Abstract
Reducing multiple and concurrent partnerships has been identified as a priority in generalised HIV epidemics, yet developing successful interventions to bring about such behaviour change has proven challenging. We offered a three-session intervention aimed to improve couple relationship quality and address HIV risk factors, particularly concurrent sexual partnerships (CSP), in a peri-urban community of Kampala, Uganda. Before launching the intervention, a different group of community members participated in eight single-gender focus group discussions (FGDs) which explored issues of couple relationship quality and satisfaction. Findings from the FGDs guided the intervention. All 162 couples invited to the intervention completed a survey pre- and post-intervention. In FGDs, women and men discussed challenges faced in their relationships, including pervasive dissatisfaction, financial constraints, deception and lack of trust, poor communication, lack of sexual satisfaction, and concurrent sexual partnerships. A difference-in-difference analysis showed no measurable impact of the intervention on relationship quality or sexual risk behaviours over a six-month follow-up among 183 individuals who participated in the intervention, although many stated in response to open-ended questions that they had experienced positive relationship changes. Qualitative findings suggest high demand for couple-focused interventions but also reveal many individual-, couple-, community- and structural-level factors which contribute to women and men seeking concurrent sexual partnerships. More intensive interventions may be needed to overcome these barriers to behaviour change and reduce HIV risk. These findings also raise questions about how to interpret divergent qualitative and quantitative data, a topic which has received little attention in the literature.

Abstract
INTRODUCTION Sexual activity is an essential human need and an important predictor of other aspects of human life. A literature review was conducted to investigate whether sexual abstinence in young and middle-aged men is generally considered a deliberate, healthy behavior and whether it has other causes and consequences. AIM To review the prevalence and factors associated with sexual abstinence in young (10-24 years) and middle-aged (25-59 years) men. METHODS Studies were retrieved from Science Direct, PubMed, and EBSCOhost published from 2008 to 2019. The selection criteria were original population- or community-based articles, published in the English language, on sexual abstinence, and in young and middle-aged men. MAIN OUTCOME MEASURE This article reviewed the literature on the proportions of and factors associated with sexual abstinence in young and middle-aged men. RESULTS A total of 13,154 studies were retrieved, from which data were extracted for 37 population- or community-based studies. The prevalence of sexual abstinence varied from 0% to 83.6% in men younger than 60 years. The prevalence of primary sexual abstinence was 3.4%-83.3% for young men and 12.5%-15.5% for middle-aged men. The prevalence of secondary abstinence for young men ranged from 1.3% to 83.6%, while for middle-aged men, it was from 1.2% to 67.7%. The prevalence of sexual abstinence decreased with increasing age in young men but increased with increasing age in middle-aged men. The significant factors reported were age, single status, poor relationships, low socioeconomic status, sex education, religious practices, caring and monitoring parents, and not using alcohol, cigarettes, or drugs. Although the variations in findings from different studies can be explained by different regions and cultures, the information cannot be generalized worldwide because of a lack of studies in Asian and Australian populations. CLINICAL IMPLICATIONS The studies on sexual abstinence in the future should use a consistent and standard definition, cover all sexual behaviors, and investigate all related factors. STRENGTH & LIMITATIONS The restricted timeframe (2008-2019), English language, availability of full text, and variability in definition and time duration may be the sources of bias. CONCLUSION Young men had higher proportions of sexual abstinence than middle-aged men, and age, unavailability of a partner, lower educational levels, low socioeconomic status, conservative and religious conditions, and no or less knowledge about sexually transmitted infections were common predictors of sexual abstinence in most of the men. Although determinants of sexual abstinence were identified, further investigation of biological factors in men younger than 60 years is needed. Irfan M, Hussain NHN, Noor NM, et al.

Abstract
BACKGROUND Approximately 70% of global HIV infections are located in sub-Saharan Africa, and the prevalence of HIV infection in Kenya remains high. OBJECTIVES This study examined the association between client type (general population, commercial sex worker [CSW], or truck driver) and consistent condom use with steady and unsteady partners. METHODS Self-reported data included in the Kenyan Ministry of Health 2010-2011 National HIV Testing and Counseling Registry were used (n=11,567). Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained using logistic regression. RESULTS After adjustment, CSWs and truck drivers had decreased odds of consistent condom use with steady partners compared to the general population (OR=0.52; 95% CI: 0.41-0.67 and OR=0.29; 95% CI: 0.13-0.63; respectively). CSWs had 1.95 times the odds of consistent condom use (95% CI: 1.58-2.42) and truck drivers had 0.64 times the odds of consistent condom use with unsteady partners (95% CI: 0.45-0.91) compared to the general population. CONCLUSION Although CSWs consistently use condoms with their unsteady partners, truck drivers do not consistently use condoms with any partners. Future HIV prevention efforts should target CSWs and truck drivers to increase consistent condom use with all partners. Such efforts may decrease the prevalence of HIV in Kenya.

Abstract
Introduction New infections of Human Immunodeficiency Virus (HIV) remain a big problem in many countries. Different interventions have been implemented to improve the general knowledge of HIV, with the hypothesis that increasing HIV knowledge will reduce risky sexual behavior (RSB). However, HIV knowledge may not necessarily reduce RSB. This study explores HIV knowledge and its effect on RSB. Methods The study used data from the 2005 and 2010 Rwanda Demographic and Health Surveys to analyze the association between HIV risk factors and two types of RSB (having two or more partners in the past 12 months; and among those with two or more partners, not using a condom at last sex) and the association between HIV knowledge and those RSB. Multivariate logistic regression was used to determine predictors of RSB. Results Among 2,773 men in 2005 and 3,772 men in 2010, 5% and 7% respectively reported having two or more sexual partners. Among them, 93% in 2005 and 74% in 2010 did not use a condom at the last sex. Between 2005 and 2010, knowledge of the protective effect of having just one uninfected faithful partner, and basic knowledge of HIV decreased. Knowledge of the protective effect of using condoms increased from 90% to 94%. However, HIV knowledge was not associated with either type of RSB. Conclusion In setting up policies and strategies related to HIV prevention, policymakers should consider that focusing on HIV knowledge is not sufficient in itself.

Abstract
PURPOSE Suboptimal sexual and reproductive health (SRH) increases morbidity, mortality, and gender inequity and slows development. In Uganda, youths represent 20% of the population, and the burden of sexually transmitted infections (STIs), including human immunodeficiency virus (HIV), is substantial. METHODS We analyzed survey data collected using the lot quality assurance sampling (LQAS) technique from two time periods, 2003-2004 and 2012. We assessed knowledge, behaviors, and access to SRH services of youths aged 15-24 years. Using logistic regression, we examined factors associated with these indicators. RESULTS All indicators have improved between the early and later time period. Youths knowing where to get HIV tests increased from <40% to 80% (both sexes); the number of youths reporting ever having an HIV test increased from 8% to 48% (males) and 10% to 64% (females). Knowledge of other STIs improved but remains low; only half of respondents know signs and symptoms of STIs, and less than half know what action to take when infected. In the late period, 85% of female youths, compared with 93% of males reported knowing where to obtain condoms. The proportion of youths reporting sexual debut before age 15 years decreased, less so for males than that for females. Increased age and level of education are associated with positive change for most indicators. CONCLUSIONS Over the last decade, progress has been made toward improving the SRH of young people in Uganda. Further efforts are required to ensure universal access and sufficient health education to facilitate the continued improvement of safe sexual behaviors among youth aged 15-24 years.

Abstract
For the past 25 years, the Medical Research Council/Uganda Virus Research Institute Uganda Research Unit on AIDS has conducted research on HIV-1, coinfections and, more recently, on non-communicable diseases. Working with various partners, the research findings of the Unit have contributed to the understanding and control of the HIV epidemic both in Uganda and globally, and informed the future development of biomedical HIV interventions, health policy and practice. In this report, as we celebrate our silver jubilee, we describe some of these achievements and the Unit's multidisciplinary approach to research. We also discuss the future direction of the Unit; an exemplar of a partnership that has been largely funded from the north but led in the south.

Study: a cluster randomized controlled trial to assess the impact of a community mobilization intervention to prevent violence against women and reduce HIV risk in Kampala, Uganda. BMC Med 2014; 12:122.

Abstract
BACKGROUND Intimate partner violence (IPV) and HIV are important and interconnected public health concerns. While it is recognized that they share common social drivers, there is limited evidence surrounding the potential of community interventions to reduce violence and HIV risk at the community level. The SASA! study assessed the community-level impact of SASA!, a community mobilization intervention to prevent violence and reduce HIV-risk behaviors. METHODS From 2007 to 2012 a pair-matched cluster randomized controlled trial (CRT) was conducted in eight communities (four intervention and four control) in Kampala, Uganda. Cross-sectional surveys of a random sample of community members, 18- to 49-years old, were undertaken at baseline (n = 1,583) and four years post intervention implementation (n = 2,532). Six violence and HIV-related primary outcomes were defined a priori. An adjusted cluster-level intention-to-treat analysis compared outcomes in intervention and control communities at follow-up. RESULTS The intervention was associated with significantly lower social acceptance of IPV among women (adjusted risk ratio 0.54, 95% confidence interval (CI) 0.38 to 0.79) and lower acceptance among men (0.13, 95% CI 0.01 to 1.15); significantly greater acceptance that a woman can refuse sex among women (1.28, 95% CI 1.07 to 1.52) and men (1.31, 95% CI 1.00 to 1.70); 52% lower past year experience of physical IPV among women (0.48, 95% CI 0.16 to 1.39); and lower levels of past year experience of sexual IPV (0.76, 95% CI 0.33 to 1.72). Women experiencing violence in intervention communities were more likely to receive supportive community responses. Reported past year sexual concurrency by men was significantly lower in intervention compared to control communities (0.57, 95% CI 0.36 to 0.91). CONCLUSIONS This is the first CRT in sub-Saharan Africa to assess the community impact of a mobilization program on the social acceptability of IPV, the past year prevalence of IPV and levels of sexual concurrency. SASA! achieved important community impacts, and is now being delivered in control communities and replicated in 15 countries. TRIAL REGISTRATION ClinicalTrials.gov #NCT00790959.

Abstract
INTRODUCTION In an HIV/AIDS epidemic driven primarily by heterosexual transmission, it is important to have an understanding of the human sexual behaviour patterns that influence transmission. We analysed the distribution and predictors of within-partnership sexual behaviour and condom use in rural Zimbabwe and generated parameters for use in future modelling analyses. METHODS A population-based cohort was recruited from a household census in 12 communities. A baseline survey was carried out in 1998-2000 with follow-up surveys after 3 and 5 years. Statistical distributions were fitted to reported within-partnership numbers of total, unprotected and protected sex acts in the past two weeks. Multilevel linear and logistic regression models were constructed to assess predictors of the frequency of unprotected sex and consistent condom use. RESULTS A normal distribution of ln(sex acts+1) provided the best fit for total and unprotected sex acts for men and women. A negative binomial distribution applied to the untransformed data provided the best fit for protected sex acts. Condom use within partnerships was predominantly bimodal with at least 88% reporting zero or 100% use. Both men and women reported fewer unprotected sex acts with non-regular compared to regular partners (men: 0.26 fewer every two weeks (95% confidence interval 0.18-0.34); women: 0.16 (0.07-0.23)). Never and previously married individuals reported fewer unprotected sex acts than currently married individuals (never married men: 0.64 (0.60-0.67); previously married men: 0.59 (0.50-0.67); never married women: 0.51 (0.45-0.57); previously married women: 0.42 (0.37-0.47)). These variables were also associated with more consistent condom use. DISCUSSION We generated parameters that will be useful for defining transmission models of HIV and other STIs, which rely on a valid representation of the underlying sexual network that determines spread of an infection. This will enable a better understanding of the spread of HIV and other STDs in this rural sub-Saharan population.

Abstract
Background This paper analyzes how different types of Human immunodeficiency virus (HIV) knowledge influences condom use across the sexes. Methods The empirical work was based on a household survey conducted among 1979 households of a representative group of stallholders in Lagos, Nigeria in 2008. Condom use during last sexual intercourse was analyzed using a multivariate model corrected for clustering effects. The data included questions on socioeconomic characteristics, knowledge of the existence of HIV, HIV prevention, HIV stigma, intended pregnancy, and risk perceptions of engaging in unprotected sex. Results A large HIV knowledge gap between males and females was observed. Across the sexes, different types of knowledge are important in condom use. Low-risk perceptions of engaging in unprotected sex and not knowing that condoms prevent HIV infection appear to be the best predictors for risky sexual behavior among men. For females, stigma leads to lower condom use. Obviously, lack of knowledge on where condoms are available (9.4% and 29.1% of male and female respondents, respectively) reduced condom use in both males and females. Conclusion The results call for programmatic approaches to differentiate between males and females in the focus of HIV prevention campaigns. Moreover, the high predictive power of high-risk perceptions of engaging in unprotected sex (while correcting for other HIV knowledge indicators) calls for further exploration on how to influence these risk perceptions in HIV prevention programs.

Abstract
Objective Clinical and immunological data about HIV in older adults from low and middle income countries is scarce. We aimed to describe differences between younger and older adults with HIV starting antiretroviral therapy in two low–income African countries. Methods Setting: HIV clinics in Uganda and Zimbabwe.
Design: Secondary exploratory cross-sectional analysis of the DART randomized controlled trial.
Outcome Measures: Clinical and laboratory characteristics were compared between adults aged 18-49 years (younger) and ≥ 50 years (older), using two exploratory multivariable logistic regression models, one with HIV viral load (measured in a subset pre-ART) and one without. Results A total of 3316 eligible participants enrolled in DART were available for analysis; 219 (7%) were ≥ 50 years and 1160 (35%) were male. Across the two adjusted regression models, older adults had significantly higher systolic blood pressure, lower creatinine clearance and were consistently less likely to be females compared to younger adults with HIV. Paradoxically, the models separately suggested that older adults had statistically significant (but not clinically important) higher CD4+ cell counts and higher plasma HIV–1 viral copies at initiation. Crude associations between older age and higher baseline hemoglobin, body mass index, diastolic blood pressure and lower WHO clinical stage were not sustained in the adjusted analysis. Conclusions Our study found clinical and immunological differences between younger and older adults, in a cohort of Africans starting antiretroviral therapy. Further investigations should explore how these differences could be used to ensure equity in service delivery and affect outcomes of antiretroviral therapy.

Abstract
Objectives: Data from generalized epidemic settings have consistently found that patients on antiretroviral therapy (ART) reduce sexual risk behaviours, but how sexual behaviour changes in the general population in response to ART availability, including amongst HIV-uninfected and undiagnosed adults, has not been characterized in these settings. Design: General population open cohort. Methods: We report trends in sexual behaviour indicators for men aged 17–54 years and women aged 17–49 years in rural KwaZulu-Natal province, based on annual sexual behaviour surveys during ART scale-up from 2005 to 2011. Estimates are adjusted for survey nonparticipation and nonresponse to individual survey items using inverse probability weighting and multiple imputation. Trends are presented by HIV status, knowledge of status, age and marital status. Results: Reports of condom use at last sex with a regular partner increased by 2.6% points per year [95% confidence interval (CI) 1.5%, 3.7%] for men and 4.1% per year (3.0%, 5.3%) for women. Condom use at last sex with a casual partner was high and did not change significantly over the period for both sexes. There were statistically significant declines in the percentage reporting multiple partnerships in the last year and the point prevalence of concurrency. Trends within subgroups were generally consistent with overall estimates. Conclusion: We find no evidence of increased sexual risk-taking following ART availability and protective changes in some behaviours, suggesting that general trends in sexual behaviour are not counter-acting preventive effects of HIV treatment. Continued monitoring of population-level sexual behaviour indicators will be essential to interpret the success of combination-prevention programmes.

Abstract
This article presents baseline data from the SASA! (this is the Swahili for ‘now’) Study, a cluster randomized trial of a community-mobilization intervention to prevent violence against women and HIV/AIDS in Kampala, Uganda. Logistic regression was used to explore associations between intimate partner violence (IPV) and sexual risk behaviors, among 1,206 ever-partnered men and women (18-49 years). Twenty-seven percent of women reported past-year experience of physical and/or sexual IPV. Female experience and male perpetration of IPV were strongly associated with sexual risk behaviors. Findings confirm the importance of the SASA! intervention in this setting and endorse integrated strategies for IPV and HIV prevention.

Abstract
Context Cost-effective, scalable programs are urgently needed in countries deeply affected by HIV. Methods This parallel-group RCT was conducted in four secondary schools in Mbarara, Uganda. Participants were 12 years and older, reported past-year computer or Internet use, and provided informed caregiver permission and youth assent. The intervention, CyberSenga, was a five-hour online healthy sexuality program. Half of the intervention group was further randomized to receive a booster at four-months post-intervention. The control arm received ‘treatment as usual’ (i.e., school-delivered sexuality programming). The main outcome measures were: 1) condom use and 2) abstinence in the past three months at six-months' post-intervention. Secondary outcomes were: 1) condom use and 2) abstinence at three-month's post-intervention; and 6-month outcomes by booster exposure. Analyses were intention to treat. Results All 416 eligible youth were invited to participate, 88% (n = 366) of whom enrolled. Participants were randomized to the intervention (n = 183) or control (n = 183) arm; 91 intervention participants were further randomized to the booster. No statistically significant results were noted among the main outcomes. Among the secondary outcomes: At three-month follow-up, trends suggested that intervention participants (81%) were more likely to be abstinent than control participants (74%; p = 0.08), and this was particularly true among youth who were abstinent at baseline (88% vs. 77%; p = 0.02). At six-month follow-up, those in the booster group (80%) reported higher rates of abstinence than youth in the intervention, no booster (57%) and control (55%) groups (p = 0.15); they also reported lower rates of unprotected sex (5%) compared to youth in the intervention, no booster (24%) and control (21%) groups (p = 0.21) among youth sexually active at baseline. Conclusions The CyberSenga program may affect HIV preventive behavior among abstinent youth in the short term and, with the booster, may also promote HIV preventive behavior among sexually active youth in the longer term. Trial Registration NCT00906178.

Abstract
BACKGROUND Antiretroviral treatment restores the physical and immunological function for patients with HIV/AIDS and the return of sexual desire. The frequency and correlates of sexual activity among patients receiving ART have not been widely studied. There is concern that widespread availability of ART may result in sexual disinhibition including practice of high-risk sexual behavior. We determined the correlates of sexual activity and high-risk sexual behavior in an ART-treated population in rural and urban Uganda. METHODS We conducted a cross-sectional study among 329 ART-treated adult patients at two hospitals, one located in rural and another in urban western Uganda. We collected data on sexual activity, frequency of condom use, pregnancy, viral load (VL) and CD4. Patients were considered sexually active if they had had sexual intercourse in the last 6 months. Any unprotected sex was considered high-risk sex. A two-stage logistic regression was performed to determine factors associated with sexual activity and high-risk sex among those sexually active. RESULTS Overall, 222 (67%) patients were women, 138 (41.2%) had been on ART for at least one year, and 168 (51.4%) were sexually active of whom 127 (75.6%) used condoms at the last intercourse. Younger age (<=30 years) (Odds ratio; OR=2.3, 95% CI 1.2, 4.2), higher monthly income (OR=4.1, 95% CI 2.4, 7.4), and being married (OR=22.7, 95% CI 8.2, 62.9) were associated with being sexually active. Undetectable VL, CD4 count and treatment duration were not significantly associated with sexual activity. Among the sexually active, alcohol consumption (OR=3.3, 95% CI 1.2, 9.1) and unknown serostatus of partner (OR=5.8, 95% CI 1.5, 21.4) were significant predictors of high-risk sexual behavior. The frequency of unprotected sex at the last intercourse was 25.9% and 22.1% among the men and women respectively and was not significantly different (p value for chi square test =0.59). CONCLUSION Younger persons receiving ART are more likely to be sexually active. ART clients are more likely to engage in unprotected sex when sero-status of partner is unknown or report use of alcohol. Counseling on alcohol use and disclosure of sero-status may be useful in reducing high risk sexual behavior.

Abstract
The applicability of the IMB model in predicting condom use was tested among 390 sexually active secondary school students in Mbarara, Uganda. Adolescents across five secondary schools completed a self-report survey about their health and sexual experiences. Based upon results from structural equation modeling, the IMB model partially predicts condom use. Condom use was directly predicted by HIV prevention information and behavioral skills regarding having and using condoms. It was indirectly predicted (through behavioral skills regarding having and using condoms) by behavioral intentions regarding using condoms and talking to one's partner about safer sex. Aspects of one's first sexual experience (i.e., age at first sex, having discussed using condoms with first sex partner, willingness at first sex) were strongly influential in predicting current condom use; this was especially true for discussing condoms with one's first sex partner. Findings highlight the importance of providing clear and comprehensive condom use training in HIV prevention programs aimed at Ugandan adolescents. They also underscore the importance of targeting abstinent youth before they become sexually active to positively affect their HIV preventive behavior at their first sexual experience.

Abstract
This article explores three critical topics discussed in the recent debate over concurrency (overlapping sexual partnerships): measurement of the prevalence of concurrency, mathematical modelling of concurrency and HIV epidemic dynamics, and measuring the correlation between HIV and concurrency. The focus of the article is the concurrency hypothesis - the proposition that presumed high prevalence of concurrency explains sub-Saharan Africa's exceptionally high HIV prevalence. Recent surveys using improved questionnaire design show reported concurrency ranging from 0.8% to 7.6% in the region. Even after adjusting for plausible levels of reporting errors, appropriately parameterized sexual network models of HIV epidemics do not generate sustainable epidemic trajectories (avoid epidemic extinction) at levels of concurrency found in recent surveys in sub-Saharan Africa. Efforts to support the concurrency hypothesis with a statistical correlation between HIV incidence and concurrency prevalence are not yet successful. Two decades of efforts to find evidence in support of the concurrency hypothesis have failed to build a convincing case.

Abstract
Since self-reports of sensitive behaviors play an important role in HIV/AIDS research, the accuracy of these measures has often been examined. In this paper we (1) examine the effect of three survey interview methods on self-reported sexual behavior and perceptions of community sexual norms in Botswana, and (2) introduce an interview method to research on self-reported sexual behavior in sub-Saharan Africa. Comparing across these three survey methods (face-to-face, ballot box, and randomized response), we find that ballot box and randomized response surveys both provide higher reports of sensitive behaviors; the results for randomized response are particularly strong. Within these overall patterns, however, there is variation by question type; additionally the effect of interview method differs by sex. We also examine interviewer effects to gain insight into the effectiveness of these interview methods, and our results suggest that caution be used when interpreting the differences between survey methods.

Abstract
The General Population Cohort (GPC) was set up in 1989 to examine trends in HIV prevalence and incidence, and their determinants in rural south-western Uganda. Recently, the research questions have included the epidemiology and genetics of communicable and non-communicable diseases (NCDs) to address the limited data on the burden and risk factors for NCDs in sub-Saharan Africa. The cohort comprises all residents (52% aged ≥13years, men and women in equal proportions) within one-half of a rural sub-county, residing in scattered houses, and largely farmers of three major ethnic groups. Data collected through annual surveys include; mapping for spatial analysis and participant location; census for individual socio-demographic and household socioeconomic status assessment; and a medical survey for health, lifestyle and biophysical and blood measurements to ascertain disease outcomes and risk factors for selected participants. This cohort offers a rich platform to investigate the interplay between communicable diseases and NCDs. There is robust infrastructure for data management, sample processing and storage, and diverse expertise in epidemiology, social and basic sciences.

Abstract
Separated, divorced, and widowed individuals in Africa are at significantly increased risk for HIV infection. Using nationally representative data from 13 sub-Saharan African countries, this study confirms that finding and goes further by examining those who have experienced a marital dissolution and are now remarried. Results show that remarried individuals form a large portion of the population and have a higher-than-average HIV prevalence. HIV-positive remarried individuals are at risk of transmitting the infection to their spouse, because many of the couples are serodiscordant. The large number of high-risk remarried individuals is a source of vulnerability and further infection, and should be acknowledged and taken into account by prevention strategies that rarely address this population.

Abstract
Data from the Demographic and Health Surveys for Namibia, Swaziland, and Zambia and the AIDS Indicator Survey from Tanzania were used to examine the influence of marital status and number of partners on consistent condom use among men with casual sexual partnerships in four generalized HIV epidemic settings. We restrict the sample to the 26% (Zambia), 29% (Tanzania), 35% (Swaziland), and 42% (Namibia) of men, who, in the last 12 months before the survey, had any non-marital/non-cohabiting (i.e., casual) sexual partners. We use "condom always used with any partner in the last 12 months" as a dichotomous-dependent measure of consistent condom use. Analyses were stratified by country. Of men with casual partners, 41% (Zambia) to 70% (Namibia) used a condom every time with at least one partner. The majority of men were unmarried/non-cohabiting with one casual partner in the last year. In Swaziland and Zambia, multivariate results suggest that unmarried/non-cohabiting men with one casual partner had significantly lower odds than married/cohabiting men with casual partners to use condoms consistently (odds ratio [OR]=0.56, p=0.01 and OR=0.41, p<0.001, respectively.). In Namibia, unmarried/non-cohabiting men with two or more casual partners had significantly greater odds than married/cohabiting men with casual partners to use condoms consistently (OR=2.80, p<0.01). With some exceptions by country, higher education, religious group, wealth, having no children, knowing HIV results, having an STI, having one lifetime partner, and positive condom knowledge and beliefs also were significantly associated with using a condom every time with any partner. We conclude that consistent condom use remains an elusive goal even among men with casual sexual relationships. Condom use messages should be refined and targeted to men based on their number and types of relationships and combined with other messages to decrease concurrent relationships.

Abstract
With more than half of new infections occurring among youth, HIV/AIDS remains a major contributor to morbidity and mortality in Uganda. Semi-structured interviews were performed with 48 adolescents and 15 adult key informants in a rural Ugandan community to identify influences on adolescent sexual decision-making. Inductive data analytic methods revealed five thematic influences: (1) social pressure, (2) decline of the Senga (a familial figure who traditionally taught female adolescents about how to run a household), (3) cultural barriers to condom use, (4) knowledge of HIV transmission and modes of prevention, and (5) a moral injunction against sex before marriage. Influences were classified as HIV/AIDS risk and protective factors and organized to form an explanatory framework of adolescent sexual risk-taking. Risk factors pull youth toward risky behavior, while protective factors push them away. Predominance of risk over protective influences explains persistent sexual risk-taking by Ugandan youth. HIV prevention programs designed for Ugandan adolescents should take competing factors and sociocultural and economic influences into account.

Abstract
BACKGROUND Gender based violence, including violence by an intimate partner, is a major global human rights and public health problem, with important connections with HIV risk. Indeed, the elimination of sexual and gender based violence is a core pillar of HIV prevention for UNAIDS. Integrated strategies to address the gender norms, relations and inequities that underlie both violence against women and HIV/AIDS are needed. However there is limited evidence about the potential impact of different intervention models. This protocol describes the SASA! STUDY an evaluation of a community mobilisation intervention to prevent violence against women and reduce HIV/AIDS risk in Kampala, Uganda. METHODS/DESIGN The SASA! STUDY is a pair-matched cluster randomised controlled trial being conducted in eight communities in Kampala. It is designed to assess the community-level impact of the SASA! intervention on the following six primary outcomes: attitudes towards the acceptability of violence against women and the acceptability of a woman refusing sex (among male and female community members); past year experience of physical intimate partner violence and sexual intimate partner violence (among females); community responses to women experiencing violence (among women reporting past year physical/sexual partner violence); and past year concurrency of sexual partners (among males). 1583 women and men (aged 18-49 years) were surveyed in intervention and control communities prior to intervention implementation in 2007/8. A follow-up cross-sectional survey of community members will take place in 2012. The primary analysis will be an adjusted cluster-level intention to treat analysis, comparing outcomes in intervention and control communities at follow-up. Complementary monitoring and evaluation and qualitative research will be used to explore and describe the process of intervention implementation and the pathways through which change is achieved. DISCUSSION This is one of few cluster randomised trials globally to assess the impact of a gender-focused community mobilisation intervention. The multi-disciplinary research approach will enable us to address questions of intervention impact and mechanisms of action, as well as its feasibility, acceptability and transferability to other contexts. The results will be of importance to researchers, policy makers and those working on the front line to prevent violence against women and HIV. TRIAL REGISTRATION ClinicalTrials.Gov NCT00790959.

Abstract
Measurement of condom use is important to assess progress in increasing use. Since 2003, the Demographic and Health Surveys (DHS) and AIDS Indicator Surveys (AIS) have included new measures of self-reported condom use. We use data from Namibia, Swaziland, Tanzania, and Zambia to compare measures of condom use accounting for type of sexual partner. Condom use at last sex ranged from 20% in Tanzania to 57% in Namibia for men, and from 12% in Tanzania to 41% in Namibia for women. Reported condom use was lower in response to questions about condom use every time with last partner (from 13 to 47% for men and from 8 to 33% for women). Condom use was highest among people with two or more partners in the last year and lowest with marital partners. Overall, the prevalence of condom use was low, and there was wide variability across the various measures, countries, sexes, and types of partner. Promotion of condom use in all partnerships, but especially in non-marital relationships and among individuals with multiple partners, remains a critical strategy. New condom use questions in the DHS and AIS expand options for measuring and studying condom use.

Abstract
INTRODUCTION Sexual behavior changes are widely cited as contributing factors to sexually transmitted disease trends. We explore a rarely examined aspect of behavior trends in an open cohort--the relative impact of individuals' changing reported behavior versus new responses due to a changing respondent base. METHODS Respondents from an open cohort in Uganda annually answer questions on sexual behavior. We describe the impacts on behavior trends of: respondents' changing reported behavior, migration, mortality, changing eligibility for indicator inclusion, changing survey participation, and misreporting. We report contributions to trends on the following factors: condom use, ever had sex, age at first sex, and number of sexual partners and casual partners. RESULTS Main trend contributions varied by indicator. Condom use trends were influenced by individuals' changing responses and by increasing condom use among in-migrants and newly interviewed people. Sexual partners were driven by fewer partners among newly interviewed people, although increase of partners in 1999, 2004, and 2006 stemmed mainly from people changing answers. Thirty-nine percent of responses to age at first sex among 17- to 20-year-olds were inconsistent--different ages in different years. Early trends in the factor "ever had sex" among 15- to 19-year-olds were driven by people changing their answers--including ever to never, an impossible sequence. Comparing behavior in one year to mortality in the next, we found little evidence of higher mortality among higher risk takers. DISCUSSION In an open cohort, various factors contribute to sexual behavior trends. When reporting sexual behavior trends, researchers should acknowledge the contributing factors and attempt to separate the role of interindividual versus intraindividual changes.

Abstract
Unlike traditional approaches to sexuality and HIV education which can be constrained by the sensitive nature of the subject, Information Technology (IT) can be an innovative teaching tool that can be used to educate people about HIV. This is especially relevant to interventions targeting young people; the population group fond of using IT, and the same group that is more vulnerable to HIV/AIDS. Yet, there are significantly few empirical studies that rigorously evaluated computer-assisted school-based HIV/AIDS interventions in developing countries. The modest studies conducted in this area have largely been conducted in developed countries, leaving little known about the effectiveness of such interventions in low resource settings, which moreover host the majority of HIV/AIDS infections. This research addresses this gap by conducting a controlled pre-post intervention evaluation of the impacts of the World Starts With Me (WSWM), a computer-assisted HIV/AIDS intervention implemented in schools in Uganda. The research question was: did the WSWM intervention significantly influence students’ sexual behaviors, HIV/AIDS knowledge, attitudes and self-efficacy? To address this question, questionnaires were simultaneously administering to 146 students in an intervention group (the group receiving the WSWM intervention) and 146 students in a comparison group (the group who did not receive the WSWM intervention), before (February 2009) and after the intervention (December 2009). Findings indicate that the intervention significantly improved students’ HIV/AIDS knowledge, attitudes self-efficacy, sex abstinence and fidelity, but had no significant impact on condom use. The major reason for non-use of condoms was lack of knowledge about condom use which can be attributed to teachers’ failure and inabilities to demonstrate condom use in class. To address this challenge, intervention teachers should be continuously trained in skills-based and interactive sexuality education. This training will equip them with self-confidence and interactive teaching skills, including tactics for emphasizing building students’ skills through role plays and interactive assignments. In addition, the HIV interventions themselves should include interactive virtual condom use demonstrations that can be accessed by students themselves.

Background: Although Uganda had recorded declines in HIV infection rates around 1990’s, it is argued that HIV/AIDS risk sexual behaviour, especially among the youth, started increasing again from early 2000. School-based computer-assisted HIV interventions can provide interactive ways of improving the youth’s HIV knowledge, attitudes and skills. However, these interventions have long been reported to have limited success in improving the youth’s sexual behaviours, which is always the major aim of implementing such interventions. This could be because the commonly used health promotion theories employed by these interventions have limited application in HIV prevention. These theories tend to lack sufficient attention to contextual mediators that influence ones sexual behaviours. Moreover, literature increasingly expresses dissatisfaction with the dominant prevailing descriptive survey-type HIV/AIDS-related research. Objective and Methods: The objective of this research was to identify contextual mediators that influence the youth’s decision to adopt and maintain the HIV/AIDS preventive behaviour advocated by a computer-assisted intervention. To achieve this objective, this research employed qualitative method, which provided in-depth understanding of how different contexts interact to influence the effectiveness of HIV/AIDS interventions. The research question was: What contextual mediators are influencing the youth’s decision to adopt and maintain the HIV/AIDS preventive behaviour advocated by a computer-assisted intervention? To answer this research question, 20 youth who had previously completed the WSWM intervention when they were still in secondary schools were telephone interviewed between Sept.08 and Dec.08. The collected data was then analysed, based on grounded theory’s coding scheme. Results: Findings demonstrate that although often ignored by HIV interventionists and researchers, variety of contextual mediators influence individual uptake of HIV preventives. These include relationship characteristics, familial mediators, peer influence, gender-based social norms, economic factors and religious beliefs. Conclusion: To generate concomitant mutual efforts, rather than exclusively focusing on individual level mediators, there is an urgent need to shift to integrative approaches, which combine individual level change strategies with contextual level change approaches in the design and implementation of interventional strategies to fight against HIV/AIDS.

Abstract
Using nationally representative data from 13 sub-Saharan African countries, we reinforce and expand upon previous findings that men report using condoms more frequently than women do and that unmarried respondents report that they use condoms with casual partners more frequently than married individuals report using them with their spouses. Based on descriptive, bivariate, and multivariate analyses, we also demonstrate to a degree not previously shown in the current literature that married men from most countries report using condoms with extramarital partners about as frequently as unmarried men report using them with casual partners. Married women from most of the countries included in the study reported using condoms with extramarital partners less frequently than unmarried women reported using them with casual partners. This result is especially troubling because marriage usually ensures regular sexual intercourse, thereby providing more opportunities for a person to pass HIV infection from an extramarital partner to his or her spouse. These findings about high-risk behaviors can be used to better target future HIV-transmission-prevention efforts.

Abstract
Background Local HIV epidemiology data are critical in determining the suitability of a
population for HIV vaccine efficacy trials. The objective of this study was
to estimate the prevalence and incidence of, and determine risk factors for
HIV transmission in a rural community-based HIV vaccine preparedness cohort
in Masaka, Uganda. Methods Between February and July 2004, we conducted a house-to-house HIV
sero-prevalence survey among consenting individuals aged 18–60 years.
Participants were interviewed, counseled and asked to provide blood for HIV
testing. We then enrolled the HIV uninfected participants in a 2-year HIV
sero-incidence study. Medical evaluations, HIV counseling and testing, and
sample collection for laboratory analysis were done quarterly. Sexual risk
behaviour data was collected every 6 months. Results The HIV point prevalence was 11.2%, and was higher among women than
men (12.9% vs. 8.6%, P = 0.007). Risk
factors associated with prevalent HIV infection for men were age <25
years (aOR = 0.05, 95% CI 0.01–0.35) and
reported genital ulcer disease in the past year
(aOR = 2.17, 95% CI 1.23–3.83). Among
women, being unmarried (aOR = 2.59, 95% CI
1.75–3.83) and reported genital ulcer disease in the past year
(aOR = 2.40, 95% CI 1.64–3.51) were
associated with prevalent HIV infection. Twenty-one seroconversions were
recorded over 2025.8 person-years, an annual HIV incidence of 1.04%
(95% CI: 0.68–1.59). The only significant risk factor for
incident HIV infection was being unmarried (aRR = 3.44,
95% CI 1.43–8.28). Cohort retention after 2 years was
87%. Conclusions We found a high prevalence but low incidence of HIV in this cohort. HIV
vaccine efficacy trials in this population may not be feasible due to the
large sample sizes that would be required. HIV vaccine preparatory efforts
in this setting should include identification of higher risk
populations.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) prevalence in Uganda fell during the 1990s and has risen since 2000. The changing trends since 2000 may be due to changing risky sexual behaviour, but other factors may also contribute. We explore the possible impact that two factors may have on cohort trends: natural epidemic dynamics and local migration. We simultaneously fit a mathematical model to the contrasting prevalence trends by age/gender in a southwest Ugandan cohort, which has never been done before. METHODS We fit a model to HIV trends, by age groups and gender, assuming: (i) neither migration nor intentional behaviour change, (ii) migration changes, (iii) intentional behaviour changes and (iv) both change. The model fits were assessed through sum of squares goodness of fits. We also explored the impact of the natural course of the epidemic on average partner acquisition rates, under the condition of no intentional behaviour change over time. RESULTS Without allowing intentional change in partner acquisition rates, an excellent fit was achievable to prevalence trends by gender. However, all of the contrasting trends by age/gender could not be replicated simultaneously. Adding intentional behaviour change improved the fit to some groups, but not all. Adding both intentional behaviour change and migration further improved the fit. CONCLUSIONS While some of the increasing HIV prevalence in Uganda since 2000 may be due to increased risky behaviour, some of the observed epidemiologic trends would likely occur without any intentional change in behaviour. Average population-level behaviour can change due to preferential mortality among higher risk takers, without individuals changing their behaviour.

Abstract
BACKGROUND The residual risk of human immunodeficiency virus (HIV) transmission from blood products in the Abidjan National Blood Transfusion Center was estimated to be 1 in 5780 blood donations over the period 2002 through 2004. We aimed at describing risk behaviors in blood donors who seroconverted for HIV in Abidjan to improve the pre-blood donation selection. STUDY DESIGN AND METHODS We investigated the behavioral profile of HIV seroconverters assessed before their HIV diagnosis, during the blood donation selection at the blood bank of Abidjan, and compared it to the profile documented after this HIV diagnosis, at enrollment in the PRIMO-CI cohort. Since 1997, enrollment in this cohort is offered to every blood donor whose delay since HIV seroconversion was 36 months or less. RESULTS Among the 418 blood donors who seroconverted for HIV between 1997 and 2005, 241 were enrolled in the cohort. Median age was 28 years and 63% were men. The median time between the last HIV-negative test and the first positive test was 7 months. Since the last blood donation, 29% of donors reported unprotected sexual intercourse with multiple casual sexual partners, 55% unprotected sexual intercourse with one casual sexual partner, and 36% sharing of nail clippers. During the pre-blood donation questionnaire, 69% of HIV seroconverters had reported unprotected sexual intercourse since the last blood donation (vs. 89% reported after donation), and 7% had had multiple casual sexual partners (vs. 32%). CONCLUSION Volunteer blood donors who seroconverted for HIV in Abidjan reported a high proportion of unprotected sexual intercourse with casual sexual partners.

Abstract
OBJECTIVES To assess inconsistencies in reported age at first sex (AFS) and age at first marriage (AFM) in three African cohorts, and consider their implications for interpreting trends in sexual and marital debut. METHODS Data were analysed from population-based cohort studies in Zimbabwe, Uganda and South Africa with 3, 10 and 4 behavioural survey rounds, respectively. Three rounds over a similar time frame were selected from each site for comparative purposes. The consistency of AFS and AFM reports was assessed for each site by comparing responses made by participants in multiple surveys. Respondents were defined as unreliable if less than half of all their age-at-event reports were the same. Kaplan-Meier functions were used to describe the cumulative proportion (1) having had sex and (2) married by age, stratified by sex, birth cohort and site, to compare the influence of reporting inconsistencies on these estimates. RESULTS Among participants attending all three comparable rounds, the percentage with unreliable AFS reports ranged from 30% among South African women to 56% among Zimbabwean men, with similar patterns observed for AFM. Inclusion of unreliable reports had little effect on estimates of median age-at-event in all sites. There was some evidence from the 1960-9 birth cohort that women in Uganda and both sexes in South Africa reported later AFS as they aged. CONCLUSION Although reporting quality is unlikely to affect comparisons of AFS and AFM between settings, care should be taken not to overinterpret small changes in reported age-at-event over time within each site.
