Influenza Vaccination Coverage Rate according to the Pulmonary Function of Korean Adults Aged 40 Years and Over: Analysis of the Fifth Korean National Health and Nutrition Examination Survey

Abstract

Influenza vaccination is an effective strategy to reduce morbidity and mortality, particularly for those who have decreased lung functions. This study was to identify the factors that affect vaccination coverage according to the results of pulmonary function tests depending on the age. In this cross-sectional study, data were obtained from 3,224 adults over the age of 40 who participated in the fifth National Health and Nutrition Examination Survey and underwent pulmonary function testing in 2012. To identify the factors that affect vaccination rate, logistic regression analysis was conducted after dividing the subjects into two groups based on the age of 65. Influenza vaccination coverage of the entire subjects was 45.2%, and 76.8% for those aged 65 and over. The group with abnormal pulmonary function had a higher vaccination rate than the normal group, but any pulmonary dysfunction or history of COPD did not affect the vaccination coverage in the multivariate analysis. The subjects who were 40-64 years-old had higher vaccination coverage when they were less educated or with restricted activity level, received health screenings, and had chronic diseases. Those aged 65 and over had significantly higher vaccination coverage only when they received regular health screenings. Any pulmonary dysfunction or having COPD showed no significant correlation with the vaccination coverage in the Korean adult population.

Vaccination Coverage with the Pneumococcal and Influenza Vaccine Among Persons with Chronic Diseases in Shanghai, China, 2017

“…In our study, less than 1 percent of individuals received an influenza vaccine, which is far lower than in other countries, many of which provide free vaccine through government-sponsored or private insurance programs. Similar studies have shown higher influenza vaccination coverage in the United [38], and Hong Kong (39%, over 65 years, 2015) [35]. Our findings were relatively consistent with prior studies in China showing an average national vaccination coverage ranging between 1.5% and 2.2% in 2004 and 2014 [22].…”

Our findings were relatively consistent with prior studies in China showing an average national vaccination coverage ranging between 1.5 and 2.2% in 2004 and 2014 [22].…”
