A comparison of sexual risk behaviours and HIV seroprevalence among circumcised and uncircumcised men before and after implementation of the safe male circumcision programme in Uganda

HIV status and knowledge of cervical cancer among women in Ghana

BACKGROUND

Cervical cancer remains a disease of significant concern to women's health. The aim of this study was to identify predictors of knowledge of cervical cancer among women living with HIV and those with negative or unknown HIV status at the Cape Coast Teaching Hospital (CCTH).

METHODS

This study was based on a larger hospital-based analytical cross-sectional study conducted at the antiretroviral therapy (ART) and gynaecology clinics of the Cape Coast Teaching Hospital in Ghana. Participants were women living with HIV (WLHIV) and women without HIV or whose status was unknown, aged 25 to 65 years, seeking healthcare. Data were collected with a questionnaire and analysed using frequencies, percentages, Chi-square test, binary logistic regression and multivariate analysis.

RESULTS

The mean age was 39.5 years (± 9.8) and 47.2 years (± 10.7) for women without or unknown HIV and WLHIV, respectively. HIV-negative/unknown women were mostly nulligravida (76%) and nullipara (69%), while WLHIV mostly had pregnancies (76%) and children (84%) in excess of seven. Knowledge of cervical cancer was statistically significantly associated with HIV status (X2 = 75.65; P-value = 0.001). The odds of having knowledge of cervical cancer for women considered to be negative/unknown for HIV were about three times (AOR = 3.07; 95% CI = 1.47, 6.41) higher than their compatriots with HIV. Women with post-secondary/tertiary (AOR = 4.45; 95% CI = 2.11, 9.35) education had significantly higher odds of having knowledge of cervical cancer than those with no education or those with just primary education.

CONCLUSIONS

To improve knowledge of cervical cancer among women, an intentionally structured health education programme is needed, particularly for WLHIV, those with lower levels of education and the unemployed.

Age-incidence and prevalence of HIV among intact and circumcised men: an analysis of PHIA surveys in Southern Africa

The study investigates the statistical relationship between male circumcision and HIV prevalence in Africa, in the context of the Voluntary Medical Male Circumcision (VMMC) campaigns in place since 2008. Data from the Population-based HIV Impact Assessment (PHIA) surveys conducted in African countries in 2017-2018 were utilized. Six countries with high HIV prevalence, low traditional circumcision and large VMMC programs were selected: Eswatini, Lesotho, Malawi, Namibia, Zambia, Zimbabwe. The statistical analysis investigated the relative risk (RR) of HIV prevalence by circumcision status (circumcised vs intact) among men age 20-59, and the age-incidence of HIV in the two groups among men age 20-49, defined as the linear-logistic slope of the relationship between prevalence and age. Results show that the standardized RR was not different from 1 at older ages (50-59): RR = 0.923, 95% CI = 0.769-1.108, P = 0.390. Furthermore, the age-incidence was at least as high or higher among the circumcised groups than among the intact groups. The standardized RR was lower than 1 at younger ages, and this could be explained by selection biases. HIV prevalence at age 40-59 (27.3%) was also the same in the four groups of circumcision status (intact, traditional, medical, unknown). Results matched earlier observations made in South Africa that circumcised and intact men had similar levels of HIV infection. The study questions the current strategy of large scale VMMC campaigns to control the HIV epidemic. These campaigns also raise a number of ethical issues.

Male Circumcision and Genital Human Papillomavirus (HPV) Infection in Males and Their Female Sexual Partners: Findings From the HPV Infection and Transmission Among Couples Through Heterosexual Activity (HITCH) Cohort Study

BACKGROUND

Previous studies examining the association between male circumcision (MC) and human papillomavirus (HPV) infections have reported inconsistent results. We used data from the HPV Infection and Transmission Among Couples Through Heterosexual Activity (HITCH) cohort study to examine the association between MC and HPV infections in males and their female sexual partners.

METHODS

We enrolled monogamous couples in a longitudinal study between 2005 and 2011 in Montreal, Canada. We used logistic and Poisson regression models with propensity score adjustment to estimate odds ratios (ORs) and rate ratios for the association between MC and the prevalence, transmission, and clearance of HPV infections.

RESULTS

Four hundred thirteen couples were included in our study. The prevalence OR for the association between MC and baseline infections was 0.81 (95% confidence interval [CI], .56-1.16) in males and 1.05 (95% CI, .75-1.46) in females. The incidence rate ratio for infection transmission was 0.59 (95% CI, .16-2.20) for male-to-female transmission and 0.77 (95% CI, .37-1.60) for female-to-male transmission. The clearance rate ratio for clearance of infections was 0.81 (95% CI, .52-1.24).

CONCLUSIONS

We found little evidence of an association between MC and HPV infection prevalence, transmission, or clearance in males and females. Further longitudinal couple-based studies are required to investigate this association.

Understanding the Evolving Role of Voluntary Medical Male Circumcision as a Public Health Strategy in Eastern and Southern Africa: Opportunities and Challenges

PURPOSE OF REVIEW

Voluntary male medical circumcision (VMMC) has been a cornerstone of HIV prevention in Eastern and Southern Africa (ESA) and is credited in part for declines in HIV incidence seen in recent years. However, these HIV incidence declines change VMMC cost-effectiveness and how it varies across populations.

RECENT FINDINGS

Mathematical models project continued cost-effectiveness of VMMC in much of ESA despite HIV incidence declines. A key data gap is how demand generation cost differs across age groups and over time as VMMC coverage increases. Additionally, VMMC models usually neglect non-HIV effects of VMMC, such as prevention of other sexually transmitted infections and medical adverse events. While small compared to HIV effects in the short term, these could become important as HIV incidence declines. Evidence to date supports prioritizing VMMC in ESA despite falling HIV incidence. Updated modeling methodologies will become necessary if HIV incidence reaches low levels.

Association between medical male circumcision and HIV risk compensation among heterosexual men: a systematic review and meta-analysis

Background

Medical male circumcision (MMC) reduces HIV infection among heterosexual men. There are concerns MMC might prompt higher-risk sexual behaviours because of lower self-perceived risk of HIV infection. We reviewed the published literature to examine associations between MMC and both condom use and number of sex partners among heterosexual men.

Methods

In this systematic review and meta-analysis, we searched PubMed, Embase, and the Cochrane Library for studies published before Nov 15, 2020. Interventional and observational studies were included if they contained original quantitative data describing the association between MMC and condom use or number of sex partners among heterosexual men. We excluded data from men whose circumcisions were ritual or religious and data from men who have sex with men. We extracted odds ratios (ORs) and 95% CIs for the associations between MMC and condomless sex and MMC and multiple sex partners directly from the publications if available, selecting adjusted ORs when provided; when necessary, we calculated ORs and 95% CIs using original study data provided in the publication. We used the Mantel-Haenszel random effects model to calculate pooled ORs and 95% CIs.

Findings

Our search yielded 3035 results, of which 471 were duplicates and 2537 did not meet the inclusion criteria. From the remaining 27 eligible studies, we identified 99 292 men from 31 independent population samples. 24 studies were done in Africa. We found no statistically significant associations between MMC and condomless sex (OR 0·91, 95% CI 0·80–1·05; k=30; I²=88·7%) or multiple sex partners (1·02, 0·88–1·18; k=27; I²=90·1%). No associations between MMC and condomless sex or multiple sexual partners were found in any subgroup analyses by study design, income of country, age, recruitment setting, circumcision assessment, circumcision prevalence, and risk of publication bias.

Interpretation

The promotion of circumcision as an HIV preventive measure does not appear to increase higher-risk sexual behaviours in heterosexual men. Ongoing sexual health education should be maintained as a vital component of effective MMC programmes.

Understanding the linkages between male circumcision and multiple sexual partnership among married Ghanaian men: Analysis of data from the 2014 Ghana demographic and health survey

INTRODUCTION

This current study sought to investigate the association between male circumcision status and engaging in multiple sexual partnership among men in Ghana.

METHODS

Data from this study come from the men's file of the 2014 Ghana demographic and health survey. Both descriptive and inferential statistics were conducted among 1, 948 men and the level of statistical significance was pegged at p < 0.05.

RESULTS

Results revealed that men who have been circumcised were more likely to engage in multiple sexual partnership (AOR = 3.36; CI:1.14-9.89), compared to those who have not been circumcised. With the covariates, men with primary level of education were more likely to have multiple sexual partners (AOR = 2.01; CI:1.10-3.69), compared to those with no education. With wealth status, men with richest (AOR = 2.27; CI:1.04-4.97), richer (AOR = 2.05; CI: 1.03-4.08), and middle wealth status (AOR = 1.83; CI:1.01-3.34) had the highest likelihood of having multiple sexual partners, compared to those with poorest wealth status. Conversely, men who professed the Islamic faith were less likely to engage in multiple sexual partnership (AOR = 0.58; CI: 0.36-0.94), compared to Christians. Similarly, men who resided in the Brong Ahafo (AOR = 0.51; CI: 0.26-0.99), Upper East (AOR = 0.41; CI:0.19-0.89), and Ashanti regions (AOR = 0.39; CI: 0.20-0.78) were less likely to engage in multiple sexual partnership.

CONCLUSION

Based on the current findings, educational campaigns by stakeholder groups (e.g., Ministry of Health in collaboration with the National Commission on Civic Education, civil society, educational institutions) should sensitize the sexually active population at the community level to consistently use condoms, especially when they have multiple sexual partners, even when a man is circumcised. Campaign messages must clearly emphasize that male circumcision should not substitute precautionary measures such as delay in the onset of sexual relationships, averting penetrative sex, reducing the number of sexual partners as well as correct and consistent use of male or female condoms regardless one's social standing.

Mapping male circumcision for HIV prevention efforts in sub-Saharan Africa

BACKGROUND

HIV remains the largest cause of disease burden among men and women of reproductive age in sub-Saharan Africa. Voluntary medical male circumcision (VMMC) reduces the risk of female-to-male transmission of HIV by 50-60%. The World Health Organization (WHO) and Joint United Nations Programme on HIV/AIDS (UNAIDS) identified 14 priority countries for VMMC campaigns and set a coverage goal of 80% for men ages 15-49. From 2008 to 2017, over 18 million VMMCs were reported in priority countries. Nonetheless, relatively little is known about local variation in male circumcision (MC) prevalence.

METHODS

We analyzed geo-located MC prevalence data from 109 household surveys using a Bayesian geostatistical modeling framework to estimate adult MC prevalence and the number of circumcised and uncircumcised men aged 15-49 in 38 countries in sub-Saharan Africa at a 5 × 5-km resolution and among first administrative level (typically provinces or states) and second administrative level (typically districts or counties) units.

RESULTS

We found striking within-country and between-country variation in MC prevalence; most (12 of 14) priority countries had more than a twofold difference between their first administrative level units with the highest and lowest estimated prevalence in 2017. Although estimated national MC prevalence increased in all priority countries with the onset of VMMC campaigns, seven priority countries contained both subnational areas where estimated MC prevalence increased and areas where estimated MC prevalence decreased after the initiation of VMMC campaigns. In 2017, only three priority countries (Ethiopia, Kenya, and Tanzania) were likely to have reached the MC coverage target of 80% at the national level, and no priority country was likely to have reached this goal in all subnational areas.

CONCLUSIONS

Despite MC prevalence increases in all priority countries since the onset of VMMC campaigns in 2008, MC prevalence remains below the 80% coverage target in most subnational areas and is highly variable. These mapped results provide an actionable tool for understanding local needs and informing VMMC interventions for maximum impact in the continued effort towards ending the HIV epidemic in sub-Saharan Africa.

An assessment of sexual risk behaviours among circumcised and uncircumcised men before and after the implementation of the safe male circumcision programme in Botswana

HIV/AIDS prevalence is still high in Botswana. The main aim of this study was to assess and compare sexual risk behaviours of circumcised and uncircumcised men before and after the launch of the safe male circumcision programme. Data used for analyses were derived from the 2008 and 2013 Botswana AIDS Impact Surveys. Modified Poisson regression analysis was used to obtain prevalence ratios (PR) as measures of association between circumcision status and multiple sexual partners, transactional sex, inconsistent condom use and intergenerational sex. The proportion of circumcised men increased two times between 2008 (12.5%) and 2013 (25.2%). Prevalence of multiple sexual partnerships was high among uncircumcised than circumcised (54.6% vs. 46.4%) men in 2008, but in 2013 after the introduction of the SMC programme it was slightly high among circumcised men than uncircumcised men (23.2 vs. 21.8%). In the adjusted analyses, being circumcised was significantly associated with having multiple sexual partners (2008=adjusted PR=1.31, CI=1.10-1.57; 2013= adjusted PR=1.12, CI=1.01-1.41) and transactional sex (2008=adjusted PR=1.98, CI=1.26-3.11; 2013=adjusted PR=1.60, CI=1.09-1.22) for both survey periods. These results indicate the need to continuously sensitise and encourage men to stop multiple sexual partnerships and transactional sex. Moreover, there is need to encourage all men to use condoms consistently.

Does Incident Circumcision Lead to Risk Compensation? Evidence From a Population Cohort in KwaZulu-Natal, South Africa

BACKGROUND

Voluntary medical male circumcision reduces men's risk of HIV acquisition and may thus increase HIV risk-related sexual behaviors through risk compensation. We analyze longitudinal data from one of Africa's largest population cohorts using fixed-effects panel estimation to measure the effect of incident circumcision on sexual behaviors.

SETTING

KwaZulu-Natal, South Africa.

METHODS

An open population cohort of men was followed from 2009 to 2015. Men self-reported their circumcision status and sexual behavior annually. We used linear regression models with individual-level fixed effects to measure the effect of incident circumcision on recent sex (past 12 months) and sexual behaviors that increase HIV risk (not using a condom at last sex, never using condoms with the most recent sexual partner, concurrent sexual partners at present, and multiple sexual partners in the past 12 months). We controlled for potential time-varying confounders: calendar year, age, education, and sexual debut.

RESULTS

The 5127 men in the cohort had a median age of 18 years (interquartile range 16-24) at cohort entry. Over the study period, almost 1 in 5 of these men (19.4%) became newly circumcised. Incident circumcision affected neither recent sex [percentage point (PP) change 0.0, 95% confidence interval: -1.2 to 1.3] nor sexual behaviors that increase HIV risk (PP -1.6, 95% confidence interval: -4.5 to 1.4).

CONCLUSIONS

The data from this study strongly reject the hypothesis that circumcision affects sexual risk-taking. Risk compensation should not serve as an argument against increased and accelerated scale-up of circumcision in this and similar communities in South Africa.

Sexual risk behaviors following circumcision among HIV-positive men in Rakai, Uganda

OBJECTIVE

To determine whether circumcision of HIV-positive men is associated with increased subsequent sexual risk behaviors which may place their female partners at risk.

METHODS

Newly circumcised and uncircumcised HIV-positive men in the Rakai Community Cohort Study were followed from baseline (July 2013-January 2015) to determine trend in sexual risk behaviors and association of circumcision with subsequent sexual risk behaviors at follow up (February 2015-September 2016). Risk behaviors included sexual activity, alcohol before sex, transactional sex, multiple sex partners, casual sex partners, and inconsistent condom use with casual partners. The association was evaluated using modified Poisson regression, and sensitivity analyses were performed after multiple imputation with chained equations for missing data.

RESULTS

We identified 538 eligible men, of whom 113(21.0%) were circumcised at baseline and 425(79.0%) were uncircumcised. Men in fishing communities were more likely to be circumcised (p = 0.032) as well as those exposed to targeted HIV messaging (p < 0.001). Overall, 188(34.9%) men were lost to follow up and most were uncircumcised (p = 0.020). Among those followed up, behaviors remained largely unchanged with no differences by circumcision status. Transactional sex appeared to be associated with circumcision in unadjusted analyses (PR = 1.58, 95%CI = 1.01,2.48; p = 0.045, p = 0.05) and adjusted analyses (adj.PR = 1.54, 95%CI = 1.06,2.23; p = 0.022). However, the association was no longer significant in sensitivity analyses after accounting for loss to follow up (adj.PR = 1.43, 95%CI = 0.98,2.08; p = 0.066). No association with circumcision was observed for other sexual risk behaviors.

CONCLUSION

We found no association between circumcision of HIV-positive men and subsequent sexual risk behavior.

Examination of short and long term complications of thermocautery, plastic clamping, and surgical circumcision techniques

Objective:

In this study, thermocautery, plastic clamping, and conventional (open surgical) circumcision techniques were compared in terms of their complications.

Methods:

Male patients who underwent circumcisions between May 2014 and May 2015 in two separate pediatric surgery clinics were retrospectively analyzed using the hospital registry system. These patients were evaluated in terms of age, accompanying pathologies, anesthesia techniques, complication rates, duration of surgery, and circumcision techniques. A statistical analysis of the data was performed, with a P<0.05 considered to be statistically significant.

Results:

The patients were divided into three groups according to the circumcision method: conventional surgical circumcision (n=833), thermocautery (n=1011), and plastic clamp (n=218). Complications were observed in 21 cases (1%): bleeding (11), infection (2), trapped penis (6), meatitis (1), and scrotal injury (1). There were significantly fewer complications in the thermocautery technique when compared to the clamping and surgical circumcision techniques. The plastic clamping and thermocautery techniques were superior to a surgical circumcision in terms of the operation time.

Conclusion:

The thermocautery circumcision technique can be used easily in both the operating theatre and in designated circumcision rooms, with a lower complication rate, when compared to plastic clamping and surgical circumcisions.

Optimizing Prevention of HIV and Unplanned Pregnancy in Discordant African Couples

BACKGROUND

Dual method use, which combines condoms with a more effective modern contraceptive to optimize prevention of HIV and unplanned pregnancy, is underutilized in high-risk heterosexual couples.

MATERIALS AND METHODS

Heterosexual HIV-discordant Zambian couples were enrolled from couples' voluntary HIV counseling and testing services into an open cohort with 3-monthly follow-up (1994-2012). Relative to dual method use, defined as consistent condom use plus modern contraception, we examine predictors of (1) condom-only use (suboptimal pregnancy prevention) or (2) modern contraceptive use with inconsistent condom use (effective pregnancy prevention and suboptimal HIV prevention).

RESULTS

Among 3,049 couples, dual method use occurred in 28% of intervals in M+F- and 23% in M-F+, p < 0.01; condom-only use in 56% in M+F- and 61% in M-F+, p < 0.01; and modern contraceptive use with inconsistent condom use in 16% regardless of serostatus. Predictors (p < 0.05) of condom-only use included the man being HIV+ (adjusted hazard ratio, aHR = 1.15); baseline oral contraceptive pill (aHR = 0.76), injectable (aHR = 0.48), or implant (aHR = 0.60) use; woman's age (aHR = 1.04 per 5 years) and lifetime number of sex partners (aHR = 1.01); postpartum periods (aHR = 1.25); and HIV stage of the index partner III/IV versus I (aHR = 1.10). Predictors (p < 0.05) of modern contraceptive use with inconsistent condom use included woman's age (aHR = 0.94 per 5 years) and HIV+ male circumcision (aHR = 1.51), while time-varying implant use was associated with more consistent condom use (aHR = 0.80).

CONCLUSIONS

Three-quarters of follow-up intervals did not include dual method use. This highlights the need for counseling to reduce unintended pregnancy and HIV transmission and enable safer conception.

Evidence that promotion of male circumcision did not lead to sexual risk compensation in prioritized Sub-Saharan countries

Background

WHO and UNAIDS prioritized 14 eastern and southern African countries with high HIV and low male circumcision prevalence for a voluntary medical male circumcision (VMMC) scale-up in 2007. Because circumcision provides only partial protection against HIV infection to men, the issue of possible risk compensation in response to VMMC campaigns is of particular concern. In this study, we looked at population-level survey data from the countries prioritized by WHO for a VMMC scale-up. We compared the difference in sexual risk behaviours (SRB) between circumcised and uncircumcised men before and after the WHO’s official VMMC promotion.

Materials and methods

Ten countries (Kenya, Lesotho, Malawi, Mozambique, Namibia, Rwanda, Tanzania, Uganda, Zambia and Zimbabwe) participating in the WHO’s VMMC scale-up had available data from the Demographic and Health Surveys (DHS). We used cumulative-link mixed models to investigate interactions between survey period and circumcision status in predicting SRB, in order to evaluate whether the difference between the behavior of the two groups changed before and after the scale-up, while controlling for socio-demographic and knowledge-related covariates. The main responses were condom use at last sex and number of non-cohabiting sexual partners, both in the last 12 months.

Results

There was little change in condom use by circumcised men relative to uncircumcised men from before the VMMC scale up to after the scale up. The relative odds ratio is 1.06 (95% CI, 0.95–1.18; interaction P = 0.310). Similarly, there was little change in the number of non-cohabiting partners in circumcised men (relative to uncircumcised men): the relative odds ratio of increasing the number of partners is 0.95 (95% CI, 0.86–1.05; interaction P = 0.319). Age, religion, education, job, marital status, media use and HIV knowledge also showed statistically significant association with the studied risk behaviours. We also found significant differences among countries, while controlling for covariates.

Conclusions

Overall, we find no evidence of sexual risk compensation in response to VMMC campaigns in countries prioritized by WHO. Changes in relative partner behaviour and the relative odds of condom use were small (and of uncertain sign). In fact, our estimates, though not significant, both suggest slightly less risky behavior. We conclude that sexual risk compensation in response to VMMC campaigns has not been a serious problem to date, but urge continued attention to local context, and to promulgating accurate messages about circumcision within and beyond the VMMC context.

Discourses of masculinity, femininity and sexuality in Uganda's Stand Proud, Get Circumcised campaign

This paper analyses discourses of masculinity, femininity and sexuality in Stand Proud, Get Circumcised, a public health campaign promoting circumcision as an HIV-prevention strategy in Uganda. The campaign includes posters highlighting the positive reactions of women to circumcised men, and is intended to support the national rollout of voluntary medical male circumcision. We offer a critical discourse analysis of representations of masculinity, femininity and sexuality in relation to HIV prevention. The campaign materials have a playful feel and, in contrast to ABC (Abstain, Be faithful, Use condoms) campaigns, acknowledge the potential for pre-marital and extra-marital sex. However, these posters exploit male anxieties about appearance and performance, drawing on hegemonic masculinity to promote circumcision as an idealised body aesthetic. Positioning women as the campaign's face reasserts a message that women are the custodians of family health and simultaneously perpetuates a norm of estrangement between men and their health. The wives' slogan, 'we have less chance of getting HIV', is misleading, because circumcision only directly prevents female-to-male HIV transmission. Reaffirming hegemonic notions of appearance- and performance-based heterosexual masculinity reproduces existing unsafe norms about masculinity, femininity and sexuality. In selling male circumcision, the posters fail to promote an overall HIV-prevention message.

Pros and cons of circumcision: an evidence-based overview

Based on three large randomized controlled trials (RCTs) conducted in Africa, it can clearly be stated that circumcision lowers the risk of infection with the human immunodeficiency virus (HIV) and some sexually transmitted infections (STIs) among males in settings of high HIV and STI endemicity. Similar effects on STI risk may exist for females, although this may result from an indirect effect of decreasing risk of infection among male partners. It is unknown whether circumcision prevents HIV acquisition in men who have sex with men (MSM), although there might be a protective effect for men who engage mainly in insertive anal intercourse. When the effects of adult circumcision on sexual function and satisfaction of men are examined, high-quality evidence strongly supports lack of harm. Whether circumcision alters sexual satisfaction of female partners is not known as fewer and smaller studies reported conflicting results. Circumcision rarely causes serious complications if practiced by trained practitioners, in a sterile setting, and with a proper follow-up. These conclusions are limited by the lack of high-quality data from areas outside of Africa. RCTs have not been conducted to assess the effects of circumcising infants or MSM. Circumcision has well-proven benefits for people residing in areas with high prevalence of STIs, including HIV, and is not unethical for those who choose to be circumcised or have their children circumcised on religious, social, or cultural grounds. For many others, a definite pro or con recommendation, based on a risk-benefit ratio, cannot be made.
