The study revealed that socio-environmental perceptions have a significant impact on the preparedness and knowledge of air pollution risk among adolescent males. Particularly, low environmental knowledge of oneself can negatively influence overall preparedness. Specific preparedness and knowledge are influenced by various factors, indicating the need for targeted environmental and health actions.
Background: Adolescent males are often considered as less medically vulnerable, resulting in less community healthcare but stronger influences of environmental awareness (preparedness and knowledge) on self-preventive strategies of air pollution risk. However, socio-environmental experiences can alter subjective understandings of the environment, thereby modifying their environmental awareness. Method: A two-stage analysis was applied to evaluate the impacts of socio-environmental perceptions on the preparedness and knowledge of air pollution risk among 551 adolescent males. In the first stage, we evaluated the impacts on the overall preparedness and knowledge with Gaussian regressions, and in the second stage, we evaluated specific preparedness and knowledge with binomial regressions. Results: First-stage analyses showed that socio-environmental perceptions impacted overall preparedness but not overall knowledge. Particularly, perceivably low environmental knowledge of oneself negatively influenced overall preparedness, and a perceivably large household positively influenced overall preparedness. The second stage analyses further implied a complex mechanism between perception, preparedness, and knowledge. Specifically, poor outdoor air quality surrounding the home and perceivably low environmental knowledge of oneself negatively influenced specific preparedness for caring for family members. Perceivably low environmental knowledge of oneself also negatively influenced preparedness for outdoor air pollution and knowledge of visibility, wearing masks, cardiovascular diseases, and mortality risk. Poor indoor environment negatively influenced preparedness of wearing a mask. However, participating in few sports activities negatively influenced preparedness for wearing mask, and knowledge of wearing masks, greenhouse gases, and tropospheric ozone, but positively influenced preparedness for outdoor activities during hazy days. Perceivably low school grade positively influenced knowledge of tropospheric ozone. Perceivably low environmental knowledge of the parents and a large household also positively influenced specific preparedness. Poor indoor air quality at home positively influenced knowledge of mortality risk. Conclusions: Due to the complexity of adolescent males? preparedness and knowledge, further environmental and health actions (e.g., community services, environmental education, and health workshops) with appropriate preventive strategies should be targeted and specified.
