Early sexual debut and premarital sex are increasingly common features of female adolescence in Kenya - putting girls at the risk of unwanted pregnancy and even infections such as sexually transmitted infections and HIV/AIDS. Little discussion has also addressed the reasons young girls give for leaving school prematurely. Except in qualitative studies, the simultaneous decisions related to pregnancy and leaving school are rarely examined. In particular, if a girl gives a reason other than pregnancy for discontinuing her education, whether she is also pregnant at the time she leaves school is rarely taken into account. Particularly for those who give such dominant concerns as financial issues, family obligations, or lack of interest in school, a pregnancy may serve as an unacknowledged catalyzing force for timing of school dropout.
