Ninety percent of the 36,000 annual influenza deaths occur in people over 65, yet only 64% of those over 65 receive the influenza vaccination (IV). Using data from BRFSS, this cross-sectional study examined the effects of receipt of recommended preventive care services such as mammography, sigmoidoscopy, PSA testing, and pneumonia vaccination on IV receipt, as well as effect modification by health risk taking behaviors (HRTBs) (e.g. sedentary lifestyle, smoking, heavy drinking). Logistic regression models provided odds ratio estimates; effect measure modification was evaluated as departures from additivity. For both men (n=17,874) and women (n=33,061), the adjusted odds of receiving an IV were greater for those who received preventive services within the recommended time frame than for those who did not (ORs for women: 1.7 (sigmoidoscopy), 3.0 (mammography), 7.8 (pneumonia vaccine) 3.7 (all three); ORs for men: 1.3(PSA test), 2.1 (sigmoidoscopy), 8.2(pneumonia vaccine ) 3.8 (all three)). In most cases, among those who received preventive services, those with 1 or 2 HRTBs had the highest odds of having received IV, followed by those with 0 HRTBs and those with 3 or more. For those who did not receive preventive services, there was general downward trend in odds across the HRTB categories. These findings suggest that access to preventive care and the opportunities for health provider contact it presents are important determinants of vaccination. The positive effects of preventive service use are modified by health risk taking. This link may be important for the planning of future vaccination interventions.
