Mother Screening for Relapse Using Mid-upper Arm Circumference Among Children Recovered From Severe Acute Malnutrition (Full Scale Trial)

A pilot randomized controlled trial for MAMAN was conducted to find if training caregivers to perform mid-upper arm circumference measurements to screen for malnutrition is feasible. This research will be expanded by assessing caregiver screening for detection of moderate acute malnutrition or severe acute malnutrition relapse with a 1:1:1 randomized controlled trial enrolling caregiver-child dyads of an increased sample size of 1200 dyads, totaling 2400 individuals. This study will address the need for evidence of the effectiveness of caregiver administered mid-upper arm circumference screening in the improvement of outcomes for children who have recovered from severe acute malnutrition. The effectiveness of training caregivers to screen for child malnutrition relapse using mid-upper arm circumference tapes, risk of relapse, speed of relapse detection, and anthropometric outcomes of the children will be analyzed. This will assist in providing evidence to incorporate the routine inclusion of mid-upper arm circumference screening training for all caregivers of children who are being discharged from severe acute malnutrition treatment.

SPECIFIC AIM 1: Determine the effectiveness of training caregivers to screen for relapse to moderate acute malnutrition or severe acute malnutrition using mid-upper arm circumference tapes following recovery from severe acute malnutrition for improving anthropometric outcomes and improving time to relapse detection. It is hypothesized that caregiver screening will be effective for reducing time to detection of relapse and that children receiving caregiver screening will have better anthropometric measures at 6 months post recovery and faster time to detection of relapse among those who relapse.

• Specific Aim 1A: Determine if detection of relapse in children who have recently recovered from severe acute malnutrition is more expeditious when caregivers are trained to screen for relapse to moderate acute malnutrition or severe acute malnutrition using mid-upper arm circumference tapes compared to current standard of care. It is hypothesized that a reduction in time to relapse detection will occur when caregivers are trained to screen for relapse to moderate acute malnutrition or severe acute malnutrition using mid-upper arm circumference tapes.
• Specific Aim 1B: Determine the effectiveness of caregivers screening mid-upper arm circumference measurements on improving anthropometric outcomes for children. It is hypothesized that training for caregiver screening of mid-upper arm circumference will lead to earlier intervention and improved anthropometric outcomes for children at 12 months post-admission.

SPECIFIC AIM 2: Determine the acceptability caregiver mid-upper arm circumference training. It is hypothesized that most survey responses at the 3 and 6-month visits will show high levels of acceptance towards caregiver screening of children using mid-upper arm circumference tapes.
