What is Patterns of Growth in Childhood in Relation to Adult Schooling Attainment and Intelligence Quotient in 6 Birth Cohorts in Low- and Middle-Income Countries: Evidence from the Consortium of Health-Oriented Research in Transitioning Societies (COHORTS) about?

## Background: Growth faltering has been associated with poor intellectual performance. the relative strengths of associations between growth in early and in later childhood remain underexplored. ## Objectives: We examined the association between growth in childhood and adult human capital in 5 low- and middle-income countries (lmics). ## Methods: We analyzed data from 9503 participants in 6 prospective birth cohorts from 5 lmics (brazil, guatemala, india, the philippines, and south africa). we used linear and quasi-poisson regression models to assess the associations between measures of height and relative weight at 4 age intervals [birth, age ∼2 y, midchildhood (mc), adulthood] and 2 dimensions of adult human capital [schooling attainment and intelligence quotient (iq)]. ## Results: Meta-analysis of site- and sex-specific estimates showed statistically significant associations between size at birth and height at ∼2 y and the 2 outcomes (p < 0.001). weight and length at birth and linear growth from birth to ∼2 y of age (1 z-score difference) were positively associated with schooling attainment (β: 0.13; 95% ci: 0.08, 0.19, β: 0.17; 95% ci: 0.07, 0.32, and β: 0.25, 95% ci: 0.10, 0.
