Abstract: Objective: This study aimed to investigate the level of haze-related knowledge adolescents have and to explore relevant influencing factors. Methods: From June 2015 to January 2016, researchers randomly selected 2 districts from the 20 districts of Baoding, China. Then, researchers randomly selected 2 middle schools from 2 districts. By conducting a stratified cluster sampling and considering one class as a unit, researchers randomly selected, from the other middle school, 5 first-grade classes, 5 second-grade classes, 5 third-grade classes from the one middle school and 3 first-grade classes, 2 second-grade classes, 2 third-grade classes. Finally, 1100 adolescents were investigated by using the demographic questionnaire and the Adolescent Haze-related Knowledge Awareness Assessment Scale (AHRKAAS). Multiple linear regressions were conducted to explore factors affecting the adolescent haze-related knowledge. The sensitivity analysis was used to confirm associations between influencing factors and AHRKAAS scores. Results: AHRKAAS score rate was 69.9%. The dimension of human factors of haze formation was the highest (score rate=85.6%). The dimension of haze harms on the human body was the lowest (score rate=57.1%). Compared with the group (monthly expenses <300 yuan), the group (monthly expenses ≥600 yuan) had a higher AHRKAAS score (β=4.882, 95% CI: 0.979, 8.784). Compared with the group (Do not live with parents), the group (Live with parents) had a higher AHRKAAS score (β=14.675, 95% CI: 9.494, 19.855). Compared with the group (Never undergo a physical examination), the group (Once a year) (β=7.444, 95% CI: 2.922, 11.966) and the group (A few times a year) (β=7.643, 95% CI: 2.367, 12.919) had a higher AHRKAAS score. Compared with the group (Know nothing), the group (Know most) (β=9.623, 95% CI: 2.929, 16.316) and the group (Know very well) (β=15.367, 95% CI: 7.220, 23.515) had a higher AHRKAAS score. These associations were still reliable and consistent in different sensitivity analysis models. Conclusion: The level of adolescent haze-related knowledge is low and is affected by monthly expenses, living condition, physical examination frequency, and knowledge of respiratory system diseases. Government bodies, schools and research institutions should strengthen cooperation of health publicity and health education to improve adolescent haze-related knowledge.
