Out of this figure, half was contributed by mothers aged between 15 and 24, and the other half by mothers aged between 25 and 29 (Iran, Civil Registration Organization, 2010). Considerable health risks are associated with unintended pregnancy and clandestine abortion where there are no routine pre- or post-abortion health-care services (Hosseini-Chavoshi and others, 2012). Among teenage women in developing countries, health risks associated with unintended pregnancy include higher rates of anaemia, pre-term labour and low birth weight (P£rez-Lopez, 2011). Moreover, in the event of an unwanted pregnancy being carried to term, the risks to the child include stillbirth, low birth weight, mental and physical dysfunction, or neonatal death due to neglect (Marston and Cleland, 2003a).
