| Objective: To know the proper-age children’s vaccination rate, qualified vaccination rate and timely vaccination rate in all of towns in Yu’an district and the probable influencing elements, evaluate subjectively the work quality of national immunization program and provide evidences for health administrative department to formulate targeted policies of management work of national immunization program. Methods: The sampling method is to adopt the finite probability sampling which can evaluate the township vaccination rate to investigate 1100 children born from September 1st, 2009 to August 31 st, 2011 in 110 administrative villages in 22 towns in Yu’an district. The investigation adopts the method of household survey. Inquire, consult and fill out unified questionnaire. The survey content includes children’s name, gender, date of birth, date of vaccination, vaccine varieties, non-vaccinated reasons and etc. The type of investigated location, landform, the relation between the children’s information provider and children, the education degree of children’s mother, the education degree of children’s father, age group of children, children’s nationality, children’s birthplace, household type of children, the vaccination place children often goes, the distance from home to vaccination place, the transportation method from home to vaccination place, the required time for one-way, main approaches of acquiring the vaccination information and etc. function as probable influencing elements to be counted and analyzed. The establishment of the database is by the use of the software EpiData3.1 and adopts consistency verification after double machine type-in to insure the quality of data. The counting and analysis use EXCEL2003 and SPSS18.0 in which single-element analysis adopts chi-square test and spearman related coefficient analysis and multi-element analysis adopts unconditional logistic regression analysis. Results: 1. The building cards rate, the building certificate rate and the same rate of cards and certificates in all towns in Yu’an district are all 100%. Rate of BCG scar of township level is 48% to 100%. 2. In terms of vaccination rate, except some dose in some towns, vaccination rate of each vaccine and each dose in all towns all keeps over 95% which accords properly with the given overall estimated value 95%. 3. In terms of qualified vaccination rate, in 18 doses’ qualified vaccination rate, 13 doses’ mean value of qualified vaccination rate in all towns reach to 90%, occupying 72.22%. There are 6 doses’ qualified vaccination rate existing differences among the towns, occupying 75%. In the single fully qualified vaccination rate among 8 vaccines, there are only 3 vaccines whose mean value of the single fully qualified vaccination rate reaches to 90%, occupying 16.67%. There are 6 kinds of vaccines’ single fully qualified vaccination existing differences among the towns, occupying 75.00%. The mean value of the covering rate of the ‘five kinds of vaccines’ in all towns is only 82.18%. There are 14 towns whose covering rate of the ‘five kinds of vaccines’ does not reach to 85%, occupying 63.64%. The mean value of the covering rate of the ‘eight kinds of vaccines’ is only 42.09%. There are 14 towns whose covering rate does not reach to 50%, occupying 63.64%. 4. In terms of the timely vaccination rate, the mean value of the first dose’s timely vaccination rate of hepatitis B vaccine in all towns is 94.64%, and there are 4 towns whose mean value is lower than 90%; the mean value of the first dose’s timely vaccination rate of measles-containing vaccine in all towns is 65%, and there are 22 towns whose mean value is lower than 90%. There exist differences among all towns on the first dose’s timely vaccination rate of measles-containing vaccine. The second dose’s timely vaccination rate of measles-containing vaccine in all towns is 47.91%, and there are 22 towns whose mean value is lower than 90%. There exist differences among all towns on the second dose’s timely vaccination rate of measles-containing vaccine 5. Multi-element logistic regression analysis shows that the influencing elements causing low covering rate of the ‘eight kinds of vaccines’ are the education degree of children’s father, main approaches of acquiring the vaccination information and the distance from home to vaccination place. The influencing element of the first dose’s timely vaccination rate of hepatitis B vaccine is the education degree of children’s father. The influencing elements of the first dose’s timely vaccination rate of measles-containing vaccine are the relation between the children’s information provider and children, the education degree of children’s father, age group of children and main approaches of acquiring the vaccination information. The influencing elements of the second dose’s timely vaccination rate of measles-containing vaccine are age group of children and main approaches of acquiring the vaccination information. Conclusions: 1. Proper-age children’s vaccination rate of each vaccine and dose in all towns in Yu’an district is at a high level. The vaccine coverage is satisfying. 2. The qualified vaccination rate and the timely vaccination rate of two doses of measles-containing vaccines in the majority of towns in Yu’an district are not ideal, indicating that there is still large space for improving the quality of preventive vaccination at the basic level. 3. From the multi-element logistic analysis of the fully qualified vaccination of eight kinds of common vaccines for children and the first dose’s timely vaccination rate of hepatitis B vaccine and the timely vaccination of measles-containing vaccines, it can be seen that the education degree of children’s father and main approaches of acquiring the preventive vaccination information are the major influencing factors. Therefore, we should enhance the efforts to spread the knowledge of preventive vaccination among children’s parents. |
