Which interventions are effective in preventing unintended adolescent pregnancy and its antecedent risk behaviors?
Among adolescents, educational interventions increase reported condom use at most recent intercourse (number needed to treat [NNT] = 21; Strength of Recommendation [SOR]: B, based on inconsistent or limited-quality patient-oriented evidence), whereas contraceptive-promoting interventions increase use of hormonal contraception (NNT = 5; SOR: A, based on consistent, good-quality patient-oriented evidence). Combining these interventions lowers the risk of unintended pregnancy compared with existing conventional population-wide activities alone1 (NNT = 25; SOR: B, based on inconsistent or limited-quality patient-oriented evidence).
Unintended adolescent pregnancy is associated with adverse physical and psychological outcomes for mother and child, lower lifelong socioeconomic and educational achievement, and higher medical costs.2 Births among adolescents have been decreasing over time in most countries, including the United States, primarily because of lower rates of sexual activity and higher rates of contraception use.2–4 However, the rate of unintended adolescent pregnancy in the United States is higher than in many
