Purpose: This study is aimed to identify the influenza vaccination rate and to estimate the effect with chronic diseases in the high risk group of adults in Korea.
Method: Using the data from the 7th Korea National Health and Nutrition Examination Survey(KNHANES Ⅶ), this study is conducted by a complex sample analysis. The influenza vaccination coverage was determined in adults aged 19 years or older. Among them, factors affecting immunization were identified in 5,650 patients with chronic diseases. The analysis was performed using logistic regression, and Rao-Scott chi-square test.
Results: The influenza vaccination coverage in adults was 37.1%. Compared to those without chronic disease, patients with chronic disease reported higher vaccination rate. Among those with chronic diseases, the vaccination rate was 38.1% for under 65 and 86.0% for over 65. When analyzed, excluding those aged 65 or over, who were eligible for free vaccination under the National Immunization Program (NIP), the coverage of vaccination was 2.28 times higher in married people and 2.23 times higher in Medical aid program. On the other hand, the vaccination rate in people with minors among family members was 0.75 times lower.
Conclusion: The beneficiaries of NIP and medical aid programs received a free vaccine and had high immunization rates. This indicated that free vaccination can be considered as the main factor of influenza vaccination. On the basis of this, free vaccination can be considered as the main cause of vaccination.
