Effect of individual nutritional therapy during inpatient pulmonary rehabilitation in patients at risk for malnutrition and sarcopenia - a randomized controlled trial
BackgroundMalnutrition and sarcopenia are common in inpatient rehabilitation, however individual nutritional therapy (iNT) is often underutilized. This study aimed to assess the effect of iNT on nutrition and muscular health.MethodPatients with chronic obstructive pulmonary disease (COPD) or post-pneumonia at risk for malnutrition and sarcopenia undergoing inpatient rehabilitation were enrolled. The control group received usual care including enriched food and educational group sessions on nutrition. The intervention group received additional counselling by a dietician twice a week. Both groups received individualized physiotherapy and self-management coaching, endurance exercise sessions on 5 days and strength training sessions on 2-3 days per week as part of the clinical routine. Primary outcomes were changes in energy and protein intake, assessed via menu consumption and macronutrient analysis. Secondary outcomes included handgrip strength, muscle mass by bioimpedance analysis, and physical performance measured by the timed-up-and-go test.ResultsTwenty-six patients per group (median age of 72 years, 60% men, 52% COPD) were included. Energy and protein intake increased significantly more in the intervention group with a 309 kcal and 16 g compared to -53 kcal and -1 g in the control group (p = 0.001 for group differences). Handgrip improved more in the intervention group by a median of 1 kg (p = 0.007), without group differences in muscle mass or physical performance.ConclusionINT effectively increased energy and protein intake in patients at risk of malnutrition and sarcopenia undergoing 3 weeks of pulmonary rehabilitation, with a positive impact on prognostic handgrip strength.Trial registrationThe study was registered by the US National Institutes of Health (ClinicalTrials.gov). # NCT05096013.
This research output has an Altmetric Attention Score of 8. 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 27 September 2026.
All research outputs
#6,608,218
of 34,407,356 outputs
Outputs from Chronic Respiratory Disease
#167
of 657 outputs
Outputs of similar age
#64,104
of 357,173 outputs
Outputs of similar age from Chronic Respiratory Disease
#2
of 9 outputs
Altmetric has tracked 34,407,356 research outputs across all sources so far. Compared to these this one has done well and is in the 80th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 657 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.3. This one has gotten more attention than average, scoring higher than 74% of its peers.
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 357,173 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 82% of its contemporaries.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
