Final answer:
Risk factors for hydatidiform mole include advanced maternal age and multiparity, low maternal BMI, and lack of prenatal care.
Step-by-step explanation:
Risk factors for hydatidiform mole include advanced maternal age and multiparity, low maternal BMI, and lack of prenatal care. Advanced maternal age refers to women who are 35 years or older when they become pregnant. This risk factor is supported by various studies that have observed an increased incidence of hydatidiform mole in older women. Multiparity, which means having multiple previous pregnancies, also increases the risk. Additionally, low maternal BMI and lack of prenatal care have been associated with higher chances of developing hydatidiform mole.
