Abstract(s)
Background: This study aimed to analyze the prevalence of sarcopenia in elderly people
from Northern Brazil according to muscle weakness or walking slowness. Methods: The sample
consisted of 312 elderly people (72.6 ± 7.8 years). For walking slowness, a gait speed ≤ 0.8 m/s was
used as a cut-off value, and for muscle weakness the following handgrip strength criteria were used
for men and women, respectively: CI: <27.0/16.0 kg; CII: <35.5/20.0 kg; CIII: grip strength corrected
for body mass index (BMI) < 1.05/0.79; CIV: grip strength corrected for total fat mass: <1.66/0.65;
CV: grip strength corrected for body mass: <0.45/0.34. Results: Walking speed was reduced in 27.0%
of women and 15.2% of men (p < 0.05). According to grip strength criteria, 28.5% of women and
30.4% of men (CI), 58.0% of women and 75.0% of men (CII), 66.0% of women and 39.3% of men
(CIII), 28.8% of women and 19.6% of men (CIV), and 56.5% of women and 50.0% of men (CV) were
identified as having sarcopenia. Conclusions: Walking slowness is more prevalent in women and
muscle weakness is more prevalent in men in Northern Brazil. Walking slowness proved to be more
concordant with muscle weakness in both sexes when the CI for handgrip strength was adopted.
