  1. Nutrition and COPD What we will cover: Malnutrition and COPD Oral nutrition supplements Recommended dietary patterns for people with COPD Bone Health Obesity Micronutrient supplements Katherine Stern Dietitian 10/10/2014

  2. Malnutrition • Malnutrition is more prevalent in people with COPD • 25-40% of patients with COPD are malnourished • Observational studies suggest being underweight (<BMI <18.5-20) is associated with increase disease severity and poorer prognosis. ESPEN Guidelines 2006

  3. Impact of Malnutrition • Reduced ability to fight infections • Impaired wound healing, longer hospital stays and recovery time • Muscle wasting- reduced ability to do usual activities and lower exercise capacity • Impaired temperature regulation ‘feeling the cold’ • Micronutrient deficiencies BAPEN 2012

  4. Identifying Malnutrition • Malnutrition can be described as: • 5% unintentional weight loss in 3 months • 10% unintentional weight loss in 6months • Underweight <BMI 18.5-20 • Muscle and fat wasting PEN (Practice-based Evidence in Nutrition )2010

  5. Increased energy requirements Varied total energy requirements due to differences in resting energy expenditure and physical activity. Estimated 5-10% increase in resting energy expenditure in acute COPD exacerbations. PEN (Practice-based Evidence in Nutrition )2010

  6. Chewing and swallowing problems Reduced intake due to chewing/swallowing problems secondary to breathing problems Small frequent meals Soft, easily chewable foods Convenience foods/ foods that require little preparation Meals on Wheels, other provides e.g. Eat

  7. Oral Nutrition Supplements The most recent systematic reviews and meta-analysis’s have shown a benefit of nutritional supplements for people with COPD. Systematic Review in The American journal of clinical nutrition 2012 Cochrane Systematic Review 2012 “ Moderate quality evidence that nutritional supplements promote weight gain among patients with COPD, especially if undernourished”

  8. High fat, low carbohydrate Supplements? Pulmocare supplement- available on special authority for people with COPD and hypercapnia CO2 >55mgHg Theory: fat produces less CO2 per O2 molecule consumed than carbohydrate decrease respiratory quotient (RQ) Conflicting evidence of a benefit on improved lung function in individuals with COPD ESPEN 2006/ PEN 2010

  9. Recommended dietary patterns for people with COPD 1-2 servings (palm size) of meat or meat alternatives A serving (about fist size) of carbohydrates at each meal (preferably wholegrain) 2-3 servings of milk and milk alternatives 2 or more servings of fruit and 3 or more servings of vegetables

  10. Bone Health Osteoporosis and bone fracture risk higher in people with COPD. Especially important if on steroids, low BMI, low fat free mass, older adult >65+ Adequate calcium sources- 3 or more serving Adequate Vitamin D- consider supplements PEN (Practice-based Evidence in Nutrition )2010

  11. Obesity and COPD • People with stable COPD and obesity may benefit from weight reduction. • Extra weight may worsen exercise tolerance and increase dyspnea. • Weight reduction may be more beneficial for those with OSA and Asthma. • Encourage increased exercise alongside dietary changes to prevent losses of muscle mass PEN (Practice-based Evidence in Nutrition )2010

  12. Micronutrient Supplements Studies have not shown a benefit or lack of studies to support supplementation for Vitamin C, E, beta-carotene, selenium, magnesium, omega 3 and omega 6. Vitamin D- consider supplementation for bone health Comprehensive Multivitamins e.g. Centrum if poor intake PEN (Practice-based Evidence in Nutrition )2010

  13. Summary Achieving adequate nutrition can be a challenge for some people with COPD and malnutrition in common in this patient group Recent meta-analyses have shown a benefit of nutritional supplements Ensure adequate intake of calcium sources and consider vitamin D supplementation Consider weight reduction for those with obesity and stable COPD.
