Sexual behaviour and condom use of 15- to 24-year-olds in 2003 and 2009/2010.

Based on data from the 2003 and 2009/2010 Canadian Community Health Survey (CCHS), this article provides current information about the sexual behaviours and condom use of 15- to 24-year-olds and examines changes since 2003. Between 2003 and 2009/2010, the percentage of 15- to 24-year-olds who had had sexual intercourse at least once remained stable, as did the percentages who reported becoming sexually active at an early age and having multiple sexual partners. Condom use increased between 2003 and 2009/2010, particularly among people reporting that they had just one sexual partner.
