Predictors of H1N1 vaccination in pregnancy.

The purpose of this review was to determine factors that influence a pregnant woman's acceptance of the H1N1 vaccine with the use of the Health Belief Model (HBM). A self-administered questionnaire based on the HBM was used in a cross-sectional study of postpartum women during the 2009 H1N1 epidemic. Overall, 212 postpartum women were approached and agreed to participate; of these women, 25.5% had received an H1N1 vaccination. Perceived barriers to vaccination (P = .001) and perceived severity of infection (P = .018) were independent predictors of vaccination. The total predictive utility of the full model that incorporated HBM dimensions, age, race, care provider, and education level was moderate (area under the curve, -0.86). The addressing of perceived barriers (such as fear of side-effects), an explanation of the safety of the vaccine for the fetus, and the stressing of complications that are associated with H1N1 infection in pregnancy may increase the rate of vaccination.
