used to describe a policy or a type of education that teaches people that they should not have sex outside of marriage, and does not teach about any other methods of preventing pregnancy or disease

At my former high school, abstinence-only education was required for all students. 在我以前就读的高中，所有学生都需要接受唯节欲论的性教育。

used to describe a policy of telling people not to use drugs or alcohol at all, rather than trying to reduce the risk in some other way

Their approach to treating people with substance use disorders is quite different from the traditional "abstinence-only" philosophy. 他们治疗药物滥用失常患者的方法与传统的“唯节欲”理念截然不同。
