Аннотация
The relation between age of parents and the risk of complete and partial hydatidiform mole was examined using data from a case-control study conducted in Northern Italy of 149 histologically confirmed complete moles, 45 partial moles and 306 controls subjects who delivered normal babies. Compared to women aged 21 to 35, the relative risk (RR) of complete mole was elevated for teenage women (RR = 1.9) and for those aged 36-40 (RR = 1.9) or over 40 (RR = 7.5). There was no association between women's age and partial mole. Likewise, older paternal age (greater than 45) was related with the risk of complete mole (RR = 4.9, though allowance for women's age reduced this point estimate to 2.9), but not of partial mole. The present findings indicate that there are important differences in the epidemiology of complete and partial hydatidiform mole.
