Abstract

In Brief PURPOSE: Individuals with severe chronic obstructive pulmonary disease are frequently characterized as cachectic and suffering from generalized weight loss and muscle wasting. Loss of body mass is associated with disability and premature mortality, and body mass index (BMI) has been used as a marker for nutritional status and to predict survival. This cross-sectional study evaluated the association between BMI (kg/m2), nutritional intake, strength, and function in 19 elderly (70 ± 1 years) men and women (BMI = 27.8 ± 1.1 kg/m2) enrolled in a pulmonary rehabilitation program. METHODS: Three-day prospective diet records were collected and analyzed using Food Processor software. Upper and lower body strength was measured using 1 repetition maximum testing for chest and leg press. Function (endurance, strength, and power) was assessed using the Senior Fitness Test battery (6-minute walk, up-and-go, chair stand, arm curl). RESULTS: BMI was positively associated with upper (P < .05) and lower (P < .01) body strength but was not related to nutrition or function. Total daily caloric (kcal/d), protein (g/d), and carbohydrate (g/d) intakes were positively related to upper body strength (P < .01, P < .01, and P < .05, respectively) and lower body strength (P < .05, P < .05, and P < .05, respectively) and 6-minute walk (P < .05). Fat intake (g/d) was positively related to upper body strength (P < 0.05) alone. CONCLUSIONS: Despite health concerns regarding obesity and overweight, clinicians should consider the impact of BMI and dietary intake before initiating weight loss interventions in patients with chronic obstructive pulmonary disease. In elderly patients with chronic obstructive pulmonary disease, body mass index and nutritional intake were strongly related to strength, but only nutrition was related to function. Results suggest that although adequate long-term nutrition is needed to maintain body mass index and strength, adequate short-term nutrition is needed for function.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
