Read the extract below on the 2008 Youth Risk Behaviour Survey: YOUTH RISK BEHAVIOUR SURVEY The youth of South Africa are constantly exposed to risks, which may promote substance use, unprotected sex, unhealthy eating habits and violence. These behaviours that are usually adopted during their youthful years and often persist into adulthood, are interrelated, and in most cases, are preventable. In order to protect the youth from these risk behaviours, it is therefore necessary to educate them at an early age on the dangers and consequences, as well as to foster health promoting behaviours and environments. The Medical Research Council released the results of the 2nd South African National Youth Risk Behaviour Survey 2008 today. This nationally representative survey among 10,270 secondary school learners in grades 8 through 11, reports on the prevalence of behaviours that place them at risk for disease and ill health. The 2008 survey showed significant reductions in risky sexual behaviour. Fewer school learners had ever had sex (from 41% to 38%). Of those who had sex, the number of school learners that had two or more sexual partners in their lifetime significantly reduced (from 45% to 41%), and less learners had one or more sexual partners during the past three months (from 70% to 52%). Also, of those who ever had sex, the incidence of sexually transmitted infections significantly reduced (from 7% to 4%), while consistent condom use increased slightly (29% to 31%), Source: Press Releases United States Diplomatic Mission to South Africa southafrica.usembassy.gov/press 100420.html 2/2 1.5 Analyse the findings and discuss the possible reasons for any observed changes since the 2002 Survey.
