Abstract:Objective To investigate the current status of vaccination among the left-behind children in Shen County, Shandong Province and its influencing factors so as to provide a scientific basis for controlling the prevalence of infectious diseases among local left-behind children. Methods A multistage sampling method was used to select 1,200 left-behind children in Shen County, Shandong Province from June to September, 2016. Self-designed questionnaires were employed to investigate the current situation of vaccination among the left-behind children, and logistic regression analysis was performed to identify the factors influencing their vaccination status. Results The vaccination rate and qualified inoculation rate for the five vaccines (inculding bacille calmette-guerin (BGG) vaccine, hepatitis B (HepB) vaccine, oral poliomyelitis attenuated live vaccine (OPV), diphtheria-tetanus-pertussis (DTP) vaccine and measles vaccine (MV)) in the left-behind children were 91.41% and 81.35%,with the highest rates for BGG vaccine (95.67%, 90.16%) and the lowest for MV (87.75%, 76.08%). Univariate analysis indicated that there were statistically significant differences in the qualified inoculation rate of the five vaccines among different age groups, caregivers with different identity, different monthly household income groups as well as between only-child group and non-only-child group and between vaccination card group and non-vaccination card group (all P<0.05).Logistic regression analysis revealed that the age of 3-, 4- and 5- years, caregivers being grandparents, being the only child and establishment of vaccination cards were independent influencing factors of vaccination.The left behind children at the age 3- years(OR=1.609,95%CI:1.029-2.516), 4- years(OR=1.846,95%CI:1.414-2.408),5- years (OR=2.305,95%CI:1.071-4.960), with caregivers being grandparents (OR=2.157,95%CI:1.071-4.344) had higher risk of unqualified inoculation. However, the left behind children being the only child (OR=0.638,95%CI:0.411-0.991) and having vaccination card (OR=0.601,95%CI:0.390-0.928) had lower risk of unqualified inoculation. Conclusions The current situation of immunization in the left-behind children in Shen County is not optimistic. The qualified inoculation rate of MV in the left-behind children is the lowest, and there is still a risk of measles outbreak. It is necessary to strengthen the service capacity building of grass-roots medical institutions and the propaganda of immunization knowledge in the rural areas and conduct school children’s vaccination certificate inspection so as to improve the children’s vaccination rate and qualified inoculation rate.
