21 views

Published on

A new study by Transform Nutrition West Africa identifies the trends and gaps in research that cover the World Health Assembly indicators across West Africa. These are potentially valuable insights for nutrition decision makers in the region. This presentation is to be used as a freely accessible resource for decision-makers at all levels.

Senegal Systematic Map to Guide decision-making on the current landscape of research on World Health Assembly indicators in West Africa

  1. 1. Senegal International Food Policy Research Institute The Current Landscape of Research on World Health Assembly Indicators in West Africa: A Systematic Map to Guide Decision-Making
  2. 2. 2 The West Africa (WA) Region has been one of the slowest in reducing its many burdens of malnutrition. The World Health Assembly’s (WHA) 2025 nutrition targets were developed to track countries’ nutritional situations, and measure progress in reducing malnutrition. These indicators are therefore essential to guide decision making. Understanding the regional and in-country dynamics are an essential first step to highlight gaps and trends in evidence in the region. Introduction This study aimed to identify and catalogue peer-reviewed research on the WHA indicators in West Africa, and create a map of recent research evidence to inform decision-making for nutrition policies and programs in the region. Objective
  3. 3. Data were extracted at abstract level. No quality appraisal of publications was undertaken A systematic approach was applied to literature searches, developing inclusion criteria, screening, coding, taxonomy, data extraction, and study synthesis The MEDLINE database was searched for research published on World Health Assembly (WHA) indicators from 2010 to April 2018 Search terms were developed to capture evidence on the prevalence, drivers, programs (Randomized Controlled Trials), and policies relating to the WHA indicators. These include stunting, wasting and overweight in children under 5, low birth weight (LBW), exclusive breastfeeding (EBF) up to 6 months, and anemia in women of reproductive age (WRA) Methods
  4. 4. References identified through systematic search (n=6,630) References excluded (n=2,581) - Not WA region (n=130) - Not target population (n=172) - Disease specific/not nutrition related (n=1729) - Nutrition related but not WHA specific (n=337) - Additional program studies (n=75) - RCT Protocol (n=9) - Other (n=129) Duplicates removed (n=3,669) References retrieved after title and abstract screening (n=380) - Primary studies (n=359) - Reviews (n=21) References retrieved for title and abstract screening (n=2,961) References included in mapping (n=363) Primary Studies (n=340) Reviews (n=23) Excluded at extraction level (n=17) Flow chart of search approach
