Efficacy of an HIV prevention program among female adolescents experiencing gender-based violence.

OBJECTIVES: We examined the efficacy of an HIV prevention intervention among African American female adolescents reporting a history of gender-based violence. METHODS: In this analysis of a subgroup of participants involved in a randomized controlled trial, consistent condom use, psychosocial mediators associated with HIV-preventive behaviors, and presence of sexually transmitted diseases were assessed at 6- and 12-month follow-ups. The intervention emphasized ethnic and gender pride, HIV knowledge, condom attitudes, healthy relationships, communication, and condom use skills. RESULTS: Relative to the comparison condition, participants randomized to the intervention reported using condoms more consistently, had fewer episodes of unprotected vaginal sex, engaged in a greater proportion of protected intercourse acts, were more likely to have used a condom during their most recent intercourse, were less likely to have a new sexual partner, were less likely to have a sexually transmitted disease, and demonstrated more proficient condom skills. CONCLUSIONS: Given the substantial prevalence of gender-based violence among female adolescents and the associations observed between gender-based violence, HIV risk, and HIV infection, it is essential that HIV interventions involving young women address partner violence.

Implementation of a family intervention to increase fruit and vegetable intake: the Hi5+ experience.

Family is an important, yet challenging, target for dietary intervention. This article describes the implementation of Hi5+, a family fruit and vegetable (FV) promotion program. Complementing a fourth-grade school curriculum, the seven weekly Family Fun Nites were at-home family meal sharing and game evenings. A sample of families (N = 575; 69% consented) from schools in a southeastern U.S. urban area received tailored intervention materials based on their FV attitudes and family interaction styles. A pyramidal organizational design, using peer leaders, facilitated 71% of families to complete all seven sessions, whereas 84% completed at least one session. Significant independent predictors of program completion were attending an introductory Kick-Off Nite, interactive family style, additional adults in the household, married parents, being African American, earning more than 60,000 dollars, and additional children in the household. Family-specific issues and initial program experience are important considerations for implementing a family intervention.

Hi5+: systematic development of a family intervention to increase fruit and vegetable intake.

This article describes the development of a peer-led home-based intervention to increase fruit and vegetable (FV) intake and family interaction among fourth graders and their families. Hi5+ intervention content and delivery strategies were developed using two complementary processes: cognitive mapping (CM), a consumer-based approach to identifying salient issues, and intervention mapping (IM), a comprehensive planning model. Step 1 involved creating plans to guide the design, implementation, and evaluation of Hi5+. We delineated our performance objectives and then prioritized those determinants we felt were most salient and changeable. Step 2 involved selecting and utilizing cognitive and behavioral theory constructs to develop intervention methods and strategies. Step 3 involved designing and pilot testing the instructional materials and other intervention components. Step 4 entailed developing plans for program adoption and implementation, while the final step (Step 5) involved creating a comprehensive evaluation plan. Implications of this multistep approach to intervention development are discussed.

A randomized controlled trial to reduce HIV transmission risk behaviors and sexually transmitted diseases among women living with HIV: The WiLLOW Program.

OBJECTIVE: To evaluate the efficacy of an intervention to reduce HIV transmission risk behaviors and sexually transmitted diseases (STDs) and enhance HIV-preventive psychosocial and structural factors among women living with HIV. DESIGN: A randomized controlled trial of 366 women living with HIV in Alabama and Georgia. INTERVENTION: The intervention emphasized gender pride, maintaining current and identifying new network members, HIV transmission knowledge, communication and condom use skills, and healthy relationships. PRIMARY OUTCOME: Unprotected vaginal intercourse. OTHER OUTCOMES: Proportion never used condoms, incident STDs, psychosocial factors, and number of supportive network members. RESULTS: Over the 12-month follow-up, women in the WiLLOW intervention, relative to the comparison, reported fewer episodes of unprotected vaginal intercourse (1.8 vs. 2.5; P = 0.022); were less likely to report never using condoms (odds ratio [OR] = 0.27; P = 0.008); had a lower incidence of bacterial infections (Chlamydia and gonorrhea) (OR = 0.19; P = 0.006); reported greater HIV knowledge and condom use self-efficacy, more network members, fewer beliefs that condoms interfere with sex, and fewer partner-related barriers to condom use; and demonstrated greater skill in using condoms. CONCLUSION: This is the first trial to demonstrate reductions in risky sexual behavior and incident bacterial STDs and to enhance HIV-preventive psychosocial and structural factors among women living with HIV.

Efficacy of an HIV prevention intervention for African American adolescent girls: a randomized controlled trial.

CONTEXT: African American adolescent girls are at high risk for human immunodeficiency virus (HIV) infection, but interventions specifically designed for this population have not reduced HIV risk behaviors. OBJECTIVE: To evaluate the efficacy of an intervention to reduce sexual risk behaviors, sexually transmitted diseases (STDs), and pregnancy and enhance mediators of HIV-preventive behaviors. DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial of 522 sexually experienced African American girls aged 14 to 18 years screened from December 1996 through April 1999 at 4 community health agencies. Participants completed a self-administered questionnaire and an interview, demonstrated condom application skills, and provided specimens for STD testing. Outcome assessments were made at 6- and 12-month follow-up. INTERVENTION: All participants received four 4-hour group sessions. The intervention emphasized ethnic and gender pride, HIV knowledge, communication, condom use skills, and healthy relationships. The comparison condition emphasized exercise and nutrition. MAIN OUTCOME MEASURES: The primary outcome measure was consistent condom use, defined as condom use during every episode of vaginal intercourse; other outcome measures were sexual behaviors, observed condom application skills, incident STD infection, self-reported pregnancy, and mediators of HIV-preventive behaviors. RESULTS: Relative to the comparison condition, participants in the intervention reported using condoms more consistently in the 30 days preceding the 6-month assessment (unadjusted analysis, intervention, 75.3% vs comparison, 58.2%) and the 12-month assessment (unadjusted analysis, intervention, 73.3% vs comparison, 56.5%) and over the entire 12-month period (adjusted odds ratio, 2.01; 95% confidence interval [CI], 1.28-3.17; P =.003). Participants in the intervention reported using condoms more consistently in the 6 months preceding the 6-month assessment (unadjusted analysis, intervention, 61.3% vs comparison, 42.6%), at the 12-month assessment (unadjusted analysis, intervention, 58.1% vs comparison, 45.3%), and over the entire 12-month period (adjusted odds ratio, 2.30; 95% CI, 1.51-3.50; P<.001). Using generalized estimating equation analyses over the 12-month follow-up, adolescents in the intervention were more likely to use a condom at last intercourse, less likely to have a new vaginal sex partner in the past 30 days, and more likely to apply condoms to sex partners and had better condom application skills, a higher percentage of condom-protected sex acts, fewer unprotected vaginal sex acts, and higher scores on measures of mediators. Promising effects were also observed for chlamydia infections and self-reported pregnancy. CONCLUSION: Interventions for African American adolescent girls that are gender-tailored and culturally congruent can enhance HIV-preventive behaviors, skills, and mediators and may reduce pregnancy and chlamydia infection.

Relationship characteristics and sexual practices of African American adolescent girls who desire pregnancy.

This study examined associations between African American adolescent girls' desire to become pregnant and their sexual and relationship practices. Odds ratios and 95% confidence intervals were used to detect significant associations between pregnancy desire and the assessed correlates. Of 522 participants (14 to 18 years old), 67 (12.8%) were pregnant and were thus excluded from this analysis. Of the remaining 455 adolescents, 107 (23.6%) expressed some desire to be pregnant at the time of assessment. Adolescents who desired pregnancy were significantly more likely to report having had sex with a casual partner and to use contraception inconsistently. Factors involving an adolescent girl's relationship with her partner (e.g., being in a relationship, length of relationship, time spent with boyfriend, or satisfaction with boyfriend) were not significantly associated with the desire for pregnancy. Effective pregnancy and sexually transmitted disease prevention programs for female adolescents should address their level of pregnancy desire.

Identification of strategies for promoting condom use: a prospective analysis of high-risk African American female teens.

Condom promotion strategies for adolescents typically include provision of STD/HIV-associated knowledge, fostering favorable attitudes toward condom use, promoting positive peer norms regarding condom use, improving condom-related communication skills and self-efficacy, and overcoming barriers to condom use. The purpose of this study was to identify which of these constructs were prospectively associated with condom use among a high-risk sample of African American adolescent females reporting sexual activity with a steady male partner. Adolescents, 14-18 years old, were recruited from schools and health clinics. Adolescents completed an in-depth survey and interview at baseline and again 6 months later. Analyses were limited to adolescents with steady partners who reported sexual activity between the baseline and 6-month follow-up assessment periods (N = 179). At baseline, five-scale measures and a single-item measure were used to assess predictive constructs. At follow-up, adolescents were asked about their frequency of condom use over various periods of recall. Multivariate models were created to control for the confounding influence of pregnancy status. The findings were remarkably distinct. The evidence strongly supported the predictive role of perceived barriers toward condom use and peer norms. The measure of sexual communication achieved significance for two of the six assessed outcomes. Alternatively, measures of attitudes toward condom use, condom negotiation self-efficacy, and knowledge about STD/HIV-prevention were consistently nonsignificant. The findings suggest that to improve effectiveness of individual-level STD/HIV prevention programs, designed for this population, program emphasis should be on reducing barriers to condom use, teaching partner communication skills, and fostering positive peer norms relevant to condom use.

Pregnant African-American teens are less likely than their nonpregnant peers to use condoms.

OBJECTIVE: The aim of this study was to prospectively compare pregnant and nonpregnant adolescents' recent condom use and sexually transmitted disease (STD) acquisition. METHODS: Sexually active African-American females (N = 522), ages 14-18, were recruited from clinics and schools. Adolescents completed baseline interviews and provided vaginal swabs for STD testing, and urine for pregnancy testing. Assessments were repeated 6 and 12 months post baseline assessment. Analyses compared adolescents who became pregnant between baseline and the 6-month assessment with their peers who had negative pregnancy tests. Condom use between the 6- and 12-month assessments and incidence of STDs at the 12-month assessment served as outcomes. Adolescents who did not report sexual activity between the 6- and 12-month assessments were excluded. RESULTS: Ten percent of the adolescents became pregnant and continued sexual activity. Pregnant adolescents reported less overall condom use (P < 0.0001), more infrequent condom use (adjusted odds ratio [AOR] = 4.5, P < 0.001), and more unprotected vaginal sex (AOR = 4.7, P < 0.003). Pregnant adolescents were equally likely to test positive for STDs (31% vs 26%) and to self-report having STDs at the 12-month follow-up period (30% vs 23%). CONCLUSIONS: Findings suggest that pregnant adolescents may be less likely to use condoms than their nonpregnant peers and that STD incidence among pregnant adolescents may be high. Condom use promotion may be important during adolescents' prenatal care.

Psychosocial and behavioral correlates of refusing unwanted sex among African-American adolescent females.

PURPOSE: To identify psychosocial and behavioral correlates of refusing unwanted sex among African-American female adolescents. We hypothesized that greater power in relationships, less concern about negative emotional consequences, supportive family and peers, positive self-perceptions, greater perceived risk, and fewer sexual risk behaviors would be associated with increased odds of refusing unwanted sex. METHODS: Data regarding demographics, sexual behaviors, communication with parents, and psychosocial factors relevant to romantic and sexual partnerships were collected both via self-administered questionnaire and structured interview from a clinic- and school-based sample of 522 African-American adolescent females ages 14-18 years in Birmingham, Alabama. Adjusted odds ratios were calculated using logistic regression. RESULTS: Of those who had experienced pressure for unwanted sex (n = 366), 69% consistently refused to engage in unwanted sex. Adolescents with high safer sex self-efficacy and low perceived partner-related barriers (i.e., concerns about partners' negative emotional reactions) to condom negotiation were over 2.5 times more likely to consistently refuse unwanted sex than were those reporting low safer sex self-efficacy and high partner-related barriers. Adolescents who spoke more frequently with their parents about sexual issues were nearly twice as likely to consistently refuse unwanted sex than were those who spoke less frequently with their parents. CONCLUSIONS: Sexual-risk reduction efforts directed toward adolescent females should seek to build self-efficacy to negotiate safer sex and provide training in social competency skills that may help to reduce or eliminate partner barriers to condom use. Further, sexual risk-reduction programs may be more effective if they include parents as advocates of safer sexual behaviors.

Adolescents' ambivalence about becoming pregnant predicts infrequent contraceptive use: a prospective analysis of nonpregnant African American females.

This study prospectively investigated the hypothesis that ambivalence about becoming pregnant is associated with comparatively less frequent use of contraception. Findings from a sample of sexually active African American adolescent, nonpregnant females (n = 375) supported this hypothesis. Prevention programs may benefit from content designed to redress adolescents' positive beliefs about early parenthood.

Body image and African American females' sexual health.

OBJECTIVES: This study examines the association between African American adolescent females' body image and their sexual health. METHODS: African American adolescent females (n = 522) completed a survey that assessed body image using a 7-item scale (alpha = 0.71) and a face-to-face interview that assessed sexual behaviors. RESULTS: In logistic regression analyses, controlling for depression, self-esteem and body mass index (BMI), adolescents who were more dissatisfied with their body image were more likely to fear abandonment as a result of negotiating condom use (adjusted odds ratio [AOR] = 3.3, p = 0.02), more likely to perceive that they had fewer options for sexual partners (AOR = 2.4, p = 0.001), more likely to perceive themselves as having limited control in their sexual relationships (AOR = 2.0, p = 0.002), and more likely to worry about acquiring HIV(AOR = 1.5, p = 0.04). There was an association between having a greater dissatisfaction with one's body image and never using condoms during sexual intercourse in the past 30 days (AOR = 1.6, p = 0.04) and more likely to engage in unprotected vaginal sex in the prior 6 months (AOR = 1.6, p = 0.04). CONCLUSIONS: Prior research has demonstrated an association between African American women's body image and greater obesity risk, lower self-esteem, and greater depression. The present study has shown an association between body image dissatisfaction and a range of sexual attitudes, beliefs, and behaviors. Women who are more dissatisfied with their body image may be at greater risk for unintended pregnancy, sexually transmitted infections (STIs), and HIV infection.

Sexual risk behaviors associated with having older sex partners: a study of black adolescent females.

BACKGROUND: Volunteer black adolescent females from neighborhoods characterized by high rates of unemployment, substance abuse, violence, and sexually transmitted disease were studied to determine the frequency of condom use and unprotected vaginal sex with steady, older partners during various time periods over the previous 6 months. GOAL: To examine associations between having male sex partners who were typically older (by at least 2 years) and adolescent females' sexually transmitted disease (STD)/HIV-associated sexual risk behaviors. STUDY DESIGN: In this cross-sectional study, 522 sexually active black adolescent females completed a questionnaire and a structured interview, of which a portion assessed the age difference between the adolescents and their typical sex partners. The adolescents' ages, length of relationship and their use of hormonal contraception were identified as covariates. Adjusted odds ratios (AOR), their 95% confidence intervals, and respective P values were calculated to detect significant associations. RESULTS: Sixty-two percent of the adolescents reported their typical sex partners were at least 2 years older. These adolescents were more likely to report never using condoms during the most recent sexual encounter (AOR = 2.0), during the last five sexual encounters (AOR = 2.0), and during the past month (AOR = 2.2). Similarly, having older partners was associated with greater odds of reporting any unprotected vaginal sex in the past 30 days (AOR = 1.7) or the past 6 months (AOR = 1.5). CONCLUSION: Our findings suggest that many adolescent females have sex partners who are at least 2 years older and that their relationship dynamics do not favor the adoption and maintenance of behavior protective against STD or HIV infection. Prevention programs could include training designed to help adolescent females overcome barriers to safer sex with older male partners.

Associations between biologically confirmed marijuana use and laboratory-confirmed sexually transmitted diseases among African American adolescent females.

BACKGROUND: Numerous studies have examined the association between adolescents' marijuana use and their high-risk sexual behaviors and sexually transmitted diseases (STDs). However, the validity of the findings is questionable because most of the studies relied on self-reporting for measurement of marijuana use and key outcome (i.e., STDs). GOAL: The goal was to investigate associations between biologically confirmed marijuana use and laboratory-confirmed STDs and condom use. STUDY DESIGN: African American females adolescents (n = 522) completed a self-administered survey and face-to-face interview. The adolescents provided urine and vaginal swab specimens that were analyzed for marijuana metabolites and STDs, respectively. RESULTS: Among the study subjects, 5.4% tested positive for marijuana. These adolescents were more likely to test positive for Neisseria gonorrhoeae (adjusted odds ratio [AOR] = 3.4) and Chlamydia trachomatis (AOR = 3.9). They were more likely to have never used condoms in the previous 30 days (AOR = 2.9) and to have not used condoms consistently in the previous 6 months (AOR = 3.6). CONCLUSION: The findings represent unique biologic evidence that STDs and sexual risk behavior may co-occur with marijuana use. Interventions designed to reduce adolescents' risk of STDs and HIV infection should address marijuana use.

Condom use and correlates of African American adolescent females' infrequent communication with sex partners about preventing sexually transmitted diseases and pregnancy.

This study of 522 African American female adolescents, ages 14 to 18, investigated associations between condom use and infrequently communicating with sex partners about sexually transmitted diseases (STDs) and pregnancy prevention. Correlates of infrequent communication were identified. Sexually active adolescents were recruited from schools and adolescent medicine clinics in low-income neighborhoods of Birmingham, Alabama. Adolescents completed a self-administered survey and face-to-face interview. Communication frequency was assessed using a five-item scale. Infrequent communication was significantly associated with lower odds of condom use. Multivariate correlates of infrequent communication were less frequent communication with parents about STD/pregnancy prevention, recent sex with a nonsteady partner, low perceived ability to negotiate condom use and fear of this negotiation, and low motivation to use condoms. Given the importance of partner communication in promoting safer sex behaviors, STD and pregnancy prevention programs may benefit adolescents by addressing the identified psychosocial correlates of infrequent communication with their partners.

Gang involvement and the health of African American female adolescents.

OBJECTIVE: To examine the association between gang involvement and female adolescents' health. METHODS: African American adolescent females (N = 522) completed a survey that assessed their history of gang involvement and health behaviors and provided specimens that were analyzed for marijuana use and sexually transmitted diseases. RESULTS: In logistic regression analyses, adolescents with a history of gang involvement were more likely to have been expelled from school (odds ratio [OR]: 3.6), be a binge drinker (OR: 3.3), have a positive toxicologic test for marijuana (OR: 2.6), have been in 3 or more fights in the past 6 months (OR: 3.8), have a nonmonogamous partner (OR: 2.4), and test positive for Trichomonas vaginalis (OR: 2.2) and Neisseria gonorrhoeae (OR: 3.6). CONCLUSION: This study extends the current research on risk behaviors associated with gang involvement to include biological markers for substance use and sexual health outcomes, namely, marijuana use and sexually transmitted diseases.

Pregnancy desire among disadvantaged African American adolescent females.

OBJECTIVE: To examine the prevalence and correlates of wanting to become pregnant among a sample of 462 sexually active nonpregnant African American adolescent females. METHODS: Multivariate logistic regression was used to calculate adjusted odds ratios, their 95% confidence intervals, and respective P values. RESULTS: Significant correlates with pregnancy desire included having a male partner who desired pregnancy, having a boyfriend at least 5 years older, having low self-esteem, perceiving greater perceived barriers to condom use, and perceiving low family support. CONCLUSIONS: Pregnancy prevention programs designed for economically disadvantaged African American adolescent females should address these correlates of their pregnancy desire.

Using cognitive mapping to develop a community-based family intervention.

OBJECTIVE: To describe the development of a consumer-oriented intervention for increasing intake of fruits and vegetables (FVs) in families (n=265). METHOD: A cognitive-mapping approach was used to specify intervention performance objectives and a tailoring strategy. RESULTS: MDS and hierarchical cluster analysis indicated that FV perceptions are organized into 6 clusters arrayed along 3 dimensions. In combination with 3 general family-functioning measures, 11 perceptions explained approximately 18% of the variance in parent FVI. K-means cluster analysis revealed 4 types of families. CONCLUSION: Cognitive mapping provides a systematic approach for including qualitative data in the design of tailored interventions.
