Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - Sexual activity is common among adolescents. A large ongoing national survey of US high school students reported that 24% of adolescents have had sexual intercourse by ninth grade and 58.1% by 12th grade, based on data collected in 2014 to 2015. Although rates of sexual activity have slowly decreased during 1991 to 2015, the adolescent age group continues to be at the highest risk for common sexually transmitted infections (STIs) compared to other age groups.
