[Determinants of linear growth retardation in Brazilian preschool children: a multilevel approach].

This study focuses on the determinants of linear growth deficit in under-five children using multilevel modeling. The sample included 3,746 preschoolers from 15 Brazilian municipalities (ten from the State of Bahia and five from São Paulo), with a three-tier analysis (municipalities, households, and children). Municipal data were obtained from the 1991 National Census.
