1 MANAGING ACUTE MALNUTRITION IN INFANTS (MAMI): WHERE ARE WE NOW? Nicki Connell, Emergency Nutrition Advisor, SCUS Date: 19 th October 2016

2 Managing Acute Malnutrition in Infants (MAMI) Presentation Flow Background on the problem Updates: Research in Bangladesh on obtaining evidence on risk factors for infant malnutrition Prevalence survey data Prospective follow-up study Development of Community-MAMI (C-MAMI) guidance note 2

5 Background Acute malnutrition is a major global public health problem causing ~45% of all child deaths each year =6.3 mil in 2013 (WHO, Sept 2014) Over the last decade, management of Severe Acute Malnutrition (SAM) and Moderate Acute Malnutrition (MAM) in children aged 6 59 months has been revolutionized by a public health orientated model of care, "Community based Management of Acute Malnutrition" (CMAM) not the case for infants under 6 months 5

6 Background Typically the current national SAM guidelines only recommend inpatient/clinical care for infants <6m with SAM This is problematic: Cost to health system Cost to family Adherence to protocols High number of defaulters Risk of infection 6

7 Recent Updates by WHO in late 2013! Recommend outpatient management of malnutrition in infants BUT Lack of practical guidance on how to identify those at risk and how to manage those identified 7

8 Current definition of severe acute malnutrition (SAM) in infants <6m old Weight for length of less than 3 Z score Visible severe wasting Edema (bilateral pitting edema) 8

10 MAMI Research in Bangladesh Objectives To estimate the prevalence of infants<6m with acute malnutrition in the community av To develop an assessment tool/case definition checklist for infants<6m with acute malnutrition Anthropometric criteria/breastfeeding assessment/clinical criteria/ Other criteria e.g. lack of social support; disability; maternal education; source of water, sanitation, housing, maternal anthropometry To describe current outcomes following infant <6m with acute malnutrition 10

11 MAMI Research in Bangladesh Study components Prevalence survey: A group of infants have been identified from house to house searching for anthropometric measurements; in two distinct seasons av Prospective follow-up study: 3 groups of infants who are SAM (WFH <-3 and/oedema), Not SAM (WFH >-2, no oedema, MUAC >115) and with Low MUAC (MUAC <115); will be followed up until they are 180 days old 11

13 MAMI Research in Bangladesh Methodology Prevalence Survey x2 (pre and post harvest) Study participants: infants aged <6months of either sex Targeted sample size: 742, Identified randomly among 106 villages av Check for age using appropriate documents Anthropometric measurements (Weight, Length, MUAC etc.) Check for edema Calculate the weight-for-length and Length-for-Age Z-score and Weightfor-Age Z-score using WHO Growth Standards 2006 Data entry electronically at field, transferred to central server in real time 13

23 Prospective Follow-up Study Objective To take infants with acute malnutrition and compare them with infants without acute malnutrition, to identify what the risk factors for malnutrition are av Looked at a large number of variables in order to identify which are the critical risk factors Once we know the risk factors, we will know what to look for to identify nutritionally vulnerable infants and also ensure these are addressed when managing nutritionally vulnerable infants 23

28 Socio economic Variables Infants were older in Group B compared to Groups A and C (will adjust for age) Household income per month was significantly lower in Group A compared to Groups B&C ($89 vs. $114) Lower number of households had electricity in Group A compared to groups B&C (61% vs %) 28

29 WASH Variables/ Mothers Anthropometry Type of toilet was significantly different between the groups Group A had more people with a pit latrine vs. a flushing toilet compared to groups B&C NB: Hand washing and source of water were not significantly different between the groups Both mother s BMI and MUAC were less in Group A compared to groups B&C 29

30 Infant Feeding Variables Duration of exclusive breastfeeding was shorter in Groups A&C at enrolment and end line (at end line Group B had an average of 20 weeks, vs Group A with 13 weeks and Group C with 16 weeks) At end line, significantly less infants were still being breastfed in Groups A&C than in Group B More infants in Group A and C were fed anything other than breastmilk at enrolment and end line 30

34 Infant Feeding Variables Infants in Groups A&C were given animal milk at an earlier age compared to infants in Group B NB: Duration of breastfeeding was not significantly different between the groups 34

35 Clinical Illness and Maternal Mental Health More infants in Group A had at least 1 episode of illness that required hospitalization at enrolment and it further raised up to 40% at the end line Proportionately more mothers were depressed in Group A than in Groups B&C 35

36 Outcomes of all Groups at 6 months? Around a quarter of the infants remained suffering from SAM in Group A Infant deaths were more in Group A and the cause of death found to be SAM Five percent of the infants in Group C became SAM at the end of the follow up period who were not diagnosed as SAM with the current existing criteria 36

37 Key Next Steps With prevalence survey data, will adjust for all variables to determine if seasonality is a key driver For cohort data, will combine use of infant formula with use of animal milks, as this will be good for policy work For cohort outcomes, critical to note that at 6 months 1/3 had negative outcomes (death, SAM, loss to follow up) so current treatment protocols are not working 37
