A study of the cost effectiveness of CSE highlights the potential cost savings of rolling out a national, mandatory sexuality education programme.
In Estonia, a mandatory programme was rolled out for 7–16 year olds, alongside youth-friendly sexual and reproductive health services.
The cost of rolling out the programme was $5.6 million. Between 2001 and 2009, an estimated 13,490 negative health outcomes were prevented, including 4,280 unintended pregnancies, 7,240 incidences of STI transmission and 1,970 HIV infections.
In a cost–benefit analysis, based on HIV infections prevented and on HIV treatment costs alone, sexuality education would only have to be responsible for 4 per cent of all HIV infections averted to be considered as not only a costeffective intervention but a cost-saving one too.
