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. We used two kinds of scores for assessment of dietary diversity. At first, dietary diversity was determined using DVS calculated from answers to a questionnaire about frequencies of intake of 10 food groups. Second, dietary intake was assessed using a 3-day dietary record with photographs, and dietary diversity was determined using QUANTIDD. The relationships between DVS and QUANTIDD were assessed using partial correlation coefficients controlling for confounders. The correlation coefficient between DVS and QUANTIDD was moderate (r = 0.212-0.458). After controlling for confounders, those correlation coefficient between DVS and QUANTIDD remained moderate. The findings suggest that there was a moderate relationship between DVS and QUANTIDD, and DVS using a short-form questionnaire may be useful for assessing dietary diversity in older Japanese community dwellers.
