Globally, each year around 16 million girls aged 15-19 give birth, accounting for aroundrn11 percent of all births. The main objective of this study was to identify predictors ofrnteenage birth and examine the trend of teenage birth based on data from the three EDHrnsurveys (2000, 2005, and 2011 EDHS). Discrete-time hazard modeling was used tornestimate the hazard of first birth before age 20 after controlling the effects of socioeconomicrnfactors. The results suggested that the overall likelihood of first birth beforernage 20 among Ethiopian women increased slightly over time in the three EDH surveys.rnAt the individual level, women's education, especially secondary and higher educationalrnlevel, had the strongest effect to delay first birth during adolescence in the three surveys.rnResiding in urban areas was also inversely associated with teenage birth. Having mediarnexposure had a significant delaying influence, but the effect was low in the 2011 EDHSrndata. These findings reinforce our understanding that the government should continue itsrnefforts to promote female education, especially higher education.
