Tables 3 and 4 present the results of Heckman’s difference-in-differences estimation. The average treatment effect of the GEHIP’s community-based healthcare program on adverse pregnancy outcome is shown by the interaction term. The results show GEHIP intervention has a statistically significant reduction effect on pregnancy outcome (DiD= -0.043; p-value= 0.010).
Covariates significantly associated with pregnancy outcomes are maternal age, marital status and parity. Teenage mothers were significantly less likely to have adverse pregnancy outcomes compared to older mothers (OR=1.13, p-value<0.001). Married women were significantly less likely to experience adverse pregnancy outcomes compared to single mothers (OR=0.94, p-value=0.003). Higher parity mothers were significantly less likely to have an adverse pregnancy outcome compared to lower parity mothers (OR 0.94, P-value<0.001).
