Changes in dietary patterns among Bangladeshi adult population during the COVID-19 pandemic: A web-based cross-sectional study.

Background: The home confinement induced by the COVID-19 pandemic affects individuals' mental wellbeing and increases unhealthy behaviors, such as minimum to no physical activity, overeating, and substance use. Objective: This study aimed to assess the changes in dietary patterns among the Bangladeshi adult population during the COVID-19 pandemic and identify their determinants. Methods: This web-based cross-sectional survey was carried out from 10-17 December 2020 using an e-questionnaire based on Google Forms. A semi-structured e-questionnaire was forwarded to the participants - Bangladesh citizens aged above 18 years - through social media platforms and email in order to collect information about socio-demographic issues and multidimensional dietary patterns. From the initial 817 responses gathered through snowball sampling, 748 responses were retained. Bivariate and multivariate analyses were executed. Results: The findings suggest that 50% of the participants reported a reduction in weight and physical activities, while approximately 52% experienced increased sleep time. One in three participants (31.4%) experienced a decrease in food buying capacity. The findings further indicate that women were 1.65 times more likely to reduce food consumption than men. Meanwhile, employed people were about 34% less likely to increase food consumption than their unemployed counterparts. People who were getting more than 6 h of sleep per day were nearly 61% less likely to increase food consumption than people who slept for less than 6 h per day. People struggling to buy food items were 2.31 times more likely to reduce food intake than people with no such limitations. Conclusions: The study shows that COVID-19 has substantially affected Bangladeshi people's common food consumption patterns. Being confined within the household, primarily due to countrywide lockdowns and 'general holidays', has affected both the dietary patterns and the financial wellbeing of people. Therefore, the concerned authorities should promote effective nutrition education and healthy dietary behaviors; meanwhile, financial support or incentives for people in need are also strongly advocated.
