Maternal height is associated with mortality and anthropometry in low-and-middle-income countries. This paper explored residual associations and potential underlying mechanisms linking maternal height to several child outcomes using regression models with neighborhood and half-sibling fixed effects and Gelbach decomposition on 108 Demographic and Health Surveys from 37 sub-Saharan African countries. When adjusting for time of birth, twinning, sex, and survey, a single z-score (6.5 cm) increase in mother's height was associated with a 22% reduction in the average deficit in height-for-age among children under five (according to the WHO 2006 growth standard), 16% lower neonatal mortality (age <1 month) , 10% lower postneonatal mortality (age 1-11 months), 11% lower child mortality (age 12-59 months) , and 2% increase in school attendance among 7-16-year-olds. Adjusting further for maternal education, household living standards, maternal fertility and birth related factors, and neighborhood reduced the coefficients for maternal height by 22% for child height-for-age, 26% for neonatal mortality, 46% for postneonatal mortality, 56% for child mortality, and 90% for school attendance. The decomposition showed that adjusting for neighborhood had a substantial impact on the association of maternal height with all outcomes, especially child mortality. Adjusting for unobserved father and household factors also had a particularly large impact on the association with child mortality. The robustness of the relationship with neonatal mortality suggests that pregnancy and perinatal factors are an important link between maternal height and child outcomes. Adult living standards and socioeconomic and related behavioral factors likely play a small role. Genetics may also play a large role in linking maternal height and child height-for-age, especially for educated mothers, whose height was presumably impacted less by early life adversity
