Sexual activity and condom use among Eastern European adolescents--the Study of Hungarian Adolescent Risk Behaviours

While rates of HIV and STD infection in Eastern Europe are increasing rapidly, little is known about sexual behaviour, including condom use, among Eastern European youths. The Study of Hungarian Adolescent Risk Behaviours was designed to assess the knowledge, attitudes, and behaviours of adolescents studying in secondary schools in Budapest, Hungary. Students (n =3486) in a random sample of public secondary schools completed a self-administered questionnaire, including measures of sexual activity and condom use. Thirty-eight percent of students reported ever having had vaginal intercourse. Condom use by those reporting having had sex in the past five weeks was classified as consistent/every time (40%); irregular (25.6%); and none (34.3%). Multivariate analysis revealed positive opinions about condoms, fear of AIDS, and initiation of condom use by both partners to predict more frequent condom use. Implications for targeted AIDS/STD education and prevention among adolescents are discussed.     

Sexual Risk and Bridging Behaviors Among Young People in Hai Phong,Vietnam

The risk of the HIV epidemic spreading from high-risk groups to the general population in Vietnam depends on sexual risk and bridging behaviors between high- and low-risk individuals. A cross-sectional study was used to describe sexual activities of youth aged 18-29 years. Nearly half (41.4%) were sexually active. Premarital sex was reported by 43.3% of them; 78.3% of sexually active males and 13.5% of sexually active females. Multiple sex partners were reported by 31.0%; 56.7% of males and 9.2% of females. Almost 27% of males and 5% of females engaged in sexual bridging behaviors. Being unmarried was significantly associated with having sex with non-regular partners. Being unmarried and early age at first intercourse were associated with having sex with a sex worker. Consistent condom use was high with commercial sex workers but low with regular partners. Education to delay early sexual debut, increased employment, and strategies to inform young sexually active people to adopt safer behaviors are urgently needed.

Predictors of Risky Sexual Behavior among Adolescents in Tanzania

Studies on sexual behavior among adolescents are fundamental in understanding and fighting against outcomes of unprotected sex that include unplanned/unwanted pregnancies and sexually transmitted diseases. This survey conducted among in- and out-of-schools adolescents measured prevalence of sexual behavior variables, including risky sexual behavior and associated factors. Risky sexual behavior was defined as having first sex before 16 years, inconsistent condom use and having multiple sexual partners. About 30% of adolescents reported being sexually active; a higher proportion being among males than females and 24.5% of sexually active adolescents reported having multiple sexual partners. More males (37%) reported having multiple sexual partners than females (26%). Nearly 48% of unmarried sexually active adolescents reported having used a condom during the most recent sexual intercourse. Predictors of risky sexual behavior were being male, young age (10–14 years) and being inschool. Preventive information and education should take into consideration these factors.     

HIV Risk Among Patients Attending Sexually Transmitted Disease Clinics in China

HIV and other sexually transmitted diseases (STDs) are spreading rapidly in China. However, little is known about HIV risk among STD patients. In October–November 1997, we recruited a consecutive sample of 1,371 STD clinic patients from 16 different provinces and municipalities across the country and examined their sexual practices and condom use. We found that the median age for sexual initiation was 22 years for men and 21 years for women, and only a small proportion of men (12%) and women (15%) had used a condom during this first sexual intercourse. Eighty-one percent of men and 53% of women had two or more sexual partners in the past year. During the same period, 78% of men and 44% of women had both steady and nonsteady partners; of those with both types of partners, only 1% of men and 7% of women always used a condom with these partners. Multiple sexual partnerships in the past year were more common among men, older men (over 35 years), and those who had initiated sex at an earlier age. More frequent condom use was associated with being younger, having nonsteady partners, and having used a condom during a first sexual encounter. Our findings underline a need for patient education and condom promotion among STD clinic patients as a part of efforts to prevent the spread of HIV in China.     

Covariates of high-risk sexual behaviour of men aged 50 years and above in sub-Saharan Africa

Since the advent of HIV/AIDS, sexuality studies in sub-Saharan Africa (SSA) have focused mainly on the sexual behaviour of the younger generation (15–49 years) and little has been done to understand the sexual behaviour of those a 50 years and above. The objective of this study is therefore to examine the covariates of high-risk sexual behaviour among men aged 50 years plus within the SSA region. Data from Demographic and Health Surveys of 10 SSA countries were pooled together and a sample of 5394 men aged 50 years plus who have ever had sex was analysed. Findings show that in SSA, a large proportion of men aged 50 years plus (74%) were sexually active and a substantial proportion of these men engaged in unsafe sexual behaviours, such as having multiple sexual partners and unprotected sex. The multivariate logistic regression analysis showed that involvement with multiple sexual partners was significantly associated with older age, urban residence, religion, having primary or secondary education, and ever taken an HIV test. Condom use at last sex was significantly associated with age at first sex, multiple sexual partners, level of education and ever been tested for HIV. These results suggest that HIV prevention and intervention programmes should also target older men as they are also sexually active and at risk of being infected because of unsafe sexual practices.     

Age at Sexual Initiation and Sexual and Health Risk Behaviors Among Jamaican Adolescents and Young Adults

Current policies limit access to sexual and reproductive health services for adolescents younger than 16 years in Jamaica. Using data from a national survey, we explored the relationship between age at sexual initiation and subsequent sexual risk behaviors in a random sample of 837 Jamaican adolescents and young adults aged 15–24 years. In the sample overall, 21.0% had not yet had sex. Among the 661 sexually active participants, the mean age at first sex was 14.7 years. High percentages of sexually active youth reported engaging in risk behaviors such as inconsistent condom use (58.8%), multiple sex partners (44.5%), and transactional sex (43.0%). Age of sexual initiation for males was unrelated to subsequent sexual risk behaviors. However, earlier sexual debut for females was associated with their number of partners during the preceding year. Findings underscore the potential benefits of access to sexual and reproductive education and services at earlier ages than current policies allow. Interventions before and during the period of sexual debut may reduce sexual risk for Jamaican adolescents and young adults.     

Sex, drugs and sexually transmitted infections in British university students

Understanding predisposing factors for sexually transmitted infections (STIs) in young adults may identify targets for public health interventions. We conducted a cross-sectional web-based survey of university students' sexual attitudes, behaviours and lifestyles and self-reported rates of STI. A total of 827 students responded, 22.4% had two or more sexual partners in the previous year with inconsistent condom use and the lifetime prevalence of STIs was 9.6%. Factors associated with a diagnosis of STI were increasing age and number of sexual partners ever, female gender (adjusted odds ratio [AOR] 2.70, 95% confidence interval [CI] 1.31, 5.56) and use of crack (AOR 10.45, 95% CI 1.46, 75.16). For female students, these were increasing age and number of partners ever, whereas for male students having sex with other men (bisexual AOR 4.8, 95% CI 1.02, 22.595, homosexual AOR 17.66, 95% CI 3.03, 103.04) and use of crack (AOR 32.24, 95% CI 3.33, 312.08). Multiple partners and recreational drug use may predict incidence of STI. Prevention strategies need to aim at reducing risk behaviour across various activities.     

Sexual assault history and risks for sexually transmitted infections among women in an African township in Cape Town, South Africa

Sexual violence is associated with women's risks for HIV infection. The current study investigated factors related to risks for sexually transmitted infections (STIs), including HIV, among South African women with a history of sexual assault. An anonymous street intercept survey of women (N = 272) living in an African township in the Western Cape, South Africa assessed demographic characteristics, history of sexual assault, HIV risk behaviours, substance use and non-sexual relationship abuse. Surveys were completed by 90% of women approached. Forty-four per cent (N = 119) of women reported a history of sexual assault. Multiple logistic regressions, controlling for participant age, education, marital status and survey venue, showed that women who had been sexually assaulted were significantly more likely to have shared injection drug equipment, exchanged sex to meet survival needs, and used alcohol compared to women who had not been sexually assaulted. Women with a history of sexual assault were also significantly more likely to have multiple male sex partners, greater rates of unprotected vaginal intercourse, lower rates of condom protected anal intercourse, more sexual contacts involving blood, more STIs and genital ulcers. Finally, women who had been sexually assaulted were more likely to have been non-sexually abused by relationship partners and were more likely to fear asking partners to use condoms. There is a close connection between sexual assault and women's risks for STIs and HIV. Structural and behavioural interventions are needed to simultaneously reduce the prevalence of sexual assault against women and prevent the transmission of HIV.     

Condom acquisition and preferences within a sample of sexually active gay and bisexual men in the southern United States

Health departments, community-based organizations (CBOs), and AIDS service organizations (ASOs) in the United States and abroad distribute large quantities of free condoms to sexually active individuals; however, little is known about where individuals who use condoms actually acquire them. This community-based participatory research (CBPR) study was designed to identify factors associated with the use of free condoms during most recent anal intercourse among self-identifying gay and bisexual men who reported condom use. Data were collected using targeted intercept interviewing during North Carolina Pride Festival events in Fall 2006, using the North Carolina Condom Acquisition and Preferences Assessment (NC-CAPA). Of the 606 participants who completed the assessment, 285 met the inclusion criteria. Mean age of participants was 33 (+/-10.8) years. The sample was predominantly white (80%), 50% reported being single or not dating anyone special, and 38% reported the use of free condoms during most recent anal intercourse. In multivariable analysis, participants who reported using free condoms during most recent anal sex were more likely to report increased age; dating someone special or being partnered; and having multiple male sexual partners in the past 3 months. These participants were less likely to report ever having had a sexually transmitted disease. Despite being in the third decade of the HIV epidemic, little is known about condom acquisition among, and condom preferences of, gay and bisexual men who use condoms. Although more research is needed, our findings illustrate the importance of free condom distribution.     

High-risk behaviour in young men attending sexually transmitted disease clinics in Pune, India

The present study reports sexual risk factors associated with HIV infection among men attending two sexually transmitted disease (STD) clinics in Pune, India and compares these behaviours between young and older men. Between April 1998 and May 2000, 1872 STD patients were screened for HIV infection. Data on demographics, medical history and sexual behaviour were collected at baseline. The overall HIV prevalence was 22.2%. HIV risk was associated with being divorced or widowed, less educated, living away from the family, having multiple sexual partners and initiation of sex at an early age. The risk behaviours in younger men were different to older men. Younger men were more likely to report early age of initiation of sex, having friends, acquaintances or commercial sex workers as their regular partners, having premarital sex and bisexual orientation. Young men were more educated and reported condom use more frequently compared with the older men. Similar high HIV prevalence among younger and older men highlights the need for focused targeted interventions aimed at adolescents and young men and also appropriate interventions for older men to reduce the risk of HIV and STD acquisition.     

Sexual behavior among employed male rural migrants in Shanghai, China.

A study of sexual behavior in migrant men was conducted in construction sites, markets, and factories in Shanghai, the largest city in China. An anonymous, self-administered questionnaire was completed by the migrants. Among 986 sexually active men, 14% had had more than one sexual partner in their lifetime, 31% premarital sex, 3.3% oral sex, and 11.5% commercial sex. Seventy-eight percent never used condoms. Risk-taking was similar in different working venues but increased with decreasing age. Younger men initiated sexual intercourse earlier and had more premarital sex and sexual partners as well as more frequent sexual encounters. Risk-factors that correlate with having multiple sex partners included having seen pornography, early age at initiating sexual intercourse, premarital sex, and a desire for legalization of commercial sex. Sexually transmitted diseases and HIV are likely to increase among migrants, particularly those who are young. Intervention strategies should target younger migrants, and must accommodate a low literacy level.     

Self-reported syphilis and associated factors among Brazilian young adults: findings from a nationwide survey

The aim of this study was to evaluate self-reported syphilis and associated factors in sexually active young adults (16–25 years old) in the Public Health System in Brazil. This was a cross-sectional study with 8071 participants recruited from 119 primary care units. Of these, 224 (2.86%, 95% CI 2.29–3.43%) reported having the disease. Age, lower socio-economic class, being a smoker, not using a condom at first sexual intercourse, and ever had a same-sex sexual experience were associated with syphilis. The results reinforce the importance of implementing strategies focused on socio-economic class and early sexual education that encourage condom use from the beginning of sexual activity.     

Sexual risk behaviors in the internet age: the case of Chinese men who have sex with men

ABSTRACT

This cross-sectional study examined a sample of sexually active Chinese MSM recruited online (N?=?403) to determine the associations of MSM social life (both online and in-person) and sexual identity stigma with three types of sexual risk behaviors in the past 12 months, including condom use %, number of anal intercourse partners, and number of partners engaged in condomless anal intercourse (CAI). Hierarchical regression analyses were conducted. More frequent use of social media was associated with higher numbers of anal intercourse partners as well as more condom use in past 12 months, but not number of CAI partners. More active in-person MSM social life was associated with higher numbers of partners in anal intercourse as well as CAI. Both perceived and enacted sexual identity stigma associated with higher numbers of CAI partners; perceived stigma was also linked to less condom use. In conclusion, social life and minority stress are relevant factors of sexual risk among MSM in China in the uptrend of internet use. The internet may be an important and promising platform for HIV prevention, and intervention efforts should consider online-based designs to promote safe sex and reduce sexual minority stigma.     

Factors associated with HIV among female sex workers in a high HIV prevalent state of India

The study was carried out to assess the factors associated with HIV seropositivity among female sex workers (FSWs) in Dimapur, Nagaland, a high HIV prevalence state of India. A total of 426 FSWs were recruited into the study using respondent driven sampling (RDS). Data on demographic characteristics, sexual and injecting risk behaviours were collected from them and were tested for HIV, Syphilis, Neisseria gonorrhoeae and Chlamydia trachomatis. RDS-weighted univariate and multivariate logistic regression analysis was performed to assess the factors associated with HIV seropositivity. Consistent condom use with regular and occasional sexual clients was 9% and 16.4%, respectively. About 25% of the participants ever used and 5.7% ever injected illicit drugs. RDS adjusted HIV prevalence was 11.6%. In the univariate analysis, factors associated with HIV were initiating sexual intercourse before the age of 15 years, ≥2 years duration of sex work, serving clients at lodge/hotel, positive test result for one or more sexually transmitted infections (STIs), lifetime history of injecting drug use, lifetime history of consuming illicit drugs, ever having exchanged sex for drugs, having sexual partners who engaged in risky injecting practices and having been widowed or divorced. In multivariate analysis, factors found to be independently associated with HIV included lifetime injecting drug use, initiating sexual intercourse before the age of 15 years, positive test result for one or more STIs and having been widowed. Injecting drug use was found to be most potent independent risk factor for HIV (OR: 3.17, CI: 1.02-9.89). Because of lower consistent condom use among them, FSWs may act as bridge for HIV transmission to general population from injecting drug users (IDU) through their sexual clients. The informations from this study may be useful for enriching the HIV preventions effort for FSWs in this region.     

The association between substance use, unplanned sexual intercourse and other sexual behaviours among adolescent students

Aims. To determine the prevalence of high-risk sexual behaviours and the influence of substance use and unplanned sexual intercourse on multiple sexual partners, inconsistent condom use and reasons for not always using condoms among adolescent students. Design. A standardized self-reported anonymous questionnaire administered to a representative sample of students. Setting. The Canadian provinces of Nova Scotia, New Brunswick, Newfoundland and Labrador, and Prince Edward Island in 1998. Participants. 9997 students in grades 9, 10 and 12 in the public school system. Measurements. Items on sexual intercourse, unplanned sexual intercourse, number of sexual partners, condom use, alcohol use, episodes of binge drinking and drunkenness, cigarette smoking and cannabis use. Findings. About 37.5% of males and 39.7% of females reported having engaged in sexual intercourse in the 12 months prior to the survey. Of those, 68.0% of males and 61.5% of females reported having engaged in unplanned sexual intercourse, 40.9% of males and 32.1% of females reported having more than one sexual partner, and 49.9% of males and 64.1% of females reported inconsistent condom use. Unplanned sexual intercourse under the influence of alcohol or other drug was found to be an independent risk factor for multiple sexual partners and inconsistent condom use. Conclusion. The demonstration of an association between substance use, unplanned sexual intercourse and other sexual behaviours lends support to a harm minimization approach, including the provision of non-judgemental information and interventions addressing unplanned sexual intercourse under the influence of a substance.     

High levels of unprotected sex with men and women among men who have sex with men: a potential bridge of HIV transmission in Beijing, China.

China is experiencing an emerging HIV epidemic among men who have sex with men (MSM). We investigated sexual risk, risk perception, HIV and condom knowledge, and utilization of prevention services in the first large sample of MSM recruited in Beijing. Four hundred eighty-two MSM were sampled from September 2001 to January 2002. Forty-nine percent of participants reported unprotected anal intercourse with men during the previous 6 months. However, only 15% perceived they are at risk for HIV and many had misconceptions about HIV transmission routes and limited knowledge about condoms. Less than one quarter obtained free condoms (24%) and condom lubricants (19%) in the past 2 years. Multiple logistic regression analysis showed that unprotected insertive anal intercourse was associated with not having a Beijing residence card, having six or more male sexual partners, not having sex with women, having a lifetime history of sexually transmitted diseases (STDs), and having never tested for HIV. Unprotected receptive anal intercourse was independently associated with having six or more male sexual partners, not having sex with women, having a lifetime history of STDs, having never tested for HIV, and having less exposure to HIV prevention services. In addition, 28% reported having sex with both men and women during the previous 6 months, and 11% had unprotected intercourse with both men and women. This finding suggests that MSM are a potential bridge of HIV transmission to heterosexual women (or vice versa) and that addressing the HIV prevention needs of MSM may benefit the wider population.

Predicting Primary and Secondary Abstinence Among Adolescent Boys and Girls in the Western Cape,South Africa

Two of the most effective health behaviours with regard to HIV prevention are condom use and sexual abstinence. While determinants of condom use among sub-Saharan African adolescents have been studied extensively, factors related to abstinence have received far less attention. This study identified socio-cognitive determinants of primary and secondary abstinence intentions and of early sexual activity. This study also assessed whether these factors had a direct or indirect association with intentions to abstain from sex. A longitudinal design was used in which 1670 students (age 12–16) of non-private South African high schools filled in a questionnaire, with a follow-up after 6 months, concerning sexual abstinence, attitudes, social norms, self-efficacy, risk perception and knowledge. Logistic and linear regression analysis with latent factors was used to assess determinants of intentions and abstinence, and structural equation modelling was used to assess indirect effects. Results showed that among sexually inactive students, social norms predicted the intention to abstain from sex in the next 6 months. Among sexually active students, reporting less disadvantages of abstinence predicted the intention to abstain. Sexual activity at follow-up was predicted by attitudes and intention among sexually inactive girls, and by knowledge among sexually inactive boys. No predictors were found for sexually active adolescents. Structural equation modelling further showed that risk perception was indirectly related to intentions to abstain from sexual intercourse. We conclude that addressing socio-cognitive factors in order to motivate adolescents to delay sex is more likely to be successful before they experience sexual debut. In addition, this study shows that the effect of increasing risk perceptions, a strategy often applied by parents and HIV prevention programmes, is to a large extent mediated by more proximal cognitive factors such as attitude. Research is needed to identify factors that influence the execution of intentions to abstain from sex.
