The aims of this study were to (1) compare diet quality between patients with heart failure (HF) and age- and sex-matched community-dwelling healthy older adults and (2) determine whether having HF was associated with a lower Healthy Eating Index-2015 (HEI-2015) score and risk of micronutrient deficiency. The HEI-2015 and macro- and micronutrient intakes of patients with HF were compared with healthy older adults (N 102; 55–92 years old; 53 % female). A paired t-test or Wilcoxon singed-rank test, McNemar’s test, and conditional logistic regression were used to assess the association between diet quality and HF status. Median values for HEI-2015 and the number of micronutrient deficiency were used to dichotomise into groups in the conditional logistic regression. There was no significant between-group difference in the HEI-2015 total score (P 0.059), whereas the whole grain component was lower in patients with HF than in healthy older adults (3.1 ± 3.5 v. 4.5 ± 3.1, P 0.037; respectively). Total caloric intake was lower in patients with HF than in healthy older adults (1683 ± 595 v. 2104 ± 670 kcal; P < 0.001). Patients with HF had a higher average number of micronutrient deficiencies than healthy older adults (4[2, 6] v. 1[0, 4], respectively, P < 0.001). Patients with HF had four times higher odds of being in a high micronutrient deficiency group than healthy older adults, controlling for socio-demographics and body mass index (adjusted odds ratio [95 % confidence interval]: 4.04[1.06, 15.41]). Our findings demonstrate that diet quality measured by nutritional intake identifies patients with HF with lower caloric intake and higher micronutrient deficiencies compared with age- and sex-matched healthy older adults.
