a. Reference group is women with uncomplicated deliveries.

b. Model 1: delivery status plus potential confounding factors.

c. Model 2: Model 1 plus unpaid hospital debts at 6 or 12 months postpartum.

d. Model 3: Model 2 plus self-reported serious illness at 6 or 12 months postpartum.

e. Model 4: Model 3 plus new spousal abuse in the first 6 months postpartum.

f. Adjusted for 6 month depressive group (K10≥14), parity, marital status, wealth quintile and hospital of recruitment.
