A significant association between maternal age and FF was not found (p = 0.12). A lower FF was associated with a rise in the incidence of gestational diabetes mellitus (p = 0.02) and a higher FF was associated with a rise in the incidence of fetal growth restriction (p &lt; 0.001). However, high or low FF was not associated with pre-eclampsia, premature rupture of membranes, birth weight, or delivery time. No significant association was found between FF and multiple of the median of pregnancy-associated plasma protein-A and free &lt;span style=&quot;background:white&quot;&gt;&amp;beta;-&lt;/span&gt;human chorionic gonadotropin.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;br&gt;
