a programme of education that teaches people that they should not have sex outside of marriage, especially when this is taught instead of other forms of sex education such as teaching about contraception (= methods of preventing pregnancy)

The study has been interpreted as showing that abstinence programmes are failing and that condom use should be encouraged. 该研究被认为是证明了禁欲运动正在失败，应该鼓励使用安全套。
