Attitude of pregnant women towards HIV testing in Abidjan, C?te d'Ivoire and Bobo-Dioulasso, Burkina Faso. DITRAME Study Group (ANRS 049 Clinical Trial). Diminution de la Transmission Mère Enfant du VIH. Agence Nationale de Recherches sur le SIDA

OBJECTIVE: To evaluate the attitude of pregnant women towards HIV testing in two cities of West Africa: Abidjan, C?te d'Ivoire and Bobo-Dioulasso, Burkina Faso. METHODS: In the context of a clinical trial to prevent HIV vertical transmission, HIV counselling and testing was offered systematically to women attending antenatal clinics. Informed consent was obtained and test results were given anonymously. Multiple logistic regression was performed to identify factors associated with refusal for testing and failure to return for test results. RESULTS: A total of 9724 pregnant women were interviewed from January 1995 to September 1996. In Abidjan (n=5766) and Bobo-Dioulasso (n=3958), 78 and 92.4% of the women consented to HIV testing, respectively, and 58.4 and 81.8% of them returned for the test results disclosure, respectively. In the two sites, the counsellors themselves and high educational level of the women appeared to be related to refusal of the test, whereas last trimester gestation was associated with failure to return for test results. In Abidjan, foreigners and employees were more likely to refuse testing, and HIV-infected women were three times less likely to return for results than uninfected women. CONCLUSION: Future implementation of interventions to reduce vertical transmission of HIV that require antenatal HIV testing and counselling will have to solve issue of acceptability of HIV testing by pregnant women.     

Antenatal HIV antibody testing in Australia

OBJECTIVE: To evaluate the role of voluntary antenatal testing in HIV surveillance and prevention by examining antenatal HIV antibody testing practice and policy in Australia. DESIGN: Cross-sectional study using a self-administered questionnaire. SUBJECTS AND SETTING: Specialist obstetricians and gynaecologists and general practitioners (GPs) affiliated with the Royal Australian College of Obstetricians and Gynaecologists and Australian public hospital antenatal clinics, August-November 1992. MAIN OUTCOME MEASURES: The percentage of public hospital antenatal clinics and specialist and GP obstetricians in Australia who tested pregnant women for HIV antibody as part of their antenatal care, and the proportion of pregnant women in Australia who had an antenatal HIV antibody test in the 1991-92 financial year. RESULTS: Questionnaires concerning antenatal HIV antibody testing were completed by 90% (993/1108) of specialists, 87% (2134/2461) of GPs and 93% (215/230) of public hospitals surveyed. Of the 706 specialists and 1503 GPs who reported that they were currently engaged in obstetric care, approximately 60% (430/706) and 935/1503, respectively) offered antenatal HIV testing either to all pregnant women or to selected groups at risk. There were significant differences in testing patterns between States and Territories. For the 95 public hospitals with antenatal clinics, 81% (77) offered the HIV antibody test to all or selected groups of pregnant women; these percentages did not differ significantly between States and Territories. It was estimated that 25% of pregnant women seen by specialists, 29% seen by GPs and 9% seen in public hospital clinics were tested for HIV antibody as part of their antenatal care in 1991-92. CONCLUSIONS: In Australia approximately one in five pregnant women were tested for HIV antibody as part of their antenatal care in 1991-92. Voluntary HIV testing in pregnancy may provide unrepresentative data for measuring the prevalence of HIV infection in pregnant women.     

Sequence analysis of genes encoding rodent homologues of the human tumor-rejection antigen SART-1

OBJECTIVE: To assess pregnant women's knowledge of, and attitudes towards, antenatal HIV testing, and its acceptability to them. SETTING: Antenatal clinic at Guy's Hospital, London, six community antenatal clinics and a midwifery group practice. POPULATION: Eight hundred and forty-three women attending the antenatal clinics. METHOD: The women received a leaflet explaining HIV testing, and completed a questionnaire before and after their booking appointment. This included an assessment of their knowledge of, and attitudes towards HIV testing, and its acceptability. RESULTS: Seven hundred and eighty-nine women (94%) completed questionnaires. Fifty-one percent (n = 405) were Caucasian, 25% (n = 195) African, 11% (n = 86) West Indian and 13% (n = 100) were from other ethnic groups. Fifty-eight percent received the HIV information leaflet, of whom 86% had read it. Knowledge relating to HIV was good, the median knowledge score being 6 out of a possible 8, but it was less in non-Caucasian women and those with lower educational qualifications. Knowledge was not related to uptake of testing. Thirty-five percent of women accepted the offer of an HIV test, rates being higher in hospital clinics (41%) than in the midwifery group practice (10%) and the community clinics (30%). Women more likely to accept the offer of an HIV test were non-Caucasian (P = 0.0443), those who had thought about the HIV test before this pregnancy (P = 0.0298) and those seeing one particular midwife (P = 0.0003). Most women (67%) thought that all pregnant women should be offered the HIV test and then make their own decision. Overall, 64% women did not change their original pre-discussion decision on testing for HIV. Thirty-six percent of women changed their decision from 'yes' to 'no' or 'don't know' after seeing the midwife. Women attending the community clinics (P = 0.003) and those who had been tested before (P = 0.0451) were more likely to change their decision. CONCLUSION: This study, in a multiethnic population, has shown that knowledge regarding HIV is good but does not increase the uptake of testing. Women prefer to be offered the HIV test and make their own choice regarding whether to accept it.     

Change in sexual behaviour and decline in HIV infection among young pregnant women in urban Uganda

OBJECTIVE: To describe sexual behaviour that may partly explain a decline in HIV seroprevalence in pregnant women in urban settings in Uganda, East Africa. SETTINGS: Two major urban districts in Uganda. METHODS: Repeated population-based behavioural surveys in 1989 and 1995, and repeated HIV serological surveys in consecutive pregnant women attending antenatal clinics from 1989 to 1995. RESULTS: During the study period, a 2-year delay in the onset of sexual intercourse among youths aged 15-24 years and a 9% decrease in casual sex in the past year in male youths aged 15-24 years were reported. Men and women reported a 40% and 30% increase in experience of condom use, respectively. In the same study area, over the same period, there was an overall 40% decline in the rates of HIV seroprevalence among pregnant women attending antenatal clinics. It can be hypothesized that the observed declining trends in HIV correspond to a change in sexual behaviour and condom use, especially among youths. CONCLUSIONS: This is the first report of a change over a period of 6 years in male and female sexual behaviour, assessed at the population level, that may partly explain the observed decline in HIV seroprevalence in young pregnant women in urban Uganda. This result should encourage AIDS control programmes to pursue their prevention activities.     

Lactic dehydrogenase virus infection enhances parasite egg production and inhibits eosinophil and mast cell responses in mice infected with the nematode Nippostrongylus brasiliensis

OBJECTIVE: To determine if awareness of methods to reduce vertical transmission of human immunodeficiency virus (HIV) is associated with HIV test acceptance and to clarify patients' attitudes toward routine versus elective prenatal HIV testing. METHODS: In a cross-sectional study, 247 antenatal patients were surveyed regarding HIV knowledge, self-perceived HIV risk, and willingness to learn a positive test result. This information, along with demographic and risk factor data, was related to HIV test acceptance. Patients also indicated their attitudes toward routine versus elective prenatal testing for HIV and other common prenatal screening tests. RESULTS: Seventy-two percent of antenatal patients accepted HIV testing. Test acceptance was not associated with the presence of risk factors, self-perceived HIV risk, or demographic factors, including race and ethnicity. Test acceptance was associated positively with patients' knowledge of a medical intervention to reduce vertical transmission and their willingness to learn a positive HIV test result. Only 24% of patients knew that the risk of vertical transmission could be reduced using medication. Sixty-nine percent of patients said that prenatal HIV testing should be routine, whereas 27% said that it should be done only after specific written consent. As a group, our patients viewed HIV screening no differently from screening for other infections in pregnancy. CONCLUSION: Interventions aimed at increasing HIV testing rates among pregnant women should focus on educating patients about vertical transmission reduction and promising new therapies for HIV infection. Proponents of elective testing should re-evaluate the assumption that patients view HIV testing differently from other prenatal tests for which separate written consent is not required.     

Uptake of interventions to reduce mother-to-child transmission of HIV in the United Kingdom and Ireland

OBJECTIVES: To describe the uptake of interventions to reduce mother-to-child transmission of HIV infection. DESIGN: Voluntary confidential reporting of HIV infection in pregnancy and childhood; telephone interview with key professionals in all London maternity units. SUBJECTS AND SETTING: HIV-infected pregnant women and children in the United Kingdom and Ireland. MAIN OUTCOME MEASURES: Trends in breastfeeding, use of zidovudine, mode of delivery and terminations of pregnancy. RESULTS: Between 1990 and 1995, 14 (4%) out of 314 women diagnosed with HIV infection before delivery breastfed compared with 109 (77%) out of 142 diagnosed after delivery. Since 1994, zidovudine use has increased in each 6-month period (14, 39, 67, and 75%; chi 2 = 17.5, P < 0.001), although in 1995 it was the policy of only 48% of London maternity units to offer zidovudine to HIV-infected women. During 1995, 44% of HIV-infected women were delivered by elective Cesarean section. Since 1990, 20% of women first diagnosed in pregnancy were reported to have their pregnancy terminated. CONCLUSIONS: Although detection of previously undiagnosed HIV infection in pregnancy remains low in the United Kingdom, and particularly in London, HIV-infected pregnant women who are aware of their status are increasingly active in taking up interventions to reduce transmission to their infants. If all HIV-infected women attending for antenatal care in London consented to testing and took up interventions and termination of pregnancy at the rates observed in this study, the number of vertically infected babies born in London each year could be reduced from an estimated 41 to 13.     

HIV infection among pregnant women in Lindi, Tanzania, 1989-1993

One obstacle to contain the HIV-1 epidemic in the general population in Africa is a lack of knowledge about how it is spread in rural areas. We examined 683 pregnant women in 1989 and 484 in 1993 who attended antenatal clinics in Lindi district, Tanzania to determine changes in the prevalence of HIV-1 in a remote area in East Africa. The prevalence rose from 0.44% in 1989 to 8.7% in 1993. Women with more than 1 partner (17.25% vs 2.78%), STD patients (42.4% vs 6.2%), women from urban areas (10.2% vs 3.57%) and patients younger than 21 years were more likely to have HIV antibodies. By logistic regression analysis, 1993 as year of testing was associated with the greatest risk for HIV seropositivity (P < 0.00002) followed by clinical signs of STD (P < 0.00005) and urban residence (P = 0.0275). Teaching of all women attending antenatal care how to minimize their future risk of acquiring HIV is urgently needed as one tool to prevent a fast spread of HIV throughout the continent.     

Bicelles: a model membrane system for all seasons?

OBJECTIVES: To establish population-based HIV survey data in selected populations, and to assess the validity of extrapolation from HIV sentinel surveillance amongst antenatal clinic attenders (ANC) to the general population. METHODS: In a population survey, adults aged > or = 15 years were selected by stratified random cluster sampling (n = 4195). The survey was carried out in catchment populations of clinics used for national HIV surveillance. The methodology allows detailed comparisons of HIV infection patterns to be made in two areas (urban and rural). Whereas the sentinel surveillance used serum-based HIV testing, the population survey used saliva (93.5% consented to provide a saliva sample). RESULTS: Surveillance of ANC tended to underestimate the overall HIV prevalence of the general population, but differences were not statistically significant. In the urban area, the adjusted overall HIV prevalence rate of ANC (aged 15-39 years) was 24.4% [95% confidence interval (CI), 20.9-28.0] compared with 26.0% (95% CI, 23.4-28.6) in the general population. The respective rural estimates were 12.5% (95% CI, 9.3-15.6) versus 16.4% (95% CI, 12.1-20.6). Age-specific prevalence rates showed ANC to overestimate infection in teenagers (aged 15-19 years), whereas in the reverse direction of those aged > or = 30 years. Teenagers analysed by single year of age revealed both ANC and women in the general population with about the same steep increase in prevalence by age, but the former at consistently higher rates. Extrapolations might be biased substantially due to the higher pregnancy rates amongst uninfected individuals. CONCLUSIONS: ANC-based data might draw a rather distorted picture of current dynamics of the HIV epidemic. Even though representing an obvious oversimplification, extrapolations of overall prevalence rates may correlate with that of the general population.     

Disability, the risk of disability and changes in work capacity-- unacceptable conditions for insurance in occupational injuries and diseases

OBJECTIVE: To identify factors associated with failure to return for HIV post-test counselling in pregnant women in Kigali (Rwanda). SUBJECTS AND METHODS: In the context of a study on the impact of HIV infection on pregnancy, HIV-1-antibody testing was offered to all pregnant women attending the antenatal clinic of the Centre Hospitalier de Kigali from July 1992 to August 1993. Pre-test counselling was performed after verbal informed consent was obtained. Two weeks later, we formally enrolled all HIV-positive women and a corresponding number of HIV-negative women in a cohort. At this visit, post-test counselling was given to those wishing to be informed of their HIV serostatus. Level of knowledge about modes of HIV transmission and condom use were recorded. Four months after delivery, another interview was conducted to determine the proportion of women who used condoms regularly. RESULTS: A total of 1233 pregnant women were screened. The HIV seroprevalence was 34.4% [95% confidence interval (CI), 31.7-37.1]; 271 (63.9%) out of 424 HIV-positive and 577 (71.3%) out of 809 HIV-negative women asked for their HIV serostatus (P = 0.008). In multivariate analysis, the only variable significantly associated with failure to return for post-test counselling was a positive HIV test result (odds ratio, 0.7; 95% CI, 0.5-0.9; P = 0.009), independently of obstetrical history and socioeconomic characteristics. Among the 848 women who had post-test counselling, 50.9% of the HIV-positive women and 94.6% of the HIV-negative women stated that they planned to inform their partner of their serostatus (P = 0.0001). More than 95% of the women interviewed knew about sexual and parenteral transmission of HIV, but half were unaware of mother-to-child transmission. More than 80% of the women had seen a condom before, but 14% only had used it at least once. Among women who were sexually active 4 months after delivery, 8.8% of the HIV-positive and 3.9% of the HIV-negative women reported using a condom (P = 0.04). CONCLUSION: Innovative approaches for HIV testing and counselling programs are needed and the importance of psychosocial and cultural factors associated with HIV testing should be emphasized in African populations.     

Long-term effects of HIV counseling and testing for women: Behavioral and psychological consequences are limited at 18 months posttest.

Behavioral and psychological consequences of HIV counseling and testing (HIV C&T) for women were examined in a longitudinal, prospective study. Women who received HIV C&T at community health clinics (n?=?106) and a comparison group of never-tested women (n?=?54) were interviewed five times over 18 months. There was no change in risk behaviors as a consequence of testing: tested and untested women engaged in high-risk sexual behavior at baseline and 18 months later. Tested women reported more anxiety, depression, and intrusive thoughts about AIDS than did untested women. Although tested women were more concerned about AIDS, their potential risk factors over the study period generally were equivalent to those for untested women. HIV counseling and testing should be considered one aspect of a broader program of HIV prevention. Identification of alternative interventions must be a public health priority.

The relationship of HIV prevalence in pregnant women to that in women of reproductive age: a validated method for adjustment

OBJECTIVE: To devise and validate a method for adjusting HIV seroprevalences in pregnant women to estimate population prevalences among all women in their child-bearing years. DESIGN: Birth and termination rates from women with known HIV infection in the United Kingdom were calculated according to the likely route of HIV infection and whether HIV infection was diagnosed. METHODS: Birth and termination rates were weighted and combined to produce summary statistics. Comparisons were then made with population birth and termination rates to derive summary relative inclusion ratios (RIRs), the relative probabilities of including HIV-infected and uninfected women in seroprevalence surveys of pregnant women. RESULTS: The derived RIRs for women having live births were close to unity: 1.03 [95% confidence intervals (CI) 0.90-1.17] for London and 0.80 (Cl, 0.71-0.89) for elsewhere in England and Wales. This indicates that currently observed overall seroprevalences among pregnant women having live births in London would be similar to those among all women of the same age, while elsewhere it would be slightly underestimated. Sensitivity analysis indicated that RIRs could, however, vary three-fold (0.47-1.56) according to the proportion of diagnosed maternal infections and the mix of maternal HIV-exposure categories. The method was validated by using it to predict the ratio of unlinked seroprevalences between women having terminations and live births in London. It predicted a ratio of 1.74: 1, which is close to the observed ratio of 2.07 : 1. CONCLUSIONS: Application of HIV seroprevalences from pregnant women to whole populations may need adjustment for fertility rates among HIV-infected women. A general method for this has been derived and validated. Gathering fertility data for HIV-infected women is a useful adjunct to serosurveillance.     

Autopsy case report of a rare acute iatrogenic water intoxication with a review of the literature

This study provides survey data gathered from hospital-based paediatricians in New York City regarding several key issues in the diagnosis and treatment of paediatric AIDS. These include: perceived risk of acquiring HIV through professional exposure; referral patterns in the treatment of HIV-infected children; attitudes regarding the universal testing of pregnant women and newborns; willingness to raise prevention issues during health-maintenance visits, and interest in further AIDS education. Overall levels of perceived risk are quite high although unrelated to referral procedures. The modal procedure for both asymptomatic and symptomatic children is to treat in conjunction with a specialist, followed by referral to a specialist. The majority of respondents believe that all pregnant women seen in metropolitan clinics/hospitals should be routinely screened for HIV, but that newborn testing should be reserved for high risk babies. However, the vast majority believe that high risk newborns should be screened regardless of maternal consent. Physicians report strong support for the anticipatory guidance of adolescents, and an extremely high level of interest in continuing HIV/AIDS education for paediatricians.     

Phosphorylation of ATPase subunits of the 26S proteasome

OBJECTIVE: To evaluate the impact of the 1993 French National Policy which made it mandatory to offer screening for the presence of human immunodeficiency virus (HIV) to all pregnant women who planned to give birth, although women remained free to refuse the test. DESIGN: Successive surveys in April 1992 and May 1994 in south-eastern France. Logistic regressions were performed to identify factors which affected access to HIV testing for women who gave birth and those who terminated their pregnancy, and for each year of study. MAIN OUTCOME MEASURES: Attitudes and access to HIV testing among pregnant women, irrespective of pregnancy outcome. SETTING: All obstetrics and gynaecology departments and abortion clinics in the region. POPULATION: 3497 women in 1992 (2775 who were delivered and 722 who chose termination) and 3407 in 1994 (2701 who were delivered and 766 who chose termination). The response rates were 82% and 88%, respectively. RESULTS: In 1994 of women who were delivered, 73% had an HIV test, compared with 63% in 1992 (P < 0.001); however of women who terminated their pregnancy, only 28% had an HIV test, compared with 24.5% in 1992 (P not significant), although they were more at risk for HIV infection. Socioeconomic differences affecting access to testing were reduced between 1992 and 1994, but only among women who gave birth. CONCLUSION: Introduction of a policy which makes it mandatory to offer HIV screening to all women who intended to have their baby improved access to screening but did not improve the rate of preventative counselling. A mandatory requirement to offer HIV screening should be extended to women who request termination of pregnancy.     

HIV infection and HIV-1 clades among pregnant women in Harare, Zimbabwe

Official figures indicate that at least 1 million of Zimbabwe's 11 million population are infected with HIV, while the most recent survey results indicate that about 24% of apparently healthy women in the country are HIV seropositive. 60 (29.1%) of 206 pregnant women attending Edith Opperman and Budiriro clinics in Harare who were screened for infection with HIV were found to be HIV-1 seropositive. 66.6% of the HIV-1-infected women were infected with subtype C, 48.3% with subtype A, and 33.3% with subtype B. 45% of the infected were infected with subtypes A and C, 10% with A and D, 30% with B and C, and 6.6% with subtypes A, B, C, and D. 2 samples (3.3%) were nonreactive. The high prevalence rate of HIV-1 infection in this study population points to the urgent need to implement more aggressive approaches to controlling HIV/AIDS among women in Zimbabwe.     

HIV/AIDS related knowledge, attitudes, and preventive behavior of pregnant Korean women

OBJECTIVE: To assess HIV-AIDS-related knowledge, attitudes, and preventive behavior of pregnant Korean women before designing patient and public education programs. DESIGN: Pre-experimental cross-sectional survey. POPULATION, SAMPLE, SETTING, YEARS: Convenience sample of 409 women at six prenatal clinics in Seoul, Korea, in 1993. OUTCOME MEASURES: HIV-AIDS-related knowledge, attitudes, and preventive behavior. METHODS: Self-administered questionnaires. FINDINGS: The women described high levels of knowledge about HIV and AIDS risk factors but less knowledge about transmission of the virus, as well as attitudes of rejection toward unrelated people with HIV/AIDS; 16% provided condoms for their husband's use in extramarital sex, the primary risk behavior. CONCLUSIONS: Korean women are at risk for heterosexual transmission of HIV despite knowledge of risk factors. CLINICAL IMPLICATIONS: Korean education programs for women should focus on modes of heterosexual transmission, care of individuals with HIV or AIDS, self-assessment of HIV-AIDS risk, and self protection.     

Women's self-disclosure of HIV infection: Rates, reasons, and reactions.

A survey of 65 ethnically diverse women at 2 outpatient HIV clinics revealed relatively low rates of disclosure of HIV-positive serostatus to extended family members, somewhat higher rates for immediate family members, and highest rates for lovers and friends. Spanish-speaking Latinas were less likely to disclose their serostatus or to discuss HIV-related worries with others than English speaking Latinas, African Americans, and Anglo Americans. Reasons for disclosure and nondisclosure varied by target. In general, targets reacted positively to disclosure. Implications for clinicians treating women with HIV infection are discussed.

Pregnancy in HIV-infected women. Counseling and care--12 years' experiences and results

BACKGROUND: A specialized antenatal care unit was set up for counseling and care of HIV-infected pregnant women. The team consisted of gynecologists, a midwife, a social worker and pediatricians. METHODS: The women were referred from departments of infectious diseases, venereology or institutions for drug addicts, antenatal care units and abortion clinics, or applied themselves. Women identified in the pregnancy HIV screening program were informed primarily by the team. The women were counseled along with their partners and cared for during abortion or the antenatal period, delivery and post partum. Contraceptive services were offered and psychosocial support was given. RESULTS: Between April 1985 and March 1997, 95 HIV-infected women with 122 pregnancies attended. Twenty-one per cent were or had been drug users, 2% had been infected by transfused blood and 77% were classified as having been sexually infected, two thirds of whom were Africans. The mean age was 27.8 years. In 54 of 93 pregnancies (58%) in which the woman could make an informed decision, she elected abortion -- in 37 cases for HIV related reasons. Significantly more women with an uninfected steady partner, compared to women without a steady partner, chose to continue the pregnancy, as did women in a relatively stable social situation. Of the partners, 68 were HIV-negative, 36 HIV-positive and 18 not tested. No severe HIV-related complications occurred during pregnancy. Seven of 40 (18%) children with a known infection status were infected. During the course of follow-up, nine mothers, two fathers and three children have died. Seventeen children were at risk of being orphaned, and another five were placed in foster care. CONCLUSION: Although it is possible to reduce mother-to-infant transmission by zidovudine therapy, the negative consequences of HIV and childbearing are still substantial. Therefore HIV screening during pregnancy and pre-pregnancy counseling are important issues for the health care system.     

Readmissions to drug abuse treatment and HIV risk behavior

The objectives of the study were (a) to investigate the characteristics of drug abuse treatment clients who return to treatment and (b) among those with readmissions, to describe changes over time in risk behavior for human immunodeficiency virus (HIV) infection and to identify factors associated with behavior change. Data were derived from a multisite HIV surveillance program in a single community; the program used a unique identifier to link HIV test results and behavioral information from multiple contacts. During a 30-month period, 1994 clients were admitted to three satellite facilities of a single treatment agency: detoxification, long-term residential, and outpatient. Of these clients, 574 (29%) had one or more readmissions to the same or a different facility during the 24 months following the index admission. Drug injectors, those tested for HIV, and those living in the community were more likely to be readmitted to treatment. There was little overall change in HIV risk behavior between the index admission and the readmission furthest in time from the index admission. Clients whose index visit was at the residential facility were more likely to reduce their injection risk behavior than those admitted to the other facilities. Clients readmitted to either the residential or the outpatient facility were more likely to have reduced their injection risk behavior than those readmitted to detoxification. Treatment facility was not associated with sexual risk behavior change. Men were more likely than women to reduce their high-risk sexual behaviors. The results underscore the need for treatment programs to make HIV testing readily available to their clients and to make special efforts to assist female clients to reduce their HIV risk.     

HIV seroprevalence in a London same-day testing clinic

OBJECTIVES: To determine the prevalence of HIV infection among people attending a confidential, non-genitourinary medicine based testing clinic that provides HIV antibody test results on the day of consultation. METHODS: Retrospective analysis of data collected on 2635 individuals attending the Same-Day HIV Testing Clinic at the Royal Free Hospital, London between March 1992 and February 1993. RESULTS: A total of 1612 men and 1023 women were tested for HIV antibody. The primary risk for HIV infection was heterosexual (71.7%; 1889 out of 2635) and homosexual contact (24.5%; 646 out of 2635). Fifty-four individuals were given positive HIV test results (46 men, median age 34 years; eight women, median age 27 years). Overall HIV seroprevalence was 2.0% (95% confidence interval, 1.5-2.5). HIV seroprevalence was highest among homosexual men (6.5%; 41 out of 635) and injecting drug users (5.7%; four out of 70). The rates for heterosexual men and women were 0.2% (two out of 915) and 0.7% (seven out of 974), respectively. Of the 54 individuals who were HIV-antibody-positive, 44 were Centers for Disease Control and Prevention stage II/III, eight stage IV and one was tested at the time of seroconversion (stage I; data were not available for one patient). Of the total numbers attending this clinic 27% (702 out of 2635) had previously been tested and received a negative result. Of a total of 54 HIV-antibody-positive individuals, 40% (21) had previously received a negative test result. CONCLUSIONS: The data suggest that seroprevalence amongst homosexual men attending a designated HIV testing clinic in London is lower than that reported by genitourinary clinic based testing sites. The large number of repeat testers who subsequently became infected with HIV suggests that there is a population requiring specific targetting for HIV risk reduction.     

Infant birth weight among women with or at high risk for HIV infection: The impact of clinical, behavioral, psychosocial, and demographic factors.

The purpose of these analyses was to provide a prospective examination of the impact of HIV on birth weight using clinical, behavioral, psychosocial, and demographic correlates. 319 HIV-positive and 220 HIV-negative pregnant women matched for HIV risk factors (i.e., drug use and sexual risk behaviors) were interviewed during the 3rd trimester of pregnancy and 6 weeks postpartum. Medical chart reviews were also conducted for the HIV-seropositive pregnant women to verify pregnancy-related and birth outcome data. In a logistic regression analysis, controlling for parity and gestational age, women who were HIV seropositive were 2.6 times more likely to have an infant with low birth weight. Black women and those who did not live with their partners were more than 2 times as likely to have infants with low birth weight, and those who smoked were 3.2 times more likely to have infants with low birth weight. Knowing that women with HIV, those who are Black, and those not living with a partner are at highest risk for adverse birth outcomes can help those in prenatal clinics and HIV specialty clinics to target resources and develop prevention interventions. This is particularly important for women with HIV because birth weight is associated with risk of HIV transmission from mother to child. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
