  abstract = {{Q}uantitative assessment of foods consumed when using 24-hour dietary recall requires accurate tools to estimate portion sizes. {T}herefore, we developed a food portion photography atlas with age-appropriate portion sizes for 11 foods frequently consumed by young children (sizes for 6-11-month- and for 12-23-month-old children) and women of childbearing age in {O}uagadougou, {B}urkina {F}aso capital. {W}e then compared the accuracy and precision of portion estimation with this atlas and with salted replicas relative to weighed records (the reference). {A}fter weighing, we randomly assigned food portions to 67 women and their children. {T}he next day, women estimated the served portions and leftovers by recall using the atlas and then salted replicas (n = 1156 measurements, ranging from 19 to 113 for each food). {F}or most food types, the portions estimated with the atlas and salted replicas were positively correlated and showed good concordance with the weighed records. {H}owever, accuracy and precision varied in function of the estimation method, food type, and age group. {T}he mean crude differences ranged from -28 to +12g (with errors in absolute values from 24 to 69%) for children, and from -32 to +44g (errors from 17 to 56%) for women. {T}he atlas-based method showed the lowest {L}in's concordances (coefficients of 0.1 to 0.2) for the leafy vegetable dish, meat, and fish in 12-23-month-old children. {B}land-{A}ltman plots indicated that the salted replicas allowed estimating the consumed portions with fewer errors than the photographic atlas (56 to 91% vs 46 to 79% between the limits of & {PLUSMN};50%). {O}ur study highlights that mothers have difficulties in perceiving the quantities of food consumed by their children. {O}ur findings also indicate that the food atlas could be used in food consumption surveys when salted replicas are not available for all food types.},
