Influenza vaccination coverage rates among diabetes sufferers, predictors of adherence and time trends from 2003 to 2010 in Spain

 Abstract

A descriptive cross-sectional study was conducted for adults (aged ≥ 50 y) with diabetes. Data was obtained from the 2009 European Health Interview Survey for Spain and the 2003 and 2006 Spanish National Health Surveys. To assess influenza vaccination status, we considered the response (yes or no) to the question “Have you received the influenza vaccine in the previous season?” Both dependent and independent variables were based on the survey questionnaires. The independent variables analyzed included socio-demographic characteristics, health-related variables and use of health care services.
The coverage among adults with diabetes in 2010 was 65.0% (95% CI: 62.1–67.7) compared with 41.2% (95% CI 40.0–42.4) for those without diabetes (p < 0.01) adjusted OR 1.67 (95% CI: 1.40–1.99). The positive predictors of vaccine uptake among diabetic adults were: higher age, being male, the presence of associated chronic conditions and physician visits in the last 2 wk.
The vaccine uptake among adults with diabetes was 61.4% (95% CI: 57.9–64.8) in 2003 and 63.8% (95% CI: 60.7–66.8) in 2006.The adjusted OR of having been vaccinated in 2010 with respect to 2003 was not significant 1.18 (95% CI: 0.97–1.44).
We conclude that the levels of influenza vaccination coverage are below desirable levels among adults with diabetes. Furthermore, trend analysis in influenza vaccination coverage indicates that influenza vaccination rates in adults with diabetes have not improved in recent years. Urgent strategies for increasing vaccination coverage among diabetes sufferers are necessary especially for those aged 50–59, women, those without chronic conditions and those who are not frequent users of health care services.
