Perceptions of health care professionals and patients about the risk of HIV transmission through oral sex: a qualitative study

Knowledge, attitudes and beliefs regarding HIV among medical students in Zagreb, Croatia

BACKGROUND

Medical students, as future health-care providers (HCPs) play a significant role in shaping attitudes towards people living with HIV/AIDS (PLWHA) and should possess adequate knowledge of this infection. The study aim was to assess knowledge about HIV among medical students of the University of Zagreb School of Medicine, and to determine the level of discriminatory attitudes towards PLWHA.

METHODS

We assessed knowledge about epidemiology, treatment, and prevention of HIV by using closed-ended and multiple-choice questions. Likert-scale questions were employed to determine attitudes towards PLWHA. Bivariate and multivariate ordinal logistic regression was used to assess correlates of certain discriminatory attitudes.

RESULTS

561 medical students participated, with 46.7% attending preclinical courses. Overall, 42.1% of students think they received sufficient information on HIV/AIDS during elementary and high school education. Among clinical students, 42.6%, 20.8% and 11.8% estimated accurately transmission risk after a needle injury, unprotected vaginal, and anal intercourse, respectively. 66.8% of clinical students were aware that treatment can prevent AIDS, while 58.7% and 69.8% were familiar with the rationale of using pre-exposure (PrEP) and post-exposure prophylaxis (PEP). In the multivariate analysis, individuals lacking infectology course attendance (aOR = 1.45; CI: 1.00-2.09) and those unaware of transmission routes (aOR = 1.49; CI: 1.06-2.09) showed higher odds of advocating HIV status disclosure compared to those who did not yet attend an infectology course. Students supporting extra protection for handling PLWHA bodily fluids were more likely to support refusal to treat PLWHA (aOR = 1.80; CI: 1.22-2.69) compared to those who did not support that opinion. Males were more inclined to state that they would refuse to treat PLWHA (aOR = 1.66; CI: 1.11-2.50) and disclose their HIV status (aOR = 1.62; CI: 1.17-2.27) than females. Overestimating needle injury transmission risk raised treatment refusal likelihood (aOR = 2.22; CI = 1.29-3.92) compared to those accurately informed of this risk.

CONCLUSION

Results indicate lack of knowledge of HIV transmission risks after specific exposures and about PrEP, PEP and treatment effectiveness. Gender and knowledge about HIV transmission risks influence students' attitudes towards PLWHA. Medical education should be focused on fostering correct attitudes and addressing stigma, which undermines prevention and treatment outcomes of PLWHA.

Oral and anal sex are key to sustaining gonorrhoea at endemic levels in MSM populations: a mathematical model

OBJECTIVES

Despite early treatment of urethral infection, gonorrhoea is endemic in urban populations of men who have sex with men (MSM) in Australia. By contrast, gonorrhoea is not common in urban heterosexual populations. Sexual activities among MSM usually involve anal or oral sex, and as these behaviours are becoming increasingly common among heterosexuals, there is a need to investigate their roles in transmission of gonorrhoea.

METHODS

We developed individual-based models of transmission of gonorrhoea in MSM and heterosexuals that incorporate anatomical site-specific transmission of gonorrhoea. We estimated the probabilities of transmission for anal sex and oral sex by calibrating an MSM model against prevalence of gonorrhoea and sexual activity data. These probabilities were then applied to a heterosexual model in order to examine whether gonorrhoea can persist in a heterosexual population through the addition of anal sex and oral sex.

RESULTS

In the MSM model, gonorrhoea can persist despite prompt treatment of urethral infections. The probability of gonorrhoea persisting is reduced if use of condom for oral sex is increased to more than 15% of acts. Assuming that treatment of symptomatic infections is prompt, gonorrhoea is unlikely to persist in a heterosexual population even with the addition of anal and oral sex.

CONCLUSIONS

Our models suggest that oral sex has an important role in sustaining gonorrhoea in a population of MSM by providing a pool of untreated asymptomatic infection. The importance of anal sex or oral sex in sustaining gonorrhoea in a heterosexual population remains uncertain due to the lack of information linking different types of sex acts and transmissibility.

Oral versus anal sex at last encounter -- behavioral differences among men who have sex with men in the District of Columbia

Oral sex may be used as a form of harm reduction against HIV transmission. We compared characteristics of men who have sex with men (MSM) in Washington, DC having oral sex versus those having anal sex at last encounter. Data collected through National HIV Behavioral Surveillance in 2008 using venue-based sampling were used. Men ≥18 years old disclosing MSM behavior in the past year were analyzed (n=500); OraQuick and Western Blot confirmation were used to assess HIV status. Multivariable methods were used for data analyses by type of sex at last encounter. A total of 71.8% of MSM had anal sex and 28.2% reported oral sex at last encounter. Men reporting oral sex were more likely to be white, older, insured, HIV-negative, unaware of last partner's HIV status, have a main partner, and not be HIV tested in the previous year. Significant demographic and behavioral differences exist between MSM reporting oral or anal sex; further studies should assess whether oral sex is being used as HIV prevention among MSM.

Reframing "prevention with positives": incorporating counseling techniques that improve the health of HIV-positive patients

Federal HIV prevention strategy seeks to increase efforts by health care providers to identify and reduce their HIV-positive patients' transmission-related behaviors. Implementation of these recommendations will be hindered if providers perceive these efforts have the potential to harm their relationships with patients. Because transmission-related behaviors (unsafe sex and sharing needles) and the related issues of drug and alcohol use also jeopardize the health of HIV-positive patients, providers can use patient-centered counseling when addressing those behaviors. We suggest efforts to increase provider-delivered transmission-prevention counseling be reframed so that "prevention with positives" includes the goal of protecting HIV-positive patients' health. We review the specific consequences of these risky behaviors on HIV-positive patients' health and review brief counseling strategies appropriate for HIV care providers.

HIV/AIDS: sex, abstinence, and behaviour change

HIV prevention has focused on reducing the chances of transmission of the pathogen via sexual transmission. We argue that current pressures to persuade people that "abstinence" is a reasonable programme goal are based on misapprehension as to the balance between environmental and contextual factors and individual choices in determining why and how people have sex. Continuing insistence on the part of major prevention programme funders that changing behaviour alone--rather than changing its context--is the main problem will result in poor policy choices. It is particularly important to get these choices right at a time when increased amounts of money are becoming available for engagement with the HIV/AIDS epidemic. Failure to take account of this problem may have results beyond the field of HIV prevention.

Oral versus vaginal sex among adolescents: perceptions, attitudes, and behavior

OBJECTIVE

Despite studies indicating that a significant proportion of adolescents are having oral sex, the focus of most empirical studies and intervention efforts concerning adolescent sexuality have focused on vaginal intercourse. This narrow focus has created a void in our understanding of adolescents' perceptions of oral sex. This study is the first to investigate adolescents' perceptions of the health, social, and emotional consequences associated with having oral sex as compared with vaginal sex, as well as whether adolescents view oral sex as more acceptable and more prevalent than vaginal sex.

METHODS

Participants were 580 ethnically diverse ninth-grade adolescents (mean age: 14.54; 58% female) who participated in a longitudinal study on the relationship between risk and benefit perceptions and sexual activity. Participants completed a self-administered questionnaire that inquired about their sexual experiences and percent chance of experiencing outcomes from, attitudes toward, and perceived prevalence of oral versus vaginal sex among adolescents.

RESULTS

More study participants reported having had oral sex (19.6%) than vaginal sex (13.5%), and more participants intended to have oral sex in the next 6 months (31.5%) than vaginal sex (26.3%). Adolescents evaluated oral sex as significantly less risky than vaginal sex on health, social, and emotional consequences. Adolescents also believed that oral sex is more acceptable than vaginal sex for adolescents their own age in both dating and nondating situations, oral sex is less of a threat to their values and beliefs, and more of their peers will have oral sex than vaginal sex in the near future.

CONCLUSIONS

Given that adolescents perceive oral sex as less risky, more prevalent, and more acceptable than vaginal sex, it stands to reason that adolescents are more likely to engage in oral sex. It is important that health care providers and others who work with youths recognize adolescents' views about oral sex and broaden their clinical preventive services to include screening, counseling, and education about oral sex.
