The objective of this paper was to investigate factors associated with time to first birth after
first marriage among women in Uganda. The assessment was made using data sourced from
the 2011 Uganda Demographic and Health survey. The analysis was done using a time-toevent
approach involving life tables, log-rank and the Cox Proportional Hazards model. In the
results, the median time to first birth after first marriage was 2 years (range, 1-36). The key
predictors of having a live birth after first marriage were loss of a pregnancy either
spontaneously or induced, knowledge of ovulation cycle and late sexual debut (p < 0.05). In
particular, the chances of first birth after first marriage were lower among women who had
ever lost a pregnancy and women having their sexual intercourse at a later age. On the
contrary, the chances of having a first child after marriage were higher among women at
higher ages at first marriage and those who were aware of their ovulation cycle.
