Nutritional status and its relationship with different dimensions of functional status in patients with chronic obstructive pulmonary disease

摘要

Objective: To investigate whether there is a relationship between nutritional status and limitations in activities of daily living in patients with chronic obstructive pulmonary disease. Methods: A cross sectional study was conducted from July to December 2011 in Santa Catarina . Seventeen chronic obstructive pulmonary disease patients [age (years) = 67?±8; forced expiratory volume in one second (% of the predicted value) = 38.6?±16.1; body mass index (kg/m 2) = 24.7?±5.4] underwent the assessments: pulmonary function (spirometry); functional status (London Chest Activity of Daily Living scale, physical activities in daily life, and Glittre ADL-Test; nutritional status (anthropometry and dual-energy X-Ray absorptiometry). Results: The total score of the London Chest Activity of Daily Living scale correlated with fat-free mass (r=-0.50; p =0.04) and lean mass (r=-0.50; p =0.04). The lying time in physical activities in daily life correlated with bone mineral content (r=-0.50; p =0.04). Nutricional status was not correlated with time spent on Glittre ADL-test. Conclusion: Variables that reflect muscle mass depletion are related to variables of self-reported limitation in activities of daily living. Bone mineral content is correlated with time patients spend lying, reflecting the impact of inactive postures on the nutritional status of these patients.
