This study set out to investigate the risk of household food insecurity in Nigeria during the novel COVID-19 pandemic using a harmonised dataset of Nigeria's prepandemic face-to-face survey and two waves of the COVID-19 National Longitudinal Phone Survey (NLPS).
Nigeria.
A representative sample of 1674 households is used in the analysis.
A longitudinal study.
Our longitudinal study reveals a significant increase in the prevalence of food insecurity in Nigeria during the COVID-19 crisis. For a sample of 1674 households used in the analysis, nearly 32% were moderately food insecure in the baseline survey (ie, the prepandemic period), compared with 74% and 72% that faced the same degree of food insecurity in the two waves of the COVID-19 phone survey. In like manner, not up to 4% of the households faced severe food insecurity in the prepandemic period, compared with 43% and 22% that experienced the same level of food insecurity during the period of the pandemic. Based on the available information in the dataset, we construct a composite non-monetary measure (or index) of household well-being and employ the binary logistic model to investigate the objects under study. The empirical results show that the well-being index has a strong negative association with household food insecurity. Further investigation reveals that the risk of being food insecure increases for households in relatively poor living conditions compared with those in the middle category and conversely declines for households in much better living conditions.
This study informs an understanding of the prevalence and risk of household food insecurity in Nigeria during the novel COVID-19 pandemic and provides insights that can guide policy actions in responding to the current wave of food crises in Nigeria.
本研究旨在利用尼日利亚大流行前面对面调查和两次 COVID-19 全国纵向电话调查（NLPS）的协调数据集，调查尼日利亚在新型 COVID-19 大流行期间家庭粮食不安全的风险。
尼日利亚。
分析中使用了具有代表性的 1674 户家庭样本。
纵向研究。
我们的纵向研究表明，在 COVID-19 危机期间，尼日利亚粮食不安全的发生率显著增加。在分析中使用的 1674 户家庭样本中，近 32%的家庭在基线调查（即大流行前时期）中处于中度粮食不安全状态，而在 COVID-19 电话调查的两个波次中，这一比例分别为 74%和 72%。同样，在大流行前时期，不到 4%的家庭面临严重粮食不安全，而在大流行期间，这一比例分别为 43%和 22%。根据数据集提供的信息，我们构建了一个家庭福利的非货币综合衡量指标（或指数），并采用二元逻辑模型来研究研究对象。实证结果表明，福利指数与家庭粮食不安全状况呈负相关。进一步调查表明，与中等水平的家庭相比，生活条件较差的家庭面临粮食不安全的风险增加，而生活条件较好的家庭面临粮食不安全的风险则降低。
本研究提供了在新型 COVID-19 大流行期间尼日利亚家庭粮食不安全的流行程度和风险的信息，并为应对当前尼日利亚粮食危机提供了指导政策行动的见解。
