OBJECTIVE: To investigated the influence of illness perceptions and other risk factors related to poor asthma control and quality of life in adult outpatients with asthma in China.
METHODS: Patients with a confirmed asthma diagnosis were recruited from the outpatient clinic at Zhongshan Hospital, Fudan University in Shanghai. Sociodemographic, psychological, and asthma related variables were assessed in all participants. Patients' illness perceptions, medication adherence, asthma control, and quality of life were assessed using validated questionnaires, such as the Brief Illness Perception Questionnaire, Medication Adherence Rating Scale (MARS-A), the Asthma Control Test, and the Mini Asthma Quality of Life Questionnaire. Multiple linear regressions and logistic regressions were used to examine the associations between illness perceptions, medication adherence behaviors, and disease outcome (i.e., asthma control and quality of life).
RESULTS: A total of two hundred thirty-one (231) outpatients with asthma were included in this cross-sectional study, 80 of whom (34.6%) had asthma that was uncontrolled. Patients who perceived their life (β = - 0.197, p < 0.001) and emotions (β = - 0.294, p < 0.001) as severely affected by the illness were more likely to have a lower quality of life, findings that were statistically significant. Also, patients who believed they had a higher degree of personal control over their illness (β = 0.333, p < 0.001), and had better medication adherence (β = 0.250, p < 0.001) were found to have a better quality of life.
CONCLUSION: Our study indicated that illness perceptions and medication adherence have a significant impact on disease outcome. Both of these factors should be considered when determining the best health care practices or constructing a predictive intervention model for patients with uncontrolled asthma.
