^aModel 1 included three HAZ measures as independent variables, adjusted for each other.

^bModel 2 further adjusted for gender, gestational duration, wealth index, father's occupation, father's literacy and mother's literacy.

^cModel 3 further adjusted for completed years of school education.

^dHAZ = height‐for‐age z‐score at one and 24‐months‐of‐age and 15‐years‐of‐age (180 months).
