A substantial minority of HIV-infected Australians are not taking antiretroviral drugs. This study investigated the reasons behind their decision not to do so. Anyone who was HIV-infected but not taking antiretroviral drugs could participate. A self-administered, anonymous questionnaire was used, the principal recruitment method being through insertion of the questionnaire into gay community newspapers in Sydney and Melbourne. All respondents were asked questions covering demographics, previous AIDS-defining illnesses, T-cell and viral load monitoring, and previous use of antiretroviral drugs. In addition, respondents who had considered going on antiretroviral treatment, but then decided not to do so, were given a list of possible reasons for their decision and asked to indicate how much each played a role in their thinking. Of the 270 respondents, the great majority were gay men. One-eighth had experienced AIDS-defining illnesses. Two-thirds had recently had T-cell and viral load tests. One-third had taken antiretroviral drugs previously. Over two-thirds had considered antiretroviral therapy, most having given the matter quite some thought. Reasons for not taking up therapy did not differ greatly at different stages of HIV disease. The most common individual reason was fear of side effects. Important themes that emerged from factor analysis of the reasons data included distrust of conventional medical approaches to treatment, practical problems associated with taking antiretroviral drugs, unpleasant thoughts that being on therapy would evoke, and acceptance of the idea of dying. The findings can be used by doctors and counsellors to help patients clarify and evaluate their concerns about antiretroviral therapy.

The aim of this study was to estimate the level of knowledge about sexuality, attitudes and sexual behaviour of female adolescents. The study included 194 female students, 117 from Medical High School (MHS) and 77 from General High School (GHS) in Zagreb. Data was collected using an anonymous self-administered questionnaire. In addition to items on personal data (age, parental education etc.), the participants were asked to define terms about sexuality (e.g. menstruation, puberty) the definitions of which are found in biology textbooks for the fifth and eighth grade of primary school. The aim of the third part of the survey was to collect information about attitudes and behaviour of female adolescents. The results showed a low level of knowledge in students of both schools. General High School students showed a higher level of knowledge than their Medical High School peers. One fifth of General High School students and 1/3 of Medical High School students were unable to define the term "menstruation". The majority of adolescents talk about sexuality with their friends, 92.1% of General High School and 81.2% of Medical High School students. Almost 50% of students of both schools would like to talk about sexuality with their school doctor. 6.9% of Medical High School students had at least one sexual intercourse while none of the General High School students had been sexually active at the time of the survey. As the majority of students were not sexually active and results showed a rather low level of knowledge, this seems to be the ideal period for the implementation of educational programs aimed at increasing the level of knowledge, and thus preventing unwanted consequences (STD, pregnancy, abortion, infertility).

We aimed to identify risk factors associated with delayed diagnosis of HIV infection in a French region highly affected by AIDS. Data were collected in southeastern France through the HIV-surveillance system based upon anonymous declarations by laboratories and physicians prescribing HIV testing. From January 1996 to December 1997, 825 persons were diagnosed for the first time as HIV infected (female: 32%; >40 years: 28%); 46% had been infected through heterosexual intercourse, 26% through homosexual intercourse, and 19% through intravenous drug use. The semestrial (6 monthly) incidence rate decreased from 122.7 to 69.7 per million inhabitants (P<0.001). County of residence, age, sex, country of birth, and transmission category did not change significantly during the observation period. Twenty-seven per cent had a delayed diagnosis of HIV infection. This proportion did not differ significantly according to sex or country of birth, or during the observation period. However, after controlling for the other factors, delay was more frequent among injecting drug users (IDUs) (35%, P<10(-2)) than other transmission categories; it was also positively associated with age (47% above 50 years vs 13% under 30 years, P<10(-2)). This study highlights that, in spite of the current AIDS prevention policy and wide access to HIV screening, the proportion of delayed diagnosis of HIV infection remains high. Physicians should concern themselves with this public health issue, and campaigns should target people insufficiently aware, especially IDUs and older people. Further research is needed to understand better the causes of delayed diagnoses and of inequalities in access to HIV screening.

Our objective was to identify barriers to the use of genitourinary medicine (GUM) services for off-street female sex workers in a provincial city, using self-administered anonymous questionnaires distributed to premises during outreach sessions by a clinic health adviser. Questionnaires were completed by 85 (56%) of the estimated 150 women working in the 13 targeted premises. The main obstacles to service use were the length of time spent in clinic (83%), dislike of needles (28%), difficulty getting to clinic (18%) and dislike of examinations (16%). The majority (71%) rejected sex worker-only sessions. Women using the local service, which provided outreach sessions, were more likely to have disclosed their occupation to the service (82% vs 36%; P=0.035). GUM clinics may optimize their accessibility to sex workers by minimizing the time required per visit, and introducing non-invasive screening methods where possible. Outreach visits by clinic staff may encourage women to disclose their occupation, enabling them to assess vaccinations for hepatitis B.

To document knowledge and attitudes regarding sexuality and sexual practices of male adolescent high school students in Lima, Peru, a self-administered, anonymous survey was completed by 991 male adolescents aged 12-19 as part of a School-Based Sex Education Intervention model. Questions concerned sociodemographic information; family characteristics; personal activities; knowledge and attitudes regarding sexuality; sexual experience; and contraceptive use. Knowledge related to sexuality was limited. Males tended to mainly discuss sexuality with their male peers (49.8%). Attitudes towards sexual activity and condom use were largely positive, although some males expressed ambivalent feelings towards the latter. Of the sample, 43% had ever had sex; age at first sexual intercourse was 13 years. While 88% of the sample would use condoms, 74% also gave reasons for not using them. Sexual activity was related to age, ever having repeated a grade, living with only one parent or in a mixed family, activities such as going to parties, use of alcohol, tobacco, and drugs, and viewing pornographic videos or magazines. Many male adolescents were at risk of causing an unintended pregnancy or acquiring an STD.

Our objective was to compare the utilization of healthcare/support services for people with HIV infection in Europe. Between August 1996 and September 1997 self-administered anonymous questionnaires were distributed by reference HIV treatment centres and HIV support organizations. The questionnaire was completed by 1366 people living with HIV/AIDS. A small number of people had received influenza or pneumococcal vaccinations (34% and 19% respectively). Many patients did not receive dental care (48% of participants from the southern countries) and only 72% of the women had a gynaecological examination. More participants from the south reported insufficient access to healthcare/support services, particularly for nursing care (19%), psychological support (33%), nutritional advice (45%), access to support organizations (36%), and legal advice (46%). In conclusion, many people living with HIV/AIDS in Europe do not benefit from certain annual medical procedures proposed by international guidelines and consider themselves to have insufficient access to health/support services.

Our objective is to gauge the prevalence of hepatitis C virus (HCV) antibodies among a population at risk of contracting sexually transmitted infections (STIs) and, thus, the efficiency with which the virus is transmitted sexually. The investigators undertook an unlinked anonymous HCV antibody testing study of residual syphilis serology specimens taken from attenders of genitourinary clinics in Glasgow, Edinburgh and Aberdeen during 1996/97. The results were linked to non-identifying risk information. Anti-HCV prevalences among non-injecting heterosexual men and women, and non-injecting homosexual/bisexual males ranged between 0 and 1.2%; the only exception to this was a 7.7% (4/52) prevalence among homosexual/bisexual males in Aberdeen. The overall anti-HCV prevalence for homosexual/bisexual males was 0.6% (4/668), for heterosexual males 0.8% (32/4135), for heterosexual females 0.3% (10/3035) and for injecting drug users 49% (72/148). Only 3 (all female) of the 46 non-injectors who were antibody positive were non-UK nationals or had lived abroad. HCV antibody positive injectors were less likely to have an acute STI and more likely to know their HCV status than non-injectors; no differences in these parameters were found between positive and negative non-injectors on anonymous HCV antibody testing. Our findings are in keeping with the prevailing view that HCV can be acquired through sexual intercourse but, for most people, the probability of this occurring is extremely low. Interventions to prevent the spread of HCV should be targeted mainly at injecting drug user (IDU) populations.

The objectives of this paper were to examine changes in AIDS/STD knowledge and behaviour from 1992-1998, current levels of STD infection and psychosocial and demographic determinants of condom use and STD infection among female sex workers. Data for the study were drawn from cross-sectional surveys of female sex workers conducted in 1992, 1994 and 1997-8. For each survey, women participated in a face-to-face interview in the brothel complexes. Survey questions included information on AIDS/STD knowledge, demographics, sexual history and psychosocial factors related to condom use. After the last survey, women were offered a vaginal exam for STD diagnosis and treatment. Sera were tested for HIV infection (anonymous, Elisa/Western blot) and syphilis (TYPHA, RPR). Cervical mucous was tested for chlamydia (LcX), gonorrhea (LCx), herpes (pcr) and HPV (pcr). Knowledge of AIDS and awareness of STDs has increased tremendously in this population since 1992. Reported condom use has also increased substantially (69.9%). Perceived susceptibility toward HIV infection remains low. Ineffective preventive strategies such as medication use continue to be common. HIV infection remains very low in this population (0.2%), although the prevalence of other STDs such as gonorrhea (60.5%), chlamydia (41.3%) and HPV (37.7%) were very high. STD knowledge and self-efficacy were significantly related to condom use as were the sex workers' perceived susceptibility to STD and HIV infection. Women with a larger number of partners were more likely to be infected with gonorrhea, chlamydia and HIV. Women who had come to Bali recently were more likely to be infected with HIV and gonorrhea.

This paper presents a novel method for assessing patients' perceptions of empowerment in the context of drug therapy, the Treatment-related Empowerment Scale (TES). The 10-item TES was specifically constructed to address components of communication, treatment choice, decision-making and satisfaction. Evaluation of the scale in a cross-sectional anonymous survey of 43 patients with advanced HIV infection revealed acceptable internal reliability (Cronbach's alpha=0.85) and evidence of both criterion and discriminant validity. Patients who perceived a high degree of treatment-related empowerment were less likely to view doctors as overly reliant on prescribing medicines and reported lower rates of intentional noncompliance. The TES has scope as a concise measure of patients' degree of control over the selection and use of drug therapy, and may be of particular value for current combination therapy regimens.

In recent years an increasing number of antiretrovirals have become available. In order to define the optimal treatment regimens an increasing number of clinical trials are needed. Our objective was to study the profile of participants in HIV clinical trials in Europe and learn from their experience and views. Between August 1996 and September 1997, self-administered anonymous questionnaires were distributed to people with HIV infection at inpatient and outpatient clinics in 11 European countries. One thousand three hundred and sixty-six people completed the questionnaire (50% response rate). Four hundred and twenty (31%) of the respondents reported that they had previously participated in at least one HIV clinical trial. The percentage of people who had taken part in a clinical trial varied widely between the different centres, from 12% in Athens to 61% in Antwerp and Brussels. A significantly higher participation rate was observed in the northern and central part of Europe compared with the south (respectively 40% vs 18%) and also among people with a higher income. Most people (92%) stated that they were 'well' or 'very well' informed prior to enrolment in the trial. However, 4% reported that they had not given written approval and 22% felt that they were pushed into participating. Only 21% stated that they were informed about the outcome of the study on its completion. The most important reason for non-participation (37% of the non-participants) was because a clinical trial had never been proposed. In conclusion, a majority of people with HIV infection in European HIV treatment reference centres were willing to participate in clinical trials. HIV clinical trials in Europe should adhere more strictly to universal ethical standards.
