Appropriate VAS uptake per age schedules was 62.4% among the children. Predicted probabilities (Pr) of age with appropriate VAS uptake significantly decreased among older children, 6-11 months (Pr=0.95, 95%CI: 0.90-0.99), 12-23 months (Pr=0.76, 95%CI:0.69-0.84), 24-35 months (Pr=0.59, 95%CI: 0.50-0.68), 36-47 months (Pr=0.42, 95%CI:0.33-0.52), 48-59 months (Pr=0.30, 95%CI:0.19-0.40) accordingly. Reduced age of children (AOR=8.06, 95%CI: 3.96-16.43), Caregiver's level of education; senior high school education (AOR=0.30, 95%CI:0.13-0.69), tertiary education (AOR=3.25, 95%CI:1.06-10.01) and good knowledge on VAS schedules (AOR=4.65, 95%CI:1.4-15.1) were associated with increased odds of VAS uptake.
