Risk factors for gestational trophoblastic disease: Case - control study.

Abstract

A case-control study was designed to evaluate risk factors for gestational trophoblastic disease. At Arzobispo Loayza Hospital, between 1984 lo 1992. The incidence of hydatidyforme mole was 4,711000 deliveries. Mean age of the study group was 28,42 years. High school level of education was associated with lower risk (OR=0,48; CI=0,233-0,98). Socioeconomic status was not related to risk. No effect of protection or risk was related to the parity of the patients. Women with the disease bad an average age at first pregnancy (19,97 years) lower than that of controls (21,22 years). The personal history of previous gestational trophoblastic disease was associated with an odds ratio of 6.51; however, it was without significance (p=0,101).
