American teenagers receive less formal sex education today than they did 25 years ago, with “troubling” racial inequities that leave youth of color and queer youth at greater risk than other teens for sexually transmitted diseases and unintended pregnancy, according to a new study.
“Many adolescents do not receive any instruction on essential topics or do not receive this instruction until after the first sex,” wrote Laura D. Lindberg, PhD, and Leslie M. Kantor, PhD, MPH, from the Guttmacher Institute, New York, and the department of urban-global public health at Rutgers University, Piscataway, N.J., respectively. “These gaps in sex education in the U.S. are uneven, and gender, racial, and other disparities are widespread,” they added, calling for “robust efforts ... to ensure equity and reduce health disparities.”
The study used cross-sectional data from the 2011-2015 and 2015-2019 National Surveys of Family Growth (NSFG) to examine content, timing, and location of formal sex education among 15- to 19-year-olds in the United States. The data came from samples of 2,047 females and 2,087 males in 2011-2015, and 1,894 females and 1,918 males in 2015-2019. The majority of respondents were aged 15-17 years and non-Hispanic White, with another quarter being Hispanic, and 14% Black.
The survey asked respondents whether, before they turned 18, they had ever received formal instruction at school, church, a community center, “or some other place” about how to say no to sex, methods of birth control, STDs, how to prevent HIV/AIDS, abstaining until marriage to have sex, where to get birth control, and how to use a condom.
Follow-up questions asked about what grade instruction was first received and whether it had occurred before first penile-vaginal intercourse. The 2015-2019 survey also asked about the location of instruction, but only concerning methods of birth control and abstinence until marriage.
The results showed that HIV and STD prevention was the most commonly reported area of instruction, received by more than 90% of both males and females. However, beyond this there were imbalances, with only about half (49%-55%) of respondents receiving instruction meeting the Surgeon General’s Healthy People 2030 composite sex education goal. Lack of instruction on birth control drove this result for 80% of respondents. Specifically, there was a strong slant emphasizing abstinence over birth control instruction. Over both survey periods and both genders, more respondents reported instruction on how to say no to sex (79%-84%) and abstaining until marriage (58%-73%), compared with where to obtain birth control (40%-53%) or how to use a condom (54%-60%). “Overall, about 20% of adolescents received instruction from multiple sources about waiting until marriage, but only 5%-8% received birth control information from multiple settings,” they reported.
There were racial/ethnic and sexual orientation differences in the scope and balance of instruction reported by teens. Less than half of Black (45%) and Hispanic (47%) males received instruction on the combined Healthy People topics, compared with 57% of White males. Black females were less likely (30%) than White females (45%) to receive information on where to get birth control before the first sex. Nonstraight males were less likely than straight males to receive instruction about STIs or HIV/AIDS (83% vs. 93%).
In addition, religious attendance emerged as a key factor in the receipt of sex education, “with more frequent religious attendance associated with a greater likelihood of instruction about delaying sex and less likelihood of instruction about contraception,” the authors noted.
Comparing their findings to previous NSFG surveys, the researchers commented that “the share of adolescents receiving instruction about birth control was higher in 1995 than in 2015-2019 for both the genders; in 1995, 87% of females and 81% of males reported sex education about birth control methods, compared with 64% and 63% in 2015-2019, respectively.” The findings “should spur policy makers at the national, state, and local levels to ensure the broader provision of sex education and that school districts serving young people of color are the focus of additional efforts and funding.”
Asked for comment, John Santelli, MD, MPH, professor of population and family health and pediatrics at Columbia University, New York, who was not involved with the study, said the findings fit into a series of studies by Lindberg going back to 1988 showing that receipt of formal sex education before age 18 has declined over time.
“We, the adults, in America can do better by our young people,” he said in an interview. “Adolescents need sex education that is science based, medically accurate, and developmentally appropriate. Many adolescents are not receiving education that the CDC and health professionals recommend including information about where to get birth control, condom skills, and even, how to say no to sex. The neglect of young Black and Hispanic men is very concerning. However, we are not doing a great job in educating most of our adolescents. Health care providers can be influential in speaking with parents about their children’s education about sex. We need to activate parents, health care providers, and members of the faith community to investigate what is happening about sex education in their own communities.”
Dr. Santelli noted that there are multiple ways to strengthen the provision of sex education in the United States. In a recent commentary, he and his coauthors highlighted the National Sex Education Standards (NSES), which, “developed in partnership between sex education organizations and health professionals, provide clear, consistent, and straightforward guidance on the essential content for students in grades K-12.” The NSES were also used in the development of the CDC’s recently released Health Education Curriculum Analysis Tool.
The commentary takes a strong stand against the recently released revised Medical Institute for Sexual Heath K-12 Standards for Optimal Sexual Development, which, compared with the NSES, are “seriously flawed from both scientific and human rights’ perspectives,” they wrote. “States and local communities aiming to improve adolescent sexual and reproductive health and looking for national standards on sex education should adopt the NSES.”
