[Insert Table 2 about here]
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).
