Characterizing Event-Driven PrEP Use and Investigating its Association with Experiences of PrEP-Related Barriers Among a US National Sample of PrEP Users.

After a decade of implementation in the US, PrEP uptake remains underutilized by communities that would greatly benefit from it. Event-Driven (ED) PrEP is a potential avenue to increase uptake, however very little is known about its use in the US. We analyzed data derived from Together 5000, an internet-based U.

Contraceptive Use by Women Across Multiple Components of Sexual Orientation: Findings from the 2011-2017 National Survey of Family Growth.

We estimated sexual orientation-related disparities in contraceptive outcomes among women across multiple components of sexual orientation. Using pooled National Survey of Family Growth data, 2011-2017, we performed multivariable logistic and multinomial regression analyses (adjusted for race/ethnicity, age, education, and income) to estimate the independent associations between multiple components of sexual orientation (sexual identity, behavior, and attraction) and two contraceptive outcomes-any contraceptive use and type of method used at last intercourse with a male partner. Women who reported any attraction to females had increased odds of having used any contraceptive method compared with those only attracted to males (adjusted odds ratio [AOR] 1.

Dimensions of Sexual Orientation as Predictors of STI-Related Outcomes Among Women: An Examination of 2011-2017 National Survey of Family Growth Data.

To estimate sexual orientation associated disparities in sexually transmitted infection (STI)-related outcomes across multiple dimensions of sexual orientation. Using pooled 2011-2017 National Survey of Family Growth data ( = 16,854), we performed bivariate and multivariable logistic and multinomial regression analyses to estimate associations between sexual identity, behavior in the past 12 months, and attraction, and past-year STI treatment, receipt of the human papillomavirus (HPV) vaccine, and age at first HPV vaccination in cisgender women. Bisexual-identified women (adjusted odds ratio [AOR] = 1.

Changing Trends in Substance Use and Sexual Risk Disparities among Sexual Minority Women as a Function of Sexual Identity, Behavior, and Attraction: Findings from the National Survey of Family Growth, 2002-2015.

Components of sexual minority (SM) status-including lesbian or bisexual identity, having same-sex partners, or same-sex attraction-individually predict substance use and sexual risk behavior disparities among women. Few studies have measured differing associations by sexual orientation components (identity, behavior, and attraction), particularly over time. Data were drawn from the 2002-2015 National Survey of Family Growth female sample (n = 31,222).

An Evaluation of the Effectiveness of School-Based Breastfeeding Education.

School-based interventions aimed at modifying the knowledge, attitudes, social norms, and intended future practice regarding breastfeeding may be an effective way of improving breastfeeding rates. A systematic review of relevant literature was conducted to identify scientifically rigorous studies on school-based interventions and promotion activities that focus on breastfeeding. Of the 1990 citations reviewed, only 6 empirical articles on school-based interventions to promote breastfeeding were found and these interventions vary greatly in terms of format, duration, outcome measures, and significance of the results.

Use of the Internet and mobile-based "apps" for sex-seeking among men who have sex with men in New York City.

The Internet continues to be a popular venue for men who have sex with men (MSM) to seek sexual partners. Increased sexual risk behavior has been linked to MSM who use the Internet to seek partners. However, there has been little research on how new mobile-based social networking applications ("apps") may affect sex-seeking and sexual risk behaviors of MSM.

Online sex-seeking behaviors of men who have sex with men in New York City.

The ongoing HIV epidemic among men who have sex with men (MSM) in New York City and the increased use of Internet sexual social networking websites by MSM fosters a need to understand the characteristics and sex-related behaviors of this group. The authors conducted an online survey of 195 MSM who use sexual social networking websites in New York City. Demographic characteristics, sexual sensation seeking, and HIV optimism-skepticism were compared among participants reporting sex with and without condom use (safe sex and high-risk sex, respectively) with partners met online.

The NYC Condom: use and acceptability of New York City's branded condom.
