Compared with teenagers in the 1980s and 1990s, teens who were ages 15-19 during 2011-2013 were less likely to start having sex, and when they did initiate intercourse, they were more likely to use contraceptives than the previous generations, according to results from a CDC study.

Data from the National Survey of Family Growth, taken in 1988, 1995, 2002, and from 2006-2010 and 2011-2013, revealed that the rate of teenagers engaging in sexual activity has declined steadily, according to , and , of the CDC's National Center for Health Statistics, in Hyattsville, Md. In 1988, 51% of girls and 60% of boys were starting to have sex, but from 2006-2010 those numbers fell to 43% of girls and 42% of boys.

The self-report surveys were taken from 1,037 female and 1,088 male teens, ages 15-19, and an additional 960 females and 810 males ages 20-24 who were asked to recall their sexual activity when they were teenagers.

Little changed for girls in the subsequent group, as 44% of girls from the 2011-2013 survey said they'd started having sex, but a slight uptick was seen among boys at 47%.

In their younger years, ages 15 and 16, boys were more likely to have engaged in sexual activity than girls (18% versus 13%). But by the time they reached 17, the rates of having had intercourse leveled out between genders (44% of boys versus 43% of girls).

More so than girls, boys in the 2011-2013 group were more likely to use contraception the first time they had sex (84% versus 79%). This gender trend persisted when stratified by age; 93% of girls, and 99% of boys, who were 18 or 19 when they first started having sex used a method of contraception compared to 77% of girls and 82% of boys who were 17 at sexual initiation.

The researchers included the withdrawal method as a form of birth control in their analysis.

In the 2011-2013 group, 97% of girls who were sexually active said that they had used a condom at least once, 60% said they had used withdrawal, a 5% increase over girls in 2002, and 54% reported using the pill, a 6% decrease over girls in 2002.

The fertility awareness method was used by 15% of girls in both the 2006-2010 and 2011-2013 groups, a 4% increase over 2002. The ring remained in steady use at 5% for both the 2006-2010 and 2011-2013 groups, as did the intrauterine device at 3% across the years.

The patch was only used by 2% in 2002, then jumped to 10% for the 2006-2010 group, and fell back to 2% for the 2011-2013 group.

Implants were used by 1% in the 2006-2010 group and 2% in the 2011-2013 group.

The most notable change in contraceptive methods among girls was a 14% increase in the use of emergency contraception (8% versus 22%) from 2002 to 2011-2013, and a 6% decrease in the use of Depo-Provera over the same period.

Girls who did not use some form of protection at first intercourse were more likely to have a baby than those who did, especially in the younger girls. For example, 17-year old girls were five times more likely (11% versus 2%), and 18-year old girls were three times more likely (17% versus 5%), but then 19-year old girls were only two times more likely (26% versus 10%) to have a baby if they didn't use contraception at first encounter compared with girls of the same age who did.
