Asociación entre el agua intracelular de la masa muscular y el riesgo nutricional en mujeres posmenopáusicas de comunidades urbano-marginales de Guayaquil.

Abstract

INTRODUCTION: There are physiological changes that occur in women from the early postmenopausal years. Among the list, alterations at the level of muscle composition stand out, associated with loss of muscle size and weakness. The use of nutritional screening and electrical impedance are non-invasive methods used for the assessment of nutritional status and body composition. Previous studies have proposed the AIC/MM ratio as a predictor of muscle quality, and it is independently associated with nutritional status in postmenopausal women. METHOD: Descriptive, retrospective, cross-sectional, randomly sampled, descriptive study conducted with a total of 175 postmenopausal women with a mean age of 72.34 ± 12.26 years living independently participated in the study. The AIC/MM ratio was calculated with electrical impedance equipment, and nutritional risk was estimated with MNA screening. RESULTS: Only 24.5% of participants (n=42) presented nutritional risk associated with low weight, BMI, lean mass, appendicular muscle mass (p<0.05). The decrease in AIC/MM showed significant correlation with nutritional risk (p<0.05). CONCLUSION: This study proposes that AIC/MM can be a valid to ol to estimate changes in nutritional status in postmenopausal women. And the decrease in AIC content of MM can be used as an indicator of muscle quality, both functional and structural.
