    We examine population mobility around a newly-developed large-scale copper mine in Zambia and analyse how socioeconomic and health indicators differed amongst migrants, resettled households, and non-mobile local (e.g. non-migrant/-resettled) populations. Two cross-sectional household surveys in 2015 and 2019 collected quan-titative data on health, socioeconomic indicators, and resettlement and migration status. A wealth index for the pooled sample (N =990 households) was computed using a simplified list of household assets adapted from the Zambia Demographic and Health Survey. Logistic regression models were conducted to assess associations with health outcomes. In-migrants were younger than non-mobile locals (mean age of household head 33.9 vs. 37.7 years), more highly educated (34.3% of household heads completed secondary school vs. 7.3%), had higher employment (43.8% vs. 15.8%), and higher mean wealth (3.6 vs. 3.0). The odds of having a child <5 years diagnosed with malaria (OR: 0.53, 95% CI: 0.40, 0.71) or classified as stunted (OR: 0.66, 95% CI: 0.50, 0.87) were significantly lower for migrants during the construction phase, even after adjusting for family wealth score. Migrant and resettled households had greater wealth and assets even after adjusting for age, education, and employment, suggesting spatial mobility is associated with improved socioeconomic status and disease prevention

    Changes in household wealth in communities living in proximity to a large-scale copper mine in Zambia

    Large-scale mining can alter the living conditions of surrounding communities in positive and negative ways. A health impact assessment conducted in the context of a newly developed large-scale copper mine in rural Zambia gave us the opportunity to measure changes in health determinants over time. We conducted periodic household surveys at baseline in 2011, during the construction phase in 2015 and during the operational phase in 2019. Data collected included economic indicators that were based on the standardized list of household assets used in the Zambia Demographic and Health Survey, which we subsequently converted into a wealth score using principal component analysis. We compared mean wealth scores in six communities directly impacted by the mine with comparison communities, as well as the rest of the North-Western province of Zambia. A difference-indifferences linear regression model was used to compare changes over time. Mean wealth of the communities near the mine was significantly lower at baseline than that of the North-Western province (? 0.54 points; pvalue< 0.001) in 2011, but surpassed the regional average in 2019 (+1.07 points; p-value <0.001). Mean wealth increased more rapidly in communities directly impacted by mine than in the comparison communities (+0.30 points, p-value <0.001). These results suggest a positive impact on living conditions in communities living near this copper mine. Our findings underscore the potential of the mining sector to contribute to economic development in Zambia

    Schistosomiasis and soil-transmitted helminth infections in schoolchildren in north-eastern Democratic Republic of the Congo

    Get PDF
    BACKGROUND: There is a paucity of epidemiological data pertaining to schistosomiasis and soil-transmitted helminth (STH) infections in the Democratic Republic of the Congo (DRC). METHODS: A cross-sectional survey was carried out in the north-eastern part of DRC enrolling 400 schoolchildren aged 9-14 years. Stool and urine samples were subjected to standard diagnostic methods and examined under a microscope for helminth eggs. RESULTS: Four out of five children were infected with at least one helminth species. Schistosoma mansoni was the predominant species (57.8%). Urine examinations were all negative for S. haematobium. CONCLUSIONS: S. mansoni and STH infections are highly endemic in the surveyed part of the DRC, calling for interventions in school-aged children

    Virtual care pathways for people living with HIV:A mixed‐methods systematic review

    Get PDF
    Background: The COVID-19 pandemic prompted an unprecedented surge in virtual services, necessitating a rapid shift to digital healthcare approaches. This review focuses on evaluating the evidence of virtual care (VC) in delivering HIV care, considering the complex nature of HIV and the need for tailored-approaches, especially for marginalized populations.Methods: A mixed-methods systematic review was performed with searches on five databases, covering studies from January 1946 to May 2022. Inclusion criteria involved two-way virtual consultations between healthcare workers and people living with HIV (PLHIV), with detailed descriptions and outcomes. Qualitative and quantitative studies were included, and the risk of bias was assessed using the Newcastle–Ottawa score and Stenfors' framework.Results: Among 4143 identified records, 26 studies met the criteria, with various models of care described. The majority of studies were observational, and videoconferencing was the primary mode of virtual consultation employed. Quantitative analysis revealed PLHIV generally accept VC, with high attendance rates (87%). Mean acceptability and satisfaction rates were 80% and 85%, respectively, while 87% achieved HIV viral suppression. The setting and models of VC implementation varied, with some introduced in response to COVID-19 while others were as part of trials.Conclusions: VC for PLHIV is deemed an acceptable and effective approach and is associated with good virological outcomes. Data on other health outcomes is lacking. The review underscores the importance of diverse models of care, patient choice and comprehensive training initiatives for both staff and patients. Establishing a ‘gold standard’ for VC models is crucial for ensuring appropriate and effective reviews of PLHIV in virtual settings.</div

    Current Global Health Impact Assessment Practice

    Health impact assessment (HIA) practice has expanded across the world, since it was established more than two decades ago. This paper presents a snapshot of current global HIA practice based on the findings of an online questionnaire survey. HIA practitioners from all world regions were invited to participate. A total of 122 HIA practitioners from 29 countries completed the survey, following a broad international outreach effort. The large variety in the types of HIAs conducted, and the application of HIA in various fields reported by respondents, demonstrates that HIA practice has evolved over the past two decades. Although differences in the use of HIA were reported across world regions, an overall increasing trend in global HIA practice can be observed. In order to sustain this upward trend, efforts are needed to address the main barriers in the utilisation of HIA. The establishment of new national and international HIA teaching and training offerings seems to be an obvious strategy to pursue along with the strengthening of policies and legal frameworks that specify the circumstances, under which HIA is required, and to what extent
