Objective: The aim of the study wasto describe the past medical history, sociodemographic, and pregnancy characteristics of women at high risk for aneuploidy and to determine which factors are related to her choice of cell-free DNA (cfDNA) testing instead of invasive diagnostic testing.Methods: We conducted a prospective descriptive study including pregnant women from the Western Barcelona public health area at high risk for fetal aneuploidy, defined as a trisomy 21 or 18 risk between 1/10 and 1/250 at the combined first-trimester or at the second-trimester biochemical screening. During 1 year (December 2018 to November 2019), these women were asked to fill in a confidential questionnaire about her past medical history, demographic and pregnancy characteristics, and her opinion about termination of the pregnancy after a counseling consultation with a maternal-fetal medicine specialist in which advantages and disadvantages of both testing methods, cfDNA or diagnostic testing, were discussed. Logistic regression analysis was used to determine which factors were related with cfDNA uptake.Results: During the study period, 82 pregnant women filled the questionnaire. The median maternal age was 39.6 years (interquartile range [IQR] 37.3-40.9 years), and 73 (89%) of them were 35 years or older. Forty-three (52%) women opted for cfDNA testing, while 39 (48%) chose invasive diagnosis. In a logistic regression analysis, the use of assisted reproductive techniques (OR 13.03; 95% CI: 1.47-115.56; p = 0.021) and Latin American origin (OR 6.66; 95% CI 1.73-25.66; p = 0.006) were shown to be related to a higher cfDNA uptake. In contrast, nonreligious women (OR 0.21; 95% CI: 0.06-0.72; p = 0.013) and a favorable opinion about termination of pregnancy (OR 0.23; 95% CI: 0.06-0.92; p = 0.037) were related with a lower uptake.Conclusion: Half of the pregnant women at high risk for fetal aneuploidy opted for cfDNA testing. The main reason to choose cfDNA was avoiding the risk of pregnancy loss. Women using assisted reproductive techniques and those of Latin American origin preferred cfDNA testing, while nonreligious women and those with a favorable opinion on termination pregnancy preferred invasive testing.
