RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

From a nationally representative survey, 2011 to 2017, we found that 80.7% of sexually active men who have sex with men were insured and 82.0% had a usual place for care, but only 39.8% received sexual risk assessment and 45.8% received sexually transmitted disease screening, of whom 58.0% received extragenital sexually transmitted disease screening.

RESUMO

OBJECTIVES: Within the context of rising rates of reportable STIs in the USA, we used national survey data to examine temporal trends in high-risk factors that indicate need for STI/HIV preventive services among key subpopulations with disproportionate STI rates. METHODS: We used data from the 2002 (n=12 571), 2006-2010 (n=22 682) and 2011-2015 (n=20 621) National Survey of Family Growth (NSFG). NSFG is a national probability survey of 15-44 year olds living in US households. We examined STI risk factors among sexually active men who have sex with men (MSM) and Hispanic, non-Hispanic black, 15-19 year old, 20-24 year old, and 25-29 year old women who have sex with men (WSM) and men who have sex with women (MSW). Risk behaviours included: received money or drugs for sex, gave money or drugs for sex, partner who injected drugs, partner who has HIV, non-monogamous partner (WSM, MSW only) and male partner who had sex with other men (WSM only). Endorsement of any of these behaviours was recoded into a composite variable focusing on factors indicating increased STI risk (yes/no). We used chi-squares and logistic regression (calculating predicted marginals to estimate adjusted prevalence ratios (aPRs)) to examine STI risk factors over time among the key subpopulations. RESULTS: From 2002 to 2011-2015, reported STI risk factors did not change or declined over time among key subpopulations in the USA. In adjusted analyses comparing 2002 to 2011-2015, we identified significant declines among WSM: Hispanics (aPR=0.84 (0.68-1.04), non-Hispanic blacks (aPR=0.69 (0.58-0.82), adolescents (aPR=0.71 (0.55-0.91) and 25-29 year olds (aPR=0.76 (0.58-0.98); among MSW: Hispanics (aPR=0.53 (0.40-0.70), non-Hispanic blacks (aPR=0.74 (0.59-0.94) and adolescents (aPR=0.63 (0.49-0.82); and among MSM (aPR=0.53 (0.34-0.84). CONCLUSIONS: While reported STIs have increased, STI risk factors among key subpopulations were stable or declined. Condom use related to these risk factors, sexual mixing patterns and STI testing should be examined.

RESUMO

BACKGROUND: The association between county-level social capital indices (SCIs) and the 3 most commonly reported sexually transmitted infections (STIs) in the United States is lacking. In this study, we determined and examined the association between 2 recently developed county-level SCIs (ie, Penn State Social Capital Index [PSSCI] vs United States Congress Social Capital Index [USCSCI]) and the 3 most commonly reported bacterial STIs (chlamydia, gonorrhea, and syphilis) using spatial and nonspatial regression techniques. METHODS: We assembled and analyzed multiyear (2012-2016) cross-sectional data on STIs and 2 SCIs (PSSCI vs USCSCI) on counties in all 48 contiguous states. We explored 2 nonspatial regression models (univariate and multiple generalized linear models) and 3 spatial regression models (spatial lag model, spatial error model, and the spatial autoregressive moving average model) for comparison. RESULTS: Without exception, all the SCIs were negatively associated with all 3 STI morbidities. A 1-unit increase in the SCIs was associated with at least 9% (P < 0.001) decrease in each STI. Our test of the magnitude of the estimated associations indicated that the USCSCI was at least 2 times higher than the estimates for the PSSCI for all STIs (highest P value = 0.01). CONCLUSIONS: Overall, our results highlight the potential benefits of applying/incorporating social capital concepts to STI control and prevention efforts. In addition, our results suggest that for the purpose of planning, designing, and implementing effective STI control and prevention interventions/programs, understanding the communities' associational life (as indicated by the factors/data used to develop the USCSCI) may be important.

RESUMO

BACKGROUND: This study examined condom use and sexually transmitted infection (STI) testing among unmarried, non-cohabiting women and men who had multiple past-year partnerships or perceived their partner's involvement in another sexual relationship. METHODS: We identified 5868 and 5330 unmarried, non-cohabiting sexually active women and men aged 15 to 44 years using National Survey of Family Growth data for 2011 to 2017. To measure multiple partnerships, we created 4 dichotomous variables that included both past-year number of opposite-sex sex partners (1, 2 or more) and perceived partner nonmonogamy (PPNM) (yes, no). Results were stratified by relationship type at last sex ("steady" vs "casual"). RESULTS: Overall, 39.4% of women and 48.3% of men reported multiple partnerships and 23.4% and 24.0% reported PPNM. Lower condom use was seen for women and men who had 2 or more partners in the past year and PPNM than those with only 1 partner and no PPNM (women, 28.5%; 95% confidence interval [CI], 24.1-32.9 vs 39.3%; 95% CI, 36.6-41.9) (men, 37.7%; 33.5-41.8 vs 54.9%; 51.9-57.9). STI testing was higher for groups with PPNM. Men with a steady sex partner had higher prevalence of past-year STI testing if they reported PPNM than not (adjusted prevalence ratio, 2.00; 95% CI, 1.63-2.45). CONCLUSIONS: Screening practices that include a standardized sexual risk assessment could identify those with multiple sex partners or PPNM and improve linkage to STI services. Availability of point-of-care tests and expedited partner therapy could provide targeted strategies that prioritize rapid diagnosis and effective partner treatment which may prevent further STI spread.

RESUMO

We used the US national survey data to examine sexual behavior by pregnancy status and found that, overall, pregnant women did not differ from nonpregnant women in penile-anal sex and associated condom use. Compared with nonpregnant women, pregnant women had lower or similar reports of other sexual behaviors.
