Abstract
Patients on chronic hemodialysis tend to lose lean body mass and have sedentary behavior.
To compare the level of physical activity and the morphology of the muscles pectoralis major and rectus abdominis of patients on hemodialysis with healthy subjects.
We studied 17 patients and 17 healthy individuals. Muscle thickness were evaluated by ultrasound, and the level of physical activity by the International Physical Activity Questionnaire (IPAQ), long version.
The patients had lower thicknesses of the pectoralis major (5.92 ± 0.35 mm vs. 8.35 ± 0.62 mm, p < 0.001) and rectus abdominis (0.96 ± 0.10 mm vs. 2 21 ± 0.40 mm, p < 0.001) compared to healthy subjects. Patients were physically less active than healthy individuals: 1502.55(788.19-2513.00) MET-minutes/week vs. 2268.0(1680.0-4490,8) MET-minutes/week (p = 0.006); the weekly caloric expenditure of patients was also lower: 1384.0(480,7-2253.7) kcal/kg/week vs. 1680.0(1677.4-4950.0) kcal/kg/week (p = 0.010). The average time spent sitting per week of the patients was higher than in healthy subjects (394.0 ± 33.1 min/day vs. 293.0 ± 38.6, p = 0.009) as well as the average time spent sitting during weekend (460.0 ± 40.1 vs. 201.0 ± 10.7, p = 0.003).
Chronic renal failure patients on hemodialysis have sedentary behavior and lower muscle thickness of the trunk.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 September 2018.
All research outputs
#21,011,157
of 25,806,080 outputs
Outputs from Jornal Brasileiro de Nefrologia
#285
of 383 outputs
Outputs of similar age
#322,986
of 424,239 outputs
Outputs of similar age from Jornal Brasileiro de Nefrologia
#13
of 24 outputs
Altmetric has tracked 25,806,080 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 383 research outputs from this source. They receive a mean Attention Score of 2.7. This one is in the 15th percentile – i.e., 15% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 424,239 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
