Prenatal Counseling on Seasonal Influenza Vaccination and Seasonal Influenza Vaccination among Pregnant Women in Los Angeles County: Findings from the 2010 LAMB Project
Pregnant women are at increased risk of hospitalization from influenza and related complications. CDC and ACOG recommend prenatal counseling/education on influenza vaccination (PCSIV) and vaccinating pregnant women with inactivated influenza vaccine during the influenza season regardless of gestational age.
Methods:
We analyzed 2010 Los Angeles Mommy and Baby (LAMB) survey data. LAMB is a population based survey that uses stratified random sampling method and surveys women who gave live birth in Los Angeles County (LAC). Women were asked whether health care provider discussed “getting a flu vaccine during pregnancy” during the prenatal care visits and whether they got flu shot during pregnancy. Weighted prevalences were calculated to account for the survey sampling design. Multiple logistic regression was used to estimate the association between the prevalence of PCSIV and seasonal influenza vaccination (SIV) adjusted to the respondent’s race/ethnicity, age, education and Health insurance plan.
Results:
Among women who completed surveys, reported having prenatal care and responded to the questions related to SIV (n=6332) and PCSIV (n=6288) 46.7% (95%CI= 44.9%-48.5%) and 73.0% (95%CI= 71.3%-74.6%) reported SIV and PCSIV respectively. Analysis of data showed that women who reported PCSIV were more likely to get seasonal influenza vaccine during pregnancy (OR=19.0, 95%CI= 14.3-25.4). After adjustment to the potential confounders the association between SIV and PCSIV remained significant (aOR=17.5, 95%CI=13.1-23.4).
Conclusion:
More than a half of LAC mothers who gave live birth in 2010 did not report SIV during pregnancy. Moreover, more than a quarter of respondents did not receive PCSIV. There is a very strong association between getting seasonal influenza vaccine during pregnancy and PCSIV, suggesting, that PCSIV may play an important role in increasing SIV coverage among LAC pregnant women.
