  • *Independent variables adjusted for: place of residence, wealth index, mother's (religion, education, age, body mass index, work status and desire for pregnancy), father's education, child's (sex, birth place, body size, mode of delivery, delivery assistance, birth order and birth interval).

  • †Multiple births were excluded from the analysis; p values based on Cox regression.

  • ‡Caesarean section is a combination of both elective and emergency caesarean—variables that were not statistically significant.
