Factors associated with household food insecurity and dietary diversity among day laborers amid the COVID-19 pandemic in Bangladesh

BACKGROUNDS: Food insecurity and dietary diversity remain a public health concern in developing countries like Bangladesh which is exacerbated by the COVID-19 especially for day laborers’ families in Bangladesh. This study aimed to determine factors associated with household food insecurity and household dietary diversity among day laborers during the COVID-19 pandemic in Bangladesh. METHODS: This cross-sectional study was conducted among 343 households of day laborers in Bangladesh using a semi-structured questionnaire. Household food security (HFS) and Household dietary diversity (HDD) scores were assessed using the HFS scale and household’s 24-h recall of intake of 12 food groups, respectively. RESULTS: The overall mean scores of HFS and HDD were 26.80 (SD, 4.83) and 4.08 (SD, 1.15). Having household head aged > 40 years and monthly household income > 5000 Bangladeshi Taka (BDT) were positively associated with HDD scores. Having an education level above secondary, monthly household income > 5000 BDT, and having a refrigerator were associated with the higher HFS scores, whereas having family members > 5 was a potential determinant of lower HFS scores. Pandemic-induced work loss and food scarcity were also potential determinants of lower HFS and HDD scores. Approximately 94% of respondents reported their wages were reduced, and 76% were deprived of the same quantity of food as pre-pandemic periods. CONCLUSIONS: Lower socio-economic status and pandemic-induced work loss affect the HFS and HDD. Interventions with financial aid and complemented food distributions, particularly among the wage looser, may improve the HFS and HDD of day laborers.
