ABSTRACT
In 2018 the European Working Group on Sarcopenia in Older People (EWGSOP2) updated the definition of sarcopenia, with loss of muscle strength being the primary feature. The objective is to describe and associate sarcopenia and nutritional status in a group of Chilean older adults aged 65 years and older. METHODS: Descriptive, associative and comparative study, with a cross-sectional design and a quanti-qualitative approach. A number of 155 institutionalized and community-dwelling Chilean older people aged 65 years and older participated in the study (year 2018). Sarcopenia was diagnosed using the algorithm proposed by the EWGSOP2. Muscle strength, muscle quantity and physical performance were assessed; Body Mass Index (BMI) and Mini Nutritional Assessment (MNA) were used. Variables were described according to sex and age groups (65-69; 70-79; and ≥80 years). The association between sarcopenia and nutritional status was studied by the application of multivariate logistic regression analysis with adjustments for age and sex. RESULTS: 49.7% and 5.2% of older adults had probable sarcopenia and severe sarcopenia, respectively; 52.9% and 7% had malnutrition by excess and by deficit, respectively, according to their BMI; and 33.5% had malnutrition according to the MNA. Participants with obesity had 3.2 times more risk of presenting sarcopenia, versus subjects with normal nutritional status (OR: 3.2; 95% CI; 1.24; 8.26). CONCLUSION: Sarcopenia, as defined by the criteria of the EWGSOP2, depends on the nutritional status according to BMI in older people, with obese individuals being at greater risk of suffering from sarcopenia. Nearly 50% had probable sarcopenia, a condition that could be detected early with the purpose of taking preventive measures, such a nutritional approach.

Fundamentos: La hipertensión primaria está subdiagnosticada en pediatría, su prevalencia de 3,5% va enaumento. El objetivo fue establecer diferencias diagnósticas entre las tablas de clasificación de infantes de 0 a9 años de la Atención Primaria de Salud de Chile, basadas en la Rama de Nefrología de la Sociedad Chilena dePediatría, 2021 y la Academia Americana de Pediatría, 2017. Métodos: Estudio comparativo, descriptivo, asociativo, diseño no experimental, transversal. Muestra porconveniencia: 230 escolares de 6 a 8 años de Valparaíso. Se evaluó presión arterial, estado nutricional,perímetro de cintura. Los datos se tomaron en 2015, 2018, 2019. Pruebas Chi-cuadrado, Tau-b Kendall. Resultados: sin diferencias significativas de distribución entre las clasificaciones de la Sociedad Chilena dePediatría y la Academia Americana de Pediatría; hay asociación entre el índice de masa corporal y ambasescalas (rτ = 0,179, p = 0,003; rτ = 0,059, p = 0,323 y rτ = 0,203, p = 0,001; rτ = 0,077, p = 0,192),respectivamente. La escala americana tenía un mejor grado de diferenciación en sus categorías elevada,etapas 1 y 2 y con el perímetro de cintura. (AU)
Background: Primary hypertension is underdiagnosed in pediatric patients, with a prevalence of 3.5% that ison the rise. Objective: To establish differences in the diagnosis of the classification system of the primaryhealthcare network of Chile for children aged 0 - 9 years, based on the guidelines of the Division ofNephrology of the Chilean Society of Pediatrics, 2021, and the American Academy of Pediatrics, 2017. Methods: Comparative, descriptive, associative study, with a non-experimental, cross-sectional design.Convenience sample: 230 schoolchildren aged 6 - 8 years, Valparaiso. Blood pressure, nutritional status andwaist circumference were assessed. Data were collected in 2015, 2018, 2019. Kendall's tau-b and Chi- squaretests were used. Results: there are not significant differences of distribution between the classifications of the Chilean Societyof Pediatrics and the American Academy of Pediatrics; there is an association between body mass index andboth classification systems (rτ = 0.179, p = 0.003; rτ = 0.059, p = 0.323 and rτ = 0.203, p = 0.001; rτ = 0.077, p =0.192), respectively. The American scale shows a better degree of differentiation in the categories high bloodpressure, stage 1 and stage 2, and regarding waist circumference. Conclusions: The American scale shows a better differentiation between categories of classification withrespect to waist circumference. (AU)
