Final answer:
It is true that abstinence-only sex education programs had little to no impact on reducing adolescent sexual activity, with some studies suggesting they may even increase teen pregnancy rates. Comprehensive sex education is favored for its effectiveness in reducing unintended pregnancies and STIs.
Step-by-step explanation:
The claim that abstinence-only sex education programs had little to no impact on reducing adolescent sexual activity is True. Studies and surveys have indicated that comprehensive sex education, which includes information on safer sexual practices and contraception, is largely favored by the public and is considered more effective in terms of reducing unintended pregnancies and sexually transmitted infections (STIs). A study in the journal PLoS One found that abstinence-only education may in fact increase teen pregnancy rates. Meanwhile, the majority of U.S. adults, as well as teenagers, acknowledge the importance of realistic approaches to sex education over the idealized concept of abstinence until marriage.
