Abstract
Background Human immunodeficiency virus (HIV) remains the leading cause of years of life lost among adolescent boys in eastern and southern Africa. Medical male circumcision (MMC) is a cost-effective one-time intervention that can reduce the risk of heterosexual HIV acquisition in men by approximately 60%. Despite its importance in HIV prevention, the uptake of MMC remains suboptimal among adolescent boys. This study aimed to identify factors associated with low MMC uptake among adolescent boys in Tanzania. Methods This study was a secondary analysis of the 2016-17 Tanzania HIV Impact Survey. Descriptive statistics were used to summarize the participants' characteristics. Unadjusted and adjusted multinomial logistic regression models were fitted to identify factors associated with low MMC uptake among adolescent boys. Results A total of 2605 older adolescents (15-19 years) and 1296 young adolescents (10-14 years) were analyzed. The MMC uptake rates among older and young adolescents were 56.5% and 45.1%, respectively. Lower MMC uptake was found among respondents in rural areas (adjusted relative risk ratio [aRRR] = 0.40, 95% CI: 0.28-0.57), in the traditionally non-circumcising zone (aRRR = 0.30, 95% CI: 0.23-0.41), participants with no formal education (aRRR = 0.32, 95% CI: 0.23-0.41), and those living in lower wealth quintile households (aRRR = 0.20, 95% CI: 0.11-0.36). Respondents who were not covered by health insurance (aRRR = 0.67, 95% CI: 0.48-0.94) and those who had no comprehensive HIV knowledge (aRRR = 0.55, 95% CI: 0.44-0.70) were also found to have lower uptake of MMC. Conclusion To achieve and maintain high MMC coverage, MMC interventions for HIV prevention should focus on uncircumcised adolescent boys who are rural residents, of lower socioeconomic status, and residing in traditionally non-circumcising communities. Furthermore, dissemination of HIV knowledge and increasing health insurance coverage may encourage more adolescent boys to undergo MMC.

Abstract
Male circumcision (MC) for sexually active, HIV-negative men reduces HIV transmission and averts HIV infections. Excluding HIV-positive men from MC decreases access to additional health and hygiene benefits. In settings where HIV-testing is, or is perceived to be, required for MC, testing may reduce MC uptake. Reducing promotion of HIV testing within MC settings and promoting device-based MC may speed MC scale-up. To assess safety and efficacy of PrePex MC device among HIV-positive men, we conducted a one-arm, open-label, prospective study in otherwise healthy HIV-positive men in Zimbabwe.

Abstract
This systematic review assessed the safety and efficacy of the disposable circumcision suture device (DCSD) and conventional circumcision (CC) in the treatment of redundant prepuce and phimosis. Two independent reviewers conducted a literature search for randomized controlled trials (RCTs) using the DCSD and CC for the treatment of redundant prepuce or phimosis in China and abroad. Nine RCTs (1898 cases) were included. Compared with the CC group, the DCSD group had a shorter operative time (standardized mean difference [SMD] = -21.44; 95% confidence intervals [95% CIs] [-25.08, -17.79]; P < 0.00001), shorter wound healing time (SMD = -3.66; 95% CI [-5.46, -1.85]; P < 0.0001), less intraoperative blood loss (SMD = -9.64; 95% CI [-11.37, -7.90]; P < 0.00001), better cosmetic penile appearance (odds ratio [OR] =8.77; 95% CI [5.90, 13.02]; P < 0.00001), lower intraoperative pain score, lower 24-h postoperative pain score, lower incidence of infection, less incision edema, and fewer adverse events. There were no differences between the CC and DCSD groups in the incidences of dehiscence, or hematoma. The results of this meta-analysis indicate that the DCSD appears to be safer and more effective than CC. However, additional high-quality RCTs with larger study populations are needed.

Abstract
Background Safe male child circumcision has been recently adopted as a potential strategy to prevent HIV/AIDS transmission in later life in Botswana. Methods Data used was derived from a cross-sectional survey, the Botswana AIDS Impact Survey (BAIS) IV, conducted in 2013. A total sample of 7984 respondents in ages 15–64 years who had successfully completed the individual questionnaire during the survey were selected and included for analysis. Both descriptive and multivariable analyses were used to explore factors associated with acceptability of child circumcision. Data was analysed using SPSS version 22 program. Results Results indicate that about 84 % of participants said they would circumcise their male children aged 18 years and below, while 93 % were aware of the safe male circumcision program. Bivariate analyses results show that acceptability of child circumcision was significantly associated with sex, age, education, religion, residence, HIV status of the parent, fathers circumcision status, father's intention to circumcise and parent's knowledge about the safe male circumcision program. Multivariable analyses results indicate positive association between respondent's HIV positive status (OR, 3.5), Men's circumcision status (OR, 3.7), men's intention to circumcise (OR, 9.3) and acceptability of child circumcision. Conclusion Results of this study indicate some relatively high acceptability levels for child circumcision. Some individual behavioural factors influencing acceptability of child circumcision were also identified. This study provides a proper understanding of factors associated with acceptability of child circumcision which will ultimately enhance the successful roll-out of the school going children circumcision program in Botswana.

The when and how of male circumcision and the risk of HIV: a retrospective cross-sectional analysis of two HIV surveys from Guinea-Bissau. Pan Afr Med J 2016; 23:21.

Abstract
Introduction Male circumcision (MC) reduces the risk of HIV, and this risk reduction may be modified by socio-cultural factors such as the timing and method (medical and traditional) of circumcision. Understanding regional variations in circumcision practices and their relationship to HIV is crucial and can increase insight into the HIV epidemic in Africa. Methods We used data from two retrospective HIV surveys conducted in Guinea-Bissau from 1993 to 1996 (1996 cohort) and from 2004 to 2007 (2006 cohort). Multivariate logistical models were used to investigate the relationships between HIV risk and circumcision status, timing, method of circumcision, and socio-demographic factors. Results MC was protective against HIV infection in both cohorts, with adjusted odds ratios (AORs) of 0.28 (95% CI 0.12-0.66) and 0.30 (95% CI 0.09-0.93), respectively. We observed that post-pubertal (≥13 years) circumcision provided the highest level of HIV risk reduction in both cohorts compared to non-circumcised. However, the difference between pre-pubertal (≤12 years) and post-pubertal (≥13 years) circumcision was not significant in the multivariate analysis. Seventy-six percent (678/888) of circumcised males in the 2006 cohort were circumcised traditionally, and 7.7% of those males were HIV-infected compared to 1.9% of males circumcised medically, with AOR of 2.7 (95% CI 0.91-8.12). Conclusion MC is highly prevalent in Guinea-Bissau, but ethnic variations in method and timing may affect its protection against HIV. Our findings suggest that sexual risk behaviour and traditional circumcision may increases HIV risk. The relationship between circumcision age, sexual behaviour and HIV status remains unclear and warrants further research.

Abstract
INTRODUCTION Male circumcision (MC) reduces the risk of HIV infection. However, the risk reduction effect of MC can be modified by type of circumcision (medical, traditional and religious) and sexual risk behaviours post-circumcision. Understanding the risk behaviours associated with HIV infection among circumcised men (regardless of form of circumcision) is critical to the design of comprehensive risk reduction interventions. This study assessed risk factors for HIV infection among men circumcised through various circumcision approaches. METHODS This was a case-control study which enrolled 155 cases (HIV-infected) and 155 controls (HIV-uninfected), all of whom were men aged 18-35 years presenting at the AIDS Information Center for HIV testing and care. The outcome variable was HIV sero-status. Using SPSS version 17, multivariable logistic regression was performed to identify factors independently associated with HIV infection. RESULTS Overall, 83.9% among cases and 56.8% among controls were traditionally circumcised; 7.7% of cases and 21.3% of controls were religiously circumcised while 8.4% of cases and 21.9% of controls were medically circumcised. A higher proportion of cases than controls reported resuming sexual intercourse before complete wound healing (36.9% vs. 14.1%; p<0.01). Risk factors for HIV infection prior to circumcision were:being in a polygamous marriage (AOR: 6.6, CI: 2.3-18.8) and belonging to the Bagisu ethnic group (AOR: 6.1, CI: 2.6-14.0). After circumcision, HIV infection was associated with: being circumcised at >18 years (AOR: 5.0, CI: 2.4-10.2); resuming sexual intercourse before wound healing (AOR: 3.4, CI: 1.6-7.3); inconsistent use of condoms (AOR: 2.7, CI: 1.5-5.1); and having sexual intercourse under the influence of peers (AOR: 2.9, CI: 1.5-5.5). Men who had religious circumcision were less likely to have HIV infection (AOR: 0.4, 95% CI: 0.2-0.9) than the traditionally circumcised but there was no statistically significant difference between those who were traditionally circumcised and those who were medically circumcised (AOR: 0.40, 95% CI: 0.1-1.1). CONCLUSIONS Being circumcised at adulthood, resumption of sexual intercourse before wound healing, inconsistent condom use and having sex under the influence of peers were significant risk factors for HIV infection. Risk reduction messages should address these risk factors, especially among traditionally circumcised men.

Abstract
BACKGROUND Male medical circumcision (MMC) has been shown to reduce the risk of HIV transmission in circumcised men by up to 60%. Following recommendations from the World Health Organization, South Africa adopted MMC as a preventative strategy against HIV in 2010 and set up circumcision camps across the country. Concerns have been raised about condom avoidance following MMC because of a mistaken belief about the benefits of MMC.Aim and setting: The aim of this study was to describe the profile and knowledge about HIV and circumcision amongst men presenting for MMC in an urban area in KwaZulu-Natal. METHODS This was a cross-sectional descriptive study of 394 clients over the age of 18 years who presented to two MMC sites in Durban between November 2012 and March 2013. A validated questionnaire was used to collect data. RESULTS The mean age of clients presenting for MMC was 28 years. Most clients were black, single, unemployed and sexually active. The majority presented for MMC because they believed that MMC would reduce their risk of acquiring HIV infection. Knowledge about HIV transmission was very good and 86.3% of clients were aware that risky sexual behaviour such as condom avoidance could reverse the benefits of MMC. CONCLUSION The knowledge of HIV and benefits of MMC was very good amongst those presenting for MMC. However as MMC is primarily a preventative strategy, innovative methods to promote MMC prior to first sexual encounter need to be explored. Further research is needed to determine whether the benefits of MMC on the reduction of HIV transmission are sustained in routine practice.

Abstract
Understanding HIV transmission dynamics is critical to estimating the potential population-wide impact of HIV prevention and treatment interventions. We developed an individual-based simulation model of the heterosexual HIV epidemic in South Africa and linked it to the previously published Cost-Effectiveness of Preventing AIDS Complications (CEPAC) International Model, which simulates the natural history and treatment of HIV. In this new model, the CEPAC Dynamic Model (CDM), the probability of HIV transmission per sexual encounter between short-term, long-term and commercial sex worker partners depends upon the HIV RNA and disease stage of the infected partner, condom use, and the circumcision status of the uninfected male partner. We included behavioral, demographic and biological values in the CDM and calibrated to HIV prevalence in South Africa pre-antiretroviral therapy. Using a multi-step fitting procedure based on Bayesian melding methodology, we performed 264,225 simulations of the HIV epidemic in South Africa and identified 3,750 parameter sets that created an epidemic and had behavioral characteristics representative of a South African population pre-ART. Of these parameter sets, 564 contributed 90% of the likelihood weight to the fit, and closely reproduced the UNAIDS HIV prevalence curve in South Africa from 1990–2002. The calibration was sensitive to changes in the rate of formation of short-duration partnerships and to the partnership acquisition rate among high-risk individuals, both of which impacted concurrency. Runs that closely fit to historical HIV prevalence reflect diverse ranges for individual parameter values and predict a wide range of possible steady-state prevalence in the absence of interventions, illustrating the value of the calibration procedure and utility of the model for evaluating interventions. This model, which includes detailed behavioral patterns and HIV natural history, closely fits HIV prevalence estimates.

We assessed medical male circumcision (MMC) coverage and knowledge and attitudes toward MMC adoption in men in Rakai, Uganda after 4 years of scale-up. MMC prevalence only reached 28 %, with an annual increase of 4 %. Prevalence was lower in men not using condoms or having never received HIV testing and counseling. Over 95 % of uncircumcised men knew the health benefits of and places offering MMC, but only 27 % were willing to adopt MMC. Main reasons for non-acceptance were fear of pain or injury. The data suggest MMC uptake in Rakai has been suboptimal and demand generation is key for scale-up.

Abstract
Central Asia is experiencing one of the fastest growing HIV epidemics in the world, with some areas' infection rates doubling yearly since 2000. This study examines the impact of multilevel stigma (individual, family, and community) on uptake of HIV testing and receipt of HIV testing results among women in Central Asia. The sample consists of 38,884 ever-married, Central Asian women between the ages of 15 and 49. Using multilevel modeling (MLM), HIV stigma variables at the individual, family, and community levels were used to assess the significance of differences in HIV testing and receipt of HIV test results among participants while adjusting for possible confounding factors, such as age, wealth, and education. MLM results indicate that HIV stigma is significantly associated with decreased HIV testing uptake at the individual, family, and community levels and with a decrease in receipt at the community level. A one standard deviation increase in individual, family, and community level composite stigma score was associated with a respective 49 %, 59 %, and 94 % (p < 0.001) decrease in the odds of having been tested for HIV. A one standard deviation increase in community composite stigma score was associated with a 99 % (p < 0.001) decrease in the odds of test receipt. HIV stigma operates on the individual, family, and community levels to hinder HIV testing uptake and at the community level to hinder receipt. These findings have important interventions implications to improve uptake of HIV testing and receipt of HIV test results.

Abstract
Early achievements in biomedical approaches for HIV prevention included physical barriers (condoms), clean injection equipment (both for medical use and for injection drug users), blood and blood product safety, and prevention of mother-to-child transmission. In recent years, antiretroviral drugs to reduce the risk of transmission (when the infected person takes the medicines; treatment as prevention) or reduce the risk of acquisition (when the seronegative person takes them; preexposure prophylaxis) have proven to be efficacious. Circumcision of men has also been a major tool relevant for higher prevalence regions such as sub-Saharan Africa. Well-established prevention strategies in the control of sexually transmitted diseases and tuberculosis are highly relevant for HIV (ie, screening, linkage to care, early treatment, and contact tracing). Unfortunately, only slow progress is being made in some available HIV-prevention strategies such as family planning for HIV-infected women who do not want more children and prevention of mother-to-child HIV transmission. Current studies seek to integrate strategies into approaches that combine biomedical, behavioral, and structural methods to achieve prevention synergies. This review identifies the major biomedical approaches demonstrated to be efficacious that are now available. We also highlight the need for behavioral risk reduction and adherence as essential components of any biomedical approach.

Abstract
Poverty may influence HIV risk by increasing vulnerability to economic shocks and thereby preventing key health investments. We explored this possibility by examining the relationship between household shocks and the timing of traditional male circumcision, a practice associated with considerable expense and whose HIV-prevention benefits are larger when done earlier, even within young adulthood. Using unique data on a sample of Xhosa men, a group that almost universally practices traditional circumcision, we found that respondents in the poorest households delayed circumcision by 2 years if a household member experienced loss of income or death and/or illness. The impact of these shocks declined with increasing household income. Our findings suggest that interventions that work to mitigate the impact of shocks among the poor may be useful in HIV prevention efforts. More generally, they illustrate that the relationship between HIV and wealth may be more nuanced than assumed in previous work.

Abstract
This study was designed to gain baseline information on the capability of the hospitals of Thailand to provide newborn male circumcision (NC) and on the opinions of health-care personnel towards NC. Two questionnaires were sent to every hospital in Thailand that might have obstetrical services. One questionnaire requested information about the degree to which NC was provided by the hospital. The second questionnaire targeted health-care providers' opinions about NC. The response rate was 55.1% (747/1355). Of the 562 hospitals that had deliveries in 2010, 8.2% (46) provided at least one NC. Thirty-eight percent (35/92) of private hospitals and 2.3% (11/470) of government hospitals provided the service. The primary reason for performing NC was parental request (82.6%). Some providers (31.3%) said that NC was easy to perform and 39.1% thought NC was safe. Most respondents (91.8%) stated that physicians should perform the procedure instead of nurses, and choices about undergoing NC should be left to parents (55.0%). NC was rarely performed in government hospitals, and its staffs seemed to not recognize the health benefits of NC. A massive education program for health-care providers would be necessary before implementing a national program for NC. More information on the opinions of health authorities, health-care personnel and parents as well as cost-effectiveness studies are needed before a proper policy can be implemented.

Abstract
Male circumcision consists of the surgical removal of some, or all, of the foreskin (or prepuce) from the penis. It is one of the most common procedures in the world. In the United States, the procedure is commonly performed during the newborn period. In 2007, the American Academy of Pediatrics (AAP) convened a multidisciplinary workgroup of AAP members and other stakeholders to evaluate the evidence regarding male circumcision and update the AAP's 1999 recommendations in this area. The Task Force included AAP representatives from specialty areas as well as members of the AAP Board of Directors and liaisons representing the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, and the Centers for Disease Control and Prevention. The Task Force members identified selected topics relevant to male circumcision and conducted a critical review of peer-reviewed literature by using the American Heart Association's template for evidence evaluation. Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks; furthermore, the benefits of newborn male circumcision justify access to this procedure for families who choose it. Specific benefits from male circumcision were identified for the prevention of urinary tract infections, acquisition of HIV, transmission of some sexually transmitted infections, and penile cancer. Male circumcision does not appear to adversely affect penile sexual function/sensitivity or sexual satisfaction. It is imperative that those providing circumcision are adequately trained and that both sterile techniques and effective pain management are used. Significant acute complications are rare. In general, untrained providers who perform circumcisions have more complications than well-trained providers who perform the procedure, regardless of whether the former are physicians, nurses, or traditional religious providers. Parents are entitled to factually correct, nonbiased information about circumcision and should receive this information from clinicians before conception or early in pregnancy, which is when parents typically make circumcision decisions. Parents should determine what is in the best interest of their child. Physicians who counsel families about this decision should provide assistance by explaining the potential benefits and risks and ensuring that parents understand that circumcision is an elective procedure. The Task Force strongly recommends the creation, revision, and enhancement of educational materials to assist parents of male infants with the care of circumcised and uncircumcised penises. The Task Force also strongly recommends the development of educational materials for providers to enhance practitioners' competency in discussing circumcision's benefits and risks with parents. The Task Force made the following recommendations:Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks, and the benefits of newborn male circumcision justify access to this procedure for those families who choose it. Parents are entitled to factually correct, nonbiased information about circumcision that should be provided before conception and early in pregnancy, when parents are most likely to be weighing the option of circumcision of a male child. Physicians counseling families about elective male circumcision should assist parents by explaining, in a nonbiased manner, the potential benefits and risks and by ensuring that they understand the elective nature of the procedure. Parents should weigh the health benefits and risks in light of their own religious, cultural, and personal preferences, as the medical benefits alone may not outweigh these other considerations for individual families. Parents of newborn boys should be instructed in the care of the penis, regardless of whether the newborn has been circumcised or not. Elective circumcision should be performed only if the infant's condition is stable and healthy. Male circumcision should be performed by trained and competent practitioners, by using sterile techniques and effective pain management. Analgesia is safe and effective in reducing the procedural pain associated with newborn circumcision; thus, adequate analgesia should be provided whenever newborn circumcision is performed.Nonpharmacologic techniques (eg, positioning, sucrose pacifiers) alone are insufficient to prevent procedural and postprocedural pain and are not recommended as the sole method of analgesia. They should be used only as analgesic adjuncts to improve infant comfort during circumcision. If used, topical creams may cause a higher incidence of skin irritation in low birth weight infants, compared with infants of normal weight; penile nerve block techniques should therefore be chosen for this group of newborns. Key professional organizations (AAP, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, the American Society of Anesthesiologists, the American College of Nurse Midwives, and other midlevel clinicians such as nurse practitioners) should work collaboratively to:Develop standards of trainee proficiency in the performance of anesthetic and procedure techniques, including suturing; Teach the procedure and analgesic techniques during postgraduate training programs; Develop educational materials for clinicians to enhance their own competency in discussing the benefits and risks of circumcision with parents; Offer educational materials to assist parents of male infants with the care of both circumcised and uncircumcised penises. The preventive and public health benefits associated with newborn male circumcision warrant third-party reimbursement of the procedure. The American College of Obstetricians and Gynecologists has endorsed this technical report.

The perceptions on male circumcision as a preventive measure against HIV infection and considerations in scaling up of the services: a qualitative study among police officers in Dar es Salaam, Tanzania. BMC Public Health 2012; 12:529. [PMID: 22812484 PMCID: PMC3416658 DOI: 10.1186/1471-2458-12-529] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2012] [Accepted: 07/03/2012] [Indexed: 11/13/2022] Open
Abstract
Background In recent randomized controlled trials, male circumcision has been proven to complement the available biomedical interventions in decreasing HIV transmission from infected women to uninfected men. Consequently, Tanzania is striving to scale-up safe medical male circumcision to reduce HIV transmission. However, there is a need to investigate the perceptions of male circumcision in Tanzania using specific populations. The purpose of the present study was to assess the perceptions of male circumcision in a cohort of police officers that also served as a source of volunteers for a phase I/II HIV vaccine (HIVIS-03) trial in Dar es Salaam, Tanzania. Methods In-depth interviews with 24 men and 10 women were conducted. Content analysis informed by the socio-ecological model was used to analyze the data. Results Informants perceived male circumcision as a health-promoting practice that may prevent HIV transmission and other sexually transmitted infections. They reported male circumcision promotes sexual pleasure, confidence and hygiene or sexual cleanliness. They added that it is a religious ritual and a cultural practice that enhances the recognition of manhood in the community. However, informants were concerned about the cost involved in male circumcision and cleanliness of instruments used in medical and traditional male circumcision. They also expressed confusion about the shame of undergoing circumcision at an advanced age and pain that could emanate after circumcision. The participants advocated for health policies that promote medical male circumcision at childhood, specifically along with the vaccination program. Conclusions The perceived benefit of male circumcision as a preventive strategy to HIV and other sexually transmitted infections is important. However, there is a need to ensure that male circumcision is conducted under hygienic conditions. Integrating male circumcision service in the routine childhood vaccination program may increase its coverage at early childhood. The findings from this investigation provide contextual understanding that may assist in scaling-up male circumcision in Tanzania.

Abstract
BACKGROUND The efficacy of male circumcision for HIV prevention over 2 years has been demonstrated in three randomized trials, but the longer-term effectiveness of male circumcision is unknown. METHODS We conducted a randomized trial of male circumcision in 4996 HIV-negative men aged 15-49 in Rakai, Uganda. Following trial closure, we offered male circumcision to control participants and have maintained surveillance for up to 4.79 years. HIV incidence per 100 person-years was assessed in an as-treated analysis, and the effectiveness of male circumcision was estimated using Cox regression models, adjusted for sociodemographic and time-dependent sexual behaviors. For men uncircumcised at trial closure, sexual risk behaviors at the last trial and first posttrial visits were assessed by subsequent circumcision acceptance to detect behavioral risk compensation. RESULTS By 15 December 2010, 78.4% of uncircumcised trial participants accepted male circumcision following trial closure. During posttrial surveillance, overall HIV incidence was 0.50/100 person-years in circumcised men and 1.93/100 person-years in uncircumcised men {adjusted effectiveness 73% [95% confidence interval (CI) 55-84%]}. In control arm participants, posttrial HIV incidence was 0.54/100 person-years in circumcised and 1.71/100 person-years in uncircumcised men [adjusted effectiveness 67% (95% CI 38-83%)]. There were no significant differences in sociodemographic characteristics and sexual behaviors between controls accepting male circumcision and those remaining uncircumcised. CONCLUSION High effectiveness of male circumcision for HIV prevention was maintained for almost 5 years following trial closure. There was no self-selection or evidence of behavioral risk compensation associated with posttrial male circumcision acceptance.

Voluntary medical male circumcision: a cross-sectional study comparing circumcision self-report and physical examination findings in Lesotho. PLoS One 2011; 6:e27561.

Abstract
Background Overwhelming evidence, including three clinical trials, shows that male circumcision (MC) reduces the risk of HIV infection among men. However, data from recent Lesotho Demographic and Health Surveys do not demonstrate MC to be protective against HIV. These contradictory findings could partially be due to inaccurate self-reported MC status used to estimate MC prevalence. This study describes MC characteristics among men applying for Lesotho Defence Force recruitment and seeks to assess MC self-reported accuracy through comparison with physical-examination-based data. Methods and Findings During Lesotho Defence Force applicant screening in 2009, 241 (77%) of 312 men, aged 18–25 y, consented to a self-administered demographic and MC characteristic survey and physician-performed genital examination. The extent of foreskin removal was graded on a scale of 1 (no evidence of MC) to 4 (complete MC). MC was self-reported by 27% (n = 64/239) of participants. Of the 64 men self-reporting being circumcised, physical exam showed that 23% had no evidence of circumcision, 27% had partial circumcision, and 50% had complete circumcision. Of the MCs reportedly performed by a medical provider, 3% were Grade 1 and 73% were Grade 4. Of the MCs reportedly performed by traditional circumcisers, 41% were Grade 1, while 28% were Grade 4. Among participants self-reporting being circumcised, the odds of MC status misclassification were seven times higher among those reportedly circumcised by initiation school personnel (odds ratio = 7.22; 95% CI = 2.29–22.75). Conclusions Approximately 27% of participants self-reported being circumcised. However, only 50% of these men had complete MC as determined by a physical exam. Given this low MC self-report accuracy, countries scaling up voluntary medical MC (VMMC) should obtain physical-exam-based MC data to guide service delivery and cost estimates. HIV prevention messages promoting VMMC should provide comprehensive education regarding the definition of VMMC.

Abstract
BACKGROUND Male circumcision is being promoted to reduce human immunodeficiency virus type 1 (HIV) infection rates. This review evaluates the scientific evidence suggesting that male circumcision reduces HIV infection risk in high-risk heterosexual populations. METHODS We followed the updated International Consultation on Urological Diseases evidence-based medicine recommendations to critically review the scientific evidence on male circumcision and HIV infection risk. RESULTS Level 1 evidence supports the concept that male circumcision substantially reduces the risk of HIV infection. Three major lines of evidence support this conclusion: biological data suggesting that this concept is plausible, data from observational studies supported by high-quality meta-analyses, and three randomized clinical trials supported by high-quality meta-analyses. CONCLUSIONS The evidence from these biological studies, observational studies, randomized controlled clinical trials, meta-analyses, and cost-effectiveness studies is conclusive. The challenges to implementation of male circumcision as a public health measure in high-risk populations must now be faced.

Abstract
Education has a potentially important role to play in tackling the spread of HIV, but is there evidence that this potential is realized? This analysis combines the results of previous literature reviews and updates them with the findings of recent randomized controlled trials and a discussion of possible mechanisms for the effect of schooling on vulnerability to HIV infection. There is a growing body of evidence that keeping girls in school reduces their risk of contracting HIV. The relationship between educational attainment and HIV has changed over time, with educational attainment now more likely to be associated with a lower risk of HIV infection than earlier in the epidemic. Educational attainment cannot, however, be isolated from other socioeconomic factors as the cause of HIV risk reduction. The findings of this analysis suggest that the equitable expansion of primary and secondary schooling for girls in southern Africa will help reduce their vulnerability to HIV. Evidence of ineffective HIV prevention education in schools underlines the need for careful evidence-based programme design. Despite the challenges, recent provisional evidence suggests that highly targeted programmes promoting realistic options for young adults may lead to safer sexual behaviour. Targeted education programmes have also been successful in changing students' attitudes to people living with HIV and AIDS, which is associated with testing and treatment decisions. This reduction in stigma may be crucial in encouraging the uptake of voluntary counselling and testing, a central strategy in the control of the epidemic. Expansions of carefully designed and evaluated school-based HIV prevention programmes can help to reduce stigma and have the potential to promote safe sexual behaviour.

Abstract
Whether the observed association between male circumcision and HIV infection is causal or not has not been verified. We did a meta-analysis of published data and applied Hill's criteria for causality on all available evidence to assess presence of a causal association. Analysis was by the random effects method. Summary estimates were calculated for all studies combined and for sub groups stratified by type of study population, study design, and method of ascertaining circumcision status. Thirteen studies were included. Circumcised men had a reduced risk for HIV infection (adjusted RRoverall = 0.42, 95% CI 0.33-0.53; RR(RCT) = 0.43 95% CI 0.32-0.59, RRobservational = 0.39, 95% CI 0.27-0.56). Available evidence satisfies six of Hill's criteria: strength of association, consistency, temporality, coherence, biological plausibility, and experiment. These results provide unequivocal evidence that circumcision plays a causal role in reducing the risk of HIV infection among men.

Abstract
OBJECTIVE Previous studies found educated individuals to have higher risk of human immunodeficiency virus (HIV)-1 infection in Africa. A reverse in this association was predicted. We investigated the change in this association from 1991 to 2005 in a rural population in Tanzania. STUDY DESIGN Two cross-sectional surveys were conducted in 1991(N = 1,152, response rate 76.4%) and 2005 (N = 1,528, 73.0%). Consenting individuals aged 15 to 44 years living in Oria village were interviewed and gave blood for HIV-1 testing. RESULTS Primary [adjusted odds ratio (AOR), 2.7; 95% confidence interval (CI): 1.3-20.0] and secondary/higher education (AOR, 4.5; 95% CI: 1.4-24.9) were associated with increased risk of HIV-1 infection in 1991. A reversed association was observed in 2005 where reduced odds of infection were associated with primary (AOR, 0.5; 95% CI: 0.2-0.8) and secondary/higher education (AOR, 0.4; 95% CI: 0.3-0.9). This was most pronounced among educated men. Corresponding reduction in risk behaviors were observed. Increased odds of reporting ever use of condom (AOR, 2.8; 95% CI: 1.1-7.3) and 70% reduction in reporting >or=2 sexual partners in the past year was observed among educated women. Educated men reported 60% reduction in the odds of reporting >or=2 sexual partners in the past month preceding the last survey. CONCLUSIONS A reversed association between education attainment and HIV-1 infection was observed in this population between 1991 and 2005. Education seems to have an empowering role in women. Decreased risk among educated men may have an impact on HIV-1 transmission. Improving education sector in rural areas might be instrumental in the fight against the HIV epidemic.

Abstract
Background It is commonly assumed that sexual risk factors for heterosexual HIV transmission in sub-Saharan Africa, such as multi-partner sex, paid sex and co-infections, become less important as HIV epidemics mature and prevalence increases. Methods and Findings We conducted a systematic review of 68 African epidemiological studies from 1986 to 2006 involving 17,000 HIV positive adults and 73,000 controls. We used random-effects methods and stratified results by gender, time, background HIV prevalence rates and other variables. The number of sex partners, history of paid sex, and infection with herpes simplex virus (HSV-2) or other sexually-transmitted infections (STIs) each showed significant associations with HIV infection. Among the general population, the odds ratio (OR) of HIV infection for women reporting 3+ sex partners versus 0–2 was 3.64 (95%CI [2.87–4.62]), with similar risks for men. About 9% of infected women reported ever having been paid for sex, versus 4% of control women (OR = 2.29, [1.45–3.62]). About 31% of infected men reported ever paying for sex versus 18% of uninfected men (OR = 1.75, [1.30–2.36]). HSV-2 infection carried the largest risk of HIV infection: OR = 4.62, [2.85–7.47] in women, and OR = 6.97, [4.68–10.38] in men. These risks changed little over time and stratification by lower and higher HIV background prevalence showed that risk ratios for most variables were larger in high prevalence settings. Among uninfected controls, the male-female differences in the number of sex partners and in paid sex were more extreme in the higher HIV prevalence settings than in the lower prevalence settings. Significance Multi-partner sex, paid sex, STIs and HSV-2 infection are as important to HIV transmission in advanced as in early HIV epidemics. Even in high prevalence settings, prevention among people with high rates of partner change, such as female sex workers and their male clients, is likely to reduce transmission overall.

Abstract
OBJECTIVE To conduct a critical peer-review of the 2004 Policy Statement on routine male circumcision produced by the Royal Australasian College of Physicians (RACP). METHOD Comprehensive evaluation in the context of the research field. RESULTS We find that the current Statement downplays the wide-ranging life-long benefits of circumcision in prevention of urinary tract infections (UTIs), penile and cervical cancer, genital herpes and chlamydia in women, HIV infection, phimosis, and various penile dermatoses, and at the same time overstates the complication rate. We highlight the many errors in the RACP Statement and note that it sidesteps making a conclusion based on circumcision's well-documented prophylactic health benefits by instead referring to the status of the foreskin at birth. In the era of preventative medicine we view this as irresponsible. CONCLUSION The RACP's Statement on routine male circumcision is not evidence-based and should be retracted. IMPLICATIONS In the interests of public health and individual well-being an extensive, comprehensive, evidence-based revision should be conducted so as to provide scientifically accurate, balanced information on the advantages, and also the low rate of mostly minor complications, associated with this simple procedure, which for maximum benefits and minimal risk should ideally be performed in the neonatal period.

Abstract
OBJECTIVES To estimate the impact of male circumcision on HIV incidence, the number of procedures per HIV infection averted, and costs per infection averted. METHODS A stochastic simulation model with empirically derived parameters from a cohort in Rakai, Uganda was used to estimate HIV incidence, assuming that male circumcision reduced the risks of HIV acquisition with rate ratios (RR) ranging from 0.3 to 0.6 in men, their female partners, and in both sexes combined, with circumcision coverage 0-100%. The reproductive number (R0) was also estimated. The number of HIV infections averted per circumcision was estimated from the incident cases in the absence of surgery minus the projected number of incident cases over 10 years following circumcision. The cost per procedure ($69.00) was used to estimate the cost per HIV infection averted. RESULTS Baseline HIV incidence was 1.2/100 person-years. Male circumcision could markedly reduce HIV incidence in this population, particularly if there was preventative efficacy in both sexes. Under many scenarios, with RR < or = 0.5, circumcision could reduce R0 to < 1.0 and potentially abort the epidemic. The number of surgeries per infection averted over 10 years was 19-58, and the costs per infection averted was $1269-3911, depending on the efficacy of circumcision for either or both sexes, assuming 75% service coverage. However, behavioral disinhibition could offset any benefits of circumcision. CONCLUSION Male circumcision could have substantial impact on the HIV epidemic and provide a cost-effective prevention strategy if benefits are not countered by behavioral disinhibition.

Abstract
PURPOSE Remarkable proportions of self-reported virgins and adolescents in eastern and southern Africa are infected with HIV, yet non-sexual routes of transmission have not been systematically investigated in such persons. Many observers in this region have recognized the potential for HIV transmission through unhygienic circumcision procedures. We assessed the relation between male and female circumcision (genital cutting) and prevalent HIV infection in Kenyan, Lesothoan, and Tanzanian virgins and adolescents. METHODS We analyzed data from recent cross-sectional national probability sample surveys of adolescents and adults in households, focusing on populations in which circumcision was common and usually occurred in puberty or later. RESULTS Circumcised male and female virgins were substantially more likely to be HIV infected than uncircumcised virgins (Kenyan females: 3.2% vs. 1.4%, odds ratio [OR] = 2.38; Kenyan males: 1.8% vs. 0%, OR undefined; Lesothoan males: 6.1% vs. 1.9%, OR 3.36; Tanzanian males: 2.9% vs. 1.0%, OR 2.99; weighted mean phi correlation = 0.07, 95% confidence interval, 0.03 to 0.11). Among adolescents, regardless of sexual experience, circumcision was just as strongly associated with prevalent HIV infection. However, uncircumcised adults were more likely to be HIV positive than circumcised adults. Self-reported sexual experience was independently related to HIV infection in adolescent Kenyan females, but was unrelated to HIV infection in adolescent Kenyan, Lesothoan, and Tanzanian males. CONCLUSIONS HIV transmission may occur through circumcision-related blood exposures in eastern and southern Africa.

Abstract
OBJECTIVES Previous research suggests that male circumcision may be a protective factor against the acquisition of sexually transmitted infections; however, studies examining this question have produced mixed results. The aim of this study was to examine the association between circumcision status and sexually transmitted infection risk using a longitudinal birth cohort study. METHODS Data were gathered as part of the Christchurch Health and Development Study, a 25-year longitudinal study of a birth cohort of New Zealand children. Information was obtained on: (1) the circumcision status of males in the cohort before 15 years old, (2) measures of self-reported sexually transmitted infection from ages 18 to 25 years, and (3) childhood, family, and related covariate factors. RESULTS Being uncircumcised had a statistically significant bivariate association with self-reported sexually transmitted infection. Adjustment for potentially confounding factors, including number of sexual partners and unprotected sex, as well as background and family factors related to circumcision, did not reduce the association between circumcision status and reports of sexually transmitted infection. Estimates of the population-attributable risk suggested that universal neonatal circumcision would have reduced rates of sexually transmitted infection in this cohort by 48.2%. CONCLUSIONS These findings suggest that uncircumcised males are at greater risk of acquiring sexually transmitted infection than circumcised males. Male circumcision may reduce the risk of sexually transmitted infection acquisition and transmission by up to one half, suggesting substantial benefits accruing from routine neonatal circumcision.

Abstract
OBJECTIVES Male circumcision is associated with reduced risk of HIV infection. This may be partly because of a protective effect of circumcision on other sexually transmitted infections (STI), especially those causing genital ulcers, but evidence for such protection is unclear. Our objective was to conduct a systematic review and meta-analyses of the associations between male circumcision and infection with herpes simplex virus type 2 (HSV-2), Treponema pallidum, or Haemophilus ducreyi. METHODS Electronic databases (1950-2004) were searched using keywords and text terms for herpes simplex, syphilis, chancroid, ulcerative sexually transmitted diseases, or their causative agents, in conjunction with terms to identify epidemiological studies. References of key articles were hand searched, and data were extracted using standardised forms. Random effects models were used to summarise relative risk (RR) where appropriate. RESULTS 26 articles met the inclusion criteria. Most syphilis studies reported a substantially reduced risk among circumcised men (summary RR = 0.67, 95% confidence interval (CI) 0.54 to 0.83), although there was significant between study heterogeneity (p = 0.01). The reduced risk of HSV-2 infection was of borderline statistical significance (summary RR = 0.88, 95% CI 0.77 to 1.01). Circumcised men were at lower risk of chancroid in six of seven studies (individual study RRs: 0.12 to 1.11). CONCLUSIONS This first systematic review of male circumcision and ulcerative STI strongly indicates that circumcised men are at lower risk of chancroid and syphilis. There is less association with HSV-2. Potential male circumcision interventions to reduce HIV in high risk populations may provide additional benefit by protecting against other STI.

Abstract
BACKGROUND Most studies that have found an association between uncircumcised status and infection with human immunodeficiency virus type 1 (HIV-1) have compared participants from various demographic backgrounds, among which the prevalence of other risk factors might have varied. We report findings from a study conducted among men within a single ethnic community in which circumcision was dictated by the religious denomination to which the men belonged. METHODS Of the 1217 eligible men, we included in the analysis 845 who gave blood samples for HIV-1 testing and who were confirmed as either fully circumcised (n = 398) or uncircumcised (n = 447). The seroprevalence of HIV-1 was compared between the 2 groups. RESULTS All correlates of HIV-1 prevalence that we measured were distributed similarly between circumcised and uncircumcised men. The seroprevalence of HIV-1 was 30% among the uncircumcised men and 20% among the circumcised men. Among uncircumcised men, HIV-1 seroprevalence was similar between men from circumcising denominations (31%; n = 111) and noncircumcising denominations (30%; n = 336). The crude prevalence ratio for HIV infection associated with not being circumcised was 1.5 (95% confidence interval = 1.2-2.0); and adjustment for other measured risk factors for HIV-1 infection had little impact on this result. CONCLUSION Our study provides evidence that circumcision is associated with a reduced risk of HIV-1 infection.

Abstract
UNLABELLED Untimely old, circumcision has elicited more controversy and war of words than any surgical procedure in history. Although previous claims of benefits like curing masturbation, gout, epilepsy, and even insanity were no doubt absurd, important research has shed light on real medical benefits of circumcision. In particular, the procedure has consistently shown to result in the decreased risk of debilitating and costly diseases such as HIV, cervical cancer, and infantile urinary tract infection. Because of advances in the understanding of the anatomy of the foreskin and pain conditioning in infants, prevailing attitudes have changed about anesthesia and analgesia during the procedure. This article objectively summarizes the bulk of significant medical literature over the last century to provide an accurate statement about what we know and what we do not know about neonatal circumcision, including its history, epidemiology, medical benefits, complications, contraindications, techniques, management for pain, and current controversies. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to describe the evolution of circumcision, to list the potential benefits of circumcision, to outline the various neonatal circumcision techniques, and to summarize the data on the use of analgesia for circumcision.

Abstract
BACKGROUND The association between educational attainment and risk of HIV infection varies between populations and over time. Earlier studies in sub-Saharan Africa have found that those with more education are at increased risk of HIV infection. METHODS We investigated the associations between general schooling and both HIV and herpes simplex-2 (HSV-2) infection using data from the multicentre study on factors determining the differential spread of HIV in four African cities. Cross-sectional general population studies were conducted in 1997-1998 in Cotonou (Benin), Yaoundé (Cameroon), Kisumu (Kenya), and Ndola (Zambia), including about 2000 adults in each city. RESULTS There was no association between schooling and HIV infection in men or women in Kisumu or Ndola. Women in Yaoundé and men in Cotonou, with more schooling, were less likely to be HIV positive. These associations persisted after adjusting for sociodemographic factors. Similar trends in men in Yaoundé and women in Cotonou were not statistically significant. Increased schooling was associated with significantly decreased risk of HSV-2 infection in women in Kisumu and Ndola and men in Cotonou. In all the cities those with more education tended to report less risky sexual behaviour. CONCLUSIONS There was no evidence of an increased risk of HIV infection associated with education as seen in earlier studies. In each city there was some evidence of lower HIV or HSV-2 infection rates and less risky sexual behaviour associated with increased education levels. The most educated may be responding more readily to health education programmes. The challenge is to extend this to the rest of the population.

Abstract
The study aims to investigate the potential for an intervention based on male circumcision in a South African town with a high level of HIV infection. It draws on two cross-sectional studies conducted in August 2000 among a sample of 606 male adults aged 13-59 years, and in August 1999 among a sample of 723 male youth aged 14-24 years. A qualitative study was further conducted on perceptions and attitudes towards male circumcision using focus group discussions and in-depth interview. Among men aged 25-59 years, 36% reported being circumcised The median reported age at circumcision was 20. A total of 42% of 14-24-year-old circumcised men reported having been circumcised in a medical setting. Circumcised and uncircumcised men did not differ in their sexual behaviour or in sociodemographic characteristics, apart from their age and ethnic group. Among 467 uncircumcised adult men, 59% said that they would be circumcised if circumcision reduced the chances of getting HIV and STDs. Focus group discussions showed that circumcision is still important to many people, and is seen as an essential part of the transition into adulthood Reluctance to be circumcised was mainly related to the possibility of adverse outcomes of circumcision performed in non-medical settings, although initiation schools remain attractive for education and transmission of cultural values. Some misconceptions remain, however, especially about the preventative nature of circumcision for STD transmission. The cultural importance of male circumcision has weakened over the last century and when it is done it is often by a medical practitioner. An intervention that would include male circumcision seems feasible in communities such as the one where this study was conducted but needs to be carefully planned in order to ensure that participants understand that circumcision probably reduces, but certainly does not eliminate, the risk of HIV infection.

Abstract
BACKGROUND The findings from observational studies, reviews and meta-analyses, supported by biological theories, that circumcised men appear less likely to acquire human immunodeficiency virus (HIV) has contributed to the recent ground swell of support for considering male circumcision as a strategy for preventing sexually acquired infection. We sought to elucidate and appraise the global evidence from published and unpublished studies that circumcision can be used as an intervention to prevent HIV infection. OBJECTIVES 1) To assess the evidence of an interventional effect of male circumcision for preventing acquisition of HIV-1 and HIV-2 by men through heterosexual intercourse 2) To examine the feasibility and value of performing individual person data (IPD) meta-analysis SEARCH STRATEGY We searched online for published and unpublished studies in The Cochrane Library (issue 2, 2002), MEDLINE (April 2002), EMBASE (February 2002) and AIDSLINE (August 2001). We also searched databases listing conference abstracts, scanned reference lists of articles and contacted authors of included studies. SELECTION CRITERIA We searched for randomized and quasi-randomized controlled trials of male circumcision or, in their absence, observational studies that compare acquisition rates of HIV-1 and HIV-2 infection in circumcised and uncircumcised heterosexual men. DATA COLLECTION AND ANALYSIS Independent reviewers selected studies, assessed study quality and extracted data. We stratified studies based on study design and on whether they included participants from the general population or high-risk groups (such as patients treated for sexually transmitted infections). We expressed findings as crude and adjusted odds ratios (OR) together with their 95% confidence intervals (CI) and conducted a sensitivity analysis to explore the effect of adjustment on study results. We investigated whether the method of circumcision ascertainment influenced study outcomes. MAIN RESULTS We identified no completed randomized controlled trials. Three randomized controlled trials are currently underway or commencing shortly. We found 34 observational studies: 16 conducted in the general population and 18 in high-risk populations. It seems unlikely that potential confounding factors were completely accounted for in any of the included studies. In particular, important risk factors, such as religion and sexual practices, were not adequately accounted for in many of the included studies. General population study results:The single cohort study (N = 5516) showed a significant difference in HIV transmission rates between circumcised and uncircumcised men [OR = 0.58; 95% CI: 0.36 to 0.96]. Results for the 14 cross-sectional studies were inconsistent, with point estimates for unadjusted odds ratios varying between 0.28 and 1.73. Six studies had statistically significant results, four in the direction of benefit and two in the direction of harm. The test for heterogeneity between the cross-sectional studies was highly significant (chi-square = 77.59; df = 13; P-value < 0.00001). Nine studies reported adjusted odds ratios with eight in the direction of benefit, ranging from 0.26 to 0.80. Use of adjusted results tended to show stronger evidence of an association although they remained heterogenous (chi-square = 75.2; df = 13; P-value < 0.00001). Only one case-control study was found (N = 51) which had a non-significant result [OR = 1.90; 95% CI: 0.50 to 7.20]. High-risk group study results:The four cohort studies identified found a protective effect from circumcision with point estimates for unadjusted odds ratios varying from 0.10 to 0.39. Two of these studies had statistically significant results. Two studies reported adjusted odds ratios, both protective with one being significant. The chi-square test for between-study heterogeneity was not significant (chi-square = 5.21; df = 3; P-value = 0.16). All eleven cross-sectional studies reporting unadjusted results found benefit from circumcision, eight of which had statistically significant results. Estimates of effnal studies reporting unadjusted results found benefit from circumcision, eight of which had statistically significant results. Estimates of effect varied from an unadjusted odds ratio of 0.10 to 0.66. Between-study heterogeneity was significant with the chi-square = 29.77; df = 10; P-value = 0.0009. Four of these studies reported adjusted odds ratios ranging from 0.20 to 0.59 and all were significant. One additional cross-sectional study only reported an adjusted odds ratio in the direction of benefit which was statistically significant. All three case-control studies found a protective effect of circumcision on HIV status, two being statistically significant. Point estimates varied from unadjusted odds ratios of 0.37 to 0.88. One reported an adjusted odds ratio showing a significant protective effect. Adverse effects:No studies reported on the adverse effects of circumcision. In most studies, circumcision had taken place during childhood or adolescence before the studies commenced. REVIEWER'S CONCLUSIONS We found insufficient evidence to support an interventional effect of male circumcision on HIV acquisition in heterosexual men. The results from existing observational studies show a strong epidemiological association between male circumcision and prevention of HIV, especially among high-risk groups. However, observational studies are inherently limited by confounding which is unlikely to be fully adjusted for. In the light of forthcoming results from RCTs, the value of IPD analysis of the included studies is doubtful. The results of these trials will need to be carefully considered before circumcision is implemented as a public health intervention for prevention of sexually transmitted HIV.

Abstract
OBJECTIVES To assess whether educational status is associated with HIV-1 infection in developing countries by conducting a systematic review of published literature. METHODS Articles were identified through electronic databases and hand searching key journals. Studies containing appropriately analysed individual level data on the association between educational attainment and HIV-1 status in general population groups were included. RESULTS Twenty-seven articles with appropriately analysed results from general population groups in developing countries were identified, providing information on only six countries. Large studies in four areas in Africa showed an increased risk of HIV-1 infection among the more educated, whilst among 21-year-old Thai army conscripts, longer duration of schooling was strongly protective against HIV infection. The association between education and schooling in Africa was stronger in rural areas and in older cohorts, but was similar in men and women. Serial prevalence studies showed little change in the association between schooling and HIV over time in Tanzania, but greater decreases in HIV prevalence among the more educated in Uganda, Zambia and Thailand. CONCLUSIONS In Africa, higher educational attainment is often associated with a greater risk of HIV infection. However, the pattern of new HIV infections may be changing towards a greater burden among less educated groups. In Thailand those with more schooling remain at lower risk of HIV infection.

Abstract
OBJECTIVES To quantify the association between prevalent or incident Herpes simplex virus type-2 (HSV2) infection and the incidence of HIV seroconversion among adults in the general population in rural Tanzania. STUDY POPULATION Adults aged 15-54 years sampled randomly from 12 rural communities in Mwanza Region, Tanzania and recruited to a randomized trial of improved treatment of sexually transmitted diseases. STUDY DESIGN Unmatched case-control study nested within trial cohort. METHODS Participants included 127 cases who seroconverted to HIV during the 2-year follow-up period and 636 randomly selected controls who remained HIV negative. Subjects were tested for HSV2 serology at baseline and follow-up, and associations between HIV and HSV2 were analysed with adjustment for socio-demographic and behavioural factors. RESULTS After adjusting for confounding factors, a strong association between HSV2 infection and HIV seroconversion was observed in men (test for trend: P < 0.001), with adjusted odds ratios (OR) of 6.12 [95% confidence interval (CI), 2.52-14.9] in those HSV2 positive at baseline, and 16.8 (95% CI, 6.06-46.3) in those acquiring HSV2 infection during follow-up. A weaker association was observed in women (tests for trend: P = 0.14), with adjusted OR of 1.32 (95% CI, 0.62-2.78) and 2.36 (95% CI, 0.81-6.84), respectively. Population attributable fractions of incident HIV infection due to HSV2 were estimated as 74% in men and 22% in women. CONCLUSIONS The results suggest that HSV2 plays an important role in the transmission of HIV infection in this population. There is an urgent need to identify effective HSV2 control measures in order to reduce HIV incidence in Africa.

Abstract
Over the past decade, numerous epidemiological studies have reported a significant association between lack of male circumcision and risk for HIV infection, leading to recommendations for male circumcision to be added to the armamentarium of effective HIV prevention strategies. We review the epidemiological data from studies that have investigated this association, including ecological, cross-sectional/case-control, and prospective studies. We discuss problematic issues in interpreting the epidemiological data, including the presence of other sexually transmitted infections, age of circumcision, and potential confounders such as religion, cultural practices, and genital hygiene. In addition, we review studies of biological mechanisms by which the presence of the foreskin may increase HIV susceptibility, data on risks associated with the circumcision procedure, and available data on the acceptability and feasibility of introducing male circumcision in societies where it is traditionally not practised. Although the evidence in support of male circumcision as an effective HIV prevention measure is compelling, residual confounding in observational studies cannot be excluded. Taken together with concerns over the potential disinhibiting effect of male circumcision on risk behaviour, and safety of the circumcision procedure, randomised trials of male circumcision to prevent HIV infection are recommended. An individual's choice to undergo male circumcision or a community's decision to promote the practice should be made in the light of the best available scientific evidence. More knowledge is required to assist individuals and communities in making those decisions. We conclude with recommendations for future research.

Abstract
BACKGROUND Because male circumcision has been linked to a lower risk of HIV infection, it is advocated tentatively as a possible preventive intervention. Most studies, however, have relied on men's self-reports of their circumcision status. GOAL To document varied techniques of male circumcision in one area of Kenya and the visible results. STUDY DESIGN Researchers interviewed men who had performed or undergone various forms of circumcision. They also did genital observations on a subsample of respondents. RESULTS All the men reported undergoing circumcision during adolescence, and most were able to tell which technique was used. According to the circumcisers, in type A, approximately 4 cm of the prepuce is removed; in type B, 1 to 2 cm of the prepuce and some of its inner surface are removed. Types A and B result in the same genital appearance. In type C, 1 to 2 cm of the prepuce and some of the inner surface are removed. The remaining prepuce is slit and suspended below the penile shaft. CONCLUSIONS Asking a man "Are you circumcised?" is not sufficient. Classifying his circumcision status requires both a genital examination and an understanding of the precise local surgical techniques used. Even in a small geographic area, considerable variety may exist in the techniques of cutting, removing, altering, or leaving different portions of the foreskin. Each variation may affect the transmission of HIV and other infections.

Abstract
OBJECTIVES To explore the role of male circumcision in the spread of HIV infection in four urban populations in sub-Saharan Africa. DESIGN AND METHODS A cross-sectional population based study was conducted in four cities in sub-Saharan Africa with different levels of HIV infection. HIV prevalence among adults was relatively low in Cotonou (Benin) and in Yaoundé (Cameroon), and exceeded 25% in Kisumu (Kenya) and in Ndola (Zambia). In each city, a random sample was taken of men and women aged 15-49 years from the general population. Consenting study participants were interviewed about their sociodemographic characteristics and their sexual behaviour, and were tested for HIV, herpes simplex virus type 2, syphilis, gonorrhoea and chlamydial infection. Men underwent a genital examination. RESULTS In Cotonou and in Yaoundé, the two low HIV prevalence cities, 99% of men were circumcised. In Kisumu 27.5% of men were circumcised, and in Ndola this proportion was 9%. In Kisumu, the prevalence of HIV infection was 9.9% among circumcised men and 26.6% among uncircumcised men. After controlling for socio-demographic characteristics, sexual behaviour and other sexually transmitted infections, the protective effect of male circumcision remained with an adjusted odds ratio of 0.26 (95% confidence interval = 0.12-0.56). In Ndola, the prevalence of HIV infection was 25.0% in circumcised men and 26.0% in uncircumcised men. The power was insufficient to adjust for any differences in sexual behaviour. CONCLUSIONS The differences in epidemic spread of HIV are likely to be due to differences in the probability of transmission of HIV during sexual exposure as well as differences in sexual behaviour. Male circumcision is one of the factors influencing the transmission of HIV during sexual intercourse, and this study confirms the population level association between HIV and lack of male circumcision, as well as a strong individual level association in Kisumu, the only city with sufficient power to analyze this association.

Abstract
BACKGROUND Male circumcision status is considered an important cofactor in the spread of HIV and sexually transmitted disease. There is limited evidence that male circumcision practices in Africa may be changing. GOAL To assess the determinants of male circumcision status in a traditionally noncircumcising ethnic group and to investigate the reasons for increasing acceptance of circumcision. METHODS Data from a factory workers study and a rural cohort study in northwest Tanzania were used to analyze the levels and determinants of male circumcision status and assess the reliability of self-reported data. Qualitative data from focus group discussions and in-depth interviews were obtained to ascertain norms and values in relation to male circumcision. RESULTS Male circumcision has become more popular in recent years, and 21% of 3,491 men reported themselves as circumcised. An increase in circumcision rates was observed in the rural cohort study during 1994 to 1997, though reporting inconsistencies are common. Circumcision rates were higher among men with higher levels of education and in Muslim men. Men are often circumcised in their late teens or twenties. The reasons for the increasing popularity of circumcision were investigated in group discussions and in-depth interviews. The most frequently mentioned reason was health-related; circumcision was thought to enhance penile hygiene, reduce sexually transmitted disease incidence, and improve sexually transmitted disease cure rates. CONCLUSION Male circumcision is becoming more popular among a traditionally noncircumcising ethnic group in Tanzania, especially in urban areas and among boys who have attended secondary schools.

Abstract
BACKGROUND The spread of heterosexual HIV in developing countries is heterogeneous. Factors that explain the wide diversity of HIV prevalences in different countries are undetermined. International aid organizations currently appear to be focusing activities mainly on women rather than on men. GOAL To identify critical determinants contributing to the high rates of heterosexual HIV transmission in developing countries through a review of studies investigating HIV per-act transmission rates, and to discuss how these factors might be prioritized through HIV-prevention interventions. STUDY DESIGN Studies investigating the per-act HIV transmission rate were identified through a MEDLINE search and a review of the abstracts of the Annual International AIDS Conferences. RESULTS When the summary mean per-act HIV transmission rates were calculated, the ratio of female-to-male HIV transmission in developing countries compared with that in the developed world was 341, whereas that for male-to-female transmission was 2.9. CONCLUSION Enhanced female-to-male HIV transmission in male core groups is a critical determinant of high-prevalence HIV epidemics among heterosexuals in developing countries. In addition to condom promotion, there is a need for an increased emphasis on HIV-prevention activities in men to decrease their susceptibility in developing countries, particularly in the countries most affected by the epidemic.

Abstract
There is growing epidemiological evidence from sub-Saharan Africa that male circumcision reduces the risk of HIV acquisition. We review the recent evidence of the protective effect on HIV and other sexually transmitted diseases, including discussion of possible biological mechanisms and highlighting the limitations of the observational studies on which these findings are based. We conclude by discussing the public health implications of these findings, including issues such as safety, acceptability, feasibility and cost-effectiveness of promoting male circumcision in African populations.

Abstract
The appropriate balance of HIV prevention and care activities depends on the specific epidemiology of HIV, including the stage of the epidemic; information about the cost-effectiveness of specific prevention interventions and treatment regimens; and the level of public resources available. In all countries, it is far less costly to prevent HIV than to treat people with AIDS. Once prevention needs are met, governments facing a severe epidemic who have additional resources should consider cost-effective treatment for people living with AIDS. The epidemiology of HIV provides two clear messages for prevention. First, it is imperative to act early in the epidemic, when HIV spreads exponentially. Viral load is highest during the first few months of infection, so that early in the epidemic a large proportion of those infected may be highly infectious. Second, it is crucial to target interventions initially to those with the highest-risk behavior. This will have the greatest impact on the number of new HIV infections prevented, as individuals with large numbers of sexual and needle-sharing partners who do not use condoms or clean injecting equipment are those most likely to become infected and then spread HIV. Changing the behavior of these individuals, even if only a relatively few members of society, is essential to curbing the epidemic.
