Symptoms of chronic obstructive pulmonary disease (COPD) and high body mass index (BMI) overlap. The investigators are trying to find out if a program proven to help people lose a modest amount of weight and increase their physical activity will improve COPD symptoms for those with a high BMI. The program uses a series of video sessions and self-study handouts focused on healthy eating and increasing physical activity, and encourages participants to monitor their weight, diet, and physical activity for one year. For those who want to, they will be able to work with a health coach to help meet weight and activity goals. We hope that the program will lead to improved exercise tolerance, body weight, dyspnea, generic health-related quality of life, and major cardiovascular risk factors (central obesity by waist circumference, Framingham Risk Score, and blood pressure) through 12 months of follow-up. To be in the study, participants will need to have COPD, high BMI, history of smoking, shortness of breath, and be at least 40 years old.

Short Form 12 Health Survey (SF-12) Physical Component Score (PCS)
scores range from 0-100 with higher scores reflecting better health

Non-laboratory Framingham Risk Score
This measure uses non-laboratory-based measures (sex, age, body mass index, systolic blood pressure, use of antihypertensive treatment, smoking status, and diabetes status) to yield a score (cardiovascular disease points) representing 10-year risk of having a cardiovascular problem. Low scores (minimum of -2 for women, -3 for men) indicate low risk. Scores of 21 or higher indicate high risk (30% risk or higher).
Time frame: 12 months
Waist Circumference
cardiovascular disease risk
Time frame: 12 months
Systolic Blood Pressure
indicator of cardiovascular disease risk; higher values indicate higher risk
Time frame: 12 months
Body Mass Index (BMI)
cardiovascular disease risk
Time frame: 12 months
St George's Respiratory Questionnaire For COPD Patients (SGRQ-C) Symptom Component Score
Designed to measure respiratory health quality of life in patients with COPD, providing a total score and three subscale scores assessing: (1) symptoms (frequency and severity), (2) activities that cause or are limited by breathlessness and (3) Impact (social functioning and psychological disturbances resulting from COPD). Each score ranges from 0-100, with higher scores indicating more limitations.
Time frame: 12 months
St George's Respiratory Questionnaire For COPD Patients (SGRQ-C) Activity Component Score
Designed to measure respiratory health quality of life in patients with COPD, providing a total score and three subscale scores assessing: (1) symptoms (frequency and severity), (2) activities that cause or are limited by breathlessness and (3) Impact (social functioning and psychological disturbances resulting from COPD). Each score ranges from 0-100, with higher scores indicating more limitations.
Time frame: 12 months
St George's Respiratory Questionnaire For COPD Patients (SGRQ-C) Impact Component Score
Designed to measure respiratory health quality of life in patients with COPD, providing a total score and three subscale scores assessing: (1) symptoms (frequency and severity), (2) activities that cause or are limited by breathlessness and (3) Impact (social functioning and psychological disturbances resulting from COPD). Each score ranges from 0-100, with higher scores indicating more limitations.
Time frame: 12 months
St George's Respiratory Questionnaire For COPD Patients (SGRQ-C) Total Score
Designed to measure respiratory health quality of life in patients with COPD, providing a total score and three subscale scores assessing: (1) symptoms (frequency and severity), (2) activities that cause or are limited by breathlessness and (3) Impact (social functioning and psychological disturbances resulting from COPD).
