Predictors of Stunting and Pathway Analysis for Linear Growth among Children Aged Two to Three Years after a Trial of Small-Quantity Lipid-Based Nutrient Supplements and Home-Installed Growth Charts in Three Districts in Zambia.

Background: Globally, 148 million children aged <5 y are stunted, with risk factors varying by context. Our "Impact of Growth Charts and Nutritional Supplements on Child Growth in Zambia" (ZamCharts) trial observed persistently high rates of stunting in all treatment groups after 18-mo of intervention with monthly distributions of small-quantity lipid-based nutrient supplements (SQ-LNS) and/or installation of a wall-mounted growth chart in children's homes.

Objectives: We sought to identify determinants of stunting and height-for-age z-score in children aged 27-36 mo who participated in the ZamCharts endline survey (n = 1911).
