Food purchase and consumption behavior during the COVID-19 pandemic lockdown in Bangladesh: association between sociodemographic composition

Background Bangladesh suffered a severe COVID-19 wave from June to August 2021, which forced the government to impose emergency nationwide lockdown measures for three months with discontinuities. The sudden lockdown strongly affected the dietary preferences, financial circumstances, and social interactions of citizens. Methods In this comprehensive study, we collected sociodemographic information as well as data on food purchase and consumption behaviors from 1,350 adults in Bangladesh during the weeks of enforced confinement. The association between the sociodemographic factors (viz., gender, age, education status, income, occupation, and household size) and food purchase and consumption behaviors were determined by conducting bivariate and multivariate logistic regression models reporting as odds ratios. Results The descriptive result reveals that 49.63% of the participants experienced wage reductions, with many people enduring reductions of up to 75%; 12.22% lost their jobs. Besides, a decline in the frequency of shopping was observed by 35.04%; and 24.52% avoided outdoor shopping during the pandemic period. Additionally, 28.74% of participants purchased less overall, while 19.48% purchased significantly fewer items per trip compared to the pre-pandemic period. The multivariate analysis shows a prominent increase in online grocery shopping (OR: 4.03, 95% CI: 2.38-6.83, p < 0.001) and meal delivery services (OR = 5.19, 95% CI = 3.21-7.17, p < 0.001) among higher educated individuals compared to the individuals having no institutional education. The personnel having formal jobs purchased 2.34 times more from online grocery sites (95% CI = 0.34-4.08, p = 0.003) compared to the unemployed one. In contrast, a notable increase in panic buying and stockpiling was observed, driven by scarcity and escalating prices of essential food items. The frequency of meals with families, active engagement in meal preparation, and the exploration of novel recipes also increased notably. Conclusions The consumption of takeaway food and inter-meal snacks increased significantly with the education level of individuals. These findings highlighted that a prolonged pandemic could magnify economic vulnerability in Bangladesh.
