Anxiety during pregnancy is associated with adverse outcomes in mothers and infants. Unfortunately, as anxiety is often synonymously mentioned with depression, the studies focusing solely on anxiety during pregnancy are not as robust as those in the field of depression are. In this work, we provide an overview of what is currently known about general anxiety during pregnancy, pregnancy-related anxiety and the potential impacts anxiety could have on post-partum care. An overview of potential risk factors, post-partum maternal outcomes, infant outcome along with pharmacological and nonpharmacological treatments are covered with a specific focus on high-risk pregnancies. Although anxiety during pregnancy is normative; anxiety can become problematic and negatively impact upon behavior, resulting in potential harm to the mother, as well as her developing fetus or child (ren) at home. The clinical diagnosis for anxiety and conditions associated with anxiety often require lengths of time that are not applicable for the pregnant patient, which has led to diagnosis and terms such as pregnancy-related anxiety. Importantly, increasing awareness about the increased potential risk to mothers who may be affected by anxiety during pregnancy or the post-partum period has the potential to improve maternal mental health screening and access to care.
