Sexual Risk Behaviours (sexual + risk_behaviour)
Selected AbstractsHighly active antiretroviral therapy (HAART) among HIV-infected drug users: a prospective cohort study of sexual risk and injecting behaviourADDICTION, Issue 3 2006Colette Smit ABSTRACT Aims To study sexual risk and injecting behaviour among HIV-infected drug users (DU) receiving highly active antiretroviral therapy (HAART)., Design and setting As part of an ongoing prospective cohort study, HIV-infected DU who commenced HAART (n = 67) were matched with those not starting HAART (n = 130) on CD4 cell counts, duration of cohort participation, age and calendar year of visit. Immunological and virological responses of the HAART-treated DU were compared with the HAART-treated homosexual men from the same cohort (n = 212). Measurements Trends in behaviour and therapeutic response were tested with a logistic regression model adjusted for repeated measurements and a piecewise random effects model, respectively. Findings Non-HAART users reported more episodes of injecting than HAART users. In both groups injecting declined over time with no effect of HAART initiation. Before HAART initiation an increase in sexual risk behaviour was observed among those who had been assigned to receive HAART; their sexual risk behaviour declined thereafter. No change in sexual risk behaviour was found among non-HAART users. Relative to homosexual men, DU had a similar initial therapeutic response, but DU started HAART at lower CD4 cell counts and higher viral load levels. Conclusion DU who are treated with HAART are not increasing their risk behaviour, and their early response to HAART is similar to homosexual men. However, before the treated DU received HAART they were seen to inject less often than those not treated with HAART. This suggests that selection of potential HAART starters is based on limited drug use. Although the DU who commence HAART are a selected group, our results show that HIV-infected DU can be treated effectively. [source] Risk and protective behaviours of bisexual minority women: a qualitative analysisINTERNATIONAL NURSING REVIEW, Issue 2 2005J. D. Champion phd Background, Public health messages urging women to seek health care services such as sexually transmitted diseases (STD) and cervical cancer screening or family planning services fail to address women who have sex with women (WSW). This negligence may have led to a false sense of security amongst WSW concerning sexual risk behaviour. Research has shown that WSW engaged in more high-risk sexual behaviours than heterosexual women. WSW has been identified as an important vector in the spread of STDs in all populations because of bisexuality. To prevent and reduce transmission of STDs amongst WSW, perceptions of risk for STD amongst WSW need to be understood so that effective interventions may be developed. Aim, To describe the relationship between sexual risk and protective behaviour and STD transmission amongst bisexual minority women with a history of STD. Methods, Life history methods were used to interview 23 African-American bisexual women with a history of STD. Findings, Various themes unfolded during analysis of the patient interviews, including bisexual women's perceptions of STD risk, the context of sexual relationships with women and STD prevention, screening, and treatment practices. Conclusions, The contexts of sexual relationships including multiple or concurrent partner relationships with both men and women placed these women at high risk for STD. Regardless of the type of relationship or belief it is possible to get an STD, protection was often not used. These circumstances identify an extremely high-risk population of women with need for more extensive research to identify strategies for health care interventions. [source] Prevalence of HIV, hepatitis C and syphilis among injecting drug users in Russia: a multi-city studyADDICTION, Issue 2 2006Tim Rhodes ABSTRACT Objectives To estimate the prevalence of HIV, hepatitis C virus (HCV) and syphilis in injecting drug users (IDUs) in Russia. Methods Unlinked anonymous cross-sectional survey of 1473 IDUs recruited from non-treatment settings in Moscow, Volgograd and Barnaul (Siberia), with oral fluid sample collection for HIV, HCV antibody (anti-HIV, anti-HCV) and syphilis testing. Results Prevalence of antibody to HIV was 14% in Moscow, 3% in Volgograd and 9% in Barnaul. HCV prevalence was 67% in Moscow, 70% in Volgograd and 54% in Barnaul. Prevalence of positive syphilis serology was 8% in Moscow, 20% in Volgograd and 6% in Barnaul. Half of those HIV positive and a third of those HCV positive were unaware of their positive status. Common risk factors associated with HIV and HCV infection across the cities included both direct and indirect sharing of injecting equipment and injection of home-produced drugs. Among environmental risk factors, we found increased odds of anti-HIV associated with being in prison in Moscow, and some association between official registration as a drug user and anti-HIV and anti-HCV. No associations were found between sexual risk behaviours and anti-HIV in any city. Conclusions HIV prevalence among IDUs was markedly higher than city routine surveillance data suggests and at potentially critical levels in terms of HIV prevention in two cities. HCV prevalence was high in all cities. Syphilis prevalence highlights the potential for sexual risk and sexual HIV transmission. Despite large-scale testing programmes, knowledge of positive status was poor. The scaling-up of harm reduction for IDUs in Russia, including sexual risk reduction, is an urgent priority. [source] Association between periodontal disease, bacterial vaginosis, and sexual risk behavioursJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 10 2010Emily Craig Zabor Zabor EC, Klebanoff M, Yu K, Zhang J, Nansel T, Andrews W, Schwebke J, Jeffcoat M. Association between periodontal disease, bacterial vaginosis, and sexual risk behaviours. J Clin Periodontol 2010; 37: 888,893. doi: 10.1111/j.1600-051X.2010.01593.x. Abstract Background: Both periodontal disease and bacterial vaginosis may cause adverse pregnancy outcomes. This study evaluated the association between periodontal disease and bacterial vaginosis. Materials and Methods: Data from 3569 women enrolled in the Longitudinal Study of Vaginal Flora were used. Periodontal disease, defined as greater than three sites with ,4 mm attachment loss, was assessed by specially calibrated hygienists at baseline. Positive bacterial vaginosis status was based on a Nugent Gram stain score ,7. Pairs of independent variables were compared with Pearson's ,2 and risk ratios were calculated through log-binomial regression. Results: Twenty-eight per cent of women with bacterial vaginosis had periodontal disease compared with 22% without , corresponding to 1.29 (95% CI: 1.13, 1.47) times greater risk of periodontal disease among women with bacterial vaginosis. In adjusted analysis the risk ratio dropped to 1.23 (95% CI: 1.08, 1.40). Receptive oral sex with an uncircumcised partner was associated with 1.28 times (95% CI: 0.97, 1.69) the risk for periodontal disease compared with receptive oral sex with a circumcised partner, though the association is not statistically significant. Conclusions: In this population, there is a small but significant association between periodontal disease and bacterial vaginosis and a possible trend between receptive oral sex with an uncircumcised partner and periodontal disease. [source] Associations between youth assets and sexual activity: does adult supervision play a role?CHILD: CARE, HEALTH AND DEVELOPMENT, Issue 4 2007L. Harris Abstract Background, Youth participation in sexual risk behaviours continues to be a critically important public health topic. Additionally, as youth are frequently being left alone during the day without adult supervision, there are increased opportunities for sexual risk-taking behaviour. This study examined how the relationships of nine youth assets and sexual activity may vary according to the stratification of youth into two groups: self-care and supervised. Methods, Data were collected through at-home, in-person interviews from a random sample of inner-city youth (mean age = 15.4 years; 51.5% female; 48.8% White; 22.4% Black; 18.5% Hispanic; 10% Native American) and their parents (n = 1079 parent/youth pairs). Nine youth assets were analysed using multiple logistic regression. Examples of assets youth may possess are: positive role models, family communication, school connectedness, constructive use of time and aspirations for the future. The item used to assess sexual intercourse was ,Have you ever had sexual intercourse ("done it", "had sex", "made love", "gone all the way")?'. Asset/risk behaviour associations that were unique to one of the two strata were the focus of the study. Results, Thirty-seven per cent of youth spent two or more hours per day home alone. Youth who were supervised had a greater number of unique significant associations between assets and sexual activity than youth who were in the self-care group. Conclusions, Youth in supervised settings may be less likely to participate in sexual activity because of the presence of assets. Certain assets may also be important in deterring sexual activity for youth who are in self-care. [source] | ||||||||||
