Background: Malnutrition and poor oral health are common conditions in patients in the hospital. Both conditions are associated with poor systemic health. The present study aimed to assess the relationship between the oral condition and the nutrition status of individuals admitted to a large tertiary hospital.Methods: This cross-sectional study evaluated 364 patients who received a comprehensive dental examination at their hospital bed. An examiner recorded visible plaque index, gingival bleeding index, plaque retentive factors, probing depth, clinical attachment loss, bleeding on probing, number of existing teeth, and prosthesis use. Medical status was assessed by the Charlson Comorbidity Index. The nutrition status was evaluated by the Subjective Global Assessment. Crude and adjusted prevalence ratios were estimated by Poisson regression analysis with robust variance. Results: Patients with moderate to severe malnutrition presented worse oral hygiene (55.83 ± 25.16 vs 64.90 ± 24.28; P < 0.001), more gingival inflammation (24.31 ± 24.13 vs 33.43 ± 27.36; P < 0.001), higher levels of attachment loss (4.22 ± 1.81 vs 4.80 ± 1.83; P < 0.001), and a lower mean number of teeth (14.58 ± 7.45 vs 10.94 ± 6.85; P < 0.001) than patients without malnutrition. In the multivariable analysis, the number of teeth and higher comorbidity index were associated with malnutrition. Conclusions: Poor oral health and medical condition were associated with malnutrition in this single-institution study, and oral condition may be considered an indicator of malnutrition in patients in the hospital. The implications of this study include the need to raise awareness among health professionals of the importance of oral health and nutrition status in adults.

Background: Older patient with type 2 diabetes (T2D) and malnutrition have a greater chance of negative events during hospitalization and a higher risk of mortality. The aim of this study was to investigate nutritional markers as mortality predictors following discharge hospitalized older patients with T2D. Methods: This is a prospective cohort study with follow-up of four years. All patients were subjected to Mini Assessment Nutrition, Subjective Global Assessment, calf circumference, arm circumference and adductor pollicis muscle thickness, obtained all within 48 h of admission. Mortality data were verified by medical registry and analyzed using Cox-proportional hazard models and survival curves. Results: 311 patients were included; the mean age was 71.35 years. There were 113 (36.3 %) deaths in the follow-up period. Nutritional status evaluated according to BMI identified 54.5% (n = 168) were overweight, for other hand the MAN identified 45.7% of patients were at risk of malnutrition and 37.7% malnutrition and the SGA identify 61.7% (n = 192) presented normal nutrition in admission. Malnutrition patients (OR=2.02), with low calf circumference (OR=1.43) or with APMT less than 5th percentile (2.33) were associated with post-discharge mortality. Conclusion: Malnutrition, reduced calf circumference and reduced APMT were nutritional predictors of mortality after hospital discharge in older patients with diabetes
