This study is a cross-sectional observational study using an internet-based questionnaire survey of adults aged 20 years or older in Japan. Participants will be recruited from an online research panel managed by a survey company. The survey will assess COPD awareness, perceived COPD risk, respiratory symptoms, smoking history, healthcare-seeking behaviors, barriers to seeking medical care.
The primary analysis will examine differences in healthcare-seeking behaviors and barriers to seeking medical care according to perceived COPD risk among individuals at high risk for COPD. Secondary analyses will assess COPD awareness in the general population, associations of smoking history and respiratory symptoms with healthcare-seeking barriers, and patterns of conventional cigarette and heated tobacco product use and perceptions of their health risks.
Descriptive statistics and analyses of associated factors will be performed. No therapeutic intervention or randomization will be conducted.
