ABSTRACT

BACKGROUND: With the onset of the COVID-19 pandemic, reported rates of chlamydia and gonorrhea dropped and remained low for several months of 2020 as compared with 2019. Additional data are needed to reveal causes of reported rate changes. Here, we analyze sexually transmitted infection (STI)-related conversations from the online-discussion platform Reddit to gain insight into the role of the pandemic on public experience of STIs in 2020. METHODS: We collected data from Pushshift's and Reddit's application programming interfaces via programs coded in Python. We focused data collection on the "r/STD" subreddit. Collected submissions contained the term(s) "covid" and/or "coronavirus" and were submitted between January 1, 2020, and December 31, 2020. We collected the title and text of each submission. We used a Latent Dirichlet Allocation algorithm to create a topic model of post content and complemented this approach with key term analysis and qualitative hand-coding. RESULTS: Of the 288 posts collected, 148 were complete and included in analyses. Latent Dirichlet Allocation revealed 4 main topics in the collected posts: narration of sexual experiences, STI testing, crowdsourcing of visual STI diagnoses, and descriptions of STI-related pains and treatments. Hand-coding of COVID-19 mentions revealed pandemic-related anxieties about STI care seeking and experienced delays in and changes to quality of STI care received. CONCLUSIONS: References to COVID-19 and associated mitigation efforts were woven into Reddit posts pertaining to several domains of STI care. These data support the notion that Reddit discussions may represent a valuable source of STI information, standing to corroborate and further contextualize STI survey and surveillance work.

ABSTRACT

Improvements in context-specific programming are essential to address HIV and other sexually transmitted and blood-borne infection epidemics globally. A programme science approach emphasises the need for context-specific evidence and knowledge, generated on an ongoing basis, to inform timely and appropriate programmatic decisions. We aim to accelerate and improve the use of embedded research, inquiry, and learning to optimise population-level impact of public health programmes and to introduce an effective programme coverage framework as one tool to facilitate this goal. The framework was developed in partnership with public health experts in HIV and sexually transmitted and blood-borne infections through several workshops and meetings. The framework is a practice-based tool that centres on the use of data from iterative cycles of programme-embedded research and learning, as well as routine programme monitoring, to refine the strategy and implementation of a programme. This programme science approach aims to reduce programme coverage gaps, to optimise impact at the population level, and to achieve effective coverage. This framework should facilitate the generation of programme-embedded research and learning agendas to inform resource allocation, optimise population-level impact, and achieve equitable and effective programme coverage.

ABSTRACT

BACKGROUND: Telehealth offers one approach to improving access to sexually transmitted infection (STI) prevention and care services. Therefore, we described recent telehealth use among those providing STI-related care and identified opportunities for improving STI service delivery. MATERIALS AND METHODS: Using the DocStyles Web-based, panel survey conducted by Porter Novelli from September 14 to November 10, 2021, 1500 healthcare providers were asked about their current telehealth usage, demographics, and practice characteristics, and compared STI providers (≥10% of time spent on STI care and prevention) to non-STI providers. RESULTS: Among those whose practice consisted of at least 10% STI visits (n = 597), 81.7% used telehealth compared with 75.7% for those whose practice consisted of less than 10% STI visits (n = 903). Among the providers with at least 10% STI visits in their practice, telehealth use was highest among obstetrics and gynecology specialists, those practicing in suburban areas, and those practicing in the South. Among providers whose practice consisted of at least 10% STI visits and who used telehealth (n = 488), the majority were female and obstetrics and gynecology specialists practicing in suburban areas of the South. After controlling for age, gender, provider specialty, and geographic location of their practice, providers whose practice consisted of at least 10% STI visits had increased odds (odds ratio, 1.51; 95% confidence interval, 1.16-1.97) of using telehealth compared with providers whose visits consisted of less than 10% STI visits. CONCLUSIONS: Given the widespread use of telehealth, efforts to optimize delivery of STI care and prevention via telehealth are important to improve access to services and address STIs in the United States.

ABSTRACT

OBJECTIVE: Condom use behaviours are proximal to recent STI increases in the USA, yet it remains unclear whether the use of condoms has changed over time among unmarried, non-cohabiting young men who have sex with women (MSW) and how this variability is influenced by STI risk factors. METHODS: To examine condom use over time among MSW aged 15-29, we used three cross-sectional surveys from the 2002, 2006-2010 and 2011-2017 National Survey of Family Growth. We estimated weighted percentages, adjusted prevalence ratios (APRs) and 95% confidence intervals (CI) to assess changes in condom use, stratified by whether MSW reported any STI risk factors in the past 12 months (ie, perceived partner non-monogamy, male-to-male sex, sex in exchange for money or drugs, sex partner who injects illicit drugs, or an HIV-positive sex partner). RESULTS: We observed a divergence in trends in condom use at last sex between men aged 15 -29 with STI risk factors in the past 12 months and those without such history. We saw significant declines in condom use from 2002 to 2011-2017 among men with STI risk factors (APR=0.80, 95% CI 0.68 to 0.95), specifically among those aged 15-19 (APR=0.73, 95% CI 0.57 to 0.94) or non-Hispanic white (APR=0.71, 95% CI 0.54 to 0.93). In contrast, trends in condom use among men with no STI factors remained stable or increased. Across all time periods, the most prevalent STI risk factor reported was perception of a non-monogamous female partner (23.0%-26.9%). Post-hoc analyses examined whether condom use trends changed once this variable was removed from analyses, but no different patterns were observed. CONCLUSIONS: While STIs have been increasing, men aged 15-29 with STI risk factors reported a decline in condom use. Rising STI rates may be sensitive to behavioural shifts in condom use among young MSW with STI risk factors.

ABSTRACT

Social media forums provide a window into how gay, bisexual, and other men who have sex with men talk about pre-exposure prophylaxis for HIV prevention (PrEP) outside of research contexts. To examine information exchange about this important pillar of HIV prevention, discussions around PrEP were collected from the r/askgaybros subreddit of the social media site Reddit (2014-2019). Post titles and asks were qualitatively coded to identify themes describing the primary purpose of the post. In all, 1163 PrEP posts were identified, and a 23.3-fold increase in post volume was seen from 2014 (n = 20) to 2019 (n = 466). The most common post type was a mention of PrEP in a post primarily discussing: an assessment of risk after a sexual encounter (19.2%); a sexual or romantic relationship (6.0%); or other (29.3%). Access challenges (19.1%), information seeking (17.5%), and the cultural effects of PrEP on the gay community (16.3%) were other common themes. Posts regarding the initiation of PrEP (11.8%) and PrEP side-effects (9.4%) were moderately represented. Posts addressing promotion, shade, stigma, and usage were infrequent (≤ 5.5% of posts, respectively). Over time, discussion of PrEP has increased exponentially on r/askgaybros, which may reflect the normalization of PrEP. Qualitative analysis of these posts can be a rich source of data for scientists, practitioners, and healthcare providers interested in increasing uptake of PrEP and decreasing barriers to its use.

ABSTRACT

We examine the typologies of workplaces for sex workers in Dnipro, Ukraine as part of the larger Dynamics Study, which explores the influence of conflict on sex work. We conducted a cross-sectional survey with 560 women from September 2017 to October 2018. The results of our study demonstrate a diverse sex work environment with heterogeneity across workplace typologies in terms of remuneration, workload, and safety. Women working in higher prestige typologies earned a higher hourly wage, however client volume also varied which resulted in comparable monthly earnings from sex work across almost all workplace types. While sex workers in Dnipro earn a higher monthly wage than the city mean, they also report experiencing high rates of violence and a lack of personal safety at work. Sex workers in all workplaces, with the exception of those working in art clubs, experienced physical and sexual violence perpetrated by law enforcement officers and sex partners. By understanding more about sex work workplaces, programmes may be better tailored to meet the needs of sex workers and respond to changing work environments due to ongoing conflict and COVID-19 pandemic.

ABSTRACT

Pelvic inflammatory disease (PID) is a syndrome that causes substantial morbidity, including chronic pelvic pain, to women globally. While limited data are available from low- and middle-income countries, national databases from the United States and Europe suggest that PID incidence may be decreasing but the rate of decrease may differ by the etiologic cause. Recent studies of women with PID have reported that fewer than half of women receiving a diagnosis of PID have gonococcal or chlamydial infection, while Mycoplasma genitalium, respiratory pathogens, and the constellation of bacteria associated with bacterial vaginosis may account for a substantial fraction of PID cases. The clinical diagnosis of PID is nonspecific, creating an urgent need to develop noninvasive tests to diagnose PID. Advances in serologic testing for Chlamydia trachomatis and Neisseria gonorrhoeae could advance epidemiologic studies, while the development of vaccines against these sexually transmitted pathogens could affect incident PID and associated morbidity.

ABSTRACT

BACKGROUND: Previous studies have shown substantial differences in geographic clustering of sexually transmitted infections (STI), such as chlamydia (CT) and gonorrhea (NG), conditional on epidemic phase. Chlamydia and NG have recently shown resurgent epidemiology in the northern hemisphere. This study describes the recent epidemiology of CT and NG in Winnipeg, Canada, combining traditional surveillance tools with place-based analyses, and comparing the ecological niches of CT and NG, in the context of their evolving epidemiology. METHODS: Data were collected as part of routine public health surveillance between 2007 and 2016. Secular trends for CT and NG, and CT/NG coinfection were examined. Gini coefficients and population attributable fractions explored the distribution, and concentration of infections over time and space. RESULTS: Rates of CT increased from 394.9/100,000 population to 476.2/100,000 population from 2007 to 2016. Gonorrhea rates increased from 78.0/100,000 population to 143.5/100,000 population during the same period. Each pathogen had its own ecological niche: CT was widespread geographically and socio-demographically, while NG was clustered in Winnipeg's inner-core. CT/NG co-infections had the narrowest space and age distribution. NG was shown to be undergoing a growth phase, with clear signs of geographic dispersion. The expansion of NG resembled the geographic distribution of CT. CONCLUSIONS: We demonstrated that NG was experiencing a growth phase, confirming theoretical predictions of geographic dispersion during a growth phase. During this phase, NG occupied similar geographic spaces as CT. Knowledge of different ecological niches could lead to better targeting of resources for subpopulations vulnerable to STIs.

ABSTRACT

OBJECTIVES: Despite a growing HIV threat, there is no definition and characterisation of key populations (KPs), who could be the major drivers of the epidemic in Turkey. We used programmatic mapping to identify locations where KPs congregate, estimate their numbers and understand their operational dynamics to develop appropriate HIV programme implementation strategies. METHODS: Female and transgender sex workers (FSWs and TGSWs), and men who have sex with men (MSM) were studied in Istanbul and Ankara. Within each district, hot spots were identified by interviewing key informants and a crude spot list in each district was developed. The spot validation process was led by KP members who facilitated spot access and interviews of KPs associated with that spot. Final estimates were derived by aggregating the estimated number of KPs at all spots, which was adjusted for the proportion of KPs who visit multiple spots, and for the proportion of KPs who do not visit spots. RESULTS: FSWs were the largest KP identified in Istanbul with an estimate of 30 447 (5.8/1000 women), followed by 15 780 TGSWs (2.9/1000 men) and 11 656 MSM (2.1/1000). The corresponding numbers in Ankara were 9945 FSWs (5.2/1000 women), 1770 TGSWs (1/1000 men) and 5018 MSM (2.5/1000 men). Each KP had unique typologies based on the way they find and interact with sex partners. MSM were mostly hidden and a higher proportion operated through internet and phone-based applications. Night time was the peak time with Friday, Saturday and Sunday being the peak days of activity in both Istanbul and Ankara. CONCLUSIONS: This study has highlighted the presence of a substantial number of FSWs, TGSW and MSM in Istanbul and Ankara. The information obtained from this study can be used to set priorities for resource allocation and provide HIV prevention services where coverage could be the highest.

ABSTRACT

Mother-to-child transmission of HIV (MTCT) accounts for a significant proportion of new HIV infections in Peru. The purpose of this case-control study was to examine maternal and infant factors associated with MTCT in Peru from 2015 to 2016. For each biologically confirmed case infant, we randomly selected four birth year- and birth hospital-matched controls from five hospitals in Lima-Callao. Maternal and infant information were gathered from medical records. Simple conditional logistic regression was utilized to examine possible maternal and infant characteristics associated with MTCT. The rate of MTCT was 6.9% in 2015 and 2.7% in 2016. A total of 63 matched controls were identified for 18 cases. Protective factors included higher number of prenatal visits (odds ratio [OR]: 0.72; 95% confidence interval [CI]: 0.55-0.94, p = 0.012) and having more children (OR: 0.10, 95% CI: 0.01-0.79, p = 0.029). Risk factors included later maternal diagnosis (OR: 1.19; 95% CI: 1.06-1.34; p = 0.001) and greater viral load at the time of maternal diagnosis (OR: 1.05; 95% CI: 1.01-1.10; p = 0.022). Our study highlights the importance of targeting early and continued prenatal care as specific areas to target to prevent gaps in the HIV treatment cascade for pregnant HIV-infected women. These strategies can ensure early screening and initiation of antiretroviral therapy to reduce MTCT rates.

ABSTRACT

PROBLEM: Receptive anal intercourse (RAI) is more efficient than receptive vaginal intercourse (RVI) at transmitting HIV, but its contribution to heterosexually acquired HIV infections among at-risk women in the USA is unclear. METHOD OF STUDY: We analysed sexual behaviour data from surveys of 9152 low-income heterosexual women living in 20 cities with high rates of HIV conducted in 2010 and 2013 as part of US National HIV Behavioral Surveillance. We estimated RAI prevalence (past-year RAI) and RAI fraction (fraction of all sex acts (RVI and RAI) at the last sexual episode that were RAI among those reporting past-year RAI) overall and by key demographic characteristics. These results and HIV incidence were used to calibrate a risk equation model to estimate the population attributable fraction of new HIV infections due to RAI (PAFRAI ) accounting for uncertainty in parameter assumptions. RESULTS: Receptive anal intercourse prevalence (overall: 32%, city range: 19%-60%) and RAI fraction (overall: 27%, city range: 18%-34%) were high overall and across cities, and positively associated with exchange sex. RAI accounted for an estimated 41% (uncertainty range: 18%-55%) of new infections overall (city range: 21%-57%). Variability in PAFRAI estimates was most influenced by uncertainty in the estimate of the per-act increased risk of RAI relative to RVI and the number of sex acts. CONCLUSION: Receptive anal intercourse may contribute disproportionately to new heterosexually acquired HIV infections among at-risk low-income women in the USA, meaning that tools to prevent HIV transmission during RAI are warranted. The number of RVI and RAI acts should also be collected to monitor heterosexually acquired HIV infections.

ABSTRACT

In the past two decades, major advances in biomedical intervention approaches to prevent HIV and many sexually transmissible infections (STIs) have shown great promise. However, challenges to prevention remain in the area of achieving population-level impact for biomedical prevention approaches. In this paper we address what social and behavioural research approaches can contribute beyond well-known behaviour change and counselling interventions. We organise work into five areas. Adherence and disinhibition research is primarily into individual-level constructs pertaining to maximising intervention effectiveness. Coverage research represents a population-level construct germane to maximising efficient prioritisation for prevention. Research covering social determinants, a second population-level construct, contributes to both prioritisation and effectiveness. Finally, disparities and social inequities need to be incorporated into prevention, given the pervasive and persistent disparities found in rates of HIV and STIs and in their antecedents.

ABSTRACT

Given the range of pre-exposure prophylaxis (PrEP) products currently being tested to prevent HIV in women, a standardized Acceptability and Use of PrEP Products Among Women Tool may facilitate comparisons of product acceptability and use across different geographies, trials, and users. We conducted three rounds of cognitive interviewing over 2 months in 2016, with 28 South African women who had experience participating in a range of PrEP product trials. The final instrument contained 41 items, including five new items that improved construct validity and 22 items modified for clarity. Changes were made due to unclear wording, difficulty answering, participant embarrassment, low response variability, and administrative formatting. Cognitive interviewing provided a means to address issues that would have inhibited this tool's ability to accurately collect data otherwise. This rapid, low-cost study provided valuable insight into participants' understanding of questions and demonstrated the utility of cognitive interviewing in international clinical trials.
