Differences in medication beliefs between pregnant women using medication, or not, for chronic diseases: a cross-sectional, multinational, web-based study.

OBJECTIVES

To assess whether medication beliefs differ between women who use or not use medication for their somatic chronic diseases during pregnancy and whether this association varies across diseases.

DESIGN

Cross-sectional web-based survey.

SETTING

Multinational study in Europe.

PARTICIPANTS

Pregnant women or women with children less than 1 year old from European countries and with asthma, allergy, cardiovascular, rheumatic diseases, diabetes, epilepsy and/or inflammatory bowel diseases (IBD).

PRIMARY AND SECONDARY OUTCOME MEASURE

Differences in scores of the (BMQ).

RESULTS

In total, 1219 women were included (ranging from 736 for allergy to 49 for IBD). Women using medication for their chronic disease (n=770; 63%) had higher scores on the BMQ subscales (16.6 vs 12.1, p<0.001) and (16.2 vs 15.4, p<0.001), and lower values on the subscales (12.5 vs 13.1; p=0.005) and (9.8 vs 10.7, p<0.001) than women not using medication. No significant differences were shown for the subscale (12.5 vs 12.3, p=0.484). Beliefs varied somewhat across diseases but in general more positive beliefs among women using medication were shown. Epilepsy was the disease where less differences were observed between women using and not using medication.

CONCLUSION

Women's beliefs were associated with medication use during pregnancy with only small differences across the diseases. Knowing pregnant women's beliefs could help identify women who are reluctant to use medication and could guide counselling to support making well-informed treatment decisions.
