other common symptoms of malnutrition) and be administered with the acceptability questionnaire. During the study, caregivers will also be encouraged to come to the health facility for any medical concerns arising outside of the standard visit schedule.

The acceptability and feasibility of the MAMMS-IYCF intervention will be evaluated using a mixed-methods assessment of caregiver and nutritional program worker experiences and insights. In the RCT, all caregivers in the MAMMS IYCF arm will be administered an SMS acceptability questionnaire at study completion (180 days or the time at which a child is identified as malnourished), that will use Likert scores to quantify key indicators of participant satisfaction, tool acceptability, appropriateness, and feasibility. At completion of study, a subset of caregivers from the intervention arm across both study sites will be selected for focus groups discussions (FGD) or in-depth interviews if less than 15 participants are available to participant in each sampling group e.g. mothers of children with malnutrition and mothers of children who did not develop malnutrition. Focus group or in-depth interview participants will be randomly sampled from the pool of mothers, with 5-8 mothers sampled to participate in each FGD. If we do not have enough participants for the focus groups, we will conduct in-depth interviews with a subset of 5 participants in each of the following groups.

Two focus groups for each of the following sets of mothers will be conducted (possible range of 2-5, based on data saturation), with a minimum of eight focus groups in total. If less than 15 participants across both sites are available to participate from each sampling group, we will conduct in-depth interviews instead with 5 participants in each of the following groups (1) intervention arm participants whose child did not develop acute malnutrition, (2) intervention arm participants whose child developed acute malnutrition malnourished.

To complement, the investigators will conduct in depth interviews with mothers in the intervention arm to assess drivers of engagement with the platform. This includes about 10-16 caregivers who participated in the MAMMS intervention at varying levels of engagement.

The investigators will also conduct in-depth interviews with nutritional staff currently active in Migori and Homa Bay Counties and MAMMS-IYCF staff. Individual interviews will be conducted with purposively sampled health volunteers, including up to ten community health volunteers, three nurses, three nutritionists and three nutrition program managers (N=19 interviews with project implementers). The individual interviews will be used to understand health worker perceptions of the MAMMS-IYCF model, potential barriers to sustaining or scaling the program, and opportunities to improve the program moving forward. All FGDs and interviews will be conducted in the participant's preferred language (Kiswahili, Luo, or English) by a trained qualitative researcher and audio recorded for subsequent analysis. Interviews may be conducted in lieu of FGDs depending on the COVID-19 situation to respect social distancing recommendations.

What researchers measure

Primary outcomes

  1. Children randomized to MAMMS-IYCF will have a lower incidence of wasting, and shorter duration of wasting treatment due to early initiation of treatment.

    Assessed by measuring the incidence of healthcare worker confirmed wasting (weight-for-height z-score \<-2, nutritional edema, or MUAC \<12.5 cm for children ≥6-months of age) and the mean duration of treatment defined as the number of days between enrollment in malnutrition treatment to the last treatment visit

    Time frame: From enrollment to the end of follow-up at 180 days

Secondary outcomes

  1. The MAMMS-IYCF arm will have fewer hospitalizations compared to the SOC arm

    Assessed by calculating the number of hospitalizations reported in both arms throughout the data collection period and compared

    Time frame: From enrollment to the end of follow up at 180 days

  2. The MAMMS-IYCF arm will have fewer deaths compared to the SOC arm

    Assessed by recording and comparing the number of deaths reported in each arm throughout the duration of data collection

    Time frame: From enrollment to the end of follow up at 180 days

  3. The MAMMS-IYCF arm will have fewer cases of severe wasting compared to the SOC arm

    Assessed by comparing the number of cases of wasting (calculated by a MUAC measurement less than or equal to 12.5cm or weight-for-length Z-score less than or equal to 2) reported in both arms.

    Time frame: From enrollment to the end of follow up at 180 days

  4. MAMMS-IYCF will be lower cost and more cost-effective from both provider and societal perspectives

    The incremental costs of implementing MAMMS-IYCF above the SOC will be calculated using activity-based micro- costing to assess both economic and financial costs from the payer (health system) perspective.

    Time frame: From enrollment to the end of follow up at 180 days

  5. Number of caregivers reporting their child received age appropriate feeding as defined by WHO at each study visit will be higher in the MAMMS IYCF arm compared to the SOC arm

    Age-appropriate feeding will be defined by meeting all relevant criteria in the WHO definition of age-appropriate IYCF: 1) exclusive breast feeding until six months of age, 2) continued breastfeeding to at least two-years of age, 3) a diverse diet including 5 of 8 food groups from the WHO minimum dietary diversity tool, 4) 2-4 meals per day dependent on age, and 5) consumption of iron rich foods. This will be quantified as the number of visits at which caregivers report their child to have met age-appropriate feeding criteria on the day before the clinic visit as reported using questionnaires adapted from WHO on dietary diversity and iron rich foods. The total number of children that received age-appropriate feeding at study visits will be compared between arms.

    Time frame: From enrollment to the end of follow up at 180 days

  6. Caregivers of children randomized to MAMMS-IYCF will report higher trust in healthcare services and would be more likely to seek medical or clinical care if they believed their child was wasted, compared to caregivers in the SOC arm

    Assessed using baseline and endline questionnaires adapted from the Trust in Physician scale (1=Strongly Disagree to 5= Strongly Agree), General Help Seeking Questionnaire (1 = Extremely Unlikely 3 = Unlikely 5 = Likely 7 = Extremely Likely) and an IYCF knowledge questionnaire developed by the study team (incorrect responses = 0, correct responses 1)

    Time frame: From enrollment to the end of follow-up at 180 days

  7. Coverage (90 days)

    The proportion of children with acute malnutrition at 90 days who are receiving treatment, measured as the number on treatment at 90 days divided by the number who are acutely malnourished at 90 days

    Time frame: From enrollment to the day 90 study visit

  8. Coverage (180 days)

    The proportion of children with acute malnutrition at 180 days who are receiving treatment, measured as the number on treatment at 180 days divided by the number who are acutely malnourished at 180 days

    Time frame: From enrollment to the 180 day study visit

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 19, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
