“…As such, first sex remains a major social problem and a serious public health issue (Clark, 2004;Cleland, Boerma, Carael, & Weir, 2004;Gage, 1998;Kuate Defo, 1998a). Whereas age at first sex is almost stalling, recent estimates indicate that age at marriage is increasing (Mensch, Grant, & Blanc, 2006), yielding a lag of 2 years for women (Adair, 2008) and up to 8 years for men (Bankole, Singh, Woog, & Wulf, 2004) between sexual onset and first marriage. This is likely to be detrimental for youth, especially in a context of low levels of condom use and contraception.…”
