The Dietary Screening Tool (DST) was developed and validated to assess nutritional risk in older adults. The purpose of this study was to assess its use in a middle‐aged sample of adults (45–64 years) in Appalachia (n=87) and evaluate its validity with multiple 24‐hour dietary recalls and selected biomarkers. Adults identified by the DST as at nutrition risk (<60 of 100 points) were significantly more likely to have had lower overall diet quality as assessed by the Healthy Eating Index (64 vs 50, p<0.001) when compared to those not at risk or potential risk. Dietary intakes of vitamin A, vitamin C, vitamin B2, vitamin B6, niacin, vitamin K and potassium were also lower among those considered at risk, despite having significantly higher energy intakes (1653 ± 106 vs 2032 ± 76 kcal/day, p=0.004). The diets of those at risk were higher in added sugars (33 g vs 23 g, P=0.005) and lower in dietary fiber (10 g vs 12 g, p<0.001) than those not at risk. The at risk group had significantly lower serum levels of 13‐cis‐β carotene (40 vs 60 nmol/L, p<0.02), trans‐ β‐carotene (395 vs 711 nmol/L, p<0.001), β‐Cryptoxanthin (137 vs 198 nmol/L, p<0.01), cis‐Lutein (90 vs 137 nmol/L, p<0.02), and trans‐lutein (292 vs 424 nmol/L, p=0.01). The DST was able to identify middle‐aged adults at nutritional risk.
