Alcohol consumption and sexually transmitted disease risk behavior: partner mix among male Korean university students.
BACKGROUND: This study examined alcohol consumption and sexually transmitted disease risk behavior as related to prostitute visits and sex partner mix among male Korean university students in 1993 to 1994. METHODS: Questionnaires were completed by a representative sample of 1103 university students in Seoul. Lifetime sexually transmitted disease risk behavior was categorized as none, only one, and multiple sexual experiences with prostitutes, whereas risk according to partner mix was classified as no sexual experience with prostitutes, sexual experience with prostitutes only, and with both prostitutes and girlfriends. The proportional odds model was applied to the data. RESULTS: A total of 25.8% of the university students had visited prostitutes--17.6% visited twice or more, and 12.9% had sexual experiences with both prostitutes and girlfriends. Heavier alcohol consumption was significantly related to multiple visits to prostitutes (odds ratio = 1.71) and to sexual experiences with both prostitutes and girlfriends (odds ratio = 2.30). CONCLUSIONS: In this first systematic study of the association between alcohol consumption and sexual experiences among Korean male university students, alcohol use was associated with risky sexual behaviors, and with first and most recent sexual experience with prostitutes, supporting our hypotheses.

Determinants of condom use in 24,000 prostitute/client contacts in The Gambia.
OBJECTIVE: To determine the factors that influence condom use among prostitutes and their clients in The Gambia. DESIGN: A cohort of 181 prostitutes working in seven bars and several rural markets in The Gambia were monitored daily for 14 months. A sample of 747 clients of these prostitutes was also questioned. MAIN OUTCOME MEASURE: Proportion of sexual contacts for which a condom was used. RESULTS: Data on 24,181 sexual contacts reported by the prostitutes indicated condom use varied according to type of partner (from 84% with clients to only 4% with regular partners). Condom use with clients varied according to location (from 91% in high-class bars to 59% in rural markets), decreased from 91% with the first client of the evening to 37% with the tenth client, and from 75% with clients paying higher charges (> D19) to 52% with those paying lower charges (< D20). Condom use was not related to the socio-demographic characteristics of the prostitutes. Clients reported lower condom use than prostitutes. Clients aged 20-24 years were least likely to use condoms, while white collar workers, traders, and those paying higher charges, were more likely to use condoms. CONCLUSIONS: The level of condom use in this cohort of prostitutes was high but not consistent. Condom use was determined more by the type of establishment and the characteristics of clients, than by any fixed tendency among the prostitutes. Thus, education campaigns should be directed as much to clients as to prostitutes. In The Gambia, 'lower-class' bars and those in rural areas where prostitutes work should be a priority target.

HIV-1, HIV-2, and HTLV-I infection in high-risk groups in Brazil.
We conducted a serologic survey for antibodies to human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2) and human T-cell lymphotropic virus Type I (HTLV-I) in 704 Brazilians with the acquired immunodeficiency syndrome (AIDS) or at risk for it. The study population included 70 homosexual men (11 of whom were prostitutes), 58 bisexual men (19 of whom were prostitutes), 101 female prostitutes from three socioeconomic groups, 13 wives of men with hemophilia who were seropositive for HIV-1 antibodies, and 47 blood donors with positive Venereal Disease Research Laboratory tests for syphilis, all from Rio de Janeiro; 86 female prostitutes from two rural towns in Minas Gerais; 133 patients with AIDS from São Paulo; and 196 men with bleeding disorders who were seropositive for HIV-1 antibodies on enzyme-linked immunosorbent assay, from São Paulo and Rio de Janeiro. The prevalence of HIV-1 infection was highest in the homosexual male prostitutes (45 percent), the wives of patients with hemophilia (38 percent), the bisexual men (28 percent), the homosexual men who were not prostitutes (19 percent), and the female prostitutes from the lower class (9 percent). Combined HIV-1 and HIV-2 infection was found in 3 percent of the patients with AIDS and in 1 percent of the homosexual men. The prevalence of HTLV-I infection ranged from 1 percent in rural female prostitutes to 13 percent in HIV-1-positive men with bleeding disorders in Rio de Janeiro. Combined HIV-1 and HTLV-I infection occurred in 1 to 11 percent of some male subgroups. We conclude that in Brazil HIV-1 infection is already well established among homosexuals, bisexuals, and lower-class female prostitutes, with bisexual men probably acting as a bridge between the heterosexual and homosexual communities, that HTLV-I infection is prevalent in groups at risk for AIDS, and that HIV-2 infection has already been introduced into the country.

Sexual transmission of hepatitis D virus infection in Taiwan.
Multivariate analysis of the risk factors for hepatitis D virus infection among 53 men with acute hepatitis D virus superinfection, 59 men with acute exacerbation of chronic hepatitis B and 54 asymptomatic male hepatitis B carriers revealed that sexual contact with prostitutes and use of nondisposable needles were the factors significantly associated with hepatitis D virus infection in Taiwan (odds ratio = 5.5, 95% confidence interval = 3.3 to 9.2; odds ratio = 2.4, 95% confidence interval = 1.3 to 4.4, respectively). The prevalence of antibody to hepatitis D virus antigen among hepatitis B virus carriers with histories of sexual exposure to prostitutes was 10.3% (14 of 136) and the prevalence of hepatitis D virus antigen among the female prostitutes who were hepatitis B virus carriers was 59% (24 of 51). Among those who admitted to sexual contact with prostitutes, testing for hepatitis D virus antigen revealed positive correlations with the frequency of such sexual contacts and with the frequency of history of venereal diseases. Among the female prostitutes, the prevalence of hepatitis D virus antigen had a positive correlation with the frequency of sexual contact and a negative correlation with age. Analysis of serum hepatitis D virus RNA among those with hepatitis D virus antigen revealed that 4 of the 9 with sexual exposure to prostitutes and 3 of the 24 prostitutes were positive. From these findings, we conclude that these two groups are not only at high risk for hepatitis D virus infection but also form a reservoir of this virus.

Changing seroepidemiology of hepatitis B, C, and D virus infections in high-risk populations.
Needle-sharing and sexual contact are important transmission routes of hepatitis B, C, and D virus (HBV, HCV, HDV) infection. This study aimed to investigate the current status of these viral infections among high-risk populations including prostitutes and intravenous (i.v.) drug users, compared with the prevalence rate reported previously to examine the changing seroepidemiology. Of the 916 female prostitutes, 79 (9%) were positive for antibody to HCV (anti-HCV), 111 (12%) were positive for HBV surface antigen (HBsAg), and 5 (5%) had antibody to HDV (anti-HDV). The prevalence rate was significantly lower compared to that in 1989-1991 (12%, P = 0.037) for HCV infection, and to that in 1988 (59%) and 1996 (40%) (P < 0.0001) for HDV infection. Of the 494 i.v. drug users, 87 (18%) patients were HBsAg carriers and 12 (14%) were anti-HDV-positive. The prevalence rate of HDV infection was significantly lower than that reported in 1985 (79%, P < 0.0001). Among the 443 tested i.v. drug users, 182 (41%) were anti-HCV-positive, significantly lower than that in 1985 (53%, P = 0.026). Of the 263 male prostitutes, 11 (4%) were anti-HCV-positive, 45 (17%) were HBsAg-positive, and 7 (16%) were anti-HDV-positive. Of the 129 illegal immigrant prostitutes, 7 (5%) were anti-HCV-positive, 15 (12%) were HBsAg-positive and none were positive for anti-HDV. In conclusion, the findings indicate a declining prevalence of HCV and HDV infections among drug users and prostitutes over the past 16 years. Male prostitutes and immigrant prostitutes are new "high-risk" populations and may become a reservoir for disease transmission.

Accuracy of two enzyme immunoassays and cell culture in the detection of Chlamydia trachomatis in low and high risk populations in Senegal.
Two enzyme immunoassays (EIAs), Chlamydiazyme (CZ; Abbott Laboratories) and Pathfinder (PF; Kallestadt), were compared with a cell culture technique in the detection of cervical Chlamydia trachomatis infection in 670 women in urban settings in Senegal (377 pregnant women and 293 prostitutes). Positive CZ and positive PF specimens were tested a second time using a monoclonal antibody blocking technique. True positive specimens were defined as those positive on culture or positive on EIA with confirmation of the result after blocking. Using this definition, the prevalence of genital chlamydial infection was 14.6% and 14.3% in pregnant women and prostitutes respectively. An important difference between the two populations was that the pregnant women were younger than the prostitutes, which might explain the fact that the prevalence of infection among the pregnant women was as high as that among the prostitutes, although the age-adjusted prevalence was higher among prostitutes than among pregnant women. The chlamydial detection rates of cell culture, CZ and PF were 62% (26/42), 69% (29/42) and 86% (36/42) respectively in prostitutes and 76% (42/55), 40% (22/55) and 53% (29/55) respectively in pregnant women. Agreement between the tests was 89%, 85% and 88% for culture/CZ, culture/PF and CZ/PF respectively. However, when data were adjusted for chance agreement, kappa coefficients were 0.40 for culture/CZ, 0.34 for culture/PF and 0.48 for CZ/PF. These results indicate that the accuracy of the EIAs and cell culture may vary greatly in different populations: both EIAs showed a distinctly higher detection rate than culture in prostitutes and a significantly lower detection rate in pregnant women.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatitis B and human immunodeficiency virus infection in street youths in Toronto, Canada.
Hepatitis B and human immunodeficiency virus are transmitted by venereal contact or by the sharing of used needles during drug use. A questionnaire was administered to street youths admitting to prostitution and to a group denying prostitution, as well as to sexually active adolescents who lived with their family and were attending an adolescent medical clinic. The age, gender, race, number of sexual partners, condom use, illicit drug use, anal intercourse and admission to prostitution were recorded for each of the subjects. Serology was obtained for hepatitis B markers and human immunodeficiency virus antibody. Multiple regression analysis was performed to determine the factors which might predict hepatitis B serologic status. A single subject, who admitted to prostitution, was found to be human immunodeficiency virus-seropositive. Seven of 43 (16%) admitted prostitutes compared with 1 of 44 (2%) other street youth and none of 27 controls demonstrated anti-hepatitis B surface antibodies. The higher rate of seropositivity in admitted prostitutes was statistically significant (P less than 0.0097). Two seropositive prostitutes had IgM hepatitis B core antibody suggesting recent infection. Two factors, number of partners (P less than 0.0007) and practice of anal intercourse (P less than 0.05), were identified in the multiple regression analysis as predictive of seropositivity. Thus adolescents who live on the street are at increased risk for becoming infected with hepatitis B virus. The difficulty in ensuring vaccine coverage in this population would support calls for including hepatitis B vaccination as part of childhood immunization.

[An epidemiological study of HBV and HTLV-I among high risk groups in Fukuoka City].
Sera from 69 adult prostitutes, 139 juveniles in the reformatory for boys, and 63 juveniles in the reformatory for girls, were collected between 1986 and 1987 in Fukuoka City. These samples were tested for the presence of antibody to human T-cell leukemia virus type-I (anti-HTLV-I), for hepatitis B surface antigen (HBsAg), and for antibody to hepatitis B core antigen (anti-HBc). The juveniles in the reformatory for girls were surveyed for the incidence of venereal diseases (VD) and for a history of intravenous drug use. Anti-HTLV-I was detected in 5.8% of the prostitutes, 0.7% of the boys, and 1.6% of the girls. Prevalence of anti-HTLV-I among the prostitutes was higher than that among the controls, but no significant difference was recognized. HBsAg was detected in 7.2% of the prostitutes, but was absent in the boys and girls. Prevalence of HBsAg among the prostitutes was higher than that among the controls, but no significant difference was recognized. Anti-HBs was detected in 39.1% of the prostitutes, 10.1% of the juvenile boys, and 17.5% of the juvenile girls. In each group prevalence of anti-HBc was higher than that in the controls. Especially between the prostitutes and the controls a significant difference was recognized (p less than 0.005). In the reformatory for girls anti-HBc was detected in 40.0% of 11 girls who were exposed to VD and in 7.0% of 43 girls who were not exposed to VD. Prevalence of anti-HBc among the exposed group was significantly higher than that among the non-exposed group (p less than 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)

Characteristics of gonorrhoea in Kermanshah, Iran.
OBJECTIVE: To describe the characteristics of gonorrhoea and prostitution in Kermanshah, Iran. METHOD: From 1997 through 2000, 100 male gonorrhoea patients were followed for a mean of 18 months (range 8-42 months). Diagnosis and follow up were made by a combination of history, physical examination, and the Gram stained smear. RESULTS: 4% of patients became infected by girlfriends, 24% by temporary (sigheh) wives, and 64% by street prostitutes; the remaining 8% denied coitus with sex workers. Of 38 married cases, 31 reported unprotected intercourse with permanent wives while infected, and only four of 38 gave prescribed drugs to their wives. 89% of contacts with prostitutes were unprotected. Most of the prostitutes and professional sigheh wives were practising survival sex. Fear of stigmatization and presumed severe penalties prevented prostitutes from seeking medical care, and 26% of patrons reported self medication. An average 84% of prescriptions of standard therapies failed. 31% of the cases remained refractory to all available therapies. CONCLUSIONS: The majority of the prostitutes and sigheh wives in Iran exchange sex for survival. Being uneducated survival sex workers, they accept risky sex behaviours easily. Sigheh wives are an important source of infection. The very high rate of persistent infection despite standard treatments is disturbing. Our ideal is a world in which nobody is obliged to enter commercial sex work. In the meantime, however, there is an urgent need to offer medical care and education to sex workers as needy patients in a safe and unprejudiced environment. Denying the presence of such realities as prostitution and sexually transmitted diseases (STDs) because of their disagreement with cant claims and official propaganda, does not eradicate the facts but results in catastrophic public health problems.

Hepatitis B virus infection and vaccination status of high risk people in Sydney: 1982 and 1991.
OBJECTIVES: To determine the change in prevalence of hepatitis B virus infection among "at risk" patients attending the Sydney Sexual Health Centre between 1982 and 1991 and to determine the hepatitis B vaccination status of the 1991 group. STUDY POPULATION: Consecutive patients attending the Centre between 1 July and 31 December 1991 who belonged to at least one of the following risk groups: men who have sex with men (n = 351); female prostitutes (n = 124); and injecting drug users (n = 153). DESIGN: Hepatitis B infection status was assessed on the basis of patient history and blood testing. All patients without a history of hepatitis B infection or vaccination were offered screening for serum markers of hepatitis B infection. Hepatitis B infection status was correlated with age, sex, country of birth, sexual behaviour and injecting drug use and was analysed separately according to risk category. RESULTS: The prevalences of any hepatitis B marker were: men who have sex with men 38.2% (61.0% in 1982; P < 0.0001); local female prostitutes 14.1% (28.8% in 1982; P = 0.024); international female prostitutes 58.4%; and injecting drug users 42.0%. Of those in the 1991 sample without a history of hepatitis B infection, 27.6% of men who have sex with men, 27.9% of local female prostitutes, 18.2% of international female prostitutes and 7.1% of injecting drug users were vaccinated. CONCLUSIONS: The significantly lower prevalences of serum markers of hepatitis B infection among men who have sex with men and local female prostitutes when compared with 1982 suggest widespread adoption of safer sexual practices. The high prevalence of chronic hepatitis B infection among international female prostitutes indicates a potentially significant source of sexually transmitted hepatitis B infection in Sydney. The low vaccination rates provide an argument for mass vaccination against hepatitis B.

[The HIV epidemic in Burkina Faso: current status and the knowledge level of the population about AIDS, 1994-1995].
BACKGROUND: It is important for HIV/AIDS control programmes to determine population knowledge on AIDS in order to develop appropriate Information, Education and Communication (IEC) messages. The objectives of our study were to determine the seroprevalence of HIV and syphilis among pregnant women, female prostitutes and long-distance truck drivers and to evaluate knowledge, attitudes, beliefs, and practice (KABP) with respect to the HIV/AIDS epidemic in these three groups in Burkina Faso. METHODS: We performed three cross-sectional serosurveys including face-to-face interviews on KABP between October 1994 and February 1995 in three population groups. RESULTS: Overall, 1,294 pregnant women, 236 long-distance truck drivers and 426 female prostitutes were recruited. HIV seroprevalence was 8% (95% Confidence Interval (CI): 6.6-9.6) among pregnant women, 18.6% (95% CI: 13.9-24.2) among long-distance truck drivers and 58.2% (95% CI: 53.4-62.9) in female prostitutes. The prevalence of syphilis was 2.5%, 9.3% and 15%, respectively. Most pregnant women (98%), long-distance truck drivers (96%) and female prostitutes (98%) had already heard of AIDS. However, the level of knowledge of HIV transmission routes, of risk factors for HIV transmission and of available preventive measures was very low. Consequently, 41% of pregnant women, 40% of long-distance truck drivers and an alarming 61% of female prostitutes reported that they did not feel themselves at risk for HIV. In each group, high levels of knowledge on AIDS were associated with increased awareness of AIDS risk and the adoption of preventive behaviours. Level of education was associated with knowledge of AIDS and condom use. However, in the 12 months preceding the surveys, condom use was very low among pregnant women (0.1%), long-distance truck drivers (18%) and among female prostitutes (42%). CONCLUSIONS: These results indicate that HIV is widespread in Burkina Faso and that there is an urgent need to develop and evaluate HIV prevention strategies in the general population and among core groups such as female prostitutes and long-distance truck drivers. Interventions must include information campaigns, condom promotion and distribution, and sexually transmitted diseases control.

HIV-1 infection in Juba, southern Sudan.
Thirty years of civil war in the Sudan have resulted in the isolation of the southern provinces which border Central and East Africa. Consequently, little is known about the epidemiology of HIV-1 infection in this region. To estimate the prevalence of HIV-1 infection in southern Sudan and the risk factors associated with disease transmission, a seroepidemiologic survey was conducted in the township of Juba. Study subjects invited to participate in this study included medical outpatients, inpatients hospitalized for active tuberculosis, and female prostitutes. A total of 401 subjects participated in the study. HIV-1 infection was confirmed in 25 subjects. The prevalence of HIV-1 infection was 19% (8/42) among tuberculosis patients, 16% (8/50) among prostitutes, and 3% (9/309) among outpatients. A significantly higher prevalence of HIV-1 infection was found among female prostitutes when compared to female outpatients: 16% (8/50) vs. 2% (4/178), P < 0.001. Correspondingly, the prevalence of seropositives was significantly higher among male outpatients reporting a history of sexual relations with prostitutes during the prior 10 years compared to male outpatients denying relations with prostitutes: 14% (5/37) vs. 0% (0/94), P = 0.0011. A history of a sexually transmitted disease (STD) was also associated with HIV-1 infection among male outpatients. The findings of this study indicate that HIV-1 infection is highly prevalent in southern Sudan and that prostitutes and their sexual partners represent a major reservoir of HIV infection in this population. This epidemiologic pattern resembles that seen in the African nations neighboring southern Sudan.(ABSTRACT TRUNCATED AT 250 WORDS)

Condom use by Dutch men with commercial heterosexual contacts: determinants and considerations.
We report responses from 559 clients of female prostitutes, with a view to determining to what extent previously identified factors play a part in condom use. To increase the response rate to advertisements in daily and weekly newspapers, interviews were held by phone. This procedure had the advantage of ensuring the anonymity many clients demanded. Of those clients having vaginal or anal contact (91%), 14% had not always used condoms in the previous year. Compared with consistent condom users, these men were less highly educated, had twice as many commercial contacts, and had more contacts with "steady" prostitutes. They were either more emotionally motivated to visit prostitutes than were consistent condom users or exhibited a stronger need for sexual variation. They showed a more compulsive attitude toward visiting prostitutes, had a more negative attitude toward prostitution in general, evaluated condoms more negatively, had a higher personal efficacy to achieve unsafe contacts, and had a higher general risk assessment, commensurate with their behavior. Men with only safe contacts had either an intrinsic or an extrinsic motivation for condom use. Among extrinsically motivated men, their behavior change was more recent and had not yet taken root: They still envisioned unsafe commercial sex to be possible in the future. Education aimed at the small group of men practicing unsafe contacts will not easily and directly lead to behavior change. But these educational activities may support prostitutes to persist in (consistent) condom use, regardless of clients' pressure to do otherwise.

Current seroepidemiology of hepatitis D virus infection among hepatitis B surface antigen carriers of general and high-risk populations in Taiwan.
In order to assess the current seroepidemiology of hepatitis D virus (HDV) infection in Taiwan where hepatitis B virus (HBV) is hyperendemic, a total of 756 voluntary blood donors, 641 prostitutes, 1,014 patients with sexually transmitted diseases (STDs), and 628 drug abusers were studied. Radioimmunoassays were used for testing HBV infection markers and antibody against HDV (anti-HDV) among HBsAg carriers. The anti-HDV prevalence among HBsAg carriers was significantly higher in STD patients (9.6%), prostitutes (33.1%), and drug abusers (68.1%) than in blood donors from the general population (2.2%). The prevalence gradually increased with age in blood donors and STD patients, but reached a plateau at a young age in prostitutes and drug abusers. Males had a higher prevalence than females in blood donors (2.7% vs. 0), STD patients (8.2% vs. 7.5%), and drug abusers (69.0% vs. 57.1%), but the difference was not statistically significant. STD patients with syphilis had a higher prevalence (19.5%) than those affected with non-ulcerating STDs (5.3%). While unlicensed prostitutes had a lower prevalence (13.6%) than licensed prostitutes (44.9%), intravenous drug abusers had a higher prevalence (73.1%) than non-intravenous drug abusers (34.6%). There was a twofold increase in anti-HDV prevalence from 1986 to 1989 among prostitutes, but the prevalence remained unchanged in the general population and drug abusers. HDV infection remains limited to the high-risk groups and spread mainly by promiscuity and needle sharing in Taiwan.

From bag brides to skeezers: a historical perspective on sex-for-drugs behavior.
There are many ways that women support their use of crack cocaine, including sex-for-crack bartering and other forms of prostitution. Empirical studies conducted in the mid-1970s and in the mid-1980s in New York City, and in Chicago in the late 1980s to early 1990s are compared, analyzing similarities and differences between the contemporary crack-prostitution scene and previous prostitution scenes. Findings suggest that the arrival of crack cocaine has directly and indirectly affected the drugs-prostitution nexus by lowering the price of sex for street prostitutes, altering the social status of cocaine, and increasing the level of social disorganization in illicit street activities, including prostitution. Barterers are shown to be the heaviest drug users, using the greatest variety of drugs, using larger amounts of drugs, and using more frequently.
