Summary

Nutritional support did not improve lung function, exercise capacity, or body measurements in patients with stable chronic obstructive pulmonary disease (COPD). This meta-analysis found no significant benefits from caloric supplementation for at least two weeks.

Area of Science:

  • Pulmonary Medicine
  • Nutritional Science
  • Clinical Research

Background:

  • Malnutrition in COPD patients is linked to worse outcomes, including reduced exercise capacity and higher mortality.
  • Nutritional support is considered a potential component of comprehensive COPD care.

Purpose of the Study:

  • To evaluate the effectiveness of nutritional supplementation in stable COPD patients.
  • To determine if caloric supplementation (≥2 weeks) improves anthropometric measures, pulmonary function, respiratory muscle strength, and exercise capacity.

Main Methods:

  • A meta-analysis of randomized controlled trials (RCTs) was conducted.
  • RCTs were identified through comprehensive literature searches and expert consultation.
  • Data from nine high-quality RCTs were pooled using a random-effects model.

Main Results:

  • Nutritional support showed a small effect across all studied outcomes.
  • The 95% confidence intervals for all pooled effect sizes included zero, indicating no statistically significant improvement.
  • The effects of nutritional support were consistent across the included studies.

Conclusions:

  • Nutritional support does not improve anthropometric measures, lung function, or functional exercise capacity in stable COPD patients.
  • Current evidence suggests caloric supplementation is not beneficial for these outcomes in this population.
