Stunting and academic achievement among Vietnamese children: new evidence from the young lives survey

Most of the empirical literature on the relationship between the health condition and skill development of school children are based on a static relationship between health and skill development. This article contributes to the literature by examining the dynamic relationship between stunting and school achievement using data from the first three waves of the Young Lives Survey in Vietnam. Using both structural equation and hybrid estimators, empirical results show that past school performance is the most significant predictor of the academic performance. Stunting has a significant negative effect on school performance, and its effect in the long run is as twice as much its effect in the short run. The empirical evidence also shows that the age of the child, mothers’ literacy, access to electricity and household consumption significantly affect school performance.
