Abstract：Objective To investigate the vaccination situation among left-behind and non-left-behind children in immunization program in Yueyang City and explore its influencing factors, so as to provide a basis for formulating immunization strategies. Methods A two-stage sampling method based on the concept of probability proportional to size was adopted to select children aged 2-3 years in Yueyang City in 2014. A questionnaire about vaccination of children in immunization program was employed to conduct household surveys on the situation of having vaccination card or certification and routine/booster vaccination among the children. Unconditioned logistic regression analysis was performed to identify the factors affecting the vaccination rate. Results A total of 1,650 children were investigated, including 746 (45.2%) left-behind children and 904 (54.8%) non-left-behind children. The guardians were mainly parents (57.5%, 949/1,650) or grandparents (41.8%, 690/1,650). Most of the parents had an educational background of high school or technical secondary school (81.1%, 770/949), while most of the grandparents an educational background of junior middle school and below (99.71%, 688/690). The coverage rate of five routine vaccines (92.80% vs. 97.00%, χ2=15.83, P<0.05) and whole course vaccination rate (87.30% vs. 90.40%,χ2=4.03, P=0.045)of left-behind children were lower than those of non-left-behind children. For the left-behind children, the coverage rate of five routine vaccines was higher in males (OR=0.403), children having guardians with better educational backgrounds (OR=2.835), children having parents with better income (OR=0.406) and children having mothers as guardians (OR=0.328). Conclusions Gender of the children, educational background of their guardians, income of their parents and types of their guardians are factors affecting the vaccination of five routine vaccines in immunization program in the left-behind children. Mothers who work outside the home have the greatest impact on the vaccination of the left-behind children. The coverage rate of routine immunization in the left-behind children in Yueyang City should be improved in future.
