    (Wolters Kluwer, 2016-02) He, Fei; Hensel, Devon J.; Harezlak, Jaroslaw; Fortenberry, J. Dennis; Department of Biostatistics, Richard M. Fairbanks School of Public Health
    STUDY OBJECTIVE: To assess condom use as a function of number of coital events in newly formed sexual relationships. METHODS: Participants who reported at least one new partner during the 12-week study interval (n = 115; ages 18-29 years; 48% women; 90% African American) completed weekly sexually transmitted infections testing and 3 times daily electronic diary collection assessing individual and partner-specific affect, daily activities, sexual behavior, and condom use. We analyzed event-level condom use percentage and participant-level behavior response effects. generalized additive mixed models were used to estimate condom use probability accounting for within-partner and within-participant correlations via random effects. RESULTS: The average condom use probability at the first coital event in new relationships was 55% for men and 36% for women. Analyses showed that smooth shapes of estimated condom use probabilities were similar for both sexes and were fitted using generalized additive mixed models. Relatively higher condom use percentage was followed by a sharp decline during the first 9 coital events decreasing to 16% for men and 8% for women. More rapid decline in condom use among women was highly associated with higher levels of relationship and sexual satisfaction. CONCLUSIONS: The likelihood of condom use declines sharply for both men and women after the early accrual experience with a partner. Relationship and sexual satisfaction also influence declines in condom use, especially among women.

    Differences in risk behaviours, HIV/STI testing and HIV/STI prevalence between men who have sex with men and men who have sex with both men and women in China
    (SAGE, 2016-09) Davis, Alissa; Best, John; Luo, Juhua; Van Der Pol, Barbara; Dodge, Brian; Meyerson, Beth; Aalsma, Matthew; Wei, Chongyi; Tucker, Joseph D.; Department of Epidemiology, Richard M. Fairbanks School of Public Health
    Differences in risk behaviours between men who have sex with men (MSM) and men who have sex with both men and women (MSMW) have important implications for HIV and sexually transmitted infection (STI) transmission. We examined differences in risk behaviours, HIV/STI testing, self-reported HIV/STI diagnoses, and linkage to HIV care between MSM and MSMW across China. Participants were recruited through three MSM-focused websites in China. An online survey containing items on socio-demographics, risk behaviours, testing history, self-reported HIV/STI diagnosis, and linkage to and retention in HIV care was completed from September to October 2014. Chi square tests and logistic regression analyses were conducted. MSMW were less likely to use a condom during last anal sex (p ≤ 0.01) and more likely to engage in group sex (p ≤ 0.01) and transactional sex (p ≤ 0.01) compared to MSM. Self-reported HIV/STI testing and positivity rates between MSM and MSMW were similar. Among HIV-infected MSM, there was no difference in rates of linkage to or retention in antiretroviral therapy when comparing MSM and MSMW. Chinese MSM and MSMW may benefit from different HIV and STI intervention and prevention strategies. Achieving a successful decrease in HIV/STI epidemics among Chinese MSM and MSMW will depend on the ability of targeted and culturally congruent HIV/STI control programmes to facilitate a reduction in risk behaviours.

    Dual method use among long-acting reversible contraceptive users
    (Taylor & Francis, 2018-04) Bernard, Caitlin; Zhao, Qiuhong; Peipert, Jeffrey F.; Obstetrics and Gynecology, School of Medicine
    OBJECTIVE: To compare rates of dual method use (concurrent use of condoms and an effective method of contraception) in long-acting reversible contraceptive (LARC) and non-LARC hormonal contraceptive users, and to determine factors associated with dual method use. METHODS: We conducted a secondary analysis of the Contraceptive CHOICE Project, an observational, prospective cohort study of 9256 women in St. Louis, MO, USA. Our sample included 6744 women who initiated a contraceptive method within 3 months of enrollment, continued use at 6 months post-enrollment, and responded regarding dual method use. Our primary outcome was the rate of dual method use at 6 months post-enrollment. RESULTS: Dual method use was reported by 32% of LARC and 45% of non-LARC hormonal contraceptive users (p < .01). After adjusting for other covariates and comparing to non-LARC hormonal contraceptive users, LARC users were less likely to report dual method use (RRadj 0.76, 95% CI 0.70-0.83). Factors associated with dual method use in our multivariable analysis were age <25 years, black race, lower education, single relationship status, baseline dual method use, baseline diagnosis of sexually transmitted infection (STI), greater partner willingness to use a condom, and higher condom self-efficacy score. CONCLUSIONS: LARC users are less likely to report dual method use compared to non-LARC hormonal contraceptive users, but other factors also impact dual method use. Further studies should be performed to determine whether this lower dual method use increases the risk of STI.

    Porn Sex versus Real Sex: Sexual Behaviors Reported by a U.S. Probability Survey Compared to Depictions of Sex in Mainstream Internet-Based Male-Female Pornography
    (Springer Nature, 2022) Fritz, Niki; Malic, Vinny; Fu, Tsung‑chieh; Paul, Bryant; Zhou, Yanyan; Dodge, Brian; Fortenberry, J. Dennis; Herbenick, Debby; Medicine, School of Medicine
    Using data from a 2014 U.S. nationally representative probability survey and a 2014 content analysis of 2562 male-female videos from two popular pornographic websites, this study aimed to: (1) compare the prevalence of survey respondents' event-level sexual behaviors with those depicted in mainstream pornography online videos; (2) compare event-level condom use with condom use prevalence in pornographic videos; (3) compare event-level orgasm with prevalence of orgasms in pornographic videos; and (4) assess whether respondents' partnered use of pornography was associated with the sexual behaviors in which they report engaging. We found that kissing, male orgasm, female orgasm, and condom use were significantly less prevalent in the pornographic videos than in survey respondents' most recent sexual experiences. Conversely, penile-anal intercourse and fellatio were significantly more prevalent in the pornographic videos than in participants' reports of their most recent sexual experience. There were no significant differences between the prevalence of cunnilingus or sex toy use represented in the videos as compared to survey respondents' reports. Finally, we found that individuals who reported partnered pornography use during their most recent sexual experience were more likely to report having engaged in oral sex, penile-anal intercourse, and sex toy use and were also more likely to report female orgasm during their most recent sexual experience.

    Relationships between Penile-Vaginal Intercourse Frequency and Condom/Contraceptive Use from 2009 to 2018: Findings from the National Survey of Sexual Health and Behavior
    (Taylor & Francis, 2022) Fu, Tsung-Chieh; Rosenberg, Molly; Golzarri-Arroyo, Lilian; Fortenberry, J. Dennis; Herbenick, Debby; Pediatrics, School of Medicine
    Objectives: To examine changes over time in event-level condom/contraceptive use and the association between past year penile-vaginal intercourse frequency and event-level condom/contraceptive use. Methods: Data were from the 2009 and 2018 National Survey of Sexual Health and Behavior, an online probability survey of U.S. adolescents and adults. Results: Use of condoms and highly effective hormonal contraceptives decreased while long-acting reversible contraceptive use increased from 2009 to 2018 among adults. Increased penile-vaginal intercourse frequency was associated with decreased use of most contraceptive methods but an increase in condom use for adolescents. Conclusions: Sexual frequency should be considered when assessing condom/contraceptive use.

    The International Sexual Health And REproductive Health during COVID-19 (I-SHARE) Study: A Multicountry Analysis of Adults from 30 Countries Prior to and During the Initial Coronavirus Disease 2019 Wave
    (Oxford University Press, 2022) Toller Erausquin, Jennifer; Tan, Rayner K.J.; Uhlich, Maximiliane; Francis, Joel M.; Kumar, Navin; Campbell, Linda; Zhang, Wei Hong; Hlatshwako, Takhona G.; Kosana, Priya; Shah, Sonam; Brenner, Erica M.; Remmerie, Lore; Mussa, Aamirah; Klapilova, Katerina; Mark, Kristen; Perotta, Gabriela; Gabster, Amanda; Wouters, Edwin; Burns, Sharyn; Hendriks, Jacqueline; Hensel, Devon J.; Shamu, Simukai; Strizzi, Jenna Marie; Esho, Tammary; Morroni, Chelsea; Eleuteri, Stefano; Sahril, Norhafiza; Low, Wah Yun; Plasilova, Leona; Lazdane, Gunta; Marks, Michael; Olumide, Adesola; Abdelhamed, Amr; López Gómez, Alejandra; Michielsen, Kristien; Moreau, Caroline; Tucker, Joseph D.; International Sexual Health And REproductive Health during COVID-19 Research Consortium; Pediatrics, School of Medicine
    Background: There is limited evidence to date about changes to sexual and reproductive health (SRH) during the initial wave of coronavirus disease 2019 (COVID-19). To address this gap, our team organized a multicountry, cross-sectional online survey as part of a global consortium. Methods: Consortium research teams conducted online surveys in 30 countries. Sampling methods included convenience, online panels, and population-representative. Primary outcomes included sexual behaviors, partner violence, and SRH service use, and we compared 3 months prior to and during policy measures to mitigate COVID-19. We conducted meta-analyses for primary outcomes and graded the certainty of the evidence. Results: Among 4546 respondents with casual partners, condom use stayed the same for 3374 (74.4%), and 640 (14.1%) reported a decline. Fewer respondents reported physical or sexual partner violence during COVID-19 measures (1063 of 15 144, 7.0%) compared to before COVID-19 measures (1469 of 15 887, 9.3%). COVID-19 measures impeded access to condoms (933 of 10 790, 8.7%), contraceptives (610 of 8175, 7.5%), and human immunodeficiency virus/sexually transmitted infection (HIV/STI) testing (750 of 1965, 30.7%). Pooled estimates from meta-analysis indicate that during COVID-19 measures, 32.3% (95% confidence interval [CI], 23.9%-42.1%) of people needing HIV/STI testing had hindered access, 4.4% (95% CI, 3.4%-5.4%) experienced partner violence, and 5.8% (95% CI, 5.4%-8.2%) decreased casual partner condom use (moderate certainty of evidence for each outcome). Meta-analysis findings were robust in sensitivity analyses that examined country income level, sample size, and sampling strategy. Conclusions: Open science methods are feasible to organize research studies as part of emergency responses. The initial COVID-19 wave impacted SRH behaviors and access to services across diverse global settings.
