Abstract: Objective To analyze the current status of quality of life and its influencing factors among adolescents with bronchial asthma in Qinhuangdao. Methods A convenience sampling method was used to select adolescents with bronchial asthma who visited a hospital in Qinhuangdao between January 2022 and April 2024. Quality of life was assessed using the Pediatric Asthma Quality of Life Questionnaire (PAQLQ), and descriptive analysis was performed on the survey results. Multiple linear regression analysis was conducted to identify factors influencing quality of life in these adolescents. Results A total of 472 adolescents with bronchial asthma were included. The mean PAQLQ score was (126.25±13.24), with subscale scores of (49.47±5.12) (symptoms), (29.12±3.25) (activities), and (47.66±5.06) (emotions). Multiple linear regression analysis revealed that school absenteeism (β'=0.658), caregiver smoking history (β'=0.428), family history of asthma (β'=0.577), asthma control status (β'=0.512), medication adherence (β'=0.561), anxiety (β'=-0.628), depression (β'=-0.678), and social support (β'=0.362) were independent influencing factors of quality of life (all P<0.01). Conclusions Adolescents with bronchial asthma in Qinhuangdao have poor quality of life, influenced by factors such as school absenteeism, caregiver smoking, family history of asthma, asthma control, medication adherence, anxiety, depression, and social support. Targeted assessments and interventions based on these factors are recommended to improve their quality of life.
