(P78) RECEIPT OF CONTRACEPTIVE AND SEXUALLY TRANSMITTED INFECTION SERVICES AMONG SEXUALLY ACTIVE NON-PREGNANT ADOLESCENT AND YOUNG ADULT FEMALES — NATIONAL SURVEY OF FAMILY GROWTH, UNITED STATES, 2011-2013, 2013-2015, 2015-2017, AND 2017-2019

Background:
Examine contraceptive and sexually transmitted infection (STI) services received over time and by other characteristics among adolescent and young adult (AYA) females.

Methods:
We analyzed National Survey of Family Growth data (2011-2013, 2013-2015, 2015-2017, and 2017-2019) to identify sexually active, non-pregnant 15–24-year-old females. Weighted prevalence estimates and 95% confidence intervals (CI) of receipt of contraceptive or STI services in the past 12 months were calculated for 15-19 and 20–24-year-olds. Trends were examined using linear regression. Estimates stratified by other characteristics were restricted to 2017-2019 data. Estimates were considered significantly different with Chi-squared P-values≤0.05 and non-overlapping CIs.

Results:
No significant trends in receipt of contraceptive services or STI services were found for either age group. In 2017-2019, among 15-19-year-olds, receipt of contraceptive services was 68.4%(60.4-75.4) and differed by race/ethnicity (non-Hispanic White 77.3%[64.2-86.6], Hispanic 43.6%[31.8-56.2]), number of sexual partners (1 partner 60.5%[49.6-70.5], ≥2 partners 83.0%[73.9-89.3]) and parent/guardian communication about contraception (yes 76.5%[69.0-82.6]), no (53.3%[39.0-67.0]). Receipt of STI services was 61.0%(52.1-69.2) and differed by number of sexual partners (1 partner 52.2%[41.3-62.9], ≥2 partners 77.1%[66.4-85.2]) and previous pregnancy (yes 87.4%[75.7-94.0], no 58.7%[49.2-67.6]). Contraceptive counseling (subset of contraceptive services) and STI testing (subset of STI services) prevalence were 36.0%(29.4-43.2)and 38.5%(31.5-46.1), respectively.  Among 20–24-year-olds, receipt of contraceptive services was 64.8%(58.1-70.9) and STI services was 63.5%(56.0-70.4). STI services differed by number of sexual partners (1 partner 58.2%[49.3-66.5], ≥2 partners 78.7%[66.8-87.1]) and parent/guardian communication about: abstinence (yes 72.0%[63.1-79.5], no 53.5%[43.7-63.0]), STIs (yes 72.8%[64.1-80.1], no 51.5%[41.8-61.2]), and any topic (abstinence, contraception, or STIs) (yes 68.9%[60.5-76.3], no 49.6%[39.2-60.1]). Contraceptive counseling and STI testing prevalence were 31.8%(26.3-37.8) and 52.7%(45.6-59.8), respectively.

Conclusion:
Prevalence of contraceptive services and STI services have remained stable from 2011-2013 to 2017-2019 in AYA females. Low prevalence of contraceptive counseling and STI testing suggests missed opportunities to improve equitable access to recommended services.
