The Impact

HIV and other sexually transmitted infections remain a burden on men who have sex with men in the era of effective combination antiretroviral therapy. New prevention efforts are therefore needed. One of these approaches is the current country-wide free condom distribution at gay bars with darkrooms and gay saunas in the Netherlands. This study assessed the effects of free condom distribution on incidence and burden of disease of HIV and other sexually transmitted infections.A model was constructed to calculate the impact of free condom distribution on HIV, hepatitis C, chlamydia, gonorrhoea, and syphilis among men who have sex with men visiting these venues. Outcomes included new infections averted and disability-adjusted life years averted. Scenario studies were performed to predict the effects of a further increase of condom use, condom effectiveness and coverage. Lastly, cost-effectiveness and sensitivity analyses were performed.Condom use at public sex venues increased after the intervention. Our model showed decreases in annual incidence risk, ranging from 5.73% for gonorrhoea to 7.62% for HIV. The annual number of new infections averted was largest for chlamydia and gonorrhoea (261 and 394 infections, respectively), but 42 new HIV infections were averted as well. Over 98% of the decrease in burden of disease was due to HIV. In scenarios where condom use and condom effectiveness were further increased, this reduction became more extensive. The intervention was cost-effective and cost-saving (for every €1 spent on condom distribution, €5.51 was saved) and remained this in all sensitivity analyses.Free condoms at public sex venues can reduce the transmission of HIV and other sexually transmitted infections. Condom distribution is an affordable and easily implemented intervention that can reduce the burden of disease in men who have sex with men substantially.

The Impact

Sexually transmitted infections (STIs) are often associated with chronic diseases and can have severe impacts on host reproductive success. For airborne or socially transmitted pathogens, patterns of contact by which the infection spreads tend to be dispersed and each contact may be of very short duration. By contrast, the transmission pathways for STIs are usually characterized by repeated contacts with a small subset of the population. Here we review how heterogeneity in sexual contact patterns can influence epidemiological dynamics, and present a simple model of polygyny/polyandry to illustrate the impact of biased mating systems on disease incidence and pathogen virulence.

AbstractLatinos in the United States are disproportionately affected by Human Immunodeficiency Virus and sexually transmitted infections (STIs). They account for about 24 % of newly diagnosed AIDS cases each year and are two to three times more likely to develop STIs when compared with non-Latino whites. Limited knowledge of STIs has remained one of the contributing factors to the disparity. The purpose of this study was to implement an educational bundle and evaluate its effectiveness in increasing STI knowledge and consistent condom use among adult Latinos seen in an outpatient clinic that serves low income patients. A pre- and post-test design was used to evaluate changes in STI knowledge and consistency of condom use. The educational bundle consisted of YouTube STI-related videos, a pre-designed one to one educational session, provision of condoms and STI-related educational materials. Self-administered questionnaires were used to collect data at baseline and one week post implementation of the educational bundle. Forty-six Latinos (18 females and 28 males) ranging in ages 19 to 60 years participated in the project. The total mean STI knowledge and condom use frequency improved from pre-test (M = 1.67, M = 3.09) to post-test (M = 3.80, M = 5.33). Results of paired samples t-tests demonstrated statistically significant differences between total mean STI knowledge (t(45) = –15.48, p < 0.001) and condom use frequency (t(45) = –7.09, p < 0.001) at pre-test and post-testing. The educational bundle was effective in increasing STI knowledge and consistent condom use among adult Latinos in an outpatient clinic. Further study needs to be done to determine the long-term effect of this mode of education for this population.

Biological And Behavioral Surveillance

Condom use during last sexual contact is a survey measure that may be used to inform monitoring and evaluation indicators of recent condom use in populations at risk for HIV infection and other sexually transmitted infections, such as the uniformed services. The authors tested for differences in condom use measures that were fielded within separate Biological and Behavioral Surveillance Surveys conducted in the armed forces of two separate nations: the Dominican Republic and Belize. Both surveys included measures of condom use during last sexual contact with specified partners and both surveys included the Risk Behavior Assessment (RBA), which measures specific sexual acts and condom use frequency during a specified time period. In both samples, more than 40% of respondents who reported condom use during last sexual contact with a regular partner also reported engaging in unprotected sex when screened with the RBA. Furthermore, more than 60% of respondents who reported condom use during last sexual encounter with a commercial sex worker also reported engaging in unprotected sex when screened with the RBA. The results carry implications for monitoring and evaluation indicators of large-scale HIV prevention programs. The authors recommend that, when feasible, more in-depth instruments such as the RBA be considered to measure recent condom use in populations of uniformed services personnel.

The construction of Caribbean male identities based on ideas of masculinity has raised widespread concerns across the island states, and in a region with such high rates of teenage pregnancy (18%), stigmatizing safe sex, contraception, and HIV/AIDS prevalence can only exacerbate the problem. The purpose of this study was to examine the extent to which males use condoms and to explore the association of condom use with their concern with acquiring and transmission of sexually transmitted infections.
