Questions: When does a mother's age present a greater risk for having pregnancy complications including anemia, and high blood pressure? 35 years old 25 years old 45 years old 15 years old or younger

The answer is 45 years old.

Explanation for each option:

1. 35 years old: While being 35 years old is considered advanced maternal age, which can increase the risk of certain complications, it is not as high risk as being 45 years old. Women at this age may face increased risks, but they are generally lower than those faced by older mothers.

2. 25 years old: This is generally considered an optimal age for pregnancy with the lowest risk of complications. Women in this age group typically have fewer health issues related to pregnancy.

3. 45 years old: At this age, the risk for pregnancy complications, including anemia and high blood pressure, is significantly higher. Advanced maternal age (over 35, and especially over 40) is associated with increased risks for both the mother and the baby, including gestational diabetes, preeclampsia, and chromosomal abnormalities.

4. 15 years old or younger: Teenage pregnancies can also present increased risks, including anemia and high blood pressure, due to the mother's body not being fully developed. However, the risks associated with advanced maternal age (45 years old) are generally considered more significant.

In summary, while both very young and older maternal ages present risks, 45 years old is associated with the greatest risk for pregnancy complications.
