Both models (1) and (2) show a very strong influence of birth order on birth
weight even after adjusting for mother and other child factors. In summary,
from model (1) higher birth weight is associated with higher birth order, being
male, not being a twin, lower mother’s age at first birth, rural residence, and
mother ever having been in union. Mother’s smoking status, wealth quintiles
do not appear to be associated with birth weight, while the results for
education are rather bizarre.
