In 2016, an estimated 1.5 million females aged 15-24 years were living with human immunodeficiency virus (HIV) infection in Eastern and Southern Africa, where the prevalence of HIV among adolescent girls young women (3.4%) is more than double that for males same age range (1.6%) (1). Progress was assessed toward Joint United Nations Programme on HIV/AIDS (UNAIDS) 2020 targets sub-Saharan Africa (90% those aware their status, 90% HIV-infected persons status antiretroviral treatment [ART],...
This study uses observational data collected as part of Zambia's male circumcision program to measure sexual behavior in the postsurgical healing period and model its influence on HIV transmission for men their partners.From August October 2010, 248 about undergo were recruited participate. Interviews conducted at baseline 6 weeks after circumcision, recommended abstinence complete wound healing. Logistic Poisson regression models used assess risk factors early resumption sex. A...
Background We examined the epidemiology and transmission potential of HIV population viral load (VL) in 12 sub-Saharan African countries. Methods analyzed data from Population-based Impact Assessments (PHIAs), large national household-based surveys conducted between 2015 2019 Cameroon, Cote d’Ivoire, Eswatini, Kenya, Lesotho, Malawi, Namibia, Rwanda, Tanzania, Uganda, Zambia, Zimbabwe. Blood-based biomarkers included serology, recency infection, VL. estimated number people living with...
The Zambian government has implemented a public health response to control the HIV epidemic in country. Zambia conducted population-based impact assessment (ZAMPHIA) survey 2021 assess status of guide its programs.
This article draws on biomarker data from Demographic and Health Surveys (2003–2007) in 10 sub-Saharan African countries to examine differences fertility preferences contraceptive behaviors by HIV status for women men, taking into account whether or not they probably know their status. The objective is determine if there are common patterns the associations between these variables across several countries. Women's men's relatively similar probable knowledge of that However, two consistent...
CONTEXT: Sub-Saharan Africa is burdened by high rates of unintended pregnancy and HIV.Yet little known about the relationship between these two health risks in region.Understanding associations HIV status decision making may benefit strategies to reduce pregnancy.METHODS: In 2009-2010, household-based surveys 1,256 women Nigeria 1,280 Zambia collected information on social demographic characteristics, pregnancy, contraceptive use, abortion self-reported status.Multivariate models were used...
Understanding the epidemiological HIV context is critical in building effective setting-specific preventive strategies. We examined prevalence patterns selected communities of men and women aged 15–59 years Zambia. Population-based surveys 1995 (n = 3158), 1999 3731) 2003 4751) were conducted using probability proportional to size stratified random-cluster sampling. Multivariate logistic regression trend analyses by residence, sex age group. Absence, <30% <15% all rounds, was most important...
Scaling up services to achieve HIV targets will require that countries optimize the use of available funding. Robust unit cost estimates are essential for better resources, and information on heterogeneity in delivering across facilities - both within is critical identifying addressing inefficiencies. There limited prevention sub-Saharan Africa determinants this variation even more scarce. The "Optimizing Response Prevention: Efficiency Africa" (ORPHEA) study aims add empirical body...
Although stigma towards HIV-positive women for both continuing and terminating a pregnancy has been documented, to date few studies have examined relative one outcome versus the other. This study seeks describe community attitudes each of two possible elective outcomes an woman's - induced abortion or birth determine which garners more document characteristics members associated with stigmatising outcome. Data come from community-based interviews reproductive-aged men women, 2401 in Zambia...
The premise for using antenatal care (ANC) clinic data estimating HIV prevalence in the general population is finding from community studies sub-Saharan Africa that total pregnant women attending ANC clinics closely approximate levels of both and men aged 15-49 years. In this study, validity national level estimates years made survey was assessed.In 2001-2002, a 15-59 conducted Zambia. same period, sentinel surveillance among carried out.The age-group (rural: 11.5%; 95% CI, 11.2-11.8; urban:...
In this study, we described facility-level voluntary medical male circumcision (VMMC) unit cost, examined cost variation across facilities, and investigated key facility characteristics associated with variation. We used data from 107 facilities in Kenya, Rwanda, South Africa, Zambia covering 2011 or 2012. micro-costing to estimate economic costs the service provider's perspective. Average annual per client were estimated 2013 United States dollars (US$). Econometric analysis was explore...
Summary Objective To examine the contribution of human immunodeficiency virus (HIV) to adult death rates between 1995/1996 and 1998/1999 in some urban rural populations Zambia. Method A cohort 2592 out 3013 adults aged 15–49 years enrolled a baseline survey areas Chelston Township (HIV prevalence 26.2%) Kapiri Mposhi district 15.6%) were followed up 1998/1999. Person observation (PYO) calculated for those known have been alive, dead migrated surveys. Fixed covariates Cox proportional hazard...
The increasing availability of antiretroviral therapy (ART) and drug regimens to prevent mother-to-child transmission (PMTCT) has probably changed the context childbearing for people living with HIV. Using data from 2009-2010 community-based surveys in Nigeria Zambia, this study explores whether women's knowledge about ART PMTCT influences relationship between HIV status fertility preferences contraceptive behaviour. findings show that women are more likely want children limit Zambia...
Background: Nationally representative, household-based, health-related surveys are an invaluable source of health information, but face implementation challenges. In sub-Saharan Africa, these challenges exacerbated when include the collection biological specimens. this study, we describe potential identified during field practice leading up to 2020 Zambia Population-based HIV Impact Assessment (ZAMPHIA) survey, and explore role two crises on community mistrust of, apprehension to,...
Background As male circumcision (MC) programs are scaled-up for HIV prevention, it is critically important to measure the prevalence of risk behaviours post-MC. Of particular concern potential increased HIV-1 transmission and acquisition as a result premature resumption sexual activity during 6-week healing period post-MC, when clients instructed abstain from sex. The presentation will review sex highlight factors early model impact such behaviour at population level. Methods study was...
