Retention of the mother and child health handbook and additional immunization of Japanese encephalitis and tetanus vaccine.

BACKGROUND

Improvement of additional immunization rate is indicated as an important factor for effective immunization of diseases. In this study, the relationship between retention of mother and child health handbook and additional immunization rate of Japanese encephalitis and tetanus was examined.

METHODS

A survey via questionnaire was performed against parents of students of middle schools in Gwangmyeong-si, Gyeonggi-do, and elementary schools in Seoul. Among 350 copies of the questionnaire delivered via post mail, 261 copies were collected and used in the analysis. The questionnaire included general features of subjects and their children, retention of the mother and child health handbook, and recognition of additional immunization of the Japanese encephalitis and tetanus vaccine.

RESULTS

It was found that 80.8% of subjects answered affirmative to retaining the mother and child health handbook, and the group retaining the handbook had higher recognition rate of the need for additional immunization than the group that did not, for the Japanese encephalitis vaccine (83.2% vs. 51.2%, P < 0.001) and for the tetanus vaccine (66.5% vs. 31.7%, P < 0.001). Although the group retaining the handbook had a significantly higher additional immunization rate of the tetanus vaccine of 48.6% vs. 17.1% (P = 0.001), the immunization rate of the Japanese encephalitis vaccine did not show a significant difference (P = 0.231). The group recognizing the need for additional immunization of the Japanese encephalitis and tetanus vaccine had a significantly higher additional immunization rate than the counterpart (P < 0.001).

CONCLUSION

It was considered that retention of the mother and child health handbook was related to recognition and execution of additional immunizations.
