Following a structured search strategy and a two-phase screening process, 46 studies investigating associations between agriculture and food security or nutrition through the use of simple FGIs were assessed for how the indicators were constructed and interpreted. Most studies based on individual level FGIs were consistent with published guidance, while many of the studies measuring households' dietary diversity were not, particularly in terms of interpretation of the indicators or of food group classification. Efforts are needed to harmonize the way FGIs are used and interpreted in order to enhance comparability across studies and allow meta-analyses of the association between agriculture and food security or nutrition. specialized Dietary diversity Nutrition Food security Agricultural practices Agricultural contexts Critical appraisal 054 076 20 156-169 2019 2211-9124 https://www.documentation.ird.fr/hor/fdi:010075482 10.1016/j.gfs.2019.02.004 2211-9124 [F B010075482] https://www.documentation.ird.fr/hor/fdi:010075482 https://www.documentation.ird.fr/intranet/publi/2019/04/010075482.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-05-13 2025-02-24 fdi:010075482 fre
