Determinants of Preventive Health Behavior for Hepatitis B in Pregnant Women: A Cross-Sectional Study

Vertical transmission from mother to child during the perinatal period is a key route of hepatitis B infection. The infection rate among children of mothers who are hepatitis B carriers is high.

This study was designed to investigate the hepatitis-B-related preventive health behavior of pregnant women and related factors.

A cross-sectional study design was used, and 184 pregnant women aged 20 years or above were recruited at obstetrics clinics as participants. The Demographic Characteristics Questionnaire, Hepatitis B Knowledge Questionnaire, Hepatitis B Health Beliefs Questionnaire, and Preventive Health Behavior Questionnaire were used to collect study data between October 2017 and March 2018.

Most of the participants had received a hepatitis B test because of either a pregnancy checkup (38.0%) or a health examination (32.1%), and most (77.7%) were not hepatitis B carriers. Using multiple linear regression, four significant determinants of hepatitis B preventive health behavior were identified, including marital status (β = 2.45, p = .008, 95% CI [0.66, 4.25]), test for hepatitis B infection status (β = -2.83, p = .013, 95% CI [-5.06, -0.60]), hepatitis B knowledge (β = 0.21, p = .001, 95% CI [0.09, 0.33]), and hepatitis B health beliefs (β = 0.11, p < .001, 95% CI [0.05, 0.16]).

The participants who were not married or had never received a hepatitis B test exhibited better hepatitis-B-related preventive health behavior. Moreover, both hepatitis B knowledge and hepatitis B health belief scores were found to relate positively to preventive health behavior. Healthcare providers should strengthen health education in outpatient clinics and provide post-hepatitis B health-related materials in the community. In particular, internet resources such as hepatitis-B-related health education apps and other channels should be used to increase hepatitis B knowledge in perinatal women and eliminate hepatitis B.
