WHAT'S KNOWN ON THIS SUBJECT: Sending and receiving sexually explicit picture and text messages via cell phone (ie, "sexting") among adolescents is publicized as a societal and public health concern, yet it is unknown whether sexting is associated with physical sexual activity or sexual risk behavior. WHAT THIS STUDY ADDS:This study is the first to examine sexting among a probability sample of adolescents and found that sexting is associated with sexual activity, sexual risk behavior, and knowing other person(s) who have sent a sext. abstract OBJECTIVES: Sexting (sending/receiving sexually explicit texts and images via cell phone) may be associated with sexual health consequences among adolescents. However, to date, no published data from a probability-based sample has examined associations between sexting and sexual activity.METHODS: A probability sample of 1839 students was collected alongside the 2011 Youth Risk Behavior Survey in Los Angeles high schools. Logistic regressions were used to assess the correlates of sexting behavior and associations between sexting and sexual risk-taking. RESULTS:Fifteen percent of adolescents with cell phone access reported sexting, and 54% reported knowing someone who had sent a sext. Adolescents whose peers sexted were more likely to sext themselves (odds ratio [OR] = 16.87, 95% confidence interval [CI]: 9.62-29.59). Adolescents who themselves sexted were more likely to report being sexually active (OR = 7.17, 95% CI: 5.01-10.25). Nonheterosexual students were more likely to report sexting (OR = 2.74, 95% CI: 1.86-4.04), sexual activity (OR = 1.52, 95% CI: 1.07-2.15), and unprotected sex at last sexual encounter (OR = 1.84, 95% CI: 1.17-2.89).CONCLUSIONS: Sexting, rather than functioning as an alternative to "real world" sexual risk behavior, appears to be part of a cluster of risky sexual behaviors among adolescents. We recommend that clinicians discuss sexting as an adolescent-friendly way of engaging patients in conversations about sexual activity, prevention of sexually transmitted infections, and unwanted pregnancy. We further recommend that discussion about sexting and its associated risk behavior be included in school-based sexual health curricula.

OBJECTIVE: It is unknown if “sexting” (ie, sending/receiving sexually explicit cell phone text or picture messages) is associated with sexual activity and sexual risk behavior among early adolescents, as has been found for high school students. To date, no published data have examined these relationships exclusively among a probability sample of middle school students. METHODS: A probability sample of 1285 students was collected alongside the 2012 Youth Risk Behavior Survey in Los Angeles middle schools. Logistic regressions assessed the correlates of sexting behavior and associations between sexting and sexual activity and risk behavior (ie, unprotected sex). RESULTS: Twenty percent of students with text-capable cell phone access reported receiving a sext and 5% reported sending a sext. Students who text at least 100 times per day were more likely to report both receiving (odds ratio [OR]: 2.4) and sending (OR: 4.5) sexts and to be sexually active (OR: 4.1). Students who sent sexts (OR: 3.2) and students who received sexts (OR: 7.0) were more likely to report sexual activity. Compared with not being sexually active, excessive texting and receiving sexts were associated with both unprotected sex (ORs: 4.7 and 12.1, respectively) and with condom use (ORs: 3.7 and 5.5, respectively). CONCLUSIONS: Because early sexual debut is correlated with higher rates of sexually transmitted infections and teen pregnancies, pediatricians should discuss sexting with young adolescents because this may facilitate conversations about sexually transmitted infection and pregnancy prevention. Sexting and associated risks should be considered for inclusion in middle school sex education curricula.

We investigated PrEP uptake, adherence, and discontinuation among young app-using MSM in California (N=761). 9.7% of participants had ever used PrEP; 87% of those deemed good candidates for screening (indicated by a CDC risk index score ≥10) were not current or past users. PrEP use was associated with higher income (aOR:4.13; CI:1.87-9.12), receptive condomless anal sex(aOR:3.41; CI:1.71-6.78), HIV-positive sex partners (aOR:2.87; CI:1.53-5.38), popper use (aOR:3.47; CI:1.96-6.13), and recent STI diagnosis (aOR:2.90; CI:1.64-5.13). 41.5% of users wanted help remembering to take PrEP. The top reason for discontinuation was concern about long-term side effects (33.0%). YMSM app users are prime candidates for PrEP, despite low uptake. Apps may be useful tools for PrEP information dissemination, adherence monitoring, and support.

Cyberbullying interventions should account for gender and sexual identity, as well as the possible benefits of educational interventions for intensive Internet users and frequent texters.
