Cross-sectional study to assess awareness of cytomegalovirus infection among pregnant women in Germany

BACKGROUND

Study aimed to assess awareness of congenital cytomegalovirus (CMV) infection and its determinants in pregnancy.

METHODS

Cross-sectional survey was conducted in five hospital-based maternity units in Germany. Pregnant women attending the maternity departments completed interviewer/self-administered survey questionnaire. High-risk group was defined according to contact with children under five years of age (at home or at work). Quantitative analyses using multivariable logistic regression were performed.

RESULTS

One thousand two hundred thirty-three pregnant women were included. 48.5% (n = 598) of women reported any knowledge about risk of CMV infection during pregnancy. CMV infection was less known than other infections or diseases (education about toxoplasmosis 95.5% (n = 1,177), listeriosis 60.5% (n = 746). 38% (n = 468) of participants received education about CMV. CMV awareness was associated with the level of education and employment in childcare or medical care. Only 32% (n = 394) of the women made use of serological screening for CMV during pregnancy (individual health service). 40.8% (n = 503) of pregnant women were classified as high-risk group. They had significantly higher knowledge and education about CMV, and msignificantlycant more often use of the serological screening.

CONCLUSIONS

Less than half of pregnant women surveyed were aware of potential risk associated with CMV infection during pregnancy. In our study,one-third third of pregnant women made use of the serological screening for CMV. Regarding the lack of current consensus on the role of serological CMV screening for pregnant women, hygiene preventive measures are the only evidence-based recommendation for pregnant women and knowledge increase could potentially have major public health impact.

Periconceptional folic acid supplement use among women of reproductive age and its determinants in central rural Germany: Results from a cross sectional study

BACKGROUND

Prevalence of neural tube defects (NTD) has not decreased in Germany despite longstanding recommendations for folic acid supplementation. To examine the prevalence of periconceptional folic acid supplement use and associated factors among German women of reproductive age.

METHODS

Cross-sectional survey was conducted in hospital-based maternity units in rural Germany. A sample of 1,004 women of reproductive age, either pregnant or in their early postpartum period, took interviewer/self-administered paper-based survey questionnaire. Prevalence of periconceptional folic acid supplement use was assessed, where periconception was defined as 1 month prior to and 3 months post-conception. Prevalence odds ratios (POR) and 95% confidence intervals (CI) using crude and adjusted logistic regression analysis were estimated to examine determinants of folic acid supplement use.

RESULTS

Prevalence of folic acid supplement use was 41.5% (95% CI: 37.7%, 45.7%). Multivariable analysis showed lack of educational qualifications, unplanned pregnancy, later diagnosis of pregnancy, increased parity, and not having an awareness of importance of folic acid for optimal pregnancy outcomes were associated with not taking periconceptional folic acid supplements. Books, doctors, friends, media, were sources of information.

CONCLUSION

Periconceptional folic acid is sub-optimal in rural Germany and thus failing to prevent NTDs. Targeted promotion of folic acid supplement use should be conducted periodically by gynecologists and primary care physicians during annual medical screenings. Mandatory folic acid fortification of staple foods is a complementary approach to overcome limitations of individual behaviors of folic acid supplement intake, and should be considered as it has been proven effective in multiple countries.
