Secondary data analysis will be performed as our approach to complete the study. A nationally representative dataset (BRFSS, 2017) will be used to answer our research questions. Our rationale is that there is insufficient research assessing the relationship between pulmonary status and e-cigarette use and that some factors, such as behavioral variables or psychosocial variables, might influence this relationship. Our expectation is that this study will deepen the understanding of the relationship between pulmonary status and e-cigarette use among U.S. adults. This study will cast light on different factors that influence the relationship between pulmonary status and e-cigarette use. Also, the following secondary outcomes will be tested: Severity of COPD symptoms (COPD group) moderate the relationship between pulmonary status (COPD status) and e-cigarette use, and Severity of asthma symptoms (asthma group) moderate the relationship between pulmonary status (asthma status) and e-cigarette use.

Only the study team can determine whether someone qualifies for participation.
This is secondary data analysis, so there is no control over the data (inclusion criteria, and exclusion criteria).

The Behavioral Risk Factor Surveillance System (BRFSS) is health-related telephone surveys that collect state data about United States residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services. This database contains data to help determine e-cigarette use in individuals with pulmonary disease in the US which little is known.
Note: The Behavioral Risk Factor Surveillance System (BRFSS) is a public dataset, and the data is publicly available online at (https://www.cdc.gov/brfss/annual_data/annual_2017.html)
The Behavioral Risk Factor Surveillance System (BRFSS) is a health-related telephone surveys that collect state data about United States residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services (Secondary-data analysis).
Time frame: 1 year
This question assesses mental health, including stress, depression, and emotional problems, by asking participants the number of days out of the last 30 days that their mental health was not good (continuous variables).
Time frame: 1 year
Smoking: This scale assesses the frequency of smoking cigarettes: 1 = every day, 2 = some days, 3 = not at all.
Time frame: 1 year
This survey item asks participants if they ever used an e-cigarette or other electronic "vaping" product, even just one time, in their entire life (Yes/No).
Time frame: 1 year
This question assesses the number of days in the last 30 days that participants have drunk alcohol (continuous variables).
Time frame: 1 year
In reference to healthy days, these questions assess health-related quality of life, which is going to be assessed by asking questions concerning the number of days out of the last 30 days that the participants were physically or mentally ill (continuous variables).
Time frame: 1 year
This question assesses the number of days in the last 30 days that participants have used marijuana or hashish (continuous variables).
Time frame: 1 year
Three questions are posed to assess the severity of COPD symptoms. The responses of these questions are combined to form a composite score. The first question will assess coughing, the second question will assess phlegm production, and the third question will assess shortness of breath. Answers for each of the three questions will be in a yes/no format and will be represented on a scale of 1-3, where 1 is less severe and 3 is more severe.
Time frame: 1 year
Several questions determine the severity of asthma symptoms. The first question will assess the asthma symptoms by asking the participants the number of days they were unable to work or carry out their usual activities because of their asthma symptoms (continuous variables). The second question will assess coughing, wheezing, shortness of breath, chest tightness and phlegm production by asking participants the number of days out of the last 30 that they have any of the previous symptoms (continuous variables). The final question will symptoms of asthma make it difficult for the participants to stay asleep (continuous variables).
