Current situation and influencing factors of varicella vaccination among left-behind children aged 4-8 years old in Quzhou / 中国学校卫生

ABSTRACT

Objective@#To understand vaccination coverage and the influencing factors of varicella vaccine (VarV) among left-behind children in Quzhou, which based on protective motivation theory(PMT), so as to provide reference to consolidate VarV vaccination in the next step.@*Methods@#From September to December in 2022, simple random sampling was used to select 628 left-behind children in six counties of Quzhou City. A questionnaire survey on their caregivers was conducted to collect data relating to sociological characteristics and PMT factors, and the influencing factors of VarV were tested by Logistic regression.@*Results@#A total of 628 left-behind children participated in the study. The VarV rate was 69.59%, and 74.83% had received a second dose of VarV. The unvaccinated rate was 30.41%, and caregivers willingness to vaccinate children with VarV was only 10.99%. Logistic regression analysis showed that family relationships, annual household income, number of children in the family, extrinsic rewards and self-efficacy were the influencing factors of VarV among left-behind children ( OR =0.43-3.40， P <0.05). The external reward factor was positively correlated with the vaccination probability ( OR =1.14), and the self-efficacy factor was negatively correlated with the vaccination probability ( OR =0.95).@*Conclusion@#In the context of health education and school promotion, attention should be paid to factors relating to extrinsic rewards and self-efficacy as a means of increasing motivation to seek vaccine protection and improve the use of VarV.
