RESUMO
BACKGROUND: The feasibility of reducing the population-level incidence of human immunodeficiency virus (HIV) infection by increasing community coverage of antiretroviral therapy (ART) and male circumcision is unknown. METHODS: We conducted a pair-matched, community-randomized trial in 30 rural or periurban communities in Botswana from 2013 to 2018. Participants in 15 villages in the intervention group received HIV testing and counseling, linkage to care, ART (started at a higher CD4 count than in standard care), and increased access to male circumcision services. The standard-care group also consisted of 15 villages. Universal ART became available in both groups in mid-2016. We enrolled a random sample of participants from approximately 20% of households in each community and measured the incidence of HIV infection through testing performed approximately once per year. The prespecified primary analysis was a permutation test of HIV incidence ratios. Pair-stratified Cox models were used to calculate 95% confidence intervals. RESULTS: Of 12,610 enrollees (81% of eligible household members), 29% were HIV-positive. Of the 8974 HIV-negative persons (4487 per group), 95% were retested for HIV infection over a median of 29 months. A total of 57 participants in the intervention group and 90 participants in the standard-care group acquired HIV infection (annualized HIV incidence, 0.59% and 0.92%, respectively). The unadjusted HIV incidence ratio in the intervention group as compared with the standard-care group was 0.69 (P = 0.09) by permutation test (95% confidence interval [CI], 0.46 to 0.90 by pair-stratified Cox model). An end-of-trial survey in six communities (three per group) showed a significantly greater increase in the percentage of HIV-positive participants with an HIV-1 RNA level of 400 copies per milliliter or less in the intervention group (18 percentage points, from 70% to 88%) than in the standard-care group (8 percentage points, from 75% to 83%) (relative risk, 1.12; 95% CI, 1.09 to 1.16). The percentage of men who underwent circumcision increased by 10 percentage points in the intervention group and 2 percentage points in the standard-care group (relative risk, 1.26; 95% CI, 1.17 to 1.35). CONCLUSIONS: Expanded HIV testing, linkage to care, and ART coverage were associated with increased population viral suppression.

Despite the rising burden of noncommunicable diseases, access to quality decentralized noncommunicable disease services remain limited in many low- and middle-income countries. Here we describe the strategies we employed to drive the process from adaptation to national endorsement and implementation of the 2016 Botswana primary healthcare guidelines for adults. The strategies included detailed multilevel assessment with broad stakeholder inputs and in-depth analysis of local data; leveraging academic partnerships; facilitating development of supporting policy instruments; and embedding noncommunicable disease guidelines within broader primary health-care guidelines in keeping with the health ministry strategic direction. At facility level, strategies included developing a multimethod training programme for health-care providers, leveraging on the experience of provision of human immunodeficiency virus care and engaging health-care implementers early in the process. Through the strategies employed, the country's first national primary health-care guidelines were endorsed in 2016 and a phased three-year implementation started in August 2017. In addition, provision of primary health-care delivery of noncommunicable disease services was included in the country's 11th national development plan (2017-2023). During the guideline development process, we learnt that strong interdisciplinary skills in communication, organization, coalition building and systems thinking, and technical grasp of best-practices in low- and middle-income countries were important. Furthermore, misaligned agendas of stakeholders, exaggerated by a siloed approach to guideline development, underestimation of the importance of having policy instruments in place and coordination of the processes initially being led outside the health ministry caused delays. Our experience is relevant to other countries interested in developing and implementing guidelines for evidence-based noncommunicable disease services.
Malgré la charge de morbidité croissante des maladies non transmissibles, l'accès à des services décentralisés de qualité pour lutter contre ces maladies reste limité dans de nombreux pays à revenu faible ou intermédiaire. Dans cet article, nous décrivons les stratégies qui ont été employées pour mener les étapes d'adaptation, de validation et de mise en Åuvre à l'échelle nationale des Lignes directrices 2016 du Botswana sur les soins de santé primaires pour l'adulte. Ces stratégies ont inclus: une évaluation multiniveau détaillée avec une large implication des parties prenantes et une analyse approfondie des données locales; le recours à des partenariats universitaires; la promotion de l'élaboration d'instruments politiques propices; l'intégration de lignes directrices portant spécifiquement sur les maladies non transmissibles dans les lignes directrices générales sur les soins primaires, en écho à l'orientation stratégique du ministère de la Santé. Au niveau des établissements de santé, les stratégies ont inclus: la création d'un programme de formation multiméthode à destination des prestataires de soins; l'exploitation de l'expérience acquise dans la prise en charge du virus de l'immunodéficience humaine et l'implication des prestataires de soins très tôt dans le processus. Grâce aux stratégies employées, les premières lignes directrices nationales sur les soins de santé primaires ont été validées en 2016, et une étape de mise en Åuvre graduelle, sur trois ans, a commencé en août 2017. De plus, la prestation de soins de santé primaires contre les maladies non transmissibles a été incluse dans le 11e plan national de développement du pays (2017-2023). Pendant la phase d'élaboration des lignes directrices, nous avons constaté toute l'importance, dans les pays à revenu faible et intermédiaire, de pouvoir compter sur de solides compétences interdisciplinaires en matière de communication, d'organisation, de création de coalitions et de réflexion systémique et d'obtenir une bonne compréhension technique des meilleures pratiques. Nous avons par ailleurs observé des retards provoqués par des problèmes d'incompatibilité d'agendas entre les différentes parties prenantes, exagérés par des approches cloisonnées lors de la phase d'élaboration des lignes directrices, par la sous-estimation de l'importance d'avoir des outils politiques déjà en place et par des difficultés de coordination des processus initialement pilotés hors du ministère de la Santé. Notre expérience peut être utile pour d'autres pays qui souhaiteraient élaborer et mettre en Åuvre des lignes directrices pour des services de soins contre les maladies non transmissibles fondés sur des données probantes.
A pesar de la creciente carga de las enfermedades no transmisibles, el acceso a servicios de calidad descentralizados para estas enfermedades sigue siendo limitado en muchos países de bajos y medianos ingresos. A continuación, describimos las estrategias que empleamos para impulsar el proceso desde la adaptación a la aprobación nacional y la implementación de las directrices de atención primaria de la salud para adultos de Botswana de 2016. Las estrategias incluían una evaluación detallada a varios niveles con amplias aportaciones de las partes interesadas y un análisis a fondo de los datos locales; el aprovechamiento de las asociaciones académicas; la facilidad para elaborar instrumentos normativos de apoyo; la incorporación de directrices sobre las enfermedades no transmisibles en las directrices más amplias sobre la atención primaria de la salud, de conformidad con la dirección estratégica del Ministerio de Salud. A nivel de los centros de salud, las estrategias incluían la elaboración de un programa de capacitación multimétodo para los proveedores de servicios de salud, el aprovechamiento de la experiencia en la prestación de servicios de atención del virus de la inmunodeficiencia humana y la participación de los encargados de la ejecución de los servicios de salud en las primeras etapas del proceso. Gracias a las estrategias empleadas, en 2016 se aprobaron las primeras directrices nacionales de atención primaria de la salud del país y en agosto de 2017 se inició una aplicación por etapas de tres años. Además, la prestación de servicios de atención primaria de la salud para las enfermedades no transmisibles se incluyó en el 11º plan nacional de desarrollo del país (2017-2023). Durante el proceso de desarrollo de las directrices, aprendimos que eran importantes las buenas habilidades interdisciplinarias en comunicación, organización, formación de coaliciones y pensamiento sistémico, así como la comprensión técnica de las mejores prácticas en los países de ingresos bajos y medios. Por otra parte, las agendas desalineadas de las partes interesadas, exageradas por el enfoque aislado del desarrollo de las directrices, la subestimación de la importancia de contar con instrumentos de política y la coordinación de los procesos que inicialmente se llevaban a cabo fuera del ministerio de salud causaron retrasos. Nuestra experiencia es relevante para otros países interesados en desarrollar e implementar directrices para servicios de enfermedades no transmisibles basados en la evidencia.

OBJECTIVE: To evaluate the variation in all-cause attrition [mortality and loss to follow-up (LTFU)] among HIV-infected individuals in Botswana by health district during the rapid and massive scale-up of the National Treatment Program. METHODS: Analysis of routinely collected longitudinal data from 226 030 patients who received ART through the Botswana National HIV/AIDS Treatment Program across all 24 health districts from 2002 to 2013. A time-to-event analysis was used to measure crude mortality and loss to follow-up rates (LTFU). A marginal structural model was used to evaluate mortality and LTFU rates by district over time, adjusted for individual-level risk factors (e.g. age, gender, baseline CD4, year of treatment initiation and antiretroviral regimen). RESULTS: Mortality rates in the districts ranged from the lowest 1.0 (95% CI 0.9-1.1) in Selibe-Phikwe, to the highest 5.0 (95% CI 4.0-6.1), in Mabutsane. There was a wide range of overall LTFU across districts, including rates as low as 4.6 (95% CI 4.4-4.9) losses per 100 person-years in Ngamiland, and 5.9 (95% CI 5.6-6.2) losses per 100 person-years in South East district, to rates as high as 25.4 (95% CI 23.08-27.89) losses per 100 person-years in Mabutsane and 46.3 (95% CI 43.48-49.23) losses per 100 person-years in Okavango. Even when known risk factors for mortality and LTFU were adjusted for, district was a significant predictor of both mortality and LTFU rates. CONCLUSION: We found statistically significant variation in attrition (mortality and LTFU) and data quality among districts. These findings suggest that district-level contextual factors affect retention in treatment. Further research needs to investigate factors that can potentially cause this variation.
RESUMO
What is already known on this topic? Human papillomavirus (HPV) infection is common and aggressive in persons infected with human immunodeficiency virus (HIV). With an HIV prevalence of 28% among females aged 1549, cervical cancer is the leading cause of cancer death among women in Botswana. Before 2013, HPV vaccine had not been used in the public sector in Botswana.What is added by this report? Efforts to expand services for cervical cancer through the Pink Ribbon Red Ribbon initiative focused on HPV-related disease in Botswana. A demonstration project for HPV vaccination was developed by the Ministry of Health for school girls aged ≥9 years in primary schools in one community. A total of 1,967 (79%) of 2,488 eligible girls received 3 doses of vaccine in the immunization effort that was centered in schools.What are the implications for public health practice? Preventing HPV infection in girls is an important component of a national comprehensive cervical cancer control program. HPV vaccination programming is challenging, and demonstration projects can prepare countries for national introduction. The success of the initial HPV vaccination effort in Botswana led to an expanded project in 2014, with implementation of nationwide rollout of the HPV vaccine in 2015. It might be beneficial for future HPV vaccination campaigns to include strategies to reach out-of-school girls.

Equitable access to antiretroviral therapy (ART) for men and women with human immunodeficiency virus (HIV) infection is a principle endorsed by most countries and funding bodies, including the U.S. President's Emergency Plan for AIDS (acquired immunodeficiency syndrome) Relief (PEPFAR) (1). To evaluate gender equity in ART access among adults (defined for this report as persons aged ≥15 years), 765,087 adult ART patient medical records from 12 countries in five geographic regions* were analyzed to estimate the ratio of women to men among new ART enrollees for each calendar year during 2002-2013. This annual ratio was compared with estimates from the Joint United Nations Programme on HIV/AIDS (UNAIDS)() of the ratio of HIV-infected adult women to men in the general population. In all 10 African countries and Haiti, the most recent estimates of the ratio of adult women to men among new ART enrollees significantly exceeded the UNAIDS estimates for the female-to-male ratio among HIV-infected adults by 23%-83%. In six African countries and Haiti, the ratio of women to men among new adult ART enrollees increased more sharply over time than the estimated UNAIDS female-to-male ratio among adults with HIV in the general population. Increased ART coverage among men is needed to decrease their morbidity and mortality and to reduce HIV incidence among their sexual partners. Reaching more men with HIV testing and linkage-to-care services and adoption of test-and-treat ART eligibility guidelines (i.e., regular testing of adults, and offering treatment to all infected persons with ART, regardless of CD4 cell test results) could reduce gender inequity in ART coverage.

The 2011 prevalence of human immunodeficiency virus (HIV) among pregnant women in Botswana was 30.4%. High coverage rates of HIV testing and antiretroviral prophylaxis have reduced the rate of mother-to-child transmission of HIV in Botswana from as high as 40% with no prophylaxis to <4% in 2011. In June 2005, the national Early Infant Diagnosis (EID) Program began testing HIV-exposed infants (i.e., those born to HIV-infected mothers) for HIV using polymerase chain reaction (PCR) at 6 weeks postpartum. During 2005-2012, follow-up of all HIV-infected infants diagnosed in all 13 postnatal care facilities in Francistown, Botswana, was conducted to ascertain patient outcomes. A total of 202 infants were diagnosed with HIV. As of September 2013, 82 (41%) children were alive and on antiretroviral therapy (ART), 79 (39%) had died, and 41 (20%) were either lost to follow-up, had transferred, or their mothers declined ART. Despite success in preventing mother-to-child transmission in Botswana, results of the EID program highlight the need for early diagnosis of HIV-infected infants, prompt initiation of ART, and retention in care.

BACKGROUND: Increasing HIV treatment coverage is crucial to reducing population-level HIV incidence. METHODS: The Botswana Combination Prevention Project (BCPP) was a community randomized trial examining the impact of multiple prevention interventions on population-level HIV incidence and was conducted from October 2013 through June 2017. Home and mobile campaigns offered HIV testing to all individuals ≥ age 16. All identified HIV-positive persons who were not on antiretroviral therapy (ART) were referred to treatment and tracked to determine linkage to care, ART status, retention in treatment, and viral suppression. RESULTS: Of an estimated total of 14,270 people living with HIV (PLHIV) residing in the 15 intervention communities, BCPP identified 13,328 HIV-positive persons (93%). At study start, 10,703 (80%) of estimated PLHIV knew their status; 2,625 (20%) learned their status during BCPP, a 25% increase with the greatest increases occurring among men (37%) and youth (77%). At study start, 9,258 (65%) of estimated PLHIV were on ART. An additional 3,001 persons started ART through the study. By study end, 12,259 had initiated and were retained on ART, increasing coverage to 93%. A greater increase in ART coverage was achieved among men (40%) compared to women (29%). Of the 11,954 persons who had viral load (VL) test results, 11,687 (98%) were virally suppressed (HIV-1 RNA ≤400 copies/mL). Overall, 82% had documented VL suppression by study end. CONCLUSIONS: Knowledge of HIV-positive status and ART coverage increased towards 95-95 targets with universal testing, linkage interventions, and ART. The increases in HIV testing and ART use among men and youth were essential to reaching these targets. CLINICAL TRIAL NUMBER: NCT01965470.

BACKGROUND: In settings with high HIV prevalence and treatment coverage, such as Botswana, it is unknown whether uptake of HIV prevention and treatment interventions can be increased further. We sought to determine whether a community-based intervention to identify and rapidly treat people living with HIV, and support male circumcision could increase population levels of HIV diagnosis, treatment, viral suppression, and male circumcision in Botswana. METHODS: The Ya Tsie Botswana Combination Prevention Project study was a pair-matched cluster-randomised trial done in 30 communities across Botswana done from Oct 30, 2013, to June 30, 2018. 15 communities were randomly assigned to receive HIV prevention and treatment interventions, including enhanced HIV testing, earlier antiretroviral therapy (ART), and strengthened male circumcision services, and 15 received standard of care. The first primary endpoint of HIV incidence has already been reported. In this Article, we report findings for the second primary endpoint of population uptake of HIV prevention services, as measured by proportion of people known to be HIV-positive or tested HIV-negative in the preceding 12 months; proportion of people living with HIV diagnosed and on ART; proportion of people living with HIV on ART with viral suppression; and proportion of HIV-negative men circumcised. A longitudinal cohort of residents aged 16-64 years from a random, approximately 20% sample of households across the 15 communities was enrolled to assess baseline uptake of study outcomes; we also administered an end-of-study survey to all residents not previously enrolled in the longitudinal cohort to provide study end coverage estimates. Differences in intervention uptake over time by randomisation group were tested via paired Student's t test. The study has been completed and is registered with ClinicalTrials.gov (NCT01965470). FINDINGS: In the six communities participating in the end-of-study survey, 2625 residents (n=1304 from standard-of-care communities, n=1321 from intervention communities) were enrolled into the 20% longitudinal cohort at baseline from Oct 30, 2013, to Nov 24, 2015. In the same communities, 10â791 (86%) of 12â489 eligible enumerated residents not previously enrolled in the longitudinal cohort participated in the end-of-study survey from March 30, 2017, to Feb 25, 2018 (5896 in intervention and 4895 in standard-of-care communities). At study end, in intervention communities, 1228 people living with HIV (91% of 1353) were on ART; 1166 people living with HIV (88% of 1321 with available viral load) were virally suppressed, and 673 HIV-negative men (40% of 1673) were circumcised in intervention communities. After accounting for baseline differences, at study end the proportion of people living with HIV who were diagnosed was significantly higher in intervention communities (absolute increase of 9% to 93%) compared with standard-of-care communities (absolute increase of 2% to 88%; prevalence ratio [PR] 1·08 [95% CI 1·02-1·14], p=0·032). Population levels of ART, viral suppression, and male circumcision increased from baseline in both groups, with greater increases in intervention communities (ART PR 1·12 [95% CI 1·07-1·17], p=0·018; viral suppression 1·13 [1·09-1·17], p=0·017; male circumcision 1·26 [1·17-1·35], p=0·029). INTERPRETATION: It is possible to achieve very high population levels of HIV testing and treatment in a high-prevalence setting. Maintaining these coverage levels over the next decade could substantially reduce HIV transmission and potentially eliminate the epidemic in these areas. FUNDING: US President's Emergency Plan for AIDS Relief through the Centers for Disease Control and Prevention.

BACKGROUND: HIV-1 RNA load is the best biological predictor of HIV transmission and treatment response. The rate of virologic suppression among key subpopulations can guide HIV prevention programs. METHODS: The Botswana Combination Prevention Project performed a population-based household survey among adults in 30 communities in Botswana. Data collected included knowledge of HIV-positive status, antiretroviral therapy (ART) coverage, and virologic suppression (HIV-1 RNA ≤400 copies per milliliter). Individuals aged 16-29 years were considered young adults. RESULTS: Among 552 young people living with HIV enrolled with RNA load data and ART status available, 51% (n = 279) had undetectable HIV-1 RNA, including 54% of young women and 32% of young men [sex prevalence ratio (PR): 0.53; 95% confidence interval (CI): 0.43 to 0.80; P < 0.001]. Compared with older adults (30-64 years old), young HIV-infected adults were significantly less likely to have undetectable HIV-1 RNA (PR: 0.65; 95% CI: 0.59 to 0.70; P < 0.0001), including both men (PR: 0.43; 95% CI: 0.34 to 0.56; P < 0.0001) and women (PR: 0.67; 95% CI: 0.62 to 0.74; P < 0.0001). Among a subset of people living with HIV receiving ART, young adults also were less likely to have undetectable HIV-1 RNA load than older adults (PR: 0.93; 95% CI: 0.90 to 0.95; P = <0.0001). Analysis of the care continuum revealed that inferior HIV diagnosis and suboptimal linkage to care are the primary reasons for low virologic suppression among young adults. CONCLUSIONS: Young adults in Botswana are significantly less likely to have undetectable HIV-1 RNA load compared with older adults. In the era of broad scale-up of ART, interventions able to diagnose young adults living with HIV and link them to effective therapy are urgently needed.

OBJECTIVES: To determine the incidence and risk factors of mortality for all HIV-infected patients receiving antiretroviral treatment at public and private healthcare facilities in the Botswana National HIV/AIDS Treatment Programme. DESIGN: We studied routinely collected data from 226â030 patients enrolled in the Botswana National HIV/AIDS Treatment Programme from 2002 to 2013. METHODS: A person-years (P-Y) approach was used to analyse all-cause mortality and follow-up rates for all HIV-infected individuals with documented antiretroviral therapy initiation dates. Marginal structural modelling was utilized to determine the effect of treatment on survival for those with documented drug regimens. Sensitivity analyses were performed to assess the robustness of our results. RESULTS: Median follow-up time was 37 months (interquartile range 11-75). Mortality was highest during the first 3 months after treatment initiation at 11.79 (95% confidence interval 11.49-12.11) deaths per 100 P-Y, but dropped to 1.01 (95% confidence interval 0.98-1.04) deaths per 100 P-Y after the first year of treatment. Twelve-month mortality declined from 7 to 2% of initiates during 2002-2012. Tenofovir was associated with lower mortality than stavudine and zidovudine. CONCLUSION: The observed mortality rates have been declining over time; however, mortality in the first year, particularly first 3 months of antiretroviral treatment, remains a distinct problem. This analysis showed lower mortality with regimens containing tenofovir compared with zidovudine and stavudine. CD4 cell count less than 100 cells/µl, older age and being male were associated with higher odds of mortality.

OBJECTIVE: To measure the association between the number of doctors, nurses and hospital beds per 10,000 people and individual HIV-infected patient outcomes in Botswana. DESIGN: Analysis of routinely collected longitudinal data from 97,627 patients who received ART through the Botswana National HIV/AIDS Treatment Program across all 24 health districts from 2002 to 2013. Doctors, nurses, and hospital bed density data at district-level were collected from various sources. METHODS: A multilevel, longitudinal analysis method was used to analyze the data at both patient- and district-level simultaneously to measure the impact of the health system input at district-level on probability of death or loss-to-follow-up (LTFU) at the individual level. A marginal structural model was used to account for LTFU over time. RESULTS: Increasing doctor density from one doctor to two doctors per 10,000 population decreased the predicted probability of death for each patient by 27%. Nurse density changes from 20 nurses to 25 nurses decreased the predicted probability of death by 28%. Nine percent decrease was noted in predicted mortality of an individual in the Masa program for every five hospital bed density increase. CONCLUSION: Considerable variation was observed in doctors, nurses, and hospital bed density across health districts. Predictive margins of mortality and LTFU were inversely correlated with doctor, nurse and hospital bed density. The doctor density had much greater impact than nurse or bed density on mortality or LTFU of individual patients. While long-term investment in training more healthcare professionals should be made, redistribution of available doctors and nurses can be a feasible solution in the short term.

BACKGROUND: HIV programmes face challenges achieving high rates of HIV testing and treatment needed to optimise health and to reduce transmission. We used data from the Botswana Combination Prevention Project study survey to assess Botswana's progress toward achieving UNAIDS targets for 2020: 90% of all people living with HIV knowing their status, 90% of these receiving sustained antiretroviral therapy (ART), and 90% of those having virological suppression (90-90-90). METHODS: A population-based sample of individuals was recruited and interviewed in 30 rural and periurban communities from Oct 30, 2013, to Nov 24, 2015, as part of a large, ongoing community-randomised trial designed to assess the effect of a combination prevention package on HIV incidence. A random sample of about 20% of households in each community was selected. Consenting household residents aged 16-64 years who were Botswana citizens or spouses of citizens responded to a questionnaire and had blood drawn for HIV testing in the absence of documentation of positive HIV status. Viral load testing was done in all HIV-infected participants, irrespective of treatment status. We used modified Poisson generalised estimating equations to obtain prevalence ratios, corresponding Huber robust SEs, and 95% Wald CIs to examine associations between individual sociodemographic factors and a binary outcome indicating achievement of the three individual and combined overall 90-90-90 targets. The study is registered at ClinicalTrials.gov, number NCT01965470. FINDINGS: 81% of enumerated eligible household members took part in the survey (10% refused and 9% were absent). Among 12â610 participants surveyed, 3596 (29%) were infected with HIV, and 2995 (83·3%, 95% CI 81·4-85·2) of these individuals already knew their HIV status. Among those who knew their HIV status, 2617 (87·4%, 95% CI 85·8-89·0) were receiving ART (95% of those eligible by national guidelines, and 73% of all infected people). Of the 2609 individuals receiving ART with a viral load measurement, 2517 (96·5%, 95% CI 96·0-97·0) had viral load of 400 copies per mL or less. Overall, 70·2% (95% CI 67·5-73·0) of HIV-infected people had virological suppression, close to the UNAIDS target of 73%. INTERPRETATION: UNAIDS 90-90-90 targets are achievable even in resource-constrained settings with high HIV burden. FUNDING: US President's Emergency Plan for AIDS Relief through the Centers for Disease Control and Prevention.

To identify factors associated with HIV in Botswana, a standardized questionnaire was administered to 135 tuberculosis patients with known HIV status. HIV-positive patients were more likely than HIV-negative patients to: be female (45% vs 26% (adjusted prevalence odds ratio (aPOR)=3.8, 95% confidence interval (CI)=1.1-12.7)); be 26-35 years old (50% vs 19% (aPOR=2.7, CI=0.7-10.7)); be unmarried (91% vs 71% (aPOR=13.3, CI=2.5-72.7)); have higher income (24% vs 10% (aPOR=8.2, CI=1.6-42.9)); report separation from spouse/partner for work (63% vs 52% (aPOR=1.8, CI=0.5-6.2)); have 2 sex partners other than their regular partner (82% vs 67% (aPOR=1.8, CI=0.5-7.5)); and state that they or their partner drank alcohol before sex (77% vs 55% (aPOR=6.8, CI=1.9-24.1)). Only 22% of respondents used condoms during all of their past 10 sexual encounters. These data provide information for HIV prevention strategies.
