We calculated adolescent pregnancy rates by single year of age using data from the National Center for Health Statistics, the Guttmacher Institute, and the US Census Bureau.<\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n Sexual activity is and has long been rare among those 12 and younger; most is nonconsensual. By contrast, most older teens (aged 17\u201319) are sexually active. Approximately 30% of those aged 15 to 16 have had sex. Pregnancy rates among the youngest teens are exceedingly low, for example, \u223c1 per 10\u2009000 girls aged 12. Contraceptive uptake among girls as young as 15 is similar to that of their older counterparts, whereas girls who start having sex at 14 or younger are less likely to have used a method at first sex and take longer to begin using contraception.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS:<\/jats:title>\n Sexual activity and pregnancy are rare among the youngest adolescents, whose behavior represents a different public health concern than the broader issue of pregnancies to older teens. Health professionals can improve outcomes for teenagers by recognizing the higher likelihood of nonconsensual sex among younger teens and by teaching and making contraceptive methods available to teen patients before they become sexually active.<\/jats:p>\n <\/jats:sec>","DOI":"10.1542\/peds.2012-3495","type":"journal-article","created":{"date-parts":[[2013,4,2]],"date-time":"2013-04-02T00:29:16Z","timestamp":1364862556000},"page":"886-891","source":"Crossref","is-referenced-by-count":219,"title":["Sexual Initiation, Contraceptive Use, and Pregnancy Among Young Adolescents"],"prefix":"10.1542","volume":"131","author":[{"given":"Lawrence B.","family":"Finer","sequence":"first","affiliation":[{"name":"Research Division, Guttmacher Institute, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse M.","family":"Philbin","sequence":"additional","affiliation":[{"name":"Research Division, Guttmacher Institute, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2013,5,1]]},"reference":[{"key":"2021120900113399800_B1","doi-asserted-by":"crossref","DOI":"10.7208\/chicago\/9780226736204.001.0001","volume-title":"Not Under My Roof: Parents, Teens, and the Culture of Sex","author":"Schalet","year":"2011"},{"key":"2021120900113399800_B2","unstructured":"Kaiser Family Foundation.
