Brief summary
Purpose of study: Fruits and vegetables are known for their many health benefits, with research suggesting they may improve respiratory and inflammatory outcomes in people with COPD, However the relationship between fruits and vegetables and COPD is still being explored. This study aims to compare fruit and vegetable intake in participants with COPD versus healthy control participants, with the goal of identifying any significant differences in fruit and vegetable intake between the two groups. By comparing fruit and vegetable consumption levels, this study aims to explore whether individuals with COPD tend to consume fewer servings compared to people without COPD, potentially due to factors related to their COPD, such as reduced appetite, physical limitations, or lifestyle changes influenced by symptoms of their condition. We hypothesise that participants with COPD consume significantly fewer serves of fruits and vegetables compared to healthy controls, and a higher fruit and vegetable intake is associated with fewer respiratory symptoms in individuals with COPD.
Interventions
Two participant groups will be recruited:
• Group one (COPD group): Adults with a physician diagnosis of chronic obstructive pulmonary disease (COPD) as their primary respiratory condition.
• Group two (healthy control group): Adults with no diagnosed respiratory disease.
This study uses a cross-sectional design to examine the relationship between fruit and vegetable intake and COPD outcomes.

Two participant groups will be recruited: • Group one (COPD group): Adults with a physician diagnosis of chronic obstructive pulmonary disease (COPD) as their primary respiratory condition. • Group two (healthy control group): Adults with no diagnosed respiratory disease. This study uses a cross-sectional design to examine the relationship between fruit and vegetable intake and COPD outcomes. After completing a screening questionnaire, eligible participants will receive a link to complete the study questionnaires online via REDCap, accessible both in their web browser and link provided via email. Participants may begin the questionnaires immediately or return to complete them later. The questionnaires will cover topics related to health and wellbeing, including dietary intake, quality of life, and respiratory symptoms. Specifically, participants will be asked about their medical history, medications, COPD symptoms (if applicable), diet, barriers to fruit and vegetable consumption, chronic fatigue symptoms, sleep, food access and insecurity, physical activity, and symptoms of anxiety and depression. Fruit and vegetable intake will be assessed using the Australian Eating Survey. Participation in this study will take approximately 30-60 minutes.
