HAZ = Height for Age z-scores. WHZ= Weight for Age z-scores. Wealth index variables was not included in the final model for WHZ; † R2 for adjusted HAZ model: 14.2 %, p-Value of the model: 0.00001; ‡ R2 for adjusted WHZ model: 9.1%, p-Value of the model: 0.00001; a Have Pig, mother education and sanitation facilites were adjusted for region; b Adjusted for all the covariates in the model, Age and Age squared (coefficients not shown).
