[h=3]Abstract[/h] [h=4]OBJECTIVE:[/h] Epidemiological research has posited a 'healthy user' bias in patients receiving influenza vaccination; thus we sought to evaluate potential healthy-user attributes and their associations with influenza vaccination.
[h=4]RESEARCH DESIGN & METHODS:[/h] Between 2011 and 2013, adults with type 2 diabetes were enrolled in a prospective cohort in Alberta, Canada. Information collected included sociodemographics, diabetes-related data (e.g., duration, complications), health behaviors (e.g., smoking status), functional health status, and satisfaction with healthcare. Data were collected by a mailed, self-administered survey. Multivariable logistic regression analyses were used to identify potential healthy-user attributes independently associated with influenza vaccination.
[h=4]RESULTS:[/h] From a cohort of 2040 patients, 1287 (63%) reported receiving the influenza vaccine in the previous year. Average age of the cohort was 64 years (standard deviation 11) and 55% were male. In multivariable analysis, attributes independently associated with influenza vaccination included receiving preventive medications: aspirin (64% vs 44%; adjusted odds ratio, aOR 1.65, 95% CI 1.34-2.04); blood pressure medications (76% vs 56%; aOR 1.36, 95% CI 1.07-1.71); and cholesterol-lowering medications (74% vs 53%; aOR 1.50, 95% CI 1.19-1.89), as well as having a healthcare professional check feet for lesions (47% vs 31%; aOR 1.39, 95% CI 1.12-1.74). Additional covariates independently associated with influenza vaccination included: age over 65 years, respiratory disease, the number of additional comorbidities, and higher ratings of healthcare experience.
[h=4]CONCLUSION:[/h] Vaccinated diabetic patients exhibit many postulated attributes of 'healthy users', which has implications for the interpretation of epidemiological studies of influenza vaccine effectiveness, as well as targeting future vaccination campaigns.
