Adolescent immunization rates and the effect of socio-demographic factors on immunization in a cosmopolitan city (ERZURUM) in the eastern Turkey.

Objective: Pediatric vaccinations have decreased the incidence and mortality from infectious diseases in children, but adolescents continue to be adversely affected by vaccine preventable disease. The present study was performed to determine the status of adolescents immunization and to investigate the effect of several socio-demographic factors on immunization.

Material And Method: Using the cluster-sampling method, 817 adolescents were selected in 24 high schools (15,000 students) in central district of Erzurum (Turkey). Adolescents were categorized as completely vaccinated, incompletely vaccinated, unvaccinated or vaccination status unknown.

Results: Of the 817 adolescents, 6.9% were completely vaccinated, 24.4% were incompletely vaccinated and 64.1% were unvaccinated. The vaccination status of 4.6% of adolescents was unknown. A significantly correlation was seen between the number of siblings, the level of mother and father education, the level of parent's socio-economics status, health insurance and immunization status.

Conclusion: Our findings indicated a small percentage of adolescents receive all of the recommended vaccine. In immunization programs in Turkey, priority should be given to increase adolescent immunization rate with a middle school and/or adolescents, vaccination.
