title: A Population-Based, Nationwide Cross-Sectional Study on Influenza Vaccination Status among Cancer Survivors in Korea.
abstract: Cancer survivors are at increased risk of developing influenza-related complications. The purpose of this study was to investigate the vaccination coverage among cancer survivors in Korea using the Korea National Health and Nutrition Examination Survey (KNHANES). Adult cancer survivors were selected from fourth (2007-2009) and fifth (2010-2012) KNHANES (n = 1156) datasets. General characteristics, cancer-related data, and influenza vaccination status were collected using self-report questionnaires. Chi-square tests and multiple logistic regression analyses were performed to investigate the association between influenza vaccination coverage and associated factors. Overall, 51% of survivors were vaccinated. Vaccine prevalence exceeded 75% in those more than 65 years but was only 26% in survivors aged 19-44. Increasing age, low frequency of alcohol consumption, having poor self-rated health, and having a shorter duration since cancer diagnosis were significant predictors of vaccination status among cancer survivors under 65 years of age. Influenza vaccine coverage remains much lower than recommended among cancer survivors, particularly in the younger age groups. Further study is needed to determine the factors that contribute to the lack of vaccination in cancer survivors, despite their increased risk for influenza.
