Predictors of sexual risk behaviors among adolescent mothers in a human immunodeficiency virus prevention program

Effect of sexual health education on sexual function and satisfaction of menopausal migrant women: an application of the theory of planned behavior

OBJECTIVES

This study investigated the effect of an intervention based on the theory of planned behavior on sexual function and satisfaction of migrant women during menopause in Iran.

METHODS

This quasi-experimental study was conducted on 88 migrant and menopausal women in Iran. Sampling was performed using the multistage methods in four health care centers. The educational program based on the theory of planned behavior was held in 4 sessions of 90 min for 4 weeks in the intervention group. The final evaluation of the intervention was performed immediately, and the follow-up stage (3 months after the intervention) by completing questionnaires in two groups. The data was analyzed with SPSS 20 software with statistical tests of mean and standard deviation, Manwitney, Frideman, Generalized Estimating Equations.

RESULTS

The results showed that after the intervention, the mean score of sexual function in the intervention group increased from 16.53 ± 2.68 before to 17.52 ± 2.90 immediately and 17.38 ± 2.81 in follow up stage (p < 0.05). But in the control group, this score was not statistically significant during the study stages (p > 0.05).

CONCLUSION

The results indicate that the intervention based on the theory of planned behavior is effective in sexual function and satisfaction with the married life of migrant women during menopause. but to change the sexual function, studies with a longer duration and also the use of other educational models are suggested.

Depression, Abuse, Relationship Power and Condom Use by Pregnant and Postpartum Women with Substance Abuse History

Substance-abusing pregnant and postpartum women are less likely to maintain consistent condom use and drug and alcohol abstinence, which is particularly concerning in high HIV-prevalence areas. Data from 224 pregnant and postpartum women in substance abuse treatment were analyzed to examine effects of history of substance use, child abuse, and mental health problems on current substance use and condom-use barriers. Mediators were depression, relationship power and social support. Most participants (72.9 %) evidenced current depression. Less social support (-0.17, p < 0.05) and relationship power (-0.48, p < 0.001), and greater depression (-0.16, p < 0.05) predicted more condom-use barriers. History of mental health problems predicted condom-use barriers, mediated by recent depression and relationship power (0.15, p < 0.001). These findings suggest depression and diminished relationship power limit highest-risk women's ability to negotiate condom use and abstain from substance use, increasing their risk of acute HIV infection and vertical transmission.

Reproductive Health CHOICES for Young Adults with Sickle Cell Disease or Trait: Randomized Controlled Trial Outcomes over Two Years

Interventions to assist reproductive health decision-making in populations affected by sickle cell disease (SCD) or trait (SCT) lack proven efficacy over time. Our aim was to compare effects of CHOICES, a Web-based multimedia education program on implementing informed reproductive plans, and usual care education (e-Book) on reproductive knowledge, intention, and behavior over 24 months. We randomized 234 participants with SCD (n = 138) or SCT (n = 96) (age 18-35 years, 35 % male, 94 % African American) to CHOICES and e-Book groups. Participants completed a sickle cell-specific reproductive measure before and four times after the intervention (6, 12, 18 and 24 months). Compared to the e-Book group the CHOICES group had significantly more improvement in knowledge over time (p = .004) but not intention (p = .18) or behavior (p = .69). At baseline, 114 (48.7 %) participants reported having partners who would not put the couple at risk for their children inheriting SCD. Of the 116 (49.6 %) at-risk participants, a higher poroportion of those who were in the CHOICES group chose partners that reduced their risk by the last visit than the e-Book group (p = .04). Study findings provide important insights for designing a national trial of the CHOICES intervention focusing on subjects whose partner status puts them at risk for having a child with SCD.

A Path Analysis of Latino Parental, Teenager and Cultural Variables in Teenagers' Sexual Attitudes, Norms, Self-Efficacy, and Sexual Intentions

OBJECTIVE

to test a theoretical model based on the Parent-Based Expansion of the Theory of Planned Behavior examining relation between selected parental, teenager and cultural variables and Latino teenagers' intentions to engage in sexual behavior.

METHOD

a cross-sectional correlational design based on a secondary data analysis of 130 Latino parent and teenager dyads.

RESULTS

regression and path analysis procedures were used to test seven hypotheses and the results demonstrated partial support for the model. Parent familism and knowledge about sex were significantly associated with parents' attitudes toward sexual communication with their teenagers. Parent Latino acculturation was negatively associated with parents' self-efficacy toward sexual communication with their teenagers and positevely associated with parents' subjective norms toward sexual communication with their teenagers. Teenager knowledge about sex was significantly associated with higher levels of teenagers' attitudes and subjective norms about sexual communication with parents. Only the predictor of teenagers' attitudes toward having sex in the next 3 months was significantly associated with teenagers' intentions to have sex in the next 3 months.

CONCLUSION

the results of this study provide important information to guide future research that can inform development of interventions to prevent risky teenager sexual behavior among Latinos.

Reproductive health choices for young adults with sickle cell disease or trait: randomized controlled trial immediate posttest effects

BACKGROUND

People with sickle cell disease (SCD) or sickle cell trait (SCT) may not have information about genetic inheritance needed for making informed reproductive health decisions. CHOICES is a Web-based, multimedia educational intervention that provides information about reproductive options and consequences to help those with SCD or SCT identify and implement an informed parenting plan. Efficacy of CHOICES compared with usual care must be evaluated.

OBJECTIVE

The purpose was to compare immediate posttest effects of CHOICES versus an attention-control usual care intervention (e-Book) on SCD-/SCT-related reproductive health knowledge, intention, and behavior.

METHODS

In a randomized controlled study, we recruited subjects with SCD/SCT from clinics, community settings, and online networks with data collected at sites convenient to the 234 subjects with SCD (n = 136) or SCT (n = 98). Their ages ranged from 18 to 35 years; 65% were women, and 94% were African American. Subjects completed a measure of sickle cell reproductive knowledge, intention, and behavior before and immediately after the intervention.

RESULTS

Compared with the e-Book group, the CHOICES group had significantly higher average knowledge scores and probability of reporting a parenting plan to avoid SCD or SCD and SCT when pretest scores were controlled. Effects on intention and planned behavior were not significant. The CHOICES group showed significant change in their intention and planned behavior, whereas the e-Book group did not show significant change in their intention, but their planned behavior differed significantly.

DISCUSSION

Initial efficacy findings are encouraging but warrant planned booster sessions and outcome follow-ups to determine sustained intervention efficacy on reproductive health knowledge, intention, and actual behavior of persons with SCD/SCT.

Risky sexual behaviors in emerging adults: longitudinal changes and within-person variations

This study examined longitudinal changes in condom use inconsistency and sexual encounters involving alcohol use and the within-person associations of these two risky sexual behaviors with other personal and contextual factors. Data were drawn from a sample of college students who completed surveys on four occasions across 3 years and included 317 participants (48 % male; 32 % African American, 28 % Latino American, and 40 % European American) who reported recent penetrative sexual activities on at least one of the occasions. Multilevel models revealed that, although condom use inconsistency increased and then leveled off over time, sexual encounters involving alcohol use showed a linear increase. Moreover, at times when students held more negative attitudes toward condoms than usual, they used condoms less consistently than usual; at times when students felt more anxious about HIV/AIDS than usual, they had more sexual encounters involving alcohol use than usual; and at times when students were involved in a serious relationship, they used condoms less consistently and had fewer sexual encounters involving alcohol use than usual. Findings demonstrate the utility of a developmental perspective in understanding sexual behaviors, the importance of examining the unique correlates of different risky sexual behaviors, and the distinctiveness between within-person versus between-person associations.

Moderation and mediation of an effective HIV risk-reduction intervention for South African adolescents

BACKGROUND

"Let Us Protect Our Future" is a sexual risk-reduction intervention for sixth-grade adolescents in South Africa. Tested in a cluster-randomized controlled trial, the intervention significantly reduced self-reported intercourse and unprotected intercourse during a 12-month follow-up period.

PURPOSE

The present analyses were conducted to identify moderators of the intervention's efficacy as well as, which theory-based variables mediated the intervention's effects.

METHODS

Intervention efficacy over the 3-, 6-, and 12-month follow-up was tested using generalized estimating equation models.

RESULTS

Living with their father in the home, parental strictness, and religiosity moderated the efficacy of the intervention in reducing unprotected intercourse. Self-efficacy to avoid risky situations and expected parental disapproval of their having intercourse, derived from Social Cognitive Theory, significantly mediated the intervention's effect on abstinence.

CONCLUSIONS

This is the first study to demonstrate that Social Cognitive variables mediate the efficacy of a sexual risk-reduction intervention among South African adolescents.

Cross-cultural variations in adolescents' perceived maternal expectancy and sexual initiation

PURPOSE

This study built on previous findings and compared the effects of maternal influences on adolescents' sexual initiation among four racial and ethnic groups: Asian American Pacific Islanders, African Americans, Hispanic Americans, and Caucasians.

DESIGN

An exploratory, comparative secondary analysis of longitudinal data from 433 Asian American Pacific Islanders, 1,367 African Americans, 1,241 Hispanic Americans, and 4,567 Caucasian adolescents between the ages of 15 and 17 years at Wave 1 was conducted using structural equation modeling. Bronfenbrenner's Social Ecological Model guided the modeling and analyses.

RESULTS

Adolescents' sexual initiation was significantly associated with mother-adolescent interactions and adolescents' perceived maternal sexual expectations. Cross-cultural variations are noted and discussed.

CONCLUSIONS

Nursing interventions designed to delay adolescents' sexual initiation need to focus on familial and cultural variations associated with mother-adolescent interactions.

Sorting through chickens and eggs: a longitudinal examination of the associations between attitudes, norms, and sexual risk behavior

OBJECTIVE

Health behavior theories posit that health-relevant attitudes, beliefs, and behavioral skills drive subsequent actions people take to protect themselves from health threats. Within the realm of HIV-related sexual risk behavior, much of the research in support of this notion is cross-sectional, rather than longitudinal, particularly in studies of gay and bisexual men. Other psychological theories (e.g., self-perception or cognitive dissonance theories) suggest that the opposite could be true--that health-relevant attitudes and beliefs might change as a function of previous risk or precautionary behavior. Appreciating the complex nature of these associations is essential for modifying theory and developing appropriate interventions.

DESIGN

Using longitudinal data from gay and bisexual men (n = 1465), we used structural equation modeling to examine three possibilities--that perceived norms and attitudes about sexual risk would be (a) related to unprotected anal intercourse cross-sectionally, (b) related to unprotected anal intercourse at a subsequent time point, and/or (c) predicted from previous instances of unprotected anal intercourse.

RESULTS

Safe-sex norms and attitudes were related to unprotected anal intercourse cross-sectionally, but did not predict unprotected sex longitudinally. Rather, perceived norms and attitudes changed as a function of previous risk behavior.

CONCLUSIONS

These results raise the possibility that modified theoretical models might be necessary to adequately describe sexual risk behavior among gay and bisexual men.

Evaluation of an intervention to increase human immunodeficiency virus testing among youth in Manzini, Swaziland: a randomized control trial

There is an urgent need for effective HIV prevention programs for adolescents in Swaziland, given the high prevalence of HIV and lack of HIV-related knowledge and skills among Swazi youth. This study set out to determine whether an HIV education intervention designed in the United States, and adapted for Swaziland, would be effective in changing participants' HIV-related knowledge, attitudes, and protective behaviors including HIV testing. We also explored whether the components of Self-Efficacy Theory are associated with these behaviors. Data were obtained from 135 students who participated in a school-based program. The study found significant differences between the intervention and control groups regarding HIV knowledge, self-efficacy for abstinence, condom use, and getting HIV test results, outcome expectations for knowing one's own HIV status, and the protective behavior of getting an HIV test. This is evidence that school-based HIV education programs can successfully increase HIV testing among in-school youth in Swaziland.

An extended model of reasoned action to understand the influence of individual- and network-level factors on African Americans' participation in HIV vaccine research

In the United States, the number and proportion of HIV/AIDS cases among black/African Americans continue to highlight the need for new biomedical prevention interventions, including an HIV vaccine, microbicide, or new antiretroviral (ARV) prevention strategies such as pre-exposure prophylaxis (PrEP) to complement existing condom usage, harm reduction methods, and behavioral change strategies to stem the HIV epidemic. Although black/African Americans are disproportionately impacted by HIV/AIDS, their participation in HIV clinical research continues to have unique challenges. We theorize that interaction among multilevel factors creates ideal alignment for minority participation in HIV clinical studies. Thus, we initially set out to test an extended model of reasoned action with 362 participants to understand the interplay of sociopsychological and network-level considerations influencing minority participation in HIV prevention research efforts. In this study, we linked the intrapersonal dimensions of attitudes, beliefs, and normative concerns to community-level components, appraisal of involvement with the clinical research organization, an entity which operates within a networked structure of community partner agencies, and identification with coalition advocacy aims. Various participatory outcomes were explored including involvement in future HIV vaccine community functions, participation in community promotion of HIV vaccine research, and community mobilization. Three-stage least squares estimates indicated similar findings across three models. Significant effects demonstrate the importance of positive attitudes toward HIV vaccine research, favorable health research beliefs, perceived social support for participation, HIV/AIDS issue engagement, and perceived relevance of the clinical research site's mission and values. Identification of these nuanced pathway effects provides implications for tailored community program development.

The Role of Communication with Friends in Sexual Initiation

This study identifies a theoretical mechanism through which communication with friends about sex influences sexual initiation in a sample of adolescents. The Integrative Model was used to assess the effect of attitudes, normative pressure and self efficacy on intentions to have sex in a sample of virgin adolescents. Results show that the constructs of the theory partially mediated the effect of communication with friends on subsequent sexual initiation. The effect of communication with friends on sexual initiation was not different for males and females. Overall, the results suggest how conversations with friends about sex influence adolescents' intentions to initiate sexual intercourse, which in turn influence subsequent sexual initiation.

Theory-based interventions for contraception

BACKGROUND

The explicit use of theory in research helps expand the knowledge base. Theories and models have been used extensively in HIV-prevention research and in interventions for preventing sexually transmitted infections (STIs). The health behavior field uses many theories or models of change. However, educational interventions addressing contraception often have no stated theoretical base.

OBJECTIVES

Review randomized controlled trials that tested a theoretical approach to inform contraceptive choice; encourage contraceptive use; or promote adherence to, or continuation of, a contraceptive regimen.

SEARCH STRATEGY

We searched computerized databases for trials that tested a theory-based intervention for improving contraceptive use (MEDLINE, POPLINE, CENTRAL, PsycINFO, EMBASE, ClinicalTrials.gov, and ICTRP). We also wrote to researchers to find other trials.

SELECTION CRITERIA

Trials tested a theory-based intervention for improving contraceptive use. We excluded trials focused on high-risk groups. Interventions addressed the use of one or more contraceptive methods. The reports provided evidence that the intervention was based on a specific theory or model. The primary outcomes were pregnancy, contraceptive choice, initiating or changing contraceptive use, contraceptive regimen adherence, and contraception continuation.

DATA COLLECTION AND ANALYSIS

The primary author evaluated abstracts for eligibility. Two authors extracted data from included studies. We calculated the odds ratio for dichotomous outcomes and the mean difference for continuous data. No meta-analysis was conducted due to intervention differences.

MAIN RESULTS

Of 26 trials, 12 interventions addressed contraception (other than condoms), while 14 focused on condom use for preventing HIV or STIs. In 2 of 10 trials with pregnancy or birth data, a theory-based group showed better results. Four of nine trials with contraceptive use (other than condoms) showed better outcomes in an experimental group. For condom use, a theory-based group had favorable results in 14 of 20 trials, but the number was halved in a subgroup analysis. Social Cognitive Theory was the main theoretical basis for 12 trials, and 10 showed positive results. Of the other 14 trials, favorable results were shown for other social cognition models (N=2), motivational interviewing (N=5), and the AIDS Risk Reduction Model (N=2). No major patterns were detected by type of theory, intervention, or target population.

AUTHORS' CONCLUSIONS

Family planning researchers and practitioners could apply the relevant theories and effective interventions from HIV and STI prevention. More thorough use of single theories would help inform the field about what works. Better reporting is needed on research design and intervention implementation.

Testing a model of contraception use behavior among sexually active female adolescents in Taiwan

The purpose of this cross-sectional study was to test a model of contraception use among sexually active Taiwanese female adolescents, using structural equation modeling. Anonymous questionnaires were distributed to 404 female adolescents who had had sexual intercourse in the previous 3 months. A model was produced in which past contraception use, self-efficacy for contraception use, and decisional balance for using contraception had significant direct effects on current contraception use. Social influences had not only significant direct effects on self-efficacy and on decisional balance, but also a significant indirect effect on current contraception use. These findings provide a reference for the development of contraceptive intervention programs for sexually active female adolescents in Taiwan.

Relationship, power, and other influences on self-protective sexual behaviors of African American female adolescents

This study examined risky sexual behaviors, gender, and power issues affecting risk taking, and factors most likely to promote self-protection among female African American adolescents. A cross-sectional design was used for data collection. The sample included 130 adolescents ranging from 14 to 20 years of age, who completed questionnaires. Multiple regression analysis resulted in two models that accounted for 23% and 37% of the variance. Behavioral intention, partner age, pregnancy status, current substance use, and length of sexual relationship were statistically significant predictor variables. Behavioral intentions, in particular, were found to be a strong predictor of condom use among African American youth.
