The Coronavirus Disease 2019 (COVID-19) pandemic has had wide-reaching direct and indirect impacts on population health. In low- middle-income countries, these can halt progress toward reducing maternal child mortality. This study estimates changes in health services utilization during the associated consequences for maternal, neonatal,
In 2020, the World Health Assembly endorsed Immunization Agenda 2030 (IA2030), 2021-2030 global strategy that envisions a world where everyone, everywhere, at every age, fully benefits from vaccines. This report reviews trends in Organization and UNICEF immunization coverage estimates global, regional, national levels through 2022 documents progress toward improving with respect to IA2030 strategy, which aims reduce number of children who have not received first dose...
In 2020, the World Health Assembly endorsed Immunization Agenda 2030 (IA2030), a 10-year strategy to reduce vaccine-preventable disease (VPD)-associated morbidity and mortality. IA2030 goals include improving equitable vaccination coverage, halving number of unimmunized (zero-dose) children, increasing introduction new underutilized vaccines. The COVID-19 pandemic disrupted health systems worldwide, hindering years childhood achievements putting global public at risk. This report presents...
The Eastern Cape province of South Africa has one the highest burdens HIV in world. Emergency Departments (EDs) can serve as optimal clinical sites for identification new infections and entry into care. We sought to determine current burden disease among ED patients Cape. conducted a prospective cross-sectional observational study EDs three Hospitals from June 2017 July 2018. All adult, non-critical presenting were systematically approached offered Point-Of-Care (POC) test accordance with...
Background Vaccine hesitancy remains a critical barrier in mitigating the effects of ongoing COVID-19 pandemic. The willingness health care workers (HCWs) to be vaccinated, and, turn, recommend vaccine for their patient population is an important strategy. This study aims understand uptake vaccines and reasoning among facility-based LMICs. Methods We conducted nationally representative phone-based rapid-cycle surveys across facilities six LMICs better hesitancy. gathered data on facility...
Transmission of HIV in South Africa continues to be high due a large proportion individuals living with undiagnosed HIV. Uptake testing is influenced by multitude factors including the patient's knowledge and beliefs about HIV.This study sought quantify impact attitudes on acceptance an emergency department co-administering validated survey patients who were subsequently offered testing.During period 223 interviewed testing. Individuals reporting more negative overall (p = 0.006), higher...
Background Preeclampsia increases women's risks for maternal morbidity and future cardiovascular disease. The aim of this study was to identify opportunities prevention by examining the association between cardiometabolic risk factors preeclampsia across 2 pregnancies among women in a high-risk US birth cohort. Methods Results Our sample included 618 Boston Birth Cohort with index subsequent pregnancy data collected using standard protocols. We conducted log-binomial univariate regression...
Background: Age-disparate relationships are associated with increased HIV prevalence. We determined whether the frequency of age-disparate in never married women changed over time and they prevalence Rakai, Uganda. Methods: A total 10,061 women, aged 15–49 years, Rakai Community Cohort Study provided information on age their male sexual partners from 1997 to 2013. Logistic regression was used assess trends (≥5 years) between partners. Log-binomial estimate adjusted ratios (adjPR)...
Happiness and self-rated physical health are included in national surveys to assess perceptions subjective well-being among individuals. Studies have reported that happiness impacts health; however, little is known about the association between African American men (AAM). The objective of this study examine relationship. Participants were 1,263 AAM aged 18+ years from National Survey Life who rated their health. Interviews conducted 2001 2003. Self-rated was defined as how individuals own...
Monitoring service quality for family planning programmes in low- and middle-income countries (LMICs) has been challenging due to data availability. Self-reported from Demographic Health Surveys (DHS) can provide additional information on beyond simple contact.
The aim of the study was to describe HIV care continuum in emergency department (ED) patients Eastern Cape region South Africa. This is a cross-sectional, identity-unlinked serosurvey, whereby discarded/excess samples from all who had blood drawn during period for routine and sufficient serum remaining were tested HIV, hepatitis B virus, C virus infection; viral load (VL); presence antiretroviral (ARV) drugs. We also estimated cross-sectional incidence using Limiting-Antigen Avidity assay...
Background: During and after the SARS-CoV-2 (COVID-19) pandemic, many countries experienced declines in immunization that have not fully recovered to pre-pandemic levels. This study uses routine health facility data estimate variability between within post-pandemic service recovery for BCG, DPT1, DPT3. Methods: After adjusting reporting completeness outliers, interrupted time series regression was used expected volume each subnational unit, using an interruption point of March 2020. We...
Countries with health workforce shortages are increasingly turning to multipurpose community workers (CHWs) extend integrated services the community-level. However, there may be tradeoffs number of tasks a CHW can effectively perform before quality and/or productivity decline. This qualitative study was conducted within an existing program in Iringa, Tanzania where HIV-focused CHWs working as volunteers received additional training on maternal, newborn, and child (MNCH) promotion, thereby...
Rapid HIV tests are critical to surveillance and universal testing treatment programs. We assessed longitudinal patterns in indeterminate rapid test results an African population-based cohort. Prospective antibody results, defined by two parallel tests, among participants aged 15-49 years from three survey rounds of the Rakai Community Cohort Study, Uganda, 2013 2018, were assessed. An result was as any weak positive or when one negative other positive. A total 31,405 contributed 54,459...
Background Indeterminate HIV test results are common, but little is known about the evolution of indeterminate serology and its sociodemographic behavioral correlates. We assessed future serological outcomes for individuals with associated factors in Rakai, Uganda. Methods 115,944 results, defined by two enzyme immunoassay (EIAs), among 39,440 aged 15–49 years Rakai Community Cohort Study were assessed. as contradictory EIAs. Modified Poisson regression models generalized estimating...
