Disparities In Sexually Transmitted Infections Research Articles

Laboratory Perspective on Racial Disparities in Sexually Transmitted Infections.

BackgroundRates of sexually transmitted infections (STI) have risen steadily in recent years, and racial and ethnic minorities have borne the disproportionate burden of STI increases in the United States. Historical inequities and social determinants of health are significant contributors to observed disparities and affect access to diagnostic testing for STI.ContentPublic health systems rely heavily on laboratory medicine professionals for diagnosis and reporting of STI. Therefore, it is imperative that clinicians and laboratory professionals be familiar with issues underlying disparities in STI incidence and barriers to reliable diagnostic testing. In this mini-review, we will summarize contributors to racial/ethnic disparity in STI, highlight current epidemiologic trends for gonorrhea, chlamydia, and syphilis, discuss policy issues that affect laboratory and public health funding, and identify specific analytic challenges for diagnostic laboratories.SummaryRacial and ethnic disparities in STI in the US are striking and are due to complex interactions of myriad social determinants of health. Budgetary cuts for laboratory and public health services and competition for resources during the COVID-19 pandemic are major challenges. Laboratory professionals must be aware of these underlying issues and work to maximize efforts to ensure equitable access to diagnostic STI testing for all persons, particularly those most disproportionately burdened by STI.

Geographic Variation in Condom Availability and Accessibility

Identifying predictors that contribute to geographic disparities in sexually transmitted infections (STIs) is necessary in order to reduce disparities. This study assesses the spatial relationship condom availability and accessibility in order to better identify determinants of geographic disparities in STIs. We conducted a telephone-based audit among potential-condom selling establishments. Descriptive analyses were conducted to detect differences in condom-selling characteristics by stores and by store type. Geocoding, mapping, and spatial analysis were conducted to measure the availability of condoms. A total of 850 potential condom-selling establishments participated in the condom availability and accessibility audit in St. Louis city; 29% sold condoms. There were several significant geographic clusters of stores identified across the study area. The first consisted of fewer convenience stores and gas stations that sold condoms in the northern section of the city, whereas condoms were less likely to be sold in non-convenience store settings in the southwestern and central parts of the city. Additionally, locations that distributed free condoms clustered significantly in city center. However, there was a dearth of businesses that were neither convenience stores nor gas stations in the northern region of the city, which also had the highest concentration of condoms sold. This initial study was conducted to provide evidence that condom availability and accessibility differ by geographic region, and likely are a determinant of social norms surrounding condom use and ultimately impact STI rates.

Associations of sexually transmitted infections with condom problems among young men who have sex with men.

Young men who have sex with men (YMSM) are disproportionately infected with sexually transmitted infections (STIs). Condom use is the most widely available means of preventing the transmission of STIs, but effectiveness depends on correct use. Condom errors such as using an oil-based lubricant have been associated with condom failures such as breakage. Little research has been done on the impact of condom problems on the likelihood of contracting an STI. Data came from Crew 450, a longitudinal study of HIV risk among YMSM (N = 450). All self-report data were collected using computer-assisted self-interview technology, and clinical testing was done for gonorrhea, chlamydia, and HIV. Nearly all participants made at least 1 error, with high rates of using oil-based lubricant and incomplete use. No differences were found in rates of condom problems during anal sex with a man versus vaginal sex with a woman. Black YMSM reported significantly higher use of oil-based lubricants than white and Hispanic YMSM, an error significantly associated with HIV status (adjusted odds ratio, 2.60; 95% confidence interval, 1.04-6.51). Participants who reported a condom failure were significantly more likely to have an STI (adjusted odds ratio, 3.27; 95% confidence interval, 1.31-8.12). Young men who have sex with men report high rates of condom problems, and condom failures were significantly associated with STIs after controlling for unprotected sex. Educational programs are needed to enhance correct condom use among YMSM. Further research is needed on the role of oil-based lubricants in explaining racial disparities in STIs and HIV.
