Psychological stress; knowledge, attitude and practice and acceptance of antiviral therapy in pregnant women with hepatitis B in Zhejiang, China: a case comparison study

OBJECTIVES: To determine knowledge, attitude and practice (KAP) and antiviral therapy’s acceptance during pregnancy of pregnant women with hepatitis B and influencing factors. DESIGN: Case-comparison study. SETTING: The study was conducted in Zhejiang province, China, from September 2019 to December 2020. PARTICIPANTS: Pregnant and postpartum women with chronic hepatitis B. PRIMARY AND SECONDARY OUTCOME MEASURES: The stress scores, self-assessed health score, KAP, antiviral therapy’s acceptance rate during pregnancy and influencing factors were analysed. The Perceived Stress Scale-10 was used to assess stress. Logistic regression was used to analyse influencing factors on antiviral therapy. RESULTS: The self-assessed health score of pregnant women without liver diseases (82.4±9.3) was significantly higher than that of pregnant women with chronic hepatitis B (75.5±9.5) and postpartum (75.1±14.1). Psychological stress of pregnant women with chronic hepatitis B was significantly high with a 14.9±3.6 score, but there was no significant difference between hepatitis B postpartum and non-liver disease women (12.7±3.5 vs 12.9±3.5, p=0.75). The acceptance rate of pregnant women with hepatitis B for antiviral therapy was 84.2%, while that of postpartum women was even higher. Logistic regression analysis showed that patients with positive hepatitis B e antigen (HBeAg) (OR, 3.35; 95% CI, 1.21 to 9.26) and higher scores on hepatitis B-related knowledge (OR, 3.52, 95% CI, 2.18 to 5.69) were more likely to accept antiviral therapy during pregnancy. CONCLUSIONS: Pregnant women with hepatitis B in Zhejiang have heavy psychological stress and a high antiviral therapy acceptance rate during pregnancy. Acceptance is related to HBeAg status and level of understanding of hepatitis B during pregnancy. It is necessary to provide education on hepatitis B to reduce psychological stress and increase acceptance of antiviral therapy during pregnancy.
