BACKGROUND: Reducing diet costs may lead to the selection of energy-dense foods, such as refined grains or foods high in added sugars and/or fats, which can lower overall dietary quality. We examined the longitudinal association between the monetary value of the diet (MVD) and the overall dietary quality across sex, race and income groups. METHODS AND FINDINGS: Longitudinal data from 1,466 adult urban participants from Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study were used. Healthy Eating Index-2010 (HEI-2010) and Mean Adequacy Ratio (MAR) were computed and a national food price database was used to estimate MVD. Multiple linear regression analyses were conducted linking annual rates of change (Delta) in MVD to DeltaHEI-2010 and DeltaMAR, stratifying by sex, race and income groups. Among key findings, DeltaHEI-2010 was comparable across socio-demographic groups, while DeltaMAR was higher among women and individuals above poverty. Adjusting for key covariates, DeltaMVD was positively associated with both DeltaHEI-2010 and DeltaMAR, and with a consistently stronger association among individuals above poverty, specifically for the total proteins and empty calories components of HEI-2010 and several nutrient adequacy ratios (NARs: vitamins C, E, B-6 and Zinc). DeltaMVD-DeltaMAR association was stronger in women, mainly influenced by DeltaMVD's positive associations with B-vitamins, copper, calcium, magnesium and phosphorus NARs. DeltaMVD-Deltavitamin D NAR's positive relationship was stronger among Whites, while DeltaMVD-Deltavitamin B-12 NAR's association was stronger among African-Americans. CONCLUSIONS: In sum, a potential increase in MVD may have a stronger impact on dietary quality among urban adult women and above-poverty individuals.
