Could the Wheel of Cardiovascular Health Diet Be a Tool for Diet Quality in Nutritional Counseling? Comparison with Healthy Eating Index-2020.

OBJECTIVE: The Wheel of Cardiovascular Health Diet was recently elaborated based on current nutritional recommendations for healthy eating and was made for person-centered nutritional counseling, thus it may be an interesting tool to improve food awareness. However, its validity is yet to be tested. We hypothesized that the self-perception of patients diagnosed with chronic diseases, evaluated by the Wheel of Cardiovascular Health Diet, is satisfactory in assessing the quality of their diets, compared with the Healthy Eating Index-2020. METHODS: This is a cross-sectional analysis of adults with uncontrolled hypertension or type 2 diabetes. The patients answered the Wheel of Cardiovascular Health Diet, and then, based on the food frequency questionnaire, we analyzed the Healthy Eating Index-2020. RESULTS: A total of 330 patients were included in the study: 91.5% had hypertension, 58.5% had type 2 diabetes, and the median age was 58 (50-65) years. The mean difference observed between the percentage of the graphic area assessed by the patients' self-perception from the Wheel of Cardiovascular Health Diet and Healthy Eating Index-2020 was -10.0% (95%CI -35.3 to 15.3), and a moderate correlation was observed. Linear Regression models showed that a 10-point increase in patients' self-perception in the Wheel of Cardiovascular Health Diet is associated with a 2.9% increase (95%CI 2.08 to 3.70) in the diet quality by the Healthy Eating Index-2020 and is associated with lower BMI values: ß = -0.42 kg/m2 (95%CI -0.83 to -0.01). CONCLUSION: The Wheel of Cardiovascular Health Diet performed satisfactorily regarding validity and reliability by BMI and was associated with higher overall dietary quality, with the Healthy Eating Index-2020 as a relative reference.

GLIM criteria for malnutrition diagnosis of hospitalized patients presents satisfactory criterion validity: A prospective cohort study.

BACKGROUND & AIMS: Malnutrition is prevalent among hospitalized patients, but there is no universally accepted consensus regarding its diagnosis. Recently, the Global Leadership Initiative on Malnutrition (GLIM) proposed a new framework for the malnutrition diagnosis and until this moment there is scarce evidence regarding its validity. This study aimed to evaluate the concurrent and predictive validity of GLIM criteria for malnutrition diagnosis in hospitalized patients. METHODS: Prospective cohort study involving adult/elderly hospitalized patients. The malnutrition diagnoses according to Subjective Global Assessment (SGA) and GLIM criteria were performed within 48 h of admission. Patients were followed up until hospital discharge to assess the length of hospital stay (LOS) and in-hospital mortality. Six months post discharge; the patients were contacted to collect the outcomes readmission and death. Agreement and accuracy tests, Cox and Logistic regression analysis were performed for testing criterion validity. RESULTS: 601 patients (55.7 ± 14.8 years, 51.3% men) were evaluated. Malnutrition was diagnosed in 33.9% and 41.6% of patients, by SGA and GLIM criteria, respectively. GLIM criteria presented a satisfactory accuracy, (AUC = 0.842; CI95% 0.807-0.877) with a sensitivity of 86.6%, and a specificity of 81.6%. The presence of malnutrition by GLIM criteria increased the chance of prolonged hospitalization by 1.76 (CI95% 1.23-2.52) times, and the risk of in-hospital deaths by 5.1 (CI95% 1.14-23.14) times. It was also associated with death within six months (RR = 3.96, CI95% 1.49-10.53). CONCLUSION: GLIM criteria for malnutrition diagnosis presented satisfactory criterion validity and should be applied during clinical practice.

Reduced Handgrip Strength in Hospital Admission Predicts Prolonged Hospital Stay and Death but Is Not Accurate to Identify Malnutrition: A Longitudinal Study of Reduced Handgrip Strength in Hospitalized Patients.

BACKGROUND: Malnourished patients present impairment of functionality due to loss of strength and muscle mass. However, the validity of handgrip strength (HGS) in identifying malnutrition and its association with clinical outcomes in hospitalized patients requires investigation. AIMS: Evaluate the accuracy of HGS in identifying malnutrition, its association with clinical outcomes, and the change in HGS in the first 2 weeks of hospitalization. METHODS: A prospective cohort study with adult/elderly patients. Subjective Global Assessment (SGA) was applied in the first 48 hours for malnutrition diagnosis, and HGS was measured in this moment and after 7 and 14 days of hospital admission. HGS <20 kg for females and <30 kg for males was considered reduced. Outcomes of interest were prolonged hospital stay (LOS) and in-hospital death. RESULTS: Six hundred patients (55.75 ± 14.78 years, 51.5% males) were included, 34.0% of them were malnourished (SGA-B or SGA-C), and 37.2% presented reduced HGS. The concordance between reduced HGS and SGA in malnutrition diagnosis was weak (κ = 0.192), and accuracy was not satisfactory (area under the receiver operating characteristic curve = 0.599 [95% CI, 0.551-0.648]). HGS did not change during the hospitalization. Reduced HGS increased by 1.2 times (95% CI, 1.03-1.40) the odds for prolonged LOS and 9.11 times (95% CI, 1.13-73.60) the risk of death. CONCLUSION: Reduced HGS did not present satisfactory accuracy to identify malnutrition, and HGS did not change during the first 14 days of hospitalization, but was associated with prolonged LOS and in-hospital death.
