Nutrition and COPDWhat 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

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

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

Impact of 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

Identifying Malnutrition

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

Increased energy requirements

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

Chewing and swallowing problems

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”

Oral Nutrition 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

High fat, low carbohydrate Supplements?

Recommended dietary patterns for people with COPD

1-2 servings (palm size) of meat or meat alternatives

2 or more servings of fruit and 3 or more servings of vegetables

2-3 servings of milk and milk alternatives

A serving (about fist size) of carbohydrates at each meal (preferably wholegrain)

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

Bone Health

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

Obesity and COPD

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

Micronutrient Supplements

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.
