Condom availability for HIV/STD prevention

Vaginal microecology and its role in human papillomavirus infection and human papillomavirus associated cervical lesions

The vaginal microecology comprises the vaginal microbiome, immune microenvironment, vaginal anatomy, and the cervicovaginal fluid, which is rich in metabolites, enzymes, and cytokines. Investigating its role in the female reproductive system holds paramount significance. The advent of next-generation sequencing enabled a more profound investigation into the structure of the vaginal microbial community in relation to the female reproductive system. Human papillomavirus infection is prevalent among women of reproductive age, and persistent oncogenic HPV infection is widely recognized as a factor associated with cervical cancer. Extensive previous research has demonstrated that dysbiosis of vaginal microbiota characterized by a reduction in Lactobacillus species, heightens susceptivity to HPV infection, consequently contributing to persistent HPV infection and the progression of cervical lesion. Likewise, HPV infection can exacerbate dysbiosis. This review aims to provide a comprehensive summary of current literatures and to elucidate potential mechanisms underlying the interaction between vaginal microecology and HPV infection, with the intention of offering valuable insights for future clinical interventions.

Receipt and use of free condoms among US men who have sex with men

OBJECTIVES

Despite large public investments in condom distribution programs for HIV prevention among men who have sex with men (MSM), few evaluations have documented the reach of condom distribution programs or whether free condoms distributed to MSM are actually used. Among MSM recruited from social networking and dating websites, we examined the proportion who reported acquiring and using free condoms, and associations between select characteristics and reported acquisition and use of free condoms.

METHODS

We used baseline data from a prospective, online cohort of U.S. MSM. Participants reported acquiring free condoms in the 12 months before interview and, for those who acquired condoms and had anal intercourse, use of the free condoms they acquired. We used multivariable log binomial regression models to describe factors associated with self-reported acquisition and use of condoms.

RESULTS

Of the 2,893 men in the analytic sample, 1,701 (59%) reported acquiring free condoms in the past year. Acquisition of free condoms was higher for men who were younger, more educated, recently tested for HIV, and had higher numbers of sex partners. Seventy-three percent of men who acquired free condoms reported using them; use was higher for men who were black, had been recently tested for HIV, and reported greater numbers of sex partners.

CONCLUSIONS

Most MSM in our online sample reported receiving free condoms, and most who acquired free condoms reported using them. These data suggest that condom distribution programs have reasonable reach and utility as part of a comprehensive package of HIV prevention interventions for U.S. MSM.

Condom access in San Antonio, Texas: the "three A's" and HIV/STI incidence

Condoms are highly effective at reducing STI transmission. Access is a critical precursor to use. This socio-ecologic study operationalizes the concept of condom access by defining it in terms of availability, affordability, and affect, and explores the relationship between these and STI incidence. Three pairs of zip codes, each with similar demographics but different Chlamydia and HIV incidence rates, were identified. Supermarkets, convenience stores, and pharmacies (N = 102) were evaluated for the three A's. Nonparametric methods were used to compare the moderate-Chlamydia areas to the high-incidence areas. High-Chlamydia areas were significantly less likely to have 12-packs available compared to moderate-Chlamydia areas. Prices averaged over $1 per condom and did not vary by incidence. High-incidence areas were significantly less likely to allow patrons to select condoms unassisted. High-HIV areas placed more positively-connoted items near condoms. Improving these factors may improve condom acquisition and in turn reduce STI and HIV incidence rates.

Condom access: Associations with consistent condom use among female sex workers in two northern border cities of Mexico

To determine whether condom access is associated with consistent condom use among female sex workers (FSWs) in Tijuana and Ciudad Juarez, between 2004 and 2006 we administered a questionnaire to 924 FSWs who reported unprotected sex with a client in the past 2 months. Of these women, 43% reported consistent ("often" or "always") condom use, 74% said condoms were available, and 38% reported having access to free condoms. In a logistic regression, factors positively associated with consistent condom use were condom availability (adjusted odds ratio [AOR] = 2.00; 95% confidence interval [CI]: 1.32-3.03), condom affordability (AOR = 1.72; 95% CI: 1.25-2.38) and self-efficacy (AOR = 2.16; 95% CI: 1.54-3.04). Factors inversely associated with consistent condom use included poor financial status (AOR = 0.65; 95% CI: 0.47-0.90), methamphetamine use (AOR = 0.58; 95% CI: 0.40-0.83), alcohol use (AOR = 0.68; 95% CI: 0.49-0.96), and recent injection drug use (AOR = 0.62; 95% CI: 0.39-0.97). While increased condom availability may improve condom use among FSWs in general, interventions to broaden condom use among lower income and drug-using FSWs are critically needed.

Effects of structural intervention on increasing condom availability and reducing risky sexual behaviours in gay bathhouse attendees

The study purpose was to evaluate the effectiveness of a structural intervention in reducing unprotected sexual behaviours, increasing condom accessibility and their relationship to the prevalence of HIV infection and sexually transmitted infections (STIs) in gay bathhouse attendees. A quasi-experimental study with a non-equivalent control group for comparison was conducted at nine gay bathhouses in Taiwan from 2004 to 2006. A structural intervention designed to increase condom distribution and accessibility inside the bathhouses was implemented at one bathhouse in each city. Bathhouse attendees were invited to complete a questionnaire and to be screened for HIV infection and STIs. Of 632 study participants, 270 were surveyed six months after the intervention was conducted. At the time of follow-up after controlling for baseline data, patrons attending bathhouses for which intervention was performed were more likely to report accessing condoms inside bathhouses than those attending control bathhouses (92.6% versus 81.3%, P = 0.016), and condoms were more likely to be available at the reception desk of the bathhouse entrance (87.5% in intervention bathhouses versus 69.4% in control, P = 0.047). In a multivariate analysis adjusted for age, access to condoms inside bathhouses (adjusted odds ratio (AOR): 4.35; 95% confidence interval (CI): 1.48-12.78) and attendance at bathhouses with intervention (AOR: 2.07; 95% CI: 1.07-3.97) were independently associated with consistent condom use during anal intercourse. There were no significant differences in the prevalences of HIV infection and STIs at the six-month follow-up. Bathhouses with structural intervention were associated with consistent condom use during anal intercourse among bathhouse patrons. Our findings highlight the importance of extension of condom distribution inside the bathhouses to increase condom use among bathhouse patrons.

Condom availability inTaiwanese gay bathhouses: the right things in the wrong places

Gay bathhouses were identified as public venues where men having sex with men are more likely to engage in risky sexual behaviors. This study applied Binson and Woods's (Journal of Homosexuality, 44, 2003) theoretical framework of risk environment/bathhouse setting to (a) describe four domains of bathhouse environments, (b) investigate condom availability in bathhouses, and (c) identify barriers of condom distribution. An ethnographic study was conducted at eight gay bathhouses in Taiwan, including environmental observations, interviews of 16 staff members, and self-administered questionnaires of 409 bathhouse patrons. Condoms were provided upon request in eight bathhouses. Environmental observations showed a poor match between the places where condoms were distributed and where men had sex. Cost and police harassment were two barriers of condom distribution in bathhouses. Our findings highlight the importance of the extension of condom distribution at places where men have sex in gay bathhouses.

Condom acquisition and preferences within a sample of sexually active gay and bisexual men in the southern United States

Health departments, community-based organizations (CBOs), and AIDS service organizations (ASOs) in the United States and abroad distribute large quantities of free condoms to sexually active individuals; however, little is known about where individuals who use condoms actually acquire them. This community-based participatory research (CBPR) study was designed to identify factors associated with the use of free condoms during most recent anal intercourse among self-identifying gay and bisexual men who reported condom use. Data were collected using targeted intercept interviewing during North Carolina Pride Festival events in Fall 2006, using the North Carolina Condom Acquisition and Preferences Assessment (NC-CAPA). Of the 606 participants who completed the assessment, 285 met the inclusion criteria. Mean age of participants was 33 (+/-10.8) years. The sample was predominantly white (80%), 50% reported being single or not dating anyone special, and 38% reported the use of free condoms during most recent anal intercourse. In multivariable analysis, participants who reported using free condoms during most recent anal sex were more likely to report increased age; dating someone special or being partnered; and having multiple male sexual partners in the past 3 months. These participants were less likely to report ever having had a sexually transmitted disease. Despite being in the third decade of the HIV epidemic, little is known about condom acquisition among, and condom preferences of, gay and bisexual men who use condoms. Although more research is needed, our findings illustrate the importance of free condom distribution.

Evaluation of two school-based HIV prevention interventions in the border city of Tijuana, Mexico

This research project examined the individual and combined effectiveness of an HIV prevention workshop and a free condom distribution program in four high schools in Tijuana, Mexico. Adolescents (N = 320) completed baseline measures on sexual practices and theoretical correlates and participated in a two-part study. In Study 1, students were randomly assigned to an HIV prevention workshop or a control condition, with a 3-month follow-up assessment. Results indicate three significant workshop benefits regarding HIV transmission by altering sexual initiation, access to condoms, and traditional beliefs regarding condoms. In Study 2, we set up a condom distribution program at two of the participating schools, and students completed a 6-month follow-up assessment. Results indicate that exposure to the workshop followed by access to the condom distribution program yielded two beneficial results for reducing HIV transmission: moderating sexual initiation and increasing condom acquisition. Access to the condom distribution program alone had no effects on behavioral and psychosocial correlates of HIV transmission. We discuss implications of these results.

"Here's what I'd do...": condom promotion strategies proposed by high-risk women in Anchorage, Alaska

Women drug users are at significant risk of sexually transmitted HIV; however, interventions aimed at increasing condom use by this population have been relatively ineffective. The authors conducted a series of focus groups with 17 current and former drug-using women to identify (a) reasons for using versus not using condoms, (b) intervention strategies they believed would be most effective at increasing condom use, and (c) previous ineffective intervention strategies. Risk of HIV, sexually transmitted diseases, and pregnancy was the main reason given for using condoms. Many factors were identified that limited condom use, including lack of availability, substance use, and cost. Participants enthusiastically endorsed condom availability and AIDS awareness interventions, and suggested that no intervention was a waste of money. The authors discuss the limitations of the suggested interventions and recommend additional research to evaluate the efficacy of these strategies.

Improving the accessibility of condoms in South Africa: the role of informal distribution

Lack of access to condoms presents a fundamental barrier to HIV prevention across most of sub-Saharan Africa. One strategy to enhance the accessibility of condoms is to promote their informal distribution outside of health facilities through existing social networks. To investigate the prevalence and practices of informal condom distribution, we administered a questionnaire to individuals procuring condoms at 12 public health facilities in four regions of South Africa. Of the 554 individuals interviewed, 269 (48%) reported either giving or receiving condoms informally in the month before the study. In multivariate analysis, reporting informal condom distribution was associated with increased education, male gender, multiple sex partners and recent condom use. The specific practices involved in giving or receiving condoms differed between males and females, with women more likely to involve family members and men more likely to involve friends. These results indicate that informal condom distribution is surprisingly common among individuals procuring public sector condoms in South Africa, and begin to suggest the gendered nature of informal condom distribution networks. While these findings require confirmation in other populations, the practices of informal condom distribution described here provide an excellent opportunity for enhancing condom accessibility and delivering other interventions for HIV prevention.

Sexually transmitted infection. A challenge for nurses working with adolescents

Sexually active adolescents have high rates of STIs and many barriers to prevention and treatment because of developmental immaturity, difficulty with access to health care, and need for confidential care. Serious health consequences of STIs may occur many years after infection, further compounding adolescents' ability to link cause and effect. Nurses who are committed to the challenge of providing services for adolescents to prevent STIs can help by providing access to confidential care and promoting sexual health. High-risk youth require intensive preventive efforts. Nurses are in an ideal position to meet this challenge in their roles as providers, counselors, and sexuality educators in individual health care encounters and in prevention programs in clinics, schools, and community centers. Effective STI prevention programs should apply theories of behavior change, incorporate adolescents' attitudes and beliefs, and solicit input from the adolescents themselves.

The impact of the work environment on condom use among female bar workers in the Philippines

The purpose of this research is to examine how condom use is affected by specific aspects of the work environment: (1) social-structural and environmental influences and constraints, (2) mandatory condom use policy, and (3) the level of social influence and reinforcement between manager and employee. A total of 1,340 bar workers and 308 nonestablishment freelance workers comprise the study group. In establishments where a condom use policy exists, female bar workers were 2.6 times more likely to consistently use condoms during sexual intercourse compared with establishments that do not have such a policy in place. The results suggest a need for the development of comprehensive educational policies in all entertainment establishments, including regular meetings with employees, reinforcing attendance at the Social Hygiene Clinic, promoting AIDS awareness, making condoms available in the workplace, and mandating 100% condom use behavior among all employees.
