Barriers to condom use

Trends in the sexual behaviour of 15-year olds in Scotland: 2002-14

Background

Early sexual initiation and inadequate contraceptive use can place adolescents at increased risk of unplanned pregnancy and sexually transmitted infections. These behaviours are patterned by gender and may be linked to social inequalities. This paper examines trends in sexual initiation and contraceptive use by gender and family affluence for Scottish adolescents.

Methods

Cross-sectional data from four nationally representative survey cycles (2002, 2004, 2010, 2014) (n = 8895) (mean age = 15.57) were analysed. Logistic regressions examined the impact of survey year on sexual initiation, condom use and birth control pill (BCP) use at last sex; as well as any changes over time in association between family affluence and the three sexual behaviours. Analyses were stratified by gender.

Results

Between 2002 and 2014, adolescent males and females became less likely to report having had sex. Low family affluence females were more likely to have had sex than high family affluence females, and this relationship did not change over time. Condom use at last sex was reported less by males since 2002, and by females since 2006. Low family affluence males and females were less likely to use condoms than high family affluence participants, and these relationships did not change over time. There were no effects of time or family affluence for BCP use.

Conclusion

There has been a reduction in the proportion of 15-year olds in Scotland who have ever had sex, but also a decrease in condom use for this group. Economic inequalities persist for sexual initiation and condom use.

Variability in Condom Use Trends by Sexual Risk Behaviors: Findings from the 2003-2015 National Youth Risk Behavior Surveys

OBJECTIVE

This study aimed to examine variability in condom use trends by sexual risk behavior among US high school students.

METHODS

Data were from the 2003-2015 national Youth Risk Behavior Surveys conducted biennially among a nationally representative sample of students in grades 9 to 12. We used logistic regression to examine variability in trends of condom use during last sexual intercourse among female and male students by 4 sexual risk behaviors: drank alcohol or used drugs before last sexual intercourse, first sexual intercourse before age 13 years, 4 or more sex partners during their life, and 2 or more sex partners during the past 3 months.

RESULTS

Between 2003 and 2015, significant declines in self-reported condom use were observed among black female (63.6% in 2003 to 46.7% in 2015) and white male students (69.0% in 2003 to 58.1% in 2015). Among female students, declines in self-reported condom use were significant only among those who drank or use drugs before last sexual intercourse, had 4 or more sex partners during their life, or had 2 or more sex partners during the past 3 months. There was a significant interaction between trends in condom use and first sexual intercourse before age 13 years, suggesting more pronounced declines among female students who initiated first sexual intercourse before age 13 years compared with their female peers. Trends did not vary by sexual risk behavior for male students.

CONCLUSIONS

Results suggest that declines in self-reported condom use have occurred among female students at greater risk for acquiring a sexually transmitted disease.

Comparing the awareness of and beliefs in sexually transmitted infections among university students in Madagascar and the United States of America

Young adults have a higher risk of contracting sexually transmitted infections (STIs) than other age groups. This risk may be mediated by their social and cultural setting which can impact young adults’ awareness of, beliefs in, and risk of contracting STIs (including HIV/AIDS). In order to understand how these factors vary among young adults of different cultures, it is important to study these issues on a cross-cultural scale. This study aimed to increase understanding of the relationship between the culture of a place of study and: (1) STI awareness; (2) belief in STIs; and (3) self-reported STI prevalence in the study population. Survey data were collected from university students in Madagascar (n = 242 surveys in 2013) and the United States of America (n = 199 surveys in 2015). Compared to students at the American university, students at the Malagasy university: (1) did not appear to have a conclusively lower awareness of STIs; (2) did not differ in rates of belief in the existence of gonorrhea and syphilis, but had higher rates of disbelief in HIV/AIDS; and (3) were more likely to report having been infected with syphilis and gonorrhea, but not with HIV/AIDS. Students at the Malagasy university also listed different reasons than the students at the American university for why they believed in the existence of STIs. These findings highlight the need for further cross-cultural research to better adapt intervention strategies to different cultural settings.

The Men's Safer Sex project: intervention development and feasibility randomised controlled trial of an interactive digital intervention to increase condom use in men

BACKGROUND

This report details the development of the Men's Safer Sex website and the results of a feasibility randomised controlled trial (RCT), health economic assessment and qualitative evaluation.

OBJECTIVES

(1) Develop the Men's Safer Sex website to address barriers to condom use; (2) determine the best design for an online RCT; (3) inform the methods for collecting and analysing health economic data; (4) assess the Sexual Quality of Life (SQoL) questionnaire and European Quality of Life-5 Dimensions, three-level version (EQ-5D-3L) to calculate quality-adjusted life-years (QALYs); and (5) explore clinic staff and men's views of online research methodology.

METHODS

(1) Website development: we combined evidence from research literature and the views of experts (n = 18) and male clinic users (n = 43); (2) feasibility RCT: 159 heterosexually active men were recruited from three sexual health clinics and were randomised by computer to the Men's Safer Sex website plus usual care (n = 84) or usual clinic care only (n = 75). Men were invited to complete online questionnaires at 3, 6, 9 and 12 months, and sexually transmitted infection (STI) diagnoses were recorded from clinic notes at 12 months; (3) health economic evaluation: we investigated the impact of using different questionnaires to calculate utilities and QALYs (the EQ-5D-3L and SQoL questionnaire), and compared different methods to collect resource use; and (4) qualitative evaluation: thematic analysis of interviews with 11 male trial participants and nine clinic staff, as well as free-text comments from online outcome questionnaires.

RESULTS

(1) Software errors and clinic Wi-Fi access presented significant challenges. Response rates for online questionnaires were poor but improved with larger vouchers (from 36% with £10 to 50% with £30). Clinical records were located for 94% of participants for STI diagnoses. There were no group differences in condomless sex with female partners [incidence rate ratio (IRR) 1.01, 95% confidence interval (CI) 0.52 to 1.96]. New STI diagnoses were recorded for 8.8% (7/80) of the intervention group and 13.0% (9/69) of the control group (IRR 0.75, 95% CI 0.29 to 1.89). (2) Health-care resource data were more complete using patient files than questionnaires. The probability that the intervention is cost-effective is sensitive to the source of data used and whether or not data on intended pregnancies are included. (3) The pilot RCT fitted well around clinical activities but 37% of the intervention group did not see the Men's Safer Sex website and technical problems were frustrating. Men's views of the Men's Safer Sex website and research procedures were largely positive.

CONCLUSIONS

It would be feasible to conduct a large-scale RCT using clinic STI diagnoses as a primary outcome; however, technical errors and a poor response rate limited the collection of online self-reported outcomes. The next steps are (1) to optimise software for online trials, (2) to find the best ways to integrate digital health promotion with clinical services, (3) to develop more precise methods for collecting resource use data and (4) to work out how to overcome barriers to digital intervention testing and implementation in the NHS.

Deploying machine learning to find out the reasons for not using condom in a questionnaire-based study of 120 patients

Context:

Even though condom offers more than 90% protection against human immunodeficiency viral infections (human immunodeficiency virus) and few sexually transmitted infections (STIs), the overall use of condom in India is low. Many studies revealed that the significant barriers for not using condom were lack of privacy in stores, cultural differences, etc.

Aims:

We intended to find out the reasons for not using condoms in patients attending the STI clinic, by using questionnaire, and had applied machine learning tool to predict those reasons for not using condoms, from the data collected.

Subjects and Methods:

A questionnaire was administered on 120 patients of age above 10 years attending the STI clinic in a tertiary hospital. From the dataset obtained, we intended to understand if the demographic profile of the candidate could predict the reasons for the avoidance of condoms during sexual activity, by using machine learning algorithm called Support Vector Machine.

Statistical Analysis Used:

MS Excel worksheet to enter the data and Support Vector Machine algorithm were used for statistical analysis.

Results:

Respondents were 53% male, 45% female, and 2% transgender. Despite the knowledge of the condoms, 68% of the patients in the study did not use condom. The majority of the patients (41%) stated that condoms were not necessary when they have sexual activity with a known and consistent partner. With machine learning, we found that the prediction accuracy was significantly more than chance (73.47% ±14%) when the feature vectors include only the response to Question 1.

Conclusions:

Results of the study identify the specific reasons for not using condom and help us in devising specific strategies to promote the condom usage. Our results from machine learning suggest that gender of the respondent is the best predictor in predicting the reason for the nonusage of condom.

Factors associated with condom use among men and women living with HIV in Lilongwe, Malawi: a cross-sectional study

BACKGROUND

Understanding the influences on condom use among men and women living with HIV is critical to tailoring sexually transmitted infection/HIV prevention efforts.

METHODS

This is a sub-analysis of a cross-sectional survey including 255 women and 220 men who were sexually active, HIV-positive, and attending HIV care visits in Lilongwe, Malawi. We estimated adjusted prevalence ratios (aPRs) to evaluate for factors associated with consistent condom use (always using condoms in the past month) and use at last coitus for men and women in separate models.

RESULTS

Among women: 38% and 55% reported consistent condom use and condom use at last coitus, respectively. For women, consistent use and use at last coitus were positively associated with the ability to refuse sex without condoms and shared decision-making compared with making the decision alone regarding condom use, and negatively associated with desire for children in the future. Consistent use also increased with longer antiretroviral therapy (ART) use (≥1 year compared with no ART use). Among men: 51% and 69% reported consistent condom use and condom use at last coitus, respectively. For men, the ability to refuse sex without condoms was associated with consistent use and use at last coitus, and believing that condoms should be used with other contraception was associated with consistent use.

CONCLUSIONS

Our findings demonstrate ongoing low condom utilisation among HIV-positive individuals, and highlight that ART and contraceptive use do not deter condom use. Efforts to increase condom utilisation must recognise individual-level factors that influence use and should focus on relationship dynamics and promotion of empowerment and self-efficacy.

Psychometric Properties of the Condom Use Barriers Scale for Adolescents

Inconsistent condom use in young people is related to the perceived barriers to their use. The psychometric properties and factor structure of the new Condom Use Barriers Scale for Adolescents (CUBS-A) are analyzed. Concurrent validity was assessed by the Attitude towards condom use subscale of the validated HIV-AS test and the percentage of condom use variable. A total of 629 Spanish adolescents whose mean age was 15.17 (SD = 1.09; 51.5% boys) participated. Exploratory factor analysis supported a 15–item instrument with four factors: negotiation skills, perceived feelings, negative aspects of condoms, and disruption of the sexual experience, which explained 41.89% of the total variance (KMO = .84; χ2 = 1071.93; p < .001). The results show high internal consistency (α = .86) and a good fit of the data to the model (NNFI = .93; CFI = .95; IFI = .95; RMSEA = .04). Its total score and most of its factors show acceptable correlation with the percentage of condom use, values that support the criterial validity (p ≤ .05). Gender differences were found in most subscales (p ≤ .001). The CUBS-A is a valid and reliable new instrument for assessing perceived barriers in adolescents for using condoms to protect themselves during sexual intercourse.

Modeling Beliefs, Attitudes, and Intentions of Condom Use Among Secondary School Students in Kenya

As in other parts of sub-Saharan Africa, youth in Kenya report low rates of condom use. Although several studies have explored reasons for the low condom use among Kenyan youth, not many have established linkages between lack of use and normative beliefs and attitudes around condoms. Using the Theory of Planned Behavior (TPB), this article examined whether beliefs and attitudes around condoms influenced intentions and actual condom use. Data for the study were restricted to 1453 sexually active youth during the last school break. Path analysis was used to examine the relationship between the TPB constructs and condom use among Kenyan youth. Results indicated a direct relationship between attitudes and condom use for male respondents and an indirect relationship between these two variables for females. Both males and females who expressed greater intentions to use condoms were significantly more likely to report they used condoms consistently. Also, male and female youth with higher perceived behavioral control were significantly more likely to have used condoms consistently. Males with friends who used condoms were significantly more likely to use condoms consistently. The findings suggest the importance of examining young people's attitudes toward condoms-in particular, those deeply rooted in misconceptions that serve to discourage safer sexual behaviors.

First Report of Gender Based Violence as a Deterrent to Methadone Access Among Females Who Use Heroin in Dar es Salaam, Tanzania

High prevalence of human immunodeficiency virus (HIV) among females who use drugs in Dar es Salaam, Tanzania, contrasts strikingly with their low enrollment in HIV risk reduction services such as methadone assisted therapy (MAT). We conducted a case-control study to examine factors associated with non-enrollment in MAT, with a focus on gender-based violence. We interviewed 202 female heroin users not enrolled in MAT as cases and 93 females enrolled in MAT. We fitted logistic regression models with MAT enrollment as the outcome of interest. The likelihood of MAT enrollment decreased upon being in a violent relationship [odds ratio (OR) 0.23; 95 % CI 0.11-0.40], with experience of discrimination by a healthcare provider (OR 0.11; 95 % CI 0.04-0.35), and having a partner who also uses drugs (OR 0.05; 95 % CI 0.01-0.26). The results indicate that violence and discrimination are major impediments to MAT enrollment, necessitating implementation of interventions to address them.

How Condom Discontinuation Occurs: Interviews With Emerging Adult Women

We have almost no data on how and when couples stop using condoms. This qualitative study investigated the process of condom discontinuation. From November 2013 to April 2014, a total of 25 women living in a college town in the Midwest, ages 18 to 25, participated in semistructured interviews centered around three domains: partner interactions, contraceptive use, and sexually transmitted infection (STI) prevention. Analysis followed a critical qualitative research orientation. Participants described actively seeking the best options to prevent pregnancy, perceiving condom discontinuation in favor of hormonal methods as a smart decision, and reported wanting to discontinue using condoms due to physical discomfort. Oftentimes, nonverbal communication around contextual instances of condom unavailability paved the way for discontinuation. Participants indicated the decision to stop using condoms was neither deliberate nor planned. Condom discontinuation rarely occurred at one point in time; instead, it was preceded by a period of occasional use. Even after participants described themselves as not using condoms, sporadic condom use was normal (typically related to fertility cycles). This study provides a more detailed understanding of how and why emerging adults negotiate condom discontinuation, thereby enhancing our ability to design effective condom continuation messages. Attention should be paid to helping emerging adults think more concretely about condom discontinuation.

Is cost a structural barrier preventing men who have sex with men accessing condoms? A systematic review

A systematic review was undertaken to determine whether cost is a structural barrier preventing men who have sex with men (MSM) accessing condoms. Studies were examined from a range of countries where condoms have been distributed free to particular populations and also those where condoms were available at a cost to the individual. The study inclusion criteria were: published between January 1990 and September 2014 inclusive; published in any language, discussed cost as a barrier to condom use, discussed cost barriers to MSM accessing condoms and included a measure of outcome. Articles were systematically extracted from MEDLINE, Embase, PyschINFO and Informat using the five search terms; Male Homosexuality, Access, Cost, Cost and Cost analysis, Condoms. Sixty-four articles were initially identified and 11 included in the final review. The included studies used cost-utility analysis, qualitative, cross-sectional, cohort or randomised control trial design. Large-scale free distribution programmes and smaller targeted programmes showed positive correlations in reducing the burden of disease from HIV and other sexually transmitted infections through eliminating the issue of cost. Decreasing the cost of condoms, and providing them for no cost, appears to increase their utilisation amongst MSM and possibly reduce the burden from HIV and other sexually transmitted infections. Inequality and stigma remain important barriers to MSM accessing and using condoms particularly in the developing world.

Resilience, tipping, and hydra effects in public health: emergent collective behavior in two agent-based models

Background

Collective health behavior often demonstrates counter-intuitive dynamics, sometimes resisting interventions designed to produce change, or even producing effects that are in the opposite direction than intended by the intervention, e.g. lowering infectivity resulting in increased infections. At other times collective health behavior exhibits sudden large-scale change in response to small interventions or change in the environment, a phenomenon often called “tipping.” I hypothesize that these seemingly very different phenomena can all be explained by the same dynamic, a type of collective resilience.

Methods

I compared two simple agent-based models of interactions in networks: a public health behavior game, in which individuals decide whether or not to adopt protective behavior, and a microbial-level game, in which three different strains of bacteria attack each other. I examined the type of networks and other conditions that support a dynamic balance, and determined what changes of conditions will tip the balance.

Results

Both models show lasting dynamic equilibrium and resilience, resulting from negative feedback that supports oscillating coexistence of diversity under a range of conditions. In the public health game, health protection is followed by free-riding defectors, followed by a rise in infection, in long-lasting cycles. In the microbial game, each of three strains takes turns dominating. In both games, the dynamic balance is tipped by lowering the level of local clustering, changing the level of benefit, or lowering infectivity or attack rate. Lowering infectivity has the surprising effect of increasing the numbers of infected individuals. We see parallel results in the microbial game of three bacterial strains, where lowering one strain’s attack rate (analogous to lowering infectivity) increases the numbers of the restrained attacker, a phenomenon captured by the phrase, “the enemy of my enemy is my friend.”

Conclusions

Collective behavior often shows a dynamic balance, resulting from negative feedback, supporting diversity and resisting change. Above certain threshold conditions, the dynamic balance is tipped towards uniformity of behavior. Under a certain range of conditions we see “hydra effects” in which interventions to lower attack rate or infectivity are self-defeating. Simple models of collective behavior can explain these seemingly disparate dynamics.

Sexuality and Reproduction in HIV-Positive Women: A Meta-Synthesis

The increased access to effective antiretroviral treatment (ART) has made HIV comparable to a chronic disease in terms of life expectancy. Needs related to sexuality and reproduction are central to overall health and well-being. An interpretative meta-synthesis was performed to synthesize and assess how HIV-positive women's experiences of sexuality and reproduction have been described in qualitative studies. A total of 18 peer-reviewed qualitative studies were included, which comprised a total of 588 HIV-positive interviewed women. The studies originated from resource-rich countries outside the Asian and African continents. The analysis, resulting in a lines-of-argument synthesis, shows that HIV infection was a burden in relation to sexuality and reproduction. The weight of the burden could be heavier or lighter. Conditions making the HIV burden heavier were: HIV as a barrier, feelings of fear and loss, whereas motherhood, spiritual beliefs, and supportive relationships made the HIV burden lighter. The findings are important in developing optimal health care by addressing conditions making the burden of HIV infection lighter to bear. In future research there is a need to focus not only on examining how HIV-positive women's sexual and relationships manifest themselves, but also on how health care professionals should provide adequate support to the women in relation to sexuality and reproduction.

Risk Indicators of Depressed Mood Among Sex-Trade Workers and Implications for HIV Risk Behaviour

OBJECTIVES

To determine the prevalence of depressed mood among people who have traded sex for money in the Saskatoon Health Region (SHR), the adjusted risk factors for depressed mood among this sample, and if depressed mood was associated with decreased self-efficacy for safe sexual practices and injection drug use.

METHODS

Two-hundred ninety-nine people who have traded sex for money were surveyed with validated instruments for measuring risk behaviours, depressed mood, and self-efficacy for safe sexual practices.

RESULTS

The sample consisted primarily of low-income, poorly educated Aboriginal women, many of whom also indicated using injection drugs. Using the 16-point score cut-off for the Center for Epidemiologic Studies Depression Scale, 84.6% of participants had depressed mood. When the cut-off score was 23 points or higher, 65.9% had depressed mood. After multivariate analysis, covariates that had an independent association with depressed mood included injecting a drug in the past 4 weeks (OR 1.59; 95% CI 1.2 to 1.8), suffering the death or permanent separation from a parent before the age of 18 (OR 2.09; 95% CI 1.05 to 4.15), and physical assault or abuse by a partner in adult life (OR 2.79; 95% CI 1.38 to 5.64). Depressed mood was associated with lower self-efficacy scores for safe sexual behaviours.

CONCLUSIONS

Our study suggests that high rates of depressed mood among people who have traded sex for money is associated with injection drug use and low self-efficacy for safe sexual health practices. These findings are important and may help explain the high rates of human immunodeficiency virus within the SHR.

Failure to Use and Sustain Male Condom Usage: Lessons Learned from a Prospective Study among Men Attending STI Clinic in Pune, India

Background

Sustained or consistent use of condoms by men remains a challenge. A study was carried out to identify factors associated with failure to use condoms consistently by men attending STD clinics in Pune, India.

Method

Among 14137 STI clinic attendees, 8360 HIV sero-negative men were enrolled in a cohort study. The changes in condom usage behavior were studied among 1284 men who returned for first scheduled quarterly follow up, 309 reported consistent condom use at the time of enrollment in the cohort. Data pertaining to heterosexual men practicing high risk behavior were analyzed to identify factors associated with change in condom use behavior using logistic regression model. Demographic, behavioral and biological factors observed to be associated with condom use were fitted in five Cox proportional hazards models to calculate hazard ratios and their 95% confidence intervals to identify independent predictors of failure to sustain condom use behavior.

Results

The univariate analysis showed that men who were 30 years or older in age (p = 0.002) and those who did not have contact female sex worker (FSW) were more likely to fail to sustain consistent condom use. However both these factors did not show significant association in multivariable analysis. Marital status and contact with Hijra (eunuch) in lifetime were associated with failure to change in their condom use behavior [AOR 0.33 (CI 0.13–0.82; p = 0.017)]. During the follow up of 2 years, 61 events (15.5 per 100 person years, 95% CI 12.3–19.5 years) of ‘failure of condom use’ were recorded despite counseling. Older age, contact with non CSW partner and presence of genital ulcer disease / discharge syndrome were significant predictors of failure to sustain condom use.

Discussion

Married monogamous older men, who report contact with sex worker and present with genital ulcer disease are at risk of failure to use condom after first exposure to voluntary HIV counseling and testing. This is a scenario of primary prevention program. Condom promotion and counseling needs to be reinforced through follow up counseling among this population.

Barriers to use contraceptive methods among rural young married couples in Maharashtra, India: Qualitative findings

Introduction

In rural India contraceptive use remains uncommon among newly married couples. non-use in rural young couples contributes to higher fertility rates.

Objectives

To identify barriers of spacing contraceptive use among young married couples in rural Maharashtra.

Methods

In-depth interviews were conducted with husbands (N=30), wives (N=20), and village health providers (N=12); additionally, 3 focus groups were conducted with mothers of husbands (N= 42 focused on understanding contraceptive use and barriers. Interviews and focus groups ranged in length from 90-120 minutes. Detailed notes taken during interviews were analysed using a grounded theory approach and the data was analysed using atlas-ti software.

Results

Major barriers to spacing contraception are: pro-natal social norms, pregnancy expectations early in marriage, to produce multiple sons, limited access to modern spacing contraceptives, family resistance to adopt contraceptives, lack of husband's involvement on family planning issues, myths, misconceptions, perceived side effects and negative attitudes toward specific contraceptives.

Conclusion

Findings highlight the intersection of norms against spacing contraception, traditional gender ideologies and lack of male involvement as major barriers to the use of contraception. Male oriented outreach programmes on family planning. Promoting gender equity should be made through health programme deliveries with special focus in rural areas.

Factors facilitating and inhibiting the use of female condoms among female university students in Durban, KwaZulu-Natal, South Africa

OBJECTIVES

The study aimed to explore the factors facilitating and inhibiting female condom use among female university students in South Africa.

METHODS

This qualitative study drew on 15 individual, in-depth interviews with female university students in Durban, South Africa.

RESULTS

The results of the study highlight several factors that facilitate and inhibit female condom use. Protection from sexually transmitted infections (including HIV/AIDS) and prevention of pregnancy facilitated use of the device among female students. In addition, students expressed positive attitudes towards the female condom and preferred it to hormonal contraceptives because it offered them dual protection. Absence of side effects and greater power and autonomy to initiate safer sex were other factors that facilitated use. Inadequate availability, partner objection, stigma, insertion difficulties and lack of awareness served as significant barriers to consistent female condom use.

CONCLUSIONS

Although the female condom can protect female students from infections and pregnancy, there are several barriers to its use. Interventions should aim to increase availability of the female condom, and male involvement should be increased to facilitate consistent use of the method.

The Hawke's Bay Condom Card Scheme: a qualitative study of the views of service providers on increased, discreet access for youth to free condoms

OBJECTIVES

The incidence of sexually transmitted infections and unplanned pregnancies in adolescence is of concern. The Hawke's Bay District Health Board, New Zealand, set up a pilot condom card scheme ('the Scheme') to allow 13- to 24-year-olds, deemed suitable for the Scheme, to access free condoms from pharmacies on presentation of a Condom Card. Our study explored the views of service providers of a pilot Condom Card Scheme.

METHODS

Qualitative interviews were conducted with 17 service providers (nurses, pharmacists, pharmacy staff) between February and April 2013.

KEY FINDINGS

Our findings showed that the Scheme was viewed positively by service providers, who indicated almost universal support for the Scheme to continue. However, participants noted a perceived lack of advertising, low number of sites for collection of condoms, lack of flexibility of the Scheme's criteria relating to who could access the scheme and issues with some pharmacy service providers, all of which led to a number of recommendations for improving the Scheme.

CONCLUSIONS

The views of service providers indicate broad support for the continuation of the Scheme. Canvassing young people's suggestions for improving the Scheme is also essential.

Intimate relationships of Devadasi sex workers in South India: An exploration of risks of HIV/STI transmission

Global literature on female sex workers suggests that being in an intimate relationship is associated with barriers to practising safe sex behaviours. Condom use within intimate relationships is often seen as a sign of infidelity and fosters mistrust which could affect longevity, trust and intimacy within partnerships. Using qualitative data from Devadasi sex workers and their intimate male partners in Bagalkot District, Karnataka, India, we examined both partners' perspectives to understand the quality and dynamics of these relationships and the factors that influence condom use in intimate relationships. Our thematic analysis of individual interviews conducted in May 2011 with 20 couples suggests that many Devadasi sex workers and their intimate partners define their relationships as 'like marriage' which reduced their motivation to use condoms. Evidence from this study suggests that active participation in sex workers' collectives (sanghas) can increase condom use, education and family planning services, among other things, and could be helpful for both Devadasis and their intimate partners to better understand and accept safer sexual practices. Our work has direct implications for designing couple-based health interventions for traditional Devadasi sex workers and their intimate partners in India.

Structural and community-level interventions for increasing condom use to prevent the transmission of HIV and other sexually transmitted infections

BACKGROUND

Community interventions to promote condom use are considered to be a valuable tool to reduce the transmission of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). In particular, special emphasis has been placed on implementing such interventions through structural changes, a concept that implies public health actions that aim to improve society's health through modifications in the context wherein health-related risk behavior takes place. This strategy attempts to increase condom use and in turn lower the transmission of HIV and other STIs.

OBJECTIVES

To assess the effects of structural and community-level interventions for increasing condom use in both general and high-risk populations to reduce the incidence of HIV and STI transmission by comparing alternative strategies, or by assessing the effects of a strategy compared with a control.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, from 2007, Issue 1), as well as MEDLINE, EMBASE, AEGIS and ClinicalTrials.gov, from January 1980 to April 2014. We also handsearched proceedings of international acquired immunodeficiency syndrome (AIDS) conferences, as well as major behavioral studies conferences focusing on HIV/AIDS and STIs.

SELECTION CRITERIA

Randomized control trials (RCTs) featuring all of the following.1. Community interventions ('community' defined as a geographical entity, such as cities, counties, villages).2. One or more structural interventions whose objective was to promote condom use. These type of interventions can be defined as those actions improving accessibility, availability and acceptability of any given health program/technology.3. Trials that confirmed biological outcomes using laboratory testing.

DATA COLLECTION AND ANALYSIS

Two authors independently screened and selected relevant studies, and conducted further risk of bias assessment. We assessed the effect of treatment by pooling trials with comparable characteristics and quantified its effect size using risk ratio. The effect of clustering at the community level was addressed through intra-cluster correlation coefficients (ICCs), and sensitivity analysis was carried out with different design effect values.

MAIN RESULTS

We included nine trials (plus one study that was a subanalysis) for quantitative assessment. The studies were conducted in Tanzania, Zimbabwe, South Africa, Uganda, Kenya, Peru, China, India and Russia, comprising 75,891 participants, mostly including the general population (not the high-risk population). The main intervention was condom promotion, or distribution, or both. In general, control groups did not receive any active intervention. The main risk of bias was incomplete outcome data.In the meta-analysis, there was no clear evidence that the intervention had an effect on either HIV seroprevalence or HIV seroincidence when compared to controls: HIV incidence (risk ratio (RR) 0.90, 95% confidence interval (CI) 0.69 to 1.19) and HIV prevalence (RR 1.02, 95% CI 0.79 to 1.32). The estimated effect of the intervention on other outcomes was similarly uncertain: Herpes simplex virus 2 (HSV-2) incidence (RR 0.76, 95% CI 0.55 to 1.04); HSV-2 prevalence (RR 1.01, 95% CI 0.85 to 1.20); syphilis prevalence (RR 0.91, 95% CI 0.71 to 1.17); gonorrhoea prevalence (RR 1.16, 95% CI 0.67 to 2.02); chlamydia prevalence (RR 0.94, 95% CI 0.75 to 1.18); and trichomonas prevalence (RR 1.00, 95% CI 0.77 to 1.30). Reported condom use increased in the experimental arm (RR 1.20, 95% CI 1.03 to 1.40). In the intervention groups, the number of people reporting two or more sexual partners in the past year did not show a clear decrease when compared with control groups (RR 0.90, 95% CI 0.78 to 1.04), but knowledge about HIV and other STIs improved (RR 1.15, 95% CI 1.04 to 1.28, and RR 1.23, 95% CI 1.07 to 1.41, respectively). The quality of the evidence was deemed to be moderate for nearly all key outcomes.

AUTHORS' CONCLUSIONS

There is no clear evidence that structural interventions at the community level to increase condom use prevent the transmission of HIV and other STIs. However, this conclusion should be interpreted with caution since our results have wide confidence intervals and the results for prevalence may be affected by attrition bias. In addition, it was not possible to find RCTs in which extended changes to policies were conducted and the results only apply to general populations in developing nations, particularly to Sub-Saharan Africa, a region which in turn is widely diverse.

Perceived behavioural control, subjective norms, attitudes and intention to use condom: a longitudinal cross-lagged design

Based on the Theory of Planned Behaviour (TPB), the purpose of this investigation was to examine the directionality of the association among condom use, intention, attitudes, subjective norms and perceived behavioural control. The present study investigated the nature of these relationships using a longitudinal cross-lagged design applied to data from a cohort of 958 randomly selected Italian adults. Using structural equation modelling, two cross-lagged panel analyses revealed reciprocal relationships between intention and attitudes and between intention and condom use. Contrary to expectations, baseline subjective norms and perceived behavioural control did not predict subsequent intention to use condom when controlled for the autoregressive effect of intention at T1 on the same variable at T2. Also, perceived behavioural control at T1 did not influence condom use at T2 after controlling for the effect of baseline intention. The possibility of reciprocity was also tested for all relations and significant results were found. The moderation effect of perceived behavioural control on the relationship between intention and condom use was not significant. The differences in age, gender and partnership status were taken into account in the analyses.

Reproductive health policy affecting low-income women: historical precedents and current need for social work action

This article provides an overview of the historical arguments surrounding reproductive health policy and current policy initiatives. Because reproductive policy itself is a vast subject matter with sometimes blurry boundaries, the struggle concerning the advent of birth control is used to illustrate the historic complexities of policy affecting such a wide array of individuals. The battle over introduction of the birth control pill is pertinent because the very same arguments are used today in debates over reproductive health policy.

Correlates of condom use among males in North Sudan

Objectives In sub-Saharan Africa countries, HIV infections are transmitted primary through heterosexual contact. Correct and consistent condom use has been promoted as a method to prevent sexually transmissible infections, including HIV. The aim of this study was to assess and determine the factors influencing condom use in Khartoum, Sudan.

MATERIALS AND METHODS

Out of the 45 voluntary counselling and testing centres in Khartoum region, 10 centres were selected. A random sample of 804 respondents aged 20-40 years was selected. Stepwise multiple logistic regression analysis was used to investigate the predictors of condom use.

RESULTS

About 12% of respondents reported using condoms consistently, 41.5% used them sporadically and 46.3% were nonusers. Most of the participants had problems with condom use (81.9%) and friends were the main source of condoms (72%). Knowledge about AIDS transmission, knowing someone who is infected with or had died of AIDS, experiencing condom problems, type of sexual partners, purchase embarrassment and education were the main predictors of condom use.

CONCLUSIONS

Condom use among the Sudanese is low. Strategies to promote condom use should focus on price support for condoms by the government, expanded private sector condom distribution and the integration of sex education in school curriculums or via frequent discussion on television.

Patterns of Caribbean Masculinities and Condom Compliance Among Males in Grenada

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.

No evidence of sexual risk compensation in the iPrEx trial of daily oral HIV preexposure prophylaxis

Objective

Preexposure prophylaxis (PrEP) with emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) reduced HIV acquisition in the iPrEx trial among men who have sex with men and transgender women. Self-reported sexual risk behavior decreased overall, but may be affected by reporting bias. We evaluated potential risk compensation using biomarkers of sexual risk behavior.

Design and methods

Sexual practices were assessed at baseline and quarterly thereafter; perceived treatment assignment and PrEP efficacy beliefs were assessed at 12 weeks. Among participants with ≥1 follow-up behavioral assessment, sexual behavior, syphilis, and HIV infection were compared by perceived treatment assignment, actual treatment assignment, and perceived PrEP efficacy.

Results

Overall, acute HIV infection and syphilis decreased during follow-up. Compared with participants believing they were receiving placebo, participants believing they were receiving FTC/TDF reported more receptive anal intercourse partners prior to initiating drug (12.8 vs. 7.7, P = 0.04). Belief in receiving FTC/TDF was not associated with an increase in receptive anal intercourse with no condom (ncRAI) from baseline through follow-up (risk ratio [RR] 0.9, 95% confidence interval [CI]: 0.6–1.4; P = 0.75), nor with a decrease after stopping study drug (RR 0.8, 95% CI: 0.5–1.3; P = 0.46). In the placebo arm, there were trends toward lower HIV incidence among participants believing they were receiving FTC/TDF (incidence rate ratio [IRR] 0.8, 95% CI: 0.4–1.8; P = 0.26) and also believing it was highly effective (IRR 0.5, 95% CI: 0.1–1.7; P = 0.12).

Conclusions

There was no evidence of sexual risk compensation in iPrEx. Participants believing they were receiving FTC/TDF had more partners prior to initiating drug, suggesting that risk behavior was not a consequence of PrEP use.

Text messaging for sexual communication and safety among African American young adults

African American young adults are at high risk of HIV infection during their lifetimes, and the male condom remains the best method of prevention. Efforts to increase condom use should address the barrier of condom negotiation. We conducted a thematic analysis of qualitative, semistructured interviews with African American young adults to examine their use of text messaging for requesting human immunodeficiency virus (HIV) or sexually transmitted infection (STI) testing and condom use within the larger context of general sexual communication using text messages. Text messaging gave participants a level of comfort and disinhibition to discuss sexual topics and negotiate sexual safety. Benefits of text messages included ease of communication, privacy, and increased ability to express condom desires. Difficulties reflected the potential relationship implications of suggesting HIV/STI testing and condom use. Condom negotiation strategies using text messages also mirrored those found to be used in face-to-face communication.

Prophylactic procurement of university students in Southern Ethiopia: stigma and the value of condom machines on campus

Introduction

Risky sexual behavior among Ethiopian university students, especially females, is a major contributor to young adult morbidity and mortality. Ambaw et al. found that female university students in Ethiopia may fear the humiliation associated with procuring condoms. A study in Thailand suggests condom machines may provide comfortable condom procurement, but the relevance to a high-risk African context is unknown. The objective of this study was to examine if the installation of condom machines in Ethiopia predicts changes in student condom uptake and use, as well as changes in procurement related stigma.

Methods

Students at a large urban university in Southern Ethiopia completed self reported surveys in 2010 (N  = 2,155 surveys) and again in 2011 (N =  2,000), six months after the installation of condom machines. Mann-Whitney and Chi-square tests were conducted to evaluate significant changes in student sexual behavior, as well as condom procurement and associated stigma over the subsequent one year period.

Results

After installing condom machines, the average number of trips made to procure condoms on-campus significantly increased 101% for sexually active females and significantly decreased 36% for sexually active males. Additionally, reports of condom use during last sexual intercourse showed a non-significant 4.3% increase for females and a significant 9.0% increase for males. During this time, comfort procuring condoms and ability to convince sexual partners to use condoms were significantly higher for sexually active male students. There was no evidence that the condom machines led to an increase in promiscuity.

Conclusions

The results suggest that condom machines may be associated with more condom procurement among vulnerable female students in Ethiopia and could be an important component of a comprehensive university health policy.

The context of condom use among young adults in the Philippines: implications for HIV prevention

We examine current perceptions and constraints surrounding condom use among young adults in the Philippines to garner a deeper contextual understanding of this aspect of HIV prevention within Filipino society. Through thematic analysis of focus group data, we found three broad themes, all of which include societal and individual barriers to using condoms. The findings may provide insight for similar settings in which religion has a strong influence on society. To strengthen HIV prevention efforts in such settings, we suggest that the development of strategies to address these constraints and promote healthy sexuality in young adults is essential.

Condom use as situated in a risk context: women's experiences in the massage parlour industry in Vancouver, Canada

Investigation into condom use in sex work has aroused interest in health promotion and illness prevention. Yet there remains a dearth of inquiry into condom use practices in the indoor sex industry, particularly in North America. We performed a thematic analysis of one aspect of the indoor sex work by drawing on data from a larger mixed-methods study that investigated women's health issues in the massage parlour industry in Vancouver, Canada. Using a risk context framework, condom use was approached as a socially situated practice constituted by supportive and constraining dynamics. Three analytic categories were identified: (1) the process of condom negotiation, (2) the availability of condoms and accessibility to information on STI and (3) financial vulnerability. Within these categories, several supportive dynamics (industry experience and personal ingenuity) and constraining dynamics (lack of agency support, client preferences, limited language proficiency and the legal system) were explored as interfacing influences on condom use. Initiatives to encourage condom use must recognise the role of context in order to more effectively support the health-promoting efforts of women in sex work.

A comparative analysis of predictors of teenage pregnancy and its prevention in a rural town in Western Nigeria

Introduction

Teenagers younger than 15 are five times more likely to die during pregnancy or childbirth than women in their twenties and mortality rates for their infants are higher as well. This study was therefore designed to determine the recent prevalence and identify factors associated with teenage pregnancy in a rural town in Nigeria.

Methods

This study is an analytical comparative cross-sectional study. A total sample of all pregnant women attending the primary health care in Sagamu local government area, Ogun State within a 2 months period were recruited into the study.

Results

A total of 225 pregnant women were recruited into the study. The prevalence of teenage pregnancy was 22.9%. Teenagers [48.2%] reported more unwanted pregnancy when compared with the older age group [13.6%] [OR = 5.91, C.I = 2.83-12.43]. About half 33 [41.1%] of the teenage pregnant women and 28.6% of the older pregnant women did not know how to correctly use condom to prevent pregnancy [OR = 0.57, C.I = 0.29-1.13]. Predictors of teenage pregnancy were low social class (OR = 2.25, C.I = 1.31-3.85], Religion (OR = 0.44, C.I = 0.21-0.91], being a student (OR = 3.27, C.I = 1.02-10.46) and having a white collar job (OR = 0.09, C.I = 0.01-0.81).

Conclusion

The study concludes that employment in an established organization (white collar job) is highly protective against teenage pregnancy while students are becoming increasingly prone to early pregnancy. Government should structure employment in low income countries in such a way as to give a quota to adolescents who are unable to continue their education.

Reconciling religious identity and reproductive practices: the Church and contraception in Poland

BACKGROUND AND OBJECTIVE

After the fall of state socialism in Poland in 1989, a Catholic-nationalist government assumed power. The new political power of the Catholic Church resulted in severe restrictions on family planning (FP) services. Yet, Poland's fertility rate declined sharply, suggesting that women are controlling their fertility despite restrictions. This study examined the Church's influence on women's contraceptive decisions, and how women reconcile religious teachings with their contraceptive use.

METHODS

We conducted a mixed-methods study, including a cross-sectional survey and qualitative interviews, in Gdańsk, Poland with sexually active women aged 18-40. The quantitative sample included 418 respondents; the qualitative sample included 49 respondents.

RESULTS

Despite restrictions on FP services, modern contraceptive use among our sample was 56%, up from 19% in 1991. Catholicism played a relatively small role in respondents' contraceptive decisions; though 94.2% of respondents were Catholic, 79% reported that the Church had little or no influence on reproductive decisions. Women's explanations for how they reconcile their reproductive practices with Catholicism included using elements of religion to support contraceptive use, prioritising responsibility for family and financial considerations over the Church's prohibitions, and challenging the Church's credibility in FP matters.

CONCLUSIONS

Our findings underscore women's struggles under post-socialist reproductive policies that limit FP access. Despite religious, political, and economic obstacles, contraceptive use has increased dramatically, indicating that FP is a high priority for women in Poland. Policies should respond to women's needs. Comprehensive, state-sponsored FP and sex education are urgently needed and the state should legitimise such services.

Predictors of condom use and refusal among the population of Free State province in South Africa

BACKGROUND

This study investigated the extent and predictors of condom use and condom refusal in the Free State province in South Africa.

METHODS

Through a household survey conducted in the Free Sate province of South Africa, 5,837 adults were interviewed. Univariate and multivariate survey logistic regressions and classification trees (CT) were used for analysing two response variables 'ever used condom' and 'ever refused condom'.

RESULTS

Eighty-three per cent of the respondents had ever used condoms, of which 38% always used them; 61% used them during the last sexual intercourse and 9% had ever refused to use them. The univariate logistic regression models and CT analysis indicated that a strong predictor of condom use was its perceived need. In the CT analysis, this variable was followed in importance by 'knowledge of correct use of condom', condom availability, young age, being single and higher education. 'Perceived need' for condoms did not remain significant in the multivariate analysis after controlling for other variables. The strongest predictor of condom refusal, as shown by the CT, was shame associated with condoms followed by the presence of sexual risk behaviour, knowing one's HIV status, older age and lacking knowledge of condoms (i.e., ability to prevent sexually transmitted diseases and pregnancy, availability, correct and consistent use and existence of female condoms). In the multivariate logistic regression, age was not significant for condom refusal while affordability and perceived need were additional significant variables.

CONCLUSIONS

The use of complementary modelling techniques such as CT in addition to logistic regressions adds to a better understanding of condom use and refusal. Further improvement in correct and consistent use of condoms will require targeted interventions. In addition to existing social marketing campaigns, tailored approaches should focus on establishing the perceived need for condom-use and improving skills for correct use. They should also incorporate interventions to reduce the shame associated with condoms and individual counselling of those likely to refuse condoms.

Sexual risk history and condom use among people living with HIV/AIDS in Ogun State, Nigeria

INTRODUCTION

The majority of human immunodeficiency virus (HIV) infections are acquired through unprotected sex between partners; only male or female condoms can reduce the chances of infection with HIV during a sexual act.

AIM

This study was therefore designed to describe sexual risk history and identify factors associated with condom use among people living with HIV/acquired immunodeficiency syndrome (AIDS) (PLWHAs) in Ogun State, Nigeria.

MAIN OUTCOME MEASURES

Main outcome measures are sexual and HIV risk history, safe sex practices, and condom use.

METHODS

This study is an analytical cross-sectional study. A total sample of all people living with HIV/AIDS attending secondary health facilities in Ogun State were recruited into the study.

RESULT

A total of 637 were interviewed; median age at first sexual intercourse among the study participants was 19 years (mean age = 18.95, standard deviation [SD] = 4.148) with a median of two lifetime sexual partners (mean = 3.22, SD = 3.57). Majority (71.4%) of the respondents had not been diagnosed with a sexually transmitted infection other than HIV. Precisely 47.7% of men and 52.3% of women had two or more sexual partners in the last 6 months. Men were statistically significantly more likely to have multiple sexual partners when compared with women (P = 0.00). Significantly more women (69.8%) than men (30%) had sexual partners whose HIV status they did not know (P = 0.006). Predictors of condom use were individuals who had multiple sexual partners (odds ratio [OR] = 1.41, confidence interval [CI] = 1.05-1.83) and married (OR = 3.13, CI = 1.15-8.51) with higher level of education (OR = 2.78, CI = 1.39-5.79), with knowledge of partner's serostatus (OR = 2.53, CI = 1.50-4.28), and awareness of reinfection (OR = 1.90, CI = 1.22-2.95).

CONCLUSION

The study indicates that the establishment of effective safe sex practices and condom use behavior among PLWHAs in low-income countries such as the study population requires adequate health education on the transmission of HIV/AIDS and the understanding of the dynamics of family life and gender issues.

Conversation and compliance: role of interpersonal discussion and social norms in public communication campaigns

This study explores the role of interpersonal discussion and social norms in a public health campaign, the BBC Condom Normalization Campaign, designed to promote conversation and change the public perception of condom use in India. Drawing upon the integrative model of behavioral prediction, attitudes, self-efficacy, subjective norms, and descriptive norms were predicted to relate to behavioral intentions to use condoms. It is important to note that the valence of discussion was hypothesized to relate to each of these more proximal predictors. The authors used structural equation modeling to test the model on 3 separate samples of Indian men between the ages of 15 and 49 years: (a) high-risk men who had sex with nonspouses; (b) low-risk, sexually inactive, unmarried men; and (c) low-risk, monogamous, married men. Results were similar for low- and high-risk audiences, with valence of discussion about condoms predicting condom-related attitudes, self-efficacy, and subjective and descriptive social norms with respect to condom use, which, in turn, predicted behavioral intent to use condoms. These findings underscore the need to take not only the frequency but also the valence of interpersonal discussion into account when assessing the effect of health campaigns. Implications for theory and design of future public communication campaigns are explored.

'It's not about money, it's about my health': determinants of participation and adherence among women in an HIV-HSV2 prevention trial in Johannesburg, South Africa

High levels of adherence in clinical trials are essential for producing accurate intervention efficacy estimates. Adherence to clinical trial products and procedures is dependent on the motivations that drive participants. Data are presented to document reasons for trial participation and adherence to daily aciclovir for HSV-2 and HIV-1 genital shedding suppression among 300 HIV-1/HSV-2 seropositive women in South Africa. In-depth interviews after exit from the trial with 31 randomly selected women stratified by age and time since HIV diagnosis confirmed high levels of adherence measured during the trial. Main reasons for trial participation were related to seeking high-quality health care, which explains high levels of adherence in both study arms. Concerns that women would abuse reimbursements, fabricate data, and share or dump pills were not corroborated. Altruism is not a primary motivator in these settings where access to quality services is an issue. This study provides further evidence that good adherence of daily medication is possible in developing countries, particularly where study activities resonate with participants or fill an unmet need.

Efficacy of behavioral interventions to increase condom use and reduce sexually transmitted infections: a meta-analysis, 1991 to 2010

OBJECTIVE

In the absence of an effective HIV vaccine, safer sexual practices are necessary to avert new infections. Therefore, we examined the efficacy of behavioral interventions to increase condom use and reduce sexually transmitted infections (STIs), including HIV.

DESIGN

Studies that examined a behavioral intervention focusing on reducing sexual risk, used a randomized controlled trial or a quasi-experimental design with a comparison condition, and provided needed information to calculate effect sizes for condom use and any type of STI, including HIV.

METHODS

Studies were retrieved from electronic databases (eg, PubMed, PsycINFO) and reference sections of relevant papers. Forty-two studies with 67 separate interventions (N = 40,665; M age = 26 years; 68% women; 59% Black) were included. Independent raters coded participant characteristics, design and methodological features, and intervention content. Weighted mean effect sizes, using both fixed-effects and random-effects models, were calculated. Potential moderators of intervention efficacy were assessed.

RESULTS

Compared with controls, intervention participants increased their condom use [d+ = 0.17, 95% confidence interval (CI) = 0.04, 0.29; k = 67], had fewer incident STIs (d+ = 0.16, 95% CI = 0.04, 0.29; k = 62), including HIV (d+ = 0.46, 95% CI = 0.13, 0.79; k = 13). Sample (eg, ethnicity) and intervention features (eg, skills training) moderated the efficacy of the intervention.

CONCLUSIONS

Behavioral interventions reduce sexual risk behavior and avert STIs and HIV. Translation and widespread dissemination of effective behavioral interventions are needed.

Behavioral interventions to reduce the transmission of HIV infection among sex workers and their clients in high-income countries

BACKGROUND

Interventions to change behaviour among sex workers and their clients have been identified as a strategy to reduce HIV transmission. However, there has been no systematic review that has examined and summarized their effects.

OBJECTIVES

To identify and evaluate the effects of the studies performed on behavioural interventions to reduce the transmission of HIV infection among sex workers and their clients in high-income countries.

SEARCH METHODS

Electronic searches were undertaken using MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and other databases between January 1980 and July 2010. Experts in the field were contacted to locate any other studies.

SELECTION CRITERIA

Randomised controlled trials or specified quasi-experimental designs with comparison groups that examined the effects of behavioural interventions aimed at reducing the risk of HIV or sexually transmitted infections (STIs) transmission among sex workers in high-income countries. We reviewed studies for outcome relevance and methodological rigor.

DATA COLLECTION AND ANALYSIS

Two reviewers independently applied the inclusion criteria to potential studies, and any disagreements were resolved by discussion. Studies were assessed for completeness of reporting and extracted data.

MAIN RESULTS

A total of four studies were included, comprising two randomised controlled trials and two quasi-experimental pretest-posttest trials with control groups involving 1795 participants. No trials reported HIV prevalence/incidence as outcomes.Overall, the effects of behavioural interventions for sex workers in high-income countries on STI incidence did not differ significantly among two studies using a random effects model (risk ratio (RR) 0.46, 95% confidence interval (CI) 0.11 to 1.98). Only one study found that the self-reported STI prevalence in clients of female sex workers was statistically significant (RR 0.09, 95%CI 0.01 to 0.72, P=0.02). There was no significant difference after behavioural intervention for condom use. Two studies demonstrated the effectiveness of intervention for knowledge of HIV transmission among sex workers (RR 1.82, 95%CI 1.55 to 2.14) and clients of sex workers (RR 1.93, 95%CI 1.46 to 2.55).

AUTHORS' CONCLUSIONS

There is limited evidence from randomised controlled trials for the effectiveness of behavioural interventions to reduce the transmission of HIV infection among sex workers and their clients in high-income countries. Further randomised controlled trials are very likely to have important impacts on our confidence in the estimates of the effects, and are likely to change the estimates for effective interventions with outcomes of HIV incidence or prevalence and a variety of different settings among sex workers and their clients in high-income countries. Randomised controlled trials that test for the identification of effective interventions for HIV prevention with outcomes of biological endpoints, such as HIV incidence or prevalence, are needed for these neglected populations. More research is also needed for male or transgender sex workers and their clients in high-income countries.

A qualitative study of barriers to consistent condom use among HIV-1 serodiscordant couples in Kenya

This study explored barriers to consistent condom use among heterosexual HIV-1 serodiscordant couples who were aware of the HIV-1 serodiscordant status and had been informed about condom use as a risk reduction strategy. We conducted 28 in-depth interviews and 9 focus group discussions among purposively selected heterosexual HIV-1 serodiscordant couples from Thika and Nairobi districts in Kenya. We analyzed the transcribed data with a grounded theory approach. The most common barriers to consistent condom use included male partners' reluctance to use condoms regardless of HIV-1 status coupled with female partners' inability to negotiate condom use, misconceptions about HIV-1 serodiscordance, and desire for children. Specific areas of focus should include development of skills for women to effectively negotiate condom use, ongoing information on HIV-1 serodiscordance and education on safer conception practices that minimize risk of HIV-1 transmission.

A hot-melt extruded intravaginal ring for the sustained delivery of the antiretroviral microbicide UC781

Microbicide intravaginal rings (IVRs) are a promising woman-controlled strategy for preventing sexual transmission of human immunodeficiency virus (HIV). An IVR was prepared and developed from polyether urethane (PU) elastomers for the sustained delivery of UC781, a highly potent nonnucleoside reverse transcriptase inhibitor of HIV-1. PU IVRs containing UC781 were fabricated using a hot-melt extrusion process. In vitro release studies of UC781 demonstrated that UC781 release profiles are loading dependent and resemble matrix-type, diffusion-limited kinetics. The in vitro release methods employed over predicted the in vivo release rates of UC781 in rabbits. Accelerated stability studies showed good chemical stability of UC781 in prototype formulations, but surface crystallization of UC781 was observed following long-term storage at higher UC781 loadings, unless formulated with a polyvinylpyrrolidone/glycerol surface coating. Mechanical stability testing of prototype rings showed moderate stiffening upon storage. The PU and UC781 had minimal to no impact on viability, tissue integrity, barrier function, or cytokine expression in the tissue irritation model, and UC781 was shown to be delivered to and permeate through this tissue construct in vitro. Overall, UC781 was formulated in a stable PU IVR and provided controlled release of UC781 both in vitro and in vivo.

Gender, Alcohol Consumption Patterns, and Engagement in Sexually Intimate Behaviors Among Adolescents and Young Adults in Nha Trang, Viet Nam

A randomly selected cross-sectional survey was conducted with 880 youth (16 to 24 years) in Nha Trang City to assess relationships between alcohol consumption and sexual behaviors. A timeline followback method was employed. Chi-square, generalized logit modeling and logistic regression analyses were performed. Of the sample, 78.2% male and 56.1% female respondents ever consumed alcohol. Males reporting sexual behaviors (vaginal, anal, oral sex) had a significantly higher calculated peak BAC of 0.151 compared to 0.082 for males reporting no sexual intimacy (p < .0001). Females reporting sexual behaviors had a peak BAC of 0.072 compared to 0.027 for those reporting no sexual intimacy (p = .016). Fifty percent of (33/66) males and 30.4% (7/23) females report event specific drinking and engagement in sexual behaviors. Males reporting 11+ drinks in 30 days had more sexual partners than those reporting 1 to 10 drinks (p = .037). Data suggest different physical and psychosocial mediators between alcohol consumption and sexual behaviors by gender.
