While overall HIV prevalence in Malawi has decreased, it is still high in the southern region of the country. Behavioral prevention activities are crucial to continue the reduction in HIV prevalence. Behavior change is influenced by many factors. Previous work indicates knowledge about HIV transmission, self-efficacy to protect oneself from exposure, and accurate risk perception of one's susceptibility all impact sexual behavior. The current study looks at the effects of a behavior change communication program in Malawi called the BRIDGE II Project on psychosocial and behavioral variables. The program sought to address barriers to individual action and confront societal norms related to sexual risk behavior through a mix of community-based activities and mass media messages delivered through local radio stations. Using cohort data (n = 594), we examined the effect of BRIDGE exposure on three variables that affect HIV behaviors: knowledge, self-efficacy, and risk perception, as well as two behavioral outcomes: HIV testing and condom use at last sex. Data were collected at baseline and for a midterm evaluation. Regression analyses showed exposure to BRIDGE was significantly associated with knowledge level (β = 0.20, p < .001) and self-efficacy (β = 0.35, p < .001) at midterm when controlling for baseline scores, but not risk perception. Psychosocial variables did not show a significant relationship to either behavioral outcome. However, program exposure was a significant predictor of both HIV testing in the past year (odds ratio [OR] = 1.40, p < .001) and condom use at last sex (OR = 1.26, p < .05). This study suggests such a communication intervention may play an important role in not only affecting HIV-related behaviors themselves, but also critical factors that affect HIV behaviors, including knowledge and self-efficacy. It is recommended that communication efforts around HIV risk reduction be increased.  相似文献

Potential for widespread transmission of HIV/AIDS among American Indian (AI) adolescents exists, yet no evidence-based interventions (EBIs) have been adapted and evaluated with this population. Intensive psychoeducation may improve knowledge and decision-making which could potentially translate to reductions in HIV risk behaviors. A peer group randomized controlled comparison of an adapted EBI vs. control was delivered over an eight-day summer basketball camp in one reservation-based tribal community to adolescents ages 13–19. Outcome data were gathered immediately post-camp and at 6 and 12 months follow-up. Self-selected peer groups were randomized to intervention (n = 138) or control (n = 129) conditions for a total sample of 267 participants (56.2% female), mean age 15.1 years (SD = 1.7). Intervention participants had better condom use self-efficacy post-camp (Adjusted Mean Difference [AMD] = ?0.75, p < 0.005) and at 6 (AMD = ?0.44, p < 0.005) and 12 months (AMD = ?0.23, p < 0.05) follow-up. Intervention participants also had higher HIV prevention and transmission knowledge (post-camp: AMD = 0.07, p < 0.01; 6 months: AMD = 0.06, p < 0.01) were more likely to believe condoms prevent sexually transmitted infections (post-camp: RR = 1.41, p < 0.005; 6 months: RR = 1.34, p < 0.05), to talk with an adult about HIV/AIDS (post-camp: RR=1.78, p < 0.005; 6 months: RR = 1.14, p < 0.005), had higher partner negotiation efficacy related to substance use during sex (post-camp: AMD = 0.37, p < 0.01), and were more likely to intend to use a condom (post-camp: RR = 1.39, p < 0.01). The adapted intervention had short- and medium-term impacts on AI adolescent risk for HIV/AIDS, but attenuated at 12 months. Intervention delivery through a community-based camp is feasible and acceptable with strong retention. Additional study is needed to evaluate the adapted intervention's impact on sexual risk behaviors and if booster sessions and parent involvement translate to long-term impacts.  相似文献

This paper describes the rationale, design, methods, and baseline results of a randomized controlled trial to evaluate the impact of an adapted evidence-based intervention (EBI), “Respecting the Circle of Life” (RCL) to reduce behavioral risks for HIV/AIDS among American Indian (AI) adolescents. A participatory approach shaped intervention adaptation and study design. A total of 267 participants (aged 13–19) were randomized by peer groups of the same sex to receive the RCL intervention or a control condition. Self-report assessments were administered at four intervals. The sample was predominately female (57%), had low HIV knowledge prevention scores, early sexual initiation (mean 14.6 years), and 56% reported intention to use a condom at next sex. Baseline characteristics were evenly distributed between groups with the exception of age and extrinsic reward scores. This is the first rigorous evaluation of an adapted EBI for HIV/AIDS prevention among AI adolescents, an at-risk and understudied population.  相似文献

HIV prevention interventions that reduce sexual risk behaviors among young Black men who have sex with men (YBMSM), the most severely affected population in the United States, are critical for reducing disparities in HIV infection. However, there are few theory-based sexual risk reduction interventions designed specifically for YBMSM. This study tested the applicability of the Integrated Behavioral Model (IBM), which theorizes that behavioral intentions mediate the relationship between psychosocial constructs and health behavior on condomless anal intercourse (CAI) among YBMSM. To test key constructs of the IBM, analyses were conducted with baseline data from the HealthMpowerment (HMP) randomized controlled trial. Logistic regression was used to examine the relationships between condom use self-efficacy, norms, attitudes, intentions, and environmental constraints, and CAI. Mediation analysis was conducted to determine if condom use intentions mediated the relationship between psychosocial constructs (i.e., condom use self-efficacy, norms, and attitudes) and CAI. Overall 55.7% reported one or more acts of CAI with a male partner in the past 3 months. Those who reported CAI in the 3 months prior to the baseline survey reported lower self-efficacy for condom use, lower condom use norms, more negative attitudes toward condom use, and lower condom use intentions at baseline than those who reported no CAI. In mediation analysis, the relationships between CAI and self-efficacy for condom use (estimated indirect effect?=??0.004 (SE?=?0.002)), condom use norms (?0.002 (SE?=?0.001)) and attitudes toward condom use (?0.005 (SE?=?0.002)) were mediated by condom use intentions. This study applied the IBM to sexual risk behavior among a sample of YBMSM. Results indicate that the relationships between condom use self-efficacy, norms, and attitudes, and CAI were mediated by condom use intentions. Future theory-informed interventions should focus on increasing self-efficacy for condom use, condom use norms, attitudes toward condom use, and condom use intentions to reduce CAI among YBMSM.  相似文献

Background: HIV and sexually transmitted infections (STIs) disproportionately affect women who experience intimate partner violence (IPV). Objective: The current study (1) applied a syndemic framework to study the collective effects of problematic drug use, hazardous drinking, depression, and posttraumatic stress disorder (PTSD) on fear of condom negotiation, condom negotiation, and condom use and (2) evaluated condom negotiation (controlling for fear of condom negotiation) as a mediator of the association between syndemic severity and condom use among low-income IPV-exposed women. Methods: Participants were 158 women living in the community and experiencing ongoing IPV who completed face-to-face, computer-assisted interviews. Results: Almost three-fourths of the participants reported problematic drug use, hazardous drinking, depression, and/or PTSD; many of these factors were correlated, indicating a syndemic. Multivariate logistic and linear regression analyses revealed associations between syndemic severity and fear of condom negotiation (OR?=?1.57, p?=?.02), condom negotiation (β?=??8.51, p?=?.001), and condom use (β?=??8.26, p?=?.01). Meditation analyses identified condom negotiation as a mediator of the association between syndemic severity and condom use (effect?=??6.57, SE?=?2.01, [95% CI: ?10.66, ?2.77]). Conclusions: Results fill a critical gap in previous research by identifying condom negotiation as a mechanism through which this syndemic affects condom use. Prevention and intervention programs should consider addressing condom negotiation to reduce sexual risk among this high-risk population. Further, because IPV-exposed women may experience fear related to condom negotiation, it is critical that prevention and intervention efforts for this population offer skills to safely negotiate condom use, increase condom use, and reduce STI and HIV risk.  相似文献

Vulnerability to Human Immunodeficiency Virus (HIV) infection among factory workers is a global problem. This study investigated the effectiveness of an intervention to increase AIDS knowledge, perceived accessibility to condoms and condom use among young factory workers in Thailand. The intervention was a workplace program designed to engage the private sector in HIV prevention. A cross-sectional survey conducted in 2008 to measure program outcomes in factories in Thailand was used in this study. The workplace intervention included the development of policies for management of HIV-positive employees, training sessions for managers and workers, and distribution of educational materials and condoms. A multi-level analysis was used to investigate the effect of HIV/AIDS prevention program components at the workplace on HIV/AIDS knowledge, perceived accessibility to condoms and condom use with regular sexual partners among 699 young factory workers (aged 18–24 years), controlling for their individual socio-demographic characteristics. Interventions related to the management and services component including workplace AIDS policy formulation, condom services programs and behavioral change campaigns were found to be significantly related to increased AIDS knowledge, perceived accessibility to condoms and condom use with regular partners. The effect of the HIV/AIDS training for managers, peer leaders and workers was positive but not statistically significant. With some revision of program components, scaling up of workplace interventions and the engagement of the private sector in HIV prevention should be seriously considered.  相似文献

The purpose of this study is to evaluate the association between utilization of HIV testing and condom use amongst Cameroonian youths/adolescents who are not known to be HIV-infected. Worldwide, HIV is spreading most quickly amongst youths/adolescents. Between 44% and 82% of sexually active youths in Cameroon report inconsistent condom use. Data regarding utilization of HIV testing and condom use are lacking. A cross-sectional survey was administered to 431 youths ages 12–26 years in Cameroon from September 2011 to December 2011. Data on sociodemographics, sexual risk behaviors, self-reported HIV status, and condom use were collected. We compared rates of inconsistent condom use between those with known HIV negative status who utilized testing (HIV-N) and those with unknown status due to unutilized testing (HIV-U). Inconsistent condom use was defined as responding “never,” “sometimes,” or “usually,” while consistent condom use was defined as responding “always” to questions regarding frequency of condom use. Generalized estimating equations were applied to assess the association between HIV testing and inconsistent condom use, adjusting for other confounders. Of 414 eligible respondents, 205 were HIV-U and 209 were HIV-N. HIV-U subjects were younger (mean age = 16.4 vs. 17.9, p < 0.001) and more likely to report living in an urban area (p = 0.002) than HIV-N subjects. Seventy-two percent (137/191) of sexually active youths reported inconsistent condom use. After adjusting for potential confounders, HIV-U status (odds ratio [OR] = 3.97, 95% confidence interval [CI] = 1.68–6.01) was associated with inconsistent condom use. Similarly, female gender (OR = 3.2, 95% CI = 1.29–7.89) was associated with inconsistent condom use, while older age at sexual debut was associated with a decreased risk for inconsistent condom use (OR = 0.67, 95% CI = 0.56–0.81). Cameroonian adolescents report high rates of inconsistent condom use which we found to be associated with self-reported unknown HIV status due to unutilized HIV testing. Successful HIV prevention programs among African youths/adolescents may benefit from expanded HIV testing programs.  相似文献

The purpose of the current study is to describe the demographic, behavioral, and psychosocial characteristics of adolescent and caregiver lay health advisers (LHAs) participating in an intervention designed to reduce risk behaviors among rural African-American adolescents. Teach One, Reach One integrates constructs from the Theory of Planned Behavior and Social Cognitive Theory. It acknowledges that changing the sexual behaviors of African-American adolescents requires changing one's knowledge, attitudes, normative beliefs about the behavior of peers, and self-efficacy regarding adolescent sexual behavior, parent–teen communication about sex, and healthy dating relations among adolescents. Study participants completed baseline questionnaires assessing demographics and psychosocial determinants (knowledge, attitudes, perceived social norms, and self-efficacy) of sexual behaviors. Sixty-two adolescent and caregiver dyads participated. Caregivers included biological parents, legal guardians, or other parental figures. Strengths and areas in need of improvement were determined using median splits. Few adolescents had initiated sex. Their strengths included high levels of open parent–teen communication; positive attitudes and normative beliefs regarding both sex communication and healthy dating relationships; and high knowledge and self-efficacy for healthy dating behaviors. Areas needing improvement included low knowledge, unfavorable attitudes, poor normative beliefs, and low self-efficacy regarding condom use. Caregiver strengths included positive attitudes, normative beliefs, and self-efficacy for sex communication; positive attitudes and self-efficacy for condom use; and low acceptance of couple violence. Areas needing improvement included low levels of actual communication about sex and low knowledge about effective communication strategies and condom use. The current study highlights the value of assessing baseline characteristics of LHAs prior to intervention implementation, as it enables a better understanding of the key characteristics necessary for planning and implementing interventions, as well as engaging in targeted training activities.  相似文献

Two hundred and seventy-seven drug using adults were interviewed regarding details of their most recent sexual encounter. Demographic, attitudinal, and context variables were associated with condom use and non-use. Greater perceived risk of STDs/HIV and positive attitudes toward condoms' effect on sexual pleasure were associated with greater likelihood of reporting condom use. Common reasons for not using condoms included lower perceived risk of contracting HIV/STDs, negative attitudes toward condoms' effect on pleasure, and lack of condom availability. Tailoring messages to modifiable perceptions of risk and condom attitudes may be useful in reducing sexual risk among drug-using individuals.  相似文献

Women account for 30% of all AIDS cases reported to the Health Ministry in Portugal and most infections are acquired through unprotected heterosexual sex with infected partners. This study analyzed socio-demographic and psychosocial predictors of consistent condom use and the role of education as a moderator variable among Portuguese women attending family planning clinics. A cross-sectional study using interviewer-administered fully structured questionnaires was conducted among 767 sexually active women (ages 18–65). Logistic regression analyses were used to explore the association between consistent condom use and the predictor variables. Overall, 78.7% of the women were inconsistent condom users. The results showed that consistent condom use was predicted by marital status (being not married), having greater perceptions of condom negotiation self-efficacy, having preparatory safer sexual behaviors, and not using condoms only when practicing abstinence. Living with a partner and having lack of risk perception significantly predicted inconsistent condom use. Less educated women were less likely to use condoms even when they perceive being at risk. The full model explained 53% of the variance in consistent condom use. This study emphasizes the need for implementing effective prevention interventions in this population showing the importance of taking education into consideration.  相似文献

Free condoms provided by the government are often not used by Botswana Defence Force (BDF) personnel due to a perceived unpleasant scent and unattractive wrapper. Formative work with the BDF found that scented condoms and military-inspired (camouflage) wrapper graphics were appealing to personnel. A non-randomized intervention study was implemented to determine whether condom wrapper graphics and scent improved condom use in the BDF. Four military sites were selected for participation. Two sites in the south received the intervention condom wrapped in a generic wrapper and two sites in the north received the intervention condom wrapped in a military-inspired wrapper; intervention condoms were either scented or unscented. Two hundred and eleven male soldiers who ever had sex, aged 18–30 years, and stationed at one of the selected sites consented to participate. Sexual activity and condom use were measured pre- and post-intervention using sexual behavior diaries. A condom use rate (CUR; frequency of protected sex divided by the total frequency of sex) was computed for each participant. Mean CURs significantly increased over time (85.7% baseline vs. 94.5% post-intervention). Adjusted odds of condom use over time were higher among participants who received the intervention condom packaged in the military wrapper compared with the generic wrapper. Adjusted odds of condom use were also higher for participants who reported using scented vs. unscented condoms. Providing scented condoms and condoms packaged in a miltiary-inspired wrapper may help increase condom use and reduce HIV infection among military personnel.  相似文献

This study used a stage-based approach to understand condom use behavior in a representative sample of 309 sexually active homeless youth recruited from shelters, drop-in centers, and street sites in Los Angeles County. Focusing on the youth's most recent sexual event, the three stages of condom use examined were: (1) whether the partners decided prior to the event about using condoms; (2) whether a condom was available at the event; and (3) whether a condom was used at the event. Logistic regression analysis was used to identify attitudinal, relationship, and contextual correlates of each of these three stages. Deciding ahead of time about condom use was associated with being Hispanic, level of education, condom attitudes, and various relationship characteristics (e.g., partner type, monogamy, relationship abuse), with the nature of these associations varying depending on the type of decision (i.e., deciding to use, deciding to not use). Condom availability was more likely to be reported by males, if the event was described as being special in some way, or if the event lacked privacy. Condom use was more likely among youth with more positive condom attitudes and among youth who decide ahead of time to use a condom, but less likely among those in monogamous relationships or when hard drugs were used prior to sex. Whether sexual intercourse is protected or unprotected is the end result of a series of decisions and actions by sexual partners. Results from this study illustrate how condom use can be better understood by unpacking the stages and identifying influential factors at each stage. Each stage may, in and of itself, be an important target for intervention with homeless youth.  相似文献

This study examined condom attitudes, preferences, barriers, and use among a sample of 550 injection drug using clients of syringe exchange programs in California. In multivariate analyses, positive attitudes toward condoms were significantly associated with consistent condom use for vaginal, anal, and oral sex in the past six months, beyond the effects of confounding socio-demographic and HIV risk variables. Participants commonly cited partner-related barriers to condom use, such as reluctance to use condoms with steady partners (34%). Almost a quarter of the sample cited dislike of condoms (e.g., because of pleasure reduction). In addition, a third of respondents stated specific preferences regarding condom brands, sensitivity, sizes, and textures. Interventions that increase awareness about positive aspects of condom use and sexual risk from steady partners may be successful in increasing condom use among injection drug users.  相似文献

Traditionally, researchers have focused HIV/AIDS prevention efforts on increasing condom use, yet few researchers have assessed condom use skills. Because incorrect condom use may lead to condom failure, promoting condom use without ensuring participants have the skills necessary for correct condom use may lead to increased risk of exposure. This study compared the effects of two condom use courses on condom use skills. These courses were administered as part of a HIV/AIDS educational program for college students. Participants in the treatment groups (n=179) attended either a limited, 1-Session, or extensive, 3-Session, condom use course, and an additional 108 participants served as a Control Group. Condom use skills increased among participants in both treatment groups; however, the greatest improvement was among those in the 3-Session Group. This finding supports use of the extensive, 3-Session course as a more effective means for improving condom use skills.  相似文献

The relationship between neighborhood social dynamics and adolescent sexual behavior has not been well explored. We conducted a cross-sectional survey with 343 adolescents recruited from two health clinics in Baltimore. Multivariate logistic regression was utilized to assess the influence of perceived neighborhood social cohesion and collective monitoring of youth on condom use at last sex, controlling for family and individual factors. Condom use was significantly higher among participants who perceived their neighborhoods as high, 54.7%, versus low, 40.4%, in social cohesion. Neighborhood cohesion was significantly associated with condom use in multivariate analyses, as was parental communication, family structure, and gender. No association between perceived neighborhood collective monitoring of youth and condom use was found. We conclude that perceived neighborhood social cohesion is positively associated with condom use among adolescents vulnerable to HIV/STI and should be encouraged in the context of community-based prevention efforts.  相似文献

ABSTRACT

Geosocial-networking smartphone applications represent an increasingly common virtual context in which men who have sex with men (MSM) meet their sexual partners. The purpose of the present study is to evaluate community-level sexual behavior norms and their associations with condom use among MSM in Atlanta, Georgia, recruited from a popular smartphone application (n?=?92). Engagement in condomless anal intercourse was more common among participants who agreed that, among MSM in their community, (a) it is difficult to negotiate condom use in partnerships where condomless sex has already occurred and (b) suggesting condom use implies one distrusts their partner. These norms may represent barriers to increasing condom use.  相似文献

Background: There is a need to understand resiliency factors which can be used to inform and design interventions to prevent externalizing problems, substance use, and depressive symptoms among American Indian (AI) youth. Objectives: The present study examined the role of self-efficacy in externalizing problems, alcohol use, and depressive symptoms among AI youth from the North American plains. Methods: Participants for this study included 146 (53 boys and 93 girls) adolescents, with an age range of 13–18 (M?=?14.5) years of age. Results: High self-efficacy for resisting negative peer influences predicted both lower rates of alcohol use and fewer externalizing behaviors. Furthermore, higher levels of both academic and social self-efficacy predicted fewer depressive symptoms. The hypothesis that academic self-efficacy would predict depressive symptoms was not supported. Conclusion: As expected, the best-fitting path model showed self-efficacy for resisting negative peer influences predicting both alcohol use and externalizing problems, and social self-efficacy (as well as being female) predicting depressive symptoms among AI youth. Therefore, this study supports the importance of self-efficacy beliefs for alcohol use and externalizing problems, as well as depressive symptoms, among AI youth.  相似文献

Abstract

HIV prevention for women with substance use disorders is a public health priority. To identify characteristics associated with sexual risk among women in outpatient substance abuse treatment we categorized 809 screened women into three groups: (1) sexually inactive, (2) sexually active with consistent condom use, and (3) sexually active with inconsistent condom use. Multinomial logistic regression analyses were used to examine demographics, substance use and treatment characteristics, and regional HIV seroprevalence as predictors of sexual risk behavior. Younger age and attending psychosocial (PS) treatment were significantly associated with being at higher HIV risk. HIV prevention should be tailored to address HIV risk in younger women in PS treatment.  相似文献

ABSTRACT

Evidence shows that low condom use is the norm in relationships between female sex workers (FSWs) and their regular partners. We investigated the timing of sexual initiation in a relationship with a regular partner as a critical factor in determining condom use. Three rounds of Integrated Behavioral and Biological Assessment (IBBA) surveys were used to derive whether regular partner relationships began before or after sex work initiation. Of the 7,015 FSWs surveyed, 33% started an intimate partner relationship before sex work initiation, 27% after beginning sex work, and the remaining 40% did not have a regular partner. Condom use was significantly higher in a FSW’s relationship after sex work initiation (p?<?0.01), compared to a relationship with a regular partner before sex work. Programmatically, more efforts and resources are necessary toward promoting condom use among FSWs who have regular partner relationships before their initiation of sex work.  相似文献

Both drug injection and sexual transmission are the primary drivers of the HIV epidemic in China. This study investigated the prevalence and associated factors of intention of consistent condom use during sexual intercourse with female regular partners (RP), non-regular partners (NRP) and sex workers (FSW) among male people who inject drugs (PWID)in China. A total of 529 male non-institutionalized PWID aged 18–45 years with negative/unknown HIV status were recruited by multiple methods in Dazhou and Hengyang, China. The constructs of the pre-intention phase of the Health Action Process Approach (HAPA) Model, including partner-specific HIV risk perception, condom use positive outcome expectancies, condom use negative outcome expectancies, and self-efficacy of condom use, were assessed. The prevalence of behavioral intention of consistent condom use with RP, NRP, and FSW was 32.1%, 49.1%, and 63.6%, respectively. In multivariate stepwise analysis, conditional risk perception of HIV transmission via unprotected sex with RP/NRP/FSW was associated with intention of consistent condom use with these types of female sex partners (multivariate odds ratio (ORm)?=?3.25–7.06). Condom use negative outcome expectancies were associated with intention of consistent condom use with RP and NRP (ORm?=?0.30–0.46), while condom use self-efficacy was associated with intention of consistent condom use with RP and FSW in the next six months (ORm?=?2.24–3.81). Male PWID are at high risk of HIV transmission through sexual behaviors. The pre-intention phase of the HAPA model may be applied to plan interventions to increase behavioral intention of consistent condom use with various types of female partners. Such interventions are warranted.  相似文献
