Men with broken condoms: who and why?

OBJECTIVES: To identify (1) the prevalence of condom breakage, and demographic and sexuality-related differences among young men who have sex with women reporting and not reporting this event; (2) condom-specific behaviours associated with breakage. METHODS: Young men (n = 278) attending a clinic for treatment of sexually transmitted infections (STIs) responded to an anonymous questionnaire aided by a CD recording of the questions. The samples were screened to include only men who had used a condom during penile-vaginal sex at least three times in the past 3 months. Condom-specific behaviours (including breakage) were assessed using these last three acts of condom use as the recall period. Correlates achieving bivariate significance were subjected to multivariate analysis. RESULTS: Nearly one third (31.3%) of the men reported recent breakage. The breakage rate was 15%. Three correlates significantly distinguished between men who did and did not report breakage. Men who had past STIs were more likely to report breakage (adjusted odds ratio (AOR) 2.08), as were men who also reported condom slippage (AOR 2.72). Less self-efficacy for correct condom use was also significantly associated with breakage (AOR 1.07). Further, three condom-specific behaviours were significantly associated with breakage: allowing condoms to contact sharp objects (AOR 2.6), experiencing problems with the "fit or feel" of condoms (AOR 2.3) and not squeezing air from the receptacle tip (AOR 2.0). CONCLUSIONS: Breakage may be common and may occur in a larger context of difficulties with condoms. STI clinics could potentially benefit some men by providing instructions on the correct use of condoms.

Biologically confirmed sexually transmitted infection and depressive symptomatology among African-American female adolescents.

OBJECTIVE: To determine prospectively the relation between sexually transmitted infection (STI) diagnosis and depressive symptomatology. METHODS: Secondary data analyses were performed on 175 sexually active African-American female adolescents, who were recruited from high risk neighbourhoods in Birmingham, Alabama, United States. RESULTS: ANCOVA was used to compare adolescents who tested positive with adolescents who tested negative on three waves of depressive symptom scores, controlling for age. The STI positive group had higher depressive symptom levels at 6 months relative to the STI negative group. This result was moderated by baseline depressive symptom levels: for adolescents above the clinical threshold, the STI negative group experienced a decrease in symptoms at 6 months whereas the STI positive group maintained the same level. For adolescents below the clinical threshold, there were no changes in depressive symptom levels regardless of diagnosis. CONCLUSIONS: Receiving an STI diagnosis may affect depressive symptomatology for those at risk for depression. Screening for depression in settings that provide STI testing and treatment may be warranted for this population.

Prevention and control of sexually transmitted infections among adolescents: the importance of a socio-ecological perspective--a commentary.

The sexually transmitted infection (STI) epidemic among adolescents in the USA is inextricably tied to individual, psychosocial and cultural phenomena. Reconceptualizing the epidemic within an expanded socio-ecological framework may provide an opportunity to better confront its challenges. In this article, we use a socio-ecological framework to identify determinants of adolescents' sexual risk and protective behaviours as well as antecedents of their STI acquisition. The goal is to provide a synthesis of several discrete categories of research. Subsequently, we propose an integrated strategy that addresses the STI epidemic among adolescents by promoting a socio-ecological perspective in both basic research and intervention design. This approach may expand the knowledge base and facilitate the development of a broader array of intervention strategies, such as community-level interventions, policy initiatives, institutionally based programmes, and macro-level societal changes. Although there are inherent challenges associated with such an approach, the end result may have reciprocal and reinforcing effects designed to enhance the adoption and maintenance of STI-preventive practices among adolescents, and further reduce the rate of STIs.

The psychosocial impact of serological herpes simplex type 2 testing in an urban HIV clinic.

BACKGROUND/OBJECTIVES: Herpes simplex virus type 2 (HSV-2) is a common infection among HIV infected people. HSV type specific serologies permit the diagnosis of previously unrecognised HSV-2 infection. While substantial psychosocial morbidity has been associated with a clinical diagnosis of genital herpes, the burden associated with a serological diagnosis of HSV-2 is unclear. This study prospectively measured the psychosocial response to a new serological HSV-2 diagnosis in patients receiving care at an urban HIV clinic. METHODS: At entry, sera were tested for HSV-1 and HSV-2 antibodies by western blot. Participants completed a 90 item psychosocial and life quality questionnaire at enrollment, and at 2 weeks, 3 months, and 6 months after receiving test results. RESULTS: Of 248 HIV infected participants, 172 (69.4%) were HSV-2 seropositive and 116 (67.4%) seropositive people did not have a previous history of genital herpes. After correction for multiple comparisons, no statistically significant differences were detected on the psychosocial and life quality scales between those who received a new HSV-2 serological diagnosis compared with those who were HSV-2 seropositive with a history of genital herpes, or those who tested HSV-2 seronegative. Additionally, no significant changes in scores were observed during follow up. CONCLUSIONS: HSV-2 was a common but often unrecognised infection in this urban HIV clinic and participants coped well with a positive HSV-2 result. Concerns about psychosocial burden should not deter serological testing for HSV-2. Given the epidemiological and clinical interaction between HSV-2 and HIV, these data support routine HSV-2 testing of HIV infected people.

Assessment of condom use in men and women.

Self-reported condom use is a key variable in surveys of sexual behavior and in studies evaluating interventions to reduce the risk of sexually transmitted infections. This article provides a review of how male condom use has been assessed in research. We critically review a number of methodological issues, including the length of the recall period, terminology, specification of partner variables, validity and reliability of condom use, and use of newer data collection methods such as daily diaries and computer-assisted and online technologies. Assessment of condom use errors and problems, and the role of women in condom use are discussed. Finally, we offer recommendations for improving assessment of condom use in future research.

If the condom fits, wear it: a qualitative study of young African-American men.

OBJECTIVE: To extend the current knowledge base pertaining to condom failure among young African-American men by assessing their experiences with male condom use. METHODS: Qualitative assessments were conducted with 19 African-American men (aged 18-29 years) who had just been diagnosed with an STI and reported using condoms in the previous 3 months. RESULTS: Five categories were identified from the data. These categories pertained to: (1) the "fit and feel" of condoms; (2) condom brand and size; (3) application problems; (4) availability of condoms and lubricants; and (5) commitment to condom use. Common themes included reasons why men believed condoms would break or slip off during sex. Comfort problems, including tightly fitting condoms and condoms drying out during intercourse, were mentioned frequently. Condom associated erection problems were often described. Many men also noted that condom use reduced the level of sexual satisfaction for their female partners. Men noted that finding the right kind of condom was not always easy and it became apparent during the interviews that men typically did not acquire lubrication to add to condoms. Despite their expressed problems with using condoms, men were, none the less, typically emphatic that condom use is an important part of their protective behaviour against STIs. CONCLUSION: Men were highly motivated to use condoms; however, they experienced a broad range of problems with condom use. With the exception of losing the sensation of skin to skin contact, the vast majority of these problems may be amenable to behavioural interventions.

Social capital, poverty, and income inequality as predictors of gonorrhoea, syphilis, chlamydia and AIDS case rates in the United States.

BACKGROUND: Social capital has been related to a number of important public health variables such as child welfare, mortality, and health status. However, the relation of social capital to infectious diseases has received relatively little attention. The relation of social capital to health measures is often posited to be related to the key societal variables of poverty and income inequality. Therefore, any exploration of the correlation between social capital and infectious diseases should also include examination of the association with poverty and income inequality. OBJECTIVE: This study examined the state level association between social capital, poverty, income inequality, and four infectious diseases that have important public health implications given their long term sequelae: gonorrhoea, syphilis, chlamydia, and AIDS. METHOD: A state level, correlational analysis (including bivariate linear correlational analysis, and multivariate linear stepwise regression analysis) was carried out. 1999 state level rates of gonorrhoea, syphilis, chlamydia, and AIDS were the main outcome measures. RESULTS: In bivariate analyses, poverty was significantly correlated with chlamydia; income inequality was significantly correlated with chlamydia and AIDS case rates; and social capital was significantly correlated with all outcome measures. In stepwise multiple regression analyses, social capital was always the strongest predictor variable. CONCLUSIONS: These results suggest that social capital is highly predictive of at least some infectious diseases. The results indicate the need for further research into this relation, and suggest the potential need for structural interventions designed to increase social capital in communities.

Enhancing STD/HIV prevention among adolescents: the importance of parenteral monitoring.

The risk of acquiring sexually transmitted diseases (STDs) and HIV infection is one of the most significant and immediate risks to the health and well being of adolescents. One promising strategy to protect adolescents from STD/HIV infection is to promote parental monitoring. In this article, we first review selected observational studies that provide evidence supporting the value of parental monitoring in reducing adolescents' risk of STD/HIV acquisition. Subsequently, we discuss the potential implications of the research in regards to clinic- and community-based STD/HIV prevention programs for adolescents.

HIV/STD-protective benefits of living with mothers in perceived supportive families: a study of high-risk African American female teens.

BACKGROUND: The joint influence of living with the mother in a perceived supportive family may be an important HIV/STD-protective factor among sexually active female adolescents. METHODS: Sexually active African American female adolescents (N = 522) completed a self-administered survey and structured interview. Adolescents scoring high on family support and reporting that their mother lived with them were compared with the remaining adolescents in respect to unprotected vaginal sex (past 30 days), sex with a non-steady partner (past 6 months), communication with sex partners, attitudes toward condoms, and perceived ability to negotiate condom use. Logistic regression analyses controlled for the influence of parent-adolescent communication about sex and parental monitoring. RESULTS: Adolescents residing with their mothers in a perceived supportive family were more likely to communicate with their sex partners about sexual risk (OR = 1.53). They were less likely to report sex with a non-steady partner (OR = 0.51) or having unprotected sex with a steady partner (OR = 0.52) or any partner (OR = 0.55). CONCLUSIONS: Controlled analyses suggest that living with the mother in a perceived supportive family is an important HIV/STD-protective factor among female adolescents. HIV/STD prevention programs for female adolescents that include the mothers may promote positive and lasting effects.

Correlates of using dual methods for sexually transmitted diseases and pregnancy prevention among high-risk African-American female teens.

PURPOSE: To identify correlates of consistent dual-method use among African-American female adolescents at risk of sexually transmitted diseases (STDs) and pregnancy. METHODS: A convenience sample of 522 sexually active female teens attending adolescent medicine clinics, health department clinics, and school health classes volunteered. Recruitment sites were in low-income neighborhoods of Birmingham, Alabama. Adolescents completed a questionnaire and a face-to-face interview and provided vaginal swab specimens for laboratory diagnosis of STDs. Those reporting use of condoms and at least one other method of contraception, for each of the last five occasions they had sex were classified as consistent dual-method users. The questionnaire assessed frequency of adolescents' communication with their parents and partners about sex. The questionnaire also assessed two measures of parental supervision and adolescents' desire to avoid pregnancy. Multiple logistic regression assessed the independent contribution of each correlate of consistent dual-method use. RESULTS: Seventy-one adolescents (13.6%) were classified as consistent dual-method users. A strong desire to avoid pregnancy was the most influential correlate of consistent dual-method use [odds ratio (OR) =2.3]. Adolescents reporting that their parents generally knew whom they were with (OR = 2.0) and those reporting more frequent communication with parents (OR = 1.9) were also more likely to be consistent dual users. CONCLUSION: The findings suggest the need for research to examine the efficacy of interventions building on adolescent females' desire to avoid pregnancy. Study findings also suggest that interventions promoting improved parent-adolescent communication and improved parental supervision may contribute to adolescents' use of dual methods for STD and pregnancy prevention.

Perceived versus actual knowledge about correct condom use among U.S. adolescents: results from a national study.

PURPOSE: To assess the prevalence of three misconceptions about correct condom use and determine whether prevalence of these misconceptions varied by gender, sexual intercourse experience, experience using condoms, and the relationship between adolescents' actual and perceived knowledge about correct condom use. Variables that predicted misconceptions about correct condom use were also identified. METHODS: Data from the National Longitudinal Study of Adolescent Health were analyzed to determine prevalence of misconceptions among 16,677 adolescents. Misconceptions were: (a) no space at the tip of the condom, (b) Vaseline can be used with condoms, and (c) lambskin protects against the acquired immunodeficiency virus better than latex. Chi-square analyses determined differences in prevalence of misconceptions between male and female adolescents based on their sexual and condom use experience as well as their level of perceived knowledge about correct condom use. Logistic regression models identified predictors of reporting misconceptions. RESULTS: Depending on intercourse experience and experience using condoms, about one-third to one-half believed the first two misconceptions and about one-fifth believed the latter one. Perception of knowledge about correct condom use was infrequently related to actual knowledge. Misconceptions were less likely among older adolescents, those ever having intercourse, those reporting four or more lifetime intercourse partners, those who had used condoms, females, and those not reporting a religious affiliation. CONCLUSIONS: Misconceptions about correct condom use are common among adolescents. Sexually active adolescents need more complete information about correct condom use.

Correlates of adolescent females' worry about undesired pregnancy. the importance of partner desire for pregnancy.

STUDY OBJECTIVE: The purpose of this study was to determine correlates of worry about pregnancy among a high-risk sample of low-income African-American adolescent females. Specifically, we tested the hypothesis that perceived male partner desire for pregnancy and level of sexual communication would be independently associated with adolescent females' worry about becoming pregnant. DESIGN: A survey of sexually active African-American adolescent females, 14-18 years of age. SETTING: Recruitment was conducted in low-income neighborhoods of Birmingham, Alabama, characterized by high rates of unemployment, substance abuse, violence, and teen pregnancy. PARTICIPANTS: Adolescents (N = 522) completed a survey and a face-to-face interview, and provided a urine specimen for pregnancy testing. MAIN OUTCOME MEASURE: Nonpregnant adolescents reporting steady relationships with a male sex partner (over the past 6 months) and indicating no immediate desire to become pregnant were included in the analysis (n = 196). Two questionnaire items assessed level of worry about becoming pregnant. RESULTS: Compared to adolescent females reporting their partner did not desire pregnancy, those perceiving their partner desired pregnancy were nearly three times more likely to experience high worry about becoming pregnant (AOR = 2.85; P =.009). Engaging in sex unprotected by a condom was an equally important correlate of high worry (AOR = 2.84; P =.013). Level of communication between partners about pregnancy prevention was not significant. CONCLUSIONS: Adolescent females may experience high worry about becoming pregnant due to desires of their male partner as well as their recent sexual risk behavior.

Validity of self-reported sexually transmitted diseases among African American female adolescents participating in an HIV/STD prevention intervention trial.

BACKGROUND: Studies assessing the validity attributed to self-reported measures of sexually transmitted diseases (STDs) clearly are needed, particularly those used for high-risk populations such as female adolescents, in whom STD prevention is a priority. GOAL: To determine the accuracy of self-reported STD test results in female adolescents over a relatively brief period ( approximately 28 days). STUDY DESIGN: A prospective, randomized, controlled clinical trial of STD/HIV prevention for African American females, ages 14 to 18, was conducted. Study participants were recruited from medical clinics and school health classes in low-income neighborhoods of Birmingham, Alabama, that had high rates of unemployment, substance abuse, violence, STDs, and teenage pregnancy. RESULTS: Of the 522 adolescents enrolled in the trial, 92% (n = 479) completed baseline STD testing and follow-up surveys. At baseline, 28% had positive test results for at least one disease: 4.8% for Neisseria gonorrhoeae, 17.1% for Chlamydia trachomatis, and 12.3% for Trichomonas vaginalis. Of the adolescents with negative STD test results, 98.8% were accurate in their self-report of STD status, as compared with 68.7% of the adolescents with positive results. Underreporting varied by type of STD. Adolescents who accurately reported their positive STD status were significantly more likely to report their receipt of treatment accurately (P < 0.001). CONCLUSIONS: The substantial underreporting of STD incidence in this study suggests that reliance on self-reports of STD history may introduce misclassification bias, potentially leading to false conclusions regarding the efficacy of prevention interventions. This observation highlights the importance of using biologic indicators as outcome measures.

A prospective study of psychological distress and sexual risk behavior among black adolescent females.

OBJECTIVE: The purpose of the study was to examine the association between adolescents' psychological distress and their sexually transmitted disease/human immunodeficiency virus (STD/HIV)-associated sexual behaviors and attitudes. METHOD: Sexually active black adolescent females (N = 522) completed, at baseline and again 6 months later, a self-administered questionnaire that assessed sexual health attitudes and emotional distress symptoms (using standardized measures, alpha =.84), a structured interview that assessed STD/HIV-associated sexual risk behaviors, and a urine screen for pregnancy. RESULTS: In multivariate analyses, controlling for observed covariates, adolescents with significant distress at baseline were more likely than their peers, after 6 months, to be pregnant (adjusted odds ratio [AOR]: = 2.0), have had unprotected vaginal sex (AOR = 2.1), have nonmonogamous sex partners (AOR = 1.7), and not use any form of contraception (AOR = 1.5). Additionally, they were also more likely to: perceive barriers to condom use (AOR = 2.2), be fearful of the adverse consequences of negotiating condom use (AOR = 2.0), perceive less control in their relationship (AOR = 2.0), have experienced dating violence (AOR = 2.4), feel less efficacious in negotiating condom use with a new sex partner (AOR = 1.6), and have norms nonsupportive of a healthy sexual relationship (AOR = 1.7). DISCUSSION: The findings suggest that psychological distress is predictive over a 6-month period of a spectrum of STD/HIV-associated sexual behaviors and high-risk attitudes. Brief screening to detect distress or depressive symptoms among adolescent females can alert the clinician to the need to conduct a sexual health history, initiate STD/HIV-preventive counseling, and refer for comprehensive psychological assessment and appropriate treatment. Among adolescents receiving STD treatment, those with even moderate emotional distress may be at heightened risk for further unhealthy outcomes. STD/HIV interventions should also consider psychological distress as one potential risk factor that may impact program efficacy.

Correlates of unprotected vaginal sex among African American female adolescents: importance of relationship dynamics.

OBJECTIVE: To determine the associations between the frequency of unprotected vaginal sex (UVS) and female adolescents' perceptions, particularly their perceptions of relationship dynamics. DESIGN: Cross-sectional study of 522 African American female adolescents enrolled in a sexually transmitted disease (STD) and human immunodeficiency virus prevention intervention trial. SETTING AND PARTICIPANTS: A volunteer sample of adolescents recruited from neighborhoods characterized by high rates of unemployment, substance abuse, violence, and STDs; 28% tested positive for STDs as assessed by DNA amplification or culture. MAIN OUTCOME MEASURE: Frequency of UVS assessed by interview using a 6-month recall period. RESULTS: Among adolescents having steady relationships, those spending more time with their boyfriends and having longer relationships reported a significantly greater frequency of UVS. Other significant correlates included perception of more girlfriends using condoms, no history of STDs, stronger normative beliefs favoring male decision making in relationships, greater pregnancy worry, and greater perceived invulnerability to STDs. For adolescents reporting casual relationships, personal barriers to condom use, no history of STDs, and reporting that their boyfriends typically decide when to have sex were associated with more frequent UVS. CONCLUSIONS: Adolescents' perceptions, particularly their perceptions of relationship dynamics, played an integral role in explaining female adolescents' frequency of UVS with both steady and casual partners. Female adolescents in steady relationships differ from those in casual relationships relative to their prevention needs. These findings have implications for clinic- or community-based STD and human immunodeficiency virus prevention programs.
