Children from low socio-economic status (SES) households often demonstrate worse growth and developmental outcomes than wealthier children, in part because poor children face a broader range of risk factors. It is difficult to characterise the trajectories of SES disparities in low- and middle-income countries because longitudinal data are infrequently available.
The authors analyse measures of children’s linear growth (height) at ages 1, 5, 8 and 12 and receptive language (Peabody Picture Vocabulary Test) at ages 5, 8 and 12 in Ethiopia, India, Peru and Vietnam in relation to household SES, measured by parental schooling or household assets. They calculate children’s percentile ranks within the distributions of height-for-age z-scores and of age- and language-standardized receptive vocabulary scores.
Young Lives is an international study of childhood poverty, following the lives of 12,000 children in 4 countries (Ethiopia, India, Peru and Vietnam) over 15 years. Young Lives is funded by the UK Department for International Development
