Background and Objectives: Malnutrition is frequent in hospitalized older adults, favoring nutritional deficiencies, such as anemia. Several studies have associated anemia with reduced performance in daily activities, which may increase morbidity and mortality. This study aimed to assess the relation between anemia and older adults’ nutritional status. Methods: This is a cross-sectional study with hospitalized older adults. Anemia was investigated via hemoglobin. The chosen outcome variables were anemia and hemoglobin and the exposure variables gender, age group, skin color, marital status, education, and nutritional status. Variables were described in absolute and relative frequencies. For statistical analysis, the Chi-square and ANOVA tests were used. Results: Overall, we evaluated 272 hospitalized older adults and fund a 65.1% prevalence of anemia. We associated anemia with age group, malnutrition, and decreased muscle mass. Hemoglobin levels decreased as participants’ nutritional status worsened, with malnutrition showing the lowest average. Conclusion: Anemia was associated with nutritional status by the evaluated instruments and we observed a reduction in hemoglobin levels as volunteers’ nutritional status worsened. Therefore, research must understand the factors associated with anemia, and healthcare providers should investigate anemic older adults’ clinical history anemic to search for its basic cause.
