BackgroundFinding casual sex partners on the internet has been considered a huge challenge for HIV transmission among men who have sex with men (MSM) in China.ObjectiveThis study aimed to identify the characteristics and risk factors of finding causal sex partners on the internet among MSM in Zhejiang Province, China.MethodsThis was a cross-sectional study. Participants were enrolled by 4 community-based organizations (CBOs) and 10 Voluntary Counselling and Testing (VCT) clinics through advertisements in bathrooms, bars, and gay hook-up apps from June to December 2018. A CBO- or physician-assisted survey was conducted to collected information on finding casual sex partners, perceived HIV infection, and HIV risk behaviors.ResultsAmong 767 participants, 310 (40.4%) reported finding causal sex partners on the internet. Factors associated with finding casual sex partners on the internet included watching pornographic videos on the internet more than once a week (adjusted odds ratio [aOR]=1.881, 95% CI 1.201-2.948), discussing “hooking-up online” with friends (aOR=4.018, 95% CI 2.910-5.548), and perceiving that the likelihood of HIV infection among casual sex partners sought on the internet was “medium” (aOR=2.034, 95% CI 1.441-2.873) or “low” (aOR=2.548, 95% CI 1.524-4.259). Among the participants who reported finding casual sex partners on the internet, 30.2% (91/310) reported having unprotected sex with casual sex partners encountered on the internet in the past 6 months. On multivariate logistic regression analyses, knowing the HIV infection status of casual sex partners sought on the internet was significantly associated with performing inserted intercourse (aOR=1.907, 95% CI 1.100-3.306) and a decreased risk of inconsistent condom use (aOR=0.327, 95% CI 0.167-0.642).ConclusionsWeb-based casual sexual behavior is becoming more prevalent, and the rate of unprotected sex among MSM in Zhejiang Province is high. Future HIV prevention approaches should emphasize the importance for MSM to proactively determine the HIV infection status of potential casual sex partners sought on the internet. 相似文献

Over the past three decades, most research on adolescent sexual behavior has focused on vaginal intercourse and related behaviors,
including contraception and unintended pregnancy. In this study, we describe the prevalence and correlates of vaginal, oral,
and anal sex in an epidemiologically defined population in Baltimore, Maryland. Young adults (ages 18–24), who had been enrolled
in a behavioral intervention trial during elementary school, were interviewed by telephone between 1998 and 2002 to assess
their sexual behavior. Of 1679 respondents interviewed, 70.8% were Black and 55% were women. Overall, 93% of the young adults
reported vaginal intercourse, 78% reported receiving oral sex, 57% reported performing oral sex, and 10% reported receptive
anal intercourse. Among men, 27% reported insertive anal intercourse. Blacks initiated vaginal intercourse at an earlier age
than Whites; White women performed oral sex earlier than Black women. Significant interactions were observed between age of
first vaginal partner and both gender and race/ethnicity. Blacks with older partners initiated sex at an earlier age than
both Blacks with a partner the same age or younger and Whites. We also observed a relationship between older female sex partners
and earlier vaginal sex initiation among men. We conclude that older sex partners play an important role in sexual initiation
among young adults. In light of the rates of oral and anal sex, sexual education and intervention programs should address
the risk for unintended consequences of these behaviors. 相似文献

Undergraduate students were asked about their use of condoms and their attempts to dissuade sexual partners from the couple using condoms during sexual intercourse. Nearly 14% of women and nearly 17% of men who had engaged in sexual intercourse admitted to having actively tried to dissuade a partner from the couple using condoms. Thirty percent of the men and 41% of the women said that a sexual partner had tried to dissuade them. Attempts to dissuade partners from the couple using condoms were most common among students who reported having 10 or more lifetime sexual partners. For both men and women, the most frequently employed categories of verbal strategies were (1) sex feels better without a condom, (2) will not get pregnant, and (3) will not get a sexually transmitted disease. These three categories accounted for about three-fourths of the lines used. Avoidance of condoms because of a perceived decrease in physical pleasure poses a particular problem for sex and health educators. 相似文献

Individual differences are increasingly considered important in the relationship between work-family balance and health. The present study examined the role of autonomy-connectedness in positive and negative work-family interaction and family-work interaction. We also investigated the relationship of work-family interaction and family-work interaction with positive and negative affect, coping patterns, and demographic characteristics. All variables under study were measured with questionnaires in a Dutch sample of 205 respondents. As expected, the individual difference factors were substantially associated with work-family interaction and family-work interaction; together they accounted for 10 to 39% of their variance. In particular, negative affect and the autonomy-connectedness components Sensitivity to others and Capacity for managing new situations appeared to be strongly related to work-family interactions. Health implications of the findings are discussed and recommendations for further research are presented. 相似文献

Heterosexual partnerships involving the trade of money or goods for sex are a well-described HIV risk factor in Africa and
Southeast Asia, but less research has been conducted on exchange partnerships and their impact on HIV infection in the United
States. In our study, men and women were recruited from high-risk risk neighborhoods in New York City through respondent-driven
sampling in 2006–2007. We examined the factors associated with having an exchange partner in the past year, the relationship
between exchange partnerships and HIV infection, and the risk characteristics of those with exchange partners by the directionality
of payment. Overall, 28% of men and 41% of women had a past-year exchange partner. For men, factors independently associated
with exchange partnerships were older age, more total sexual partners, male partners, and frequent non-injection drug use.
For women, factors were homelessness, more total sexual partners, more unprotected sex partners, and frequent non-injection
drug use. Exchange partnerships were associated with HIV infection for both men and women, although the relationships were
substantially confounded by other behavioral risks. Those who both bought and sold sex exhibited the highest levels of risk
with their exchange and non-exchange partners. Exchange partnerships may be an HIV risk both directly and indirectly, given
the overlap of this phenomenon with other risk factors that occur with both exchange and non-exchange partners. 相似文献

The role of genetic and environmental influences on age of initiation of first sexual relations and engaging in sexual activity with multiple partners (10 or more partners in 1 year) was investigated in male twins (N = 6,744) from the Vietnam Era Twin Registry. Individual differences in both types of sexual behaviors were heritable, but only age of onset of sexual relations was significantly influenced by the environment shared by the twins. There was a moderate negative correlation between age of initiation of sexual relations and the multiple partners variable; initiating sexual relations earlier was associated with a higher probability of having multiple partners. The additive genetic influence on age of initiation also influenced the multiple partners variable. The substantial unique environmental influences on each variable were uncorrelated with each other. The data suggest that the observed association between age of initiation of sexual relations and having multiple partners is due to genetic influences common to both behaviors. 相似文献

This study compared sexual behavior of gay and bisexual men (N = 551) while at their primary residence to their behavior while vacationing at a gay resort community. Participants reported behavior for the days they spent in the resort and for their last 60 days in their home residences. Overall, 11 times more non-main partners were reported for unprotected anal intercourse (UAI) per day while in the resort as for the “at home” period. Regression analysis identified negative attitudes toward condoms, less concern about AIDS, and daily number of non-main, male partners at home with whom UAI occurred as significant predictors of the daily number of non-main male partners with whom holidaymakers engaged in UAI while in the resort area. The results suggest that sexual risk taking by men who have sex with men (MSM) while on holiday may be elevated over that at home and that prevention efforts need to be promoted in gay resorts. Behavioral surveillance research would be helpful in better characterizing the current social contexts of sexual risk taking by MSM. Theory-based studies of the nature of risk-taking and sexual decision-making on “gay holiday” could inform the development of empirically proven and conceptually grounded interventions. 相似文献

Arousal Loss Related to Safer Sex and Risk of Pregnancy: Implications for Women's and Men's Sexual Health 总被引:1,自引:0,他引:1
ByJenny A. Higgins Amanda E. Tanner Erick Janssen 《Perspectives on sexual and reproductive health》2009,41(3):150-157
CONTEXT: Few studies have examined arousal loss associated with safer-sex practices or the perceived risk of unintended pregnancy, let alone its associations with sexual risk practices.
METHODS: An Internet survey conducted in 2004–2006 among 2,399 men and 3,210 women asked respondents about arousal loss related to the use of condoms or other safer-sex products and perceived unintended pregnancy risk. Regression analyses gauged associations between arousal profiles, unprotected sex in the last year and lifetime experience of unintended pregnancy.
RESULTS: Many respondents reported arousal loss related to the use of safer-sex products (34%) or the risk of unintended pregnancy (46%). Participants who strongly agreed that use of safer-sex products can lessen their arousal were significantly more likely to have had unprotected sex in the last year than were those who strongly disagreed (odds ratios, 1.8 for men and 3.7 for women); those who strongly disagreed that pregnancy risk can lessen their arousal were significantly more likely to have been involved in an unintended pregnancy than were those who strongly agreed (2.0 for men and 1.4 for women). Arousal loss related to safer-sex practices was more strongly associated with unprotected sex among women than among men, whereas arousal loss related to pregnancy risk was more strongly associated with unintended pregnancy among men than among women.
CONCLUSIONS: Some men and women are turned off by safer-sex practices or by pregnancy risk. Given arousal profiles' potential contributions to unintended pregnancies and STD transmission, they should be integrated into sexual health behavioral models, research and programming. 相似文献

Theories and empirical studies of adolescent sexual behavior have identified the contributions of personal attributes and social experiences; however, it is rare that models have clarified developmental pathways to adolescent sexual behavior that include (1) factors assessed prior to and early in adolescence and (2) dyadic experiences in adolescence that provide the opportunity for sexual behavior (i.e., dating). Using data from a prospective study, structural equation modeling was used to test a model predicting adolescent sexual behavior at age 19, denoted by the number of lifetime sexual partners. Predictors examined were sociability and impulsivity assessed at 30 months of age, physical characteristics and experiences with peers measured at age 12-13, the age of first romantic relationship, and frequency of alcohol use at age 16. The pathway to greater sexual involvement was marked by some desired personal attributes (e.g., sociability) and peer experiences (e.g., higher quality friendships). These associations were mediated, however, by earlier initiation of romantic relationships and more frequent use of alcohol in middle adolescence. Earlier initiation of romantic relationships and more frequent alcohol use were predicted by greater sociability and less impulsivity in childhood, higher quality friendships and greater peer acceptance in early adolescence, and a more mature appearance and physical attractiveness (among females) at age 13. The findings imply a complex pathway that leads to a greater accumulation of sexual partners by age 19. This pathway begins in childhood and includes individual qualities, peer acceptance, romantic relationships, and alcohol use. 相似文献

Guided by a feminist perspective, the authors examined young men's recollection of their reactions to and the familial and social contexts in which they realized that they were seeing an explicit sexual image for the first time. The sample consisted of 199 young men enrolled in a human sexuality class who responded to questions regarding the what, when, where, with whom, and how they felt about and reacted to seeing a sexualized image. On average, participants were in elementary school and without adult supervision when they found their first image in a form of media that was readily available in the home. Implications for family life education for both parents and children include direct and knowledgeable communication about sexuality to counter the often sensationalizing, objectifying, and entitled culture in which boys are informally initiated into adult sexuality. 相似文献

This study aimed to build formative knowledge regarding HIV risks in female migrant sex workers in Moscow, focusing on gender and power. This was a collaborative ethnographic study, informed by the theory of gender and power, in which researchers conducted minimally structured interviews with 24 female sex workers who were migrants to Moscow and who provided sexual services to male migrant laborers. Overall, the female migrant sex workers engaged in HIV risk behaviors and practiced inadequate HIV protection with their clients. These behaviors were shaped by gender and power factors in the realms of labor, behavior, and cathexis. In the labor realm, because some female migrants were unable to earn enough money to support their families, they were pushed or pulled into sex work providing service to male migrants. In the behavior realm, many female migrant sex workers were intimidated by their male clients, feared violence, and lacked access to women's health care and prevention. In the cathexis realm, many had a sense of shame, social isolation, emotional distress, and lacked basic HIV knowledge and prevention skills. To prevent HIV transmission requires addressing the gender and power factors that shape HIV/AIDS risks among female migrant sex workers through multilevel intervention strategies. 相似文献

An attenuating sample of 87 male adolescent sexual offenders logged sexual fantasies during their entire time in therapy. These patients were attending residential treatment and kept a log recording all normal and deviant sexual fantasies which they experienced. Patients recorded which fantasies were interrupted and which fantasies were accompanied by masturbation. Typically, at the beginning of treatment, the reported rate of normal fantasies was maximal, the occurrence of deviant fantasies was minimal, and there was little effort to interrupt the deviant fantasies. The reported frequency of deviant fantasies increased substantially (about 380%) during the first 5 months of treatment and then steadily declined (approximately 47%) over the remaining months in therapy. Following an initial decline in the early months of treatment, an increase in the rates of normal fantasies was reported. Additionally, over the course of treatment, the frequency of deviant fantasies decreased relative to all fantasies. While deviant fantasies remained predominant to normal sexual fantasies and were more frequently paired with masturbation, patients reported substantial changes in the proportion of deviant fantasies that were interrupted (from about 20% to 70%). Implications of the results for juvenile sex offender treatment are discussed. 相似文献

Data are sparse on injection drug using (IDU) men who have sex with men (MSM). Previous literature suggests perceived taboos
can result in an underreporting of atypical sexual orientation (i.e., bisexuality, homosexuality). As a result, HIV prevention
programs have been difficult to mount, particularly programs for IDU-MSM. The association between self-reported sexual orientation
and sexual behavior at semi-annual study visits was longitudinally assessed in a population of 1300 male IDUs in Baltimore
during the period 1993 to 1998. Overall, a small minority (5%) of the male IDUs inconsistently reported their sexual orientation
over time. Logistic regression analyses were performed, which yielded five significant predictors. These men tended to be
older, to have been incarcerated, to have attended shooting galleries during follow-up, and were more than twice as likely
to be HIV-seropositive (OR, 2.66; 95% CI, 1.62–4.36) compared with those who consistently reported their sexual orientation.
Furthermore, men reporting inconsistent sexual orientation tended to engage in higher risk behaviors, suggesting that these
men should be especially targeted for interventions. 相似文献

The aims of this article are (1) to describe the prevalence of disclosure of HIV serostatus to sex partners among a racially/ethnically diverse sample of HIV-positive women living in Hawai'i and Seattle, Washington; and (2) to examine factors related to disclosure and condom use with those sex partners. HIV-positive women have difficulties consistently disclosing serostatus to sex partners and using condoms. Little is known about the disclosure practices of women from Hawai'i or Seattle. A cross-sectional design with convenience and snowball sampling was used, and up to three recent sex partner experiences were assessed among the HIV-positive participants (N = 84). A total of 133 recent sex partners were reported, with disclosure and condom use frequencies of 75.2 and 59.9%, respectively. Women who knew when it was safe to disclose were more likely to disclose. Women who disclosed to recent sex partners were less likely to use condoms, while those in casual/anonymous partnerships were more likely to use condoms. Hawaiian/part Hawaiian women had the lowest proportion of condom use. Health care personnel should routinely discuss disclosure and sexual transmission risk behaviors with seropositive women and offer strategies to enhance condom use, especially among those in committed partnerships. Culturally tailored interventions focused on strengthening efficacy beliefs for disclosure and condom use in Native Hawaiians are needed. 相似文献
