Background Reducing diet costs may lead to the selection of energy‐dense foods, such as refined grains, foods high in added sugars and/or fats, which can lower overall dietary quality. Objectives We examined the longitudinal association between the monetary value of the diet (MVD) and the overall dietary quality across sex, race and income groups. Design We used longitudinal data from 1,466 Healthy Aging in Neighborhoods of Diversity Across the LifeSpan (HANDLS) urban adult participants. Healthy Eating Index–2010 (HEI–2010) and Mean Adequacy Ratio (MAR) were computed. A national food price database was used to estimate MVD. Multiple linear regression analyses were conducted linking annual rates of change (Δ) in MVD to ΔHEI‐2010 and ΔMAR, stratifying by sex, race and income groups. Results ΔHEI‐2010 was comparable across socio‐demographic groups, while ΔMAR was higher among women and individuals above poverty. Adjusting for key covariates, ΔMVD was positively associated in both ΔHEI‐2010 and ΔMAR, 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). ΔMVD‐ΔMAR association was stronger in women, mainly influenced by ΔMVD's positive associations with B‐vitamins, copper, calcium, magnesium and phosphorus NARs. ΔMVD‐Δvitamin D NAR's positive relationship was stronger among Whites, while ΔMVD‐Δvitamin 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 individuals living above the poverty threshold.
