Objective:

To analyze the association between the presence of anti SARS-CoV-2 antibodies and other household characteristics and the food insecurity in a national sample of Mexican households.

Materials and methods:

The relation between food insecurity (FI) and household characteristics was established through ordinal logistic regression, multinomial regression models were used to study the self-reported changes in food consumption and FI in the presence of antibodies against SARS-CoV-2 in at least one inhabitant of the household.

Results:

Households with seropositive cases shown a lower meat consumption. In those households which suffered an income reduction and had at least one individual positive for anti SARS-CoV-2 antibodies, the FI -in its higher levels- worsened (OR=1.225; CI95%: 1.04, 1.44).
