    Body fat using bioimpedance in hospitalized patients of Hospital Dos de Mayo, December 2022
    (Universidad Privada Norbert Wiener, 2020-12-04) Callata Martinez, Tarsis Alondra; Mauricio Alza, Saby Marisol
    The Body Mass Index (BMI) is not a sufficient indicator for diagnosing body fat. This study aimed to calculate the body fat percentage using bioimpedance in patients at the Dos de Mayo Hospital in December 2022. The study used a non-experimental, prospective-cross-sectional design and a sample of 137 hospitalized patients. The data collection technique relied on clinical history and information provided by the nutritionist as part of the nutritional care process, including bioimpedance to determine body fat percentage. The results showed that only 48.2% of patients had a normal body fat percentage, 44.5% were diagnosed with elevated body fat, and 7.3% had low body fat. The elevated diagnosis was most prevalent in males (54.1%), with 21.3% having a personal history of diabetes mellitus and cardiovascular diseases. In conclusion, new procedures are needed in clinical nutritional assessment that includes other indicators beyond BMI.

    Critical review: phase angle measured by bioimpedance as a predictor of sarcopenia in adult patients on hemodialysis
    (Universidad Privada Norbert Wiener, 2024-07-11) Méndez Carbajal, Daniel Fernando; León Cáceres, Johanna del Carmen
    Patients have a high prevalence of malnutrition, metabolic disorders, and decreased daily activities, which increases the risk of mortality and decreases quality of life. This secondary research aimed to identify whether phase angle can predict sarcopenia in adult hemodialysis patients. The clinical question was: Can phase angle measured by bioimpedance predict sarcopenia in adult hemodialysis patients? The methodology used was Evidence-Based Nutrition (NuBE). Information gathering was conducted on Scopus, Science Direct, PubMed, Scielo, Medline, Dialnet, and Redalyc, with 48 articles found. Seven articles were selected and critically evaluated using the CASPE tool, with the cohort article titled 'Phase Angle Derived from Bioelectrical Impedance Analysis Predicts Sarcopenia in Maintenance Hemodialysis Patients' being selected, which has a level I evidence and a strong recommendation grade according to the investigator's expertise. The critical review concluded that phase angle is a good predictor of sarcopenia in adult hemodialysis patients.
