Risk of Molar Pregnancy Among Ethnic Groups

Gynecol Oncol; ePub 2016 July 30; Melamed, et al

Race/ethnicity is a significant risk factor for both complete and partial pregnancy in the United States, specifically in the northeastern US, according to a recent study. The cross-sectional study included women who were followed for complete or partial mole and those who had a live singleton birth in the northeastern US between 2000 and 2013. Researchers found:

• 140 cases of complete mole, 115 cases of partial mole, and 105,942 live births were identified.

• After age adjustment, Asian women were more likely to develop complete mole (RR, 2.3) but less likely to developed partial mole (RR, 0.2) than white women.

• Black women were significantly less likely than white women to develop partial mole (RR, 0.4); but marginally less likely to develop complete mole (RR, 0.6).

• Hispanic women were less likely than white women to develop complete mole (RR, 0.4) and partial mole (RR, 0.4).
