新型冠状病毒大流行暴露了不平等的裂痕，因为应对机制有限的弱势社会群体的粮食不安全和营养不足问题加剧。鉴于其影响是通过多层面途径感受到的，一些研究人员强调，需要在具体情况下分析这一流行病。采用随机和固定效应回归模型，本研究分析了从冈比亚农村和城市的103个曼丁卡家庭收集的纵向调查数据。该研究采用方便和滚雪球抽样，每月通过移动的电话访谈收集详细的收入、食品消费、支出、采购、迁移、健康和应对机制数据，共获得676个观察结果。粮食不安全表现在质量而不是数量上，而且在不同的食物种类和家庭中分布不均。饮食结果和采购策略与地理位置、卫生条件改善、家庭规模、月收入变化、新冠肺炎政策严格程度和新冠肺炎病例有关，但这些关联因食物类别而异。斯台普斯是最常食用的食物组，深绿色蔬菜最少。农村社区更有可能吃更多健康的小米，但不太可能消费乳制品或根和块茎。获得自己生产的富含维生素A的食物也很重要，但提高收入和市场是蛋白质和富含血红素铁的食物的关键。更严格的新冠肺炎政策与饮食多样性呈负相关，沿着对市场囤积的恐惧，与依赖一系列消费和生产应对机制呈正相关。在较大的家庭和水和卫生条件得到改善的家庭中，复原力较高。新型冠状病毒病例的数量与高蛋白质食物的消费量增加和对自产富含铁的食物的依赖程度增加有关。很少有家庭得到政府的援助，得到援助的家庭已经有了其他收入来源。我们的研究结果表明，粮食不安全的性质可能在大流行期间随着时间的推移而演变。他们还重申，不仅市场准入和就业机会的重要性，而且通过在特定营养食物组来源之间转换，吸收负担能力冲击和保持食物选择的能力因家庭和地点而异。
The Covid pandemic has exposed fissures of inequality through heightened food insecurity and nutritional deficiency for vulnerable social cohorts with limited coping mechanisms. Given the multi-dimensional pathways through which its effects have been felt, several researchers have highlighted the need to analyse the pandemic in specific contexts. Using random and fixed effect regression models, this study analyzed longitudinal survey data collected from 103 Mandinka households in rural and urban Gambia. The study employed convenience and snowball sampling and involved the monthly collection of detailed income, food consumption, expenditure, sourcing, migration, health, and coping mechanism data through mobile phone interviews which yielded 676 observations. Food insecurity was manifest in terms of quality, not quantity, and spread unevenly across food types and households. Dietary outcomes and sourcing strategies were associated with location, improved sanitation, household size, changes in monthly income, Covid policy stringency, and Covid cases but these associations varied by food group. Staples were the most frequently consumed food group, and dark green vegetables were the least. Rural communities were more likely to eat more healthy millets but much less likely to consume dairy products or roots and tubers. Access to own production was also important for Vitamin A-rich foods but higher incomes and markets were key for protein and heme-iron-rich foods. Tighter Covid policy stringency was negatively associated with dietary diversity and, along with fear of market hoarding, was positively associated with reliance on a range of consumption and production coping mechanisms. Resilience was higher in larger households and those with improved water and sanitation. The number of Covid cases was associated with higher consumption of protein-rich foods and greater reliance on own produced iron-rich foods. Very few households received Government aid and those that did already had access to other income sources. Our findings suggest that the nature of food insecurity may have evolved over time during the pandemic. They also reiterate not only the importance of access to markets and employment but also that the capacity to absorb affordability shocks and maintain food choices through switching between sources for specific nutritious food groups varied by household and location.
