Rationale: Chronic Obstructive Pulmonary Disease  is commonly associated with systemic complications, including muscle wasting, undernutrition, and decreased functional capacity, which significantly impact clinical outcomes. This study aimed to assess nutritional status, body composition, dietary intake, and physical function in  COPD patients.

Methods: This cross-sectional study included 1050 clinically stable COPD patients (mean age 64.3 ± 8.7 years; 68% male). Pulmonary function (FEV₁, DLCO), airway inflammation (FeNO), and physical performance (6-minute walk test, handgrip strength) were assessed. Nutritional status was evaluated using BMI, serum albumin, dietary intake (24-hour recall), and Subjective Global Assessment . Body composition was measured .

Results: Mean FEV₁ was 49.6 ± 18.2% predicted; 61% were GOLD II/III. DLCO was <80% in 71% (mean 62.4 ± 13.5%); FeNO was >25 ppb in 34%. Mean 6MWT distance was 348 ± 96 meters; 42% walked <350 meters. Mean BMI was 22.8 ± 3.6 kg/m²; 38% had BMI <21. SGA grading: A (52%), B (39%), C (9%). Mean dietary intake was 1435 ± 256 kcal and 0.76 ± 0.21 g/kg/day protein; 64% and 58% had inadequate energy and protein intake, respectively. Mean FFMI was 16.7 ± 2.1 kg/m², with 27% below reference cut-off; mean SMM was 21.5 ± 5.6 kg; Mean handgrip strength was 22.4 ± 6.8 kg; 31% had low strength, significantly associated with malnutrition and poor functional status (p<0.001).

Conclusion: This analysis demonstrates a high prevalence of nutritional risk, altered body composition, and reduced muscle strength among COPD patients, which collectively contribute to impaired functional capacity. The integration of comprehensive nutritional and body composition assessments, provides valuable insights for early identification and intervention in this vulnerable population
