Impact of COVID‑19 on food security and diet quality in Chilanga District, Zambia

Introduction Food security and nutrition have been severely impacted during the COVID-19 pandemic, particularly in low- and middle-income countries (LMICs). We aimed to quantify the impacts of the pandemic on food security and diet diversity within Chilanga District in Zambia and identify target areas for high-impact social protection and safety net programs. Methods We conducted a cross-sectional study in Chilanga district immediately after the Omicron variant surge in February 2022. Diet quality and food security were assessed based on a household diet questionnaire and a Minimum Dietary Diversity-Women (MDD-W) score was calculated. A paired t-test was used to determine whether there was a statistically significant change in the MDD-W score and McNemar test was used to investigate the change in food security between the pre- and peri-COVID-19 period. Results Compared to the pre-COVID-19 period, there were increases in food prices across the board in the peri- COVID-19 period and decreased consumption of key food categories including legumes, dairy and vitamin A rich foods. Despite high rates of food insecurity, only 6.6% of surveyed households received any cash or in-kind assistance from a government agency, non-profit, or other organization in the post-COVID-19 period. Conclusion The COVID-19 pandemic had significant impacts on food security and dietary diversity in Chilanga district. This is particularly relevant in the low-income communities that we surveyed, which had pre-existing challenges with food security. Additional resources must be invested in Chilanga District and similarly affected areas to address this gap in access to food and promote national equity

Undernutrition in older children and adolescents in peri-urban Zambia

Background: Adolescents make up roughly a quarter of the population in Zambia; however, most nutrition-related programming is targeted at the underfive population. Understanding the scale of undernutrition in older children and adolescents is fundamental to alleviating food insecurity and addressing undernutrition across all age groups. Methods: A cross-sectional survey was performed in four low-income, peri-urban compounds in Chilanga District which included anthropometric measurements of children between ages 6 months-19 years and a household-level diet diversity and food security questionnaire. Wasting was used for children under 5 and thinness for children 5–19 years. Descriptive analysis and multivariate logistic regression were conducted to quantify the prevalence and distribution of malnutrition and understand the impact of food security. Results: We surveyed 393 households and 1,004 children between the ages of 6 months and 19 years. Children aged 6–9 years had the highest prevalence of severe thinness (5.2%) and adolescents (10–19 years) had the highest rates of moderate thinness (6.5%). Across all age groups, more than 75% of children were in households that worried about running out of food in the previous month. 24.9% of adolescents and 28.4% of older children were in households were more likely to go a whole day without eating compared to 16.9% of children under 5. Conclusion: Our survey indicated that malnutrition in adolescents and older children living in Chilanga district was comparable to those under 5. Interventions to address undernutrition must be targeted at older children and adolescents in order to ameliorate this burden

Learner Milestones to Guide Decolonial Global Health Education

The current movement to ‘decolonize’ global health aims to both dismantle colonial frameworks that perpetuate inequity and racism, as well as to rebuild and uplift structures and systems that celebrate indigeneity. However, it is critical to recognize that teaching decoloniality within global health education is more than just the acknowledgement that there are key paradigms missing from current global health education. It is imperative to have a methodology to hold ourselves and our learners accountable to progress in practices and ideals that promote equity-based praxis. In this paper, we propose the creation of a tool to assess learner levels and their progression over time in both recognizing the impacts of colonialism and acting to transform their own global health praxis towards equity and decoloniality. We developed a model to illustrate an increasing scope and impact of decolonial and global health equity praxis. We hypothesize through this model that the way in which learners engage with power dynamics and structural advocacy at each level is essential to describing learner stages. Based on extensive literature review, existing curricular frameworks, global partner discussion(s), feedback on our pilot curriculum, and adaptation of philosophical theory, these learner milestones were conceptualized. We discuss the inherent challenges in assessment of the complex mix of knowledge, attitude and skills described in these milestones with the understanding that any such assessment would always be formative, as we all continue learning how to do better. We hope these milestones can be utilized to promote critical transformational change in the field of global health. This requires deep self-reflection and examination of existing structures of oppression followed by intentional reparative actions to embody decoloniality in our praxis and advocacy and reimagine global health based on equity and local leadership

Primary series COVID-19 vaccine effectiveness among healthcare workers in Albania, February–December 2021

Background: Healthcare workers have experienced high rates of morbidity and mortality from coronavirus disease 2019 (COVID-19). Methods: A prospective cohort study was conducted in three Albanian hospitals between 19 February and 14 December 2021. All participants underwent polymerase chain reaction (PCR) and serological testing at enrolment, regular serology throughout, and PCR testing when symptomatic. Vaccine effectiveness (VE) against COVID-19 and against all severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections (symptomatic or asymptomatic) was estimated. VE was estimated using a Cox regression model, with vaccination status as a time-varying variable. Findings: In total, 1504 HCWs were enrolled in this study; 70% had evidence of prior SARS-CoV-2 infection. VE was 65.1% [95% confidence interval (CI) 37.7–80.5] against COVID-19, 58.2% (95% CI 15.7–79.3) among participants without prior SARS-CoV-2 infection, and 73.6% (95% CI 24.3–90.8) among participants with prior SARS-CoV-2 infection. For BNT162b2 alone, VE was 69.5% (95% CI 44.5–83.2). During the period when the Delta variant was predominant, VE was 67.1% (95% CI 38.3–82.5). VE against SARS-CoV-2 infection for the full study period was 36.9% (95% CI 15.8–52.7). Interpretation: This study found moderate primary series VE against COVID-19 among healthcare workers in Albania. These results support the continued promotion of COVID-19 vaccination in Albania, and highlight the benefits of vaccination in populations with high levels of prior infection

Learning to walk the walk: Incorporating praxis for decolonization in global health education

Colonial history has deeply influenced the structures that govern global health. Though many curricula promote equity, few focus on developing competency in understanding and dismantling colonialism, and the structural barriers to global health equity. To dismantle colonial structures and create equitable collaborations, learners must be able to recognise how colonialism permeates global health practice. We propose a praxis cycle in education that asks learners to actively engage with these concepts. The praxis cycle includes: Theory: Learners explore the principles of decoloniality to understand how attitudes and practices are shaped by biased social structures influenced by colonialism. Reflection: Learners reflect on their work in LMIC settings through a lens of decoloniality and positionality. Action: Learners work in LMIC settings where they apply and actively engage with these concepts and insights. During implementation of this curriculum, we encountered several challenges including the cognitive dissonance of the learner to changing mental models of global health practice, existing systemic barriers to changing one’s practice and the development of accountability mechanisms for learners in this type of curriculum. Intentionally incorporating a praxis cycle helps learners recognise their role in disrupting the structural forces that promote inequities, and actively dismantle the forces upholding systemic oppression
