Value of consistent condom use: a study of sexually transmitted disease prevention among African American adolescent females

Evaluating the independent influence of sexual transmission on HBV infection in China: a modeling study

Background

The long-term impact of sexual transmission on the hepatitis B virus (HBV) infection in China remains unclear. This study aims to estimate the independent influence of sexual transmission on HBV infection.

Methods

Based on the natural history of HBV infection and three national serosurvey data of hepatitis B in China, we developed an age- and sex-specific discrete model to describe the transmission dynamics of HBV. The initial conditions of the model were determined according to the age- and sex-specific national serosurvey data in 1992. Based on the national survey data of hepatitis B in 1992 and 2006, by using the Markov Chain Monte Carlo (MCMC) method, we estimated the age- and sex-specific seroclearance rates of hepatitis B surface antigen (HBsAg) and the horizontal transmission rates as well as their 95% confidence intervals (CI). Then we used the age- and sex-specific national serosurvey data of hepatitis B in 2014 to test the accuracy of our model-based estimation. Finally, we evaluated the independent impact of sexual transmission on HBV infection and discussed the long-term effect of promotion of condom use in China.

Results

We estimated that the annual rates of HBsAg seroclearance for males and females aged 1–59 years were respectively 1.04% (95% CI, 0.49–1.59%) and 1.92% (95% CI, 1.11–2.73%). Due to sexual transmission, in 2014, the total number of chronic HBV infections in people aged 0–100 years increased 292,581, of which males increased 189,200 and females increased 103,381. In 2006, the acute HBV infections due to sexual transmission accounted for 24.76% (male: 31.33%, female: 17.94%) and in 2014, which accounted for 34.59% (male: 42.93%, female: 25.73%). However, if the condom usage rate was increased by 10% annually starting in 2019, then compared with current practice, the total number of acute HBV infections from 2019 to 2035 would be reduced by 16.68% (male: 21.49%, female: 11.93%). The HBsAg prevalence in people aged 1–59 years in 2035 would be reduced to 2.01% (male: 2.40%, female: 1.58%).

Conclusions

Sexual transmission has become the predominant route of acute HBV infection in China, especially for men. The promotion of condom use plays a significant role in reducing the cases of acute HBV infection.

Attitudes toward HIV testing, awareness of HIV campaigns, and using social networking sites to deliver HIV testing messages in the age of social media: a qualitative study of young black men

This study assessed attitudes toward HIV and awareness of previous HIV prevention campaigns among young black men in the United States of America (USA). The study also ascertained the appropriateness of HIV testing messages for young black men and explored the use of social networking sites to deliver HIV testing messages for social media marketing campaigns. Nineteen (n = 19) black male college students attending a public university in Atlanta, GA, USA from September 2016 to October 2016 participated in three focus groups. The focus groups consisted of a group interview querying experiences with HIV and STI testing, awareness of HIV campaigns, solicited feedback on campaign messages and the use of social networking sites to deliver messages. Data analysis involved the grounded theory approach to identify emergent themes. Fear, stigma and low risk perception were discussed as barriers to HIV testing. HIV prevention, social support and new sexual partners were discussed as reasons for testing. There was a general lack of awareness of existing HIV testing campaigns. Messaging with a universal appeal and disseminated through Twitter, Instagram and Snapchat may counter narratives of fear, stigma and low risk perception to increase HIV testing among young black men.

Multidimensional Patterns of Sexual Risk Behavior and Psychiatric Disorders in Men with Substance Use Disorders

Previous evidence links substance use disorders (SUD) to STI/HIV risk and suggests that comorbid psychiatric disorders increase the probability to engage in sexual risk behaviors. This study had two aims: (1) to identify subgroups based on sexual risk behavior using a person-centered approach in a sample of substance users and (2) to measure the association of psychiatric and SUD with subgroup membership. We assessed 402 male adults with SUD, reporting sexual intercourse in the previous 12 months using the HIV-Risk Behavior Scale and the Mini International Neuropsychiatric Interview. Latent class analysis was performed to determine multidimensional patterns of sexual risk behaviors and multinomial logistic regression was utilized to associate classes with disorders. The three-class model showed the best fit, and the classes were labeled: Relationship-Based (31.34% of the sample), Condom-Based (39.55%), and Multiple Risks (29.10%). Controlling for age and marital status, major depressive disorders, antisocial personality disorder, and any psychiatric disorder were associated with the Multiple Risks class. Results stress the importance of developing a personalized assessment and counseling for sexual risk behaviors in individuals with SUD, particularly when they endorse criteria for comorbid psychiatric disorders. Future studies should focus on evaluating differential response to preventive interventions.

Risky sexual behavior among cannabis users: The role of protective behavioral strategies

Cannabis users tend to use condoms less often than cannabis abstainers, placing them at risk for sexually transmitted disease and unplanned pregnancies. This is especially problematic among college students, who experience such problems at especially high rates. Despite accumulating data indicating that cannabis users are less likely to use condoms, little research has identified potentially malleable cognitive vulnerability factors that may be related to condom use in this vulnerable population. Thus, the current study tested whether cannabis users believed others use condoms less often and/or whether they engaged in less condom-related protective behavior strategies (PBS) than cannabis abstainers and whether cannabis use status was indirectly related to condom use via these vulnerability factors. Among 214 college students (64 past-month cannabis users), cannabis users engaged in less PBS (although cannabis use was unrelated to normative beliefs). Cannabis use status was indirectly related to condom use via PBS and cannabis use status was unrelated to condom use after controlling for PBS. Results highlight the importance of PBS use among cannabis users, a group at particular risk for risky sexual behaviors.

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.

"Jimmy Cap Before You Tap": Developing Condom Use Messages for African American Women

This study examined which characteristics of persuasive communications are most effective in changing African American women's condom use attitudes. Focus groups were convened with 40 African American women (M_age = 25.54, SD = 4.67) to assess their opinions on current effective strategies used to promote condom use among their peers. Participants discussed effective characteristics of messaging campaigns (i.e., source, message type, channel) and how these could be used in future prevention messages. Findings revealed that making messages that are fun, catchy, and informative, delivered frequently through social media, TV, or radio by a peer or celebrity would be perceived as most effective in changing young African American women's attitudes. Other themes that emerged were that condom use is more strongly associated with pregnancy prevention than HIV prevention and that sexual partners were perceived to have negative condom use attitudes. Recommendations centered on increasing exposure of HIV prevention messages by placing messages on the Internet and including a funny phrase or jingle in the message so that it is easy to remember and could potentially serve as a conversation starter for discussing safe sex with partners.

Contextual Factors and Sexual Risk Behaviors Among Young, Black Men

Young Black men (YBM), aged 13 to 24 years, face a disproportionate burden of sexually transmitted infections (STIs). STI acquisition among YBM is due to incorrect and inconsistent condom use and is exacerbated by multiple sexual partners. Sexual and reproductive health is influenced by a complex interaction of biological, psychological, and social determinants that contribute to increased risk for STI acquisition. However, there are key social determinants of sexual health that play a major role in adolescent sexual risk-taking behaviors: gender norms, environment, peers, and families as well as a desire to impregnate a woman. Associations between contextual factors (risky environmental context, desire to impregnate a woman, and peer norms supportive of unsafe sex) and sexual risk behaviors were examined among a sample of YBM attending adolescent health clinics. This study used baseline data from a randomized controlled trial ( N = 702). Parental monitoring was also examined as an effect modifier of those associations. Sexual risk behaviors were the frequency of condomless vaginal sex, number of sexual partners within the previous 2 months, and lifetime number of sexual partners. Mean age was 19.7. In the adjusted model, peer norms was the only significant predictor for all sexual risk outcomes ( p < .05). Parental monitoring was an effect modifier for the perceived peer norms and lifetime sexual partners association ( p = .053) where the effect of peer norms on lifetime sexual partners was lower for participants with higher levels of perceived parental monitoring.

Behavioral Risk Profile of Men Who Have Sex with Men in Beijing, China: Results from a Cross-sectional Survey with Randomized Response Techniques

Background:

Human immunodeficiency virus (HIV) is spreading rapidly among men who have sex with men (MSM) in China. Anonymous questionnaires or direct interviews have been frequently used to study their behavior. The aim of the study was to describe the behavioral risk profile of the MSM in Beijing using the randomized response techniques (RRTs).

Methods:

A cross-sectional survey of sexual behavior among a sample of MSM was conducted in two HIV counseling and testing clinics in Beijing. The survey was carried out with an anonymous questionnaire containing sensitive questions on sexual behavior. To obtain the honest responses to the sensitive questions, three distinctive RRTs were used in the questionnaire: (1) Additive randomized response model for quantitative questions, (2) randomized response model for multiple choice questions, and (3) Simmons randomized response model for binomial questions. Formulae for the point estimate, variance, and confidence interval (CI) were provided for each specific model.

Results:

Using RRTs in a sample of 659 participants, the mean age at first homosexual encounter was estimated to be 21.7 years (95% CI: 21.2–22.2), and each had sex with about three (2.9, 95% CI: 2.4–3.4) male partners on average in the past month. The estimated rate for consistent condom use was 56.4% (95% CI: 50.1–62.8%). In addition, condom was estimated to be used among 80.0% (95% CI: 74.1–85.9%) of the population during last anal sex with a male partner.

Conclusions:

Our study employed RRTs in a survey containing questions on sexual behavior among MSM, and the results showed that RRT might be a useful tool to obtain truthful feedback on sensitive information such as sexual behavior from the respondents, especially in traditional Chinese cultural settings.

Differences in correlates of condom use between young adults and adults attending sexually transmitted infection clinics

Despite developmental differences between young adults and adults, studies of condom use have not typically considered young adults as a distinct age group. This study sought to examine how condom use and its correlates differed between high-risk young adults and adults. Sexually transmitted infection (STI) clinic patients (n = 763) reported STI history, contraception, negative condom attitudes, fear of partner reaction to condom use and risky behaviours. Past 3-month condom use was examined as unprotected vaginal sex (UVS) acts, proportional condom use and consistent condom use. Regression models tested associations of age group and potential correlates with each condom use outcome. Interaction models tested whether associations differed by age group. Proportional condom use was greater in young adults than adults (mean 0.55 vs. 0.47); UVS and consistent condom use were similar between age groups. Young adults with a recent STI reported less condom use, whereas for older adults, a distant STI was associated with less condom use, compared to others in their age groups. Negative condom attitudes were more strongly linked to UVS acts for younger versus older adults. STI prevention efforts for younger adults may be improved by intensifying counselling about condom use immediately following STI diagnosis and targeting negative condom attitudes.

Arousability as a predictor of sexual risk behaviours in African-American adolescent women

This study examined the impact of sexual excitation (arousability) on sexual risk-taking behaviours in a community sample of African-American adolescent women. A sample of 701 African-American adolescent women completed measures examining their propensity for sexual arousal, impulsivity and sexual behaviour. Compared with women with a lower propensity for sexual arousability, women with a higher propensity reported a greater number of sexual partners, more inconsistent condom use, a greater likelihood of having engaged in sexual intercourse with 'risky' partners, and sex while high on alcohol or drugs. These results indicate that women who have a greater propensity to become sexually aroused in a variety of situations may be at a greater risk for contracting HIV or sexually transmissible infections relative to women with a lower propensity for arousal. This suggests that individual differences in the propensity to become sexually aroused should be considered when developing intervention approaches targeting young African-American women.

A partner-related risk behavior index to identify people at elevated risk for sexually transmitted infections

The purpose of this study was to develop and test a sexual-partner-related risk behavior index to identify high-risk individuals most likely to have a sexually transmitted infection (STI). Patients from five STI and adolescent medical clinics in three US cities were recruited (N = 928; M age = 29.2 years). Data were collected using audio-computer-assisted self-interviewing. Of seven sexual-partner-related variables, those that were significantly associated with the outcomes were combined into a partner-related risk behavior index. The dependent variables were laboratory-confirmed infection with Chlamydia trachomatis, Neisseria gonorrhoeae, and/or Trichomonas vaginalis. Nearly one-fifth of the sample (169/928; 18.4%) tested positive for an STI. Three of the seven items were significantly associated with having one or more STIs: sex with a newly released prisoner, sex with a person known or suspected of having an STI, and sexual concurrency. In combined form, this three-item index was significantly associated with STI prevalence (p < .001). In the presence of three covariates (gender, race, and age), those classified as being at-risk by the index were 1.8 times more likely than those not classified as such to test positive for an STI (p < .001). Among individuals at risk for STIs, a three-item index predicted testing positive for one or more of three STIs. This index could be used to prioritize and guide intensified clinic-based counseling for high-risk patients of STI and other clinics.

Testing pathways linking exposure to community violence and sexual behaviors among African American youth

Exposure to community violence and HIV sexual risks are two major public health concerns among youth. This study tests various pathways linking exposure to community violence and sexual behaviors among African American adolescents. Using a sample of 563 (61% females) African American youth attending high school we examined whether problematic psychological symptoms, low school engagement, and/or negative perceptions of peer norms about safer sex functioned as pathways linking exposure to community violence and sexual behaviors. Major findings indicated that, for boys, the relationship between exposure to community violence and sexual début and sexual risk behaviors were linked by aggression. In addition, the relationship between exposure to community violence and sexual risk behaviors were linked by negative perceptions of peer attitudes about safer sex. For girls, the relationship between exposure to community violence and sexual début was linked by aggression and negative perceptions of peer attitudes about safer sex. These findings provide support for pathways linking exposure to community violence to sexual behaviors.

A Longitudinal Examination of Risk and Protective Factors Associated with Drug Use and Unsafe Sex among Young African American Females

This study prospectively examined associations among multiple theoretically informed risk (e.g., depression, sexual sensation seeking, and risky peers norms) and protective factors (e.g., social support, STI knowledge, and refusal to have sex self efficacy) on unsafe sex among 715 African American adolescent females aged 15-21 who participated in an STI/HIV prevention intervention. Generalized estimating equation models were used to assess associations between baseline characteristics and sexual risk over a 12-month follow up period. Overall risk in this population was high: at baseline, nearly a third of women reported sex under the influence of alcohol or substances; ≥ 2 partners for vaginal sex, and casual sex partners in the 60 days prior to baseline, and nearly 75% of those reporting vaginal sex used condoms inconsistently. In multivariable analysis, when risk and protective factors were simultaneously considered, higher levels of sexual sensation seeking were associated with having multiple sex partners and inconsistent condom use. Greater perception of risky peer norms was associated with a higher risk of having sex under the influence of alcohol or drugs. In addition, higher sex refusal self-efficacy was protective against having multiple; casual; and concurrent sex partners. Incorporating these salient factors into prevention programs may be critical to the development of targeted interventions for this population.

What's age got to do with it? Partner age difference, power, intimate partner violence, and sexual risk in urban adolescents

Adolescent girls with older male main partners are at greater risk for adverse sexual health outcomes than other adolescent girls. One explanation for this finding is that low relationship power occurs with partner age difference. Using a cross-sectional, descriptive design, we investigated the effect of partner age difference between an adolescent girl and her male partner on sexual risk behavior through the mediators of sexual relationship power, and physical intimate partner violence (IPV), and psychological IPV severity. We chose Blanc's framework to guide this study as it depicts the links among demographic, social, economic, relationship, family and community characteristics, and reproductive health outcomes with gender-based relationship power and violence. Urban adolescent girls (N = 155) completed an anonymous computer-assisted self-interview survey to examine partner and relationship factors' effect on consistent condom use. Our sample had an average age of 16.1 years with a mean partner age of 17.8 years. Partners were predominantly African American (75%), non-Hispanic (74%), and low-income (81%); 24% of participants reported consistent condom use in the last 3 months. Descriptive, correlation, and multiple mediation analyses were conducted. Partner age difference was negatively associated with consistent condom use (-.4292, p < .01); however, the indirect effects through three proposed mediators (relationship power, physical IPV, or psychological IPV severity) were not statistically significant. Further studies are needed to explore alternative rationale explaining the relationship between partner age differences and sexual risk factors within adolescent sexual relationships. Nonetheless, for clinicians and researchers, these findings underscore the heightened risk associated with partner age differences and impact of relationship dynamics on sexual risk behavior.

Correlates of consistent condom use among young migrant men who have sex with men (MSM) in Beijing, China

OBJECTIVES

The prevalence of sexually transmitted infections (STIs), including HIV, among men who have sex with men (MSM) has risen in China, mainly due to unprotected sexual intercourse. Migrant MSM might be more vulnerable to the risk of STIs/HIV because of their low socioeconomic status. This study aims at exploring the correlates of consistent condom use among young migrant MSM (aged 18-29 years) in Beijing.

METHODS

Multivariate logistic regression analysis.

RESULTS

The mean age of the sample was 23.7 years. Rural-to-urban migrant MSM accounted for 46% of the sample, and urban-to-urban migrant MSM for 54%. Of 307 migrant MSM, 178 (54%) reported having used a condom every time in the last three sexual episodes with both stable and casual sexual partners. Multivariate logistic regression analysis showed that MSM who had a low monthly income, had often experienced alcohol intoxication, did not use a condom at first sex, and had fewer lifetime male sexual partners were less likely to use condoms consistently.

CONCLUSIONS

Consistent condom use among young migrant MSM was relatively low and was associated with socioeconomic status and alcohol use. Future STIs/HIV prevention programmes should strengthen empowerment, access to condoms, and reduction of alcohol consumption within this socio-economically marginalised group.

Condom use: slippage, breakage, and steps for proper use among adolescents in alternative school settings

BACKGROUND

School-based human immunodeficiency virus (HIV)/sexually transmitted infection (STI), and pregnancy prevention programs often focus on consistent and correct condom use. Research on adolescents' experience using condoms, including condom slippage/breakage, is limited. This exploratory study examines proper condom use and the occurrence of condom slippage/breakage among alternative school youth.

METHODS

Data are from an HIV/STI prevention trial for youth in continuation school settings (N = 776). Analyses included separate hierarchical logistic regression analyses to explore the relationship between potential correlates and each outcome variable.

RESULTS

Students' use of steps for proper condom use varied-73.8% put on the condom before sexual contact, 71.1% squeezed air from the tip, and 92.0% unrolled the condom fully. Notably, 28.5% reported condom slippage/breakage. Results from the regression analyses showed that 4 sets of variables (demographic, substance use, sexual risk behaviors, and condom psychosocial factors) were associated with putting on a condom before sexual contact; none of the variable sets were associated with the other 2 condom steps measured. For slippage/breakage, the demographic and sexual risk behaviors were significant correlates; steps for proper condom use approached statistical significance (p = .058).

CONCLUSIONS

This study extends the limited research on how adolescents use condoms, and highlights important targets for prevention interventions.

Condom Use Trajectories in Adolescence and the Transition to Adulthood: The Role of Mother and Father Support

Few studies have investigated how mother and father support differ on predicting youths' sexual risk behavior. We therefore examined the influence of parental support on condom use trajectories and its correlates in a predominantly African American sample [(N=627; 53% female; M = 14.86 years (SD=. 64)] from adolescence to young adulthood. We used hierarchical growth curve modeling to examine the relationship between condom use, substance use, psychological distress and parental support prospectively. We found that consistent condom use decreased over time and was associated negatively with psychological distress and substance use. Furthermore, both maternal and paternal support were associated with more condom use over time. We discuss the implications of our findings for HIV prevention programs.

Condom effectiveness: where are we now?

After performing a review of prospective cohort evaluations, a focussed assessment of the current knowledge base and methodology pertaining to condom effectiveness against sexually transmissible infections, including HIV, was also conducted. Key observations included the point that studies of condom effectiveness are inherently complex and the potential forms of study bias all generally favour the null hypothesis. Perhaps the most challenging obstacle to rigor in these studies lies in determining which events of condom-protected sex occurred before infection as opposed to after infection when, in fact, infection occurs. This problem leads to misclassification bias; however, other sources of misclassification bias are common. Greater attention to the selection of a recall period, improved precision of self-reported measures, and accounting for condom use errors and problems are critical steps that must occur to promote rigor in these studies. Despite multiple shortcomings, prospective studies of condom effectiveness provide a reasonably favourable evaluation. Subsequent studies, however, should be designed to greatly reduce the error variance that predisposes condom effectiveness studies to type 2 errors that mask the potential value of condoms.

Incentivising safe sex: a randomised trial of conditional cash transfers for HIV and sexually transmitted infection prevention in rural Tanzania

OBJECTIVE

The authors evaluated the use of conditional cash transfers as an HIV and sexually transmitted infection prevention strategy to incentivise safe sex.

DESIGN

An unblinded, individually randomised and controlled trial.

SETTING

10 villages within the Kilombero/Ulanga districts of the Ifakara Health and Demographic Surveillance System in rural south-west Tanzania.

PARTICIPANTS

The authors enrolled 2399 participants, aged 18-30 years, including adult spouses.

INTERVENTIONS

Participants were randomly assigned to either a control arm (n=1124) or one of two intervention arms: low-value conditional cash transfer (eligible for $10 per testing round, n=660) and high-value conditional cash transfer (eligible for $20 per testing round, n=615). The authors tested participants every 4 months over a 12-month period for the presence of common sexually transmitted infections. In the intervention arms, conditional cash transfer payments were tied to negative sexually transmitted infection test results. Anyone testing positive for a sexually transmitted infection was offered free treatment, and all received counselling.

MAIN OUTCOME MEASURES

The primary study end point was combined prevalence of the four sexually transmitted infections, which were tested and reported to subjects every 4 months: Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Mycoplasma genitalium. The authors also tested for HIV, herpes simplex virus 2 and syphilis at baseline and month 12.

RESULTS

At the end of the 12-month period, for the combined prevalence of any of the four sexually transmitted infections, which were tested and reported every 4 months (C trachomatis, N gonorrhoeae, T vaginalis and M genitalium), unadjusted RR for the high-value conditional cash transfer arm compared to controls was 0.80 (95% CI 0.54 to 1.06) and the adjusted RR was 0.73 (95% CI 0.47 to 0.99). Unadjusted RR for the high-value conditional cash transfer arm compared to the low-value conditional cash transfer arm was 0.76 (95% CI 0.49 to 1.03) and the adjusted RR was 0.69 (95% CI 0.45 to 0.92). No harm was reported.

CONCLUSIONS

Conditional cash transfers used to incentivise safer sexual practices are a potentially promising new tool in HIV and sexually transmitted infections prevention. Additional larger study would be useful to clarify the effect size, to calibrate the size of the incentive and to determine whether the intervention can be delivered cost effectively.

Predictors of condom errors among sex workers in Armenia

This cross-sectional study identified the prevalence and correlates of condom-use errors among female sex workers (FSWs) in Armenia. One hundred and seventeen street-based FSWs aged 20-52 years completed an interviewer-administered questionnaire. Condom-use errors were reported by 78.0% of participants. Number of clients, higher frequency of condom application on clients by FSWs, greater perceived barriers to condom use, elevated depressive symptomatology and having sex while drinking alcohol were significantly associated with higher number of condom-use errors. History of sexually transmitted infections (STIs) was marginally significant while consistent condom use was not significant in the final model. The multiple regression model accounted for 32.5% of the variance in condom-use errors. Condom-use errors are prevalent in this population, thus attenuating the intended protective effects of condoms. Interventions with FSWs in Armenia should specifically address the factors identified in this study toward the goal of reducing condom errors and ultimately preventing acquisition of STIs including HIV.

Adherence to dual-method contraceptive use

BACKGROUND

Patient characteristics associated with adherence to dual-method contraceptive use are not known.

STUDY DESIGN

Project PROTECT was a 24-month-long randomized trial designed to promote the use of dual methods of contraception using an individualized computer-based intervention or enhanced standard care counseling intervention. We analyzed 463 women with follow-up data and examined sustained dual-method use (reported at 2+ interviews).

RESULTS

While 32% initiated dual-method contraceptive use, only 9% reported sustained use. Education increased (RR(adj)=4.42; 95% confidence interval [CI] 1.19-16.42), substance abuse decreased (adjusted relative risk [RR(adj)]=0.49; 95% CI 0.24-0.97), no contraceptive use at baseline decreased (RR(adj)=0.32; 95% CI 0.11-0.92) and contraceptive stage of change increased (RR(adj)=5.04; 95% CI 1.09-23.4) adherence to dual-method use.

CONCLUSION

To effectively prevent sexually transmitted diseases and unplanned pregnancies, dual-method use must be consistent and sustained. Future interventions to promote dual-method use should focus on high-risk groups and additional dual-method combinations (e.g., barrier plus intrauterine devices or implants).

Chlamydia trachomatis Infection in minority adolescent women: a public health challenge

Chlamydia trachomatis is the most common bacterial sexually transmitted infection in the United States. This disease disproportionately affects adolescent minority women, and untreated infection can lead to lasting reproductive tract morbidity. Recommendations for primary prevention include patient counseling to decrease risky behavior and increase barrier protection use; secondary prevention recommendations include screening and treatment of affected individuals and their sexual partners, barrier contraception use, as well as counseling to decrease behaviors that lead to reinfection. Despite these strategies, both incidence and prevalence of Chlamydia have continued to escalate in this population. Interventions to decrease chlamydial infection should encompass all facets of primary and secondary prevention as well as address the fundamental barrier to prevention-lack of perception of risk in this young age group.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians.

LEARNING OBJECTIVES

After completion of this educational activity, the obstetrician/gynecologist should be better able to identify current screening guidelines to test for chlamydial infection in sexually active adolescents; obtain more thorough sexual histories, and understand dynamics of disproportionate disease burden in minority teens; recognize and act to decrease the high risk of reinfection in this patient population; and employ novel methods to increase STI screening.

Parenting and adolescent problem behaviors: a comparative study of sons and daughters in Thailand

OBJECTIVE

Investigates parenting practices and the reported sexual and delinquent behaviors among Thai adolescents, by focusing on the difference between sons and daughters.

MATERIAL AND METHOD

Data were derived from 420 families whose adolescents aged 13-14 were randomly selected from seven districts in Bangkok using the probability proportional to size (PPS) method. Interviews were conducted with one parent and one adolescent.

RESULTS

Female adolescents reported higher levels of parental monitoring, parental rules, communication about sex, and parental disapproval of sex, as compared to males. There were no gender differences in the reported sexual and delinquent behaviors among the adolescents. For males, high levels of parental monitoring, greater perception of parent disapproval of sex, and being raised by authoritative parents were associated with less delinquent behaviors. Among females, parental monitoring and parental closeness served as protective factors against sexual and delinquent behaviors.

CONCLUSION

The findings from the present study point to the importance of promoting family institution and parents' childrearing. These findings should be useful for developing a body of knowledge and understanding on adolescent rearing among Thai parents.

Misclassification bias: diversity in conceptualisations about having 'had sex'

Background: Understanding the signification of the word ‘sex’ has implications for both medical research and clinical practice. Little is known about how people of varying ages define sex and how situational qualifiers influence definitions across age groups. To our knowledge, this is the first study of a representative sample to assess attitudes about which sexual behaviours constitute having ‘had sex’ and to examine possible mediating factors (gender, age, giving/receiving stimulation, male ejaculation, female orgasm, condom use or brevity). Methods: A telephone survey of English-speaking residents of Indiana (USA) using random-digit-dialling produced a final sample of 204 men and 282 women (n = 486) ranging in age from 18 to 96 years. Questions assessed the respondents’ attitudes on manual-genital (MG), oral-genital (OG), penile-vaginal intercourse (PVI) and penile-anal intercourse (PAI) behaviours. Results: There was no universal consensus on which behaviours constituted having ‘had sex’. More than 90% responded ‘yes’ to PVI but one in five responded ‘no’ to PAI, three in 10 responded ‘no’ to OG and about half endorsed MG. Fewer endorsed PVI with no male ejaculation (89.1%) compared with PVI without a qualifier (94.8%, P < 0.001). MG was endorsed more often when received (48.1%) than given (44.9%, P < 0.001). Among men, the oldest and youngest age groups were significantly less likely to believe certain behaviours constituted having ‘had sex’. Conclusions: These findings highlight the need to use behaviour-specific terminology in sexual history taking, sex research, sexual health promotion and sex education. Researchers, educators and medical practitioners should exercise caution and not assume that their own definitions of having ‘had sex’ are shared by their research participants or patients.

Truths and myths that influence the sexual decision-making process among young multiethnic college women

In the United States, half of all new human immunodeficiency virus (HIV) cases are among 13- to 24-year-old women. Heterosexual contact is the primary route of transmission (73%). Young African Americans account for 56% of reported HIV cases. In an earlier study, S. T. Roberts and B. L. Kennedy (2006) studied sexual decision making among 100 young multiethnic college women (YMCW). Participants reported high condom use intention (84%) but inconsistent condom use (64%). Participants perceived their risk of acquiring HIV and sexually transmitted diseases (STDs) as low; however, their actual risk was assessed as high. YMCW reported that alcohol and drugs impaired their judgment to practice safer sex. The YMCW concurrently reported that alcohol and drugs were a routine part of their sexual experiences. The current study examined a group of YMCW to elucidate the reasons that the knowledge of safer-sex practices was not put into practice. The authors sought insight into the lived experiences of YMCW's sexual behavioral choices. The qualitative study recruited 15 participants. Focus groups were conducted, and quantitative HIV and STD knowledge questionnaires were administered. The YMCW verbalized high knowledge of HIV, STDs, and safer-sex practices. The questionnaire scores evidenced significant knowledge deficit in these same categories. Themes emerged from the narrative date. Two beliefs or myths explained why women engaged in sex without a condom. The first belief was that YMCW were not in control of their sexual behavior when "being in the moment." The second belief was "not remembering what happened" secondary to alcohol use. The women reported that the myths were culturally accepted in their peer group; however, the YMCW knew that the myths were untrue. The YMCW expressed a strong desire for someone to teach them "real information" on sexuality as this information was missing in their health education courses.

Relationships, love and sexuality: what the Filipino teens think and feel

BACKGROUND

In order to achieve a change among teens' sexual behavior, an important step is to improve our knowledge about their opinions concerning relationships, love and sexuality.

METHODS

A questionnaire including topics on relationships, love and sexuality was distributed to a target population of 4,000 Filipino students from third year high school to third year college. Participants were obtained through multi-stage sampling of clusters of universities and schools. This paper concentrates on teens aged 13 to 18.

RESULTS

Students reported that they obtained information about love and sexuality mainly from friends. However, they valued parents' opinion more than friends'. They revealed few conversations with their parents on these topics. A majority of them would like to have more information, mainly about emotion-related topics. Almost half of respondents were not aware that condoms are not 100% effective in preventing STIs or pregnancies. More girls, compared to boys, were sensitive and opposed to several types of sexism. After adjusting for sex, age and institution, the belief of 100% condom effectiveness and the approval of pornography and sexism were associated with being sexually experienced.

CONCLUSION

There is room for further encouraging parents to talk more with their children about sexuality, specially aspects related to feelings and emotions in order to help them make better sexual choices. Indeed, teens wish to better communicate with their parents on these issues. Condoms are regarded as safer than what they really are by almost half of the participants of this study, and such incorrect knowledge seems to be associated with sexual initiation.

The effect of adolescent virginity status on psychological well-being

Although previous research has found that sexually active teens are more likely to suffer from depression, it is not clear whether this association is causal or spurious in nature. This study uses data from the National Longitudinal Study of Adolescent Health to examine whether virginity status affects self-esteem and depression. For males, fixed effects and instrumental variables (IV) estimates provide little evidence that sex is causally related to psychological well-being. In contrast, IV estimates indicate that sexually active female adolescents are at increased risk of exhibiting the symptoms of depression relative to their counterparts who are not sexually active. Comparing the psychological well-being of females who used contraception at last intercourse with that of virgins suggests that these effects may be ameliorated, but not eliminated, by contraceptive use.

A theory-based approach to understanding condom errors and problems reported by men attending an STI clinic

We employed the information-motivation-behavioral skills (IMB) model to guide an investigation of correlates for correct condom use among 278 adult (18-35 years old) male clients attending a sexually transmitted infection (STI) clinic. An anonymous questionnaire aided by a CD-recording of the questions was administered. Linear Structural Relations Program was used to conduct path analyses of the hypothesized IMB model. Parameter estimates showed that while information did not directly affect behavioral skills, it did have a direct (negative) effect on condom use errors. Motivation had a significant direct (positive) effect on behavioral skills and a significant indirect (positive) effect on condom use errors through behavioral skills. Behavioral skills had a direct (negative) effect on condom use errors. Among men attending a public STI clinic, these findings suggest brief, clinic-based, safer sex programs for men who have sex with women should incorporate activities to convey correct condom use information, instill motivation to use condoms correctly, and directly enhance men's behavioral skills for correct use of condoms.

Consistent condom use in South African youth's most recent sexual relationships

Sexually active South African youth are at high risk for HIV infection but a low prevalence of condom use has been reported in this population. We examined correlates of consistent condom use with most recent sex partners among a nationally representative sample of youth 15-24 years old who reported having had sex in the previous 12 months (N = 6,649). Among men and women, having talked to a partner about using condoms was the most significant predictor of consistent condom use. However, youth who reported being in their most recent relationship for more than 1 year and who reported having had sex one or more times in the last month were more likely to report inconsistent condom use. HIV interventions should empower youth to talk about using condoms with their partners, encourage periodic testing for HIV, and reinforce condom use according to HIV status in long-term relationships.

Slips, breaks and ‘falls’: condom errors and problems reported by men attending an STD clinic

Summary

The objective was to comprehensively assess the prevalence of condom-use errors and problems among male clients attending a public sexually transmitted disease (STD) clinic. Men ( n = 278) attending an STD clinic completed an anonymous questionnaire. Seven errors and six problems were assessed. Summative scores were tested for associations with three key variables. Of 834 condom-protected events: 19% were associated with ‘fit and feel’ problems, 15% involved breakage, 14% involved lost erection, 9% were associated with lost erection while applying condoms, 8% involved slippage during withdrawal and 7% involved slippage during sex. A mean of 6.4 errors/problems were observed. None of these summative variables (total errors, total problems or total of errors and problems) were significantly associated with age, minority status or whether men indicated they had ever been taught how to use condoms. Multiple types of condom-use errors and problems may be highly prevalent among high-risk men attending public STD clinics.

Personal, relational, and peer-level risk factors for laboratory confirmed STD prevalence among low-income African American adolescent females

OBJECTIVES

To identify risk factors for laboratory confirmed sexually transmitted disease (STD) prevalence among low-income African American adolescent females living in a high-risk urban area of the Southern United States.

METHODS

Participants were 715 African American adolescent females recruited from urban clinics. Data collection occurred from 2002 to 2004 and included an audio-computer assisted self-interview lasting about 60 minutes and a self-collected vaginal swab for NAAT to detect Trichomonas vaginalis, Chlamydia trachomatis, and Neisseria gonorrhoeae. Ten personal-level risk factors were assessed as well as 8 risk factors involving either peer or relational factors.

RESULTS

Adolescents (28.8%) tested positive for at least 1 STD. Six personal-level and 4 social-level measures achieved a bivariate screening level of significance. In the multivariate model, only 3 measures achieved significance: gang involvement, social support from peers, and fear of condom use negotiation. Compared to those who had never belonged to a gang, those who had were about 4.2 times more likely (95% CI = 2.16-9.44) to test positive. Adolescents' who had higher levels of fear pertaining to condom use negotiation were more likely to test positive as were adolescents who perceived higher levels of social support from their peers.

CONCLUSIONS

This finding suggests and supports the utility of designing interventions for high-risk African American adolescent females that incorporate objectives to modify the significant social influences related to STD acquisition.

Condoms for sexually transmissible infection prevention: politics versus science

The present review assesses the protection that condoms offer against sexually transmissible infections (STI) and the impact that social, political and religious opinion in the USA has had in the past 8 years on promoting condoms for safer sex. Condoms offer protection against most STI. However, the degree of protection depends on correct and consistent use, the type of sexual activity and the biological characteristics of different infections. Cross-sectional and case-control studies and other observational data provide the majority of evidence for STI prevention. Condoms provide a high level of protection against those infections that are transmitted mainly via infected secretions, including HIV, gonorrhoea, chlamydia and trichomoniasis. Protection against those infections transmitted via skin and mucous membrane contact, including Herpes simplex virus infection and human papilloma virus, appears to be less. The Bush administration, driven by conservative political, social and religious elements in the USA, has mounted a concerted campaign to undermine the role of the condom in health-promotion activities in the USA and overseas by undervaluing and misrepresenting scientific data, and through a sustained and well-funded promotion of abstinence-only education. However, this has lead to considerable controversy and disillusionment with abstinence-only education, both at home and abroad, and there is now incontrovertible evidence that abstinence-only programs are ineffectual.

Correlates of Putting Condoms On After Sex Has Begun and of Removing Them Before Sex Ends: A Study of Men Attending an Urban Public STD Clinic

This study aimed to identify possible correlates of putting condoms on after sex has begun and taking them off before sex has ended among male patients of an urban, public sexually transmitted disease clinic. Participants responded to a questionnaire and were largely African American men, 18 to 35 years old, who had used a condom during penile-vaginal intercourse at least three times in the past 3 months. In controlled analyses, men who were not highly motivated to use condoms correctly were nearly twice as likely to put a condom on after sex had begun. Men who reported erection loss during sex were about twice as likely to remove condoms before sex ended. Men reporting difficulties with the fit and feel of condoms were 2.5 times more likely to remove condoms early. Identified correlates may be amenable to clinic-based education and counseling augmented by offering a variety of condom brands and sizes to patients.

A quantitative study on the condom-use behaviors of eighteen- to twenty-four-year-old urban African American males

This research study sought to develop, pilot test, and assess a brief male-centered condom promotion program for urban young adult African American males. For study implementation, both qualitative and quantitative research methods were used, and the project was guided by tenets of two common but integrated theoretical frameworks in HIV/sexually transmitted disease (STD) prevention research: the social cognitive theory and the stages of change model. The purpose of the qualitative component was to identify and explore condom-use barriers and facilitators while that of the quantitative component was to identify the prevalence of condom-related behaviors and the feasibility of program administration. After recruitment of study participants from hang-out spots and street intercepts, study participants were self-administered a baseline survey regarding their perceived condom-use behaviors prior to random assignment to program conditions (a condom promotion program and an attention-matched comparison condition). In this paper, we report the findings from the analyses of the quantitative baseline survey data. While the occurrence of HIV/STD-related risk behavIors were highly prevalent among this population; importantly, regression analyses revealed that sexual debut, favorable attitudes toward condom use, social or personal connectedness to HIV/STDs, health beliefs, perceived susceptibility, unprotected sexual encounters, and refusal skills were predictive of retrospective (i.e., prior 30 days) condom use while positive reasons (pros) to use condoms, condom-use beliefs, condom-carrying, health belief, unprotected sexual encounters and refusal skills were also predictive of prospective (i.e., future 30 days) condom-use intentions. The implications and limitations of this study are described and recommendations provided for program development.

A Decision Rule to Identify Adolescent Females with Cervical Infections

OBJECTIVE

To develop a clinical decision rule to direct empiric treatment of adolescent females with Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) (or both) cervical infections in a pediatric emergency department.

METHODS

This was a cross-sectional study of adolescent females with symptoms necessitating sexually transmitted infection (STI) testing. The outcome was defined as cervical specimens positive for either GC on culture or CT on nucleic amplification assay test. Clinical variables included demographic, historical, physical, and laboratory findings. Bivariate associations were assessed using chi-square for categorical data and Student's t test for continuous variables. Variables significant at p < 0.5 were eligible for logistic regression (LR). Recursive partitioning (RP) analysis was used to create a clinical decision rule.

RESULTS

Of the 250 subjects, 83 (33.2%) were positive for GC/CT. The adjusted odds ratios (aOR) and 95% confidence intervals (CI) of the LR model were African American race (aOR = 3.2, CI 1.3-7.9), new partner within 3 months (aOR = 1.9, CI 1.0-3.5), cervical discharge (aOR = 2.0, CI 1.1-3.7), absence of yeast forms (aOR = 3.3, CI 1.3-10), and >10 white blood cells (WBCs) (aOR = 2.5, CI 1.3-4.6) on vaginal gram stain. Variables comprising the RP analysis included partner penile discharge, >10 WBCs on vaginal gram stain, African American race, absence of yeast forms on vaginal gram stain, and no hormonal birth control use. This algorithm was 75% sensitive and 71% specific, with a negative predictive value of 85%.

CONCLUSIONS

The LR model confirmed associations seen in other populations. Although STI testing is imperative, the RP model can be used to direct empiric treatment among high-risk adolescent females.

Condom use with steady and casual partners in inner city African-American communities

OBJECTIVES

This study examined rates of and factors associated with consistent condom use with steady partner and with casual partners in inner city African-American communities with high sexually transmitted infection (STI) prevalence.

METHODS

Structured interviews were conducted using street intercept methods and venue based sampling with 997 African-American residents of inner city neighbourhoods in Houston and Dallas, Texas; of which data were analysed for the 736 that reported having sex in past 2 months. Condom use was measured as a proportion of use in last five sex acts with steady and casual partners.

RESULTS

Reported rates of consistent condom use were high-31.4% with steady partner and 29.5% with casual partner. Multivariate logistic models differed by type of partner. Married people and those with history of STI were less likely to use condoms with the main partner, while older people were less likely and males, and those visiting a doctor more likely to use condoms with casual partners.

CONCLUSIONS

The proportion of condom use with both partner types was relatively high reflecting a general trend towards increased condom use in the United States. The finding of lower reported rates with casual partners has been discussed. Factors associated with condom use differ according to type of partner. Precise measurement of actual condom use continues to be an elusive task but is required for the design of appropriate messages and evaluation of STI programmes.

Reducing African-American women's sexual risk: can churches play a role?

PURPOSE

This study investigates: 1) perceptions of clergy regarding their current counseling and the need for future programs concerning sexual risk-taking, 2) sexual risk behaviors among a group of African-American women, 3) women's attitudes regarding condom use, and 4) women's receptiveness to church programs regarding sexual risks.

METHODS

The clergy of 50 randomly selected predominantly African-American churches in five North Carolina counties were contacted regarding participation. Female parishioners ages 18-30 from participating churches were invited to complete written surveys concerning women's health.

RESULTS

Of 50 clergy repeatedly contacted, 38 declined to participate and eight did not complete the interview. Only four interviews could be completed. Counseling regarding sexual risk was not common among the four clergy. They often advised parishioners to practice abstinence. Survey data was received from 142 respondents at 14 churches. Nearly 84% of the women surveyed had a history of sexually transmitted diseases (STDs). Almost all of the respondents were receptive to a church program regarding sexual risks.

CONCLUSIONS

Despite the sexual risks among African-American women, in this study, many clergy were unwilling to address prevention and were uncomfortable discussing issues related to sexual health. However, the few clergy who agreed to participate were very receptive to future programs.

Why are young college women not using condoms? Their perceived risk, drug use, and developmental vulnerability may provide important clues to sexual risk

BACKGROUND

Young multiethnic college women (YMCW) are at risk for STDs and HIV secondary to high-risk sexual behaviors that are related to developmental issues such as invincibility, low perceived risk, and substance use.

METHOD

One hundred YMCW on a southern California university campus completed surveys that examined variables that impacted their sexual risk.

RESULTS

The study yielded many significantly correlated variables. Women with low perceived risk, lower use of drugs and alcohol, and who had parental involvement had lower sexual behavior risk. Women that were sexually assertive, had intentions to use condoms, and did not use substances used condoms more often. Older students in advanced grades who had steady partners used substances less and had decreased sexual risk, however, they experienced partner resistance to condoms, which canceled out any reduced risk. In a multiple regression analysis, condom use intention and substance use predicted condom use, perceived risk and substance use predicted sexual behavior risk. White women had significantly higher substance use, perceived sexual risk, and sexual behavior risk than did Latinas and African Americans.

CONCLUSIONS

Despite their assertiveness and intentions, many participants had multiple sexual partners, and 64% of the YMCW were inconsistent condom users. Despite knowing the elevated risks, 52% used drugs and alcohol during sex. Negative attitudes (61%) about condoms were also demonstrated as a key factor in the lack of condom use.

Do sexual health services encourage teenagers to use condoms? A longitudinal study

OBJECTIVE

Sexual health services have the potential to encourage teenagers' condom use through both the free supply of condoms and counselling. This study investigated whether 15/16-year-olds who attended sexual health services used condoms more and had different beliefs about condoms compared to those who did not use these services.

METHODS

First, a cross-sectional multivariate model investigated the association between service visits and condom consistency (a ratio of the number of times a condom was used to the number of times a teenager had sexual intercourse in the past year) in teenagers at age 15/16 years (n = 1013). Second, a longitudinal multivariate model examined links between service use and changes in condom-related cognitions measured at age 13/14 and age 15/16 years (n = 3432).

RESULTS

Visiting a service for free condoms was linked with greater condom consistency, after controlling for attitudes towards condoms, condom purchase and other factors. Visiting a service for other purposes was associated with lower consistency. Obtaining free condoms from services predicted greater condom self-efficacy and personal responsibility, and lower negative feelings relating to sexual pleasure when condoms were used. However, visiting a service for other purposes predicted less positive attitudes towards dual protection.

CONCLUSIONS

Obtaining free condoms from services was associated with greater condom use and positive changes in attitudes towards condoms, although the role of service counselling remains unclear. Services could do more to stress the need for continued dual protection against sexually transmitted infections (STIs) when prescribing the pill.

Correlates of condom failure among adolescent males: an exploratory study

OBJECTIVE

To identify the prevalence and correlates of condom failure (defined as breakage or slipping off in the past 90 days) among a sample of adolescent males (15 to 21 years of age).

DESIGN

A cross-sectional study of 481 condom-using males residing in three US cities (Atlanta, GA, Providence RI, Miami FL). Data were collected, in the years 2000 and 2001, using audio computer-assisted self-interviewing technology. Prevalence ratios were used to determine the strength and significance of bivariate associations between ten assessed correlates and condom failure. Correlates achieving a screening level of significance were entered into a multivariate model that was used to calculate adjusted odds ratios (AOR).

RESULTS

Recent condom failure was reported by 34.1%. Younger adolescents were about one-third less likely to report condom failure (AOR = 0.66; P = 0.4). Adolescents reporting multiple sex partners were about 80% more likely to report failure (AOR = 1.84; P = 0.09). Adolescents indicating they had sex with someone on the same day they met the person were about 80% more likely to report failure (AOR = 1.77; P = 0.02). Finally, adolescents indicating recent problems obtaining condoms were about 70% more likely to report failure (AOR = 1.69; P = 0.1). Failure was not less common among those reporting a history of STD infection or those ever impregnating a partner.

CONCLUSION

Because adolescent males may commonly experience condom failure, targeted clinic- and community-based programs designed to reduce user error could be an important aspect of preventing pregnancy and the spread of STDs.

Condom effectiveness for prevention of Chlamydia trachomatis infection

BACKGROUND/OBJECTIVES

A growing body of evidence is increasingly demonstrating the effectiveness of condoms for sexually transmitted infection (STI) prevention. The purpose of the present analysis was to provide a disease specific estimate for the effectiveness of condoms in preventing Chlamydia trachomatis infection while controlling for known exposure to infection.

METHODS

Condom effectiveness for C trachomatis was estimated using a medical record database from a public sexually transmitted disease clinic (n = 1455). Clients were classified as having known exposure to C trachomatis if they presented to the clinic as a contact to an infected partner.

RESULTS

Among clients with known exposure, 13.3% of consistent condom users were diagnosed with C trachomatis infection compared to 34.4% of inconsistent condom users (adjusted odds ratio = 0.10; 95% CI: 0.01 to 0.83). Among clients with unknown exposure, there was no observed protective effect of condoms.

CONCLUSIONS

This study provides further evidence that condoms are effective in preventing C trachomatis infection by reporting a disease specific estimate and restricting analyses to individuals with known exposure.

Accounting for failures may improve precision: evidence supporting improved validity of self-reported condom use

OBJECTIVES

To determine whether a measure of unprotected vaginal sex that is adjusted for condom failures would produce improved accuracy in predicting biologically confirmed STDs (chlamydia and gonorrhea) among female teens.

METHODS

Self-reported measures were collected using audio-computer-assisted self-interviewing. DNA amplification for the presence of Chlamydia trachomatis and Neisseria gonorrhoeae was conducted.

RESULTS

The unadjusted measure of unprotected vaginal sex was not significantly associated with biologically confirmed prevalence of STDs (prevalence ratio [PR] = 1.51; 95% CI = 0.71-3.21; P = 0.28). Alternatively, the adjusted measure achieved significance (PR = 3.59; 95% CI = 1.13-11.38; P = 0.014). More than one quarter (25.6%) of teens using condoms inconsistently and/or incorrectly tested positive for an STD compared to 7.1% among those reporting the consistent and correct use of condoms.

CONCLUSION

Findings demonstrate that studies of condom effectiveness should use an adjusted measure of condom use to achieve precision and rigor.

Condom failure among adolescents: implications for STD prevention

This study of 921 adolescents found condom failure (past 90 days) was experienced by at least one-third of the sample, regardless of gender. Frequency of condom failure was positively associated with STD diagnosis (AOR = 1.22, 95% CI = 1.01-1.48), with the odds of testing positive increasing 22% for each added event of failure.

Behavioral Interventions—Rationale, Measurement, and Effectiveness

Effective STD and HIV prevention requires synergism of individual-based prevention behaviors and societal/structural supports that will promote and maintain these behaviors. We should also expect the unexpected. STD rates in gay men have risen after effective prevention of HIV/STD in gay men and effective antiretroviral therapy. New drugs of abuse, such as methamphetamine ("crystal meth"), have induced risky sexual behaviors in gay and heterosexual communities. Economic dislocation in Eastern Europe has resulted in trafficking of commercial sex workers to Europe, the Mideast, and Asia, all with the potential for STD and HIV spread. James Curran, formerly director of the HIV epidemiology and prevention effort at the CDC, has written: It is ironic that the two clearest examples of large-scale success in HIV prevention-reduction in HIV transmission in gay men in the United States and national declines in HIV incidence in Thailand-arise in societies/communities known in their own way for sexual openness....the openness in both communities provided the environment to make the powerful revolutionary changes needed. In Africa, the powerful voice of President Museveni of Uganda has also encouraged candor about sexual risk-taking and facilitated that nation's encouraging early success in reducing HIV prevalence...Unfortunately, most of the world remains unable or unwilling to deal frankly and consistently with sexuality despite the considerable risks of HIV infection in many communities. There is a worldwide sexual hangup hampering HIV prevention efforts.
