BackgroundCommunity Health Workers (CHWs) have a crucial role in improving health in their communities and their role is being expanded in many parts of the world. However, the effectiveness of CHWs is limited by poor training and the education of CHWs has received little scientific attention.MethodsOur study was carried out in two districts of KwaZulu-Natal, South Africa. We developed and piloted an inexpensive (two day) training intervention covering national government priorities: HIV/AIDS, sexually transmitted disease and Tuberculosis; and Women’s Sexual and Reproductive Health and Rights. Sixty-four CHWs consented to participate in the main study which measured knowledge gains using a modified Solomon design of four different testing schedules to distinguish between the effects of the intervention, testing and any interaction between intervention and testing. We also measured confidence, satisfaction and costs.ResultsFollowing the training intervention, improvements in knowledge scores were seen across topics and across districts. These changes in knowledge were statistically significant (p<0.001) and of large magnitude (over 45 percentage points or four standard deviations). However, the CHWs assigned to the test-test-train schedule in one district showed high gains in knowledge prior to receiving the training. All CHWs reported high levels of satisfaction with the training and marked improvements in their confidence in advising clients. The training cost around US$48 per CHW per day and has the potential to be cost-effective if the large gains in knowledge are translated into improved field-based performance and thus health outcomes.ConclusionTraining CHWs can result in large improvements in knowledge with a short intervention. However, improvements seen in other studies could be due to test ‘reactivity’. Further work is needed to measure the generalisability of our results, retention of knowledge and the extent to which improved knowledge is translated into improved practice.

Background: The global mining industry is an important partner in advancing the 2030 Agenda for Sustainable Development. In 2018, Anglo American plc published their Sustainable Mining Plan, containing a goal for improving health and wellbeing aligned with the Sustainable Development Goal 3 (SDG3) targets. Having formed an independent multidisciplinary research consortium, we designed and implemented a mixed-methods approach to attain a deeper understanding of SDG3 priorities within the local context of communities hosting Anglo American mining operations located in Latin America. Methods: In 2019, within the host communities of three mining operations in Chile, three in Brazil, and one in Peru, we conducted a qualitative study which included stakeholder workshops and key informant interviews. We also quantitatively appraised existing health data.Findings emerging from the qualitative and quantitative assessments were compared to identify health and wellbeing priority areas for action relevant to each community. Results: Across the three countries, 120 people took part in workshops and 35 in interviews. In these workshops and interviews, non-communicable diseases (SDG3.4), harmful alcohol consumption (SDG3.5), and pollution, particularly air pollution (SDG3.9), were consistently identified as areas for priority action. There were similarities in the reporting of individual, interpersonal, community, societal, and structural factors underlying these priority areas across the different communities. The availability of quantitative data was generally good at the state level, becoming increasing sparse as we focused on smaller geographies. The priorities identified in the quantitative assessments generally aligned with those highlighted in the qualitative data. Conclusions: We highlight the importance of engaging with local populations to understand and address health needs. To address the priorities identified, intervention packages tailored to the specific needs of host communities, that tackle associated upstream societal level factors, are required. To facilitate this, appropriate monitoring systems and epidemiological investigations should be implemented to better understand the local context and quantify health issues. In the host communities, it is essential for the mining sector to be a key health partner in promoting integrated programmes that contribute to achieving the priority objectives and targets aligned with the SDG3 agenda.

Migration is a complex process that is fundamental in understanding the complexity of societies across the world. In South Africa, there are high levels of migration associated with HIV and AIDS, and the process is intrinsically linked with issues associated with population health. Research conducted in KwaZulu-Natal Province, and in the wider country, has reported on a circular migratory flow of women to and from the province. However, this paper presents findings suggesting that the gendered migration occurring in this area is actually an intergenerational process of chain migration that involves women of different generations moving to South Africa from households in other southern African countries. Younger women are initially motivated to move by various push and pull factors, such as economic or environmental instability. Despite enthusiasm to move and motivation to succeed in South Africa, their experiences of migration to South Africa are mostly characterised by negativity. Often exposed to unsafe conditions coupled with a lack of opportunities for meaningful work, many are left vulnerable to HIV contraction. Older women then migrate to follow their daughters in response to requests for support, forming the second phase of this process of intergenerational chain migration. As a result of this process, which is strongly influenced by HIV, there are emerging communities of younger women who require access to services for HIV, and older women who are in need of primary care services associated with ageing while they are providing assistance to their kin and new host communities.
