The prevalence of a wide range of risk-taking behaviour among high-school students in the Cape Peninsula, South Africa, was investigated. In this article, the results for sexual behaviour are presented. Cluster sampling techniques produced a sample of 7,340 students from 16 schools in the three major education departments, of whom 79.7% answered the section dealing with sexual behaviour. A self-administered questionnaire was completed in a normal school period. Estimates for each education department were weighted to produce an overall estimate. Of the sample, 17.4% indicated a previous episode of heterosexual intercourse. The median age at first intercourse was 15.1 years. The median number of partners in the previous 12 months was 1.0. The median number of weeks since the most recent coital episode was 6.6; on this episode 76.6% had known their partners for more than 7 days, while 60.5% had done something to avoid pregnancy. The most frequently used method of contraception was injectable steroids for Xhosa-speaking students and condoms for the other students. Males and Xhosa-speaking students appear to be particularly at risk for the adverse consequences of sexual activity. The HIV epidemic has increased the urgency of introducing meaningful sexuality education in South African schools.
对南非开普半岛高中生中广泛存在的一系列冒险行为的流行情况进行了调查。在本文中，给出了性行为方面的调查结果。采用整群抽样技术从三个主要教育部门的16所学校抽取了7340名学生作为样本，其中79.7%的学生回答了与性行为相关的部分。在正常上课期间完成了一份自填式问卷。对每个教育部门的估计值进行加权以得出总体估计值。在样本中，17.4%的学生表示曾有过异性性交经历。首次性交的中位年龄为15.1岁。过去12个月性伴侣的中位数为1.0。距最近一次性交的中位周数为6.6周；在这次性交中，76.6%的学生认识其性伴侣超过7天，而60.5%的学生采取了某种措施来避免怀孕。最常用的避孕方法是讲科萨语的学生使用注射用类固醇，其他学生使用避孕套。男性和讲科萨语的学生似乎特别容易受到性活动不良后果的影响。艾滋病疫情增加了在南非学校开展有意义的性教育的紧迫性。
