Prevalence and associated factors of psychological distress in tuberculosis patients in Northeast China: a cross-sectional study

Background Psychological distress, a major comorbidities of tuberculosis (TB) patients, has posed a serious threat to the progress being made in global TB programs by affecting treatment adherence and health outcomes. However, the magnitude and associated factors of psychological distress have not been fully studied in China. The aim of the current study was to assess the prevalence of psychological distress in TB patients and to further determine the effects of socio-demographic characteristics, health-related variables, substance use status, social support, and experienced stigma on psychological distress. Methods A cross-sectional survey was conducted among TB patients attending three medical institutions in Dalian, Liaoning Province, Northeast China from November 2020 to March 2021. A structured questionnaire was developed to collect data on patients' socio-demographic characteristics, health-related information, substance use status, psychological distress, family function, doctor-patient relationship, policy support, experienced stigma and so on. The binary logistics regression model was used to determine the associated factors of psychological distress. Results A total of 473 TB patients were enrolled in this study, and the prevalence of psychological distress was 64.1%. Binary logistic regression analysis revealed that patients with a middle school education level or above (OR: 0.521, 95%CI: 0.279-0.974), no adverse drug reactions (OR: 0.476, 95%CI: 0.268-0.846), and regular physical exercise (OR: 0.528, 95%CI: 0.281-0.993) were more likely to stay away from psychological distress. However, patients who had a high economic burden (OR: 1.697, 95%CI: 1.014-2.840), diabetes (OR: 2.165, 95%CI: 1.025-4.573), self-rated illness severe (OR: 3.169, 95%CI: 1.081-9.285), perceived poor resistance (OR: 2.065, 95%CI: 1.118-3.815), severe family dysfunction (OR: 4.001, 95%CI: 1.158-13.823), perceived need for strengthen psychological counseling (OR: 4.837, 95%CI: 2.833-8.258), and a high experienced stigma (OR: 3.253, 95%CI: 1.966-5.384) tended to have a psychological distress. Conclusions The study found that the proportion of psychological distress among TB patients was high in Northeast China, and it was influenced by a variety of factors. Effective interventions to reduce psychological distress in TB patients urgently need to be developed, and greater attention should be given to patients with risk factors.
