Prevalence of herpes simplex type 2 and syphilis serology among young adults in a rural Gambian community

OBJECTIVES: To estimate prevalence and risk factors for herpes simplex 2 (HSV2) positivity, syphilis and Chlamydia trachomatis infection among rural people aged 15-34 in the Gambia. METHODS: Questionnaires and serum samples were collected from 1076 men and women aged 15-34 during a cross sectional prevalence survey in a rural area of the Gambia. Sera were screened for antibodies to herpes simplex virus type 2 (HSV2), and for syphilis using Treponema pallidum haemagglutination assay (TPHA) and rapid plasma reagin (RPR) tests. Urine was tested by polymerase chain reaction (PCR) for C trachomatis infection. RESULTS: 28% of women and 5% of men were HSV2 ELISA positive; 10% of women and 2% of men were TPHA positive; and 7% of women and 1% of men were both RPR and TPHA positive. Out of 1030 urine sample tested only six were positive for C trachomatis. 7% of those who reported never having sex were positive for one or other of these tests. Prevalences of all STIs increased with age and were higher in women than men. Women were much less likely than men to seek treatment for STI symptoms at a health centre. Married people were at increased risk of an STI compared with single people. Jola and Fula women had a higher prevalence of HSV2 than women from other ethnic groups, and Fulas also had a higher prevalence of RPR/TPHA positivity. The limited number of sexual behaviour questions were not significantly associated with STIs after adjustment for age, marital status, and ethnic group. CONCLUSIONS: The prevalences of the ulcerative infections HSV2 and syphilis in this population are a cause for concern. In a setting where HIV1 prevalence remains low this indicates an urgent need for STI control and behaviour change programmes to prevent an HIV epidemic. Concerns about the validity of reported sexual behaviour data high light the necessity of biological markers in the evaluation of behaviour change programmes.     

Prevalence of sexually transmitted infections and high-risk sexual behaviors in heterosexual couples attending sexually transmitted disease clinics in Peru

OBJECTIVES: The objectives of this study were to determine the prevalence of sexually transmitted infection (STIs) in heterosexual couples and the sexual behaviors associated with their acquisition. GOAL: The goal of this study was to better direct educational efforts to decrease STI among heterosexual couples in Lima, Peru. STUDY DESIGN: We conducted a case-control study in 195 heterosexual couples without HIV infection who attended 2 sexually transmitted disease clinics in Lima, Peru. A case was defined as an individual with one or more newly diagnosed STIs such as gonorrhea, chlamydia, trichomoniasis, herpes simplex, syphilis, mycoplasma, or ureaplasma. RESULTS: Thirty-three percent of individuals (41 men and 89 women) had at least one STI and 26 couples (13%) had the same STI detected. Men who have sex with men (MSM) accounted for 13% of all men, had higher rate of STIs and higher risk behaviors than non-MSM. Ureaplasma infection was the most prevalent STI found in both men and women and was associated with oral sexual contact. In heterosexual pairs, condom use during anal sex occurred less than 10% of the time. CONCLUSIONS: The heterosexual couples in sexually transmitted disease clinics have high-risk behaviors and STIs are frequent. The educational effort concerning prevention of STIs requires higher effort.     

Incident sexually transmitted infections among persons living with diagnosed HIV/AIDS in New York City, 2001-2002: a population-based assessment

OBJECTIVE/GOAL: To describe the incidence of 3 bacterial sexually transmitted infections (STIs) among persons living with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) (PLWHA) in New York City (NYC) and to identify predictors for STI acquisition. STUDY DESIGN: The surveillance registry of PLWHA diagnosed with HIV through December 31, 2000, and reported to the NYC Department of Health and Mental Hygiene was matched with the surveillance registry of persons diagnosed with other STIs during 2001-2002. Incident STIs were defined as cases of gonorrhea, chlamydia, or early syphilis acquired after HIV diagnosis. RESULTS: Among 62,264 NYC PLWHA, 1466 (2.4%) had an incident STI diagnosed during 2001-2002. Two-year cumulative STI incidence was highest among PLWHA who were men (2.6%), non-Hispanic white (3.2%), aged 13-24 years (8.4%), men who have sex with men (4.5%), and persons living with HIV (non-AIDS) (4.1%). Predictors of STI acquisition among PLWHA varied substantially by STI type. CONCLUSIONS: This population-based surveillance registry cross-match reveals that high-risk sexual practices occur among specific segments of the NYC PLWHA population. To decrease associated morbidity and prevent the secondary spread of HIV and STIs, prevention efforts should focus on PLWHA who continue to engage in high-risk sexual activity.     

High prevalence of HIV and sexually transmitted infections among indirect sex workers in Cambodia

OBJECTIVES: The goal of this study was to assess the baseline prevalence of and risk factors for HIV and other sexually transmitted infections (STIs) among beer girls enrolled in a behavioral intervention in Battambang, Cambodia. METHODS: Ninety-two of 114 women participated in baseline interviewing, HIV/STI testing, and STI treatment. Blood specimens were tested for syphilis and HIV infection. Self-administered vaginal swabs were tested for trichomonas, bacterial vaginosis (BV), gonorrhea, and chlamydia infections. RESULTS: HIV prevalence was 26%. STI prevalences were: 14% chlamydia, 12% trichomonas, 3% gonorrhea, and 0% syphilis. The prevalence of BV was 43%. A history of sex work was reported by 82%. Consistent condom use with clients was reported by 39%. Increased number of partners and symptoms of STI were significantly associated with HIV infection. DISCUSSION: These data suggest high sexual risk among beer girls in Cambodia. Targeted and frequent HIV and STI interventions are urgently needed in this population.     

Sexually transmitted infections and risk factors among truck stand workers in Dhaka, Bangladesh

OBJECTIVE: This study was conducted to determine the prevalence of selected sexually transmitted infections (STIs) and their risk factors among workers in and near a truck stand in Dhaka, Bangladesh. STUDY DESIGN: A random sample of 696 men and 206 women were recruited into a cross-sectional study using a census that enumerated transport agents, motor mechanics, laborers, and vendors in Tejgaon truck stand. RESULTS: The prevalence rates of syphilis (rapid plasma reagin and Treponema pallidum hemagglutination), gonorrhea (polymerase chain reaction [PCR]), and chlamydial infections (PCR) among men were 4.1%, 7.7%, and 2.3%, respectively, and among women were 2.9%, 8.3%, and 5.2%. Multivariable analysis revealed that having >or=2 sex partners in the last month, never using a condom with sex workers, and ever injecting narcotics were significant predictors of STI among men. Being never married, working as a laborer, older age, and living within the truck stand were significant predictors of practicing high-risk behaviors among men, but none predicted infection with STIs. CONCLUSIONS: Both behavioral and STI data suggest that truck stand workers should be included in the STI/HIV intervention programs.     

Variations of HIV and STI prevalences within communities neighbouring new goldmines in Tanzania: importance for intervention design

OBJECTIVES: To measure the prevalence of HIV and other STIs in communities neighbouring new large scale gold mines in northern Tanzania in order to inform the design of a targeted HIV/STI intervention programme. METHODS: Cross sectional surveys were conducted in adults aged 16-54 years from different sectors of communities neighbouring two newly opened, large scale gold mines near Lake Victoria. Mine workers, men, women, and female food and recreational facility workers (FRFW) from the community were randomly selected for interview and HIV and STI testing. RESULTS: 207 male Tanzanian mine workers, 206 FRFW, 202 other male and 205 female community members were enrolled. Overall, 42% of FRFW were HIV positive, compared to 6% of male mine workers, and 16% and 18% of other community men and women respectively. HIV prevalence in FRFW was significantly associated with alcohol consumption (adjusted odds ratio (aOR) = 2.5, 95% confidence interval (CI) 1.1 to 5.5), past or present syphilis (TPPA+) (aOR = 2.7, 95% CI 1.4 to 5.1) and single status (aOR = 3.8, 95% CI 1.2 to 11.9). Among FRFW, 24% had active syphilis (RPR+, TPPA+), 9% Chlamydia trachomatis, and 4% Neisseria gonorrhoeae. Overall, 50% of FRFW and 50% of community men never used condoms during sex, and 55% mineworkers, 61% male, and 20% female community members reported receiving/giving payment for sex during the previous year. CONCLUSIONS: There is a high prevalence of HIV and other STIs in communities around new goldmines in Tanzania, especially in FRFW. HIV and STI prevalence in the mining workforce is still relatively low, but high risk sexual behaviour is reported by all adult subgroups surveyed in this study. Programmes focusing on HIV/STI prevention, with targeted interventions for high risk women such as FRFW, will be extremely important in such high transmission communities where there is substantial recent in-migration of men and women seeking work. Such programmes have recently been initiated by a private/public/NGO partnership.     

High-risk sexual behavior at social venues in Madagascar

BACKGROUND: Persistent high levels of sexually transmitted infection (STI) in Madagascar indicate current prevention strategies are inadequate. STI/HIV prevention based in social venues may play an important role in reaching individuals at risk of infection. We identified venues where people meet sexual partners and measured the need and potential for venue-based prevention. METHODS: Interviews were conducted in 7 Madagascar towns with 1) community informants to identify social venues, 2) individuals socializing at a sample of venues to assess sexual behavior among venue patrons, and 3) venue representatives to assess the potential for venue-based intervention. RESULTS: Community informants identified numerous venues (range: 67-211 venues, depending on the town); streets, bars, and hotels were most commonly reported. Among 2982 individuals socializing at venues, 78% of men and 74% of women reported new sexual partnership or sex trade for money, goods, or services in the past 4 weeks and 19% of men and 18% of women reported symptoms suggestive of STI in the past 4 weeks. STI symptom levels were disproportionately high among respondents reporting either sex trade or new sexual partnership in the past 4 weeks. Twenty-eight percent of men and 41% of women reported condom use during the last sex act with a new partner. Although 24% to 45% of venues had hosted STI/HIV interventions, interventions were deemed possible at 73% to 90% venues according to 644 interviews with venue representatives. CONCLUSIONS: Venue-based intervention is possible and would reach a spectrum of populations vulnerable to STI/HIV including sex workers, their clients, and other high-risk populations.     

HIV, the clustering of sexually transmitted infections, and sex risk among African American women who use drugs

African American women have high rates of most sexually transmitted infections (STIs), including HIV. STIs have been associated with increased HIV transmission risk. METHODS: Two hundred twenty-eight black women who used drugs completed a structured questionnaire in a central Brooklyn, NY-based research center between March 2003 and August 2005. Women were screened for HIV, herpes simplex virus-2, syphilis, gonorrhea, chlamydia, and trichomoniasis. This analysis determined if STIs cluster within individuals and if clustering and sex practices or partnerships differ by HIV status. RESULTS: Thirty-eight (17%) women tested HIV seropositive and STI prevalence was herpes simplex virus-2 (79%), trichomoniasis (37%), chlamydia (11%), and gonorrhea (2%). Few women knew themselves to be infected with STIs other than HIV. Excluding HIV, the mean number of STIs per woman was 1.3 (SD 0.7). HIV-infected women were significantly more likely than uninfected women to have multiple positive screens (1.6 vs. 1.2, P = 0.002). Women reported having both lower and higher risk sex partners. HIV-infected women were 2 times more likely than uninfected woman to report current sex work (P = 0.05), the only difference in sex risk. In a linear regression model, crack cocaine use was uniquely associated with multiple positive STI screens, excluding HIV (P = 0.002). CONCLUSIONS: Several STIs, including HIV, seem to be endemic among black women who use drugs in this community. In addition to the known geographical clustering of HIV and STIs, STIs were also found to cluster at the individual level. Multiply STI infected individuals may unknowingly, but efficiently, contribute to high STI and HIV rates.     

Gender differences in the prevalence of sexually transmitted infections and genital symptoms in an urban setting in southern India

OBJECTIVES: To examine gender differences in sexual behaviour, the prevalence of laboratory-detected sexually transmitted infections (STIs) and self-reported genital symptoms in urban Chennai, Tamil Nadu, India. STUDY DESIGN: The data were based on a cross-sectional survey (n = 1649) of residents from low-income communities in Chennai. Data were collected during community-wide health camps comprising physical examinations, interviews and laboratory testing between March and June 2001. RESULTS: The population was young, sexually active, with a low prevalence of STI. The most commonly detected STI was Herpes simplex virus type 2 (HSV2; 13.2%). Women had a higher prevalence of HSV2, but were more likely than men to be asymptomatic. Most of the self-reported genital symptoms could not be linked to a laboratory-detected STI. >10% of the cohort had a history of an ulcerative STI and >5% had an inflammatory STI. CONCLUSIONS: Given a high prevalence of HSV2 in the study population, interventions targeting HSV2 transmission may be particularly relevant for this population.     

The association between abuse in childhood and STD/HIV risk behaviours in female genitourinary (GU) clinic attendees

OBJECTIVES: To compare and contrast women with a history of child abuse with those who have no history of child abuse on STI/HIV risk behaviours and safer sex beliefs in an inner city UK sample. DESIGN: Cross sectional sample survey. METHODS: Routine female clinic attendees were invited to complete an anonymous self report questionnaire which included background information, sexual and drug risk behaviour, self reported sexually transmitted infections (STIs), psychological distress (Hospital and Anxiety Depression Scale; HADS), Sexual Risk Cognitions Questionnaire (SRCQ), and history of child sexual, physical, and emotional abuse. RESULTS: 137 (45%) of 303 women reported a history of child abuse; all three forms of child abuse--sexual (26%), physical (20%), and emotional (27%) abuse--overlapped. The majority of women reported one sexual partner in the past month, and the majority did not use condoms. Women reporting a history of child abuse were more likely to have had previous STIs (p = 0.007) and to have had more than one STI (p = 0.04) compared with women who had not experienced child abuse. Injecting drug use and commercial sex work were of low prevalence across the whole sample and no group differences were found. Women reporting a history of child abuse had higher HADS anxiety (p = 0.03) compared with women with no history of child abuse. Confidence in using condoms with a sexual partner was not related to child abuse. Women with a history of child abuse reported significantly higher frequency of thoughts reflecting anticipated negative reactions from partners to suggesting condom use (p = 0.02) and judging a partner's risk by their appearance (p = 0.05) compared with women with no history of child abuse. CONCLUSIONS: Comparable rates of child sexual abuse with US studies were found in this UK inner city population of women attending sexual health services. Women who had experienced child abuse were more likely to report ever having had an STI and having had more than one STI. Complex psychological and social factors contribute to difficulties for women in negotiating safer sex including emotional distress, abuse histories, and anticipating a negative reaction from partners. Multifaceted prevention models are needed.     

Sexual risk factors among self-identified lesbians, bisexual women, and heterosexual women accessing primary care settings

OBJECTIVES: There is scant data on the sexual behaviors of women of diverse sexual orientations in a low-risk population. GOALS: The goals of this study were to sample women of all sexual orientations in primary care settings and to evaluate sexual behaviors and risk for HIV and other sexually transmitted diseases (STDs). STUDY: A total of 1,304 women (self-identified as 49% heterosexual, 11% bisexual, and 40% lesbian) were surveyed by anonymous questionnaire at 33 healthcare sites. RESULTS: Among women who recently had sex with men (N = 600), 51% reported ever using condoms. Heterosexual women were at highest risk for acquiring HIV as a result of lack of condom use (P <0.001), particularly in higher-risk situations. Bisexual women reported substance use with sex at a higher rate than lesbians or heterosexual women (P <0.001). Lesbians had higher rates of sex with bisexual men (P <0.001) and injection drug users (P <0.02), but also a higher rate of condom use (P <0.001) compared with bisexual or heterosexual women. CONCLUSION: Women of all sexual orientations, and particularly heterosexual women, engaged in behaviors that put them at risk for HIV and STD.     

Sexually transmitted infections in women who have sex with women

OBJECTIVES: To describe the prevalence of sexually transmitted infection (STIs) in a sample of women who have sex with women (WSW) and to identify risk factors for the acquisition of STI. METHOD: Cross sectional survey. Questionnaire for demographic, sexual history, and sexual practice data linked with the results of genitourinary examination. 708 new patients attending two sexual health clinics for lesbians and bisexual women in London were surveyed. RESULTS: A majority of WSW reported sexual histories with men (82%). Bacterial vaginosis and candida species were commonly diagnosed (31.4% and 18.4% respectively). Genital warts, genital herpes, and trichomoniasis were infrequently diagnosed (1.6%, 1.1%, and 1.3% respectively). Chlamydia, pelvic inflammatory disease, and gonorrhoea infections were rare (0.6%, 0.3%, and 0.3% respectively) and diagnosed only in women who had histories of sex with men. CONCLUSIONS: Although we have demonstrated a low prevalence of STI, WSW may have sexual histories with men as well as women or histories of injecting drug use, and are therefore vulnerable to sexually transmitted or blood borne infections. Diagnosis of trichomoniasis, genital herpes, and genital warts in three women who had no history of sex with men implies that sexual transmission between women is possible.     

Sexually transmitted infections in Bangladeshis resident in the UK: a case-control study

OBJECTIVE: To evaluate the prevalence of sexually transmitted infections (STIs) and mode of presentation in patients originating from Bangladesh and resident in the United Kingdom in comparison with non-Bangladeshi patients attending an inner London genitourinary medicine (GUM) clinic. METHODS: A retrospective, cross sectional study with comparator group was carried out at an open access GUM clinic in east London. 104 consecutive newly attending Bangladeshi men were compared with 199 consecutive newly attending non-Bangladeshi men and 115 consecutive newly attending Bangladeshi women were compared with 218 consecutive newly attending non-Bangladeshi women. Any diagnosed sexually transmitted infections, sexual history characteristics, reasons for presentation, and referral patterns were noted. RESULTS: Bangladeshi men (28.8% compared with 7.5%; p<0.0001) and women (42.7% compared with 12.8%; p<0.0001) were more likely to be referred by their general practitioners or other medical services. Bangladeshi men were more likely to present with sexual dysfunction (12.5% compared with 2.5%; p=0.001). The prevalence of STIs was broadly similar across the study groups; however, syphilis was significantly more common in the Bangladeshi men (10.9% compared with 4%; p=0.04) and nongonococcal urethritis (NGU) in the control men (35% compared with 20.2%; p=0.02). Bacterial vaginosis was an infrequent diagnosis in the Bangladeshi women (3.5% compared with 22.4%; p<0.0001). CONCLUSIONS: STI prevalence in Bangladeshis attending GUM services is similar to other populations although patterns of presentation and referral do show variation. Bangladeshi men are more likely to access GUM clinics for psychosexual services. The presence of STIs in Bangladeshis particularly those imported from Bangladesh provides an opportunity for HIV transmission between the United Kingdom and Bangladesh.     

Sexually transmitted infections and reproductive health in Azerbaijan.

BACKGROUND: Little is known about the prevalence of sexually transmitted infections (STIs) and about sexual and reproductive health in Central and Eastern Europe. However, it is clear that major epidemics of STIs currently exist. GOAL: To provide baseline information for the development of national guidelines on the management of STIs in Azerbaijan. STUDY DESIGN: A prevalence study on STIs, including a questionnaire on sexual and reproductive health, in two regions of Azerbaijan targeted three groups: (1) pregnant women, (2) gynecology patients, and (3) men attending a dermatovenereology clinic. RESULTS: The 407 pregnant women in this study had a mean of 1.47 abortions and 1.40 births per woman. Of these women, 12% reported condom use and 41% previous symptoms of a sexually transmitted infection. Active syphilis was found in 1.7% of the women. The 326 gynecology patients had a mean of 2.54 abortions and 2.63 births per woman. Of these patients, 11% reported use of modern contraceptives, 18.3% previous condom use, and 63% previous symptoms of an STI. The prevalence of active syphilis was 2.2%, Chlamydia trachomatis 3.1%, Neisseria gonorrhoeae 2.8%, Trichomonas vaginalis 7.1%, Candida 33.1%, and bacterial vaginosis 32.5%. Of the 197 male patients, 67% reported multiple partners in the past 3 months, 62% money exchanged for sex, 37% condom use ever, and 40% a history of STIs. Active syphilis was found in 9.5% of the men, C trachomatis in 5.9%, N gonorrhoeae in 17%, and T vaginalis in 4.4%. CONCLUSIONS: The data show high-risk behavior in the men attending STI clinics, poor sexual and reproductive health status in the women, and underreporting of official data.     

HIV and STIs in clients and female sex workers in mining regions of Gejiu City, China

OBJECTIVE: To investigate HIV/sexually transmitted infections (STIs) among female sex workers (FSWs) and clients in a mining region of China. GOAL: To estimate HIV/STI prevalence and to identify HIV risk factors among FSWs and miner clients. STUDY DESIGN: A cross-sectional study of 96 FSWs and 339 miner clients. RESULTS: In FSWs, prevalence of HIV was 8.3%, herpes simplex virus-2 70.8%, syphilis 12.5%, Neisseria gonorrhoeae 36.8%, Chlamydia trachomatis 46.3%, Trichomonas vaginalis 22.1%, and 90.6% were infected with any STI. Illegal drug use was associated with HIV [adjusted odds ratio (OR) = 45.1, 95% confidence interval, 6.4-317.9] in FSWs, and 45.8% reported no condom use with the last client. In miner clients, HIV prevalence was 1.8%, herpes simplex virus-2 14.9%, syphilis 2.4%, N. gonorrhoeae 2.1%, C. trachomatis 6.5%, and 23.2% were infected with any STI. Never using condoms with FSWs and regular partners were reported in 61.2% and 84.1%, respectively. Independent risk factors for HIV in miner clients were illegal drug use (OR 190.2), symptoms of urethral discharge or frequent urination (OR 32.9), early sexual debut (OR 7.1), and visiting 4 or more FSWs in the last 12 months (OR 11.5). CONCLUSIONS: HIV/STI prevalence is high among FSWs and moderate among clients in mining regions of Gejiu City. Drug use is the most important factor placing FSWs and miner clients at risk for HIV in Gejiu City; risky sexual characteristics such as early sexual debut, frequent visits to FSWs, and STI symptoms are also important factors for miner clients. FSWs and miner clients may constitute bridging groups for HIV to low-risk populations.     

A national survey of clinic sexual histories for sexually transmitted infection and HIV screening

BACKGROUND: Optimal elements of a sexual history for sexually transmitted infection (STI) and HIV risk assessment remain undefined. GOAL: The goal of this study was to describe sexual histories in use at STI clinics across the United States. STUDY: This study consisted of a cross-sectional survey of facilities in cities with populations >200,000 (n = 65). Within each city, a public health STI clinic (71% of the sample) or other STI care facility (29%) was randomly selected and sexual history forms were requested. Information was obtained from 48 clinics (74% response). RESULTS: Most forms recorded information on symptoms and prior STI (96%), condom use (88%), other contraception (85%), and numbers and gender (83%) of sex partners. Common HIV risk questions were injecting drug use (IDU; 94%), sex for drugs or money (58%), and sex with an HIV-positive or IDU partner (52%). Ascertainment of time during which risks occurred (contact periods) varied from the past 14 days to the past 12 months, with only 38% of clinics using any 1 time period. Few histories (17%) incorporated questions for men who have sex with men (MSM). Only 2 (4%) had space to record information about sexual behaviors by the HIV status of the sex partner. Condom use was infrequently assessed specifically for vaginal and anal sex (13%), and condom use problems were rarely explored (10%). Most forms documented STI/HIV counseling, although few (25%) included specific risk reduction plans. CONCLUSIONS: Sexual histories are highly variable. Although challenging to accomplish, STI/HIV care, surveillance, and prevention may be improved by developing consensus on core questions to be used in sexual histories.     

Assessing the impact of national anti-HIV sexual health campaigns: trends in the transmission of HIV and other sexually transmitted infections in England

OBJECTIVE: To assess the impact of the sexual component of AIDS and HIV campaigns on transmission of HIV and other sexually transmitted infections (STIs). DESIGN: Comparison of time series data. SETTING: England, 1971-1999. OUTCOME MEASURES: HIV transmission and diagnoses among men who have sex with men (MSMs), rates of attendances and specific STI diagnoses (per 100 000 total population) at genitourinary medicine (GUM) clinics. RESULTS: Awareness of AIDS and campaigns in 1983-4 among homosexual men coincided with substantial declines in transmission of HIV and diagnoses of syphilis among MSMs. During general population campaigns in 1986-7 new GUM clinic attendances requiring treatment fell by 117/10(5) in men and 42/10(5) in women. Rates for gonorrhoea fell by 81/10(5) and 43/10(5) and genital herpes by 6/10(5) and 4/10(5), respectively. Previous rises in genital wart rates were interrupted, while rates of attendances not requiring treatment (the "worried well") increased by 47/10(5) and 58/10(5) for men and women, respectively. Since 1987 diagnoses of HIV among MSMs have not declined, averaging 1300-1400 annually. Following a period of unchanging rates there have been substantial increases in GUM attendances requiring treatment, notably for gonorrhoea, syphilis, and viral STIs since 1995. CONCLUSIONS: Self help initiatives and awareness among homosexual men in 1983-4 contributed significantly to a fall in HIV transmission among MSMs, and the general campaigns of 1986-7 were associated with similar effects on all STI transmission. Both effects seem to have occurred through changing sexual behaviour, and probably contributed to the UK's low national HIV prevalence. Bacterial STI incidence has increased significantly since 1995 and there is no evidence that recent prevention initiatives have reduced HIV transmission among MSMs, hence sexual health initiatives need to be comprehensively reinvigorated in England.     

Reported sexually transmitted infections in Swedish Internet-using men and women

Although the Internet has become a forum for making sexual contacts, and has been associated with increased sexually transmitted infection (STI) transmission, we have little information of history of STIs in Internet‐based samples. The Internet behaviours that are associated with STI acquisition are poorly understood. We analysed STI histories reported by 904 Swedish men and 931 Swedish women who responded to an Internet‐based survey on sexual behaviour in 2002: 16.6% of men and 22.5% of women reported a lifetime history of STIs, with Chlamydia being the most common for both genders. 3% of men and 5% of women who reported an STI, indicated that they had had more than one. Sources of the STI, where known, were Internet‐acquired partners in only 3% of cases. There were no differences between men and women with or without an STI history regarding the kind of online sexual activities they engaged in, how they found sexual material online, and the reasons they engage in sexual activities. These rates are similar to those reported in a national random study of sexuality in Sweden. Contrary to prior research, these results suggest no relationship between STI and specific Internet characteristics usage patterns. These data suggest that the Internet is not yet a major source of STIs in Swedish men and women. Given these STI histories, the Internet may be a useful medium to include in STI prevention efforts.     

Data from UK genitourinary medicine clinics, 2006: a mixed picture

OBJECTIVE: To give an overview of the latest latest trends in diagnoses made and services provided by genitourinary medicine (GUM) clinics in the UK. METHODS: Aggregate data collected from the KC60 statistical returns for GUM clinics in England, Wales and Northern Ireland and disaggregate data collected using the STI Surveillance System for GUM Clinics in Scotland. These data were collated and numbers of diagnoses were adjusted for missing clinic data. RESULTS & CONCLUSION: Overall, numbers of new diagnoses of sexually transmitted infections (STIs) continued to rise in 2006. However, there was some evidence of improvement, with new diagnoses of gonorrhoea falling for the fourth successive year. Chlamydia continued to be the most common STI diagnosed in GUM clinics, and the sharp rise in new diagnoses over the last 10 years was most likely associated with an increase in testing volume and accuracy. The highest rates of STI diagnoses continued, in the main, to be among 16-24-year-olds, and there were some notable rises among this age group also: new diagnoses of genital herpes in teenage women rose by 16% in 2006. Improving the sexual health of men who have sex with men (MSM) must remain a priority, as the increase in numbers of new STI diagnoses among MSM over the past 10 years continued unabated into 2006. However, despite facing the challenge of reducing patient waiting times, there has been a considerable rise in sexual health screens and HIV tests being provided by GUM services, and this could, if sustained, result in significant improvements in sexual health in the coming years.     

Psychosocial predictors of HIV/STI risk behaviours in a sample of homosexual men

OBJECTIVES: To determine the prevalence of STI/HIV risk behaviours in a sample of homosexual men and investigate the psychosocial and cognitive variables associated with these behaviours. METHOD: A sample of 123 users of a homosexual men's sexual health clinic completed a questionnaire which included demographic information, psychometric measures, history of sexual risk behaviour, and history of non-consensual sex (NCS). RESULTS: High rates of sexual risk were found in this sample behaviour (36% of men had risky sex in the previous month) despite using a narrower definition than other recent studies. Comparable rates of non-consensual sex were found in this sample (26% of the sample had experienced NCS); however, this variable was not directly linked to increased risk behaviour. Depression and cognitions associated with controllability or predictability of risk were associated with increased HIV/STI risk behaviour. CONCLUSIONS: Clinical measures of depression are associated with risk behaviour in this sample as are cognitions about the uncontrollability of risk and reducing chances of exposure to HIV by insertive sexual practices and fidelity. Demographic variables, a history of non-consensual sex and depression are not predictors of risk behaviour when sexual risk cognitions are used to predict unsafe sexual practices indicating that cognitions are foremost in driving risk behaviours, demographic variables, and the NCS history of the subject. Given the considerable costs of providing medical care to patients with HIV it is likely that even modest reductions in rates of HIV infection through proactive psychological interventions to modify erroneous cognitions will prove highly cost effective.
