Table 2. Top ten research questions according to the overall research priority score (RPS).

Rank	Research question	Group	A	E	D	F	RPS	AEA	N
1	What is the impact of interventions for managing at-risk mothers and infants less than 6 months of age in preventing wasting/acute malnutrition in the >6months old?	Description	97.5	96.7	93.9	95.9	96.0	93.1	122
2	What is the impact of growth failure during the first 6 months of life on experience of wasting/acute malnutrition after 6 months of age?	Description	96.3	88.0	88.9	89.3	90.6	86.4	117
3	How can existing interventions (e.g. growth monitoring, integrated management of childhood illness (IMCI)) better detect and support children (0–59 months) who are failing to thrive/faltering (i.e. those at-risk, not just those already below a z-score threshold)?	Development	91.4	90.1	89.8	87.8	89.7	85.6	131
4	What are effective and cost-effective approaches to target the highest risk infants and children 0–59 months (e.g. children with concurrent wasting/acute malnutrition and stunting, children <24 months, etc.) for interventions (food or non-food) to prevent wasting/acute malnutrition?	Delivery	93.3	89.4	85.4	88.4	89.1	84.7	129
5	What measures (anthropometric or non-anthropometric) or combinations of measures best identify individual infants and children (0–59 months) by age/sex at most risk of death/other adverse outcomes associated with wasting/acute malnutrition?	Description	91.9	89.2	87.4	85.5	88.5	82.8	128
6	What is the role of pre-pregnancy maternal factors (age, health status, nutritional deficits, psychological factors etc.) in determining risk of being born with a low birth weight, low weight-for-length, low mid-upper-arm circumference, premature or small for gestational age?	Description	96.7	87.6	86.4	83.2	88.5	83.2	122
7	What measures (anthropometric or non-anthropometric), or combinations of measures, best identify individual infants and children (6–59 months) by age/sex at most risk of wasting/acute malnutrition?	Description	92.3	88.2	89.0	81.3	87.7	82.0	128
8	What are effective and cost-effective approaches to integrating wasting/acute malnutrition prevention efforts into health systems (i.e. human resource capacity, financing, supplies and supply chain, etc)?	Delivery	86.0	89.9	84.3	89.5	87.4	81.0	128
9	What impact can effective wasting/acute malnutrition prevention interventions/approaches have on levels of stunting (and concurrent wasting and stunting) and vice versa?	Description	89.5	85.5	85.0	87.2	86.8	79.5	125
10	How does being born prematurely and/or with foetal growth restriction impact on wasting/acute malnutrition at birth and throughout the first 5 years of life, by sex?	Description	93.0	81.6	83.8	86.5	86.2	80.2	122
