  1. Notes: Robust standard errors in parenthesis, **p < 0.01, *p < 0.05, + p < 0.1
  2. The dependent variable is weight-for-height zscore. Estimated treatment effects from regressions using the full sample, 2007–2009, 2010–2012 and 2013–2015 birth cohorts presented. The treatment variable (Trt) is a dummy equal to one if the child had access to the midday meals program. Panel A provides results for the IV-Random Effects model and Panel B provides results for GLS-Random Effects Model. Other controls include child age, age squared, gender, zscore of first weight, zscore of birthweight, zscore of first height, pcare, ethnicity, CDC status and birth-year fixed effects either as direct controls or instruments
