  abstract = {{T}he number of urban poor is increasing quickly in {W}est {A}frica, yet food security early warning systems still do not include urban areas. {O}ne reason is the lack of appropriate and internationally agreed-upon indicators to measure urban household food insecurity. {O}ur objective was to assess the performance of the household food insecurity access scale ({HFIAS}) and an index-member's dietary diversity score ({IDDS}) to approximate the adequacy of urban households' diets. {A} survey was performed on a random cluster sample of 1056 households in {O}uagadougou, {B}urkina {F}aso. {D}ata on {HFIAS} and {IDDS} and 2 nonconsecutive household quantitative 24-h recalls were collected twice, in {J}une-{J}uly and in {N}ovember-{D}ecember 2007. {D}iet adequacy was assessed through the household's mean adequacy ratio ({MAR}) using energy and 11 micronutrients. {S}tructural equation modeling was used to quantify the association of each candidate indicator with the {MAR} and receiver-operating characteristic ({ROC}) analyses were performed to assess their targeting performance in predicting low or high {MAR}. {HFIAS} was negatively associated with the {MAR} [path coefficient ({P}) = -7.95 × 10-3 ± 1.45 × 10-3; {P} < 0.001], whereas {IDDS} was positively associated with it ({P} = 5.19 × 10?2 ± 1.27 × 10-2; {P} < 0.001). {A}reas under the {ROC} curves ranged from 0.585 to 0.661 for {HFIAS} and from 0.536 to 0.629 for {IDDS}. {I}n conclusion, {HFIAS} and {IDDS} performed well in approximating adequacy of urban households' diets. {T}hey are informative indicators about urban food insecurity, promising for evaluation and monitoring but not for household targeting given their insufficient predictive power.},
