Demographics and prevalence of infant stunting by study site (n 306). Data were obtained from newborns with a median age of 19 d from eight rural villages (n 200) and an urban clinic (n 106) in Quetzaltenango, western highlands of Guatemala

HAZ, length-for-age Z-score.

^*Based on 2006 WHO growth standards^{( 4 )}.

^†Stunting was defined as HAZ <−2·0 in relation to the WHO reference median^{( 4 )}.

^‡Severe stunting was defined as HAZ <−3·0 in relation to the WHO reference median^{( 4 )}.
