Which factor is least likely to be associated with advanced maternal age during pregnancy?

Advanced maternal age, typically defined as being 35 years or older during pregnancy, is associated with several medical risks and outcomes. One of the primary concerns is that as maternal age increases, there is a greater likelihood of genetic and chromosomal abnormalities occurring in the fetus. This is due to factors such as decreased oocyte quality and increased risk of errors during cell division. Therefore, an increased possibility of chromosomal abnormalities is strongly correlated with advanced maternal age.

In addition, studies have shown that older mothers are at a heightened risk for developing pregnancy-related complications such as preeclampsia, which involves high blood pressure and potential damage to various organ systems. Another notable aspect is the risk of multifetal pregnancies. As women age, they may experience changes in fertility treatments that can increase the chance of multiple pregnancies, such as the use of assisted reproductive technology.

On the other hand, the statement about lower likelihood of gestational diabetes is less consistent with clinical findings. In fact, research indicates that older maternal age can also increase the risk of gestational diabetes, making the option about lower likelihood the least likely to be associated with advanced maternal age during pregnancy.
