  • Assessment

    Please answer the following questions based on what you learned in this activity.
  • Congratulations. The best choice is C. In the 2021 PrEP guidelines, the CDC recommends that clinicians should discuss sexual health needs broadly with patients including all age groups, both sexes, all genders, and both married and unmarried persons. The clinician can explain that taking a brief sexual history is routine practice for all patients in order to provide individually appropriate sexual health care.

  • Congratulations. The best answer is A. LEN use in pregnancy is supported by several agencies or guidelines. In the PURPOSE1 trial, lenacapavir was found to be present in breastmilk (median milk-to-plasma ratio: 0.63 [n=8 matched pairs]); LEN exposure in infant plasma was low (median breastfed-infant-to-mother plasma ratio: 0.05 [n=11 matched pairs]). Also in the trial, participants who became pregnant could opt to re-consent and remain on randomized study drug or receive open-label TDF/FTC. Predicted lenacapavir exposure was not statistically significantly different by pregnancy trimester or postpartum status compared with non-pregnant/lactating participants.

  • Congratulations. The best answer is B. Analysis of the Kaiser Permanente Northern California PrEP cohort revealed that young adults (ages 18-25) were a group with lower PrEP persistence. And while PrEP initiations for young adults increased between 2016-2023, the persistence rate decreased, particularly among ages 18-21. Answers A, C, and D are not specific factors for lower PrEP persistence.
