MONTIEL, Dora; SAMUDIO, Margarita  and  JAROLIN, Magali. Coverage and related factors of vaccination anti-influenza in pregnant women who attend the National Hospital in the period March-September 2017. Rev. cient. cienc. salud [online]. 2021, vol.3, n.1, pp.14-25. ISSN 2664-2891.


Influenza in pregnant women can be serious; vaccination is the measure to prevent complications of this disease. Objective: To determine the coverage and factors related to anti-influenza vaccination in pregnant women who attended the Department of Gynecology-Obstetrics of the National Hospital between March-September 2017. Methodology: crossectional descriptive observational study. Pregnant women who attended their prenatal care, were surveyed using a questionnaire that included socio-demographic characteristics and on the influenza vaccination. In addition, professionals of the vaccination unit were interviewed about knowledge, availability and registration of the influenza vaccine. Data were entered in an Excel sheet and analyzed by EpiInfo; qualitative variables were expressed as absolute and relative frequency, continuous variables as mean and standard deviation. Chi square test was used at a significance level of 0.05 to establish associations between variables. Results: A total of 384 pregnant women were studied (mean age: 25.6 ± 6.3), 85.7% from the Central Department. 71.4% were in the third trimester of pregnancy, 83% with sufficient prenatal control, 10% had comorbidity. Influenza vaccine coverage was 62.24%, which was associated (p <0.05) with sufficient prenatal control (2.0; 95% CI: 1.2-3.3), previous vaccination (1.9; 95% CI: 1.3-2.9), received a recommendation from the doctor (10.9; 95% CI: 5.9-20.1), and have information about the vaccine (15.8; 9595% CI: 8.4-29.7). Conclusion: Vaccination coverage was suboptimal. It is urgent to reinforce educational and information strategies to pregnant women during the prenatal care visit.
