SUMMARY:

Introduction: COVID-19 is a recent illness that has caused awareness in the
scientific community due to its high transmissibility, the variety of the symptoms, and
the unknown consequences in long term. Despite that, a worse prognosis between
the illness and conditions related to body composition, such as obesity and
sarcopenia, has been observed and, therefore, deserves attention, as well as the
methods used to measure the body composition. Objectives: To study the quality of
life, aspects of the disease, and the body composition of post-covid patients,
comparing different methods such as anthropometry, bioimpedance (BIA), and
ultrasound (US) with Dual-Energy X-Ray Absorptiometry (DEXA), evaluating The
correlation and agreement of these methods. Methods: A observational study was
developed, evaluating patients from the post-Covid outpatient in Divinópolis, Minas
Gerais, with the collection of data relating to the quality of life, through the SF-36
questionnaire and the body composition, by BIA, anthropometry, ultrasound, And
Dexa. Results: Concerning body composition, 44% of patients were classified as
obese according to body fat mass index and 8% had an appendicular lean mass
index compatible with low muscle mass measured by DEXA. 64% presented
substantially increased abdominal circumference. About Covid-19, 47.6% needed
hospitalization during the acute phase of the disease, 23.8% required mechanical
ventilation, and 90% were already vaccinated. The quality-of-life data revealed that
the worst-performance aspect was the limitation by emotional aspects (0.00) and the
the physical limitation (25.00) and the best score was mental health (51.05). There
was good reproducibility of the measurements of the adipose and muscular tissue by
US with ICC greater than 0.90 in all anatomical regions. There was a moderate
correlation between the DEXA A / G rate and the circumference of the waist and
between the A / G rate with intra-abdominal fat measured by US (ICC = 0.567 and
0.563), respectively. As for lean mass, there was a positive moderate correlation
between appendicular muscle mass measured by the US and the appendicular lean
mass measured by DEXA, with a Spearman correlation of 0.620. About the
percentage of body fat, only BIA presented an agreement with Dexa by the analysis
of Bland Altman. Conclusion: Changes to the body composition were frequent, with
the quality-of-life data revealing limitations of emotional and physical aspect in
patients. Between body composition tests, BIA presented the best performance in the
evaluation of adipose tissue compared to the gold standard. More widespread
research is needed for the most in-depth knowledge of the characteristics of the postCovid symptomatic population and the validity of methods, such as US to evaluate
body adipose tissue. Development and validation of specific equations for our
population should be stimulated, positively influencing agreement with Dexa.
