This paper talks about the profound wide ranging public health impacts of COVID-19 and focused beyond the direct impacts of virus, like food insecurity, child malnutrition, morbidity and mortality through disruptions in health and nutrition services, food supply chains and livelihoods.This paper carried a longitudinal survey in Community-based individuals from 26 blocks in 2 districts in Uttar Pradesh, India with the objective of assessing changes in (household food insecurity )HFI during the pandemic and examined the interlinkages between HFI with child feeding practices and coping strategies using the HFI Access Scale and examined the changes in HFI during the pandemic using the Wilcoxon matched pairs signed-rank tests. Also assessed child feeding practices and coping strategies by HFI status using multivariable regression models.The results showed that HFI increased sharply from December 2019 to August 2020, with 62% households changing the status from food secure to insecure over this period. Children in newly or consistently food-insecure households were found to less likely consume a diverse diet and highlights the need for further investment in targeted strategies and safety nets as part of multisectoral solutions to improve HFI during and after COVID-19
