Objectives: The purpose of this study was to explore characteristics related to ambient air pollution health literacy (AAPHL) and to identify groups with lower AAPHL. Methods: A national, cross-sectional study of Taiwanese adults aged 20-70 years was conducted. Data were collected from September 11 to October 22, 2020. We conducted the survey through computer-assisted telephone interviews. In addition, purposive sampling was used in online surveys. A 32-item Chinese version of the AAPHL assessment tool was used in telephone interviews and online surveys. Decision tree modeling was used to ascertain the characteristics of those with low AAPHL. Results: A total of 1,297 telephone interviews and 291 online surveys were completed, and 1,588 questionnaires were analyzed. The data indicated that having high school education, being unmarried, and living in southern Taiwan were associated with low AAPHL. Conclusions: The education level, area of residence, and marital status were the key risk factors affecting AAPHL. People with the identified characteristics should be regarded as the target population for health education interventions to enhance AAPHL levels in the general population and to reduce the impact of ambient air pollution on public health.
