The findings from the study indicate that continuous practice of early girl-child marriage is caused by a number of factors which include poverty, ignorance from parents, traditional practice, peer pressure, family alliances to mention a few. While social insecurity, strain on the health sector, high level of illiteracy, increased mortality rates as well as high level of divorce rates have been established as some of the impacts of early girl child marriages on the society.
