Asociación entre el nivel de autovalencia y el estado nutricional en adultos mayores chilenos

Abstract

Introduction: Malnutrition is associated with decreased functional abilities in older adults. Studies in the older adult population have shown a direct association between body mass index (BMI) and functional limitations. Objective: To determine the relationship between the level of autovalence and nutritional status in a sample of elderly Chileans. Methodology: This cross-sectional descriptive quantitative study analyzed a sample of 837 subjects from Los Andes, Chile, through an anonymized database from 2017. For statistical analysis, the Chi-square test was applied with a confidence level of 95%, and the OR was determined to observe the type of association. Results: We found a statistically significant protective association between “normal nutritional status” and “self-valence with risk” (OR= 0.62 p= 0.0012). In addition, we found a protective association between “obesity nutritional status” and “self-valence without risk” (OR= 0.51 p= 0.0001) and a positive association with “self-valence with risk” (OR= 1.54 p= 0.0067) and dependence (OR= 1.68 p= 0.001). Conclusion: A normal nutritional status was associated with a lower risk of dependency in a sample of older adults. Excess malnutrition could be a risk factor for dependence.
