There are about 292 clinical studies being (or have been) conducted in Zambia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a pilot pulmonary TB screening program done in three antenatal care clinics in Lusaka, Zambia to determine the prevalence of culture-confirmed pulmonary tuberculosis and to determine the sensitivity and specificity of symptom-based TB screening.
This is a study to evaluate Xpert MTB/RIF as the first-line TB diagnostic test in HIV-infected adults and pediatric patients as a means to obtain faster, more accurate TB diagnosis.
This study will examine an enhanced protocol to systematically screen a cohort of 400 new HIV clinic enrollees for prevalence and 1-year incidence of tuberculosis (TB).
The Centre for Infectious Disease Research in Zambia (CIDRZ) and researchers from the University of North Carolina at Chapel Hill (UNC) have partnered to pilot an peer-referral incentive program to increase voluntary medical male circumcision (VMMC) uptake in Zambia. The program allows each man coming for circumcision to refer up to 5 uncircumcised men in their social network for VMMC services and receive a monetary reward for each successful referral. The peer-referral program offers several advantages over traditional demand-creation approaches that rely on employing mobilizers or community health workers (CHWs). The amount of the monetary incentive will be analogous to the amount of incentive that CHWs might receive for comparable effort, making the program suitable for large-scale expansion. The effect of the peer-referral program on uptake of VMMC services will be evaluated using a rigorous methodology proposed by UNC researchers.
In many low-income countries, the use of ultrasound by medical officers and non-physician health care staff (e.g., midwives) for antenatal identification of high risk pregnancies is a new intervention requiring authoritative investigation. The primary hypothesis to be assessed in this study is that antenatal ultrasound screenings performed by medical officers and non-physician health care staff will significantly reduce a composite outcome consisting of maternal mortality and maternal near miss, stillbirth and neonatal mortality in low-resource settings. Underpinning this hypothesis are two assumptions. The first assumption is that antenatal detection of complicated pregnancies will lead to appropriate referral at the right time for complicated pregnancies to comprehensive emergency obstetric and neonatal care (EmONC) facilities. The second assumption is that ultrasound's introduction will increase antenatal attendance leading to greater rates of institutional delivery. To assess these underlying assumptions beyond the composite end point, this study will investigate the health system impact of compact ultrasound. Secondary outcomes include antenatal attendance rates, institutional delivery rates at basic EmONC facilities, referral rates to comprehensive EmONC facilities, cesarean section rates (both planned and emergent) and an assessment of medical officers and non-physician health care provider ultrasound competence and training quality.
Validate a promising community survey methodology for evaluating the Prevention of Mother to Child Transmission (PMTCT) program effectiveness against a "gold standard" cohort design and to identify individual- and facility-level characteristics associated with HIV-free survival among HIV-exposed infants.
BHOMA Interventions The purpose of this study is to assess the impact of the BHOMA intervention on health in 3 rural districts of Zambia.
There is a large body of evidence from adult populations suggesting cognition in adults is affected by hydration status. The few studies conducted in the global North in populations of schoolchildren indicate that drinking water has an impact on pupil performance on basic cognitive tasks. No studies assessing the impact of dehydration and cognition in schoolchildren have been published in the global South, where access to water is the poorest and dehydration prevalence is likely higher. Our group previously carried out research on this topic in Mali, and will build upon findings from that work with this trial. This study will examine the effect of drinking supplementary water during the school day on hydration status and on cognitive test scores in schoolchildren in Zambia. The investigators hypothesize that providing supplemental water will result in a decrease in prevalence of dehydration in the study group and will result in an improved performance on cognitive test scores. Data will be collected from up to four purposively-selected schools in the region of Zambia where this study is taking place, from up to a total of 400 children. At each school pupils in grades 3-6 will be eligible for recruitment, dependent upon their understanding of research instructions. Research staff will explain the study to pupils at the school and individually request informed oral assent for participation. A waiver of parental consent for pupil interviews will be secured from the Ministry of Education. At each school, school directors will be asked to sign in loco parentis ("in the place of parent") on behalf of the pupil participants. Children that assent to participate in the study will be randomly allocated to the intervention or control group. In the intervention group, study participants will receive supplementary water in the morning. In the control group, study participants will receive supplementary water in the afternoon. Testing procedures in both groups is identical and will include a five-minute interview, two cognitive testing sessions of 45 minutes each, and collection of two urine samples during the day. None of these activities collect personal data or identifiers, and the urine sample will not be stored. All data collection will occur at the school and will be conducted by trained local enumerators. There are no risks to participation other than a small amount of class time missed by pupils, and great efforts will be made to minimize time outside of class.
The purpose of the study is to determine whether daily consumption of beta-carotene biofortified maize will increase breast milk retinol concentration in lactating Zambian women.
PopART is a community randomized trial that is investigating whether a community-wide combination HIV prevention package including annual home-based HIV testing, active referral and the offer of immediate ART for those testing HIV-positive, along with the promotion of proven HIV prevention methods (such as voluntary medical male circumcision, prevention of mother to child transmission and condom use), will help to prevent transmission and substantially reduce new HIV infections. The study is being conducted in 21 communities in Zambia and South Africa (randomized into 3 arms, each with 7 communities) with a total population of approximately 1.2 million individuals.
