Organization of presentation
• Key ideas associated with PM2A– The window of opportunity (“1000 days”)– Prevention – The UNICEF model
• What started it all: the Haiti study (2002-2006) • What next? The rationale behind the
Guatemala and Burundi studies
Key idea #1 of PM2A: Why up to 24 months?
Period of greatest vulnerability and of greatest opportunity.
The quality of nutrition in the first two years affects a person for a lifetime
1. Chronic malnutrition begins early*

Key idea #3: the UNICEF Model
Core package of PM2A• Food. Usually includes
– Family ration to improve HH FS and access to foods of higher quality (FBF). – Individual ration for direct beneficiaries to increase nutrient intake.
• Health: Includes: – regular visits to health centers to seek preventive/curative H/N services for:
• PLW (pre- and postnatal care, assisted delivery & postnatal controls)• Children under 2 (immunization, Vit A, deworming, DD prevention/management, malaria
prevention strategies, prevent/treat iron deficiency, GMP
– Active case finding and referral of children with SAM
• Care practices. BCC strategy to: – improve IYCF, hygiene, health seeking behaviors– stimulate adoption of recommended practices/use of available services, – teach how to use donated/local foods – ensure targeted beneficiaries access the services and donated food.
• As any preventive intervention, PM2A targets ALL children -9/+24)
In sum: PM2A Key Elements
• Focus on the 1000 days• Follows public health notion of prevention
(all children are covered)• Interventions are based on the UNICEF
conceptual model
• Those three elements are key. • The “How” can change, not the “what”
Based on a MYAP implemented by World Vision in Haiti’s Central Plateau between 2002 and 2005
Cluster randomized trial (no controls)Study carried out by IFPRI
Goal: compare the relative merit of preventive vs recuperative programming to reduce population
level of child malnutrition Refs: Lancet paper, Propensity Score Matching
paper, various documents on FANTA-2’s website
The FANTA/IFPRI/World Vision study
At final survey preventive communities had better anthropometry than recuperative ones

Comparing with DHS surveys 2000 and 2005 (NCHS standards)
Stunting increased by 10ppt in the region
Stunting stayed same in Recup. arm
Stunting reduced by 7ppt in Prev. arm
Costs
• Both models have same direct program costs (in spite of the larger number of beneficiaries in preventive)
• Food costs are higher in the preventive approach due to the larger number of beneficiary-months
• Costs per beneficiary/month are lower in preventive:– direct program costs/beneficiary-mo are lower and – food costs/beneficiary are the same
Summary of findings from Haiti study
• Preventive model generated: – Lower prevalence of stunting, underweight,
wasting– Higher mean HAZ, WAZ, WHZ– Results were consistent across age groups
• Preventive model also improved HH food security
• Cost per unit of improvement were lower in the preventive model
FFP’s PM2A initiative
• Based on Haiti findings: – FFP modified its guidance, specifying PM2A as the
preferred MCHN approach for its Development Programs– FFP funded additional study of PM2A in 2 countries
(Burundi, Guatemala) to improve efficiency of PM2A• What makes the preventive model works?• Can the cost of PM2A be reduced?
• MYAPs will receive $10M/yr for 5 years in each ($100M total); study will cost $8M total for 5 years in 2 countries
• MYAPs started 2010; study enrollment started 2011
Specific Objectives of the PM2A study• Assess the impact and cost-effectiveness of PM2A on child
nutrition • Assess the importance of food ration (size/type)
– Large, Reduced, or No Family Rations? – Individual Rations, Lipid-based Nutrient Supplements, or
Micronutrient Sprinkles?• Assess the impact of the duration of exposure on child
nutrition • Not an objective:
– Assess the impact of BCC only– Assess the impact of no food at all (no individual nor FR)
Key outcomes examined
• Child nutritional status– Linear growth– Micronutrient status
• Other child outcomes– Motor development– Cognition– Morbidity
• Secondary outcomes– HH FS– Maternal nutrition (Hb)
Burundi
• MYAP implemented by CRS-led consortium (with participation of IMC, FH, CARITAS/Bur)
• Study carried out by IFPRI • Cluster randomized controlled trial• 2 cross sectional surveys (Baseline/Endline)• 3 study arms
– PM2A (-9 to 24mo, full FR, BCC, HS)– PM2A until child is 18 mo (instead of 24)– Control” No services from MYAP (only regular Gov’t
ones)
Guatemala• MYAP Implemented by Mercy Corps in Alta Verapaz• Study carried out by IFPRI • Cluster randomized controlled trial• 2 cross sectional surveys (Baseline/Endline)• Longitudinal study repeated at 1, 4, 6, 9, 12, 18, 24 mo• Six “study arms”
i. PM2A: “Full” PM2A (-9 to 24mo, full FR, BCC, HS)ii. PM2A/.5FR: PM2A with smaller (1/2) family ration iii. PM2A/0FR: with no family rationiv. PM2A/LNS: PM2A w/LNS (no food) as individual child rationv. PM2A/MNP: PM2A w/MNP (no food) as individual child ration vi. Control: No services from MYAP (only regular Gov’t ones)
Questions to study size of family rations and comparisons used
Does PM2A with a reduced FR improve child NS?
PM2A/.5FR vs CTRL
Do large FR have a larger impact on child NS than reduced FR?
PM2A/.5FR vs PM2A
Does PM2A without a FR improve child NS?
PM2A/0FR vs CTRL
Are FR necessary for PM2A to impact child NS?
PM2A/0FR vs PM2A

Does PM2A w/LNS have the same or more impact than PM2A w/MNP on child NS?
PM2A/MNP vs PM2A/LNS
Questions to assess the impact of different duration of PM2A and comparisons used
Does a PM2A program that provides benefits to children up to 18mo have an impact on NS?
PM2A/18 vs CTRL
Is it necessary to provide benefits up to 24mo for impact on child NS, or is 18 months sufficient?
PM2A/18 vs PM2A
Questions to assess the impact & cost-effectiveness of PM2A on child nutrition
Does PM2A improve child NS compared to Ctrl?
PM2A vs Control
What is the cost & cost-effectiveness of PM2A?
PM2A vs Control
Additional studies
• Formative research (to develop the BCC strategy) • Operations research (throughout implementation)• Cost study to assess cost effectiveness and cost
benefit of the different study arms• Special studies: tbd
– Intra-HH utilization of food commodities– Side effects of food aid on production, fertility decisions
Next steps
• Studies to be finalized in 2015… • Publications in peer-reviewed journals• Revision of the FANTA-2 TRM• Development of additional tools to help
programming, e.g.: – Costing tool– Ration size calculator
• Meanwhile, FANTA-2 will continue to provide technical support to PVOs in PM2A implementation
