Dietary diversity and food choice motives during the COVID-19 pandemic among older Japanese: An Internet Panel Survey.

Background And Objectives: We examined how food choice motives and dietary habits changed during the COVID-19 pandemic.

Validity of dietary diversity assessed using short-form questionnaire among older Japanese community dwellers.

The validity of dietary variety score (DVS) using a short-form questionnaire has not been investigated using dietary diversity based on a quantitative distribution of consumed foods in older Japanese. We examined the association between DVS and objective dietary diversity using a Quantitative Index for Dietary Diversity (QUANTIDD) based on the quantitative distribution of foods consumed by older Japanese community dwellers. The subjects were 65 older Japanese community dwellers aged 60?79 years.
