RESUMEN
OBJECTIVES: To determine the effect of daily acyclovir on genital shedding of HIV-1 and herpes simplex virus type 2 (HSV-2) in a randomised placebo-controlled trial among rural Zimbabwean sex workers. METHODS: 214 women were recruited and tested for HIV-1 and HSV-2 antibodies, HIV plasma viral load, CD4 lymphocyte count and genital swabs for qualitative detection of HIV-1 and HSV-2 genital shedding. Women were randomly assigned to acyclovir 400 mg twice a day for 12 weeks or matching placebo and were followed weekly to detect HIV-1 or HSV-2 genital shedding. Shedding analyses were only undertaken on 125 women co-infected with HSV-2 and HIV-1. Data were analysed using logistic regression, with random effects modelling used to account for repeated measurements on the same women. RESULTS: All women were randomly assigned to acyclovir or placebo; 125 of whom were co-infected with HIV-1 and HSV-2. 69 women were randomly assigned to acyclovir and 56 to placebo. Although twice daily acyclovir reduced rates of HSV-2 genital shedding, (adjusted odds ratio (AOR) 0.24; 95% CI 0.12 to 0.48; less than p<0.001), it had no effect on the proportion of visits at which HIV-1 shedding was detected (AOR 1.08; 95% CI 0.48 to 2.42; p = 0.9). Adherence varied between participants but even when adherence was high (as determined by pill count and extent of HSV-2 suppression) HIV-1 shedding was not reduced. CONCLUSION: Among these HIV-1 and HSV-2-seropositive women, suppressive acyclovir therapy had no effect on the rate of HIV genital shedding despite a reduction in genital HSV-2. Treatment adherence and its measurement clearly affect the interpretation of these results.

Much attention has been placed on the need to develop and evaluate complex interventions targeting public health issues, such as reproductive health. However, and as has been the case in the recent past, even well-designed trials will be flawed unless meticulous attention is paid to ensuring the most appropriate intervention is designed and developed. This requires a well-resourced and carefully planned feasibility study, incorporating both formative and process evaluation, with particular attention being paid to the context of the proposed intervention. In this paper, we describe the way in which a feasibility study helped redesign and shape a complex intervention targeting adolescent sexual health in rural Zimbabwe. By using a mixture of in-depth interviews, focus groups and participant observation with pupils, parents, teachers and education officers, we were able to show that the intervention as originally conceived was unlikely to be deliverable. Process evaluation findings from the feasibility study led to substantial changes to both the content and delivery of the proposed intervention, which is now subject to testing for effectiveness in a large community randomized trial.

In developing countries, what advice to give HIV-positive mothers on infant feeding options remains a vexing public health issue. This paper reviews data on infant feeding practices in sub-Saharan Africa, the cultural context of breastfeeding, and the still meager literature of decision-making by HIV-positive mothers, following impartial counseling. Although prolonged breastfeeding is common, weaning foods typically are introduced early. A minority of women practice the recommended exclusive breastfeeding for 4-6 months. Breastfeeding taboos, expecially regarding colostrum, are common. The usual reason for introduction of weaning foods is to ensure that the baby has enough food. Exclusive formula feeding is perceived as stigmatizing, but acceptable with husband support. The main perceived barrier to formula is cost. Health workers may be less effective in conveying the risk of formula compared to the risk of HIV transmission in breast milk. Studies presently available regarding these issues are few and involve small samples. More studies are planned, and some are under way. By offering actual feeding choices to HIV-positive women, observing what choices they make, and monitoring the outcomes of these choices, we will be better placed to give advice.

The United States shares with Zimbabwe and South Africa a history of racial subjugation. A revision of the US racial classification to allow membership in more than one group means race may no longer be an exclusive characteristic. These issues also have been debated in southern Africa. In this commentary, the author reviews race classification in southern Africa and the use of race-specific public health data. Comparisons of illness and death rates across race groups have shown the health consequences of White privilege and Black disadvantage. But current public health data are not divided by race. The consequences of this policy are discussed.

OBJECTIVES: To compare the rate of self reported sexually transmitted diseases (STDs) among HIV infected men with men who remained HIV negative during follow up of a Harare male factory cohort. METHODS: Male factory workers were offered enrolment and behavioural data were collected at entry then every 6 months, along with HIV testing. Self report of STDs was used to calculate incidence per 100 person years. Cox proportional hazards models examined independent risk factors for STDs, with hazard ratios (HRs). RESULTS: At entry 20% of men were HIV infected and 11% reported STDs in the previous year. A total of 2777 (82%) of 3383 men enrolled were followed at least once. Compared with men who remained HIV negative, seroconverters had the highest incidence of STDs (16.8 per 100 person years; IRR = 3.3, 95% CI = 2.5-4.3); men enrolled HIV positive also reported higher STD incidence (14.5 per 100 person years, IRR = 2.8; 95% CI 2.3-5.5). Among HIV positive men, the only independent risk factor for report of urethral discharge was history of multiple partners (HR = 10, 95% CI 1.4-73.2). CONCLUSION: HIV positive men reported threefold higher incidence of STDs than HIV negative men, many related to high risk sexual behaviour.

The data of the population-based cancer registry in Harare, Zimbabwe, for 1993-1995 are presented and compared with those from 1990-1992. The most significant change in rates is the striking increase in the incidence of Kaposi's sarcoma (KS) in both men and women, compatible with the evolution of the AIDS epidemic in sub-Saharan Africa. The incidence of KS doubled in both sexes and now accounts for 31.1% of registered cancers. It has overtaken breast cancer to become the second most common tumour in African women, after cervical cancer, and is now one of the leading childhood tumours, accounting for 10. 3% of cancers recorded in children (ages 0-14). With the exception of KS, the incidence and pattern of occurrence of the other malignant neoplasms changed little during the observed 6 years.

Stored sera from a cohort of 2397 male factory workers in Harare, Zimbabwe, were screened for herpes simplex virus type 2 (HSV-2)-specific antibodies, to estimate the prevalence and incidence of genital herpes infection and to assess the relation between HSV-2 and human immunodeficiency virus (HIV) acquisition. The prevalence of HSV-2 at enrollment was 39.8%. Correlates of HSV-2 seropositivity were HIV seropositivity, marital status, history of sexually transmitted disease (STD), older age, and higher income. The incidence of HSV-2 seroconversion during follow-up was 6.2/100 person-years. Correlates of HSV-2 seroconversion were enrollment while HIV-positive or seroconversion during follow-up, reported genital ulcer, history of STD, and number of sex partners. No evidence was found that HSV-2 infection was more likely to precede HIV or vice versa. HSV-2 and HIV seropositivity are strong markers for high-risk sexual behavior. Improved interventions targeted to populations in which the incidence of either viral infection is high are needed.

INTRODUCTION: In 1980, age-adjusted mortality rates in Central Harlem were the highest among New York City's 30 health districts. This population-based study was designed to describe the self-reported frequency of selected health conditions, behavioral risk factors, preventive health practices, and drug use in the Harlem community. METHODS: From 1992 to 1994, in-person interviews were conducted among 695 adults aged 18 to 65 years who were randomly selected from dwelling-unit enumeration lists for the Central Harlem health district. Descriptive statistics were computed for men and women separately, and compared to other population-based surveys. RESULTS: Self-reported medical insurance coverage in Harlem was unexpectedly high (74% of men, 86% of women) as was lifetime use of preventive health practices, e.g., blood cholesterol screening (58% of men, 70% of women). However, lifetime rates of substance use, e.g. crack cocaine (14%) and self-reported history of traumatic events, e.g., witnessing someone seriously injured or violently killed (49% of men, 21% of women) were also high in Harlem, especially in comparison to other populations. CONCLUSIONS: This study has identified important patterns of similarities and differences in risk behaviors between Harlem and other populations. Potential solutions to the health problems of Harlem may lie in the creation of strategies that operate at the community, municipal, and regional level, as well as at the level of individual behavior and risk-taking.

OBJECTIVES: This study examined the prevalence, social correlates, and clustering of cardiovascular disease risk factors in a predominantly Black, poor, urban community. METHODS: Associations of risk factor prevalences with sociodemographic variables were examined in a population-based sample of 695 men and women aged 18 to 65 years living in Central Harlem. RESULTS: One third of the men and women were hypertensive, 48% of the men and 41% of the women were smokers, 25% of the men and 49% of the women were overweight, and 23% of the men and 35% of the women reported no leisure-time physical activity over the past month. More than 80% of the men and women had at least 1 of these risk factors, and 9% of the men and 19% of the women had 3 or more risk factors. Income and education were inversely related to hypertension, smoking, and physical inactivity. Having 3 or more risk factors was associated with low income and low education (extreme odds ratio [OR] = 10.2, 95% confidence interval [CI] = 3.0, 34.5 for education; OR = 3.7, CI = 1.6, 8.9 for income) and with a history of unstable work or of homelessness. CONCLUSIONS: Disadvantaged, urban communities are at high risk for cardiovascular disease. These results highlight the importance of socioenvironmental factors in shaping cardiovascular risk.

BACKGROUND: Zimbabwe is severely affected by the AIDS epidemic, and many cancers in African populations are related to infectious agents. OBJECTIVE: To study the current pattern, and short-term changes in incidence, of cancers related to infectious agents (and especially to HIV), with respect to the evolving epidemic of AIDS. METHODS: Analysis of data on the African population of Harare, Zimbabwe, from the Zimbabwe Cancer Registry, for the period 1990-1995. Comparison with data on prevalence of HIV seropositivity, and notifications of AIDS. RESULTS: Comparing results from 1993-1995 with those for 1990-1992 shows a continuing increase in the incidence of Kaposi's sarcoma with a doubling of the rates in both men and women. A dramatic increase in the incidence of squamous cell tumours of the conjunctiva was also observed, as well as a significant increase in the incidence of non-Hodgkin's lymphoma in women. There was no apparent increase in risk for Hodgkin's disease, myeloma, liver cancer, or cancer of the cervix. CONCLUSIONS: The AIDS epidemic has had a dramatic effect on the profile of cancer. The changes in incidence involve several cancers previously linked to AIDS in North America and Europe.

PIP: This study explores the perception of young people in Zimbabwe about their sexual behavior and risks of HIV infection. The study was undertaken in five secondary schools in a sample selected to represent a variety of communities and urban settings in the greater Harare area. A total of 56 discussion groups were held with youth of the same sex. The topics of the discussion groups include: 1) source of sex education; 2) values and beliefs about puberty and sexual activity; 3) factors in sexual decision making; 4) relationship between boyfriends and girlfriends; 5) knowledge of AIDS and other sexually transmitted diseases; and 6) communications skills and peer pressure. This study indicates that adolescents are sexually active and would benefit from a forum in which they would safely ask questions about sex, express their feelings, and learn appropriate communication skills. In order to provide this forum, an intervention was designed and tested at 36 schools. The experience of the intervention has been that teachers, if properly trained, can help adolescents acquire skills necessary for making responsible decisions about their sexual behavior.^ieng

OBJECTIVES: To assess the impact of HIV counselling and testing on HIV seroconversion and incidence of reported sexually transmitted diseases (STDs) among male factory workers in Harare, Zimbabwe. DESIGN: Prospective, observational study among men recruited to participate in a future workplace based AIDS prevention intervention. METHODS: Participants provided STD histories and blood for HIV antibody testing at enrolment and six month intervals during visits to factories. Participants received HIV test results, post test counselling, and free STD services at the project clinic. RESULTS: Between March 1993 and June 1995, 2,414 men were enrolled with 85% follow up. Overall HIV sero-incidence was 2.60 per 100 person-years; the incidence of reported STDs was 10.19 per 100 person-years. Men who obtained their HIV test results had significantly higher HIV sero-incidence and incidence of reported STDs compared to men who did not obtain their results (IRRs: 1.87, 3.47, respectively). Among men who obtained their HIV test results, a non-significant 40% decrease in HIV sero-incidence was observed after obtaining test results compared to before obtaining results (p = 0.18). The incidence of reported STDs, however, increased by 30% after obtaining HIV test results (p = 0.10). CONCLUSIONS: Decreased HIV sero-incidence in the face of increased reported STD incidence suggests that timely treatment of STDs may decrease the risk of acquiring HIV even in the absence of behaviour change. In populations with high rates of HIV and STDs, the greatest benefit of HIV counselling and testing may be achieved by simultaneously offering STD screening and treatment services.

The New York City neighborhood of Harlem has mortality rates that are among the highest in the United States. In absolute numbers, cardiovascular disease and cancer account for the overwhelming majority of deaths, especially among men, and these deaths occur at relatively young ages. The aim of this research was to examine self-reported smoking habits according to measures of socioeconomic status among Harlem men and women, in order to estimate the contribution of tobacco consumption to Harlem's remarkably high excess mortality. During 1992-1994, in-person interviews were conducted among 695 Harlem adults aged 18-65 years who were randomly selected from dwelling unit enumeration lists. The self-reported prevalence of current smoking was strikingly high among both men (48%) and women (41%), even among highly educated men (38%). The 21% of respondents without working telephones reported an even higher prevalence of current smoking (61%), indicating that national and state-based estimates which rely on telephone surveys may seriously underestimate the prevalence of smoking in poor urban communities. Among persons aged 35-64 years, the smoking attributable fractions for selected causes of death were larger in Harlem than in either New York City as a whole or the entire United States for both men and women. Tobacco consumption is likely to be one of several important mediators of the high numbers of premature deaths in Harlem.

OBJECTIVE: Zimbabwe, like other countries in sub-Saharan Africa, is experiencing a rapidly growing HIV/AIDS epidemic. It is crucial to determine risk events and socio-demographic characteristics associated with incident infections in order to tailor prevention messages accordingly. A cohort was established among factory workers with the objectives of estimating HIV incidence, seroprevalence, correlates of infection and subsequently evaluating the impact of prevention interventions. SETTING: 40 factories in Harare, Zimbabwe. DESIGN AND METHODS: HIV seroindicence [total new infections over person time (years) follow up] was estimated in a longitudinal cohort of male factory workers before and during a randomised peer education intervention. Correlates of seroconversion were identified using Cox regression analysis. RESULTS: Of 2,992 subjects enrolled there were 129 seroconversions during 1993 to 1996 follow up, yielding a 2.96 per 100 person year (PY) seroconversion incidence (95% CI = 2.47 to 3.52). Reporting a genital ulcer during follow up (Hazard ratio [HR] = 4.9, p = 0.001) having multiple sexual partners (HR = 1.9, p = 0.04), having a urethral discharge (HR = 2.1, p = 0.001), being single (HR = 2.3, p = 0.001), widowed or married but not residing with wife were independent factors significantly associated with risk of HIV seroconversion. CONCLUSIONS: Incidence of HIV identified in this economically productive sector is unacceptably high, and, disturbingly, is increasing in some age groups. Although the impact of the present intervention remains to be evaluated, the high incidence of HIV infection, points to the need for a more aggressive prevention effort in the general population.

In 1991, Zimbabwe embarked on a structural adjustment programme. In the health sector, collection of fees was enforced and fees were later increased. Utilisation subsequently declined. This paper examines the perceptions of both government nurses and health care consumers regarding the impact of adjustment on overall quality of care, including nurse professionalism, the nurse-client relationship and patient satisfaction with care. These issues were explored in a series of focus group discussions held in December 1993, about three years after policy reforms. The discussions suggested many areas of shared concern (fees, drug availability, waiting times), but divergent views regarding the process of care. Nurses were concerned mainly with overwork and patient ingratitude, and failed to recognise nurse behaviour as a major source of patient dissatisfaction. Community women saw nurses as hardened and indifferent, especially in urban areas. These differences are rooted in the perceived class differences between nurses and the communities they serve, but appear to have sharpened during the period of structural adjustment.

Between March 1993 and March 1995, volunteers at 40 Harare factories were interviewed regarding sociodemographic characteristics and behavior; HIV serostatus was also determined. Among 2,691 men enrolled, HIV prevalence was 19.4%. Prevalence rose 2-fold with each year of age in young men (< 23 years). In a multivariate logistic model that included sociodemographic and behavioral variables, compared with those between 25 and 44 years, both younger men (OR = 0.51) and older men (OR = 0.49) were less likely to be HIV positive. In addition, marriage (OR = 2.01), history of sexually transmitted disease (STD) (genital ulcer, OR = 4.93, urethral discharge OR = 1.75), multiple partners (OR = 1.58), cash payment for sex (OR = 2.55) and condom use (OR = 1.35) were all independent risk factors for HIV infection. Home ownership conferred lower risk. Self-reported condom use was seen as a marker of correct personal risk assessment men who used condoms reported more risk behavior and had a higher prevalence of HIV, either because condom use was not consistent or because infection occurred prior to adoption of condoms. This study confirms established risk factors in a general population sample not selected for high risk of HIV infection. It suggests rapid acquisition of infection among young men and the importance of marriage (and separation of spouses) as correlates of HIV infection.

Reproduction is a dual commitment, but so often in much of the world, it is seen as wholly the woman's responsibility. She bears the burden not only of pregnancy and childbirth but also the threats from excessive child bearing, some responsibility for contraception, infertility investigation and often undiagnosed sexually transmitted diseases (STDs) including AIDS. Failure to target men in reproductive health interventions has weakened the impact of reproductive health care programmes. The paper proposes that sophisticated and dynamic strategies in Africa and elsewhere which target women's reproductive health and research (such as control of STDs including AIDS, family planning, infertility investigation) require complementary linkage to the study and education of men. Men's perceptions, as well as determinants of sexual behavioural change and the socioeconomic context in which STDs, including AIDS, become rife, should be reviewed. There is a need to study and foster change to reduce or prevent poor reproductive health outcomes; to identify behaviours which could be adversely affecting women's reproductive health. Issues of gender, identity and tolerance as expressed through sexuality and procreation need to be amplified in the context of present risks in reproductive health. Researchers and providers often ignore the social significance of men. This paper reviews the impact of male dominance, as manifested through reproductive health and sexual decisions, against the background of present reproductive health problems. A research agenda should define factors at both macro and micro levels that interact to adversely impinge on reproductive health outcomes. This should be followed up by well-developed causal models of the determinants of positive reproductive health-promoting behaviours. Behaviour specific influences in sexual partnership include the degree of interpersonal support towards prevention, for example, of STDs, unwanted pregnancy or maternal deaths. Perceived efficacy and situational variables influencing male compliance in, say, condom use, form part of the wider study that addresses men. Thus preventive reproductive health initiatives and information should move from the female alone to both sexes. Women need men as partners in reproductive health who understand the risks they might be exposed to and strategies for their prevention.
PIP: In Sub-Saharan Africa, reproductive health care research and interventions as well as AIDS prevention and STD (sexually transmitted disease) control programs all place a disproportionate emphasis on women and ignore the equally important role of men. STD risk and incidence increased in the region as labor migration of husbands became necessary and the number of sexual partners for both men and women increased. In many cases, the sex behavior of married men is the main risk factor for their wives. Research into STDs and HIV has provided what is known about male sexual behavior, and AIDS has highlighted the importance of behavior in disease transmission and contraception. While HIV risk awareness is increasing, few men report condom use or appropriate changes in their behavior to minimize their risk. The female bias in family planning (FP) programs ignores the fact that in this setting men often control the contraceptive usage of their wives and adolescent children. Inclusion of men in counseling programs has led to an increase in contraceptive usage among their wives, and some data suggest that men are susceptible to change initial biases against FP. FP programs that offer infertility services are also more likely to be accepted, and whereas the women are usually blamed by their husbands for infertility, the husbands in infertile couples should be examined first. Research into sexual relationships, sex behavior, condom acceptance, and cultural constructs surrounding STD and HIV transmission is necessary and should be accomplished using a wide range of data collection methods.
