BackgroundEthiopia has the highest neonatal tetanus mortality and morbidity rates in the world due to low TT immunization coverage coupled with the high amount of deliveries taking place at home. This study aimed to identify individual and community-level factors associated with protections of last live birth against neonatal tetanus among mothers age 15–49 in Ethiopia.MethodsThe P-value of less than 0.05 in the final model was considered as statistically significant. The interclass correlation coefficient and proportional change in variance were used to quantify the magnitude of the general contextual effect. The relative goodness-of-fit test was conducted using Akaike's information criterion.ResultHome delivery (AOR = 0.83; 95% CI: 0.72, 0.96), at least one ANC visits (AOR = 12.35; 95% CI: 10.42, 14.62) and wealth index (poorer (AOR = 1.27, 95% CI: 1.04, 1.54) and richer (AOR = 1.53, 95% CI: 1.21, 1.93). were the individual factors that had an association with the utilization of protection of last live birth against neonatal tetanus.ConclusionsUtilization of protection of last live birth against neonatal tetanus is affected both by the individual and community level factors with high state variation.
