Short Actives Lives Survey is a common tool used to measure physical activity in the UK population. Self-reported measures such as the Short Active Lives Survey can be prone to bias. As such, during project evaluations, benefits may be exaggerated due to over-reporting of physical activity or downplayed due to underreporting of physical activity. There is also a lack of research reporting the typical short-term and long-term changes in physical activity (measured by the Short Active Lives Survey) in people with chronic lung conditions who are not receiving support to become active (i.e. usual care, control groups). Accelerometers are small lightweight activity monitors that can be worn on the waist. These monitors are known to provide accurate and reliable objective assessment of physical activity in people with lung conditions.

This research study will recruit a cohort of inactive people with lung conditions and determine changes in physical activity measured by both the Short Active Lives Survey and one of the most valid accelerometers used in people with lung conditions (Actigraph GT3X). The study will also evaluate how these physical activity measures relate to general health (health status and health care use) of people with lung conditions over 12 months. This study will provide information on the usefulness of using the Short Active Lives Survey in the future for measuring physical activity in people with lung conditions.

Inclusion Criteria:

• Diagnosis of Chronic Obstructive Pulmonary Disease, Bronchiectasis, Interstitial Lung Disease, Lung Cancer, Mesothelioma or Asthma
• Physically inactive defined as completing less than 30 minutes ore more of moderate intensity equivalent physical activity per week (measured by the Short Active Lives Survey)

Exclusion Criteria:

• Adults without a diagnosis of Chronic Obstructive Pulmonary Disease, Bronchiectasis, Interstitial Lung Disease, Lung Cancer, Mesothelioma or Asthma
• Age < 18 Years
• Completing 30 minutes or more of moderate intensity equivalent (MIE) physical activity per week
• Inability or unwillingness to sign informed consent

The eligibility criteria has been designed to be as broad as possible so that findings can be generalisable to the wider population of inactive people with lung conditions. The main study population will be recruited via convenience sampling at the participant identification centres within Lincolnshire Community Health Services, South Lincolnshire CCG, South West Lincolnshire CCG, Lincolnshire East CCG, Lincolnshire West CCG and United Lincolnshire Hospitals NHS Trust.
