Final answer:
Hydatidiform mole, also known as molar pregnancy, is a rare condition characterized by the abnormal growth of cells in the uterus during early pregnancy. Advanced maternal age is considered a contributing factor, as the incidence of having a fetus with trisomy 21 increases with age. Adequate folic acid intake, normal chromosomal makeup, and early prenatal care do not specifically contribute to hydatidiform mole.
Step-by-step explanation:
Hydatidiform mole, also known as molar pregnancy, is a rare condition that occurs when there is an abnormal growth of cells in the uterus during early pregnancy. It is characterized by the presence of a mass of cysts instead of a normal embryo and placenta.
Advanced maternal age, or being over the age of 35, is considered a contributing factor to hydatidiform mole. Research has shown that the incidence of having a fetus with trisomy 21 (Down syndrome) increases dramatically with maternal age.
Adequate folic acid intake is important for normal fetal development, but it is not specifically mentioned as a contributing factor to hydatidiform mole. However, a deficiency in folic acid can lead to certain birth defects.
Normal chromosomal makeup is not a contributing factor to hydatidiform mole. In fact, hydatidiform mole is often associated with chromosomal abnormalities in the fertilized egg.
Early prenatal care is important for monitoring the health of both the mother and the fetus, but it is not specifically mentioned as a contributing factor to hydatidiform mole.
