<p><strong>STUDY OBJECTIVE: </strong>We sought to investigate the associations between race and/or ethnicity and young women's formal sex education and sex education by parents.</p>

<p><strong>DESIGN, SETTING, AND PARTICIPANTS: </strong>Cross-sectional analysis of a nationally representative sample of 1768 women aged 15-24&nbsp;years who participated in the 2011-2013 National Survey of Family Growth.</p>

<p><strong>INTERVENTIONS AND MAIN OUTCOME MEASURES: </strong>We assessed 6 main outcomes: participants' report of: (1) any formal sex education; (2) formal contraceptive education; (3) formal sexually transmitted infection (STI) education; (4) any sex education by parents; (5) contraceptive education by parents; and (6) STI education by parents. The primary independent variable was self-reported race and/or ethnicity.</p>

<p><strong>RESULTS: </strong>Nearly all of participants (95%) reported any formal sex education, 68% reported formal contraceptive education, and 92% reported formal STI education. Seventy-five percent of participants reported not having any sex education by parents and only 61% and 56% reported contraceptive and STI education by parents, respectively. US-born Hispanic women were more likely than white women to report STI education by parents (adjusted odds ratio&nbsp;=&nbsp;1.87; 95% confidence interval, 1.17-2.99). No other significant racial and/or ethnic differences in sex education were found.</p>

<p><strong>CONCLUSION: </strong>There are few racial and/or ethnic differences in formal sex education and sex education by parents among young women.</p>
