The American College of Medical Genetics and Genomics (ACMG) recommends carrier screening for all pregnant women regardless of race or ethnicity. In recent years, the ACMG broadened the guidelines to include expanded carrier screening (ECS) which can screen for 112 conditions. This study seeks to explore the perceptions of pregnant Latina women about the benefits and concerns related to ECS use. Partnering with prenatal clinics in Texas, we conducted semi-structured qualitative interviews with 32 pregnant Latina women in their second or third trimester of pregnancy. NVivo 8 was used to conduct content analysis and emergent coding of the data. Participants reported the benefits of ECS as helping them prepare for the baby’s arrival, informing them of the baby’s risk for genetic conditions, ensuring the health of their baby, and preventing diseases before birth. The ECS-related concerns expressed by the participants included worries surrounding potential positive ECS results, insufficient knowledge about the genetic diseases screened for by ECS, the accuracy of the ECS, the potential harm ECS may cause the baby, and the affordability of ECS. After weighing both their perceived benefits and concerns, nearly all the participants believed that ECS should be offered to all pregnant women. This study contributes to an understudied research area in the genetic/genomic field. Our findings can help increase the awareness of obstetricians, genetic professionals, and other healthcare providers regarding pregnant Latina women’s views on ECS and inform the design of culturally appropriate care as ECS is adopted into routine clinical practice.
