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. 相似文献

PURPOSE: To examine the sexual behaviors and related risk factors for sexually transmitted diseases and HIV among young adults who seek sex partners on the Internet.METHODS: Study staff recruited participants in online chat rooms, bulletin boards, and other online venues. A total of 4507 participants responded to a 68-item, self-administered, online survey of Internet sex-seeking practices. The survey solicited information on sexual behavior with partners found on the Internet; in addition, a parallel set of questions addressed sexual behaviors with partners found off the Internet. Of the respondents, 1234 (27.4%) were 18-24 years old. Of the young adults, 61% were male and 75% were white. Responses from young adults were compared to those received from older adults. In addition, responses from young adults who seek sex partners online were compared to responses from young adults who do not seek sex partners online. Analyses, including logistic regression, Chi-square tests, Student's t-tests, and analyses of variance, focused on the difference between young and older adults, as well as the differences in sexual behavior with partners located online and offline. RESULTS: Young adults who seek sex on the Internet report substantially different sexual behavior patterns than young adults who do not seek sex on the Internet. Young adults with online partners reported sexual behaviors similar to older respondents who used the Internet to find sex partners; however, older respondents were more likely than young adults to have been tested for sexually transmitted diseases and HIV. CONCLUSIONS: Young adults who seek sex partners online may be at significantly greater risk for sexually transmitted diseases than their peers who do not seek sex partners online. These data point to an urgent need for online sexual health promotion. 相似文献

ObjectivesTo determine the seroprevalence of HIV among a representative sample of drug-using adults in a rural area. Also, to determine whether young drug-using adults in a rural area engage in greater levels of sexual risk behavior than their older counterparts.MethodsCross-sectional study of 503 adult drug users. Rapid tests for antibodies to HIV were used, and self-reported data were collected via computer.ResultsNone of the participants tested positive for antibodies to HIV. In bivariate tests, only 2 differences were observed between young and older participants. Young males were more likely to engage in unprotected vaginal sex (P = .018) and young females were more likely to engage in unprotected sex with persons injecting drugs (P = .016). In controlled multivariate analyses, age had a modest but significant association with an 8-item index of sexual risk behavior (β = ?0.15) and a reduced 6-item index of risk (β = ?0.18).ConclusionDespite a fairly dense and interactive sexual network and relatively high-levels of sexual risk behaviors, this rural population has not yet been affected by the HIV epidemic. In the event an outbreak of HIV in this population the observed levels of sexual behavior suggest that rapid sexual transmission could occur among drug-using populations and may include persons of all ages. 相似文献

Early onset of substance use among adolescents has been found to be associated with later risky sexual behaviors. This study examined long-term follow-up data from a large randomized school-based drug prevention trial to (1) investigate the long-term impact of the prevention program on drug use and sexual behaviors that put one at elevated risk for HIV infection; and (2) use growth modeling procedures to examine potential mechanisms of intervention effects. Self-report survey data were collected from students in the 7th grade, prior to the intervention in 1985, and in grades 8, 9, 10, and 12. Participants in the intervention condition received a 30-session drug prevention program in 7th through 9th grades. Follow-up surveys were completed by 2042 young adults (mean age = 24) in 1998. As young adults, participants were considered to be engaging in high-risk behavior for HIV infection if they reported having multiple sex partners, having intercourse when drunk or very high, and recent high-risk substance use. The intervention had a direct protective effect on HIV risk behavior in the overall sample in young adulthood. Furthermore, among participants receiving 60% or more of the prevention program, analyses showed that the intervention significantly reduced growth in alcohol and marijuana intoxication over the course of adolescence, which in turn was associated with a reduction in later HIV risk behavior. The behavioral effects of competence-enhancement drug prevention programs can extend to risk behaviors including those that put one at risk for HIV infection. 相似文献

CONTEXT: Sexual and substance use behaviors covary in adolescence. Prevalence of HIV and other sexually transmitted diseases (STDs) differs according to race and gender, yet few studies have systematically investigated risk behavior patterns by subgroup, particularly with nationally representative data. METHODS: A priori considerations and K-means cluster analysis were used to group 13,998 non-Hispanic black and white participants in the National Longitudinal Study of Adolescent Health, Wave 1, according to self-reported substance use and sexual behavior. Multinomial logit analyses examined racial and gender differences by cluster. RESULTS: Among 16 clusters, the two defined by the lowest risk behaviors (sexual abstinence and little or no substance use) comprised 47% of adolescents; fewer than 1% in these groups reported ever having received an STD diagnosis. The next largest cluster-characterized by sexual activity (on average, with one lifetime partner) and infrequent substance use-contained 15% of participants but nearly one-third of adolescent with STDs. Blacks were more likely than whites to be in this group. Black males also were more likely than white males to be in three small clusters characterized by high-risk sexual behaviors (i.e., having had sex with a male or with at least 14 partners, or for drugs or money). Black females generally were the least likely to be in high-risk behavior clusters but the most likely to report STDs. CONCLUSIONS: Adolescents' risk behavior patterns vary by race and gender, and do not necessarily correlate with their STD prevalence. Further investigation of adolescents' partners and sexual networks is needed. 相似文献

Most prior studies examining drug use among men who have sex with men (MSM) have been cross-sectional or retrospective and have not determined whether periods of increased drug use are associated with high-risk sexual behavior at the individual level. In this article, we describe patterns of use of methamphetamines, poppers, and sniffed cocaine and sexual risk behavior among 736 San Francisco MSM enrolled in the EXPLORE study and followed for up to 48 months. In longitudinal analysis, use of methamphetamines, poppers, and sniffed cocaine declined during follow-up. However, compared with older participants, younger participants were more likely to increase their drug use over time. Results of conditional logistic regression demonstrated that high-risk sexual behavior was more common during reporting periods characterized by increased methamphetamine, poppers, or sniffed cocaine use. This within-person analysis found that compared with periods of no drug use, periods of both light drug use (less than weekly use of drugs) and heavier drug use (at least weekly use of at least one drug) were significantly associated with increased risk of engaging in uprotected anal sex with an HIV-positive or unknown-status partner. These results suggest that even intermittent, recreational use of these drugs may lead to high-risk sexual behavior, and that, to reduce and prevent risks of HIV, no level of use of these drugs should be considered “safe.” HIV prevention interventions should target MSM who report either light or heavy use of methamphetamines, poppers, and sniffed cocaine. 相似文献

There is evidence that risks for HIV and sexually transmitted infections among adolescent females are higher for those with
older male sexual partners. Yet, little empirical research has been conducted with male adolescents who engage in sexual activity
with older men. In this article, we summarize in a number of ways the range of sexual activity reported by an ethnically diverse
sample of 200 gay and bisexual male youth (15–22 years old) in Chicago and Miami. A general pattern of progression from oral
sex with men to both receptive and insertive anal sex with men appeared to characterize the sample during their adolescence.
Further, there appeared to be a high degree of “versatile” positioning among the sexually active gay and bisexual young men,
in both age-discrepant and age-concordant dyads. Risk analysis revealed having primarily age-concordant partners to be a significant
predictor of sexual risk behavior. HIV risk among young gay and bisexual men engaging in sexual activity with older men may
occur not only within a distinct biological context from their heterosexual counterparts, but also in a social context that
may not as rigidly bound to traditional assumptions about age, gender, and power. The significant associations among participants
with partners who were the same age and the risk behavior measures in this analysis have implications for HIV prevention efforts. 相似文献

15-month followup of women methadone patients taught skills to reduce heterosexual HIV transmission.
Heterosexual contact with intravenous drug users accounts for a growing proportion of cases of acquired immunodeficiency syndrome (AIDS) among women. In an earlier study designed to reduce sexual risk behavior, the authors randomly assigned 91 methadone maintained women to information-only or skills-building conditions. Modest outcomes favored participants in the skills-building group. In this 15-month followup of 62 remaining study participants, skills-training group members were more likely than controls to use condoms. In comparison with controls, members in the skills-building group felt more comfortable talking about safe sex, perceived themselves as more able to reduce their exposure to AIDS, but were more likely to attribute AIDS risk to luck. No associations were found between group condition and number of sexual partners or frequency of buying and carrying condoms. Some gains associated with a group intervention tended to be maintained over time, indicating that preventive interventions composed of multiple sessions and conducted in treatment settings may have promise as useful strategies to prevent human immunodeficiency virus (HIV) infection. Nevertheless, decay was evident in other domains, suggesting that prevention specialists should consider booster sessions or other means of maintaining changes in risk behavior. 相似文献

PurposeTo identify correlates of sexual risk variations among African-American adolescents, and to examine the influence of prior sexual experience on response to a HIV risk-reduction intervention.MethodsEight hundred seventeen African-American youth aged 13 to 16 years living in and around urban public housing in Baltimore were recruited to participate in a HIV risk-reduction intervention targeting multiple risk behaviors. An instrument designed to measure three levels of sexual risk (“abstinent,” “protected sex” [having sex with a condom], and “unprotected sex” [having sex without a condom]) was administered at baseline, 6 months and 12 months postintervention. Multiple regression analyses were conducted to identify predictors of the degree of sexual risk using longitudinal data. Repeated measure analyses were conducted to assess behavioral changes over time among the three groups.ResultsData confirmed the co-variation of sexual risk behavior and other problem behaviors among adolescents, cross-sectionally and longitudinally. After exposure to an 8-session risk-reduction intervention, youth engaging in the highest degree of sexual risk demonstrated the greatest reduction in both sexual risk and other risks. These improvements were seen at both 6 months and 12 months postintervention. Youth who were abstinent at baseline maintained the lowest levels in risk involvement throughout the study period when compared with sexually active youth. However, abstinent youth risk involvement significantly increased at 6 months and 12 months after baseline. Youth engaging in protected sex at baseline demonstrated a significant increase in non-condom use and a significant decrease in multiple risk involvement over time.ConclusionsResults support HIV risk-reduction intervention efforts that target multiple risk behaviors. Response of adolescents to the intervention is directly related to the sexual risk behavior at baseline. These data may suggest that the response to risk behavior intervention depends in part on the risk behavior profile of the population to which it is being applied. 相似文献

Rates of HIV/AIDS and depression in women are significant public health concerns. The current meta-analysis tested the hypothesis that depression levels moderate change in sexual risk behavior in women participating in HIV prevention interventions. Features of the interventions were also explored as possible factors in decreasing levels of depression and sexual risk behavior. Included were HIV primary prevention interventions that measured sexual risk behavior and depression at baseline and follow-up and reported separate results for women. Ten studies (fourteen intervention groups and ten control groups; N = 4,195 women) met the inclusion criteria. The majority of participants were African American; mean age was 28-years old. Both depression and sexual risk behavior decreased significantly in treatment and control groups from baseline to follow-up. Sexual risk decreased more to the extent that interventions sampled (a) participants with higher baseline levels of depression, (b) older women, (c) Hispanics/Latinas, and/or (d) members of risk groups (e.g., drug users, homeless). Interventions that included (e) condom provision, (f) information about condoms, and/or (g) HIV counseling and testing were also more successful in decreasing sexual risk. Finally (h), interventions were more likely to reduce sexual risk behavior when they decreased depression to a large extent relative to baseline levels. Interventions were more likely to decrease depression when they (a) had samples of only women, (b) targeted risk groups, and/or (c) provided self-management and coping skills. Reducing depression appears to play a role in decreasing sexual risk behavior, suggesting that interventions should actively address depression. 相似文献

Thailand is in the midst of a social and sexual transition that is affecting gender roles, sexual behavior, and, hence, risk for HIV. The continuation of past traditions, such as men having sex with commercial sex workers, coupled with an increasing acceptance of noncommercial premarital sex among young people, is fueling the AIDS epidemic. To examine young people's potential risk for HIV, the author investigated their perspectives on sexual behavior and sexual networking, the continued acceptance of premarital sex with commercial sex workers, and perception of risk for HIV in Chiang Mai. This study suggests that a changing social environment and the response to the AIDS epidemic have resulted in new patterns of sexual behavior that might trigger the dissemination of HIV into a broader network. 相似文献

CONTEXT: Over the past several years, there have been sharp increases in the prevalence of HIV and other sexually transmitted diseases (STDs) among young people in Russia. Very little is known about Russian adolescents' behaviors and attitudes that might influence their risk of acquiring these infections. METHODS: A 1995 survey of 533 students aged 15-17 attending eight St Petersburg high schools assessed their sexual risk practices, AIDS-specific attitudes and beliefs, sexual relationship patterns and preferences, and social characteristics. RESULTS: Overall, 39% of students were sexually experienced, and these young people had had, on average, 3.4 sexual partners. Only 29% of sexually experienced students said they consistently used condoms, and 29% said they never did. Unprotected vaginal intercourse was the predominant and preferred sexual practice; it also was the practice that most often occurred with students' last sexual partner. In all, 28% of students defined "safer sex" as condom use. Many young people believed that AIDS is a threat only to members of particular "risk groups"; relatively few believed that they could get AIDS (17%) or said that AIDS information had influenced their sexual behavior (29% of those who were sexually experienced). Females were more likely than males to prefer having an exclusive partner, and males were more likely to prefer having casual partners. CONCLUSIONS: Educational and behavioral interventions are urgently needed to help young people in Russia avoid HIV and other STDs. Risk and social characteristics identified in this study can help to guide the development and tailoring of risk reduction interventions. 相似文献

We explored the feasibility of engaging young black men in a 12-week text messaging programme about HIV prevention. There were two non-randomized groups of 30 young men each. The participants were aged 16-20 years, self-identifying as black or African-American, sexually active, who owned a mobile phone and lived in Philadelphia. They received three text messages per week for 12 weeks. People in the intervention group received text messages about HIV prevention, while those in the control group received text messages about nutrition. The intervention participants showed trends in increased monogamy at follow-up compared to controls. Awareness of sexual health was significantly higher in the intervention group. Condom norms were significantly higher for the control group. There were no differences in the proportion of protected sex acts. The participants embraced the project, and were enrolled and retained in numbers that suggest such an intervention is worth examining for efficacy. 相似文献

We asked 298 heterosexual Canadian university students about their definitions of the terms abstinence and having sex. For both terms, students were provided with a list of 17 sexual behaviors and indicated whether they would include each in
their definition. The majority of both male and female students included activities that did not involve genital stimulation
in their definition of sexual abstinence and did not include these activities in their definition of having sex. Conversely,
most students did not include bidirectional sexual stimulation (penile–vaginal intercourse or penile–anal intercourse) in
their definitions of sexual abstinence but did include them in their definitions of having sex. Students were quite mixed
in whether activities involving unidirectional genital stimulation (e.g., oral sex, genital fondling) constituted abstinence,
having sex, or neither abstinence nor having sex. However, they were more likely to see these behaviors as abstinent than
as having sex. Students were more likely to rate a behavior as abstinence if orgasm did not occur. A canonical correlation
analysis was used to examine the patterns of association between a number of predictors and inclusions of behaviors involving
no genital stimulation, unidirectional stimulation, and bidirectional genital stimulation in abstinence definitions. The results
indicated that male participants who were more involved with their religion and sexually conservative, less sexually experienced,
and who had not received sexual health education at home were more likely to define bidirectional genital stimulation and
less likely to define no genital stimulation and unidirectional sexual stimulation as sexual abstinence. The research and
health promotion implications of these results are discussed. 相似文献

BACKGROUND: Research on the long-term persistence of effects of interventions aimed at smoking cessation is limited. This paper examined the quitting behavior of individuals who were randomized to a smoking cessation intervention (SI) or to usual care (UC), at a point approximately 11 years later. METHODS: The initial sample consisted of 5,887 adult smokers in 10 clinics who had evidence of airways obstruction. Two-thirds of the original participants were offered an intensive 12-week smoking cessation intervention. Of these, 4,517 were enrolled in the long-term follow-up study. RESULTS: Randomized group assignment was a strong predictor of smoking behavior after 11 years, in that 21.9% of SI participants and only 6.0% of UC participants maintained abstinence throughout the interval. Logistic regressions identified covariates associated with abstinence. A higher proportion of abstinence was observed in participants that had been assigned to SI (OR = 4.45), were older (OR = 1.11, increment 5 years), had more years of education (OR = 1.05), and fewer cigarettes/day at baseline (OR = 0.90, increment 10 cigarettes). CONCLUSIONS: Smokers exposed to an aggressive smoking intervention program and who sustain abstinence for a five-year period are very likely to still be abstinent after 11 years. 相似文献

Young men who have sex with men (YMSM) in the United States are experiencing an alarming increase in HIV incidence. Recent evidence suggests that the majority of new HIV infections in YMSM occur in the context of serious relationships, which underscores the importance of examining predictors of sexual risk behavior in the context of sexual partnerships, including relationship type, sexual partner characteristics, and relationship dynamics. The current study aimed to evaluate relationship and sexual partnership influences on sexual risk behavior in YMSM, including differentiating between multiple sexual risk variables (i.e., any unprotected anal or vaginal intercourse, unprotected insertive anal or vaginal intercourse, and unprotected receptive anal intercourse). More serious/familiar partnerships were associated with more sexual risk across all three risk variables, while wanting a relationship to last was protective against risk across all three risk variables. Some variables were differentially linked to unprotected insertive sex (partner gender) or unprotected receptive sex (partner age, partner race, believing a partner was having sex with others, and partners repeated across waves). Sexual risk behavior in YMSM is inconsistent across sexual partnerships and appears to be determined in no small part by sexual partner characteristics, relationship dynamics, and sexual role (i.e., insertive or receptive partner). These influences are critical in understanding sexual risk in YMSM and provide important targets for intervention. 相似文献

Adolescents may come from family settings that heighten their vulnerability to early sexual initiation, promiscuity and sexual exploitation. Using qualitative data, we illustrated how early life and family circumstances including neglectful or dysfunctional parenting, sexual abuse, and unstable housing placed young women on a risk trajectory for HIV infection. Five representative cases from a sample of 26 adolescent and young adult HIV-infected females (ages 16-24) who participated in a study about the disease-related adaptive challenges they faced are discussed. Study participants were recruited from five New York City adolescent HIV clinics that provided comprehensive specialty medical and ancillary social services to adolescents and young adults with the disease. The findings revealed that these young women’s unmet need for love, protection, and feeling valued left them vulnerable to exploitive relationships with men who were often significantly older and resulted in their HIV infection. 相似文献

Male-to-female transgender persons are thought to be “vectors” for HIV/STI transmission, yet little quantitative information
exists about the risk behavior of their male sexual partners who may serve as a “bridge” for HIV transmission into the general
population. As part of an online survey examining the sexual risk behavior of Latino men who have sex with men (N = 1,026), we identified 44 (4%) participants who reported having had sex with a transgender partner. Compared with a randomly
selected sub-sample of 200 men who did not report sex with a transgender person, sexual partners of transgender persons were
almost three times more likely to have had unprotected sexual intercourse in the last three months. In addition, men who had
sex with transgender persons were more likely to be HIV-positive; married, separated, or divorced; identify as bisexual or
straight; have sex with women; and live in rural or small town communities. Regression analysis revealed that community size,
sexual compulsivity, and having had a transgender partner were independent predictors of unprotected sex. Among Latino men
who have sex with men, men with a history of sex with a transgender person appear more likely to be sexually compulsive and
at greater risk for HIV and other sexually transmitted infections. These men may, therefore, also serve as a “bridge” for
HIV transmission to (as opposed to from) the transgender population. 相似文献

HIV and STD prevention is an essential component of public health initiatives in countries throughout Central and Eastern Europe. Liberalization in sexual values, declining age at first sex, higher levels of sexual activity, and inconsistent condom use have been well-documented among young people in the region following the political, economic, and cultural transitions after the end of the state socialism era. Less well-understood are the reasons for high-risk sexual behavior and psychosocial factors that must be addressed in the development of effective HIV/STD prevention programs. This study recruited members of 12 high-risk social networks of young adult men and women (n= 66 participants) in two cities, St. Petersburg, Russia, and Budapest, Hungary. In-depth focus groups were conducted with all members of each network, and qualitatively analyzed to examine factors surrounding high-risk sexual behavior. Main themes that emerged were that STDs are less known and less feared than AIDS, HIV risk factors were relatively well known among young adults in both countries but vulnerability is perceived differently, pregnancy prevention is a more immediate concern than protection from HIV or STDs, condom use declines quickly following first sex with a new partner, reintroducing condom use in a relationship is very difficult, and young adults report many barriers to condom use including those related to alcohol or other substance use. HIV/STD prevention programs are needed that extend beyond risk education alone and that also address critical psychological, social, and relationship factors related to sexual risk behavior. 相似文献
